[0002] This application claims priority to U.S. Provisional Patent Application No. 63 / 366,403, filed on June 14, 2022, entitled “ELECTRONIC CHARGING DEVICE AND USER INTERFACE,” the entire disclosure of which is hereby incorporated by reference into this document. Technical Field

[0003] The described embodiments relate generally to electronic devices. More particularly, the present disclosure relates to electronic charging devices and user interfaces. Background Art

[0004] Advances in portable computing have enabled wearable devices, such as wireless headphones, to be wirelessly connected to one or more other electronic devices. A user can listen to the audio output from these other electronic devices through the headphones. Wireless headphones are typically small and lightweight, allowing a user to conveniently wear the headphones in or on the user's ears without cumbersome. However, the small form factor of the headphones may limit the space available on the headphones for incorporating user input features and audio control functions.

[0005] Therefore, there is a need for devices, systems and methods to increase user input and control functionality for wireless headsets and associated devices. Summary of the invention

[0006] The present disclosure relates to electronic devices. In particular, the present disclosure relates to electronic devices having user interface features.

[0007] According to one example of the present disclosure, an electronic device includes: a housing having a cavity configured to receive an earbud; an input device configured to generate a signal in response to detecting a user input; and a circuit coupled to the input device. The circuit may be configured to detect the signal and, in response to detecting the signal, transmit an instruction to the earbud to change at least one of a source or a perceived location of audio content output at the earbud.

[0008] In one example, the input device may also be configured to generate a graphical user interface. In one example, the graphical user interface includes a user-selectable icon corresponding to an audio source, and the audio source includes at least one of a music application, a calendar application, an email application, a messaging application, or a weather application. In one example, the input device may include a capacitive touch surface. In one example, the user input may include a gesture applied in a direction along the capacitive touch surface. In one example, in response to detecting a signal, the input device transmits an instruction to the earbud to change the perceived position of the audio content output at the earbud, and the direction corresponds to the perceived source position of the audio content. In one example, the instruction changes the perceived source position.

[0009] In one example of the present disclosure, an electronic system includes: a case defining an outer surface and including a cavity configured to receive an electronic device; and a display device. The display device is configured to generate a first user interface at the outer surface and generate a second user interface in response to detecting a user input at the outer surface.

[0010] In one example, the first user interface includes a graphical user interface. In one example, the first user interface includes an audio user interface. In one example, the first user interface includes a virtual user interface. In one example, the case includes a capacitive touch surface that at least partially defines a user interface area of ​​the outer surface, and the electronic device includes earplugs. In one example, the user input includes a gesture input. In one example, the gesture input includes a touch input at the capacitive touch surface. In one example, the touch input contacts the capacitive touch surface at a location corresponding to a user-selectable icon of the first user interface, and the second user interface includes a second user-selectable icon.

[0011] In one example of the present disclosure, a head-mounted display may include: a processor; a memory; and a program stored in the memory, the program including instructions that, when executed by the processor, cause the head-mounted display to display a virtual user interface on an outer surface of a housing of an electronic device that defines a cavity, detect user input at the outer surface while displaying the virtual user interface, and change the virtual user interface in response to detecting the input.

[0012] In one example, the virtual user interface virtually corresponds to a user interface area defined by an outer surface of the electronic device. In one example, the user interface area of ​​the outer surface includes a capacitive touch surface. In one example, displaying the virtual user interface includes displaying a first user-selectable icon, and changing the virtual user interface includes displaying a second user-selectable icon. In one example, the cavity is shaped to receive an earplug. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following will specifically refer to the representative embodiments and examples illustrated in the accompanying drawings. However, the following description is not intended to limit the embodiments to a preferred embodiment. On the contrary, it is intended to cover alternative forms, modifications and equivalent forms that may be included in the essence and scope of the embodiments defined by the appended claims.

[0037] The present disclosure relates to electronic devices. Specifically, the present disclosure relates to electronic charging devices with user interface features. In one example, the present disclosure includes an electronic charging device having a housing defining an internal volume and an external surface. The electronic device may also include a cavity and a charging system disposed within the internal volume and electrically connected to the cavity. In one example, the electronic device also includes a user interface area, which in some examples may include a touchpad defining a portion of the external surface. In some examples, the housing may form the user interface area.

[0038] In this example, the electronic charging device can be a charging case for wireless headphones (also referred to herein as earbuds). When one or more of the earbuds are not in use, the charging case can be used to store and charge the earbuds. During use, the earbuds can be removed from the charging case and placed in or on the user's ears to listen to audio. In one example, the charging case itself can facilitate a wireless connection between the earbuds and one or more other devices that stream or send audio. When the earbuds run low on power or when the user is done using the earbuds, the user can remove the earbuds and place them back in the charging case.

[0039] Some earbuds may include user input components, such as buttons or capacitive touch sensors, that enable the user to control the audio being listened to at the location of the earbud itself. For example, an earbud may include a capacitive touch sensor that registers taps or presses of the user's hand and / or finger on the earbud. Various combinations of taps or touches of the earbud itself can pause the audio input, increase or decrease the volume, turn it on, turn it off, etc. Earbuds and other wireless headphones can be designed to have a small form factor so that the user can wear the earbuds conveniently and comfortably. However, this small form factor limits the available space for including control input functions or other user interface features, such as the surface area of ​​the earbud itself.

[0040] Advantageously, the user interface area of ​​the charging case described herein can be used by a user to input control commands for controlling the earbuds or the audio sent to the earbuds. Such a user interface area located in the charging case of the earbuds provides increased surface area or space to replace or supplement the surface area or space of the earbuds themselves to include sensors, buttons, or other interface components that expand user input functionality, user interface output, and control functionality.

[0041] For example, at least some of the user interface areas of the electronic charging device and input device described herein may include one or more capacitive touch surfaces configured to receive gesture control from the user. For example, when wearing earplugs and listening to audio content, the user can slide a finger on the user interface area of ​​the charging box in a specific direction, motion path, or for a specific duration to indicate any number of controls to manipulate the audio being listened to through the earplugs. In one example, the user can slide left or right to move back and forth from one track to another. In another example, the user can slide a finger in a circular motion on the user interface area to indicate a volume change. The surface area provided by the user interface area described herein can therefore receive a user touch gesture as a command input to control the audio content output by the earplug. As used herein, the term "gesture", "contact gesture", "touch gesture" or other terms including "gesture" may include any path, motion or contact profile of a user's finger when contacting the user interface area. Gestures may include direction, shape, duration, pressure, or other contact characteristics between a user's finger or hand and the user interface area. For example, a gesture may include a sliding path in any direction, a shape such as a circle, triangle, rectangle or other shape, a tap, a hard press or a soft press, or any combination thereof as formed by the path of a finger along the area and as detected by the area.

