An installation structure for an acoustic transducer that operates in accordance with an audio signal to thereby vibrating a vibrated body in a first direction for permitting the vibrated body to generate sounds, including: a magnetic-path forming portion fixedly disposed relative to a fixedly supporting portion; a movable unit having an electromagnetic coupling portion electromagnetically coupled to the magnetic-path forming portion and configured to vibrate in the first direction when the electromagnetic coupling portion is driven by the magnetic-path forming portion in response to a drive signal based on the audio signal; a connector fixed to the vibrated body and connecting the movable unit to the vibrated body for transmitting vibration of the movable unit to the vibrated body; and at least two restricting mechanisms fixedly disposed relative to the fixedly supporting portion for restricting a movement of the movable unit in a second direction intersecting the first direction.
