In the following description, well-known functions or constructions are not described in detail since they would obscure the embodiments with unnecessary detail and the same reference numerals in the drawings represent the same or similar elements throughout the description.
Referring to fig. 1 to 5, fig. 1 is a perspective view of an embodiment of a speaker according to the present invention, fig. 2 is a sectional view of a shock absorbing structure in an embodiment of a speaker according to the present invention, fig. 3 is a sectional view of a shock absorbing structure in a preferred embodiment of a speaker according to the present invention, fig. 4 is a schematic view of a structure at a through hole in an embodiment of a speaker according to the present invention, fig. 5 is a schematic view of a shock absorbing structure in an embodiment of a speaker according to the present invention, and the present embodiment discloses a speaker mainly used in a notebook computer.
The loudspeaker comprises a sound generating unit and a sound guiding cavity body 1, wherein a damping structure is arranged near the sound guiding cavity body 1, the damping structure comprises an elastic unit 2 and a metal ball 3 arranged in the elastic unit 2, and at least part of the elastic unit 2 is connected with the sound guiding cavity body 1. When the volume is too large, the vibration in the sound guide cavity 1 is transmitted to the damping structure, and the vibration is transferred to the metal ball 3 through the elastic unit 2. Because the vibration metal ball 3 has different amplitude and frequency with the loudspeaker, the vibration of the loudspeaker is effectively reduced, and the resonance between the loudspeaker and the noise is avoided.
The elastic unit 2 comprises a tubular body 21, or the body 21 has the same or similar inner diameter from top to bottom, and the interior of the body 21 is hollow to form a containing chamber for containing the metal ball 3. The inner diameter here refers to the diameter of the interior. Preferably, the elastic unit 2 includes at least one connection elastic unit 2 extending to the outside. In the preferred embodiment, the elastic unit 2 comprises a body 21 and at least one connection portion extending to the outside of the body 21. The elastic unit 2 is connected to the speaker through a connection portion.
The sound guiding cavity 1 is arranged around the elastic unit 2, so to speak, the elastic unit 2 is circumferentially arranged around the sound guiding cavity 1, vibration in the sound guiding cavity 1 is transmitted to the damping structure, and the vibration is transferred to the metal ball 3 through the elastic unit 2. The diameter of the metal ball 3 is larger than the inner diameter of the body 21, the metal ball 3 is clamped inside by the body 21, when vibration occurs, friction occurs between the metal ball 3 and the inner wall of the body 21, and vibration is reduced.
Specifically, the connection portion includes a first connection surface 22 and a second connection surface 23 respectively disposed at two ends of the body 21, the first connection surface 22 is connected with the upper surface 11 of the sound guiding cavity 1, and the second connection surface 23 is connected with the lower surface 12 of the sound guiding cavity 1. When the volume is too large, the vibration in the sound guiding cavity 1 is transmitted to the first connecting surface 22 and the second connecting surface 23 through the upper surface 11 and the lower surface 12 of the sound guiding cavity 1, then the vibration is transmitted to the body 21 from the first connecting surface 22 and the second connecting surface 23, the body 21 transmits the vibration to the metal ball 3, the metal ball 3 vibrates, and friction is generated between the metal ball and the inner wall of the elastic unit 2. Because the amplitude and the frequency of the vibrating metal ball are different from those of the loudspeaker, the vibration of the loudspeaker is effectively reduced, and the resonance between the loudspeaker and noise is avoided.
The sound guiding cavity 1 comprises a side 13 adjacent to the resilient unit 2, a predetermined gap being provided between the side 13 and the resilient unit 2. The vibration is not conducted from the side 13 to the elastic unit 2 nor the damping effect of the metal ball 3 is affected.
A through hole 4 is provided in the speaker, and the elastic unit 2 is provided in the speaker through the through hole 4. Of course, it can also be said that the elastic unit 2 is sleeved on the through hole 4, and the elastic unit 2 contacts with the periphery of the through hole 4. In order to facilitate the installation of the elastic unit 2, preferably, at least one end of the through hole 4 is provided with a first lead-in slope 41.
One of the ends of the elastic unit 2 is provided with an opening 24, and the metal ball 3 enters the inside of the elastic unit 2 from the opening 24 at the upper part. To facilitate the installation of the metal ball 3, the opening 24 has a second introduction slope 241. In this embodiment, the metal ball 3 is preferably made of steel balls, and the elastic unit 2 is preferably made of rubber.
Referring to fig. 6, fig. 6 is a schematic diagram of sound damping effect according to the present invention. When the loudspeaker emits forward sound waves, the metal ball 3 can generate reverse amplitude, when the loudspeaker emits reverse sound waves, the metal ball 3 can generate forward amplitude, and the two amplitudes are continuously overlapped to counteract the vibration of the loudspeaker. It can also be said that the amplitude and frequency of the metal ball 3 are different from those of the speaker, and a reaction force can be generated to reduce the vibration of the speaker. In an ideal situation, the amplitude of the resonant system may be close to zero and the resulting loudspeaker may provide a clear and loud sound.
It is to be understood that the embodiments described herein should be considered in descriptive sense only and not for purposes of limitation. The description of features or aspects within each implementation side should generally be considered to be applicable to other similar features or aspects in other embodiments. Although one or more embodiments have been described with reference to the accompanying drawings, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope as defined by the following claims.
