Abstract: A device includes a battery that is operable to power the device. A power generating mechanism includes a diaphragm that generates power when the diaphragm vibrates. The diaphragm vibrates in response to force being exerted upon the diaphragm. Control circuitry of the electronic device utilizes the generated power to charge the battery. In some implementations, the power generating mechanism includes a force focusing guide that directs and/or focuses the force onto the diaphragm. In various implementations, the power generating mechanism may includes a wire coil that moves with respect to a magnet when the diaphragm vibrates, causing power to generate within the wire coil. In various other implementations, the power generating mechanism includes a piezoelectric element that is positioned adjacent to the diaphragm and is compressed and/or decompressed by vibration of the diaphragm, causing power to generate within the piezoelectric element.
