Abstract: An embodiment relates to a speaker and a speaker module. The speaker comprises a vibration system and a magnetic circuit system; the vibration system comprises a diaphragm and a voice coil coupled to the diaphragm; a space between a front side of the diaphragm and a front sound cavity cover forms a front sound cavity, and a space between a back side of the diaphragm and a rear sound cavity cover forms a rear sound cavity; wherein the speaker further comprises a plurality of injection molding inserts disposed along a vibration direction of the diaphragm, and the injection molding insert comprises a first end and a second end; the first end is joined with a surface of the front sound cavity cover close to the diaphragm, and the second end is joined with a surface of the rear sound cavity cover close to the diaphragm. One technical problem to be solved by the embodiment of the present invention is to ensure, by using the injection molding inserts, the stability of relative distance and parallelism of the diaphragm connection surface of the housing with respect to both the front sound cavity support surface and the rear sound cavity support surface, so as to ensure stability of the acoustic performance of the speaker.

Abstract: A vibrating motor and an electronic device are disclosed. The vibrating motor comprises a housing formed by an upper housing and a lower housing. A slider portion and a stator portion are accommodated in a cavity enclosed by the housing. The slider portion comprises magnets, spring sheets and a mass block. The mass block has accommodating grooves matching the external contour of the magnets, and the magnets are accommodated in the accommodating grooves. The mass block is connected to the upper housing via the spring sheets, and is suspended inside the housing. The stator portion comprises coils and a basin frame that is made of a magnetic material The basin frame is fixed on the lower housing, and has accommodating structures matching the external contour of the coils. The coils are embedded in the accommodating structures of the basin frame.
