Definitions

  • the present invention relates to an attachment system according to the preamble of claim 1 for a mobile phone or the like portable communication means for temporarily attaching it to a belt, the dashboard of a car or the like supporting surface.
  • the attachment system comprises an attachment member fastened to the casing of the portable communication means, and a holder on the supporting surface to which said attachment member can be locked.
  • Portable telephones are nowadays used to an ever increasing extent in the noise of the traffic and other noisy places where the audibility often constitutes a problem.
  • the loud speaker of the mobile phone is usually visible as small openings in the casing of the phone. The sound coming from those openings gets easily lost in the noise of the surroundings. It is however not desirable to add earphones to the telephone, as this should be kept as light and small as possible.
  • the mobile phone and its casing should be made as "streamlined" as possible without any unnecessary members protruding from the casing.
  • the attachment system according to the invention is mainly characterized by the features defined in the characterizing part of claim 1.
  • a number of arrangements of various designs are possible. It is in many prior attachment systems possible to dispose the attachment member at the loud speaker and arrange the structural parts of the attachment member in form of a rim so that an opening of the same size as the area formed by the loudspeaker openings is formed inside the rim for leading the sound to the ear.
  • the attachment members arranged in form of a rim prevent the noise from reaching the ear.
  • An opening can, on the other hand, easily be arranged in the middle of the attachment member in some attachment systems. The modifications required can often be made without the attaching capacity of the attachment member being changed.
  • the member forming the rim comprises - a cylindrical part, the first end of which is fastened to the casing of the communication means and the inner diameter of which is larger than the diameter of the area provided with openings formed by the openings of the loud speaker on the surface of the casing, and - an actual annular locking member formed at the rim of the second end of the cylindrical part, by means of which the attaching member can be locked to the holder.
  • the inner diameter of the annular locking member is substantially of the same size as the inner diameter of the cylindrical part, and the outer diameter is larger than the outer diameter of the cylindrical part.
  • the annular locking member preferably forms a mainly convex surface against the ear, whereby it feels pleasant when it is held against the ear.
  • the attachment member is typically fastened to the phone on its front side. If the loud speaker openings are situated on the back side of the phone, the attachment is of course fastened on this side.
  • FIG. 2 is a schematic cross sectional view of attachment member according to the invention disposed on the casing at the location of the loud speaker openings;
  • FIG. 3 is a similar view as FIG. 2 of a second embodiment of the invention.
  • FIG. 4 is a similar view as FIG. 2 of a third embodiment of the invention.
  • FIG. 1 shows a phone 10, to the casing 12 of which an attachment member 14 according to the invention is fastened.
  • the attachment member is disposed on the casing 12 at the location of the sound openings 16 of the loud speaker.
  • the attachment member 14 is rim-shaped and positioned on the casing 12 in the way that the openings 16 are in the centre of the attachment member.
  • the attachment member thus does not essentially cover the openings.
  • the inner diameter H of the attachment member is typically somewhat larger than the mean diameter h of the area of the casing covered by the openings. Typically H is in the order of 1.2 to 1.5 h.
  • the size of the inner diameter, and sometimes also the shape, of the part of the attachment member which is against the casing naturally depend essentially on the area formed by the loud speaker openings.
  • the diameter of the area provided with openings is typically about 5 to 7 mm.
  • FIG. 2 shows a cross section of the phone casing 12 taken across the openings 16.
  • the attachment member 14 which is shown in an axial cross section comprises a cylindrical base part 18 which is fastened to the casing 12 at its first end 20.
  • Locking members 24 by means of which the attachment member 14 is locked to the holder (not shown) are disposed on the second end 22 of the base part 18.
  • the locking member 24 is an annular member, the inner diameter H of which is of the same size as the inner diameter of the base part 18.
  • the outer diameter H 2 is considerably larger than the outer diameter of the cylindrical base part.
  • the outer surface 26 of the annular part which is to be put against the ear is convex.
  • the size k of the annular part 24 is preferably such as to fit into the outer ear in front of the ear channel .
  • the outer dimension of the annular part is typically about 8 to 15 mm, most typically about 10 to 13 mm.
  • the total height of the cylindrical base part 18 and the annular part 24 is typically about 5 to 10 mm, most typically about 6 to 8 mm. The dimensions can naturally vary depending on the various types of phones .
  • FIG. 3 shows an attachment member 14 of another type, which is mainly shaped as a truncated cone.
  • the end 30 having the smaller diameter is fastened by means of a flange 32 to the casing 12 of the phone.
  • the end 34 of the cone having the larger diameter protrudes from the casing and the protruding surface is in this case flat but could also be convex or of some other shape fitting into the ear.
  • FIG. 4 shows a third attachment member 14, which is formed of a first cylindrical base part 18 and a second cylindrical part 36 having an inner diameter of the same size as the first part but a larger outer diameter and disposed on the protruding end thereof.
  • the base part 18 is fastened to the phone casing 12 by means of a flange 32.
  • the loud speaker openings are positioned at the inner channel 28.
  • the attachment system according to the invention provides thus with simple means an earphone-like construction at the loud speaker openings, which prevents noise and assists in carrying sounds from the phone to the ear.
  • no parts protruding from the casing of the phone are needed, besides the attachment member. It is thus according to the invention possible to a great extent to utilize parts already existing in the casing.
  • the invention can be modified in many ways and it is not restricted to the embodiments described above.
  • the annular and cylindrical members do not have to be exactly annular or cylindrical, but can be of angular or irregular shape and be composed of different parts to form a rim around the loud speaker openings of the phone.
  • a member like the attachment member can naturally be used in front of the loud speaker openings for improving the audibility even if the member would not constitute a part of any attachment system.
