Windows.

  A vibration element called an actuator exciter can be used for the vibration generator. As the former actuator, there is an actuator using a giant magnetostrictive element or a piezoelectric element. An example of the giant magnetostrictive actuator is a structure in which a giant magnetostrictive rod is expanded and contracted by a magnetic field change generated by an electromagnetic coil. In the casing, an electromagnetic coil, a rod made of a giant magnetostrictive element, a spring for applying a biasing force in the compression direction to the giant magnetostrictive rod, and a magnet for applying a bias magnetic field to the giant magnetostrictive rod are housed. The giant magnetostrictive rod is expanded and contracted by a magnetic field change based on an audio signal input to the electromagnetic coil, and the plate member is vibrated by the displacement to generate a sound wave.

  On the other hand, the vibration element called the exciter uses a voice coil, and includes a voice coil wound around a bobbin portion and a magnetic circuit that forms a magnetic gap between the voice coil. The voice coil is vibrated on the basis of the voice signal input to the bobbin, and the bobbin is caused to move in a piston motion. As a result, the plate member abutted on the bobbin is vibrated to reproduce the sound. . Magnetic circuits include an outer magnet type and an inner magnetic type.
