DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] Description will now be made in detail of representative embodiments as illustrated in the accompanying drawings. It should be understood that the following description is not intended to limit these embodiments to one preferred embodiment. On the contrary, the following description is intended to cover alternatives, modifications, and equivalents as may be included within the spirit and scope of the described embodiments as defined by the appended claims.

[0018] The following disclosure relates to a modular sensing assembly for use as part of an electronic device. The modular sensing assembly can receive a number of different types of user input. Exemplary user inputs include touch input, fingerprint input, translational input, voice input, biometric input, and the like. Input received using the modular sensing assembly can be used to control the graphical output of a display of the electronic device. The modular sensing assembly can be configured, for example, as a power button, a keyboard key, a control button (e.g., volume control), a home button, a watch crown, and the like.

[0019] The combination of multiple components in a modular sensing assembly provides advantages over conventional input mechanisms. Advantages include reduced redundancy of device components and manufacturing complexity. For example, the modular sensing assembly may include a single sealing member that provides sealing around all components of the modular sensing assembly and / or between the modular sensing assembly and the device housing. This can reduce the total number of parts required to assemble an electronic device, reducing manufacturing complexity and cost, and minimizing the size of the device. As another example, multiple components of the modular sensing assembly may be operably coupled to a processing unit using one or more common connectors and / or common passages to the internal volume of the device.

[0020] The modular sensing assembly may be disposed at least partially within a housing of the electronic device. Exemplary inputs received by the modular sensing assembly may include touch input, translational input, fingerprint input, audio input, electrocardiogram signals, etc. The modular sensing assembly may provide one or more outputs. Exemplary outputs provided by the modular sensing assembly include audio output, tactile output, visual output, etc.

[0021] As discussed in more detail below, a modular sensing assembly may include multiple sensors, subassemblies, and / or other components disposed within an assembly enclosure. Combining multiple components in a modular sensing assembly provides advantages over conventional input mechanisms. Advantages include device component redundancy and reduced manufacturing complexity. For example, a modular sensing assembly may include a single sealing member that provides a seal around all components of the modular sensing assembly and / or between the modular sensing assembly and the device housing. As another example, multiple components of a modular sensing assembly may be operably coupled to a processing unit using one or more common connectors and / or a common passageway to an internal volume of an electronic device.

[0022] The modular sensing assemblies described herein may include a sealing member that prevents contaminants from entering the interior volume and / or housing of the electronic device. As used herein, "contaminant" may be used to refer to a foreign object that is not intended to be present within the interior volume or electronic device. Examples of contaminants include liquids, such as water, and solid objects, such as lint, dust, and food particles. In one embodiment, a sealing member is disposed between one or more components of the modular sensing assembly and one or more surfaces of the housing of the electronic device.

[0023] As used herein, the term "attached" may be used to refer to two or more elements, structures, objects, components, parts, etc. that are physically affixed, fastened, and / or held together. As used herein, the term "coupled" may be used to refer to two or more elements, structures, objects, components, parts, etc. that are physically attached to one another, operate with one another, communicate with one another, electrically connect with one another, and / or otherwise interact with one another. Thus, elements that are attached to one another are coupled to one another, but not necessarily vice versa. As used herein, "operably coupled" or "electrically coupled" may be used to refer to two or more devices that are coupled in any suitable manner for operation and / or communication, including wired, wireless, or some combination thereof.

[0024] These and other embodiments are discussed with reference to Figures 1A-4. However, those skilled in the art will readily appreciate that the detailed description provided herein with reference to these figures is for purposes of illustration only and should not be construed as limiting.

[0025] 1A illustrates a block diagram of an exemplary electronic device 100 that may incorporate a modular sensing assembly 110. The electronic device 100 may include a display 122, one or more input devices 124, one or more output devices 126, and the modular sensing assembly 110. Each of the components of the electronic device 100 may be operatively coupled to a processing unit 128. The electronic device 100 may include a housing 120. The components of the electronic device 100 may be at least partially disposed within an interior volume 121 of the housing 120.

