AI Technical Summary
Technical Problem
Existing speaker modules are inadequate in terms of waterproofing, especially when swimming or diving, as water can easily enter the speaker through the rear sound outlet and cause damage.
Method used
The design employs a co-directional vibration of the upper and lower diaphragms to reduce internal air pressure changes in the speaker module, eliminates the pressure relief hole, and ensures airtightness through support components and an air pressure balance valve to prevent water from entering.
Benefits of technology
The waterproof performance of the speaker module has been improved, ensuring that it will not be damaged when used underwater and that the sound output is stable.

Abstract
The present application relates to the technical field of terminals, and in particular to a loudspeaker module and a terminal device. The loudspeaker module comprises an upper diaphragm, a lower diaphragm, a support housing, a magnetic circuit assembly, a voice coil assembly, and a support assembly; the upper diaphragm and the lower diaphragm are spaced apart in a first direction, the support housing is connected to the side of the lower diaphragm away from the upper diaphragm, and the support housing has at least one first sound outlet hole; the magnetic circuit assembly and the voice coil assembly are both located between the upper diaphragm and the lower diaphragm, the edge of the side of the magnetic circuit assembly facing the upper diaphragm is sealingly connected to the upper diaphragm, and the edge of the side of the magnetic circuit assembly facing the lower diaphragm is sealingly connected to the lower diaphragm; the voice coil assembly passes through the magnetic circuit assembly to connect the upper diaphragm and the lower diaphragm, so as to drive the upper diaphragm and the lower diaphragm to vibrate in the same direction; the support assembly passes through the support housing and the lower diaphragm and supports the lower diaphragm and the magnetic circuit assembly. The loudspeaker module in the present application has high sealing performance, thereby preventing liquid from entering the space between the upper diaphragm and the lower diaphragm.
