Abstract

The invention discloses a motor control device of an intelligent terminal and an intelligent terminal. The motor control device comprises a processor and a motor circuit. The processor is electricallyconnected with the motor circuit. The processor is used for controlling the motor circuit to drive a motor to vibrate. The motor control device further includes a switch circuit. The switch circuit is electrically connected with the processor. The motor circuit is electrically connected with the motor through the switch circuit. The processor is further used for generating a switch control signal. The switch control signal is used for controlling the on/off of the switch circuit. When the switch control signal is high in level, the switch circuit is in an on state, and when the switch controlsignal is low in level, the switch circuit is in an off state. According to the invention, by only adding the switch circuit and combining the switch control signal to control the on and off of the switch circuit, the intermittent driving of the motor is realized, the problem that the long vibration or the constant voltage vibration of the motor consumes a lot of electric energy is well solved, the circuit is simple, the cost is low, the power consumption is low and the size is small, and the requirements of the intelligent terminal can be well met.

Description

technical field [0001] The invention relates to the field of motor control, in particular to a motor control device of an intelligent terminal and an intelligent terminal. Background technique [0002] The motor vibration of smart terminals on the market mostly adopts the long vibration or constant voltage vibration mode. In the long vibration mode, the motor will continue to vibrate and consume more power. In the constant voltage vibration mode, the motor rotor will generate strong vibration and consume current. Obviously, it also consumes more power and has low efficiency. Therefore, these two vibration modes affect the battery life of the smart terminal. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to overcome the defect in the prior art that the internal motor of the intelligent terminal generally vibrates with a long vibration or a constant pressure, such vibration consumes a lot of electric energy and affects the en...