[0042] The foregoing examples of gesture controls and their effects on audio listened to through the earbuds are given as non-limiting examples only. It should be understood that the user interface area of ​​the electronic charging and input devices described herein can be configured to record any gesture of any path, direction, shape, or combination thereof. The larger surface area of ​​the charging case provides higher resolution for more complex and diverse user input gesture-related commands. In general, the user interface features of the electronic charging and other input devices described herein, including the user interface area and touchpad, expand the available surface area that can be used to receive user control inputs, which in turn expands the number and variety of controls and user inputs available to the user beyond the number and variety available only on the earbuds themselves.

[0043] In addition to the expanded control functions described above, the electronic charging and input devices described herein reduce the frequency of interaction between the user's hands or fingers and the earbuds themselves. When a user controls the audio output of an earbud, the examples of the electronic input devices described herein can provide him or her with a more convenient interaction point. For example, the electronic charging input device can be configured to be placed in the user's hand / or pocket so that the user can touch the charging device near a location where the user's hand can be stationary to control the audio output or other functions of the earbud. In this way, the user does not need to repeatedly reach to his or her ear at the earbud to control the audio output.

[0044] The electronic input devices described herein (such as earbud charging boxes) can be used to provide extended user output functionality of audio devices (such as earbuds). For example, the electronic input devices of the present disclosure can include visual, audio, or tactile outputs to relay information to the user.

[0045] Additionally, in at least one example, the electronic input devices described herein may include additional components, such as processors, memory components, antennas, proximity sensors, or other components that expand the earbud control functionality and features. Such components may enable the electronic input device to communicate with one or more other electronic devices, such as other computing devices that include audio outputs. The electronic input devices of the present disclosure may be configured to advantageously control which device is connected to the earbuds, such that a user may seamlessly switch from receiving audio output from one device to receiving audio output from another device.

[0046] Wireless headphones currently on the market can generally be considered as accessories to other devices to which they are connected. For example, wireless headphones can be considered as an accessory product for mobile phones, where the headphones have limited ability to receive audio controls. That is, in many cases, the audio streamed to the headphones by the mobile phone is still largely controlled using the user interface of the phone. Therefore, the use of the headphones themselves is at least partially dependent on the mobile phone, and in this way can be considered an accessory. However, wireless headphone components (such as the earbuds and charging boxes described herein) can be configured as independent electronic devices that utilize input and control interfaces at the box itself. In this way, in at least some examples, the audio devices and systems described herein can be used to create an immersive lifestyle device, which can include music streaming, message and calendar notifications, driving directions, etc., without relying on or being attached to another device.

[0047] The following references Figure 1 to Figure 1 5 to discuss these and other embodiments. However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these figures is for illustrative purposes only and should not be construed as limiting. In addition, as used herein, a system, method, article, component, feature, or sub-feature comprising at least one of a first option, a second option, or a third option should be understood to refer to a system, method, article, component, feature, or sub-feature that may include one of each listed option (e.g., only one first option, only one second option, only one third option), multiple of a single listed option (e.g., two or more first options), two options at the same time (e.g., one first option and one second option), or a combination thereof (e.g., two first options and one second option).

[0048] Now turning to the attached figure, Figure 1 A schematic diagram of an electronic input device 100 is illustrated, which is further referred to herein as device 100. In at least one example, device 100 includes a housing 102 that at least partially defines an interior volume 104 and an exterior surface 106. Additionally, at least one example of device 100 includes a cavity 108. Cavity 108 can be disposed within interior volume 104 and can be at least partially defined by one or more housing interior surfaces 110. Figure 1 In the example of FIG. 1 , the device 100 also includes a charging system 112 disposed within the interior volume 104. The charging system 112 can be electrically connected to the cavity 110 via one or more electrical connections, such as wires or other charging circuits 114.

[0049] In at least one example, device 100 includes a user interface area 116 that defines at least a portion of exterior surface 106. In at least one example, housing 102 can define at least a portion of user interface area 116. User interface area 116 can take many forms, and is generally configured to receive touch input when contact is made at exterior surface 106 of device 100 defined by user interface area 116. In one example, user interface area 116 includes a touch pad, such as a capacitive touch pad having a surface area that at least partially defines exterior surface 106.

[0050] In at least one example, the charging system 112 can be configured to deliver current to the cavity 108 such that the current is carried to one or more housing interior surfaces 110 defining the cavity 108. In this manner, an object received into the cavity 108 and in contact with the housing interior surface 110 electrically connected to the charging system 112 can be charged. Figure 2A and Figure 2B As shown, device 200 includes cavity 208 configured to receive earplug 218. Figure 2A The earplug 218 is illustrated separated from the device 200, where the arrow indicates that the earplug 218 can be inserted into the cavity 208. Figure 2B As shown, the earbud 218 can be received in the cavity 208 so that the earbud 218 contacts at least a portion of one or more housing inner surfaces 210 that define the cavity 208. In this way, when the earbud 218 is received in the cavity 208, the charging system 212 can deliver current to the earbud 218 via the charging circuit 214, which contacts the housing inner surface 210, and the current is delivered to the housing inner surface through the charging system 212 and the charging circuit 214.

[0051] The earbuds 218 may include one or more internal batteries (not shown) that power the earbuds 218 when the user removes the earbuds 218 from the cavity 208 of the device 200 and places the earbuds 218 on or in his or her ears to listen to the audio output from the earbuds 218. When the user is finished using the earbuds 218 or when the one or more batteries of the earbuds 218 run low on power, the user may insert the earbuds 218 into the cavity 208 of the device 200, as shown in FIG. Figure 2B As shown, to recharge one or more batteries of the earbud 218. In addition, at least one example of the charging system 212 of the device 200 includes a battery. The battery of the charging system 212 can be recharged using external power and can be configured to deliver current to the cavity 208 and thus to the earbud 218 through the charging circuit 214 for recharging.

[0052] Figure 2A and Figure 2BThe device 200 shown in FIG. 2 also includes a user interface area 216 that at least partially defines the outer surface 206 of the housing 202 . Figure 1 , Figure 2A and Figure 2B The components and features of the devices 100 and 200 shown in the drawings may be included in any other device described herein, alone or in any combination. In addition, the features and components of the devices described with reference to other figures may be combined in the drawings, alone or in any combination. Figure 1 , Figure 2A and Figure 2B In the devices 100 and 200 shown in FIG.

