Description

LOUDSPEAKER LAMP UNIT Field of the invention The present invention relates to acoustics and to loudspeakers, morespecifically to a loudspeaker lamp unit and to a method for assembling aloudspeaker lamp unit.

Background artWith the advance in technology, loudspeakers as they are commonly known are developing into devices that not only provides the acousticalperformance that is desired but that also functions as an independent unitwhich removes the need for a dedicated amplifier. l.e., active loudspeakerswith integrated amplifiers and which allows wireless and/or wired connectionof a mobile device such as a telephone are becoming more popular.

Such devices provide many benefits in terms of allowing moreaesthetically pleasing appearances to the loudspeakers and further facilitatespositioning of the loudspeakers as it does not have to be connected to anyseparate amplifier. lt is generally desired that speakers and sound systems are integratedinto the home such that they form part of a furniture arrangement. As a part ofenabling this, devices such as combined loudspeaker and lamp units (e.g.IKEA SYMFONISK Table lamp) have been introduced. However, providing aloudspeaker that should also function as a lamp may generate certainproblems in achieving the satisfactory performance from the loudspeaker. lt isthus desired to provide an improved combined loudspeaker and lamp unit.

Summary of the invention ln view of that stated above, the object of the present invention is toprovide a combined loudspeaker lamp unit that ameliorates at least some ofthe problems with prior art solutions. lt is further an object to provide amethod for assembling a loudspeaker lamp unit.

To achieve at least one of the above objects and also other objectsthat will be evident from the following description, there is provided accordingto the present invention a loudspeaker lamp unit comprising: a base comprising a Ioudspeaker arranged inside the base and a lampsocket arranged at a top of the base being configured to receive a lightsource, a lamp shade releasably attached to the top of the base, and a sound reflecting plate arranged at the top of the base and configuredto reflect sound from the loudspeaker emitted in a direction towards the lampshade. The sound reflecting plate thus effectively reduces the risk ofinterference and dampening of sound waves by the lamp shade which couldotherwise detrimentally affect the performance of the Ioudspeaker. The baseand the function of the Ioudspeaker is thus made more independent of thelampshade provided to the loudspeaker lamp unit, which facilitates for a userto modify the loudspeaker lamp unit by replacing and selecting a desired lampshade to be arranged on the base.

The sound reflecting plate may have a radial extension in relation to acentral axis from a bottom of the base to the top of the base that is essentiallyequal to or larger than a radial extension of the base in relation to the centralaxis, thus ensuring that a sufficient amount of the sound emitted from theIoudspeaker is reﬂected away from the lamp shade.

The sound reflecting plate may have a radial extension in relation to acentral axis from a bottom of the base to the top of the base that is less than aradial extension of the lamp shade in relation to the central axis A.

The sound reflecting plate may be formed from a plastic material suchas PET or PMMA. The sound reflecting plate may further be permeable tolight to facilitate light emission from the light source and to avoid the soundreflecting plate causing shadows to form.

The sound reflecting plate may have a thickness of 1 mm to 3 mm,preferably 2 mm.

The sound reflecting plate may comprise a through hole through whichthe lamp socket is insertable, thus facilitating assembly of the Ioudspeakerlamp unit.

The sound reflecting plate may further comprise a top dampening layeron a top surface thereof and a bottom dampening layer on a bottom surfacethereof. The top and bottom dampening layers functions as anti-vibrationgaskets and thus reduces the risk of vibrations from the loudspeaker causingnoises forming from movement between the sound reflecting plate andadjacent components of the loudspeaker lamp unit.

The top dampening layer and/or the bottom dampening layer maycover a respective area on the top surface and the bottom surfacerespectively that is smaller than a total surface area of the top surface and ofthe bottom surface respectively, thus reducing the risk of the top and bottomdampening layers negatively affecting the sound emitted by the loudspeaker.

The loudspeaker lamp unit may further comprise a locking memberconfigured to lockingly attach the lamp shade and the sound reflecting plateto the base. A support structure of the lamp shade may be arranged to abutthe bottom dampening layer and the locking member may be arranged toabut the top dampening layer. The locking member thus secures andarranges the sound reflecting plate and the lamp shade correctly in relation tothe base.

A width of the top dampening layer may correspond to a width of acontact surface of the locking member and a width of the bottom dampeninglayer may corresponds to a width of a contact surface of the support structureof the lamp shade. The top and bottom dampening layers will thus notprotrude outside of the respective contact surfaces and thus not negativelyaffect (e.g. dampen or attenuate) the sound emitted from the loudspeaker.Moreover, sufficient dampening is achieved by the top and bottom dampeninglayers as they cover the width of their respective contact surfaces on thelocking member and on the support structure of the lamp shade respectively.By reducing the area of the dampening layer, a cost efficient solution may beachieved.

