Earphones with ear presence sensors
First Claim
1. An electronic device, comprising:
- a housing configured to be placed in a user'"'"'s ear;
a speaker mounted in the housing;
a touch sensor on the housing;
a microphone in the housing; and
a light-based sensor attached to the housing, wherein the light-based sensor comprises a light source and a light detector, wherein light emitted by the light source is reflected off of the user'"'"'s ear and onto the light detector, and wherein audio playback through the speaker is paused in response to an amount of light that is reflected off of the user'"'"'s ear and onto the light detector.

Abstract
An electronic device may be coupled to an accessory such as a pair of earphones. The earphones may have ear presence sensor structures that determine whether or not the ears of a user are present in the vicinity of the earphones. The earphones may contain first and second speakers. When both the first and second speakers are located in the ears of the user, the electronic device may perform functions such as playing audio content. When one of the speakers has been removed from the ears of the user while the other of the speakers remains in the ears of the user, the electronic device can take actions such as pausing the playback of audio content, switching from stereo to monophonic playback, or stopping the playback of content. Suitable actions such as increasing audio drive strength may be taken when both speakers have been removed from the ears.

5. An earphone configured to receive input from a user, the earphone comprising:
-
a housing; a speaker in the housing; storage and processing circuitry that includes at least one integrated circuit in the housing; an input component in the housing that receives the input from the user and that adjusts audio playback through the speaker based on the input; a microphone in the housing; a light-based sensor in the housing, the light-based sensor comprising a light source that emits light onto the user and a light detector that receives at least a portion of the light that is reflected off of the user; and a mechanical sensor in the housing, wherein audio playback through the speaker is adjusted based on sensor data from the mechanical sensor and the light that is reflected off of the user and received by the light detector. - View Dependent Claims (6, 7, 8, 9)

10. Earphones comprising:
-
a speaker; storage and processing circuitry comprising at least one integrated circuit; a touch sensor that receives user input, wherein the touch sensor is a capacitive touch sensor, and wherein the storage and processing circuitry adjusts audio playback through the speaker in response to the user input; a light-based sensor comprising a light source that emits light onto a user'"'"'s ear and a light detector that receives at least a portion of the light that is reflected off of the user'"'"'s ear; and a mechanical sensor, wherein audio playback through the speaker is adjusted based on sensor data from the mechanical sensor and the light that is reflected off of the user'"'"'s ear and received by the light detector. - View Dependent Claims (11, 12)
