Abstract: A self-adaptive control miniature motor comprises a driving unit (200), a mover (300) and a self-adaptive control unit (100). The driving unit comprises a fixed stator and a movable vibration block, and provides the driving force for the reciprocating motion of the mover through the interaction between the stator and the vibration block. The mover is a forced vibration part, and is driven by the movable vibration block of the driving unit to do the reciprocating motion. The self-adaptive control unit is used for controlling a motion state of the mover in real time by adjusting a force applied on the mover, based on a feedback information of the motion state of the mover. The self-adaptive control miniature motor, by combining the motor hardware with a control circuit, facilitates real-time adjustment of the magnetic field intensity in the motor, thus improving the stability of the vibration of the motor.

Abstract: It is disclosed a speaker module, including a module housing, a speaker assembly and a heat-dissipating member. The module housing has an inner cavity, the inner cavity includes a front cavity and a rear cavity spaced apart from the front cavity, and the front cavity is communicated with an external space. The speaker assembly is mounted in the inner cavity, the speaker assembly includes a vibration diaphragm spacing the front cavity and the rear cavity apart. The heat-dissipating member has a heat-conducting section and a heat-dissipating section, the heat-conducting section is in contact with the speaker assembly, the heat-dissipating section stretches into the front cavity. The vibration of the vibration diaphragm allows air in the front cavity to flow to increase the heat-dissipating rate of the heat-dissipating section. The heat-dissipating section may have a heat-dissipating structure for increasing a heat-dissipating area, and the heat-dissipating structure may be a heat-dissipating fin. The speaker module provided by the present invention has a favorable heat dissipation performance, and is capable of duly transferring heat generated by the speaker during operation to the outside of the module.