[0026] Modular sensing assembly 110 may be at least partially disposed within housing 120 of electronic device 100 and may be configured to receive input and / or provide output. Exemplary inputs received by modular sensing assembly 110 may include touch input, translational input, fingerprint input, audio input, electrocardiogram signals, etc. Exemplary outputs provided by modular sensing assembly 110 may include audio output, tactile output, visual output, etc. Modular sensing assembly 110 may be operably coupled to processing unit 128, for example by connector 130a.

[0027] As discussed in more detail below, the modular sensing assembly 110 may include multiple sensors, subassemblies, and / or other components disposed within an assembly enclosure. The combination of multiple components in the modular sensing assembly 110 provides advantages over conventional input mechanisms. Advantages include device component redundancy and reduced manufacturing complexity. For example, the modular sensing assembly 110 may include a single sealing member that provides a seal around all components of the modular sensing assembly 110 and / or between the modular sensing assembly 110 and the housing 120. As another example, multiple components of the modular sensing assembly 110 may be operably coupled to a processing unit using one or more common connectors and / or a common passageway to the interior volume 121.

[0028] In various embodiments, display 122 may be at least partially disposed within interior volume 121 of housing 120. Display 122 provides graphical output associated with, for example, an operating system, a user interface, and / or applications of electronic device 100. In one embodiment, display 122 includes one or more sensors and is configured as a touch-sensitive (e.g., single-touch, multi-touch) and / or force-sensitive display for receiving input from a user. Display 122 is operably coupled to processing unit 128 of electronic device 100, for example, by connector 130b. In some cases, the graphical output of display 122 is viewable along at least a portion of an exterior surface of electronic device 100.

[0029] In various embodiments, the graphical output of the display 122 is responsive to inputs provided by the display, the one or more input devices 124, and / or the one or more modular sensing assemblies 110. For example, the processing unit 128 may be configured to modify the graphical output of the display 122 in response to determining an electrocardiogram, receiving a rotational input, receiving a translational input, receiving a touch input, receiving a fingerprint input, receiving a voice input, etc. In some cases, the haptic output provided by the modular sensing assembly 110 corresponds to the graphical output of the display 122. In some cases, the modular sensing assembly 110 may generate a haptic output that is coordinated with a change in the graphical output of the display 122. For example, the haptic output may be generated simultaneously or approximately simultaneously with a change in the graphical output of the display 122. In some cases, the time at which the haptic output is generated overlaps with the time at which the graphical output of the display 122 changes.

[0030] Display 122 may be implemented using any suitable technology, including but not limited to liquid crystal display (LCD) technology, light emitting diode (LED) technology, organic light-emitting display (OLED) technology, organic electroluminescence (OEL) technology, or another type of display technology. In some cases, display 122 is disposed beneath a cover and is viewable through the cover.

[0031] In general, the input devices 124 can detect various types of inputs, and the output devices 126 can provide various types of outputs. The modular sensing assembly 110 can be an example of the input device 124. Similarly, the modular sensing assembly 110 can be an example of the output device 126. The processing unit 128 can be operatively coupled to the input devices 124 and the output devices 126, for example, by connectors 130c and 130d, respectively. The processing unit 128 can receive input signals from the input devices 124 in response to inputs detected by the input devices. The processing unit 128 can interpret the input signals received from one or more of the input devices 124 and send output signals to one or more of the output devices 126. The output signals can cause the output devices 126 to provide one or more outputs. The inputs detected by one or more of the input devices 124 can be used to control one or more functions of the electronic device 100.

[0032] In some cases, one or more of the output devices 126 may be configured to provide output that is dependent on or manipulated in response to input detected by one or more of the input devices 124. Output provided by one or more of the output devices 126 may also be responsive to or initiated by programs or applications executed by the processing unit 128 and / or associated companion devices. Examples of suitable processing units, input devices, output devices, and displays are described in more detail below with respect to FIG.

[0033] 1B illustrates a block diagram of the example modular sensing assembly 110 of FIG. 1A. Modular sensing assembly 110 may include a touch sensor 140, a fingerprint sensor 142, a translation sensor 144, an audio sensor 146, electrocardiograph (ECG) electrodes 148, and one or more output devices 149. As described above, the components of modular sensing assembly 110 may be at least partially disposed within assembly enclosure 111.

