  • Patent number: 8962966
    Abstract: In response to an operation of a key, a drive signal indicating a sound waveform corresponding to the key is supplied to an excitation unit provided on a soundboard. The soundboard is vibrated in response to a mechanical vibration generated by the excitation unit and generates an actively-vibrated-soundboard sound as well as an acoustic effect generated by propagation of the vibration of the soundboard to a string. The excitation unit has a voice coil excited by the drive signal. The length of the voice coil is equal to or smaller than a sum of a magnetic path width (mw) of a magnetic path space and a double of a maximum deflection amount (sw) of the vibration member connected to the soundboard. In this way, an effective drive force for exciting the soundboard can be obtained and an enhanced responsiveness in a high frequency band can be obtained.

  • Patent number: 8927847
    Abstract: A time-varying formant is generated at a formant frequency by generating first and second harmonic phase signals having first and second harmonic numbers, respectively, in relation to a modulation frequency. The first and second harmonic phase signals are generated in proportion to a master phase signal, which varies at the modulation frequency, modulo a factor corresponding to their harmonic numbers. First and second sound signals, based on the first and second harmonic phase signals, are frequency modulated to create an arbitrarily rich harmonic spectrum, depending on an FM index. The time-varying formant is generated by generating a time-varying combination of the first and second harmonic sound signals, weighting the first and second harmonic sound signals in accordance with their spectral proximities to the formant frequency. One or more of the harmonic numbers are updated when the time-varying formant frequency passes the frequency of either sound signal.

  • Patent number: 8217254
    Abstract: In an implementation of this invention, a stringed musical instrument has a resonator comprised of a bridge and a soundboard. Vibrations from the strings are transmitted through the bridge to the soundboard. A plurality of sensors are attached to or embedded in the soundboard. The sensors measure primarily the vibrations of the soundboard, rather than primarily the vibrations of the strings. Preferably, three or more sensors are used. Piezoelectric sensors sample vibrations in the soundboard. The resonator includes a printed circuit board that amplifies the signal from each sensor separately. Also, a signal processing device that is “onboard” the musical instrument processes the separate input signals to create one output signal. The resonator may be easily removed, enabling resonators to be interchanged. Also, the physical characteristics of a particular resonator, such as its mass or its boundary condition, may be adjusted, thereby changing the acoustic qualities of the soundboard.

  • Patent number: 7345235
    Abstract: Keys of an acoustic piano require balancers for cancellation of a part of self weight of the action units/hammers; however, the balancers are liable to be dropped off due to the aged deterioration of the wooden bars; in order to keep the balancers stable in the keys against the aged deterioration, the balancer is plastically deformed so as to bite into the wooden bar, the balancer, which is formed with thorns, is rotated so as to make the thorns bite into the wooden bar, the balancer is shaped into a configuration different from the holes so as to exert resilient force on the inner surface in a direction in parallel to the grain of wood, or the balancer is inserted into a constricted hole so as to strongly exert the resilient force on the inner surface, thereby being prevented from the dropping off from the keys.

  • Patent number: 7268289
    Abstract: A set of formation data codes, which includes action event codes and duration codes, is loaded in an automatic player piano, and a controller interprets the action event codes for driving the solenoid-operated key actuators; since the solenoid-operated key actuators slowly push the associated keys, the hammers do not reach the strings, and any piano tone is not produced; the plungers make the keys sunk to different depth so that the keys are laid on a artistic pattern; the controller sequentially changes the artistic pattern, and offers an artistic visual expression to the audience.

  • Patent number: 7253349
    Abstract: A 2 manual musical keyboard with the pitch progression on one of the manuals reversed. The keys on these manuals are segregated into 2 groups of 2 different heights in the same way as a standard musical keyboard. The key configurations on these manuals have 12 semi-tones linearly distributed across 12 keys of alternating heights. Instead of the traditional 7 lower keys (white) and 5 upper keys (black), this arrangement has 6 lower keys and 6 upper keys. The notation system for this unique keyboard is a dual character set. Six unique characters for the upper keys and six unique characters for the lower keys. The musical staff for this unique keyboard will have six lines assigned to one character set and the six spaces assigned to the other character set.

