Abstract
Description
Technical Field
[0001] The present application relates to the technical field of sound processing, and in particular to a device for reducing vibration of a loudspeaker. Background Art
[0002] At present, the speakers used in large-screen and soundbar products are all high-power speakers of more than 5W. The speaker modules they form have excessive vibration energy, which causes the entire device to vibrate. In addition, speakers are usually also used in terminal electronic devices such as video conferencing, mobile phones, tablets, and headphones, and are also accompanied by lenses. However, since the voice coil motor (VCM) of the lens is very sensitive to vibration interference, the vibration of the speaker when playing sound can easily cause the lens to shake, resulting in blurred images, out-of-focus problems, etc. Summary of the invention

[0006] According to the first aspect, in a first possible implementation of the first aspect, the first drum-shaped cantilever (10) and the second drum-shaped cantilever (11) are made of elastic materials with a certain damping. The first drum-shaped cantilever (10) and the second drum-shaped cantilever (11) can be made of elastic materials with a certain damping, such as silicone rubber, nitrile rubber, etc., so that the drum-shaped cantilever can be squeezed and deformed with vibration, thereby achieving a shock-absorbing and buffering effect.
[0007] According to the first aspect, in a first possible implementation manner of the first aspect, the first drum-shaped cantilever (10) and the second drum-shaped cantilever (11) are used to generate extrusion deformation during the vibration of the speaker for buffering and shock absorption.
[0008] According to the first aspect, in a first possible implementation of the first aspect, the central through hole (30) is used to limit and support the device. The central through hole is used to penetrate the first drum-shaped cantilever (10) and the second drum-shaped cantilever (11), playing a supporting and connecting role for the structure.
[0009] According to the first aspect, in a first possible implementation manner of the first aspect, the first drum-shaped cantilever (10) is flush with the uppermost end of the central through hole (30). The first drum-shaped cantilever (10) is located at the uppermost end of the structure.
[0010] According to the first aspect, in a first possible implementation manner of the first aspect, the second drum-shaped cantilever (11) is flush with the lowest end of the central through hole (30). The second drum-shaped cantilever (11) is located at the lowest end of the loudspeaker damping structure.
[0011] According to the first aspect, in a first possible implementation of the first aspect, the locking groove (20) is used to be locked with the speaker body. The locking groove (20) is used to be subsequently connected with the speaker body, mainly to be able to be fully locked with the locking position in the speaker body to form a whole.
[0012] According to the first aspect, in a first possible implementation of the first aspect, the first end surface radial ribs (40) and the second end surface radial ribs (41) include a certain number of directional straight ribs. The certain number of directional straight ribs can be defined according to actual needs, and the function of the directional straight ribs is to reduce the contact area and prevent the problem of vibration noise that may be caused by surface-to-surface contact.
[0013] According to the first aspect, in a first possible implementation of the first aspect, the first drum-shaped cantilever (10), the second drum-shaped cantilever (11), the positioning groove (20), the central through hole (30), the first end surface radial rib (40), and the second end surface radial rib (41) are an integral structure made of the same material. Therefore, the speaker shock absorbing device is an integral structure that is axially symmetrical and vertically symmetrical, made of uniform material, and has a hollow center.

[0023] Example
[0024] This embodiment provides a speaker vibration reduction device, such as Figure 1 As shown, Figure 1 The figure shows a speaker damping device 100, which includes a drum-shaped cantilever 10, a locking groove 20, a central through hole 30 and end surface radiating ribs 40. Figure 1 As shown in the front view (a), the speaker shock absorbing device 100 adopts a double drum-shaped rubber ring design. The speaker shock absorbing device 100 as a whole presents an axisymmetric structure. The upper and lower sides of the speaker shock absorbing device 100 are drum-shaped cantilevers 10, and the middle is a positioning groove 20. Figure 1 As shown in (b), the speaker damping device 100 is an overall structure that is axially symmetrical and centrally symmetrical. The center of the device 100 is a hollow structure, that is, a central through hole 30 is opened at the central axis. Figure 1 As shown in (c), radial ribs are left on both side end faces of the drum-shaped cantilever 10, namely, end face radial ribs 40. The shape of the end face radial ribs 40 is straight ribs in 8 directions on the central ring. The number of the straight ribs can be set according to actual needs and is not strictly limited here. The shape design method of the end face radial ribs 40 is used to reduce the contact area between the rubber ring and the guide column to prevent vibration and noise problems that may be caused by surface-to-surface contact.
[0025] In this embodiment, the speaker shock absorbing device 100 adopts a double drum-shaped rubber ring design as a whole. The entire speaker shock absorbing device 100 presents an axially symmetrical structure based on the locking groove 20 in the middle position. The locking groove 20 is a groove part formed between the drum-shaped cantilevers 10 at both ends of the speaker shock absorbing device 100 and the central through hole 30 of the drum-shaped cantilever passing through the two ends. It is mainly used to support the speaker body. The groove part provides the function of ear-hanging limit, which is used to contact with the speaker ear after assembly; located at both ends of the locking groove 20 are drum-shaped cantilevers 10, and the drum-shaped cantilever 10 is a hollow drum-shaped rubber structure, which is the main body that plays a shock absorbing effect. When the speaker vibrates, the hollow drum-shaped cantilever 10 is offset to one side as a whole, and the drum-shaped structure is squeezed and deformed, playing a vibration absorption and buffering role with the same properties as a spring.
[0026] In this embodiment, Figure 1 (d) shows a three-dimensional structure, the speaker damping device 100 includes a rubber ring through hole portion, which is the central through hole 30 in the figure. The central through hole 30 is used to insert the entire speaker damping device 100, and plays a role in limiting and supporting the entire speaker; the speaker damping device 100 is mainly made of rubber material, which can be an elastic material with certain damping such as silicone rubber, nitrile rubber, etc. The speaker damping device 100 can be used in mobile phones, tablet computers, music players, laptop computers, large screens and other devices with speakers, which are not limited here.
[0027] In this embodiment, the speaker shock absorbing device 100 has radial ribs on the end surfaces of both sides of the drum-shaped cantilever 10. The shape is a central ring plus 8 directional straight ribs, which are used to reduce the contact area between the rubber ring and the guide column, prevent vibration and noise problems that may be caused by surface-to-surface contact, and can effectively improve the sound transmission quality and effectively enhance the user experience.