[0034] Touch sensor 140 may be any suitable device for detecting touch input to modular sensing assembly 110. As used herein, "touch input" may refer to any contact or near-contact by a user (e.g., a user's finger) or another object with one or more input surfaces of modular sensing assembly 110. Touch input may be a tap, a press, a gesture (e.g., a swipe), etc.

[0035] Touch sensor 140 may be implemented with a capacitive sensor, a resistive sensor, a contact sensor, a magnetic sensor, an optical sensor, an ultrasonic sensor, etc. Touch sensor 140 can provide a signal in response to a touch input that can indicate that a touch input occurred, the type of input (e.g., a tap, a press, a gesture, etc.), where the input occurred, and / or a measurement of the input (e.g., a force measurement). In some cases, modular sensing assembly 110 includes a cover defining an input surface on an exterior surface of the modular sensing assembly, and touch sensor 140 can be disposed under the cover of modular sensing assembly 110 to detect touch input on or near the input surface.

[0036] Output provided by electronic device 100 may be responsive to touch input detected using touch sensor 140. For example, graphical output provided by display 122 and / or audio output provided by an audio output device may be responsive to touch input detected using touch sensor 140.

[0037] Fingerprint sensor 142 may be any suitable device for detecting a fingerprint input in modular sensing assembly 110. As used herein, a “fingerprint input” may refer to any representation of a user's fingerprint, including a fingerprint image, a fingerprint map, etc. The fingerprint input may be used by processing unit 128 to perform authentication operations in electronic device 100.

[0038] The fingerprint sensor 142 may be implemented with a capacitive sensor, a resistive sensor, a contact sensor, a magnetic sensor, a light sensor, an ultrasonic sensor, a camera, and the like. The fingerprint sensor 142 may provide a signal in response to a fingerprint input that may include information related to the fingerprint input. In some cases, the fingerprint sensor 142 may be disposed under a cover of the modular sensing assembly 110 to detect a fingerprint input on or near the input surface. The fingerprint sensor 142 may be an area sensor, meaning that the fingerprint sensor 142 does not require a swipe of the user's finger to capture enough of the fingerprint to uniquely identify the user. The fingerprint sensor 142 may have a sufficiently high resolution such that it may be used to uniquely identify an individual using a relatively small portion of the user's fingerprint. In some cases, the input surface has a width of 2 mm to 5 mm, and the fingerprint sensor 142 may still uniquely identify an individual using a fingerprint captured on the input surface. In some cases, the fingerprint sensor 142 may be a swipe fingerprint sensor.

[0039] Output provided by electronic device 100 may be responsive to fingerprint input detected using fingerprint sensor 142. For example, graphical output provided by display 122 and / or audio output provided by an audio output device may be responsive to fingerprint input detected using fingerprint sensor 142.

[0040] The translation sensor 144 may be any suitable device for detecting a translational input in the modular sensing assembly 110. As used herein, a "translational input" may refer to an input to the modular sensing assembly 110 that causes the modular sensing assembly, or a portion thereof, to move or translate. Translation may include inward and outward translation, lateral translation, and other movements of one or more components (e.g., a cover) of the modular sensing assembly 110. For example, the cover of the modular sensing assembly 110 may be depressed in response to a user pressing on the input surface. The modular sensing assembly 110, or a portion thereof, may translate inward in response to a user pressing on the input surface. The translation sensor 144 may detect this as a translational input.

[0041] The translational sensor 144 may be implemented with a physical switch (e.g., a tactile dome switch), a capacitive sensor, a resistive sensor, a contact sensor, a magnetic sensor, an optical sensor, an ultrasonic sensor, etc. The translational sensor 144 can provide a signal in response to a translational input that can indicate that a translational input has occurred, where the input has occurred, and / or a measurement of the input (e.g., a force measurement). In some cases, the translational sensor 144 is disposed under a cover of the modular sensing assembly 110 and can detect a translational input on or near an input surface.

[0042] Output provided by electronic device 100 may be responsive to translational input detected using translation sensor 144. For example, graphical output provided by display 122 and / or audio output provided by audio output device may be responsive to translational input detected using translation sensor 144.

[0043] The audio sensor 146 may be any suitable device for detecting audio input in the modular sensing assembly 110. As used herein, "audio input" may refer to any detected or measured sound. For example, the audio sensor 146 may detect sounds from the environment surrounding the electronic device 100 for voice commands and other device control, recording, noise level detection, voice communication (e.g., a phone call), etc.

