  • Publication number: 20100220405
    Abstract: (Problem) To suppress vibration generated while rising of a reciprocating lens actuator using a piezoelectric element or the like as a driving source and to shorten a rising speed. (Solving Means) By setting a time of a rising portion to a period corresponding to a natural frequency of a driving source, it is possible to prevent resonance of the driving source while rising so as to suppress vibration after rising and to increase a rising speed. In addition, by returning to an original point before driving, it is possible to improve reproducibility of movement displacement of the input signal.

  • Publication number: 20100189304
    Abstract: [Problems] To provide a multifunction vibration actuator which has flat rising and falling frequency characteristic at the time of generation of bodily sensation vibration and which is stable for an input signal. [Means for Solving Problems] Flat frequency characteristics can be obtained by using a two-fold rotational symmetry frame type suspension, and miniaturization of the whole multifunction vibration actuator can be made by the user of the frame type suspension. With regard to the frame type suspension, use of protruded configuration of corner parts ensures the effect of absorption of deflection of the suspension.

  • Patent number: 7723873
    Abstract: A vibration actuator having a simple small-sized structure capable of obtaining vibration enough to sense without use of suspension or the like is provided. Amplitude of a moving part is restrained by a magnetic gap formed by cup-shaped yokes which are formed to interpose a magnet, and the moving part is vibrated without collision of the moving part with an inner wall of a fixed part. Therefore, magnetic force exerted between the moving part and the fixed part is allowed to function as a suspension. Therefore, it is possible to solve a problem, that is, reduction in the amplitude caused from the suspension. In addition, an air damper structure that air in upper and lower space of the moving part is used as a damper is provided, so that it is possible to obtain a wide frequency band.

  • Publication number: 20100093220
    Abstract: A contact terminal which prevents a load from being concentrated on the contact terminal portion thereof when a part is disposed on a substrate, to prevent contact terminals from being short-circuited even if stacked, thereby reducing the overall space requirement. A projection is formed on a terminal base and the movable range of a contact is limited by the projection, whereby the load that is conventionally concentrated on a terminal support part can be distributed by a support part and the projection. Consequently, the durability of the terminal portion can be enhanced, the space for the contact terminal portion is saved, and a short circuit is prevented from occurring due to the contacting between the contact terminals.
