Magnetostrictive lever tuning type self-sensing super-elastic memory alloy wire single-string elastic musical instrument

The invention discloses a magnetostrictive lever tuning type self-sensing super-elastic memory alloy wire single-string elastic musical instrument which is mainly composed of a magnetostrictive actuator, an amplification lever, a string clamp, a mute stepping motor, a playing piece, a musical bow, a crank sliding block mechanism, a super-elastic memory alloy wire string, a string fixing bolt and an ohmmeter. According to the device, musical notes are converted into corresponding electric signals through a control signal generator, the electric signals are amplified by the power amplifier and then a magnetostriction lever is controlled, the tensioning degree of the memory alloy wire strings is adjusted, and the tone is accurately adjusted by combining with the ohmmeter. Meanwhile, the control signal generator transmits a control signal to a stepping motor driver, so that the mute stepping motor drives the playing piece or the music bow to play. According to the device, rapid and accurate automatic tuning of on
