The present invention relates to the technical field of electro-acoustic products. Disclosed is a speaker module installed in an internal portion of an electronic terminal and comprising a housing. A vibration system and a magnetic circuit system are received in the housing; the magnetic circuit system comprises a bowl-shaped member fixed on the housing; a magnet and a washer are sequentially fixed in the bowl-shaped member; a rear sound-generating hole is provided at a position on a side wall of the housing corresponding to the bowl-shaped member, and is in communication with an inner cavity of the module and an inner cavity of the electronic terminal; and a chamfered surface is provided at an upper end of a side wall of the bowl-shaped member corresponding to the rear sound-generating hole, and is provided at one side of the side wall of the bowl-shaped member adjacent to the rear sound-generating hole. The speaker module solves the technical problems in the prior art of a large volume of the speaker module and the tendency for distortion to occur at a low frequency, thus reducing the volume to the minimum while ensuring an appropriate acoustic performance, satisfying requirements for a light, thin and small electronic terminal, and having high stability and long service life. |
