FIELD

This relates generally to electronic devices, and, more particularly, to wearable electronic devices.

BACKGROUND

Electronic devices such as headphones may be worn by people who desire to listen to audio content. Headphones may not, however, be sufficiently comfortable for napping or wearing for long periods of time.

SUMMARY

A system may include a wearable electronic device and an associated portable electronic device or other host device such as a cellular telephone or computer. The wearable electronic device may gather biometric data from a user while playing audio for the user with speakers or other audio transfer components (e.g., bone conduction transducers that play audio for the user via bone conduction). Biometric data gathered with the wearable electronic device may be transferred to the host device so that reports on the user's biometric data may be displayed for the user.

The wearable electronic device may be formed from a layer of fabric. The fabric may have opposing first and second ends that are configured to receive a user's ears while the fabric covers the user's eyes. The ends may have ear openings with triangular edge portions that receive the user's ears. Tragus openings may be formed in the fabric to accommodate the tragus portions of the user's ears. A soft central portion of the fabric between the ends may overlap the user's eyes. Light sources may be placed within the central portion to provide illumination for the user's eyes.

The wearable electronic device may have control circuitry that receives power from a power source. Sensors may be used to gather sensor information such as biometric sensor information. The sensors, control circuitry, and power source may be mounted in a stiff edge portion of the fabric. The stiff edge portion of the fabric may have an elongated strip shape and may extend along an upper edge of the central portion of the fabric. Stiffener structures that are between inner and outer layers of the fabric may be used to support the speakers.
