Abstract

The invention discloses a motor driving circuit, a motor driving method and electronic equipment. The motor driving circuit comprises a drive module, a booster module, a signal input end and a signal output end, wherein the signal input end and the signal output end are connected with the drive module; the booster module is electrically connected with a power supply unit; the drive module comprises a digital-to-analogue conversion unit and an amplifying unit; the digital-to-analogue conversion unit is used for receiving a digital audio signal through the signal input end and converting the digital audio signal into an analogue signal; the amplifying unit is used for amplifying the analogue signal and transmitting the amplified analogue signal to a motor through the signal output end; the booster module is used for boosting input voltage provided by the power supply unit and outputting the boosted input voltage to the amplifying unit. Therefore, driving voltage output by the motor driving circuit can be increased, the start and stop time of the corresponding motor is shortened and the transient performance of the motor can be developed.

Description

technical field [0001] The invention relates to the technical field of motor driving, in particular to a motor driving circuit, method and electronic equipment. Background technique [0002] At present, the industry often uses a drive motor drive circuit based on a push-pull circuit to drive the motors in various electronic devices. The drive voltage output by the motor drive circuit in this way is small, which may lead to a small vibration of the corresponding motor. The problem of weak vibration feeling and long start and stop time also makes it difficult to achieve diverse vibration effects. [0003] That is to say, the existing motor driving circuit has the problems of providing a relatively small driving voltage and failing to exert the transient performance of the motor. Contents of the invention [0004] Embodiments of the present invention provide a motor driving circuit, method and electronic equipment, which are used to solve the problems of the existing motor d...
