Title:
SPEAKER BOX
Document Type and Number:
WIPO Patent Application WO/2021/000155
Kind Code:
A1
Abstract:
Provided is a speaker box. The speaker box comprises an upper housing, a lower housing combined with the upper housing to form an accommodation space, and a sound emission unit accommodated inside the accommodation space. The sound emission unit divides the accommodation space into a front cavity and a rear cavity. The upper housing comprises a top wall facing the sound emission unit and supporting walls extending from the top wall toward the lower housing. The sound emission unit is fixedly held at the supporting walls and spaced apart from the top wall. The speaker box further comprises a damping mesh provided above the supporting walls and covering the sound emission unit. The damping mesh separates the sound emission unit from the rear cavity. Compared with the prior art, the speaker box of the present invention can effectively mitigate the problem of an excessively large leakage amount of a sound emission unit, thereby improving acoustic performance of the speaker box.
