タ。−A solenoid coil wound around a bobbin is placed between an upper differential yoke and a lower common yoke, and a plunger yoke is placed inside the bobbin so as to be movable in the axial direction, and an actuator head is attached to the tip of the plunger yoke. When installed, the solenoid coil is energized based on information about the movement of the keys on the piano keyboard, etc., to generate a thrust force that moves the plunger yoke upward, and this thrust pushes the key upward, similar to pressing the key with a finger. Perform the operation automatically
In the actuator of the automatic piano performance device, a pair of cylindrical plate yokes with a gap in the middle are arranged coaxially with the bobbin, and insert molding is performed so that the contact surface with the plunger yoke is made of bobbin material. An actuator for an automatic piano performance device featuring: −
