Electronic devices with orientation sensing

Headphones that play audio into left and right ears of a user, the headphones comprising:

• left and right ear cups having respective left and right speakers that respectively play first and second audio into the left and right ears of the user in an unreversed configuration and that respectively play the first and second audio into the right and left ears of the user in a reversed configuration;
• sensors on inner surfaces of the left and right ear cups, wherein the sensors extend from an inner portion to a peripheral portion of the ear cups, the sensors overlap outer portions of the left and right ears in directions normal to the inner surfaces, the sensors include radially extending electrodes and ring-shaped electrodes that intersect the radially extending electrodes;
• control circuitry that is configured to determine whether the left and right ears of the user are respectively adjacent to the left and right ear cups by using pattern recognition operations on output from the sensors and that is configured to play audio in the unreversed configuration in response to determining that the left and right ears are respectively adjacent to the left and right ear cups and that is configured to play audio in the reversed configuration in response to determining that the right and left ears are respectively adjacent to the left and right ear cups;
• and
• capacitive touch sensors on an outer edge portion of the left and right ear cups, wherein the capacitive touch sensors are configured to receive touch input from the user, the control circuitry is configured to adjust the audio based on the received touch input, and the capacitive touch sensors are configured to detect a grip of the user in response to detecting multiple fingers and are configured to detect a finger motion of the user in response to detecting a single finger.

Headphones that are worn by a user, the headphones comprising:

• speakers;
• ear cups, wherein each of the ear cups includes a respective one of the speakers, each of the ear cups has an inner opening and a peripheral portion, and each of the ear cups has an outer edge portion;
• capacitive touch sensors with first capacitive touch sensor electrodes located on inner surfaces of the ear cups and radially extending electrodes that intersect the first capacitive touch sensor electrodes, wherein each of the first capacitive touch sensor electrodes has a ring shape that surrounds one of the speakers, wherein the first capacitive touch sensor electrodes and the radially extending electrodes extend from the inner opening to the peripheral portion, and wherein the capacitive touch sensors gather information on a shape of ears of the user and detect whether the peripheral portion of the ear cups are in contact with the ears of the user;
• and
• additional capacitive touch sensors on the outer edge portion, wherein the additional capacitive touch sensors are configured to detect a grip of the user in response to detecting multiple fingers and are configured to detect a finger motion of the user in response to detecting a single finger.
