Sonicare

Sonicare is the brand name of an electric toothbrush produced by Philips.

The brush head vibrates at hundreds of times per second, with the latest models at 31,000 strokes per minute (260 Hz). Rather than connecting to its charger with conductors, it uses inductive charging—the charger includes the primary winding of the voltage-reducing transformer and the fat handle of the brush includes the secondary winding. The replaceable head is also driven magnetically.
