PURPOSE:To easily realize a stereoscopic sound field in which a listener is enveloped by letting the directivity of a sound outputted from a speaker part be almost in the up-direction of the main body. CONSTITUTION:The signals of the sounds from a speaker part 8 arranged at the almost surrounding or inside part of a plane main body 7 such as a carpet, and an amplifier provided at the outside part of the main body 7 are inputted through a signal line 4 to a leading-in part 9. The signal line 4 from the leading-in part 9 to the speaker part 8 is wired at the inside part of the main body 4. And also, the speaker part 8 is fixed so that the directivity of the outputted sound can be almost the up-direction of the main body 7 spread on a floor. Thus, the listener inputs the signal of the sound through the signal line 4 to the leading-in part 9, so that the acoustic device can be always arranged at a constant position regardless of the shape or size of a room where the acoustic device is arranged, and the same sound field can be easily realized. |
