Abstract: A loudspeaker module comprises a loudspeaker unit and a module housing. A front acoustic cavity and a rear acoustic cavity are formed between the module housing and the loudspeaker unit. The upper and lower ends of the front acoustic cavity and the rear acoustic cavity are open. The upper and lower end surfaces of the module housing are combined with a terminal electronic device through sealing cushions. An electronic device is also disclosed. The upper and lower surfaces of the module housing are combined with the circuit board or the device housing through sealing cushions. Such a structure fully utilizes the spaces of the loudspeaker module and the electronic device, expands the internal space of the loudspeaker module, increases the sizes of the loudspeaker unit and the sound cavities, and accordingly improves the acoustical performance of the product.

Abstract: Disclosed is an electroacoustic transducer, comprising a vibration system and a magnetic circuit system, wherein the vibration system comprises a vibrating diaphragm and a voice coil; and the magnetic circuit system comprises a yoke, a central magnet, and edge magnets; wherein, each edge magnet has a strip shape, limiting parts are provided at two corners of any edge magnet closer to a magnetic gap, and the yoke is provided with stoppers abutted against the limiting parts at positions corresponding to the limiting parts. Each edge magnet of the present invention is provided with limiting parts formed by removing material, and the yoke is provided thereon with stoppers for preventing the edge magnets from approaching the central magnet, so that a bad phenomenon due to the fact that the edge magnets and the central magnet are attracted to each other can be avoided, thereby increasing the yield of a product.
