The present invention discloses a speaker module, comprising: a speaker assembly, a module shell and a front cover. The module shell is configured to bear the speaker assembly, and comprises a first shell and a second shell, wherein the first shell is doped with a thermally conductive filler. The front cover is configured to cooperate with the module shell to encapsulate the speaker assembly. The speaker module provided by the present invention can quickly discharge heat generated by the speaker assembly during operation through the module shell to prevent overheat of the speaker assembly, thereby avoiding performance loss of a speaker due to high temperature.

The present disclosure relates to a magnetic circuit assembly of a bone conduction speaker. The magnetic circuit assembly may generate a first magnetic field. The magnetic circuit assembly may include a first magnetic element, and the first magnetic element may generate a second magnetic field. The magnetic circuit may further include a first magnetic guide element and at least one second magnetic element. The at least one second magnetic element may be configured to surround the first magnetic element and a magnetic gap may be configured between the second magnetic element and the first magnetic element. A magnetic field strength of the first magnetic field within the magnetic gap may exceed a magnetic field strength of the second magnetic field within the magnetic gap.

Voice coil actuators and loudspeakers containing same. The voice coil actuators include moving voice coil assemblies that have multiple segments. Each segment of a moving voice coil assembly is separately controlled by an amplifier, one channel of an amplifier, and combinations thereof utilized in combination with a position sensor that senses the position of the moving voice coil assembly. By this arrangement, the voice coil actuators produce a linear force per unit current throughout the range of motion while obtaining the benefits and advantages associated with both over-hung and under-hung voice coil actuator designs.

Disclosed in the present disclosure are a sound production apparatus and an electronic device. The sound production apparatus comprises a holder, a vibration unit, an elastic member, and a damping member, wherein the elastic member connects the holder and the vibration unit, and the damping member is disposed on the elastic member. The technical solution of the present disclosure aims at preventing the elastic member from resonating with the vibration unit, thereby ensuring the vibration trajectory of the vibration unit, and ensuring the operation stability of the sound production apparatus.
