Headphones with orientation sensors
First Claim
1. Headphones configured to be worn in an orientation that is unreversed or reversed, comprising:
- first and second ear cups, wherein each of the first and second ear cups includes;
a speaker;
a grill with openings overlapping the speaker; and
a cushion surrounding the grill;
capacitive sensor circuitry including cushion electrodes; and
control circuitry configured to gather capacitive sensor ear images at least partly through the cushion of at least one of the first and second ear cups using the cushion electrodes.

Abstract
An electronic device such as a pair of headphones may be provided with ear cups having speakers for playing audio to a user. Capacitive sensor electrodes may be used in capturing capacitive sensor ear images that are processed by a machine learning classifier to determine whether the headphones are being worn in a reversed or unreversed orientation. The capacitive sensor electrodes may include grill electrodes that overlap at least part of a speaker grill, cushion electrodes that make capacitive sensor measurements through ring-shaped ear cup cushions that surround the speaker grills, and ring electrodes. The ring electrodes may be formed from metal traces on a flexible printed circuit. The flexible printed circuit may include a portion that wraps around each speaker grill and that is surrounded by a corresponding one of the cushions.
