Abstract

The present invention discloses an array speaker device to realize personal 3D audio equipment, which utilizes the positioning of 3D sound based on array signal processing to realize a virtual 3D sound image. The sound signal inputted is positioned in cooperation with the Head-Related Transfer Function (HRTF) based on the listener's position, and multi-rate signal processing is introduced to limit the bandwidth processed, so as to reduce the computation load of system, and avoid distortion. Furthermore, two beam-steering methods which are even easier to realize are provided, which can provide the real-time computation to operate the whole sound field in cooperation with a light, small, convenient array type speaker, thereby constructing a 3D sound field without rotating the speaker.
