摘要： An elongated lifting rail is displaceable to collectively pivot a plurality of damper levers. An actuator is provided beside or underneath the lifting rail for automatically displacing the lifting rail. The lifting rail is displaced, in response to driving of the actuator, to displace the damper levers so that the dampers are moved away from contact with sounding members. Further, a position sensor is provided for detecting a displaced position of the lifting rail, so that position data detected by the position sensor is used for operating position control and/or operating position recording of the dampers.

摘要： An actuator includes a movable member that, when moving, abuts against a key (performance operator) to move the key. A first sensor detects motion of the key. A second sensor detects motion of the movable member. A processor determines, based on outputs of the sensors, whether or not the key and the movable member are currently in a mutually separated state. When the key and the movable member are in the mutually separated state, the processor controls the actuator in such a manner that the key and the movable member are in contact with each other. When the key and the movable member are not in the mutually separated state, the processor controls the actuator by use of feedback information based on the output of the first sensor, whereas, in the mutually separated state, the actuator is controlled by feedback information based on at least the second sensor output.

摘要： A musical instrument 1 according to an embodiment includes a sound board 7 configured to transmit a vibration of a sound source, and an exciter device 50 configured to vibrate the sound board 7 based on an input signal. The exciter device 50 includes a vibration exciter 51 disposed in contact with the sound board 7 and configured to vibrate the sound board 7, and a support part 52 attached to the sound board 7 and supporting the vibration exciter 51. The support part 52 includes an elastic displacement part 521 configured to be elastically displaced with respect to the sound board 7. The elastic displacement part 521's natural frequency is equal to or lower than a frequency corresponding to a highest peak among a plurality of peaks in a frequency characteristic of the vibration exciter 51.

摘要： In a player piano, a position sensor is provided cm an end portion of a lifting rail for detecting a vertical position of the lifting rail. In storing performance data of dampers, a signal output from the position sensor and indicative of a vertical position of the lifting rail is converted into a digital signal, and a position value indicative of the position of the lifting rail is generated on the basis of the digital signal and stored into a buffer. A conversion section converts the position value into a vertical position of a pedal rod connected to a damper pedal, and the thus-converted vertical position is converted, into a control value which a control change message of the damper pedal in MIDI-format data can take. The control value obtained in the aforementioned manner can be recorded into a recording medium as performance information.
