Zusammenfassung:A hearing device 105 configured to receive wireless power, comprising a charging circuit 225 that has a charging coil 250, where the charging coil is at least partially wrapped around a speaker 255 for the hearing device, and a ferrite spacer disposed between the charging coil and the speaker. The charging circuit can regulate wireless power received by the charging coil and supply power to the hearing aid (e.g., to charge its battery or power components of the hearing device). A charging coil is generally a metal (e.g., copper, iron, or composite metal} that is configured to receive wireless power. The device may also comprise a rechargeable battery 220, and an antenna 245, switch 240 (for example a button or user control), and a microphone 235. The ferrite spacer may for a removable sleeve, or may comprise adhesive between the spacer and the speaker.
