HEADPHONE CIRCUIT SIMULATING REVERBERATION SIGNALS

摘要

A headphone device comprises a pair of headphones for receiving output signals from various acoustic apparatus. A direct sound signal or an output signal of an acoustic apparatus is applied to a reverberation supply circuit to produce an indirect sound signal which is mixed with the direct sound signal in a ratio of more than 1 : 10 to control the feeling of distance to a sound image existing outside the head. Further, the direct sound signal is added to another channel through an attenuator to control the feeling of the direction of the sound image, whereby a natural listening condition similar to the case of loudspeaker listening is obtained.
