Abstract

The invention provides a loudspeaker module. The loudspeaker module comprises a module shell and a single loudspeaker contained in the module shell, wherein the single loudspeaker divides a cavity formed by the module shell into a front acoustic cavity and a rear acoustic cavity; an extending part which extends to the interior of the module shell and is used for supporting and fixing the single loudspeaker is arranged on the module shell, and a sound discharge hole which runs through the front acoustic cavity and the rear acoustic cavity is formed in the extending part; and the sound discharge hole is of a non-circular structure, and a damping element matched with the sound discharge hole in shape is pasted at the sound discharge hole. By utilizing the loudspeaker module provided by the invention, the sound discharge hole can be set to be in a shape adaptive to a narrow and small structure of the module shell, and stable acoustic performance of the loudspeaker module is guaranteed without influencing an overall structure.

Description

technical field [0001] The present invention relates to the technical field of acoustics, and more specifically, to a loudspeaker module. Background technique [0002] With the expansion of the consumer electronics market, a large number of mobile phones and notebook computers are widely used, and as an important acoustic component in consumer electronics products, the sound generating device (or speaker module, the same below) has a wide demand. With the improvement of people's requirements for consumer electronic products, the performance of the sound generating device has also attracted more and more attention. With the requirements of thinner appearance and more excellent performance of consumer electronic products such as mobile phones and tablet computers, the sound generating device, as an important component unit of such products, has also proposed more and more requirements in terms of performance, size and safety. Come higher demands. [0003] The sound generatin...
