Voice remote controller and power supply method thereof

Abstract

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.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a voice remote controller and a power supply method thereof. Background technique [0002] As an essential component of the TV, the remote control has been seeking better user experience and technological innovation while increasing its functions in recent years. For the power supply method of the remote control, there are two main methods on the market: [0003] The first power supply method uses button batteries, dry batteries and other non-rechargeable cycle power supply methods. The disadvantages of this power supply method mainly lie in the waste of resources and environmental pollution caused by waste batteries after the battery power is exhausted. [0004] The second power supply method is a rechargeable cycle power supply method using a rechargeable battery such as a lithium battery. The inconvenience of this power supply method is that it needs to be charged frequent...
