Electronic devices having shared coil structures

Abstract:

An electronic device may have a housing, a battery, a conductive coil, near-field communications circuitry, amplifier circuitry, and wireless charging circuitry. The housing may have a housing wall. The conductive coil may be adhered to the housing wall. The conductive coil may be coiled around a magnet. The amplifier circuitry may drive audio signals and/or haptic signals onto the conductive coil that cause the conductive coil to vibrate the housing wall. The near-field communications circuitry may convey near-field communications signals through the housing wall using the conductive coil. The wireless charging circuitry may receive wireless power for charging the battery through the housing wall using the conductive coil. If desired, the conductive coil may include a first set of windings that lie within a surface extending along the housing wall and/or a second set of vertically-stacked windings that extend away from the housing wall.