[0044] The audio sensor 146 may be implemented as a microphone or any device for measuring or detecting an audio signal. The audio sensor 146 may provide a signal corresponding to the audio input to the processing unit 128. In some cases, the audio sensor 146 may be disposed under a cover of the modular sensing assembly 110 to detect the audio input through the cover and / or through an opening in the cover.

[0045] Output provided by electronic device 100 may be responsive to audio input detected using audio sensor 146. For example, graphical output provided by display 122 and / or audio output provided by an audio output device may be responsive to audio input detected using audio sensor 146.

[0046] ECG electrodes 148 may be disposed on one or more exterior surfaces of modular sensing assembly 110. A processing unit 128 or other sensing circuitry of electronic device 100 may monitor voltages or signals received at ECG electrodes 148. Electronic device 100 may include one or more additional electrodes disposed on an exterior surface of the electronic device that may be used to provide electrocardiogram functionality to the electronic device.

[0047] In some embodiments, the ECG electrodes 148 may be disposed (e.g., PVD deposited) on an outer surface of the modular sensing assembly 110. The ECG electrodes 148 may be disposed on an outer surface of a cover of the modular sensing assembly 110. The surface may be any transparent, translucent, translucent or opaque surface made from an amorphous solid, glass, a crystal or crystalline material (such as sapphire or zirconia), plastic, or the like. The ECG electrodes 148 may be disposed along a portion of the periphery of the cover of the modular sensing assembly (e.g., the cover forming the input surface). A portion of the periphery of the cover may be curved and the ECG electrodes 148 may conform to the curvature of the periphery of the cover. As an example, the portion of the periphery of the cover on which the ECG electrodes 148 are disposed may define a 180° curve. The ECG electrodes 148 may at least partially surround an area of ​​the cover that does not include ECG electrodes. The ECG electrodes 148 may have a C-shape or a U-shape and may at least partially surround a portion of the cover where no ECG electrodes are present. The ECG electrodes 148 may extend from an outer surface of the cover, around the edge of the cover, and to a connector underneath the cover (e.g., a connector coupled to the inner surface of the cover). This may improve the modular sensing assembly 110's ability to exclude contaminants by eliminating the need to thread a connector through a hole in the cover or another component of the electronic device 100.

[0048] Output provided by electronic device 100 may be responsive to signals received at the ECG electrodes 148. For example, graphical output provided by display 122 and / or audio output provided by an audio output device may be responsive to signals received at the ECG electrodes 148.

[0049] Output device(s) 149 can provide output in modular sensing assembly 110. Output device 149 may include a haptic output device (e.g., a haptic actuator) for providing haptic output, an audio output device (e.g., a speaker) for providing audio output, and / or a visual output device (e.g., a light) for providing visual output.

[0050] As used herein, the terms "haptic output" and "tactile output" can refer to an output generated by an electronic device that can be perceived through user touch. Examples of haptic output include vibrations, deflections, and other movements of a device housing, device cover, or input device, or another device component that forms an input surface of the electronic device. In some cases, the haptic output may provide feedback regarding an input received at a particular location of the electronic device. For example, a haptic output can be provided at the modular sensing assembly 110 to provide feedback related to an input provided at the modular sensing assembly. In other cases, the haptic output can provide other types of feedback or information to a user, such as an alert received at the electronic device.

[0051] Modular sensing assembly 110 may include more or fewer components than those shown and described with respect to FIG. 1B. In some cases, a single device or subassembly may provide the functionality described with respect to multiple components above. For example, a single audio device may be capable of detecting voice input and providing voice input. As another example, a single sensing device may be capable of detecting touch input and fingerprint input. Similarly, a single sensing device may be capable of detecting touch input and translation input.

[0052] 2A-2C illustrate an exemplary electronic watch 200 that includes a modular sensing assembly 210. The electronic watch 200 can have the same or similar functionality and structure as the electronic device 100 discussed with respect to Figures 1A and 1B. Other devices that can incorporate the modular sensing assemblies described herein include other wearable electronic devices, other timekeeping devices, other health monitoring or fitness devices, other portable computing devices, mobile phones (including smartphones), tablet computing devices, digital media players, virtual reality devices, audio devices (including earbuds and headphones), and the like.

