Title: HOLOGRAPHIC STEREO SOUND SYSTEM
Abstract:
A holographic stereo sound system, comprising: a multi-channel sound signal generation system (401), a first multi-channel audio power amplification system (402), a recording and storage system (403), an m-channel pre-amplifier (404), a second multi-channel audio power amplification system (405) and a multi-channel holographic stereo player (406), wherein the multi-channel sound signal generation system (401) generates an m-channel sound electrical signal; the first multi-channel audio power amplification system (402) receives and amplifies a multi-channel sound electrical signal generated by the multi-channel sound signal generation system (401); the recording and storage system is connected to the first multi-channel audio power amplification system (402) and stores the amplified m-channel sound electrical signal; the m-channel pre-amplifier (404) is connected to the recording and storage system (403) and amplifies the amplified m-channel sound electrical signal; the second multi-channel audio power amplification system (405) receives and amplifies the multi-channel sound electrical signal amplified by the m-channel pre-amplifier; and the multi-channel holographic stereo player (406) is connected to the second multi-channel audio power amplification system (405), and plays sound according to the m-channel sound electrical signal. Thus, the multi-point omnidirectional reproduction of a physical holographic stereo sound field can be realized.
