Abstract: A keyboard musical instrument comprises a plurality of juxtaposed movable key units and a plurality of juxtaposed strings, each of which has one end fixed to the corresponding key unit and the other end immovably attached to the body of the key board musical instrument and is vibrated at a prescribed frequency upon operation of the corresponding key unit, wherein each string is prevented from making vibration by a stationary damping member while the corresponding key unit remains inoperative and commences vibrations at a prescribed frequency upon operation of the key unit; and the vibrations are electrically detected by pickup devices and, after amplified, are sent forth through a loud-speaker as a musical tone.

Abstract: The pickup system for a string instrument uses a combination of a single under-string pickup, or a primary pickup, and a secondary offset pickup that is placed away from the strings. The primary pickup senses the vibrations of the strings while also picking up background noise. The secondary pickup does not pick up the vibration of the strings, only picking up the background or environmental noise. Thus, in various combinations, the secondary pickup with the primary pickup can cancel out the background noise. This cancellation occurs without creating any drag beyond that of the primary pickup.

Abstract: A musical instrument adapted for use with a turntable. Said apparatus uses a rotary pulse generator to create musical tones when in contact with the rotating platter of the turntable. Said apparatus mounts to the turntable in such a way that a rotary pulse generator rotates when in contact with the rotating turntable platter. As the radius at which the rotary pulse generator contacts the turntable platter is increased the frequency of the tone produced increases proportionally, likewise when the radius at which the rotary pulse generator contacts the turntable platter is decreased the frequency of the tone produced decreases proportionally allowing a range of pitches to be sounded.

Abstract: The present invention relates to an electronic drum induction structure, and more particularly to a structure eliminating noise generated from a drumhead of an electronic drum so as to transmit electronic induction sound only. The electronic drum induction structure of the present invention is mainly formed by combining an induction ring with a woven net, where the induction ring is an annular foam, inside which an induction sheet is sandwiched, and an induction signal line is connected; the woven net is formed by weaving resin fibers, and an induction ring is attached on the rear face of the woven net at the inner diameter of the circumference thereof.