[0053] Figure 3 A schematic diagram of a device 300 is illustrated that includes a housing 300 and defines at least a portion of an outer surface 306. The device 300 also includes a user interface area 316, which can also define at least a portion of the outer surface 306. In one or more other examples, the size, shape, and location of the user interface area 316 can vary. In general, the user interface area 316 can provide a certain amount of surface area available for receiving touch commands from a user, which is larger than the surface area available from an earbud (such as, Figure 2A and Figure 2B That is, user interface area 316 may define an area of ​​outer surface 306 to receive a user's touch input, such as touch gestures and sliding contacts that may extend across the area specified by user interface area 316 or anywhere within the area.

[0054] Thus, in at least one example, user interface area 316 includes one or more sensors, such as touch sensors. Device 300 may include circuitry coupled to device 330 or to a processor of device 300 that may be electrically connected to one or more sensors of user interface area 316 so that, for example, when a user taps, swipes, or otherwise gestures while in contact with user interface area 316, the location and changes in location of the user's touch may be detected and identified.

[0055] exist Figure 3 In the illustrated schematic, the user interface area 316 is shown as a generally square or rectangular area centrally disposed on the housing 302 of the device 300. This configuration of the user interface area 316 is one exemplary configuration, and other examples may include two or more user interface areas 316 that at least partially define the exterior surface 306, wherein each of the plurality of user interface areas has a plurality of user interface areas that are substantially rectangular. Figure 3During use, a user can manipulate device 300 via housing 302 and touch user interface area 316 using one or more fingers, such as by tapping, sliding, or otherwise gesturing on an area of ​​outer surface 306 defined by user interface area 316. Such gestural contacts from the user's hand / or fingers can be received by device 300 and interpreted as various audio control input commands.

[0056] Thus, in at least one example, user interface region 316 includes a capacitive touch surface that defines at least a portion of exterior surface 306 of device 300. In one example, such a touch surface can be a distinct component that is separate from other portions of housing 302 but defines a portion of exterior surface 306 together with the remainder of housing 302. Alternatively, such a capacitive touch surface of user interface region 316 can be defined by housing 302 such that a defined portion of housing 102 is used to receive touch input. In this way, housing 302 can form a dielectric layer or plate of a capacitive sensor stack.

[0057] Along these lines, the user interface region 316 may include multiple components (including multiple layers) that are configured to sense a capacitance change of one or more of these layers when a user contacts a portion of the outer surface 306 of the housing 302 corresponding to the user interface region 316. In one example, the housing 302 forms a dielectric layer disposed between the skin / finger of the user during contact with the user interface region 316 and one or more conductive layers disposed inwardly from the outer surface 306 of the housing 302 (e.g., within the inner volume 304). Such layers may be configured to retain charge. In one example, such inner conductive layers of the capacitive touch sensor stack forming the user interface region 316 may include one or more conductive plates or electrodes. The sensing circuit may electrically connect such conductive layers to one or more processors within the device 300. The processor may be configured to determine a charge change of the inner conductive layer. Such a charge change may occur when the user's finger approaches or contacts the user interface region 316 at the outer surface 306 of the housing 302, wherein the user's finger acts as an oppositely charged object to be sensed.

[0058] In one or more other examples, the user interface area 316 may include one or more other types of touch sensors and components thereof. For example, the user interface area 316 may include one or more pressure sensors and components thereof, one or more resistive touch sensors and components thereof, or other touch sensor configurations and components thereof.

[0059] Additionally or alternatively, one or more examples of user interface area 316 described herein may include one or more depressible buttons defining a portion of housing 302. For example, user interface area 316 may include one or more buttons that may be pressed below a level or plane defined by outer surface 306 of housing 302. In this manner, user interface area 316 may include tactile feedback from a physical press of a button when an audio control command (such as a gesture) is input at device 300 with his or her finger or hand. At least one example of device 300 may include a combination of one or more depressible buttons and / or one or more areas defining user interface area 316, such as a capacitive sensor touch pad as described herein.

[0060] refer to Figure 3 All features and components or combinations thereof described for the device 300 shown in the drawings may be combined, alone or in any combination, with other devices described herein with reference to other figures. In addition, those features and components of the devices shown and described with reference to other figures may be combined, alone or in any combination. Figure 3 The device 300 shown in is comprised in combination.

[0061] Figure 4 Another example of a device 400 having a cavity 408 configured to receive an earbud is illustrated. The device 400 also includes a housing 402 defining an outer surface 406, wherein a user interface area 416 also defines a portion of the outer surface 406. As shown, the device 400 also includes a charging system 412 that is configured to charge the earbud received in the cavity 408. In addition, at least one example of the device 400 includes a processor 420 and an antenna 422. In at least one example, the processor 420 and the antenna 422 are disposed within the internal volume 404 of the device 400. In addition, the device 400 may also include circuitry connecting the antenna 422 to the processor 420.

[0062] One or more other examples of device 400 may include two or more processors 420 and / or two or more antennas 422 disposed at various locations within internal volume 404. In at least one example, antenna 422 is configured to send electromagnetic signals to device 400 and receive electromagnetic signals from the device. For example, antenna 422 may be configured to transmit electromagnetic signals to one or more earbuds that are separate from device 400 and used by a user. In addition, for example, antenna 422 may be configured to transmit and receive signals between device 400 or earbuds and other electronic devices (such as mobile phones or other computing devices), which may send audio signals or content to the earbuds. In response to detecting or transmitting one or more electromagnetic signals, device 400 may transmit instructions to the earbuds or other electronic devices.

[0063] Processor 420 can be electrically coupled to user interface area 416 and antenna 422 via circuitry. Processor 420 can be configured to cause antenna 422 to transmit signals to and receive signals from various other devices via circuitry based on user input received by user interface area 416, including one or more earbuds configured to be received in cavity 408. A user can enter a command via user interface area 416, such as by tapping, gesturing, sliding, or otherwise contacting user interface area 416, so that the command indicates an intended action of device 400. For example, a particular gesture input at user interface area 416 can indicate that a user wants to skip from a song being listened to through an earbud to the next song. Processor 420 can be configured to recognize the input command and cause antenna 422 to transmit one or more signals to communicate with device 400 or an associated earbud (such as a mobile phone) from which the earbud streams music. As another example, a user can enter a gesture or other touch command at user interface area 416 to indicate an intention to start or stop sending audio content to an earbud. Processor 420 may be configured to recognize any kind of such command at user interface area 416 and cause antenna 422 or any other component of device 400 to perform the action or function desired by the user.

[0064] It will be appreciated that the processor 420 may recognize any number of contact gestures, swipes, taps, or other touch commands entered by a user at the user interface area 416. The processor 420 may therefore be configured to execute any such command entered by the user at the user interface area 416. Executing such a command may include causing the antenna 422 to transmit or receive signals with one or more other devices, or causing one or more other components of the device 400 to execute the command. As non-limiting examples, other commands that may be entered by the user include skipping tracks, speeding up or slowing down audio input, switching from one audio stream to another, connecting or switching to or from various other devices providing audio streams, increasing or decreasing volume, or any other audio control command.

