A device is provided for capturing vibrations produced by an object such as a musical instrument such as a drum head of a drum kit. The device comprises a detectable element, such as a ferromagnetic element, such as a metal shim and a sensor spaced apart from and located relative to the musical instrument. The detectable element is located between the sensor and the musical instrument. When the musical instrument vibrates, the sensor remains stationary and the detectable element is vibrated relative to the sensor by the musical instrument.

An apparatus, system, and method for a magnetically and releaseably attachable trigger for an instrument is provided. Additionally, the trigger provides for an increased sensitivity of sound by being in direct physical contact with the surface on which it is attached.

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.

An accessory for modifying sound output of a musical instrument. The body of the instrument has a soundboard. The accessory includes a sound sensor, an actuator, a fastener, and a controller. The sound sensor engages the body and senses vibration of the body representing the sound output of the musical instrument. The actuator engages the soundboard and deforms the soundboard of the musical instrument so as to modify the sound output of the musical instrument. The sound sensor is preferably arranged distally to the actuator. The fastener engages the accessory to the musical instrument, to locate the actuator against the soundboard of the musical instrument. The controller is connected to the actuator and the sound sensor for receiving and analysing the sound output sensed by the sound sensor, and controlling the actuator in dependence on the sound output sensed by the sound sensor.

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.

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.

A playable, removable cover for use while playing an electronic cymbal is disclosed. The cover comprises an opening configured to enable a connector to be coupled to the electronic cymbal, The opening is located on a top of the electronic cymbal when the cover is installed on the electronic cymbal. The cover also comprises a plurality of seams. The plurality of seams are located underneath the electronic cymbal when the cover is installed on the electronic cymbal. The cover is made of a material that comprises elastic characteristics, which minimizes the creation of air gaps formed under the cover and enables one or more elements of the electronic cymbal to be delineated.
