ACTUATOR FOR VIBRATING A SOUND BOARD IN A MUSICAL INSTRUMENT AND METHOD FOR ATTACHING SAME

摘要

In an actuator (50), a bobbin (511) to which a voice coil (513) is attached is disposed within a magnetic path space formed by a magnetic path forming section (52). A connecting shaft (514) is coupled to the bobbin (511), and a connection end portion (516A) at a distal end of the connecting shaft is connected to a sound board of a musical instrument. The length of the shaft (514) can be adjusted. When the actuator (50) is attached to the sound board, the length of the shaft (514) is adjusted and the connection end portion (516A) is connected to the sound board while a position of the voice coil (513) within the magnetic path space is maintained in a predetermined reference mounting position, in a state in which the magnetic path forming unit (52) is supported in a predetermined position by a support unit (55).