[0065] Antenna 422 may include one or more components configured to transmit and receive electromagnetic signals, including digital audio content signals, etc. For example, antenna 422 may include multiple antenna modules, including Bluetooth modules and circuits, ultra-wideband stacks, or other transmitter-receiver modules or combinations thereof.

[0066] refer to Figure 4 All features and components or combinations thereof described for the device 400 shown in the drawings may be combined, alone or in any combination, with other devices described with reference to other drawings. In addition, those features and components of the devices shown and described with reference to other drawings may be combined, alone or in any combination. Figure 4The device 400 shown in is included in combination.

[0067] Figure 5 A schematic diagram of another example of a device 500 is illustrated, the device including a cavity 508 configured to receive one or more earbuds, a user interface area 516, a charging system 512, a processor 520, and an antenna 522. In at least one example, a circuit may be coupled to the device 500 that electrically connects the antenna 522 to the processor 520. In addition, at least one example of the device 500 may include one or more memory components 524 or one or more proximity sensors 526. The processor 520 may also be electrically connected to or otherwise electrically communicate with the memory component 524 and the proximity sensor 526. The device 500 with the memory component 524 may be configured to store data, such as audio content or other data associated with a mobile device application, such as message data, email data, an audio content library including music and other tracks, etc. In this way, the device 500 can access the content at the memory component 54 and stream the content to the earbuds via the processor 520, so that the antenna 522 sends the data from the device 502 to the one or more earbuds being used by the user.

[0068] Advantageously, the device 500 including the memory component 524 can be used as a standalone audio content device for streaming audio content to a user via earbuds without being connected to or as an accessory to other devices such as a phone, computer, digital music player, etc. For example, audio can be downloaded and stored directly on the memory component 524 of the device 500, and the processor 520 can be configured to stream the content stored on the memory component 524 to one or more earbuds via the antenna 522 or other components. In this example, when the content from the memory component 524 is sent to the earbuds, the user interface area 516 can be used to control the content from the memory component.

[0069] Figure 5 The components and features of the device 500 shown in FIG. 5 (such as the memory component 524 and the proximity sensor 526) may be included in any of the devices described herein with reference to other figures. In addition, the features and components of other devices described herein with reference to other figures may be included in the devices described herein with reference to other figures, either alone or in combination with each other. Figure 5 The device 500 is described.

[0070] Figure 6A user is shown, wherein device 602 is arranged in the user's trouser pocket, and one or more earplugs 618 are arranged at or on the user's ear. As described above, the size and shape of device 600 can be configured to be conveniently placed in a pocket, as shown, or placed in any other clothing pocket, wallet or bag worn by the user. In some examples, the user can choose to keep device 600 in his or her hand during use. Advantageously, the user can choose to most conveniently keep or store device 600 to quickly access the user interface area of ​​device 600, so as to easily control the audio streamed to earplug 618. In addition, as described herein, device 600 can include a memory component, from which device 600 can stream audio content to earplug 618 without any wireless connection or other connection to another device (such as a mobile phone). In other examples, the user can also carry one or more mobile or wearable computing devices wirelessly connected to earplug 618 and / or device 600, such as a mobile phone, an electronic watch, or a tablet computer and a laptop computer. In such examples, device 600 may be configured to connect earbud 618 to one or more of the other devices so that the one or more other devices can transmit audio content to earbud 618. In some examples, device 600 may include one or more antennas configured to transmit audio content from device 600 itself to earbud 618, as described herein.

[0071] As described above, the device 600 can be a charging case for the earbuds 618. That is, in addition to the other features and functions of the device 600 described above, the device 600 or the charging case 600 can also include one or more cavities for receiving the earbuds 618 and a charging system configured to charge or recharge one or more batteries of the earbuds 618. Advantageously, the charging functionality of the device 600 can be combined with other control features, components, and functions described herein (e.g., user interface areas, processors, circuits, antennas, memory components, proximity sensors, etc.) in a simple and compact device.

[0072] Additionally, when a user interacts with device 600 to control the audio output of earbud 618, device 600 and other devices described herein may include one or more output features to convey information to the user. That is, in addition to the user interface areas described herein that are configured to receive command input from the user, one or more examples of devices of the present disclosure may include user interface output features and components. For example, Figure 7 A schematic diagram of a device 700 is shown that includes a housing 702 that defines an exterior surface 706, a user interface area 716, and one or more output features 728. The output features 728 are shown in dashed lines to indicate that the number, size, shape, and location of each output feature 728 may vary from one example to the next. Figure 7 Some examples of output feature locations are shown on the outer surface 706 of the device 700. Additionally, for illustrative purposes only, the output features 728 are shown as being generally rectangular or circular in shape. Figure 7 The dashed line in FIG. 7 indicating output feature 728 is provided as a general example of where one or more output features may be located on device 700 .

[0073] In one example, one or more output features 728 may include visual icons, such as lights or backlit images that can be turned on or off to relay information to the user. For example, one output feature 728 may include an envelope in the form of a backlight that indicates an email notification to the user. Once indicated by the output feature 728, the user may enter a touch command at the user interface area 716 so that the processor of the device 700 may cause an audio output of the email notification or email content to be streamed to the earbuds. In the aforementioned example of email notifications, one or more components of the device 700 (such as an antenna or other transmitter and receiver of the device described herein) may relay audio output from an email message or a notification from a separately connected device (such as a mobile phone or computer).

[0074] One or more output features 728 may include other visual or tactile outputs to notify the user of various other notifications, the status of the device 700, or other information. For example, one or more output features 728 may remind the user with a visual icon representing a received text message, an upcoming calendar event, a missed call from a connected mobile phone, or any other information relayed to the device 700 from other connected electronic devices. The output features 728 may also include one or more light indicators without a particular form of image. As shown, at least one output feature may utilize an area of ​​the outer surface 706 occupied by the user interface area 716. For example, the output feature 728 located at the user interface area 716 may include a diffuse backlight portion of the outer surface 706. In addition, any of the light-emitting output features 728 of the device 700 may include a plurality of colors that may indicate unique meanings to the user.

