- Ear-fitting headphones are known to fall out of a wearer's ear from time to time.
- ear-fitting headphones are particularly susceptible to fall out of the wearer's ear(s) when exercising, dancing, or in crowded places where they may be accidently knocked out of the ear by another person.
- Another cause of ear-fitting headphones being accidentally removed from a wearer's ear is when the wearer has fallen asleep whilst using the ear-fitting headphone.
- the problem is particularly undesirable when wearing wireless headphones as a single ear-fitting headphone is neither attached to the other headphone or to a user device that provides the audio, such as a mobile phone or music player. This can result in the wearer losing the ear-fitting headphone.

- Figure 1 shows schematically an example of a pair of ear-fitting headphones connected to a user device.
- headphone as used herein is used as a generic term for a small loudspeaker driver worn on or around the head over a user's ear or directly within the user's ear.
- headphone covers on the one hand, “circumaural headphones” and “supra-aural headphones”, and on the other hand, “ear-fitting” headphones.
- circumaural and “supra-aural” headphones are used herein to mean headphones that use a band over the top of or around the side of the user's head to hold the loudspeakers in place.
- Ear-fitting headphone is used herein to mean a headphone that does not use a band to hold the loudspeakers in place.
- Ear-fitting headphones as used herein are individual loudspeakers that are connected by a wire or by a wireless connection to each other and/or a user device.
- Ear-fitting headphones as used herein include “earphones” and “earbuds”.
- earphones (or “in-ear headphones”) is used herein to mean headphones that are inserted directly into the ear canal.
- earbuds is used herein to mean headphones that are placed into the (outer) ear and rest outside of the ear canal, typically being held in place by the concha ridge at the centre of the outer ear.
- Ear-fitting headphones including in-ear headphones, earbuds, earphones, etc. are often small and discreet. Ear-fitting headphones can be connected to an audio source device over a wired or wireless connection. Due to their small nature, and for wireless ear-fitting headphones in particular, such headphones are likely to become lost if they are accidentally removed from a wearer's ear(s) without the wearer noticing. The likelihood of the user not realising that an ear-fitting headphone has been accidentally removed from their ear is increased if the headphone is not outputting sound at the time the ear-fitting headphone is removed. In that situation, there is no change from sound being played out to the ear to sound not being played out to the ear for the user to notice.
- Examples described herein notify the wearer when an ear-fitting headphone is removed from the ear, which helps to prevent the loss of an ear-fitting headphone.
- the wearer will of course deliberately remove an ear-fitting headphone from his/her ear during use. Informing the wearer each and every time an ear-fitting headphone is removed from the ear may cause annoyance to the wearer. Some examples described herein help to avoid informing the wearer of the removable of an ear-fitting headphone when the removal is intentional or likely to have been intentional.
- FIG. 1 shows schematically an example of a first ear-fitting headphone 100 and a second ear-fitting headphone 100 (collectively a pair of ear-fitting headphones 100) connected to a user device 102.
- Each headphone 100 may be any type of ear-fitting headphone that can be placed in a user's (outer) ear.
- each ear-fitting headphone 100 may be an earbud that sits directly outside the user's ear canal.
- each headphone 100 may be an earphone that is placed directly into the user's ear canal.
- Each ear-fitting headphone 100 has a loudspeaker or other driver 104 for outputting sound to the user.
- the ear-fitting headphone 100 also has at least one capacitive sensor 106.
- the ear-fitting headphone 100 to the left has two capacitive sensors 106 and the second ear-fitting headphone 100 to the right 100 has a single capacitive sensor 106.
- the capacitive sensor(s) 106 may generate an electric field and detect nearby objects by sensing whether the field has been disrupted.
- the capacitive sensor 106 may have two "plates" and detect an object that is conductive or that has a different dielectric property from air, like a human ear or finger. That is, a change in capacitance occurs when an object interacts with the material between the plates. The object does not have to intrude into the capacitive sensor 106 itself to cause a change in capacitance since the capacitive sensor's electric field extends into the environment surrounding the capacitive sensor 106.
