发明名称 Power operated string vibrating device for selectively vibrating a string of a stringed musical instrument
摘要 A power operated string vibrating device for selectively vibrating a string of a stringed musical instrument having at least one string. The string vibrating device comprises a support member positioned on the musical instrument proximate a string. A first pulley is rotatably mounted on the support member on a first side of a string for receiving a cable. The first pulley has one of the strings associated therewith. A second pulley is rotatably mounted on the support member on a second side of the string for receiving the cable. The second pulley is movable between a first position and a second position. A spring biases the second pulley towards the first position. An endless cable is drivingly interconnected to the pulleys such that when the second pulley is in the first position the cable does not contact the string, and when the second pulley is in the second position the cable contacts the string. An electric motor is mounted on the support member for driving the cable at a predetermined speed. A finger engageable button is mounted on the support member for selectively moving the second pulley to the second position, whereby when the second pulley is in the first position, the string does not produce sound and when the second pulley is in the second position, the string is vibrated by the cable and thereby produces sound.
