てなる請求項１記載のサラウンド回路。[Scope of claims for utility model registration] (1) 4 left channel L, right channel R, center channel C, and surround channel S
a surround decoder that encodes one channel into two channels and decodes the transmitted audio signal into the original four channels; and an L signal, R signal, and S signal from the surround decoder and any plurality of the four channels. A headphone including at least a bass headphone is connected to a speaker terminal for respectively deriving the low-frequency components of the mixed signal, and a signal obtained by arbitrarily mixing a plurality of the L signal, R signal, S signal, and the four channels is connected. a surround circuit comprising a headphone terminal for respectively deriving low-frequency components of the speaker terminal, the frequency band of the low-frequency component supplied to the speaker terminal and the low-frequency component supplied to the headphone terminal being different from each other. surround circuit. (2) The low-frequency component of a signal that is a mixture of the L signal, R signal, and C signal is output to the speaker terminal, and the low-frequency component of a signal that is a mixture of the L signal, R signal, and S signal is output to the headphone terminal. 2. The surround circuit according to claim 1, wherein the components are derived.
