Description

Technical Field

[0001] This utility model relates to the field of speaker technology, specifically to a vibration-damping speaker for speakers. Background Technology

[0002] A speaker enclosure is mainly composed of a speaker unit and a cabinet. When a speaker is used, it will generally vibrate. How to deal with the vibration generated by the speaker during operation so as not to interfere with the speaker unit has always been a technical problem that manufacturers need to overcome. There are various vibration reduction methods in the existing technology, but as long as the speaker is assembled with screws or other screws, vibration will occur.

[0003] However, the damping structure used in existing speaker units still has some defects, and some practical functions need to be improved. For example, most of the damping structures used in existing speaker units are just a single damping spring or a single damping foam. Their structural design is relatively simple, and a certain degree of mechanical vibration will still occur inside the speaker when it is running. The damping effect is not good, which affects the sound performance of the speaker unit to a certain extent and also leads to poor sound quality of the sound played by the speaker unit. Utility Model Content

[0004] In order to solve the problems mentioned in the background art, the purpose of this utility model is to provide a vibration-damping speaker for a speaker box. By combining a steel spring ring and a vibration-damping sponge as the vibration-damping structure of the speaker, a better vibration-damping effect can be achieved, while weakening the mechanical vibration phenomenon existing inside the speaker box to a certain extent.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A vibration-damping speaker for a speaker enclosure includes a speaker enclosure, the vibration-damping speaker being fixedly mounted on the speaker enclosure, the vibration-damping speaker including a main fixing bracket, a steel spring ring, a vibration-damping sponge, and a rear housing, the main fixing bracket and the steel spring ring being disposed opposite to each other, the steel spring ring being configured as an annular hollow structure, one side of the main fixing bracket being fixedly connected to one side of the steel spring ring, the other side of the steel spring ring contacting and abutting one side of the vibration-damping sponge, and the side of the vibration-damping sponge contacting the inner side of the rear housing.

[0007] Furthermore, a number of connecting posts are provided on one side of the main fixed bracket, and a connecting screw hole is provided on one side of each connecting post. A connecting screw is provided on one side of the steel spring ring, and the number of connecting posts are fixedly connected to the steel spring ring through the cooperation of the connecting screw hole and the connecting screw.

[0008] Furthermore, the inner side of the rear housing is provided with several connecting protrusions, and the side of the shock-absorbing sponge is provided with several connecting grooves. The shock-absorbing sponge is movably connected to the interior of the rear housing through the cooperation of the connecting grooves and connecting protrusions.

[0009] Furthermore, the vibration-damping horn also includes an external fixing frame, a waveguide diffusion panel, and a sound-producing device. One side of the external fixing frame is fixedly connected to one side of the rear housing. The waveguide diffusion panel is fixedly disposed on one side of the main fixing bracket. The sound-producing device is fixedly clamped between the main fixing bracket and the steel spring ring.

[0010] Furthermore, a first slot and a second slot are provided on one side of the main fixing bracket. A conductive bridging piece is inserted into the first slot and the second slot. One end of the conductive bridging piece is connected to a signal transmission line. One end of the signal transmission line passes through the shock-absorbing sponge and the rear shell in sequence and is connected to the outside.

[0011] Furthermore, the shock-absorbing sponge has a first through hole, the rear housing has a second through hole, and one end of the signal transmission line passes through the first through hole and the second through hole in sequence through the shock-absorbing sponge and the rear housing.

[0012] The beneficial effects of this utility model are as follows:

[0013] (1) One side of the main fixed bracket of this utility model is fixedly connected to one side of the steel spring ring, and the other side of the steel spring ring is in contact with one side of the damping sponge. The side of the damping sponge is in contact with the inner side of the rear shell. When the speaker is running, some of the vibration generated inside will be transmitted to the main fixed bracket. The steel spring ring fixedly connected to the main fixed bracket will reduce this vibration. At the same time, the damping sponge in contact with the steel spring ring will further reduce this vibration. The remaining vibration will be transmitted from the speaker through the rear shell to the damping sponge. The damping sponge will also reduce the remaining vibration. By combining the steel spring ring and the damping sponge as a damping structure, the damping effect of the speaker is achieved, and the mechanical vibration inside the speaker is weakened to a certain extent, thereby ensuring the sound effect of the speaker and optimizing the sound quality of the sound played by the speaker.

Furthermore, the steel spring ring 4 is designed as a ring-shaped hollow structure, which can reduce its own weight, thereby reducing the overall weight of the shock-absorbing horn 2.

[0025] Specifically, the material of the shock-absorbing sponge 5 is polyvinyl alcohol formaldehyde, which has good elasticity and toughness and can effectively absorb and disperse impact force, thereby playing a role in shock absorption.

[0026] Specifically, the interior of the rear housing 6 is provided with a cavity for accommodating the shock-absorbing sponge 5.

[0027] The main fixing bracket 3 of this utility model is provided with several connecting posts 301 on one side. Each connecting post 301 is provided with a connecting screw hole 3011 on one side. A connecting screw 401 is provided on one side of the steel spring ring 4.

[0028] Specifically, the connecting columns 301 are all configured as long column structures. The vibration generated by the speaker 1 during operation is transmitted to the main fixed bracket 3, and then the main fixed bracket 3 transmits it to the steel spring ring 4 through the connecting columns 301. The steel spring ring 4 then performs vibration damping and energy absorption treatment on the generated vibration.

[0032] Specifically, the waveguide diffuser panel 8 can diffuse the sound transmitted by the damping speaker 2, and at the same time, it can make the angle of sound transmission better.

[0033] Specifically, the sound-producing device 9 is the main sound-producing component of the vibration-damping speaker 2.

[0034] The main fixing bracket 3 of this utility model is provided with a first slot 302 and a second slot 303 on one side. A conductive bridging piece 10 is inserted into the first slot 302 and the second slot 303. One end of the conductive bridging piece 10 is connected to a signal transmission line 11.

[0035] The shock-absorbing sponge 5 of this utility model has a first through hole 502, and the rear shell 6 has a second through hole 602. One end of the signal transmission line 11 passes through the shock-absorbing sponge 5 and the rear shell 6 in sequence through the first through hole 502 and the second through hole 602 respectively.

[0036] Reference Appendix Figure 1-7 The working principle of this utility model for a vibration-damping speaker for a speaker box is as follows:

[0037] When the speaker 1 operates and vibrates, some of the vibrations it generates are first transmitted to the main fixed bracket 3. The main fixed bracket 3 then transmits this vibration to the steel spring ring 4 through several connecting columns 301. The steel spring ring 4 absorbs and dampens this vibration. At the same time, the steel spring ring 4 also transmits this vibration to the damping foam 5. The damping foam 5 further absorbs and dampens this vibration by virtue of its elastic properties.

[0038] Vibrations from other parts of the speaker 1 are transmitted to the rear housing 6, and then directly to the damping foam 5. The damping foam 5 also absorbs vibrations from other parts by utilizing its elastic properties. By reducing the amplitude and offset of the vibration of the rear housing 6, the damping effect of the rear housing 6 is achieved, thereby achieving the damping effect of the speaker.

[0039] This invention combines a steel spring ring 4 and a damping sponge 5 as a damping structure to achieve a dual damping effect on the speaker box 1, thereby weakening the mechanical vibration inside the speaker box 1 to a certain extent and effectively ensuring the sound quality of the speaker.

[0040] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
