Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings.

[0019] Such as figure 1 and figure 2 As shown, the present invention provides a speaker module 100, which includes a casing 1 with a containing space and a speaker unit 2 accommodated in the containing space.

[0020] The speaker unit 2 is an electromagnetic speaker, including a diaphragm 21 and a voice coil (not shown) that drives the diaphragm 21 to vibrate. In the working state, the diaphragm vibrates and pushes the gas to compress to generate sound waves.

[0021] The casing 1 includes a top wall 101 surrounding an accommodation space, a bottom wall 102 and a side wall 103 connecting the top wall 101 and the bottom wall 102 . Further, the speaker module further includes a partition wall 104 for separating the accommodating space to form an incompatibility cavity and a supporting step 105 for fixing the speaker unit 2 .

[0022] The partition wall 104 encloses ...

Abstract

The invention relates to a loudspeaker module. The loudspeaker module comprises a shell and a loudspeaker monomer; the loudspeaker monomer is contained in the shell, and has a vibrating diaphragm; theshell comprises a top wall, a bottom wall and a side wall; the bottom wall is opposite to the top wall; the side wall is connected to the top wall and the bottom wall; the vibrating diaphragm of theloudspeaker monomer is arranged to be just aligned to the bottom wall; the loudspeaker module further comprises support steps; the support steps extend from the inside surface of the shell to the loudspeaker monomer, and fix the loudspeaker monomer; one side of the loudspeaker monomer close to the vibrating diaphragm is arranged on the support steps; furthermore, a monomer containing cavity is divided into a front sound cavity and a rear sound cavity; the front sound cavity is formed among the support steps, the bottom wall and the vibrating diaphragm; the rear sound cavity is formed among theloudspeaker monomer, the side wall, the support steps and the top wall; at least one part of the support steps is opposite to the bottom wall, and arranged at intervals, so that a leakage channel communicated with the front sound cavity is formed; a leakage hole communicated with the leakage channel and the rear sound cavity is arranged on the support steps in a penetrating manner; and a waterproof breathable film is pasted on the leakage hole. Thereby, the waterproof and dustproof properties can be realized while gas leakage and pressure stability are ensured; and the product reliability isimproved.

Description

technical field [0001] The invention relates to the field of electroacoustic conversion, in particular to a loudspeaker module. Background technique [0002] With the advent of the mobile Internet era, electronic products are being updated faster and faster, and people have higher and higher requirements for the performance of electronic products. One of them is the high-quality music function. Therefore, the electroacoustic system It is necessary to continuously improve performance, and a high-quality speaker module is one of the prerequisites for realizing this high-quality music function. [0003] A speaker module in the prior art usually includes a housing and a speaker unit accommodated in the housing, usually by enlarging the acoustic cavity of the speaker module to improve the low frequency response of the product and improve the acoustic performance of the product. In order to achieve leakage, it is usually necessary to set a leakage hole in the enlarged acoustic ca...
