Voice coil actuator and sensing driver module

A sensing driver module, including:

• a voice coil actuator, having:
• a body base;
• a cover body, connected to the body base to form a receiving space;
• a magnetic element, arranged within the receiving space;
• a rotor assembly, arranged within the receiving space, having a rotor, a first elastic member and a pressing element, the rotor being arranged opposite to the magnetic element and having a hole and a first side, the pressing element being arranged in the hole and having a first end and a second end which is opposite to the first end, the first end being curved and protruding beyond the hole, the first elastic element being arranged on the first side and having a third end and a fourth end which is opposite to the third end, the third end abutting against the magnetic element, the fourth end being located within the hole and abutting against the second end;
• and
• a coil, annularly arranged around a circumference of the magnetic element and connected to the rotor;
• an accelerometer, tightly fitted into the voice coil actuator, the accelerometer for measuring an axial vibration and outputting a vibration signal;
• wherein the voice coil actuator controls the rotor assembly to move according to the vibration signal so as to counter the axial vibration.
