Apple to Add Presence Sensors to EarPods & Future Beats Headsets

On May 29, 2014, the US Patent & Trademark Office published a patent application from Apple that reveals their plans to add presence sensors to both future versions of their current EarPods and Beats Headphones. The timing of this patent coming to light is perfect in light of Apple's acquisition of Beats yesterday. Our cover graphic illustrates that Apple was thinking of applying their new technology to over-the-ear headphones. The presence sensors will be able to stop streaming media from Apple's iTunes Radio and/or Beats Music along with iTunes services such as watching TV programming or Movies the second that the user removes their earphones from their head and instantly resume play of the media whenever they're worn again.


Apple's Patent Background


Accessories such as earphones are often used with media players, cellular telephones, computers, and other electronic devices. There can be difficulties associated with using earphones. For example, a user who is using earphones to listen to streaming audio content provided by an online service may occasionally need to remove the earphones. When doing so, the user may miss content that is being played. For example, a user may not be able to manually stop audio content before removing the earphones, causing some of the content to be played without the user's full attention. Playing streaming audio content while the user is not listening is not only wasteful of the electronic device's battery life but also wasteful of cellular data usage, of which the user may only be allotted a certain amount per month.


Apple Invents New Sensors for Future EarPods


Apple's invention relates to electronic device accessories like Apple's EarPods that may be provided with the ability to sense the presence of external objects. For example, an earphone accessory may be provided with sensing structures such as user detection sensors that can determine whether or not the earphones (i.e., the earphone speakers) are located in or on the ears of a user.


An electronic device may receive audio content from an online service provider such as an internet radio service or other online service provider. The electronic device may play the audio content for a user through a pair of earphones.


The earphones may have sensor structures that determine whether or not the ears of a user are present in the vicinity of the earphones.


Control circuitry in the electronic device may monitor the sensor structures to determine whether the earphones are in or on the ears of the user. In response to determining that the earphones have been removed from the ears of the user, the control circuitry may communicate with the online service provider.


Communicating with the online service provider may include sending media streaming control commands to the online service provider. The media streaming control commands may include a media streaming pause command that instructs the online service provider to pause the streaming audio content in response to the earphones being removed from the ears of the user.


The audio content provided by the online service provider may include an audio advertisement. The control circuitry may send information to the online service provider indicating that the earphones have been removed from the ears of the user during the audio advertisement.




Presence Sensors Could be headed for Future Beats Headsets



Apple's patent FIG. 7 as noted above is a perspective view of illustrative over-the-ear headphones having one or more user detection sensors. A sealing member such as sealing member #80 may be a ring or layer of foam or may be any other suitable type of ear pad configured to form a seal around the user's ear to block out ambient noise.


As shown in FIG. 7, headphones may include one or more user detection sensors such as user detection sensors #82 and #84. User detection sensors may be embedded in or formed on sealing members and may be configured to detect the presence and absence of a user's ears in the vicinity of the speaker housings. The user detection sensor may be embedded in or formed on the headband portion #78 and may be configured to detect the presence and absence of a user's head adjacent to headband.


When information from the headband sensor indicates that a user's head is not present, the headphones can conclude that the user is not wearing headphones. When information from the sensor indicates that a user's head is present, the device can conclude that the user is wearing headphones.


The user detection sensors may be temperature sensors, pressure or force sensors, capacitive sensors, acoustic-based sensors, switch-based sensors (e.g., sensors formed form mechanical switches that are actuated when a user's ear or head is present or absent), or any other suitable type of sensor configured to detect the presence and/or absence of a user's ear.


Apple further notes that other suitable actions that may be taken by the device in response to the user removing the earphones from the user's ears include: pausing, stopping, or muting the media playback, adjusting the playback volume (audio signal drive strength), closing the application on the device that is running the online service that is providing the media, and/or sending user data to the online service (as examples).
