Loudspeaker module and manufacturing method thereof

Abstract

The invention provides a loudspeaker module. The loudspeaker module comprises a module shell, a sound production single body and a breathable isolation assembly. An accommodating cavity, a first mounting position and a second mounting position are arranged in the module shell; the sound production single body is mounted ata first mounting position to divide the accommodating cavity into a front sound cavity and a rear sound cavity, and the rear sound cavity is filled with sound absorption particles; the breathable isolation assembly comprises an isolation frame and a breathable isolation piecemounted on the isolation frame, the isolation frame sleeves one end, located in the rear sound cavity, of the sound production unit and is mounted to the second mounting position, and the breathableisolation piece covers one side, deviating from the front sound cavity, of the sound production unit so as to separate the sound production unit from the sound absorption particles; the sound production single body is bonded with the first installation position through a photosensitive adhesive, and the isolation frame is a light-transmitting isolation frame through which light for curing the photosensitive adhesive can pass. The invention further provides a manufacturing method of the loudspeaker module. According to the invention, the sound production monomer can be ensured to be effectivelyfixed, the isolation frame can be ensured to be assembled in place, and the situation that the isolation frame is jacked up due to over-high photosensitive adhesive coating is avoided.

Description

technical field [0001] The invention relates to the technical field of electroacoustic conversion, in particular to a loudspeaker module and a manufacturing method thereof. Background technique [0002] A speaker module is a commonly used electronic component, mainly used for playing audio signals. The resonance frequency of the speaker module is high, resulting in poor low-frequency acoustic performance, making it difficult to play a rich and rich bass. At present, sound-absorbing particles are usually filled in the rear sound cavity of the speaker module to form a virtual sound cavity, thereby improving the low-frequency acoustic performance of the speaker module. Among them, an isolation frame with an isolation mesh cloth needs to be installed in the rear sound cavity to isolate the sound-emitting unit from the sound-absorbing particles and prevent the sound-absorbing particles from entering the sound-emitting unit. [0003] In the related technology, the photosensitive...
