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.
