<p>The circuit for generating the 1st surround sound which is phase- locked to the original sound and the 2nd surround sound which is out of phase by using the switching controller and the channel sound delayer includes a surround mode selector (160) for filtering the 1st and the 2nd channel surround signals (ALS) (ARS), a surround out-status controller (180) for delaying the ALS and ARS, and applying them to speakers (SSPL)(SSPR), and buffers (19)(23) for filtering several control signals and applying them to control the selector of the surround mode (160) and the non-surround mode (180) controllers.</p> |
