Abstract
Main speakers are arranged on the enclosure front surface of an electronic piano. Auxiliary speakers (18L, 18R) are arranged on the rear surface of the enclosure. Microphones are arranged in close proximity of the main speakers. A performance sound is regenerated from the main speakers. The regenerated sound from the main speakers is picked up by microphones (20L, 20R). FIR filters are used to generate the reflected signal of a picked-up sound signal from the microphones. The generated reflected sound signal is regenerated from auxiliary speakers.
