Problems solved by technology

[0002] The motor used in the mobile phone needs to vibrate under the drive of the driving voltage. Since the driving circuit and the motor are connected by wires and the resistance on the wires, the voltage applied to the motor is usually lower than the output voltage of the driving circuit. The motor with ring structure, because the drive circuit will not receive the feedback about the vibration of the motor, it will cause the motor to not be in the optimal vibration state when vibrating

Abstract

The invention discloses a method and a device for controlling motor vibration, and an electronic device. The method comprises: using a gravity sensor to collect the acceleration of gravity of a motor generated during vibration; according to the acceleration of gravity, determining a first driving parameter needed for driving the motor, the type of the first driving parameter being decided by the type of the motor; and controlling the driving circuit to drive the motor with the first driving parameter. According to the technical scheme, a driving circuit with an open loop structure can control the motor in an optimal vibration state. While the circuit structure of the driving circuit is simplified, a stable vibration effect of the motor is still ensured.

Description

technical field [0001] The present disclosure relates to the field of electronic technology, in particular to a method and device for controlling vibration of a motor, and electronic equipment. Background technique [0002] The motor used in the mobile phone needs to vibrate under the drive of the driving voltage. Because the driving circuit and the motor are connected by wires and the resistance on the wires, the voltage applied to the motor is usually lower than the output voltage of the driving circuit. For a motor with a ring structure, since the drive circuit will not receive feedback about the vibration of the motor, the motor will not be in an optimal vibration state when vibrating. Contents of the invention [0003] In order to overcome the problems existing in related technologies, embodiments of the present disclosure provide a method and device for controlling vibration of a motor, and electronic equipment, which can control the motor to be in an optimal vibrati...
