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).
摘要（中）：

在致动器（50）中，安装有音圈（513）的线轴（511）设置在由磁路形成部（52）形成的磁路空间内。 连接轴（514）联接到线轴（511），并且连接轴的远端处的连接端部（516A）连接到乐器的声板。 可以调节轴（514）的长度。 当致动器（50）附接到声板时，轴（514）的长度被调节，并且连接端部（516A）连接到声板，而音圈（513）在磁性 在通过支撑单元（55）将磁路形成单元（52）支撑在预定位置的状态下，将路径空间保持在预定的基准安装位置。