  • Patent number: 7202409
    Abstract: An automatic player piano includes keys driven for the angular motion through a hybrid feedback control loop; a controller, a key position sensor, a plunger velocity sensor and a solenoid-operated key actuator form parts of the hybrid feedback control loop for each key, and a current key position and a plunger velocity are reported to the controller; the controller determines a series of target position or a reference trajectory and a target velocity, and periodically compares a composite current position and a composite current velocity, which are determined on the basis of the current key position and current plunger velocity, with the target position and target velocity to see whether or not the key travels on the reference trajectory; if the answer is negative, the controller adjusts the driving signal to a proper duty ratio so as to force the key to travel on the reference trajectory.

  • Patent number: 7002070
    Abstract: An electronic piano is provided in which activation of a keyboard (7) and foot pedals (8) causes sound to be generated and output via a pair of conventional cone loudspeakers (210–212) each comprising a tweeter (214), a woofer (216) and a base (218). Simultaneously with the activation of the conventional cone loudspeakers (210, 212), sound corresponding to the notes played by using the keyboard (7) is also generated and output via two distributed mode loudspeakers (220, 222) which are arranged to output sound through the inducement of resonant vibrations. The conventional cone loudspeakers (210–212) act as a series of discrete point sound sources. The distributed mode loudspeakers (220, 222) act as diffuse point sources generating sound across the entire surface area of the panels (220, 222). The air disturbance patterns propagated by the two different types of sound source result in sound more closely emulating the sound generated by a conventional high quality acoustic grand piano.

  • Patent number: 6867359
    Abstract: A silent piano is available for a performance through electronic tones, and a player can give a timbre different from that of an acoustic piano to the electronic tones; when the player specifies a timbre of another acoustic musical instrument having a compass narrower than the compass of the acoustic piano, the key levers outside of the compass are never depressed in the performance, and several musical performance styles such as mute, glissando, tremolo and so fourth are assigned to the idle key levers; while the player is fingering on the keyboard, the player depresses one of the idle key levers and, thereafter, the black and white key levers in the compass, then, the electronic tones are produced in the selected musical performance style; the idle key levers are not mixed in the compass so that the player is less liable to be mistakenly depress the idle key levers.

  • Patent number: 6703552
    Abstract: An apparatus and method for continuous keyboard system. The Continuous Music Keyboard resembles a traditional keyboard in that it is approximately the same size and is played with ten fingers. It also resembles a fretless string instrument in that it has no discrete pitches; any pitch and any tuning may be played, and finger movements produce smooth glissandi and vibrato. The Continuous Music Keyboard comprises a plurality of rods, each of which has a magnet on each end. The displacement of each rod is measured through mounted Hall-Effect sensors. The sensor values are then analyzed to identify the three-dimensional location of the fingers depressing upon a control surface. Additionally, predictive analysis is conducted on values collected to identify whether a new depression on the control surface has occurred, or rather if a previously placed finger is simply moving alone the Continuous Music Keyboard.

  • Publication number: 20030196541
    Abstract: An acoustic control system for an electronic musical instrument, which can obtain optimal acoustic characteristics irrespective of whether or not a low range speaker is attached to a body thereof. A piano body has high range and mid range speakers. A low range speaker is removable from the body. A stand-excluding switch designates a first speaker-use mode for using the high range and mid range speakers alone, and a stand-including switch designates a both speaker-use mode for using both the high range and mid range speakers and the low range speaker. A ROM stores stand-excluding and stand-including factors for setting acoustic characteristics in the two modes, respectively. A CPU reads one of the factors, which corresponds to the mode designated by the stand-excluding or stand-including switch. A tone generator circuit generates a musical tone signal to be reproduced in one of the modes, based on the read factor.
