Abstract
Various systems and methods may be used to provide charge to a battery and play audio. For example, a wireless headphone device may include one or more coils, such as a first coil which may be actuatable at an audio frequency. The first coil or a second coil may be tuned to a charging frequency to receive a charge (e.g., via induction) from a charging device. In an example, the wireless headphone device may be a true wireless headphone device. In an example, the true wireless headphone device includes a single coil, which is actuatable to play sound as well as receive a charge at a charging frequency.
