Control method used for sound in virtual reality environment and system thereof

The invention relates to a control method used for a sound in a virtual reality environment and a system thereof. The system is characterized by comprising an MCU central processing unit, a wireless communication module, a power supply module, an audio amplifying circuit module and an audio output module, wherein the MCU central processing unit is respectively connected with the wireless communication module, the power supply module and the audio amplifying circuit module, and the audio amplifying circuit module is connected with the audio output module. According to the invention, distance between a user and each virtual sound source is determined by virtue of audio information, acquired by the MCU central processing unit, in the virtual reality environment, positional information of movement of the user in the virtual reality environment, positional information of a sound source in the virtual reality environment and position and direction information of the movement of the user, the audio power amplificati
