摘要

A drive apparatus and heat dissipating apparatus for a vibrating diaphragm coil of a speaker, a mobile terminal and heat dissipating method, the heat dissipating apparatus includes: a control unit configured to output an enabling signal to trigger an audible sound drive circuit to work when judging the speaker is in a sounding state, and output an enabling signal to trigger an non-audible sound drive circuit to work if the speaker is in a non-sounding state; the audible sound drive circuit configured to, after being enabled by the control unit, amplify a received audio signal, then drive the vibrating diaphragm coil of the speaker to vibrate; and the non-audible sound drive circuit configured to, after being enabled by the control unit, drive the vibrating diaphragm coil of the speaker to vibrate and control the vibration frequency of the vibrating diaphragm coil to be human ear non-audible ultrasonic or infrasonic frequency. The drive apparatus, the heat dissipating apparatus, the mobile terminal and the heat dissipating method provided by the embodiments of the present invention, can increase the air convection and heat exchange and reduce the complete machine temperature to achieve the purpose of heat dissipation by controlling vibration of the speaker vibrating diaphragm.
