A speaker module and an electronic device are disclosed, comprises a module casing, a speaker unit and a linear motor module. The module casing is provided with a mounting cavity; the speaker unit is provided in the mounting cavity and comprises a magnetic circuit system provided with a mounting groove; the linear motor module is provided in the mounting cavity and comprises a housing, a coil and a vibrating assembly; the housing comprises a body part and a protrusion protruding outward; the body part is at a bottom of the magnetic circuit system; the protrusion extends into the mounting groove; the coil is provided in the protrusion part; the vibrating assembly is provided in the body part. The overall structure of the speaker module may be more compact, the speaker unit and the linear motor module may be controlled independently which improves the use effect of the speaker module.

Speaker module and electronic device

Provided in the present disclosure is a diaphragm, comprising a diaphragm body, wherein the diaphragm body comprises a fixing portion at an outer side, a bendable ring portion provided protruding from an inner ring side of the fixing portion and elastically bendable, and an inner side portion at an inner ring side of the bendable ring portion, the diaphragm body is made of a waterproof and breathable material having waterproof and breathable micropores. According to the present disclosure, the diaphragm body is made of waterproof and breathable material having waterproof and breathable micropores so that the diaphragm body has micropores, and the sizes of the micropores are between the size of water molecules and the size of air molecules, such that air molecules can smoothly pass through the diaphragm, while the water molecules can be effectively prevented from passing therethrough.

Diaphragm and loudspeaker

Disclosed is a sound producing device and an electronic product, the sound producing device including a front cover and a shell which are bonded together; wherein a diaphragm is accommodated in a cavity enclosed by the front cover and shell, an upper surface of the front cover away from the diaphragm is covered with an elastic sealing piece, and the elastic sealing piece and the front cover are bonded by hot pressing.

Sound producing device and electronic product

Disclosed is a speaker device, comprising a vibration system, a magnetic circuit system, and an auxiliary system for accommodating and fixing the vibration system and the magnetic circuit system. The vibration system comprises a diaphragm, the auxiliary system comprises a front cover, a side of the front cover is provided a waterproof pad, said side being away from the vibration system. The diaphragm are bonded to the front cover and the waterproof pad by integrally injection molding. The speaker device of the present invention satisfies terminal waterproof requirements for IPX7 and above, and has a good waterproof effect. Besides, a production process of the waterproof speaker device is simplified, production efficiency is increased, production costs of the speaker device are decreased, and the reprocessed product yield of the speaker device is increased.

Speaker device

A speaker device comprises a vibration system, a magnetic circuit system, and an auxiliary system for accommodating and fixing the magnetic circuit system and the vibration system. The vibration system comprises a diaphragm, a centering disk and a voice coil which are joined together. The centering disk comprises a first fixing portion, a second fixing portion provided within the first fixing portion, and a connecting arm connecting the first fixing portion and the second fixing portion. A central position of the second fixing portion is provided with a piezoelectric sheet, the centering disk is provided with a first pad corresponding to the piezoelectric sheet, and the piezoelectric sheet is electrically connected to the first pad. Since a signal emitted by the piezoelectric sheet is mixed with an audio signal emitted by the voice coil-diaphragm, the speaker device of the present invention has improved medium-high frequency effect and acoustic performance.