The top dampening layer and the bottom dampening layer may beformed from ethylene-vinyl acetate.

The lamp shade may comprise a support structure supporting a fabricshade.

The Ioudspeaker lamp unit may further comprise a Iocking memberconfigured to Iockingly attach the lamp shade and the sound reflecting plateto the base. ln a second aspect is a method for assembling a Ioudspeaker lamp unitprovided. The method comprises: arranging a support structure of a lamp shade to a lamp shade supportstructure of a base arranged at a top of the base, the base comprising aIoudspeaker arranged inside the base, arranging a sound reflecting plate to the top of the base, Iocking the sound reflecting plate and the lamp shade to the base usinga Iocking member.

The method may further comprise: attaching a light source to a lamp socket of the base, the lamp socketbeing arranged at the top of the base.

The sound reflecting plate may be attached to the support structure ofthe lamp shade by means of an adhesive prior to arranging the soundreflecting plate to the top of the base. The sound reflecting plate and the lampshade may thus form a preassembled unit, facilitating assembly of theIoudspeaker lamp unit. Moreover, the desired relative orientation between thelamp shade and the sound reflecting plate can thus be more reliablycontrolled.

Description of embodiments The present invention will now be described more fully hereinafter withreference to the accompanying drawings, in which currently preferredembodiments of the invention are shown. This invention may, however, beembodied in many different forms and should not be construed as limited tothe embodiments set forth herein; rather, these embodiments are provided forthoroughness and completeness, and fully convey the scope of the inventionto the skilled person.

Figure 1 discloses a Ioudspeaker lamp unit 100, i.e. a combinedIoudspeaker and lighting device. The Ioudspeaker lamp unit 100 comprise alamp shade 104. The lamp shade 104 is releasably attached to a base 102and is thus replaceable. The lamp shade 104 may be formed by a number ofdifferent materials such as fabric and/or plastic and/or metals or combinationsthereof. lt should be noted that the present disclosure may be advantageousfor all types of lamp shades that may have a negative influence (e.g. adampening effect) of the quality of audio emitted by the Ioudspeaker lamp unit100.

The base 102 forms the structural portion of the Ioudspeaker lamp unit100 to which the lamp shade 104 is attachable. The base 102 preferablycomprises a Ioudspeaker 108 (shown in Fig. 2) having one or several Ioudspeaker e|ement(s) (not shown). The Ioudspeaker lamp unit 100 ispreferably wirelessly and/or with wired connection connectable to a remotesource such as a mobile device and/or a computer and may thus comprise anaudio amplifier arranged in the base 102 provided with a wirelesscommunications interface (not i||ustrated). Examples of such a wirelesscommunication interface may be B|uetooth® or Wifi® or another similarwireless communication interface.

The Ioudspeaker lamp unit 100 may thus be configured to receivestreaming audio from the remote source which is subsequently emitted assoundwaves by means of the Ioudspeaker 108 of the base 102. A battery (notshown) may be provided in the base 102, the battery may be configured toprovide electric power to components of the Ioudspeaker lamp unit 100.Moreover, the Ioudspeaker lamp unit 100 may be operably connected toreceive power from a mains cable (not shown), which may further beconfigured to provide electric power to be stored in the battery. One orseveral buttons may be provided on the base 102 for controlling theIoudspeaker lamp unit 100 and for instance for wireless pairing with anotherdevice (e.g. a remote source as described above or to another Ioudspeakerlamp unit).

As is common with lighting devices, it may be desired for a user to beable to replace the lamp shade in order to alter the appearance thereof.However, in doing so, the user may for prior art combined Ioudspeaker lampunits inadvertently affect the acoustic properties for the Ioudspeaker. Thelamp shade may reflect, interfere and/or dampen sound emitted from thespeaker elements of the base. To reduce this problem, and to facilitateadaptation of the appearance of the Ioudspeaker lamp unit 100 withoutaffecting the acoustic properties thereof, a sound reflecting plate 106 isaccording to the teachings herein provided. The sound reﬂecting plate 106 isconfigured to reflect sound from the base 102 away from the lamp shade 104such that the Ioudspeaker lamp unit 100 is independent of the type of lampshade 104 that is attached thereto and thus more flexible for modification,more reliable and more robust in its performance.

