    • An apparatus and method are provided for advantageously powering a headset without a power cable. In one example, a headset includes a processor, an acoustic transducer, and a kinetic energy converter operably coupled to a power cell for powering the headset, the kinetic energy converter capable of converting kinetic energy of the headset into an output charge for charging the power cell. Advantageously, the present disclosure provides for reliably and efficiently powering a headset without having to replace or dock a headset battery and without requiring power cables.
    • 提供了一种装置和方法,用于在没有电力电缆的情况下有利地为耳机供电。 在一个示例中,耳机包括处理器,声换能器和可操作地耦合到用于为耳机供电的功率单元的动能转换器,所述动能转换器能够将头戴耳机的动能转换成用于对功率进行充电的输出充电 细胞。 有利地,本公开提供可靠和有效地为耳机供电,而不必更换或对接耳机电池并且不需要电力电缆。

    • Mechanisms for providing electrical controls on a rotating assembly such as a cable winding device are disclosed. The cable winding device generally includes an electronic control actuator such as a keycap attached to a housing and providing an actuating pad actuatable via an opening provided in the housing, the housing containing a spool, a circuit component including an electronic control such as a switch actuatable via the actuating pad, and a rotational actuator interface such as a skid pad located over the electronic control to interface between the actuator pad and the electronic control at all rotational orientations of the switch relative to the actuating pad and/or even while the spool is rotating. The circuit component and the skid pad are configured to rotate with the spool relative to the housing. The switch is disposed off of an axis of rotation and may be, for example, an answer/end, on/off, mute, volume, play/stop, rewind/fast forward, and/or enter/accept control. The cable winding apparatus may be incorporated in a headset system.
    • 公开了一种用于在诸如电缆缠绕装置的旋转组件上提供电气控制的机构。 电缆缠绕装置通常包括电子控制致动器,例如附接到壳体的键帽,并且提供可通过设置在壳体中的开口致动的致动衬垫,壳体包含线轴,包括电子控制器的电路部件,例如可开关的开关 以及旋转致动器接口,例如位于电子控制器上方的滑动垫,以在开关的所有旋转取向相对于致动垫和/或甚至当阀芯为止时在致动器垫和电子控制器之间接合 旋转。 电路部件和防滑垫被配置成相对于壳体与卷轴一起旋转。 开关设置在旋转轴之外,并且可以是例如应答/结束,开/关,静音,音量,播放/停止,倒带/快进和/或进入/接受控制。 电缆卷绕装置可以结合在耳机系统中。
