Abstract
The invention discloses an audio processing unit, headset, virtual reality equipment, and an audio processing method. The headset comprises the audio processing unit and a head-mounted part. The audio processing unit receives an audio command sent by the head-mounted part, and transmits the audio command to an audio source. The audio source transmits audio data to the audio processing unit according to the audio command. If the audio data is 3D audio data, the audio processing unit carries out the audio algorithm processing of the 3D audio data, and then transmits the 3D audio data to the head-mounted part. If the audio data is 2D audio data, the audio processing unit transmits the 2D audio data to the head-mounted part. Therefore, the head-mounted part can play 3D audio data so as to achieve a 3D surround sound effect, and also can play 2D audio data so as to achieve a 2D stereo sound effect. The headset is used for the virtual reality equipment, and greatly improves the visual virtual reality experience of a user through cooperating with a 3D head-mounted display.
