Electronic stringed instrument.

摘要

An electronic stringed instrument includes strings (15₁ to 15₆), a plurality of metal frets (13₁ to 13₆), an ultrasonic transmitter/receiver (16₁ to 16₆) and a fret discriminator (22). The strings are kept taut above an instrument body (11). The frets (13i) are arranged below the strings (15i) along their extension direction. When a player depresses a given string (15i) to be picked, at least one of the metal frets (13i) is brought into contact with the given string. The transmitter/receiver (16i) is coupled to specified positions of the strings (15i) and causes ultrasonic vibrations of the strings and receives an echo vibration generated as a reflection of the ultrasonic vibration at a fret contacting the given string. The fret discriminator (22) discriminates the fret contacting the string among the metal frets (13i) according to the time difference between the generation of the ultrasonic vibration and the receipt of the echo vibration by the transmitter/receiver (16i).
