Document Type and Number:
WIPO Patent Application WO/2022/006936
Kind Code:
A1
Abstract:
The present application provides a loudspeaker module. The loudspeaker module comprises: a support; a cover body, covering the support and defining a cavity body with the support in an enclosing manner; an air-permeable isolation member, which is accommodated in the cavity body; and a sound production unit, which is accommodated in the cavity body. The cavity body is divided into an accommodating cavity and a sound absorption cavity by means of the air-permeable isolation member, the air-permeable isolation member covers the sound production unit and defines the accommodating cavity with the support in an enclosing manner, a supporting rib extending towards the air-permeable isolation member in a protruding manner is arranged on a side of the sound production unit close to the air-permeable isolation member, and the air-permeable isolation member abuts against the supporting rib. The cavity body is divided into the accommodating cavity and the sound absorption cavity by means of the air-permeable isolation member, the sound production unit is placed in the accommodating cavity, the supporting rib is arranged on the sound production unit, and the air-permeable isolation member abuts against the supporting rib; and by means of the supporting rib supporting the air-permeable isolation member, the air-permeable isolation member can be prevented from being attached to the surface of the sound production unit due to deformation, such that a situation whereby the acoustic performance of the loudspeaker module is affected due to the deformation of the air-permeable isolation member can be avoided.
