    摘要： A resin film is disposed facing an upper surface of a diaphragm with a gap interposed therebetween. The gap is provided between a lower surface of the resin film and the upper surface of the diaphragm in a tactile feedback keyboard. Consequently, it is possible to secure a key stroke from the resin film to the upper surface of the diaphragm, and make a user feel a sense of an operation that the user has pushed a key. Further, the gap and the resin film reduces the vibrations from the diaphragm reaching an operation surface. Thus, the user feels the vibrations of the diaphragm via only a finger which has pushed the resin film until the resin film contacts the upper surface of the diaphragm, and the other fingers hardly feel the vibrations.

    摘要： A vibration structure that includes a film constructed to deform in a plane direction as voltage is applied thereto, a frame-shaped member, a vibration portion surrounded by the frame-shaped member in a plan view of the vibration structure, a support portion connecting the vibration portion and the frame-shaped member and supporting the vibration portion within the frame-shaped member, a first connection member that connects the film and the frame-shaped member, and a second connection member that connects the film to the vibration portion such that the vibration portion vibrates in the plane direction when the film is deformed in the plane direction. The support portion is disposed at a position closer to a center of gravity of the vibration portion than an end portion of the vibration portion when viewed in the plan view.

    摘要： A tactile feedback device includes a vibrating device and a touch sensor. The vibrating device comprises a flexible diaphragm and a film which deforms in response to the application of electrical energy thereto, the film being attached to the flexible diaphragm at two spaced locations with a major surface of the film facing a major surface of the flexible diaphragm. The vibrating device further includes a spacer located between the two spaced locations and ensuring that the major surface of the flexible diaphragm is spaced from the major surface of the film. The touch sensor is coupled to the diaphragm and generates an output signal in response to a touch operation. Means are provided to apply electrical energy to the film in response to the output signal.

    摘要： A vibration structure that includes a film having a first electrode on a first main surface thereof, the first electrode defining a first connection region on the first main surface where the first electrode is not present, and the film is constructed to be deformed in a plane direction when a voltage is applied thereto; a frame-shaped member; a vibration portion surrounded by the frame-shaped member; a first connection member that connects the first main surface of the film to the frame-shaped member at the first connection region; a second connection member that connects the film to the vibration portion; and an extended electrode that is connected to the first electrode.

    摘要： A vibration structure that includes a film constructed to deform in a plane direction as voltage is applied thereto, a frame-shaped member, a vibration portion surrounded by the frame-shaped member in a plan view of the vibration structure, a support portion connecting the vibration portion and the frame-shaped member and supporting the vibration portion within the frame-shaped member, a first connection member that connects the film and the frame-shaped member, and a second connection member that connects the film to the vibration portion such that the vibration portion vibrates in the plane direction when the film is deformed in the plane direction. The support portion is disposed at a position closer to a center of gravity of the vibration portion than an end portion of the vibration portion when viewed in the plan view.
