Title:

ROTARY VIBRATION MOTOR

Document Type and Number:

WIPO Patent Application WO/2021/134494

Kind Code:

A1

Abstract:

The utility model provides a rotary vibration motor. The motor comprises a housing, a transmission rod fixed in the housing, a vibrator rotatably connected around the transmission rod, a driving coil fixed to the housing and spaced apart from the vibrator, and a return device fixed at both ends of the transmission rod. The vibrator comprises a counterweight sleeved on the transmission rod, and a driving magnet fixed to the counterweight. The transmission rod is threadedly connected to the counterweight. The driving coil surrounds the transmission rod and interacts with the driving magnet to drive the vibrator to vibrate along the axial direction of the transmission rod and rotate with respect to the transmission rod. Thus, the vibration mode of the motor is more diverse, and the vibration feeling is stronger and richer.