[0075] In response to receiving information from the output feature 728, the user may swipe or otherwise make a gesture on the user interface area 716 of the housing 702 to change the audio output of the earbud based on the information relayed by the output feature 728. Using the mail envelope example from above that may indicate an incoming email message to the user, the user may then touch or swipe on the user interface area 716 in a particular manner that causes the processor of the device 700 to switch the audio sent to the earbud to an audio reading of the content of the email. For example, the user may make a swipe gesture with his or her finger on the user interface area 716, where the direction of the swipe or gesture points to a given output feature 728. In this way, the user may indicate the output feature 728 that he or she is interested in, and the audio output of the earbud may be switched accordingly. This is an example of an interaction between a user and the device 700 that includes one or more output features 728 relaying information to the user, and the user then reacting to the information by inputting controls via the device 700 to manipulate the content of the audio received by the wirelessly connected earbud.

[0076] It should be understood that any number of output features 728 or combinations of output features 728 can convey any number of notifications, states, or other information to the user. Other interactions between the device 700 and the user can include output features 728 indicating traffic directions. Thus, if the user is listening to music via earbuds wirelessly connected to the device 700, one or more output features 728 can indicate to the user that he or she needs to listen to upcoming traffic navigation instructions. In reaction, the user can slide or gesture on the user interface area 716 so that the device 700 then interrupts the music with navigation instruction audio output at the earbud. The same process can occur for output features 728 indicating text messages, weather conditions and forecasts, news headlines, stock price updates, missed calls from mobile phones, or any other information that can be relayed to the earbuds via audio.

[0077] In addition to or as an alternative to the output features 728 of the device 700 described herein, the device 700 may include one or more tactile output features or components for interfacing with a user and tactilely communicating non-audio information from the device 700. For example, the device 700 may include a motor or other vibration generating component that may cause the device 700 to vibrate to alert a user to a state change, notification, or other output information, as described above. The vibration or other tactile feedback mechanism may be configured to provide unique motions or vibrations of the device 700, each of which conveys unique information to the user.

[0078] Figure 7The components and features of the device 700 shown in FIG. 7 (such as the configuration of the various output features 728 and the user interface area 716) may be included in any of the devices described herein with reference to other figures. In addition, the features and components of other devices described herein with reference to other figures may be included in the devices described herein with reference to other figures, either individually or in combination with each other. Figure 7 The device 700 is described.

[0079] Figures 8 to 13 Schematic diagrams showing various examples of user interface areas that can be implemented individually or in combination with each other in any of the devices described in the present disclosure. For example, Figure 8 A schematic diagram of a device 800 is shown, which may include any or all of the features and components of the other devices described herein with reference to other figures. For example, the device 800 may be configured as a charging case for earbuds. In one example, the user interface area 816 may be generally circular and may be centrally disposed on the outer surface 806 of the device 800. In at least one example, the user interface area 816 may include a capacitive touch pad surface or sensor.

[0080] exist Figure 8 In the illustrated example, the touch pad or housing 802 forming the user interface region 816 may be raised or lowered to define a plane that is different from one or more planes defined by the remainder of the housing 802 defining the outer surface 806. The transition surface 830 may form a portion of the outer surface 806 that extends between the user interface region 816 and the remainder of the housing 802. For example, in examples where the user interface region 816 includes a raised surface, the transition surface 830 may slope upward from the housing 802 to the user interface region 816. Similarly, in examples where the user interface region 816 is recessed below the remainder of the housing 802, the transition surface 830 may slope downward toward the user interface region 816. Alternatively, in examples where the user interface region 816 is substantially flush or shares a plane with the remainder of the housing 802, the transition surface 830 may form a channel or ridge.

[0081] In any case, transition surface 830 can be used to provide a physical feature that indicates to the user where the border or outer perimeter of user interface area 816 is located. In this way, if the user stores device 800 in a pocket or purse without being visible, such as Figure 6 As shown in , the user can blindly feel and locate user interface area 816 on device 800.

[0082] Fig.9A Another example of a device 900 is shown, such as a charging case for wireless earbuds. Fig.9AA schematic diagram of a device 900 is shown, which may include any or all of the features and components of other devices described herein with reference to other figures. Fig. 9B Illustrated based on Fig.9A A schematic diagram of an embodiment of the apparatus 900 is shown in side view. Fig.9A In the illustrated example, the device 900 includes two different user interface areas 916a, 916b, wherein the inner user interface area 916a is centered and is concentrically arranged with the outer user interface area 916b. Similarly, the user interface areas 916a and 916b may include one or more sensors, touch pad surfaces, or other forms of user interface areas defined herein. Transition surfaces 930a, 930b, 930c may be arranged to transition between the user interface areas 916a, 916b and the outer surface 906 of the housing 902. Transition surfaces 930a and 930b may form ridges or valleys that transition between the two user interface areas 916a, 916b. In this way, the user can feel the difference between the two user interface areas 916a, 916b on the sense of touch, without visually verifying the position where the user's finger or hand contacts the device 900.

[0083] Fig.10 A schematic diagram of a device 1000 is shown, which may include any or all of the features and components of other devices described herein with reference to other figures. For example, the device 1000 may be configured as a charging case for earbuds. Fig.10 In the illustrated example, the device 1000 may include three different user interface areas 1016a, 1016b, 1016c with corresponding transition surfaces 1030a, 1030b, and 1030c. The arrangement, configuration, and number of different user interface areas may vary from one example to another. Each user interface area 1030a to 1030c may be used separately for unique commands received through gestures, swipes, touches, taps, etc., as described herein.

[0084] Fig.11 Another example of a charging case having one or more user interface areas incorporated into an outer surface thereof is shown in FIG. Fig.11 A schematic diagram of a device 1100 is shown, which may include any or all of the features and components of other devices described herein with reference to other figures. Fig.11 Two separate and circular user interface areas 1116a, 1116b are shown with corresponding transition surfaces 1130a, 1130b, respectively.

[0085] Fig.12 and Fig.13Schematic diagrams of other examples of devices 1200, 1300 are shown, which may include any or all features and components of other devices described herein with reference to other figures. Device 1200 includes a single user interface area 1216 that is centrally disposed on device 1200 and forms an elongated shape or strip. Fig.13 The device 1300 includes a single user interface area 1316 in the shape of a cross having a plurality of extensions around a central portion thereof.

[0086] from Figures 8 to 13 It will be appreciated from the foregoing examples of the devices shown in that any size, shape, position or configuration of one, two or more than two user interface areas may be incorporated into a device (such as an earbud charging case) to form part of the outer surface of the charging case. Each of the configurations shown may receive a touch gesture command from a user's finger or hand, including a slide, tap or any other gesture path from a user's finger. As used herein, the terms "gesture", "gesture command", "gesture touch" or other related terms may refer to the movement and position of a detected user touch, such as physical contact of a user's finger on a device described herein, on or at a user interface area of ​​the device. A user may input a gesture by touching the user interface area of ​​the device or by touching a finger or other body part and moving the finger or other body part in a path along the outer surface of the device corresponding to the user interface area. Some gestures may include a path or shape of a user's continuously moving touch. Some gestures may include a single tap or touch without moving from a certain position. Some gestures may include multiple taps or a combination of one or more single touches / taps and one or more movements or paths / shapes created by the user's touch. Therefore, the user interface area of ​​the device described herein includes a surface area large enough to accommodate such gestures.

