Patent number: 7161269Abstract: There is provided a vibration generator (40) in which a rotor with an unbalancer is rotated. The vibration generator includes a bottom plate (47) having a flat coil substrate (120) installed thereto, a stationary shaft (91) provided perpendicularly to the bottom plate, a magnet (85) installed on the stationary shaft (91) with a freely rotatable bearing being disposed between them and opposite to the surface of the flat coil substrate (120) with a slight clearance defined between them, and a weight (87) installed to the magnet (85). For generating a vibration, a current is supplied to the coil on the flat coil substrate (120) to rotate the magnet (85) and weight (87). The bottom plate (47) is formed from a nonmagnetic material. A thin magnetic plate (48) is installed at the side opposite to the magnet (85) with the bottom plate (47) being placed between the thin magnetic plate (48) and magnet (85).Type: GrantFiled: June 3, 2004Date of Patent: January 9, 2007Assignees: Sony Corporation, Omron CorporationInventors: Shun Kayama, Yukiko Shimizu, Masahiro Suzuki, Toshinori Yamasue, Hiroshi Azuma, Hirokazu Kitamura

Patent number: 7157822Abstract: A driver IC and passive parts, which convert a direct current voltage into a three-phase voltage, and an FP coil for cyclically generating a magnetic field through the driver IC are mounted on a flexible substrate, which constitutes a small vibration motor. The driver IC is a so-called bare chip in which a circuit section is exposed and is not molded with resin and the like. Magnets and an unbalance weight are installed on a yoke having a shaft. The FP coil and the magnet are placed so as to face each other. A cover is caulked to fixed to a bottom plate. Thus, the vibration motor can be miniaturized and thinned. Moreover, the vibration motor can be automatically manufactured, and installing them to an electronic apparatus can be automatically performed.Type: GrantFiled: July 23, 2003Date of Patent: January 2, 2007Assignee: Sony CorporationInventors: Koji Yoshida, Shun Kayama, Katsuhiro Yoneyama, Yukiko Shimizu

Patent number: 7042653Abstract: A first arm rotating within a predetermined angle about its rotational center is linked to a second arm rotating in a direction opposite to a rotation direction of said first arm. Two shrinking members are mounted on one end of the first arm. Two shrinking members shrink in opposite directions for each other each time when any one of them is energized. According to a switch of electricity to the two shrinking members, the first arm rotates to switch a rotational position thereof, with the second arm rotating to switch a rotational position of the second arm.Type: GrantFiled: August 30, 2004Date of Patent: May 9, 2006Assignee: Sony CorporationInventors: Yukiko Shimizu, Shun Kayama
