This device for controlling feedback of an electronic percussion instrument includes an acquisition part that acquires a feedback signal of a musical sound of the electronic percussion instrument emitted through an amplifier and a speaker, and a processing circuit that performs uncorrelated processing on the feedback signal on the basis of information indicating a control amount, and outputs a signal after the uncorrelated processing to the amplifier.

By limiting deformation of an upper cover part 41 toward an inner peripheral side through catching between an outer peripheral surface of a bent part 21b and a stopper 46 or by forming an interval between a sensor installation part 21d and the upper cover part 41 to gradually increase from the inner peripheral side toward an outer peripheral side, at the time of being struck from a lateral direction, the upper cover part 41 and the lateral cover part 42 are suppressed from contacting an outer edge of the sensor installation part 21d. Thus, since the protrusion 45 is easily pressed to the edge sensor 5, the sensitivity of the edge sensor 5 with respect to the striking from the lateral direction can be facilitated.

An electric bowed string instrument structure comprises a longitudinally elongated frame (2) having a central recess (8) provided with a bottom (9), a fingerboard (5) anchored to the neck (4), a tailpiece (7) anchored to the rear end portion (6) of the frame (2), a plurality of strings (13) extending between the fingerboard (5) and the tailpiece (7), a bridge (12) adapted to support the strings (13), a pick-up (14) adapted to intercept the vibrations produced by the strings (13) and to be connected to sound amplifying means, a soundboard (11) interlocked in the recess (8) in a transversely offset position with respect to the bottom (9), the soundboard (11) being convex with a convexity facing towards the strings (11), the pick-up (14) being arranged below the soundboard (11).

The present invention provides an electronic percussion melody musical instrument, comprising: a key module including a plurality of keys each arranged to receive a knock from the outside, and a plurality of energy conversion units each configured to sense mechanical energy generated by the knocking of the key and convert the mechanical energy into electrical energy in the form of an electrical signal; a storage unit configured to store sound source data associated with the plurality of keys; an output unit configured to output a sound signal corresponding to the sound source data; and a control unit configured to: receive the electrical signal from the energy conversion unit; acquire the sound source data associated with the electrical signal from the storage unit according to the electrical signal; and control the output unit to output the sound signal corresponding to the sound source data.

An electronic percussion instrument includes a base and a drumhead mounted resiliently on the base so as to be movable relative to the base. A plurality of sensors to detect movement of the drumhead relative to the base are spaced about the drumhead at selected positions to measure displacement of the drumhead relative to the base at said selected positions. At least some of said sensors are adjacent the rim of the drumhead and are responsive to movement of the rim of the drumhead towards and away from the base. The individual sensors respond to the movement at their location and the individual responses of the plurality of sensors are simultaneously measured and compared to determine the location of a hit on the drumhead, the force of the hit, and/or the duration of the hit.

An electronic percussion instrument and sound production control method thereof are provided. In an electronic cymbal, the output of a musical sound is controlled in accordance with the results of detection from a strike sensor when the strike sensor detects a strike on a striking surface. While the musical sound is output, if a user touches the striking surface, an electrostatic capacitance sensor outputs an output value in accordance with the contact condition so that the musical sound is attenuated in accordance with the output value while being output. Therefore, the user can attenuate the musical sound being output in accordance with the contact conditions on the striking surface, thereby silencing the musical sound by way of the action similar to that of the acoustic cymbal choke that is the action of touching the striking surface.

A new and improved Digital Musical Instrument includes a hardware segment that electronically detects the physical inputs of a musicians musical playing style or articulated intent; a Software segment that interprets and formulates the data output from the hardware segment, to be applied to any digitally modulated synthesizer or recording sampler; and an optional expanded method of sampling or digitally recording articulated sounds of acoustic instruments.

An electronic hi-hat 1 has a rod movable up and down with an operation of a player. A top cymbal 2 has a striking surface that can be struck by the player. A bottom cymbal 3 comes into contact with or separates from the top cymbal 2. An optical sensor 7 detects separation dimension between the top cymbal 2 and the bottom cymbal 3. The optical sensor 7 detects separation dimensions of a plurality of areas that are displaced with inclinations of the top cymbal 2 and the bottom cymbal 3 with respect to the rod r. The plurality of areas where the separation dimensions are detected are located on a common circumference of the top cymbal 2 and the bottom cymbal 3 around the rod r as a center.
