Speaker module and electronic device using the same

Abstract

The invention discloses a speaker module which comprises a speaker single body and an outskirt frame containing and fixing the speaker single body. The speaker single body comprises a vibrating film. A sound outlet is arranged in a position, directly opposite to the vibrating film, of the outskirt frame. A rear sound cavity is enclosed by the speaker single body and the outskirt frame. An opened end which communicates the rear sound cavity and the outside is arranged in an end face of one side, corresponding to the rear sound cavity, of the outskirt frame. The electronic device of a terminal is combined with the opened end to seal the rear sound cavity. The invention discloses an electronic device, a combination plate is included in the electronic device. The combination plate and the opened end of the speaker module is combined to seal the rear sound cavity. A space of the speaker module is fully used with such a structure. Under the condition that the size of the speaker module is limited, a space of the rear sound cavity of the speaker is enlarged, the acoustic performance of the speaker module is ensured and an internal structure of the electronic device is fully used.

Description

technical field [0001] The invention relates to the field of electroacoustics, in particular to a loudspeaker module and an electronic device using the loudspeaker module. Background technique [0002] In the prior art, the speaker module includes a speaker unit and a peripheral frame for accommodating and fixing the speaker unit. For a speaker module that emits sound from the front, the sound outlet is arranged on the side of the peripheral frame facing the diaphragm of the speaker unit. The speaker module has a rear acoustic cavity, which is formed by the speaker unit and the peripheral frame on the side of the diaphragm away from the sound outlet. The rear acoustic cavity of the speaker module needs to be sealed and has a certain volume to ensure the low frequency of the speaker module. sound effects. [0003] However, with the development trend of thinner electronic devices (such as mobile phones, computers, etc.), the space reserved for the speaker module in the electr...

AI Technical Summary

Problems solved by technology

When the size of the speaker module is small, on the one hand, it may affect the size of the speaker unit, thereby affecting the acoustic performance and output power of the product; on the other hand, the volume of the sound cavity behind the speaker module will decrease, which affects the speaker module The low-frequency sound effect of the group, affecting its acoustic performance

On the other hand, the traditional structural loudspeaker module and the electronic device only realize simple installation and electrical connection, and the internal structure of the electronic device is not fully utilized.
