Loudspeaker module and electronic device using the loudspeaker module

Abstract

The invention discloses a speaker module which comprises an outskirt frame and a speaker single body. A sound outlet is arranged in a side of the outskirt frame. An opened end which communicates the interior of the speaker module and the outside is arranged in the outskirt frame. The opened end is sealed and combined with a combination plate inside the electronic device. The outskirt frame, the combination plate and the speaker single body form a front sound cavity and a rear sound cavity. The front sound cavity and the rear sound cavity are of spaced structures. Meanwhile, the invention discloses an electronic device. The combination plate sealed and combined with the opened end is arranged in the electronic device. With such a structure, a thin speaker module can be ensured and the acoustic performance and output power of the speaker module can be ensured. A space in the electronic device is fully used and achievement of the thin electronic device is benefited.

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] Today, consumers have increasingly thinner requirements for portable electronic devices, and the electronic components inside the electronic devices are also increasingly thinner. Among them, the speaker monomer as an important acoustic component is also becoming thinner. The speaker includes a diaphragm for radiating sound. Since the phase difference of the sound radiated from the front side and the rear side of the diaphragm is 180 degrees, the front cavity and the rear cavity should be spaced structures. In order to avoid defects such as the inability of the front cavity and the rear cavity to be completely separated from each other when the speaker unit is directly installed in the electronic device, the speaker unit is usually placed in a peripheral frame to form a speak...

AI Technical Summary

Problems solved by technology

[0003] However, due to the thinning of electronic devices, the thickness of the speaker module is also strictly limited, and the size of the speaker unit is also greatly limited, thus affecting the acoustic performance and output power of the speaker module

In addition, between the loudspeaker module of the traditional structure and the electronic device, it is only a simple installation on the position and the realization of the electrical connection, which does not make full use of the space inside the electronic device.