- the capacitive sensor 106 may have a single plate. In that case, an object (such as a finger or ear) acts as a second plate. A change in capacitance of the capacitive sensor 106 will be caused when a finger or ear comes into contact with (or close proximity to) the capacitive sensor 106. Such an arrangement is common in capacitive touch sensors as used in for example many touch screen devices.
- the capacitive sensor 106 may be made from a metal, including for example copper or indium tin oxide.
- the capacitive sensor 106 may appear (relatively) transparent to the human eye.
- the ear-fitting headphone 100 may optionally have additional capacitive sensors.
- the ear-fitting headphone 100 may have two, three, four, or more capacitive sensors.
- Each headphone 100 may be connected to a user device 102.
- the user device 102 may be for example a media device such as a television set, a set top box, a DVD player, a Blu-Ray player, a personal computing device such as a laptop or desktop or tablet computer, a video game console, a cellular phone (including a so-called “smart phone”), a dedicated media player (e.g. an MP3 or similar player), a wearable communication device (including so-called “smart watches”), etc.
- the ear-fitting headphone(s) 100 may each be (logically and optionally physically) connected to the user device 102 over a wired or wireless connection.
- only one ear-fitting headphone 100 is (logically and optionally physically) connected to the user device 102, with the other ear-fitting headphone 100 being (logically and optionally physically) connected to the first ear-fitting headphone 100 which is connected to the user device 102.
- the user device 102 has a controller 108, such as a processor, operatively coupled to a user interface 110 of the user device 102.
- the user interface 110 may be for example a display in the form of a screen for receiving inputs from the user.
- the user interface 110 may comprise a touch screen, or a point-and-click user interface 110 comprising a mouse, track pad, or tracker ball or the like.
- the user interface 110 is configured to present information to a user of the user device 102.
- the controller 108 is also operatively coupled to a wireless transceiver 112 for communicating via any suitable wireless medium, e.g. a radio transceiver for communicating via a radio channel (though other forms are not excluded, e.g. an infrared transceiver).
- the wireless transceiver 112 may comprise a Wi-Fi, Bluetooth, etc. interface for enabling the user device 102 to communicate wirelessly with a different user device 102. Additionally or alternatively, the wireless transceiver 112 may communicate with a different user device 102 via a wireless router or a server (not shown), for example, over a local area network such as a WLAN or a wide area network such as the internet.
- the user device 102 has an interface for connecting to the headphones 100. There may be a wired interface and/or a wireless interface for connecting to the headphones 100. Examples described herein are particularly useful in the case that the headphones 100 connect wirelessly to the user device 102.
- the or each ear-fitting headphone 100 transmits a signal representative of the capacitance of the capacitive sensor 106 to the user device 102.
- the user device 102 (specifically the controller 108) determines that there has been a change in capacitance of the capacitive sensor 106.
- the user device 102 then causes a notification to be presented at the user device 102 (e.g. a visible a notification displayed on a display screen and/or an audible a notification played out through a loudspeaker).
- the user device 102 may also transmit an audible notification to be played out through the first ear-fitting headphone 100 and/or the second ear-fitting headphone 100.
- the ear-fitting headphone 100 may itself determine that there has been a change in capacitance of the capacitive sensor 106.
- the ear-fitting headphone 100 may also transmit a notification to the user device 102 to be presented at the user device 102.
- the ear-fitting headphone 100 may cause the notification to be played out of either ear-fitting headphone 100.
- an ear-fitting headphone 100 is detected as being removed from an ear of a user.
- a change in capacitance of a capacitive sensor 106 of the ear-fitting headphone 100 may be determined. The change may be, for example, due to the ear-fitting headphone 100 no longer being in contact with the user's ear.. If the capacitance of the capacitive sensor 106 has changed over a time period by an amount greater than a threshold, the user is notified that the ear-fitting headphone 100 has been removed from the ear.
