    • An installation structure for an acoustic transducer for vibrating a vibrated body in a first direction includes a magnetic-path forming portion; a movable unit having an electromagnetic coupling portion and configured to vibrate in the first direction; an attachment portion which attaches the magnetic-path forming portion to a fixed portion; a connector connected to the vibrated body and connecting the movable unit to the vibrated body; and a displacement permitting mechanism configured to permit electromagnetic coupling between the magnetic-path forming portion and the electromagnetic coupling portion to be maintained and to permit the vibration of the movable unit to be transmitted to the vibrated body when the connector is displaced with respect to the fixed portion within a predetermined range in an intersecting direction that intersects the first direction. The displacement permitting mechanism is provided at at least one of the attachment portion, the movable unit, and the connector.
    • 用于在第一方向上振动振动体的声换能器的安装结构包括磁路形成部分; 具有电磁耦合部分并被构造成在第一方向上振动的可移动单元; 附接部,其将所述磁路形成部附接到固定部; 连接到所述振动体并将所述可动单元连接到所述振动体的连接器; 以及位移允许机构,其构造成允许在所述磁路形成部分和所述电磁耦合部分之间保持电磁耦合,并且当所述连接器相对于所述电磁耦合部分移动时允许所述可移动单元的振动传递到所述振动体 固定部分在与第一方向相交的交叉方向上的预定范围内。 位移允许机构设置在附接部分,可移动单元和连接器中的至少一个上。
