Acoustic components and speaker modules for speaker modules

Abstract

The invention discloses a sound-absorbing component for a speaker module and a speaker module. The sound-absorbing component includes a support shell, which is provided with a placement groove filled with sound-absorbing materials, the support shell is fixed in the rear acoustic cavity of the speaker module by injection molding, and the bottom of the placement groove is provided with a sound hole, and the placement groove The interior communicates with the rear acoustic cavity through the sound hole. The sound-absorbing assembly of the present invention is provided with a placement groove on the support shell, and a sound transmission channel is formed through the sound-through hole of the placement groove, so that the sound-absorbing material placed in the placement groove can play a sound-absorbing function and improve the sound quality of the speaker. The wall of the support shell is thin and strong, which can save the space of the acoustic cavity and help to improve the sound quality of the product, and the support shell is integrally injection-molded and fixed in the rear acoustic cavity of the speaker module. Lower requirements can save costs and facilitate mass production.

Description

technical field [0001] The invention relates to the technical field of loudspeaker modules, in particular to a sound-absorbing component and a loudspeaker module for the loudspeaker module. Background technique [0002] In recent years, the market has higher and higher performance requirements for speaker modules, and more and more applications of sound-absorbing particles. In the prior art, when sound-absorbing particles are used in the speaker module, a small cavity is mostly designed in the rear acoustic cavity in the speaker shell, and the small cavity is filled with sound-absorbing particles, and the sound is passed through the small cavity through integral molding technology. The mesh is injected into the hole to form a sealing device, the small cavity is connected with the sound cavity through the mesh, and the sound-absorbing particles play a sound-absorbing role. [0003] In this design, in order to ensure that the mesh can be firmly injected on the small cavity, t...

AI Technical Summary

Problems solved by technology

[0003] In this design, in order to ensure that the mesh can be firmly injected on the small cavity, the wall thickness of the small cavity must be designed to be thick enough to support the mesh, but this will reduce the space of the acoustic cavity and reduce the sound quality

Moreover, with this method, the injection molding yield is low, and the requirements for the injection molding machine are high, which will lead to an increase in production costs.