[0087] One or more processors of the illustrated device may cause one or more other components of the device to send or receive various commands to or from wirelessly connected earbuds or other devices to control the audio output of the earbuds being used. Figures 8 to 13 Each feature or component of the device shown in the figure may be included in any other device described herein with reference to other figures. In addition, the features and components of other devices described herein with reference to other figures may be included in the reference figures alone or in combination. Figures 8 to 13 described in the device.

[0088] As mentioned above, specific reference Figure 5Device 500 shown, any device described herein may include one or more proximity sensors. One or more proximity sensors of the devices described herein may include one or more proximity sensing modules or proximity stacks, such as Bluetooth modules, multiplexed Bluetooth modules, or ultra-wideband (UWB) stacks, which may be configured to sense or detect the presence of another electronic device. For example, the proximity sensor of the device (charging box) described herein may be configured to sense when the device (e.g., charging box) is close to a mobile phone, tablet computer or other computer, or other mobile or wearable electronic device (such as an electronic watch, smart glasses, or headphones).

[0089] Along these lines, Fig.14 Device 1400 is shown used in proximity to other electronic devices. Fig.14 When using the device 1400, the device 1400 is referred to as an earbud case or simply a case. During use, the case 1400 may be close to one or more other electronic devices, such as electronic devices 1432 and 1434. For clarity, the description Fig.14 When, a non-limiting example of electronic device 1432 is a mobile phone, and a non-limiting example of electronic device 1434 is a laptop computer.

[0090] Both the mobile phone 1432 and the laptop computer 1434 can output audio content to one or more earbuds 1418 worn by the user. Fig.14 As shown, both the mobile phone 1432 and the laptop computer 1434 can send and receive signals indicated by lines 1436 and 1438, respectively, between the case 1400 and / or the earbuds 1418. In one example, the signals 1436 and 1438 can include digitally transmitted audio content. In at least one example, the signals 1436 and 1438 can include signals sent and received by one or more proximity sensors within the mobile phone 1432 and the laptop computer 1434. During use of the case 1400 and the earbuds 1418, the user can receive audio content from the mobile phone 1432 or the laptop computer 1434. However, the user may also want to switch back and forth between the audio content provided by the mobile phone 1432 and the audio content provided by the laptop computer 1434.

[0091] Advantageously, as described herein with reference to other figures, case 1400 can include one or more proximity sensors configured to sense the presence of other electronic devices. For example, a proximity sensor of case 1400 can detect the presence of a nearby mobile phone 1432 and a laptop computer 1434. Additionally, one or more proximity sensors of case 1400 can be configured to sense the distance between case 1400 and other electronic devices. For example, Fig.14As shown, the user holds case 1400 closer to mobile phone 1432 than to laptop computer 1434. In at least one example, one or more processors of case 1400 can be electrically connected to one or more proximity sensors thereof and can be configured to determine which external electronic device (mobile phone 1432 or laptop computer 1434) is closer to case 1400.

[0092] Once the relative position between the case 1400 and the mobile phone 1432 or laptop computer 1434 is determined, the case 1400 can be configured to provide the user with the option of receiving the audio output of the nearest electronic device, which is located at the Fig.14 The illustrated example includes a mobile phone 1432. For example, once the user brings the case 1400 into close proximity with the mobile phone 1432, a user interface area of ​​the case 1400 (such as the user interface areas described herein with reference to other figures and devices) may receive a touch or gesture command from the user indicating that the user wants to switch from one audio output source to another, such as from the audio output signal 1438 of the laptop computer 1434 to the output source or signal 1436 of the mobile phone 1432.

[0093] In another example, when the user brings the box 1402 closer to the laptop computer 1434 and thus further away from the mobile phone 1432, the user may choose to switch the audio content being streamed to the earbuds 1418 from the audio output signal 1436 of the mobile phone 1432 to the audio output signal 1438 of the laptop computer 1434. Likewise, the box 1400 may include one or more proximity sensors and processors that enable detection of external electronic devices and relative positions to the external electronic devices. The one or more processors may cause the box 1400 to switch the audio content being sent to the earbuds 1418 based on the relative position and one or more commands given to the box 1400 by the user via one or more user interface areas of the box 1400.

[0094] Fig.14A simple example of a box 1400 is shown that provides an easy and convenient way for the user to switch the audio content streamed to the earbud 1418 from one device to another (e.g., from a mobile phone 1432 to a laptop computer 1434). It should be understood that the box 1400 can be configured with proximity sensors, processors, and other components that enable the user to switch between more than two devices based on the proximity of the box 1400. For example, the proximity or relative position of the box 1400 and an electronic device that provides audio output (e.g., a smart speaker, a television, a desktop computer, a laptop computer and a tablet computer, an electronic watch, an electronic glasses, or any other electronic device that outputs audio content in a home, office, or other environment) provided in the user's environment can be detected. As the user moves around in his or her environment and becomes closer or farther away from these other electronic devices, the user can seamlessly and conveniently select which audio output is sent to his or her earbud by bringing the charging box of the earbud into close proximity with the selected electronic device and gesturing or otherwise touching at the user interface area of ​​the charging box to select the audio output of the electronic device.

[0095] As described above, when a user switches from the transmission of one audio content to another, the processor of the device described herein (such as an earbud charging box) can smoothly transmit the sound heard by the user through the earbuds from one audio source to another audio source. This conversion may include fade-in and fade-out between different audio sources. In one example, one audio source may be switched to the listener at a lower volume than another audio source. In another example, the volume of one audio source may be reduced but not completely eliminated when another audio source is provided. For example, notifications from other devices about text messages, emails, calendar events, etc. can slowly fade in to audibly cover the audio track that has been listened to, while the audio track is reduced or faded out in volume.

