WIPO Patent Application WO/2017/197895
Kind Code:
A1
Abstract:
Disclosed in the present invention are a sound absorbing assembly for a speaker module, and a speaker module. The sound absorbing assembly comprises a supporting housing, an accommodating groove is disposed in the supporting housing, and a sound absorbing material is filled in the accommodating groove; the supporting housing is fixed in a rear sound cavity of the speaker module by means of injection molding; sound through holes are disposed on the bottom the accommodating groove, and the interior of the accommodating groove is communicated with the rear sound cavity by means of the sound through holes. The sound absorbing assembly according to the present invention is provided with an accommodating groove on the supporting housing, and a sound passage is formed by means of the sound through holes of the accommodating groove, so that the sound absorbing material disposed in the accommodating groove functions to absorb sound, thereby improving the sound quality of the speaker. The supporting housing features thin walls and is high-strength, which is conducive to saving space of the sound cavity and improving the sound quality of the product. In addition, the supporting housing is fixed in the rear sound cavity of the speaker module by means of overall injection molding, so that the injection molding yield rate is higher than that of an injection mesh cloth, and the requirements for injection process are lower, which may save costs and facilitate batch production.
