PURPOSE:To provide an acoustic device with stable acoustic feeling and to prevent it from being a hindrance by providing a control means which outputs stereo signals from plural speakers and a sound source mounted on a carpet main body to one of the plural speakers by mixing an L-channel signal with an R-channel signal. CONSTITUTION:When the sound of the sound source 1 is listened in an ordinary state, no mixture of the L-channel signal 2-L and the R-channel signal 2-R of the stereo signal occurs by turning off them by a switch 51 for mixture in the control means 5. Also, muting switches 53a-53d which turn off the input signals of amplifiers 54a-54d outputted to the speakers 4a-4d are turned off, and amplified L-channel signals are outputted from the speakers 4a, 4b, and amplified R-channel signals from the speakers 4c, 4d. When only the output of the speaker 4d is issued, the muting switches 53a-53c are turned on, thereby, the switch 51 for mixture interlocked with them is turned on, and a signal in which the L-channel signal and the R-channel signal are mixed can be outputted only from the speaker 4d. |
