    摘要： A method and apparatus for self-tuning a piano that optically senses the vibration of all the piano's strings independently and simultaneously. Interference caused by alternating-current ambient lighting is removed by modulating the string's signal onto a high-frequency carrier wave, filtering out the low-frequency ambient light interference wave, then demodulating and removing the carrier to render the original signal. Digital pitch, diagnostic, and control parameter information is interchanged between a supervisory master microcontroller and the autonomous string sustainer circuits via a master-slave serial bus connected through a single, common cable. PWM duty cycles for the string tuning coils are handled autonomously by an FPGA or a decoder network, which also communicates with the master control circuit. Pulse-width modulated control signals are filtered to a DC control voltage and combined with a drive oscillator signal using a summing amplifier to eliminate audible noise due to magnetostriction in the tuning coils.

    摘要： An adaptive equipment for playing chords on a musical instrument is provided. The apparatus can have a shell having an interior cavity. The adaptive equipment has a root pin partially installed within a root housing channel of a root housing, the root housing is fixedly installed within an interior cavity of the shell and is positioned toward the left side of the shell. The adaptive equipment has a fifth pin partially installed within a fifth housing channel of a fifth housing, the fifth housing is fixedly installed within the interior cavity of the shell and is positioned toward the right side of the shell. The adaptive equipment has a third pin partially installed within a third housing channel of a third housing, the third housing is movably installed within the interior cavity of the shell and is positioned between the root housing and the fifth housing. The root pin, the third pin and the fifth pin correspond to a major triad on a piano keyboard when the third housing is positioned closer to the fifth housing. The root pin, the third pin and the fifth pin correspond to a minor triad on the piano keyboard when the third housing is positioned closer to the root housing.

    摘要： An upright keyboard musical instrument has an open/close board attached to the top position of a case, wherein the lower surface of the open/close board is subjected to mirror surface finishing and is supported by a lid prop, which is rotatably arranged in proximity to the top board to rotate about a support axis and is formed in an L-shape to have a plurality of support surfaces, realizing different angles for the open/close board being opened. The mirror surface of the open/close board projects images representing internal members of the case, such as an emblem and actions. By appropriately rotating the lid prop, it is possible to realize a desired angle for the open/close board, thus realizing tone volume control and visually entertaining effects in musical performance.

    摘要： A safety device used on pianos to prevent the slamming of keyboard lid. Present invention uses a suction cup with a rod that can be folded down, so that it takes up very limited room, when it rod is down. When in use, if the piano keyboard lid is tilted towards the closing position, a rubber roller on top of the rod will contact the inner surface of the lid and stop the falling motion, preventing injuries to piano player's hand or fingers. The inner 90-degree angle of the lid will serve as a catch-well for the rubber roller to prop up the lid.
