The loudspeaker module solves the technical problems that a housing of the existing loudspeaker module easily burns and melts, and easily generates a resonance sound, enabling the loudspeaker module to dissipate heat rapidly, and accordingly, the housing does not easily burn and melt, and has a long service life. Moreover, the loudspeaker module has a good anti-resonance effect, will not generate a resonance sound, and emits sound with high quality. In addition, the process is simple and easy to realize.
