The present disclosure proposes a keybed device, including: a keybed support; a keybed arranged on the keybed support; a key height limiting column arranged in one-to-one correspondence with each key in the keybed, and an end of the key height limiting column is fixed on a bottom surface of the corresponding key; a pressure detecting device arranged in one-to-one correspondence under each key height limiting column to detect a pressing strength of each key height limiting column; and a flexible support structure arranged below each key height limiting column and located on at least one side of each pressure detection device. The keybed device includes a flexible support structure, which can avoid false triggering of the Aftertouch effect. A same depth is pressed down from the flexible support structure to obtain a consistent Aftertouch effect, and the performance effect is controllable.

A highly configurable controller is described that includes a number of different types of control mechanisms that emulate a wide variety of conventional control mechanisms using pressure and location sensitive sensors that generate high-density control information which may be mapped to the controls of a wide variety of devices and software.

A playground structure may include a body, a piezoelectric sensor carried by the body and configured to detect a touch input on adjacent portions of the body, and an output device configured to generate audio indicators. The playground structure may include a controller coupled to the output device and the piezoelectric sensor and configured to selectively change the audio indicators based upon the touch input.

A device is provided for capturing vibrations produced by an object such as a musical instrument such as a cymbal 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.

A signal supply device according to an embodiment of the present invention includes a generator configured to generate a first sound signal and a second sound signal in accordance with an instruction signal including operation body information corresponding to an operation input to an operation body and linked member information corresponding to a movement of a linked member linked with the operation body and an adjuster configured to adjust a relationship between the first sound signal and the second sound signal on the basis of the operation body information and the linked member information.

Described herein is a flexible piezoresistive switch sensor responding only to a minimum threshold compression deformation force. The switch sensor comprises a non-porous housing that separates an external environment from an internal environment; one or more decoupled electrodes comprising or formed of a flexible conductor; a non conductive insulating spacer layer enforcing the one or more decoupled electrodes in bending or twisting forces, while allowing electrode coupling due to compression; a piezoresistive layer decoupled from the electrodes via the insulating spacer layer; and an elastomeric polymer layer comprising one or more buckling or spring elements configured to separate a minimum required compression force on the piezoresistive layer and the non-conductive insulating layer.

A controller for musical instrument models is presented, comprising acoustic elements with embedded vibration sensors that the user actuates for example by plucking, strumming, or striking the elements. A vibration sensor attached to each acoustic element is used to generate an excitation signal for musical instrument models. A note input interface can be included so that note input such as MIDI can be used to control the musical pitch of the musical instrument models.

This disclosure relates generally to electronic methods. More musical instruments, systems, and particularly, this disclosure relates to electronic percussion instruments such as tom toms, snare drums, bass drums, cymbals, and hi-hats, and assemblies of instruments (e.g., percussion instruments), such as drum sets. Even more particularly, this disclosure relates to wireless electronic percussion instruments, and percussion instruments with interchangeable and/or removable components to change the instrument between a traditional percussion instrument (that relies on resonance and/or vibration to produce sound) and an electronic percussion instrument. The present disclosure also relates to electronic cymbal instruments, such as cymbal assemblies and hi-hat assemblies, that can be used in conjunction with a traditional acoustic metal cymbal.
