摘要： A vibration generator includes a housing, a first vibrator, and a second vibrator. The first vibrator includes a hollow yoke having a through hole, a magnet disposed within the through hole of the yoke, and a first elastic support member. The second vibrator includes a coil disposed above or below the magnet within the through hole of the yoke, and a second elastic support member to which the coil is fixed and that is disposed to extend from the inside to the outside of the through hole of the yoke and that is fixed to the housing. The first vibrator vibrates at a first natural frequency in a direction connecting both side portions of the yoke. The second vibrator vibrates at a second natural frequency that is different from the first natural frequency, in the direction connecting the both side portions of the yoke.

摘要： A vibration generator includes a housing; a vibrator; an elastic member that connects the housing and the vibrator; and a driver that causes the vibrator to vibrate. The elastic member includes a housing connection portion that is connected to the housing, a vibrator support portion that supports the vibrator, and a spring portion that connects the housing connection portion and the vibrator support portion. The housing connection portion and the vibrator support portion are in the same plane. The spring portion is formed so as to be approximately perpendicular to the housing connection portion and the vibrator support portion.
