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.

Loudspeaker module and electronic device comprising the loudspeaker module

A speaker module includes a casing and a speaker unit housed and fixed in the casing, a rear acoustic cavity being formed between the casing and the speaker unit, wherein at least one baffle wall is provided on the casing in the rear acoustic cavity and divides the rear acoustic cavity into at least two cavities, and wherein at least one slit is formed between the baffle walls or on the baffle wall, so that sound generated by the speaker unit can spread to an adjacent cavity inside the rear acoustic cavity through the slit.
