Voice remote control apparatus and power supply method thereof

A voice remote controller, comprising:

• a noise gathering module for gathering ambient noise at the periphery of the voice remote controller by using a sound aperture array;
• a sound-electricity converting module for converting the ambient noise gathered by the noise gathering module into an electrical signal;
• and
• an energy storing module for storing the electrical signal converted by the sound-electricity converting module as electric energy and supplying power to the voice remote controller;
• an audio gathering module for gathering a voice signal of the user by using a microphone sound aperture when a voice function of the voice remote controller is turned on;
• and
• an audio processing module for capturing a noise waveform from the ambient noise gathered by the noise gathering module, and superimposing the noise waveform after its phase is inverted onto the voice signal gathered by the audio gathering module to filter out the ambient noise in the voice signal, and further calculates sound pressure of the ambient noise gathered by the sound aperture array and sound pressure of the ambient noise contained in the voice signal gathered by the microphone sound aperture, and sends them to a micro-controlling module of the voice remote controller, when the voice function of the voice remote controller is turned on;
• the micro-controlling module controls the electrical control switches of all sound apertures of the sound aperture array to open when the voice function of the voice remote controller is turned off, and controls the electrical control switches of part of the sound apertures of the sound aperture array to close according to the sound pressure of the ambient noise gathered by the sound aperture array and the sound pressure of the ambient noise contained in the voice signal gathered by the microphone sound aperture, when the voice function of the voice remote controller is turned on;
• wherein the sound aperture array is provided on a main body of the voice remote controller, each sound aperture of the sound aperture array is controlled by an electrical control switch, and a micro-controlling module of the voice remote controller controls turning on or turning off of the electrical control switch of each sound aperture to control the range within which the sound aperture array gathers the ambient noise.