[0053] 2A, electronic watch 200 can include a watch body 220 and a watch band 224. Watch body 220 can include a housing 222. Housing 222 can include one or more components of electronic watch 200 and can define at least a portion of an exterior surface of the electronic watch.

[0054] The modular sensing assembly 210 can be disposed in a recess 228 along the sidewall 222a of the housing 222. The modular sensing assembly 210 can include a cover 212 that defines at least a portion of an input surface 214 that forms a part of the exterior surface of the electronic watch 200. The input surface 214 can include multiple areas for detecting different types of input. For example, as shown in FIG. 2A, the input surface 214 can include an ECG area 214a where an ECG signal can be detected, a fingerprint sensing area 214b where a fingerprint input can be detected, and an audio sensing area 214c including an opening 216 where an audio signal can be detected. In some cases, the ECG area 214a, the fingerprint sensing area 214b, and / or the audio sensing area 214c can be touch sensitive areas that can receive touch input.

[0055] The modular sensing assembly 210 may be capable of receiving a translational input. For example, a user may press the input surface 214 inward to provide a translational input to the modular sensing assembly 210. The cover 212 may translate inward in response to the translational input. In some cases, the cover 212 may deflect or flex in response to the translational input. In some cases, the cover 212 may not translate, deflect, or flex in response to the translational input. The modular sensing assembly 210 may include one or more translational sensors to detect the translational input.

[0056] The ECG area 214a may include ECG electrodes 218 disposed on an outer surface of the cover 212. The ECG electrodes 218 may be configured to detect ECG signals, for example, from a user's finger placed on the ECG electrodes. The ECG signals may be used to provide an electrocardiogram function to the electronic watch 200. As shown in FIG. 2A, the ECG electrodes 218 may be disposed along a portion of the circumference of the cover 212. The portion of the circumference of the cover 212 may be curved, and the ECG electrodes 218 may conform to the curvature of the circumference of the cover 212. As an example, the portion of the circumference of the cover 212 on which the ECG electrodes 218 are placed may define a 180° curve, as shown in FIG. 2A. The ECG electrodes 218 may at least partially surround an area of ​​the outer cover that does not include ECG electrodes. For example, as shown in FIG. 2A, the ECG electrodes 218 have a C-shape or a U-shape and at least partially surround a portion of the ECG area 214a where no ECG electrodes are present. As discussed in more detail below, the ECG electrodes 218 may extend from the exterior surface of the cover 212, around the edge of the cover, to a connector underneath the cover (e.g., a connector coupled to the interior surface of the cover). This may improve the ability of the modular sensing assembly 210 to exclude contaminants by eliminating the need to thread a connector through holes in the cover 212 or another component of the electronic watch 200.

[0057] The ECG electrodes 218 may be formed from any suitable material or combination of materials for receiving ECG signals, including metals and other conductive materials. The cover 212, or one or more portions thereof, may be formed from a non-conductive material to electrically insulate the ECG electrodes 218 from other components of the electronic watch 200 to reduce interference and signal noise introduced to the ECG signal. In some cases, the modular sensing assembly 210 may include an insulating component disposed between the ECG electrodes 218 and one or more additional components of the modular sensing assembly to reduce interference and signal noise introduced to the ECG signal.

[0058] The cover 212 may be configured to allow an input to be detected by a component of the modular sensing assembly 210 disposed beneath the cover. The cover 212 may be formed from or include a non-conductive and / or dielectric material that allows a sensing signal, such as a capacitive signal, an ultrasonic signal, to pass through the cover. By way of example, the cover 212 may be formed from sapphire. The cover 212 may be formed from a transparent or translucent material to allow an optical sensing signal to pass through the cover. In some cases, structural features of the cover 212 allow signals to pass through the cover. For example, the cover may include an opening that allows a sensing signal (e.g., an optical signal) to pass through the cover.

