Title:
SPEAKER MODULE
Document Type and Number:
WIPO Patent Application WO/2016/034012
Kind Code:
A1
Abstract:
A speaker module comprising a module housing, which accommodates therein a speaker unit (40). A sound output aperture (12) is located at a side of the speaker unit (40). The speaker unit (40) divides a cavity of the entire module into two cavities, namely a front acoustic cavity (70) and a rear acoustic cavity (72). The front acoustic cavity (70) is in communication with the sound output aperture (12). A piece of acoustic foam (50) is provided within the front acoustic cavity (70). The acoustic foam (50) is fixed on the module housing. Also, the acoustic foam (50) is arranged to avoid a vibration space of a diaphragm (422) of the speaker unit (40). The present solution effectively improves the performance of a sensitivity curve of the module at high frequencies on the basis that no change is required for the cavity structure of the front acoustic cavity (70), thus not only increasing the acoustic performance of the module, but also simplifying the structure of the front acoustic cavity (70) of the module.
