Loudspeaker module and electronic device comprising the loudspeaker module

Abstract

The invention discloses a loudspeaker module. The loudspeaker module comprises a single loudspeaker body and a module housing, wherein a front vocal cavity and a rear vocal cavity are formed between the module housing and the signal loudspeaker body, and the upper ends and the lower ends of the front vocal cavity and the rear vocal cavity are of open structures; and the upper end surface and the lower end surface of the module housing are combined with the element of a terminal electronic device in a sealing manner through a sealing spring washer to enable the upper end surfaces and the lower end surfaces of the font vocal cavity and the rear vocal cavity to be sealed. The invention further discloses an electronic device. The upper surface and the lower surface of the module housing are respectively combined with the circuit board or the device housing of the electronic device in a sealing manner, and the module housing, the circuit board and the device housing are combined in a sealing manner through a sealing spring washer. Such a structure fully utilizes the space of the loudspeaker module and the electronic device, increases the internal space of the loudspeaker module, increases the dimension of the single loudspeaker body and the dimensions of the vocal cavities, and accordingly improves the acoustical performance of a product.

Description

technical field [0001] The invention relates to the technical field of electroacoustic products, in particular to a loudspeaker module and an electronic device including 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 the defect that the speaker unit is directly installed in the electronic device, such as the front sound cavity and the rear sound cavity cannot be completely separated, usually the speaker unit is pre-set in a peripheral frame to fo...

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, so the size of the speaker unit and the size of the sound cavity are also greatly restricted, which affects 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.