[0059] In some cases, the electronic watch 200 may include a display cover 226 that faces away from the user's skin when the watch 200 is worn. In some cases, the display cover 226 is mounted to or coupled to the housing 222. The display cover 226 may be disposed over and protect a display (e.g., display 122 of FIG. 1A) mounted within the housing 222. The display may be viewable by a user through the display cover 226. In some cases, the display cover 226 may be part of a display stack, which may include touch-sensing or force-sensing capabilities. The display may be configured to depict a graphical output of the electronic watch 200, and the user may interact with the graphical output (e.g., using a finger, stylus, or other pointer). As an example, the user may select (or otherwise interact with) a graphic, icon, etc. presented on the display by touching or pressing the display (e.g., providing touch input) at the location of the graphic. In some cases, the haptic output provided by the haptic device corresponds to the graphical output of the display and / or input received via the display.

[0060] As used herein, the term "display cover" may be used to refer to any transparent, translucent, or light-transmitting surface made from glass, crystalline materials (such as sapphire or zirconia), plastic, or the like. Thus, as used herein, the term "display cover" should be understood to encompass amorphous solids as well as crystalline solids. In some embodiments, the display cover 226 may be a sapphire cover. The display cover 226 may also be formed of glass, plastic, or other materials.

[0061] The watch band 224 can be used to secure the electronic watch 200 to a user, another device, a retention mechanism, or the like. The housing 222 can include structure for attaching the watch band 224 to the watch body 220. In some cases, the structure can include an elongated recess or opening into which an end of the watch band 224 can be inserted and attached to the watch body 220. In other cases (not shown), the structure can include a recess (e.g., a depression or recess) in the housing 222 that can receive an end of a spring pin attached to or threaded through an end of the watch band to attach the watch band to the watch body.

[0062] 2B is a partial exploded view of an example electronic watch 200. FIG. 2B illustrates example components of modular sensing assembly 210 and an exterior cutaway portion of housing 222. Modular sensing assembly 210 may include cover subassembly 250, trim member 260, sensing subassembly 270, button subassembly 280, translation sensors 292a, 292b, and retaining bracket 294. The components of modular sensing assembly 210 may be coupled together and / or to housing 222 using one or more fasteners (e.g., fasteners 296a, 296b).

[0063] The modular sensing assembly 210 can be disposed within a recess along a sidewall 222a of the housing 222, as described in more detail below with respect to FIG. 2C. The sidewall 222a can define one or more passages 290a, 290b that extend through the sidewall into the interior volume of the electronic watch 200. The passages 290a, 290b can facilitate attachment of the modular sensing assembly 210 to the housing 222, as described in more detail below with respect to FIG. 2C. Additionally, the passages 290a, 290b can facilitate transmission of signals from the modular sensing assembly to the interior volume of the electronic watch 200 (e.g., using a connector that operably couples components of the modular sensing assembly 210 to a processing unit or other circuitry of the electronic watch 200).

[0064] As shown in FIG. 2B , the cover 212 of the modular sensing assembly 210 may be part of a cover subassembly that includes the membrane 256, the ECG electrodes 218, and the ECG connector 258. The ECG electrodes 218 may extend from an outer surface of the cover 212, around the edge of the cover, to the connector 258 underneath the cover. The connector 258 may be coupled to an inner surface of the cover 212 and may extend through passages 290a, 290b into the interior volume of the electronic watch 200 (e.g., to a processing unit or other circuitry of the electronic watch 200). This may provide a clear signal path for the ECG signals from the ECG electrodes 218 to the processing unit while electrically isolating the signals from the housing and the touch sensor. The ECG electrodes 218 and associated circuitry may be shielded from, operate at a different frequency than, or be configured to reduce parasitic effects with, the touch sensor 272 and / or other components of the modular sensing assembly 210.

[0065] The sensing subassembly 270 may be disposed under the cover 212 and may include a touch sensor 272 and an audio sensor 274. The touch sensor 272 may detect touch input on the input surface 214 of the cover 212. As discussed above with respect to FIG. 1B, the touch sensor 272 may be implemented as a capacitive sensor, a resistive sensor, a contact sensor, a magnetic sensor, a light sensor, an ultrasonic sensor, or the like. In some cases, the touch sensor 272 is also a fingerprint sensor that detects fingerprint input on the input surface 214. For example, the touch sensor 272 may be a capacitive sensor configured to detect touch input and fingerprint input on the input surface. The fingerprint sensor may be implemented as a capacitive sensor, a resistive sensor, a contact sensor, a magnetic sensor, a light sensor, an ultrasonic sensor, a camera, or the like. In some cases, the modular sensing assembly 210 may include a touch sensor and a fingerprint sensor that are separate components.

