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).

摘要： An audio signal that is output from a sound source circuit (14) is caused to flow through a coil (16) in a transducer for vibrating a soundboard, and the vibration of the soundboard generates an acoustic signal. A microcomputer (30) calculates a temperature of the coil (16) with high accuracy by inputting an ambient temperature (Ta) detected by an ambient temperature sensor (21) and a voltage (V) applied to the coil (16) and executing computation based on a thermal equivalent circuit of an acoustic signal converter using the ambient temperature and the voltage that are input thereto, the computation including calculation of an amount of electric power consumed in the coil (16) using the input voltage.
