Kind Code:
A1
Abstract:
The embodiments of the present application relate to a method and a device for sounding by means of a motor, an electronic variator and an unmanned aerial vehicle, said method comprising: a motor controller controlling a motor driver to apply a pulse voltage to at least one phase winding of a motor, so as to cause the rotor of the motor to vibrate and cause the motor to play a piece of music, the piece of music being composed of a plurality of different sounds, each of the sounds being generated by applying, in at least one phase winding of the motor, a pulse voltage including at least two frequencies, the frequencies of the pulse voltages respectively being 1 /T1,..., 1/TN, where N is a natural number and N≥2. In the embodiments of the present application, a motor driver is controlled to apply, into at least one phase winding of the motor, a pulse voltage including at least two frequencies, so as to cause the rotor of the motor to vibrate and cause the motor to make a sound, and the motor makes a plurality of different sounds to form a piece of rich-toned music with more pleasant sounds.
