Claims

[Claims for Utility Model Registration] (1) L-channel and R-channel into which the audio signals of the L-channel and R-channel are input, respectively
- A front speaker for the L-channel, surround speakers for the L-channel and R-channel, and first and second delay circuits that delay the L-channel audio signal by different times and input it to the L-channel surround speaker. and third and fourth delay circuits that delay the R-channel audio signal by different times and input it to the R-channel surround speaker, and a delay of at least one of the first and second delay circuits. the output audio signal of the circuit by a predetermined amount;
The output audio signal of at least one of the first crossfeed circuit and the third and fourth delay circuits is input to the fourth delay circuit by a predetermined amount.
An audio device comprising a second crossfeed circuit that inputs input to a second delay circuit. (2) Utility model registration claim No. 1, which is characterized in that a speaker is provided in the center of the front side and a synthesis circuit that synthesizes an L-channel audio signal and an R-channel audio signal and inputs the synthesized signal to the speaker. Audio equipment described in paragraph (1).