Fig. 2 shows a perspective view of the base 102. The base 102 ispreferably cylindrically shaped but may be provided with another shape aswell. The base 102 is intended to function as a housing for the electricalcomponents of the loudspeaker lamp unit 100 and as a foot forming a stablestand such that the loudspeaker lamp unit 100 remains upright in a securemanner.

The base 102 comprises a lamp socket 110 arranged at a top 112 ofthe base 102, the lamp socket 110 being configured to receive a light source142 (shown in Fig. 6). The lamp socket 110 is preferably a conventionaledison screw light socket, into which a suitable light source 142 such as aLED bulb may be attached.

The base 102 further comprises a lamp shade support structure 114.The lamp shade support structure 114 may be formed as a cylindrical shelf-like protrusion around the circumference of the lamp socket 110. The lampshade support structure 114 is configured to vertically support the lamp shade104 and form a base which provides a desired orientation of the lamp shade104 and of the sound reflecting plate 106.

The lamp shade 104, shown in Fig. 4, comprises a support structure130 which is intended to be oriented such that it abuts directly or indirectlyagainst the lamp shade support structure 114 of the base 102.

The base 102 may be provided with a cover, for instance made from afabric material that is permeable for air such that sound from the loudspeaker108 can be effectively transmitted therethrough.

Sound is, as mentioned, emitted from the loudspeaker 108 of the base102 and is spread in a horizontal direction and in a vertical direction to acertain degree, which among other things depends on the frequency of thesound and on the shape, size and distribution of apertures in the base 108through which the sound is emitted. However, when the lamp shade 104 isarranged on the base 102, some of the sound emitted by the loudspeaker 108could potentially end up being dampened or in other ways affected by thelampshade 104. The sound reflecting plate 106 is configured to reflect thesound emitted from the loudspeaker 108 in the base 102 such that as littlesound as possible becomes affected by the lamp shade 104.

The sound reﬂecting plate 106 is shown in a top view in Fig. 3a and ina bottom view in Fig. 3b.

The sound reflecting plate 106 is preferably horizontally arranged, i.e.perpendicularly to a central axis A of the loudspeaker lamp unit 100, on top ofthe base 102. The sound reflecting plate 106 could however be arranged atan angle in relation to the central axis A that is not perpendicular, for instanceto allow a greater vertical spread of the sound emitted from the base 102.

The sound reflecting plate 106 may be provided with a shape thatessentially corresponds to the shape of the base 102. ln the embodimentshown in Figures 2-3b, the base 102 is cylindrically shaped with a circularcross-section with varying diameter with varying height. The sound reflectingplate 106 is accordingly provided with a symmetrical circular shape.

Other shapes are however considered for the sound reflecting plate106, such as for instance rectangular, elliptical or oval to name a few.

The sound reflecting plate 106 may also be non-symmetrically shaped.For instance, the base 102 may be provided with a loudspeaker(s) 108 that isconfigured to emit sound in certain direction. ln such an embodiment, thesound reﬂecting plate 106 may be shaped such that it forms a circularsegment having an angular extension corresponding to the horizontal anglewith which the sound is emitted from the base 102. For example, if sound isemitted from the base 102 with a horizontal distribution angle of a maximumof 180°, the sound reﬂecting plate 106 may be formed by a circular segmenthaving a horizontal angle approximately 180°. This may be beneficial to savematerial as there is no need for reflection of sound on the other half of thebase 102. Similar arrangements are of course possible even in embodimentsin which the sound reﬂecting plate 106 is not round.

The sound reﬂecting plate 106 preferably comprises a through hole118 through which the lamp socket 110 is insertable. The through hole 118thus has a diameter corresponding to or slightly larger than the diameter ofthe outer diameter of the lamp socket 110. The through hole 118 may furtherbe slight smaller than the diameter of the lamp socket 110 to provdide apress-fit connection between the sound reflecting plate 106 and the base 102.

The sound reflecting plate 106 may have a radial extension in relationto a central axis A from a bottom 116 of the base 102 to the top 112 of thebase 102, shown in Figs 2-3b, that is essentially equal to or larger than aradial extension of the base 102 in relation to the central axis A. The centralaxis A is defined as a central axis A through each of the components of theloudspeaker lamp unit 100. The sound reflecting plate 106 having a radialextension, i.e. a radius from the central axis A, equal to or larger than theradius of the base 102 allows most of the sound emitted from the base 102 tobe reflected away from the lamp shade 104 by the sound reflecting plate 106.

