An electronic cymbal and a bell part sensor installation method are provided. The electronic cymbal includes: a disk-shaped frame; a frame bell part which is configured at a center of the frame in a top view; a bell part sensor which is attached onto the frame bell part in a circumferential direction and detects a hit on the frame bell part; and a cover which covers the frame and the bell part sensor and has a surface formed as a hit surface, wherein the bell part sensor is separated in at least a radial direction of the frame bell part.

An electronic percussion instrument, a stroke detection device, and a stroke detection method which can improve stroke detection accuracy are provided. A thickness dimension (L2) of an upper cover part (5b1) is approximately constant from the inner circumferential side to the outer circumferential side in a region facing the upper surface of an outer circumferential part (4b3) of the frame bow part (4b) (a concave part formed according to a level difference between a bent part (4b2) and the outer circumferential part (4b3)). Accordingly, the entire upper cover part (5b1) is easily deformed such that it is bent when struck, and thus a protrusion part (5b3) can be securely pressed to an edge sensor (7b) according to deformation of the upper cover part (5b1). Therefore, the accuracy of detection of a stroke applied to the upper cover part (5b1) can be improved.

Contact transducer for musical instruments with soundboard, comprising: vibrating element, consisting of an air core coil made of enameled copper wire, suitable to be placed in contact with the soundboard of any musical instrument, and able to vibrate according to said soundboard; magnetic field generator, consisting of a permanent magnet, preferably made of neodymium, suitable to transform the vibrations of the vibrating element induced by the soundboard in electric signals, according to the principle of electromagnetic induction; sound-insulating separator made of elastic material, on which the magnetic field generator is fixed, keeping it firmly and close to the vibrating element, and isolating it from the vibrations of the soundboard; electric cable connected to the ends of the copper wire of the vibrating element with at least one connector suitable to transfer the electrical signal generated to at least one sound amplification device.

An electromagnetic multi-function multi-purpose chordo-phone musical instrument upon which any form or style of music may be played in any position by a performer standing or seated, in a fixed location or moving throughout a performance venue. The player may initiating the vibrations of each string, any combination of strings, or all of the strings with a plectrum or the fingers of one or both hands, singly or in any combination and such vibrations will continue until their eventual natural termination unless damped and/or muted by the player using the fingers or the palm of one or both hands singly or in any combination. The shape and style of the rigid frame of the instrument is not limited by the need for frets, a fretboard, or keys.

A device and method for an amplitude modulated optical pickup for a stringed instrument are disclosed. A first optical source comprising a first output signal comprising a first carrier frequency is provided and a first photodetector is in optical communication with the first optical source. A vibrating element such as a string on a musical instrument is disposed in an optical path between the first optical source and the first photodetector whereby a vibration of the element varies and modulates an amplitude of the first output signal received by the photodetector that is proportional to an element vibration amplitude and is at the same frequency as the element vibration frequency. An amplitude modulated (AM) photodetector signal output is generated from the first photodetector. The resultant signal is then demodulated with appropriate circuitry to produce a substantially noise free electronic signal representative of the element vibration frequency.

An apparatus for selecting between sets of pickups for a stringed musical instrument including a top plate with two sets of pickups embedded therein that is rotationally attached to a back plate. The apparatus includes an electrical connector that enables electrical connection between the pickups and the instrument. The apparatus further includes attachment structure enabling fastening of the instrument to a backside of the instrument. The apparatus is configured to extend through a body of the instrument such that the top plate is adjacent strings of the instrument.

The disclosure seeks to describe a system and method for transmitting acoustic energy to a listener. The system includes a flexible pick-up, at least one acoustic energy transmisson member and at least one audio output. The flexible pick-up has an interior, at least one opening, and is configured for compression against strings of a stringed instrument for direct energizing by the strings. The at least one acoustic energy transmission member has a first end coupled to the interior of the pick-up through the opening. The at least one audio output is mounted on a second end of the energy transmission member and is configured to transmit acoustic energy therefrom to a listener.

An keytar (1) includes a keyboard (2) on which a plurality of keys (2a) are arranged, a ribbon (5) in which a front surface panel (81) is arranged, and the degree of the same type of musical sound effect applied to each of tones (A-D) produced by the key (2a) is changed corresponding to detection positions in an X-direction in the front surface panel (81). Accordingly, because the degrees of the musical sound effects can be respectively changed for each of the tones (A-D) corresponding to the detection positions in the X-direction of the front surface panel (81), for the change of the same type of musical sound effect toward the tones (A-D), the monotony of this change can be suppressed and an expressive performance can be achieved.

This invention refines and expands the use of mode switches in common-point connection circuits for matched pickups on musical instruments. For example, on a 3-coil S-type electric guitar, where the common-point connection circuit with a single-ended output provides three humbucking pair outputs and three humbucking triple outputs, a 4P2T mode switch can ground the common point and provide both all of the standard non-humbucking 5-way switch outputs, as well as adjusting the tone capacitor to make both humbucking and non-humbucking tone outputs more compatible. On an electric guitar with three dual-coil humbuckers, mode switches of one 6P2T, one 2P2T and three 1P2T can choose between dual-coil and single-coil operation modes, humbucking and non-humbucking modes, and partially simulate the effect of flipping single-coil magnets at will, by choosing which coil of each humbucker is used.

A hand-held strumming device includes a hollow body, a power source, a motor, a regulator, and a strummer. The power source is disposed in the hollow body. The motor is in electrical communication with the power source. The regulator is in electrical communication with both the motor and the power source. The regulator is configured to selectively adjust a rotational speed of the motor. The strummer is rotatably disposed on the disk. The strummer is configured to be presented to strings of a stringed instrument upon rotation of the motor to strum the strings.
