Title:
VOICE REMOTE CONTROL APPARATUS AND POWER SUPPLY METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2017/071193
Kind Code:
A1
Abstract:
The present invention discloses a voice remote control apparatus and a power supply method thereof, the voice remote control apparatus comprising: a noise acquisition module, utilizing a sound hole array and acquiring ambient noise at the periphery of a voice remote control apparatus; a sound-electricity conversion module, converting ambient noise acquired by the noise acquisition module to an electrical signal; and an energy storage module, converting the electrical signal converted by the sound-electricity conversion module into electrical energy and storing the same, for supplying power for the voice remote control apparatus. The invention utilizes a sound hole array to acquire ambient noise, and converts the same into electricity for operation energy, avoiding replacing a battery or frequent charging. When a voice function of a voice remote control apparatus is off, all of the acquired ambient noise is converted to electricity, improving an energy utilization rate. By adjusting the number of sound holes of the sound hole array and changing the noise acquisition angle, ambient noise can be separated from a user voice signal, and by inverting a noise waveform and superimposing the same on a voice signal, ambient noise in the voice signal can be filtered out, reducing the negative effects of ambient noise on a voice remote control apparatus.
