    • It is disclosed a device which includes an elongated member, and an energy convertor. The elongated member has a base side and a free end. A certain direction is defined by a line connecting centers of the base side and the free end. The free end oscillates relative to the base side, in a response to a mechanical excitation, in a direction substantially perpendicular to the certain direction. The energy convertor converts mechanical energy of the oscillations of the free end to electrical energy. The energy convertor includes a coil attached to the free end, and a permanent magnet tightly fixed to the base side. Mechanical oscillation of the coil relative to the permanent magnet induces a flow of alternate current from the energy convertor. The energy convertor is electrically connected to a current rectifier for rectifying the alternate current, whereas the rectified direct current feeds a battery. The device is installed within a host mobile device, and the base side is fixed to the host mobile device. The device is enclosed within a vacuum chamber such as to prevent dissipation of energy of the mechanical oscillation by air friction.
    • 公开了一种包括细长构件和能量转换器的装置。 细长构件具有基部侧和自由端。 一定方向由连接中心的基座侧和自由端的线限定。 自由端在大致垂直于该特定方向的方向上相对于机械激励而相对于基座侧振荡。 能量转换器将自由端的振荡的机械能转换为电能。 能量转换器包括附接到自由端的线圈和紧固在基座侧的永磁体。 线圈相对于永磁体的机械振荡引起来自能量转换器的交流电流。 能量转换器电连接到电流整流器以整流交流电流,而整流的直流馈电电池。 该设备安装在主机移动设备内,并且基座侧固定到主机移动设备。 该装置封闭在真空室内,以防止机械振荡的能量通过空气摩擦而耗散。