[0096] In addition to fading or volume transitions between audio sources, the charging case and devices described herein can enable the earbuds worn by the user to generate and change the spatial location of various audio content and sources provided to the user. Fig.15AAn example of a spatial audio system including two earbuds 1518a, 1518ba, 1518b is illustrated, where each earbud 1518 is located in or at a respective ear of a user 1505, as shown from a top view. In one example, the perceived position, direction, and distance of the audio content being listened to by the user can be manipulated from left to right, front to back, or above and below the user 1505 by tracking head position and orientation, and changing the audio output volume, timing, or other characteristics of the audio content output by the earbuds 1518ba, 1518b from one earbud to the other accordingly. The spatial audio bands 1540 represent a set of locations where the audio output of the earbuds 1518a, 1518b can be perceived, but not necessarily where the sound is generated. Sounds 1542, 1544, 1545, and 1546 may be produced at the locations of earplugs 1518a, 1518b such that the perception of those sounds 1542, 1544, 1545, and 1546 is localized along spatial audio band 1540, as shown in FIG. Fig. 15B Sounds 1542, 1544, 1545, and 1546 are represented by directional arrows and sound propagation waves / lines. Fig.15A Four representative example sounds 1542, 1544, 1545, and 1546 are shown with specific positions and directions of audio content from earbuds 1518a, 1518b as perceived by the user. The perceived sounds 1542, 1544, 1545, and 1546 are given as non-limiting examples only. However, one or more other examples include a spatial audio system that can generate a perceived position of the output of the earbuds 1518a, 1518b from any point along the continuous position and direction represented by band 1540.

[0097] exist Fig.15A In the example shown in , each sound 1542, 1544, 1545, and 1546 may be the same output from both earbuds 1518a, 1518b, so that the user perceives the audio output as if the user is in a central position surrounded by the sounds 1542, 1544, 1545, and 1546. Fig. 15B In at least one example shown in FIG. 1 , each sound 1542, 1544, 1545, and 1546 may be a unique input from one or both earbuds 1518a, 1518b, such as Fig. 15B , as indicated by each sound 1542, 1544, 1545, and 1546 having a different dashed line in the figure. In this example, the user may perceive multiple sounds 1542, 1544, 1545, and 1546 from different directions, as if (for example) the user is in a room with multiple sound sources from different directions, such as music from the left, a person talking on the right, another person talking in front of the user, and a car honking outside from behind. In this way, as Fig. 15BAs shown in the example of , spatial audio can be used to simulate a natural, real-world acoustic environment through audio from earbuds 1518a, 1518b.

[0098] In at least one example, when switching from one audio source to another, one or more processors of the charging case of the earbuds 1518a, 1518b may cause the earbuds 1518a, 1518b to change the perceived position or orientation of two or more different audio sources as the user switches from one source to another, as commanded by the user at a user interface area of ​​the charging case. For example, if the user is listening to music and wants to switch from one piece of music to another, the user may manipulate the interface surface (such as by swiping from left to right on the user interface area of ​​the charging case). Thus, the one or more processors of the charging case may cause the earbuds to move the first audio track from left to right along the spatial audio band 1540 (as perceived by the user) and move the second audio track from left to right onto the spatial audio band 1540. For example, as shown in FIG16C , in Fig. 15B The sound 1546 perceived from the right side of the user 1505 can move to the left along the spatial audio band 1540. When the first audio track (e.g., sound 1546) moves from the left or right, the processor of the charging box can also gradually fade out the first audio track.

[0099] Along these lines, it will also be noted that Fig. 15C The sound propagation wave lines associated with the sounds 1542, 1544, 1545, and 1546 shown in FIG. 1 may vary in number to indicate the volume level of each sound 1542, 1544, 1545, and 1546. Fig. 15B Compared with the four propagation wave lines of the sound 1542 shown in FIG. Fig. 15C In contrast, Fig. 15B Compared to the sound shown in 1544, Fig. 15C The volume of sound 1544 can be increased. The volume of each sound 1542, 1544, 1545, and 1546 can change the perceived distance at which the sound 1542, 1544, 1545, and 1546 is emitted. Thus, while spatial audio band 1540 is shown surrounding user 1505 at a certain distance, in at least one example, the distance of spatial audio band 1540 and the perceived distance of each sound 1542, 1544, 1545, and 1546 can also vary.

[0100] The perceived location of each sound 1542, 1544, 1545, and 1546 can be changed in conjunction with the volume of each sound 1542, 1544, 1545, and 1546, such as Fig. 15CAs shown in , input commands at the user interface area of ​​the charging box of the earbuds 1518a, 1518b can produce a dynamic, immersive and natural sound experience. Fig. 15C As shown in , the sound can be manipulated at the charging case so that one or more sounds 1542, 1544, 1545, and 1546 partially or completely overlap. This can be done Fig. 15C , where sounds 1544 and 1546 move to partially overlap. In this example, user 1505 can perceive two sounds 1544, 1546 from the same or similar position along the spatial audio band 1540.

[0101] The foregoing is a non-limiting example of how user touch and finger gesture commands at the user interface area of ​​the earbud charging case may be used to manipulate the spatial perception of audio content being listened to through the earbuds 1518a, 1518b. It will be understood that any number of other swipe and / or gesture inputs by the user at the user interface area of ​​the earbud charging case may manipulate the audio spatial perception of the audio output at the earbuds 1518a, 1518b. For example, a swipe from right to left may move the perceived position of the audio output from right to left or from front to back on the spatial audio band 1540. Transitions from one audio content source to another (e.g., when a user switches from audio content being sent by one or more other devices as described above) may be as described above. FIG. 15A to FIG. 15C 1518a, 1518b. In this way, a gesture applied in a certain direction along the capacitive touch surface of the device described herein can correspond to the perceived source location of the audio content output by the earbuds 1518a, 1518b. In this way, in at least one example, the device of the present disclosure can detect signals via user input gestures or other devices and transmit instructions corresponding to the input gestures or other signals and commands to one or more earbuds to change the perceived location or source of the audio content.

[0102] For example, if a user is listening to music through the earbuds and receives a notification from an output feature of the control box, such as a text message notification, the user can swipe or gesture at the user interface area of ​​the charging box to indicate that they want to hear the audio output of the text message. Fig.15A, the music being listened to may be spatially perceived from the position of sound 1544 on the spatial audio band 1540. When one or more processors of the charging case cause text message audio content to be sent to the earbuds 1518a, 1518b, for example, from a mobile phone source, the processor of the charging case may cause an audible reading of the text message to be sent to one or more of the earbuds 1518a, 1518b, such that the text message audio content is spatially perceived by the user as coming from the right, for example, sound 1546 on the spatial audio band 1540. Additionally, the text message audio content may gradually fade in and / or the music being listened to may fade out or be reduced in volume so that the text message audio content may be audible. Additionally, as the text message audio content of sound 1546 fades in, the music being listened to at sound 1544 may move to the left, for example, as Fig. 15C as shown in .

[0103] In at least one example, using a device and charging case with a processor and antenna as described herein, multiple audio content from multiple electronic devices with audio outputs can be simultaneously sent to earbuds 1518a, 1518b for the user to hear. In this example, one audio source can be spatially perceived at sound 1542, another audio source can be perceived at sound 1544, and another audio content can be perceived at sound 1546. In this way, as Fig. 15B and Fig. 15C As shown, multiple sources and audio content may be perceived simultaneously as if they were coming from different directions along the spatial band 1540. In other examples, any number of audio sources and sounds may be sent simultaneously to the earbuds 1518a, 1518b, with the sound output of each audio source being perceived at any number of spatial locations indicated by the spatial audio band 1540.

