A sound source for an electronic percussion instrument and sound production control method thereof are provided. An electronic drum sound source device performs a weighting operation on four pieces of waveform information (pitch envelope, amplitude envelope, start phase) stored in a waveform table according to the beating conditions (hitting point position, velocity) based on the output from a struck sensor of an electronic drum pad. The electronic drum sound source device creates a sine wave on the basis of the waveform information whereon the weighting operation was performed, and generates musical sounds (sounds of percussion instrument) by synthesizing the sine wave with the waveforms of residual waveform data whereon the weighting operation was performed. The sine wave is not synthesized with waveform data other than the residual waveform data, and thus consistent musical sounds with no phase interference can be reproduced.

A sensing system for a computer input device. The sensing system comprises an actuator to attach to a key top or button. The actuator is moveable along an axis or hinged. The sensing system further comprises a biasing element to exert a biasing force on the actuator directed along the axis. The sensing system further comprises an actuator motion sensor associated with the actuator. The actuator motion sensor comprises a passive resonant circuit configured to be moved by the actuator and having a resonant frequency, an active resonant circuit configured to excite the passive resonant circuit at the resonant frequency, a sensor driver to drive the active resonant circuit with an RF drive signal at the resonant frequency, and a detector to detect a level of RF signal from a driven actuator motion sensor for sensing a position and/or velocity of the actuator.

A stick device that includes a base and a tip end, and a tip secured to the tip end of the stick, the stick tip including a sensor. The stick including the base thereof, and includes at least one control button, a communication element, and a processor in communication with the at least one control button, the stick tip and the communication element. The processor is configured to receive a signal from the stick tip and to generate output to the communication element. The output so generated includes a signal that specifies a sound file selected by operation of the at least one control button.

A vibraphone pickup has a bobbin having two coils, one for outputting an analog signal and one for outputting a digital signal. A plurality of filters and buffers are used to isolate the signals. A rare earth (or neodymium) magnet is used in the center of the bobbin. In one method of use, a vibraphone pickup is used to pick up each note of the vibraphone. The output of each vibraphone pickup is combined and fed into an amplifier.

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 invention eliminates most mechanical switching in vibrational pickup circuits by using variable gains to combine signals of sensors in differential amplifiers as J−1 humbucking pairs for J>1 number of sensors, with the sensors matched to produce the same level and phase of unwanted hum from external sources. It can also combine J>1 number of matched sensors with K>1 number of dissimilar sensors which are matched only to each other in the same manner. This produces not only all the possible mechanically switched humbucking signals, but all the continuously-varying combinations of humbucking signals in between.

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 supporter (10) attaches a kick pad to be beaten with a beater to a stand installed on a floor surface. The supporter (10) includes an elastic member (1) that fixes the kick pad to one end as viewed in a direction intersecting with a direction in which the kick pad is beaten with the beater, and that fixes the other end as viewed in the intersecting direction to the stand.
