A wearable electronic device such as an earbud, wristwatch, or other device may be provided with a skin sensor. The skin sensor may use optical measurements to detect the presence of skin adjacent to the electronic device. The sensor may have first and second light-emitting devices such as infrared devices that emit light at respective first and second infrared light wavelengths. Reflected light is monitored by a photodetector. Control circuitry can initiate or pause audio playback or take other actions in response to determining from the reflected light measurements that skin is present. The sensor may have a thin-film interference filter or other optical structure that overlaps the first and second light-emitting devices to narrow the angular spread of light emitted from the skin sensor. This reduces tilt sensitivity and helps enhance skin sensor accuracy.

Electronic devices with skin sensors

A portable acoustic device comprising: a device housing that defines an internal cavity, the device housing comprising a speaker housing portion and a stem portion extending away from the speaker housing portion; a first acoustic port formed through a wall of the speaker housing; an audio driver disposed within the speaker housing portion and aligned to emit sound through the acoustic first port; a battery disposed within the speaker housing portion and positioned an opposite side of the audio driver than the acoustic port; an antenna disposed in the stem; a user input region disposed along the stem; and a system in a chip disposed in the stem, the system in a chip comprising: a processor that controls operation of the portable wireless acoustic device, charging circuitry, an accelerometer, a wireless communication controller, support components for the antenna and support components for the user input region.
