Abstract: A solenoid stack for a piano incorporating an array of striker solenoids, each of which includes an outer shell, a coil disposed within the outer shell and having an axial passage extending through its entire length, an inner shell within the coil and a slug moving axially within the inner shell in response to selective energization of the coil. The slug is provided with a passage through its length, and the passage includes an internally threaded section which a threaded push rod engages such that an upper end extends above the slug and carries a pusher tip. An adjustable stop member is provided at the bottom of the slug to limit the stroke of each individual solenoid assembly. A mounting plate includes an array of apertures for receiving the striker solenoid assemblies (in threaded, press-fit or the equivalent engagement) within the keybed such that each solenoid assembly is juxtaposed with respect to an individual keytail. In one variation, the mounting plate is made up of a series of modules (each with two or more solenoid-receiving apertures) having offset fore and aft sections. A "top hat" mounting assembly is also disclosed by the use of which a unitary player assembly may be obtained.

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.

Abstract: A solenoid driving circuit contains solenoids, each of which is driven to produce a magnetic field for driving each of keys of a player piano. A NPN transistor is provided to allow or block a flow of current across each solenoid. The solenoid is connected between a DC power source for providing a source voltage and a collector of the NPN transistor whose emitter is grounded. A drive signal, which is subjected to pulse-width modulation, is supplied to a base of the NPN transistor, so that the NPN transistor is switched over between ON and OFF. A diode is introduced to provide prescribed forward voltage for attenuation of the current across the solenoid when the NPN transistor is turned OFF. Herein, an anode of the diode is connected to a connection between the solenoid and NPN transistor, while a cathode of the diode is connected to a cathode of a zener diode having prescribed reverse voltage. An anode of the zener diode is connected to the DC power source. An effective time constant of the solenoid is represented in a mathematical form using the forward voltage, reverse voltage and source voltage as well as a real time constant of the solenoid. So, the solenoid driving circuit designed in such a way that the effective time constant of the solenoid is sufficiently small as compared to a maximum value of an operating frequency of the key of the player piano (i.e., action cutoff frequency of the player piano).

Abstract: In an electronic musical instrument capable of producing a key touch feeling resembling one in playing the piano by the provision of a hammer which is interlocked with a key, key-on data and touch data are generated in response to downward displacement of the key. In this type of electronic musical instrument, key-on data and touch data are also generated when the hammer is displaced upwardly and downwardly due to bounding of the hammer independently of the movement of the key. A touch control characteristic is established usually by using touch data generated in response to key-on data. When, however, second key-on data has been generated within a predetermined length of time after generation of preceding first key-on data, a touch control characteristic for the second on data is established by using first touch data generated in response to the first key-on data. By this arrangement, a touch response control of a tone signal corresponding to the second key-on data generated due to the hammer bound is made in accordance with the first touch data corresponding to real key touch during depression of the key.
