Abstract: Disclosed is a linear vibration motor comprising a vibrator and a stator arranged parallel to the vibrator. The vibrator comprises a counterweight block and a vibration block embedded and fixed in the counterweight block. The vibration block comprises at least two permanent magnets. The stator comprises a coil. A magnetic conductive core is arranged in the coil. The adjacent end surfaces of the at least two adjacent permanent magnets form slopes parallel to each other. The slopes form an acute angle with the axis of the magnetic conductive core. The slopes extend obliquely in the direction approaching the corresponding magnetic conductive core. The motor not only ensures the maximization of the sizes of the permanent magnets, but also increases the effective magnetic field intensity between a gap between the adjacent permanent magnets and the magnetic conductive core, thus increasing a driving force driving the vibrator into vibration.

Abstract: Disclosed is a sounder module, which comprises a housing for accommodating a vibration system and a magnetic circuit system. The housing is provided with a sound hole which is formed to deviate from the center position of the vibration system and is higher than the surface of the housing. The vibration system comprises a vibrating diaphragm. A dome is provided at one side of the vibrating diaphragm closer to the sound hole. A pressure regulating part is arranged on the dome. The pressure regulating part is higher than other positions of the dome and projects towards the sound hole. The sounder module in the present invention is capable of balancing asymmetrical sound field distribution of the front acoustic cavity, and locally increasing the sound pressure distribution on the surface of the vibrating diaphragm to balance it with other parts, effectively decreasing system polarization, and reducing harmonic distortion.

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.