Preferably, the sound reflecting plate 106 has a radial extension inrelation to the central axis A that is less than a radial extension of the lampshade 104 in relation to the central axis A. lt is generally not preferred that thesound reflecting plate 106 extends radially beyond the lamp shade 104, as itmay result in an undesired aesthetic appearance to the loudspeaker lamp unit100.

The sound reflecting plate 106 is preferably formed from a plasticmaterial such as PET (Polyethylene terephthalate) or PMMA (Poly methylmethacrylate acrylic, acrylic glass, or plexiglass). Other materials are howeveralso considered, such as glass, metals or composite materials. The soundreflecting plate 106 preferably has a thickness of 1 mm to 3 mm, preferably 2mm.

The sound reflecting plate 106 may be made from a material that is toa certain degree permeable for light, i.e. not opaque. The sound reflectingplate 106 will thus affect the light emitted from the light source 142 to a lesserdegree. The sound reflecting plate 106 may be configured to disperse lightemitted from the light source 142, for instance by being provided with astructured top surface 122 and/or a structured bottom surface 126 of thesound reﬂecting plate 106.

The sound reflecting plate 106 may comprise a top dampening layer120 on the top surface 122 thereof and a bottom dampening layer 124 on thebottom surface 126 thereof, as is shown in Figures 3a and 3b respectively.The dampening layers 120, 124 are more elastic and softer than the rest ofthe sound reflecting plate 106, thus reducing the risk of undesired vibrations from the Ioudspeaker 108 of the base 102 giving rise to noices formingbetween the sound reflecting plate 106 and adjacent components of theIoudspeaker lamp unit 100. The top and bottom dampening layers 120, 124thus functions as anti-vibration gaskets for the sound reflecting plate 106.

The top and bottom dampening layers 120, 124 are preferably formedfrom EVA (ethylene-vinyl acetate), which provides suitable materialproperties. However, other similar materials could also be used as is realizedby one skilled in the art.

The top and bottom dampening layers 120, 124 may be separatelyformed from the sound reflecting plate 106 and attached thereto by means ofan adhesive or by a bonding operating such as thermal bonding. The top andbottom dampening layers 120, 124 may be formed by tape and be attached tothe sound reflecting tape 106 by means of an adhesive.

The top and bottom dampening layers 120, 124 may further beintegrally formed with the sound reflecting plate 106.

The top and bottom dampening layers 120, 124 are configured to abutagainst components of the Ioudspeaker lamp unit 100 adjacent to the soundreflecting plate 106. The top dampening layer 120 and/or the bottomdampening layer 124 should cover a respective area on the top surface 122and the bottom surface 126 respectively that is smaller than a total surfacearea of the top surface 122 and of the bottom surface 126 respectively toavoid dampening sound emitted by the Ioudspeaker 108. Preferably, the topand bottom dampening layers 120, 124 have a respective width W1, W2which essentially corresponds to the respective contact surfaces of thecomponents of the Ioudspeaker lamp unit 100 which abuts against the soundreflecting plate 106, such that the top and bottom dampening layers 120, 124are covered by the adjacent components abutting against the sound reflectingplate 106. ln Figure 4, the lamp shade 104 is seen in a top view. The lamp shade104 may as shown comprise a support structure 130 which is arranged toabut the bottom dampening layer 124. The support structure 130 may beannularly formed, thus comprising a central hole 140. A frame associated withthe support structure 130 may be provided, the frame supporting the material 11 of the lamp shade 104, e.g. a fabric shade 144 or similar, in a conventionalmanner. The support structure 130 is preferably arranged such that it abutsagainst the lamp shade support structure 114 (see Fig, 2). ln one embodiment, the sound reflecting plate 106 is attached to thesupport structure 130 by means of an adhesive such as tape or glue. Thesound reﬂecting plate 106 and the lamp shade 104 could thus be considereda unit, faciltating assembly of the loudspeaker lamp unit 100. Preferably, thesound reﬂecting plate 106 is attached such that the bottom dampening layer124 thereof is attached to the contact surface 132 of the support structure 130of the lamp shade 104. The sound reflecting plate 106 is thus attached to theupwards facing side of the support structure 130. lt is however also possiblethat the sound reflecting plate 106 is attached to the downwards facing side ofthe support structure 130, such that the upper dampening layer 120 of thesound reﬂecting plate 106 is attached to the support structure 130 of the lampshade 104. The contact surface 132 may thus be the oppositely facingsurface of that shown in Figure 4. ln Figure 5 is a locking member 128 shown. The locking member 128may be configured to be threaded onto the lamp socket 110, to an externalthread thereof (not shown). The locking member 128 may thus form a nutwhich holds the lamp shade 104 and the sound reflecting plate 106 in placeagainst the base 102. The locking member 128 is arranged to abut the topdampening layer 120 of the sound reflecting plate 106.

