ラウンド装置。[Claims for Utility Model Registration] In a surround device that reproduces and outputs a direct wave of an acoustic signal and a reflected wave delayed by a delay circuit of the direct wave from main speakers and surround speakers arranged in a listening room, A controller that sets the optimum delay time and level of reflected waves for the listening room by the delay circuit by inputting data such as the distance from each speaker, the material of the wall of the listening room, and the room size, and the output of the delay circuit. A surround device comprising: a frequency conversion circuit that converts a high-frequency component of a signal to twice the frequency; and an addition circuit that combines an output signal of the delay circuit and an output signal of the conversion circuit and outputs the synthesized signal to the surround speakers.