[0104] As described above, the spatial audio band 5140 represents a set of continuous locations where various sounds 1542, 1544, 1545, and 1546 can be perceived. However, by changing the volume and other characteristics of the sounds output through the earplugs 1518a, 1518b, the spatial audio band 1540 can be changed from more than FIG. 15A to FIG. 15C In addition, as also described above, the sound sources 1542, 1544, 1545, and 1546 output from the earplugs 1518a, 1518b can be perceived by the user 1505 as emanating from front to back, from left to right, from top to bottom, or in any combination. For example, Fig.15D As shown in FIG. 15A to FIG. 15CThe sounds 1542, 1544, 1545, and 1546 shown in the figure can be perceived as emanating along any number of three-dimensional spatial audio bands 1540a, 1540b, 1540c, and 1540d, or other bands not shown but located therebetween. In fact, user input commands (including gestures and touches at the user interface areas of the charging case and device described herein) can be used to move the perceived sound source from the earbuds 1518a, 1518b to anywhere around the user in any direction and at any distance, such as Fig.15D This is represented by the spatial audio bands 1540a, 1540b, 1540c and 1540d shown in FIG.

[0105] In this way, the charging case described herein can enable users to experience multiple audio sources and content as if they were in one room, for example, multiple people talking or multiple devices providing audio output from different directions. In some examples, the devices and systems described herein can simulate a real-world audio environment in which a user perceives different audio content from different locations and can focus on the content of his or her choice.

[0106] In at least one example, various sensors and spatial audio manipulation capabilities of a device described herein (e.g., an earbud charging case) may be utilized within an augmented reality (AR) or virtual reality (VR) environment. Fig.16A and Fig. 16B Such an example is shown in . AR / VR device 1604 (such as the head-mounted device shown) may include one or more sensors for identifying device 1600 (such as an earbud charging box). Once device 1600 is detected and located by AR / VR device 1604, a virtual representation of user interface area 1616 of device 1600 may be displayed to the user via display 1648 of AR / VR device 1604. In this example, the virtual representation of user interface area 1616 of device 1600 corresponds to an outer surface of device 1600 that is configured to receive touch input commands from the user. In at least one example, the same area of ​​the outer surface of device 1600 may not be visible when AR / VR device 1604 is not in use. In another example, the area of ​​the outer surface of device 1600 remains visible when AR / VR device 1604 is not in use.

[0107] Alternatively or additionally, the external area of ​​the device 1600 on which the virtual representation of the user interface 16 is presented to the user via the display 1648 of the AR / VR device 1604 is not actually configured to receive gesture commands from the user. In this example, the AR / VR device 1604 may include a processor, circuitry, and sensors configured to visually detect gestures performed by the user at the virtual representation of the user interface area 16 on the device 1600. The processor and other components of the AR / VR device 1604 (including one or more antennas) may then communicate the command and perform the associated function at the connected earbud 1618.

[0108] In one example, the gaze detection functionality of an AR / VR device 1604, which may include a head mounted device, may be used in conjunction with the spatial audio manipulation of the device described herein. For example, as the user's gaze switches from one thing to another in the AR / VR environment, the device described herein may spatially manipulate the audio output from the earbuds to match the user's gaze in the AR / VR environment. Advantageously, this may create a more immersive and realistic AR / VR experience for the user.

[0109] In addition to the various features, components, and advantages of the devices described herein, in at least one example, the device may include one or more microphones configured to receive user commands from a user. In such examples, one or more processors of the device may be configured to detect or recognize the user's voice through the one or more microphones. Voice or other audio commands may be used in conjunction with or independently of touch gesture input at the user interface area of ​​the charging case and device described herein.

[0110] In addition to or in lieu of the examples of devices and charging cases described herein, one or more devices may include one or more sensors, including health or biometric sensors. Such sensors may be incorporated into the housing of the devices described herein to track the user's biometric or health data. For example, when a user keeps the earbud charging case in his or her pocket, one or more sensors of the charging case may detect the number of steps taken by the user, the user's body temperature, or other health and biometric data. One or more processors of the charging case device may cause the charging case device to relay the sensed or detected biometric and health data to the user via one or more output features as described herein. Additionally or alternatively, the charging case device may be configured to send audio information containing health and biometric data sensed or detected by the sensor to the earbud.

[0111] One or more other sensors may be included in one or more other examples of the devices described herein. For example, one or more environmental sensing sensors may be included in a device such as an earbud charging case. Environmental sensors may include sensors configured to detect or sense other objects, electronic devices, or people within an environment, or other environmental characteristics. In one example, one or more sensors may sense the temperature, humidity, or other physical characteristics of the environment, and relay such information to the user via an earbud wirelessly connected to the charging case device or via one or more visual or tactile output features of the device. In examples where one or more sensors are configured to detect other objects or people within the environment, one or more processors of the charging case device may be configured to cause audio content related to those other objects, devices, or people to be sent to the user via the earbuds.

[0112] In addition or in lieu of the examples of devices and charging cases described herein, one or more devices may include one or more memory components as described above, such that the device is configured as a standalone radio or music playlist device. In addition, one or more examples of devices described herein may include one or more wireless Internet connection components or modules configured to connect the device to the Internet for streaming audio content.

[0113] In at least one example of a device described herein (such as an earbud charging case device described herein), multiple people can receive a transmission of audio content from the same device (e.g., a television or mobile phone), where each user charging case adapts the audio content to the needs of the user. This can be done automatically or at least by commands from the user via a user interface area of ​​the charging case. For example, if two or more people are watching and listening to television through their respective earbuds, each user can uniquely adapt the audio output to their needs. For example, some users may need or want the volume to be louder or quieter. For another example, some users may prefer to turn up the bass or treble components of the audio output. Advantageously, each user using the device described herein can change the audio output to meet their own needs without affecting the audio output sent to others. This can have unique and advantageous accessibility implications, providing a changed or enhanced audio experience to the hearing-impaired or other hearing-impaired people.

Such personal information may be used to practice and improve the various examples described herein. However, the disclosed technology cannot operate without such personal information data.

[0115] It should be understood that the various details of the present invention system and method provided above can be combined in various combinations and with alternative components. For the purpose of illustration and description, the foregoing description of the specific examples described herein is presented. They are not intended to be exhaustive or to limit the embodiments to the precise form disclosed. Instead, many modifications and variations are possible based on the above teachings.