With reference to Figs 3 to 5, the top dampening layer 120 has a widthW1 in a radial direction of the sound reflecting plate 106 in relation to thecentral axis A. The width W1 should preferably correspond to a width W4 of acontact surface 134 of the locking member 128. The top dampening layer 120will thus not extend radially past the contact surface 134 of the lockingmember 128 and thus not dampen sound emitted by the loudspeaker 108 ofthe base 102.

The bottom dampening layer 124 has a width W2 in a radial directionthat corresponds to a width W3 of a contact surface 132 of the supportstructure 130 of the lamp shade 104. 12 The respective contact surfaces 132, 134 of the Iocking member 128and the support structure 130 are to be considered as the portion of theIocking member 128 and the support structure 130 of the lamp shade 104respectively that is configured to be in contact with the sound reflecting plate106, or more specifically with the top and bottom dampening layers 120, 124thereof.

Turning now to Figures 6 and 7 which disc|oses an exploded view of aIoudspeaker lamp unit 100 and to a schematic flowchart of a method 1000 forassembling a Ioudspeaker lamp unit 100 respectively.

The base 102 is firstly provided onto which the support structure 130of the lamp shade 104 is arranged 1001. The support structure 130 isarranged 1001 on the lamp shade support structure 114 of the base 102.

The sound reﬂecting plate 106 is arranged to the top 112 of the base102. lt is to be realized that the sound reflecting plate 106 can be arranged1002 directly against the lamp shade support structure 114 ofthe base 102.The support structure 130 of the lamp shade 104 may then be arranged 1001on top of the sound reflecting plate 106.

The sound reﬂecting plate 106 is arranged 1002 around the lampsocket 110 with the lamp socket 110 arranged in the through hole 118 of thesound reﬂecting plate 106.

The sound reﬂecting plate 106 and the lamp shade 104 can then belocked 1003 to the base 102 by means of the Iocking member 128. Thesound reﬂecting plate 106 and the lamp shade 104 are thus firmly securedand held in their respective desired position in relation to the base 102. ln one embodiment, the sound reflecting plate 106 is attached to thesupport structure 130 of the lamp shade 104 by means of an adhesive prior toarranging 1002 the sound reflecting plate 106 to the top 112 of the base 102.The sound reflecting plate 106 can thus be provided with the lamp shade 104as a unit which faciltates assembly of the Ioudspeaker lamp unit 100. Theadhesive may be an adhesive tape and/or a glue. Preferably, as mentioned,the sound reflecting plate 106 is attached with the bottom dampening layer124 facing the contact surface 132 of the support structure 130 of the lamp 13 shade 104. ln other words, such that the sound reﬂecting plate 106 isarranged on top of the support structure 130 of the lamp shade 104.

A suitable light source 142, such as a LED-light source, maysubsequently be attached to the lamp socket 110.

Consequently is a loudspeaker lamp unit 100 provided in which theeffect of the lamp shade 104 on the sound emitted from the base 102 isreduced. The sound reflecting plate 106 effectively reflects sound transmittedby the loudspeaker 108 of the base 102 that would otherwise be dampenedor interferred by interaction with the lamp shade 104. The base 102 thuseffectively becomes acoustically isolated from the lamp shade 104, whichthus allows replacing the lamp shade 104 without affecting the performanceof the loudspeaker 108.

As evident from the above, the sound reflecting plate 106 may in orderto reduce cost and complexity be dimensioned to fit with standard dimensionsof adjacent components of the loudspeaker lamp unit 100. For instance, thelamp socket 110 may be provided with different dimensions depending on thetype of light bulb thread (e.g. E14, E27 etc) that it is intended for. This appliesaccordingly to the lamp shade support structure 114, to the support structure130 of the lamp shade 104 and to the locking member 128 which may all beprovided with standard dimensions corresponding to the size of the lampsocket 110 and the sound reflecting plate 106 may be dimensionedaccordingly. The sound reflecting plate 106 may thus be provided also toexisting loudspeaker lamp units. lt will be appreciated that the present invention is not limited to theembodiments shown. Several modifications and variations are thusconceivable within the scope of the invention which thus is exclusively definedby the appended claims.
