Abstract
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.
Claims15
A damper drive device for a musical instrument, comprising:
- a plurality of dampers each configured to be displaceable to damp vibration of a corresponding sounding member of the musical instrument;
- a plurality of damper levers each configured to be pivotable to displace a corresponding one of said dampers;
- an elongated member configured to be displaceable to collectively pivot said plurality of damper levers;
- and
- an actuator disposed beside or underneath said elongated member for displacing said elongated member,
- wherein said elongated member is displaced in response to driving of said actuator so that said dampers are displaced away from contact with the sounding members.
A musical instrument comprising:
- a plurality of sounding members;
- a plurality of dampers each configured to be displaceable to damp vibration of any one of said sounding members;
- a plurality of damper levers each configured to be pivotable to displace a corresponding one of said dampers;
- an elongated member configured to be displaceable to collectively pivot said plurality of damper levers;
- a damper pedal operable by a user;
- a pedal mechanism configured to displace said elongated member in response to depressing operation of said damper pedal so that said dampers are displaced away from contact with said sounding members;
- and
- a sensor configured to detect a displaced position of said elongated member.
