Abstract
The combined charge coil and audio speaker coil assembly (30) includes a single coil (32) which acts as a charging coil for a battery charging circuit and as an audio speaker coil, in a personal care appliance. An audio speaker membrane (42) is mounted to produce audio sounds when activated. A magnet (40) is included for the audio speaker and the single coil is mounted to the speaker membrane for driving the membrane in response to a drive signal. Electrical con- tact members (50, 52) for the coil are connected to receive a driving signal to move the membrane to produce an audio sound and to a recharging circuit (34) for recharging of the appliance batteries (16).
