Vibration generator and electronic apparatus
摘要：
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).
摘要（中）：

提供了一种振动发生器（40），其中具有不平衡器的转子旋转。 所述振动发生器包括具有安装在其上的扁平线圈基板（120）的底板（47），垂直于所述底板设置的固定轴（91），具有自由地安装在所述固定轴（91）上的磁体（85） 可旋转轴承设置在它们之间并且在它们之间具有微小间隙并且安装到磁体（85）上的重物（87）布置在平面线圈基板（120）的表面上。 为了产生振动，向扁平线圈基板（120）上的线圈提供电流以使磁体（85）和重物（87）旋转。 底板（47）由非磁性材料形成。 薄磁板（48）安装在与磁体（85）相对的一侧，底板（47）位于薄磁板（48）和磁体（85）之间。