- the capacitive sensor 106 when the ear-fitting headphone 100 is worn by the user, the capacitive sensor 106 will have a first capacitive value and, when the ear-fitting headphone 100 is removed from the ear, the capacitive sensor 106 will have a second capacitive value.
- the change in capacitance of the capacitive sensor 106 may be caused by the change in the dielectric constant of the material between the plates of the capacitive sensor 106.
- human skin has different dielectric characteristics from air. Therefore when the ear-fitting headphone 100 is in the ear of the user, the dielectric constant of the capacitive sensor 106 is influenced by human skin.
- the dielectric constant of the capacitive sensor 106 When the ear-fitting headphone 100 is removed from the ear of the user, the dielectric constant of the capacitive sensor 106 is no longer influenced by human skin and therefore the capacitance of the capacitive sensor 106 will change.
- the user may only be notified if the ear-fitting headphone 100 has been accidentally removed from the ear (that is, not deliberately by the user). For example, if within the time period, the user removes the ear-fitting headphone 100 from the ear (e.g. to readjust the position of the ear-fitting headphone 100 in the ear) but subsequently returns the ear-fitting headphone 100 to the ear, the capacitance of the capacitive sensor 106 will not have changed by an amount greater than a threshold.
- the capacitance of the capacitive sensor 106 will not change by an amount greater than the threshold and therefore the user will needlessly not be notified that the ear-fitting headphone 100 has been removed from the ear.
- the time period for determining if the change in capacitance of the capacitive sensor 106 breaches the threshold may be user defined.
- the time period may be set to ensure the user has enough time to remove an ear-fitting headphone 100 from the ear and replace the ear-fitting headphone 100 in order to readjust the ear-fitting headphone's position.
- the time period may also be set to ensure the user has enough time to return the ear-fitting headphone 100 to the ear upon realising that the ear-fitting headphone 100 has been accidentally removed from the ear.
- the time period may be a few seconds, such as in the range of three to five or ten seconds or so.
- the threshold may be set (e.g. by the user or the manufacturer) such that a change in capacitance due to the capacitive sensor 106 going from being in contact with human skin to air will change by an amount greater than the threshold.
- the capacitive sensor 106 may be placed on the side of the ear-fitting headphone 100 that faces the user when the ear-fitting headphone 100 is worn by the user.
- An advantage of the capacitive sensor 106 being on the inner side of the ear-fitting headphone 100 is that it increases the likelihood of a change in capacitance when the ear-fitting headphone 100 is removed from the ear, e.g. due to the change in contact with skin to air. That is, it is more likely that the capacitive sensor 106 is in contact with user's the ear during use.
- the change when looking for a change in capacitance of the capacitive sensor 106, the change may be determined by comparing the capacitance at different times, i.e. from one time instant to another. That is, the capacitance of the capacitive sensor 106 at the first time instant (e.g. at the start of the time period) is compared to the capacitance of the capacitive sensor 106 at the second time instant (e.g. at the end of the time period). The user will be notified that the ear-fitting headphone has fallen out of the ear if the difference in capacitance between the two time instants is greater than the threshold.
- the ear-fitting headphone 100 may be in the user's ear (with a capacitance value determined at least in part by human skin) and at another time instant the ear-fitting headphone 100 may have fallen to the ground (with a capacitance value at least in part determined by air).
- the change is determined by comparing the capacitance of the capacitive sensor 106 with a capacitance of a capacitance sensor 106 of a second ear-fitting headphone 100 in the user's other ear. If the two ear-fitting headphones are in the user's ears, their capacitance values would be similar (or within a small threshold of each other). If the first ear-fitting headphone 100 is removed from the user's ear, the capacitance of the ear-fitting headphone 100 will differ from that that of the second ear-fitting headphone 106.
- the (inner) capacitive sensor 106 will come into contact with (or very close proximity to) the user's skin.
- the capacitance of the two ear-fitting headphones 100 will be similar.
- the capacitance will change from the initial value due to no longer being in contact with the user's skin. The user is therefore notified that the ear-fitting headphone 100 has been removed.