[0066] The sound sensor 274 may be disposed below the opening 216 in the cover 212 and may be configured to detect sound input. The membrane 256 may be disposed below the opening 216 in the cover 212 to prevent ingress of contaminants into the interior volume of the modular button assembly and / or electronic watch 200 via the opening 216. The membrane may be at least partially transparent to sound waves to allow the sound sensor 274 to detect sound input. The membrane 256 may be formed from any suitable material that is at least partially transparent to sound waves and forms a barrier to exclude contaminants.

[0067] The sensing subassembly 270 may also include one or more connectors 276 that operably couple the touch sensor 272 and the audio sensor 274 to a processing unit or other circuitry of the electronic watch 200. The connectors 276 may extend into the interior volume of the electronic watch 200 through passages 290a, 290b.

[0068] The trim member 260 may extend at least partially around the cover 212 and may at least partially enclose the cover 212, the touch sensor 272, and the audio sensor 274. As discussed in more detail below, the trim member 260 may form part of an assembly enclosure of the modular sensing assembly.

[0069] The button subassembly 280 may include a sealing member 282, a button retainer 284, and a button member 288. The button member 288 may be disposed within an opening formed by the sealing member 282 and / or the button retainer 284. The button retainer 284 may at least partially surround the button member 288, and the sealing member 282 may extend around the button retainer 284. As described in more detail below with respect to FIG. 2C, the button member 288 may communicate a force applied to the cover 212 to translation sensors 292a, 292b to recognize a translational input.

[0070] The sealing member 282 may be a compressible gasket that forms a seal between the housing 222 and the modular sensing assembly 210. For example, as shown in FIG. 2C, the sealing member 282 may be disposed along an inner surface of the recess 228. The sealing member 282 may extend into the interior volume around one or more passages 290a, 290b to prevent contaminants from entering the interior volume via the passages. The sealing member 282 may have a shape that causes it to compress or otherwise deform in response to translation of the cover 212, the trim member 260, or other components of the modular sensing assembly 210. In some cases, the sealing member 282 is co-molded with the button retainer 284 to simplify the assembly process of the modular sensing assembly 210.

[0071] The translational sensors 292a, 292b may be configured as any suitable device for detecting a translational input in the modular sensing assembly 210. Each translational sensor 292a, 292b may be implemented as a physical switch (e.g., a tactile dome switch), a capacitive sensor, a resistive sensor, a contact sensor, a magnetic sensor, an optical sensor, an ultrasonic sensor, etc. The translational sensors 292a, 292b may provide a signal in response to a translational input that may indicate that the translational input has occurred, where the input has occurred, and / or a measurement of the input (e.g., a force measurement).

[0072] The retaining bracket 294 may be disposed along an inner surface of the sidewall 222a. The retaining bracket 294, along with fasteners 296a, 296b, may be used to couple the components of the modular sensing assembly 210 together. The button retainer 284 may include a coupling mechanism that allows the fasteners to couple the button subassembly 280 to the retaining bracket 294. For example, the button retainer 284 may include female threaded connectors 286a, 286b configured to interconnect with threads of the fasteners 296a, 296b.

[0073] The retaining bracket 294 and fasteners 296a, 296b may be used to secure the modular sensing assembly 210 to the housing 222. The retaining bracket 294 may be coupled to the button retainer 284 to secure the modular sensing assembly 210 to the housing 222.

[0074] In some cases, the modular sensing assembly 210 may include an assembly enclosure formed by one or more components. The assembly enclosure may at least partially surround and / or encapsulate various components of the modular sensing assembly 210, allowing the modular sensing assembly 210 to reduce the number of sealing materials required. For example, the components of the sensing subassembly may be at least partially enclosed by the assembly enclosure. The assembly enclosure may be formed by one or more of the cover 212, the trim member 260, the sealing member 282, the button retainer 284, and the retainer bracket 294.

