[0029] Ginseng See attached Figure 1 To Attachment Figure 5 As shown, attached Figure 1 is a stereogram of an embodiment of a loudspeaker according to the present invention; Figure 2 FIG. 4 is a cross-sectional view of a shock absorbing structure in an embodiment of a loudspeaker according to the present invention; FIG. Figure 3 FIG. 2 is a cross-sectional view of a vibration-absorbing structure in a preferred embodiment of a loudspeaker according to the present invention; FIG. Figure 4 FIG. 1 is a schematic diagram of the structure of the through hole in the embodiment of the speaker of the present invention; FIG. Figure 5 It is a structural schematic diagram of the shock-absorbing structure in an embodiment of the speaker of the present invention; this embodiment discloses a speaker, which is mainly used in a notebook computer.

[0030] The speaker includes a sound-emitting unit and a sound guide cavity 1, a shock-absorbing structure arranged near the sound guide cavity 1, and the shock-absorbing structure includes 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 to the sound guide cavity 1. When the volume is too loud, the vibration in the sound guide cavity 1 will be transmitted to the shock-absorbing structure, and the vibration will be transferred to the metal ball 3 through the elastic unit 2. Because the amplitude and frequency of the vibrating metal ball 3 are different from those of the speaker, the vibration of the speaker is effectively reduced, and the resonance between the speaker and the noise is avoided.

[0031] The elastic unit 2 includes a tubular body 21, and the body 21 may have the same or similar inner diameter from top to bottom. The interior of the body 21 is hollow to form a housing chamber for accommodating the metal ball 3. The inner diameter here refers to the inner diameter. Preferably, the elastic unit 2 includes at least one connecting portion extending outward. In a preferred embodiment, the elastic unit 2 includes a body 21 and at least one connecting portion extending outward from the body 21. The elastic unit 2 is connected to the speaker via the connecting portion.

[0032] The sound guide cavity 1 is arranged around the elastic unit 2, or the elastic unit 2 is circumferentially surrounded by the sound guide cavity 1. The vibration in the sound guide cavity 1 is transmitted to the shock absorbing 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, and the metal ball 3 is stuck inside the body 21. When vibration occurs, the metal ball 3 rubs against the inner wall of the body 21 to reduce the vibration.

[0033] Specifically, the connection part includes a first connection surface 22 and a second connection surface 23 respectively arranged at both ends of the body 21, the first connection surface 22 is connected to the upper surface 11 of the sound guide cavity 1, and the second connection surface 23 is connected to the lower surface 12 of the sound guide cavity 1. When the volume is too loud, the vibration in the sound guide cavity 1 is transmitted to the first connection surface 22 and the second connection surface 23 through the upper surface 11 and the lower surface 12 of the sound guide cavity 1, and then the vibration is transmitted from the first connection surface 22 and the second connection surface 23 to the body 21, and the body 21 transmits the vibration to the metal ball 3, and the metal ball 3 vibrates and rubs against the inner wall of the elastic unit 2. Because the amplitude and frequency of the vibrating metal ball are different from those of the speaker, the vibration of the speaker is effectively reduced, and the resonance between the speaker and the noise is avoided.

[0034] The sound guide cavity 1 includes a side surface 13 close to the elastic unit 2, and a predetermined gap is provided between the side surface 13 and the elastic unit 2. Vibration will not be transmitted from the side surface 13 to the elastic unit 2, and the shock absorbing effect of the metal ball 3 will not be affected.

[0035] 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 is in contact 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 introduction slope 41.

[0036] One end of the elastic unit 2 is provided with an opening 24, and the metal ball 3 enters the interior of the elastic unit 2 from the upper opening 24. In order to facilitate the installation of the metal ball 3, the opening 24 has a second introduction slope 241. In this embodiment, the material of the metal ball 3 is preferably a steel ball, and the material of the elastic unit 2 is preferably rubber.

[0037] See attached Figure 6 , attached Figure 6 The figure is a principle diagram of the sound damping effect according to the present invention. When the speaker emits a forward sound wave, the metal ball 3 will generate a reverse amplitude, and when the speaker emits a reverse sound wave, the metal ball 3 will generate a forward amplitude. The two amplitudes are constantly superimposed to offset the vibration of the speaker. 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. Ideally, the amplitude of the resonance system can be close to zero, and finally the speaker can provide a clear and loud sound.

[0038] It should be understood that the embodiments described herein should be considered in a descriptive sense only and not for the purpose of limitation. The description of the 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 detail may be made therein without departing from the spirit and scope defined by the appended claims.
