A percussion instrument motion reproduction device includes a percussion instrument. The percussion instrument includes a vibration portion. The percussion instrument motion reproduction device includes a first driving portion. The first driving portion of the percussion instrument motion reproduction device is configured to visually displace the vibration portion in response to an electrical signal.

A percussion instrument driving device includes an actuator and an actuator mount. The actuator includes an actuator surface configured to vibrate in response to an electrical signal to vibrate a vibration surface of a percussion instrument from outside of the percussion instrument. The actuator mount is disposed outside the percussion instrument having a vibration surface. The actuator mount is configured to mount the actuator to the percussion instrument from outside of the percussion instrument, with the actuator surface facing the vibration surface and spaced from the vibration surface.

A sound apparatus includes a piezoelectric device, a vibration member connected to the piezoelectric device, a first magnet connected to the piezoelectric device, and a second magnet facing the first magnet, which can readily realize a desired frequency characteristic.

An electronic percussion instrument and a method of detecting a percussion position are provided. The percussion position in a left-right direction is calculated by comparing an added-up value of output values of a first edge sensor with an added-up value of output values of a second edge sensor. Compared with a case where peak values of the first and second edge sensors are used, it is possible to make a great difference between an added-up value in a case where the vicinity of the first edge sensor (the second edge sensor) is percussed and an added-up value in a case where a position away from the first edge sensor (the second edge sensor) is percussed.

The present invention provides a sounding control system capable of performing high-accuracy crosstalk suppression while reducing the processing load on a sound source device. When a first pad (12) vibrates, the first pad (12) generates sound emission data (62a1) that is information instructing a sound source device (11) to produce a sound and crosstalk cancellation determination data (62a2) that is information used for canceling crosstalk, and sends the data to the sound source device (11). The sound source device (11) determines whether or not crosstalk has occurred and controls sound emission using the information.

Electric, Electro Acoustic or Acoustic Drum with Internal Wiring Harness is disclosed herein. The drum comprises an internal wiring harness configuration. The internal wiring harness configuration comprises a plurality of first audio jacks that are mounted on an internal surface of the drum. The internal wiring harness configuration further comprises a connector assembly configuration comprising a plurality of second audio jacks and a multi-pin connector mounted on an external surface of the bass drum. Such configuration eliminates long cables and cumbersome wiring and provides a more natural and desirable connection to external processing.

Provision of a piezoelectric element which uses a lightweight and flexible electret material and an electrode layer which is also lightweight, has high conductivity and good flexibility to easily receive electrical signals from an electret, and has good durability. Additionally, provision of a musical instrument provided with such a piezoelectric element. A piezoelectric element comprising an electrode layer (B) on at least one surface of an electret material (A) having pores inside, wherein a porosity of the electret material (A) is 20 to 80%, the electrode layer (B) contains 20 to 70 mass % of a carbon fine particle, and a thickness of the electrode layer (B) is 2 to 100 μm.

An impact detection device includes: a body configured to be struck; a vibration sensor that detects vibration of the body; a support base that supports the vibration sensor; a first elastic body sandwiched between the vibration sensor and the body; and a second elastic body sandwiched between the vibration sensor and the support base. A dimension of each of the first elastic body and the second elastic body is smaller than a dimension of the vibration sensor when viewed from an arrangement direction in which the first elastic body, the vibration sensor, and the second elastic body are arranged.

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.
