Abstract

The embodiment of the invention provides a loudspeaker module. The loudspeaker module comprises a shell and a loudspeaker unit; the cavity in the shell is separated into a front sound cavity and a rear sound cavity by the loudspeaker unit; a non-closed first colloid is formed around the loudspeaker unit; the shell is provided with a gluing hole corresponding to the opening of the first colloid; asecond colloid is coated in the gluing hole; and the second colloid is formed around the loudspeaker unit, and communicated with the first colloid, so that a sealing part for sealing the rear sound cavity is formed. By means of the technical scheme in the embodiment of the invention, the size of the loudspeaker module can be reduced while the waterproof sealing property is ensured; and thus, design requirements of electronic equipment are satisfied.

Description

technical field [0001] The invention belongs to the technical field of electroacoustic conversion devices, and in particular, the invention relates to a loudspeaker module. Background technique [0002] A speaker is a device that converts electrical energy into sound energy, and is widely used in electronic devices such as mobile phones and computers. [0003] The speaker module usually includes a casing and a speaker unit, and the speaker unit divides the cavity in the casing into a front sound cavity and a rear sound cavity. In the prior art, in order to ensure the waterproof and airtightness of the speaker module, it is necessary to reserve a certain width of glue-coating space inside the shell and around the speaker unit, and realize the complete sealing of the rear acoustic cavity through the glue in the glue-coating space. To prevent water from entering the rear acoustic chamber. However, existing electronic devices are getting lighter and thinner, and the design spa...
