Provided are a holographic audio device and control method; a microphone unit acquires a three-dimensional sound field signal; an acquired-signal processing module processes the acquired signal and converts same to a digital signal; said digital signal is inputted to a holographic sound field signal processing unit; the holographic sound field signal processing unit processes the sound field signal; the processed signal is source-coded and compressed, then sent to a main machine by means of a network; the main machine sends the signal to the holographic audio device by means of the network; the signal is source-decoded, then inputted to the holographic sound field signal processing unit; the holographic sound field signal processing unit outputs the signal to a playback signal processing module; by means of an audio playback unit, audio is played. |
