Japanese Patent JP2931762
Kind Code:
B2
Abstract:
An electronic keyboard instrument for reproducing reflected sound generated by an acoustic piano and providing the feeling that sound is reflected and shifted. Left and right system sound signals are generated corresponding to the position of a depressed key on a keyboard. The sound signals are processed through a digital signal processor, a digital-to-analog converter and amplifiers. The processed sound signals are transmitted to left and right loudspeakers. The digital sound processor is composed of filters for extracting predetermined frequency components from each of the sound signals, delay elements for transmitting outputs from the filters with a delay of predetermined time, and adders for adding outputs from the delay elements to the original left and right system sound signals.
