Abstract

The invention relates to a vibration device and a control method thereof, electronic equipment and a storage medium. The vibration device comprises a motor, a photoelectric transceiving assembly and acontrol circuit; the motor comprises a vibrator and a fixed part, and the vibrator can move relative to the fixed part; the photoelectric transceiving assembly is connected to the fixing part, and isused for emitting detection light and receiving the detection light reflected by the oscillator; and the control circuit is connected with the photoelectric transceiving assembly and is used for detecting the time interval between the time when the photoelectric transceiving assembly emits the detection light and the time when the photoelectric transceiving assembly receives the detection light and controlling the motion state of the vibrator according to the time interval, so that the vibration detection and control precision of the motor vibrator is improved.

Description

technical field [0001] The present disclosure relates to the technical field of electronic equipment, and in particular, to a vibration device and a control method thereof, electronic equipment, and a storage medium. Background technique [0002] In electronic devices, interactive feedback through vibration is often required. At present, a motor is usually installed under the screen to realize screen vibration. The vibration state of the screen is controlled by the motion state of the motor. Therefore, in order to control the vibration state of the screen, it is often necessary to detect the motion state of the motor. [0003] At present, the position of the linear vibration motor is mainly detected by setting a Hall element in the motor, and the movement of the mass block of the motor is controlled by the position of the linear motor. However, the detection of the motor position through the Hall element is easily affected by the magnetic field, which makes the detection e...