- An advantage of this is that the change in capacitance will only be greater than the threshold if something happens to one ear-fitting headphone 100 but not the other. Therefore the user will not be unnecessarily notified if they intentionally take both headphones 100 out of their ear.
- the ear-fitting headphone(s) 100 may have a second capacitive sensor 106.
- the second capacitive sensor 106 may be placed on the side of the ear-fitting headphone 100 that faces away from the user when the ear-fitting headphone 100 is worn by the user.
- the second capacitive sensor 106 may be on the opposite side of the ear-fitting headphone 100 compared to the (first) capacitive sensor 106.
- the second capacitive sensor 106 may be on either side of the ear-fitting headphone 100, i.e. between the inner and outer facing sides of the ear-fitting headphone 100.
- Some examples may include determining a change in capacitance of the second capacitive sensor 106 of the ear-fitting headphone 100. Rather than notifying the user if the change in capacitance is greater than a threshold, the user will only be notified if the change in capacitance is less than a threshold.
- An option for determining the change in capacitance may involve comparing the capacitance of the second capacitive sensor 106 at one time instance and another time instance. For example, when the ear-fitting headphone 100 is in use in the wearer's ear, the capacitance of the second capacitive sensor 106 will be influenced by air.
- the capacitance of the second capacitive sensor 106 will still be influenced by air. That is, the change in capacitance over the time period will be relatively small or negligible, i.e. an amount less than a threshold. If the change is greater than the threshold due to, for example, a finger touching the capacitive sensor 106, the user will not be notified.
- An advantage with this is that the user will not be notified if the user intentionally removes the ear-fitting headphone 100.
- the user device 102 may display a notification on a display screen of the user interface 110. That is, the user interface 110 of the user device 102 is configured to present a textual or graphical notification to the user of the user device 102.
- the notification may be transmitted from the ear-fitting headphone 100 or generated and presented directly at the user device 102.
- the notification may be automatically displayed on the user device 102 in response to detecting that the ear-fitting headphone 100 has been removed.
- An advantage of this is that the displayed notification will alert the user of the accidental removal of the ear-fitting headphone 100 without the need to pause or stop the second ear-fitting headphone 100 playing out the sound that it may have been playing out at the time of removal of the first ear-fitting headphone 100.
- the user may be notified that the ear-fitting headphone 100 has been removed or fallen out by playing out a notification through the ear-fitting headphone 100 that has been removed.
- the ear-fitting headphone 100 may emit a notification sound (e.g. an alarm) at a volume loud enough for the user to hear the sound when the ear-fitting headphone 100 is not in the user's ear.
- the sound can also help the user to locate the removed ear-fitting headphone 100.
- the user may be notified that the ear-fitting headphone 100 has been removed or fallen out by playing out a notification through the ear-fitting headphone 100 that has not been removed, i.e. the second ear-fitting headphone 100 that is still in the user's ear 106.
- the notification may be spoken words or an alarm or jingle indicative of an accidental removal of the other ear-fitting headphone 100.
- the sound (e.g. a song) that was previously being played out of the ear-fitting headphone(s) 100 may be paused whilst the notification is being presented or until the ear-fitting headphone 100 has been inserted back into the user's ear.
- the sound may also be paused until the user selects to continue playing the sound, e.g. via the user device 102.
- An advantage of this is that the abrupt stoppage may serve to quickly alert the user that an ear-fitting headphone 100 has been accidentally removed.
- the user is told which ear-fitting headphone 100 has been removed or fallen from the ear. That is, the notification displayed on the display screen or played out through either ear-fitting headphone 100 to the user may contain information indicating that the ear-fitting headphone 100 that has been removed is a left or right ear-fitting headphone.
- the user device 102 determines whether a capacitance of a capacitive sensor 106 of the ear-fitting headphone 100 has changed. If the capacitance of the capacitive sensor 106 has changed over a time period by an amount greater than a threshold, the user device 102 causes a notification to be presented to the user. For example, the notification may be displayed on a display screen or played out through the (first) or second ear-fitting headphone 100.
