The invention discloses a voice remote controller and a power supply method thereof. The voice remote controller comprises a noise acquisition module which is used for acquiring environmental noise around the voice remote controller through a sound aperture array, an acoustic-electric conversion module which is used for converting the environmental noise acquired by the noise acquisition module into electrical signals, and an energy storage module which is used for storing the electrical signals converted by the environmental noise through the acoustic-electric conversion module as electrical energy and used for supplying power to the voice remote controller. Through the sound aperture array, the environmental noise is acquired and converted into the electrical energy as a work energy source, so that battery replacement or frequent charging is avoided; when the voice function of the voice remote controller is turned off, the acquired environmental noise is totally converted into the electrical energy, so that the energy utilization ratio is increased; through adjusting the number of opened sound apertures in the sound aperture array, a noise acquisition angle is changed, and the environmental noise is separated from a voice signal of a user, so that a noise waveform can be reversedly superimposed onto the voice signal to filter out the environmental noise in the voice signal, and adverse effects of the environmental noise on the voice remote controller are reduced.

The invention discloses a method of searching a frequency division duplex mobile communication system downlink synchronizing signal. The method comprises steps that S1, a radio frequency power amplifier is adjusted according to a yield value controlled by an automatic gain, and receiving data after the adjustment of the radio frequency power amplifier is cached; S2, whether a downlink synchronizing signal exists in the next downlink synchronizing signal transmitting period is detected: when the downlink synchronizing signal is detected, the position of the downlink synchronizing signal and the yield value controlled by the automatic gain are output, and a searching process is quitted, when the downlink synchronizing signal is not detected, a step S3 is executed; S3, whether a completed searching period number reaches a maximum searching period number is determined: when the completed searching period number reaches the maximum searching period number, the identifications of the unsearched downlink synchronizing signals are output, and the searching process is quitted, and when the completed searching period number does not reach the maximum searching period number, the yield value controlled by the automatic gain is adjusted, and the step S1 is executed. By adopting the method, the amplitude of the synchronizing signal is adjusted in a proper range in a short time, and a searching success rate is improved, and searching time is shortened.
