摘要： A speed detecting apparatus for a keyboard musical instrument is provided for accurately detecting the speed of bivotal movements of a hammer and a key even if a shutter implies errors in its attachment, without affected by such errors. The speed detecting apparatus for a keyboard musical instrument comprises a pivotable key, a hammer pivotably supported by a fulcrum and configured to pivotally move in association with a pivotal movement of the key, a shutter integrally attached to the hammer, a plurality of detectors, each having a light emitter and a light receiver for receiving light emitted from the light emitter, arranged on one and the other sides of the pivotal movement path of the shutter, and a CPU for detecting a pivot speed of the hammer in response to timings at which the shutter opens and closes the light paths of the light of the plurality of detectors when the hammer pivotally moves. The plurality of detectors have detection points on respective light paths of the light from the light emitters, and are arranged such that the detection points are positioned on an arc centered at the fulcrum of the hammer.

摘要： In an automatic player piano, hammer sensors monitor associated hammers so as to report current positions on the hammer trajectories, and a data processor analyzes the hammer motion for producing pieces of music data representative of the performance on the acoustic piano; the aged deterioration is influential in the relative position between the hammers and the hammer sensors so that the data processor rectifies the relative position, the data processor determines the turning point at which the hammer changes the direction of motion, and compares the current value indicating the turning point with the previous value; if the difference is found, the data processor adds a value of deflection of strings to the current value so as to determine and memorizes the true value of the turning point; the data processor analyzes the hammer motion on the basis of the true value so that the music data are reliable.

摘要： 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.

摘要： Provided is a musical instrument including a vibratable body; and a vibrator. The vibrator includes a vibrating body that vibrates in a predetermined direction; and a coupling member coupling the vibrating body and the vibratable body and that transmits vibration of the vibrating body to the vibratable body. The coupling member includes a shaft extending between the vibrating body and the vibratable body; a first wire rod coupling one end portion of the shaft and the vibrating body; and a second wire rod coupling another end portion of the shaft and the vibratable body. A resonance frequency of each of the shaft, the first wire rod, and the second wire rod is at least 10 kHz.

摘要： A modulated electromagnetic musical instrument and sound reproduction system includes an acoustic carrier signal source, a modulation signal source, a linkage element, and an acoustic output. The acoustic carrier signal source is produced electromagnetically or mechanically via human instrument playing. An electromagnetic modulation source mixes with the acoustic carrier signal within a linkage element to produce a nonlinear behavior. This nonlinear behavior's coupled interaction with a physical medium or acoustic body produces sideband frequency components to form unique musical sound outputs and audio effects.