[0075] 2C illustrates a cross-sectional view of the example electronic watch 200 of FIG. 2A along section line AA. As described above, the modular sensing assembly 210 can be disposed within a recess 228 along the side wall 222a of the housing 222.

[0076] The modular sensing assembly 210 can receive a translational input that causes the cover 212 to translate or otherwise move. With reference to FIG. 2C , a translational input applied to the input surface 214 can cause the cover 212 to translate downward toward the translational sensors 292a, 292b. The button member 288 can be disposed between the cover 212 and the translational sensors 292a, 292b and configured to translate in response to a translational input on the input surface that causes the cover 212 to translate. The button member 288 can transmit a force applied to the cover 212 to the translational sensors 292a, 292b to recognize the translational input.

[0077] Translation of the button member 288 can activate one or both of the translation sensors 292a, 292b. In some cases, the button member 288 can move in a rocking motion to depress one of the translation sensors 292a, 292b based on the position of the translation input. For example, a translation input to a first region of the cover 212 (e.g., the left side of the cover with respect to FIG. 2C) can depress a first end (e.g., the left end) of the button member, thereby activating the translation sensor 292a. Similarly, a translation input to a second region of the cover 212 (e.g., the right side of the cover with respect to FIG. 2C) can depress a second end (e.g., the right end) of the button member, thereby activating the translation sensor 292b. The button member 288 can be positioned along the portion 222b of the housing of the electronic watch 200 or another component to facilitate rocking motion of the button member.

[0078] The passages 290a, 290b can facilitate mounting of the modular sensing assembly 210 to the housing 222. For example, a retaining bracket 294 can be disposed along the inner surface of the side wall 222a, and fasteners 296a, 296b can pass through the passages 290a, 290b to couple other components of the modular sensing assembly 210 to the retaining bracket 294. Coupling the components of the modular sensing assembly 210 to the retaining bracket 294 can secure the modular sensing assembly 210 to the housing 222.

The button member may be aligned with a passage 390c in the sidewall 322a that is aligned with a translational sensor 392. When the button member 388 translates in response to the translational input, the translational sensor 392 may be activated. In some cases, a component of the modular sensing assembly 310 does not move in response to the translational input, and the translational sensor 392 detects a force applied to the cover 312.

[0084] 3C illustrates a cross-sectional view of the example electronic watch 300 of FIG. 3A along section line BB. As described above, the modular sensing assembly 310 can be disposed within a recess 328a along the sidewall 322a of the housing 322.

[0087] The crown body 318a may be user rotatable and may be manipulated (e.g., rotated, pressed) by the user to rotate or translate the shaft 318b. The shaft 318b may be mechanically, electrically, magnetically, and / or optically coupled to components within the housing 322. User manipulation of the crown body 318a and shaft 318b may be used to manipulate or select various elements displayed on the display, adjust the speaker volume, turn the watch 300 on or off, etc. The crown body 318a may be electrically coupled to the circuitry (e.g., processing unit) within the housing 322, but is electrically isolated from the housing 322. The crown 318 may include conductive electrodes used to measure ECG or other health-related measurements.

[0088] The retaining bracket 394 may be disposed along an inner surface of the side wall 322a.

In one embodiment, the display 412 includes one or more sensors and is configured as a touch-sensitive (e.g., single-touch, multi-touch) and / or force-sensitive display for receiving input from a user. For example, the display 412 can be integrated with touch sensors (e.g., capacitive touch sensors) and / or force sensors to provide a touch-sensitive and / or force-sensitive display. The display 412 is operably coupled to the processing unit 402 of the electronic device 400.

[0099] As mentioned above, in some cases, the input device(s) 406 include a touch sensor (e.g., a capacitive touch sensor) integrated with the display 412 to provide a touch-sensitive display. Similarly, in some cases, the input device(s) 406 include a force sensor (e.g., a capacitive force sensor) integrated with the display 412 to provide a force-sensitive display.

[0101] In some cases, the input device(s) 406 and the output device(s) 410 are implemented together as a single device. For example, the input / output devices or ports can transmit electronic signals over a communication network, such as wireless and / or wired network connections. Examples of wireless and wired network connections include, but are not limited to, cellular connections, Wi-Fi connections, Bluetooth connections, IR connections, and Ethernet connections.
