Problems solved by technology

[0002] Existing terminal products such as mobile phones and tablet computers have a high waterproof level, and the overall internal air tightness is good. The air pressure of the rear sound chamber of the speaker module is easily changed due to factors such as the user holding the terminal, resulting The internal position of the speaker module is shifted, which affects the sound quality of the speaker module

Abstract

The invention provides a loudspeaker module which comprises a first shell, a loudspeaker inner core and a waterproof breathable film, the first shell is provided with a containing groove, the loudspeaker inner core is installed in the containing groove, the loudspeaker inner core comprises a voice diaphragm, a front voice cavity is formed between the voice diaphragm and the first shell, and the side, away from the front voice cavity, of the voice diaphragm is a rear voice cavity. The first shell is further provided with a resonance groove, the bottom of the resonance groove is provided with a communication hole, the resonance groove is communicated with the front sound cavity through the communication hole, and the waterproof breathable film covers an opening, facing the rear sound cavity, of the resonance groove and is used for isolating the resonance groove from the rear sound cavity so as to balance air pressure of the front sound cavity and the rear sound cavity when the loudspeaker module does not work. The problem that the sound production quality of the loudspeaker module is affected due to the fact that the sound film deviates due to different air pressures of the front sound cavity and the rear sound cavity is avoided, and the sound quality of the loudspeaker module is improved. The invention further provides electronic equipment.

Description

technical field [0001] The present application relates to the technical field of sound generation, and in particular, to a speaker module and an electronic device. Background technique [0002] The existing terminal products such as mobile phones and tablet computers have a high waterproof level, and the overall internal air tightness is relatively good. The position inside the speaker module is shifted, which affects the sound quality of the speaker module. SUMMARY OF THE INVENTION [0003] The purpose of this application is to provide a speaker module and an electronic device for balancing the air pressure of the front and rear sound chambers of the speaker module and improving the sound quality of the speaker module. [0004] The speaker module shown in this application includes a first housing, a speaker core, and a waterproof and breathable membrane. The first housing is provided with an accommodating slot, and the speaker core is installed in the accommodating slot....
