Wirelessly charged electronic device with shared inductor circuitry
First Claim
1. A wearable electronic device, comprising:
- a housing having first and second sides, wherein the first side is coupled to a first end of a strap and the second side is coupled to a second end of the strap;
a touch screen display in the housing, wherein the touch screen display comprises at least one force-based component;
circuitry in the housing that is driven to produce a physical vibration that serves as an alert for an event;
wireless communications circuitry in the housing that is configured to wirelessly communicate with a portable wireless electronic device;
a battery that powers the light-emitting component, the circuitry, and the wireless communications circuitry; and
wireless charging circuitry that charges the battery using received wireless charging signals.

Abstract
An electronic device may contain an input-output device such as a speaker, vibrator, or near field communications antenna. The input-output device may include an inductor. The inductor in the input-output device may be shared by wireless charging circuitry in the electronic device so that wireless charging signals can be converted into power to charge a battery in the electronic device. A separate inductor may also be provided within an input-output device to support wireless charging. A drive circuit may supply drive signals to the input-output device such as audio signals, vibrator control signals, or near field communications output signals for external near field communications equipment. An input amplifier that is coupled across the inductor in the input-output device may be used in receiving near field communications signals.
