Loudspeaker module and electronic equipment

Abstract

The invention relates to the technical field of electronics, and discloses a loudspeaker module and electronic equipment. The loudspeaker module comprises a shell and a loudspeaker unit; the loudspeaker unit is arranged in the inner cavity of the shell and divides the inner cavity into a front sound cavity and a rear sound cavity which are isolated from each other; the shell is provided with a sound outlet hole in an area corresponding to the front sound cavity, and the sound outlet hole is communicated with the front sound cavity. A preset number of communication holes are formed in the area,corresponding to the rear sound cavity, of the shell, and the communication holes are communicated with the rear sound cavity. According to the embodiment of the invention, when the loudspeaker unitmakes a sound; the vibration of the vibrating diaphragm pushes the air in the rear sound cavity to move; therefore, air in the rear sound cavity expands and flows out of the communication hole of therear sound cavity to the external environment of the loudspeaker module. According to the invention, the rear sound cavity is expanded by using the external space, equivalently, the volume of the rearsound cavity is increased, so that the Fo value can be reduced, the SPL value can be improved, and the sound effect is effectively improved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a loudspeaker module and electronic equipment. Background technique [0002] In recent years, users' subjective experience requirements for sound effects have been continuously improved, and they have experienced a transformation process from simple sound-loud sound-good sound experience experience. Since the larger the rear sound cavity of the speaker module, the better the sound effect, so increasing the volume of the rear sound cavity is an effective way to improve the sound effect. [0003] However, with the trend of miniaturization, the thickness of electronic devices such as smartphones and tablets is getting thinner and thinner, resulting in less and less available space for speaker modules in electronic devices such as mobile phones and tablets. Therefore, it is very difficult to increase the volume of the rear sound chamber in the speaker module within the limited a...
