Claims

[Scope of utility model registration request]

An input adder that adds left and right electroacoustic signals, a delay circuit installed after the adder, a level adjustment circuit installed after the delay circuit, and an output signal of the level adjustment circuit for both left and right channels. A sense of spaciousness enlarging device comprising a pair of left and right adders for adding to the left and right electroacoustic signals so that they are in opposite phase between them, and a phase inverter, the device comprising: and a means for changing the delay time of the delay circuit according to the transient nature, and when the transient nature of the input electroacoustic signal is sharp, the delay time of the delay circuit is shortened, and when the transient nature of the input electroacoustic signal is sharp, the delay time of the delay circuit is shortened. When the performance is slow, the delay time of the delay circuit is increased,
A sense of expansion device that is adjustable.
