Description

Technical Field

[0001] The present invention relates to a wearable device, and in particular to an in-ear wearable device and a panel assembly thereof. Background Art

[0002] With the development of science and technology, smart wearable devices such as smart watches, smart bracelets, smart glasses, virtual reality / augmented reality (VR / AR) devices have gradually become popular and become an important part of people's lives. In-ear wearable devices have become one of the important types of smart wearable devices due to their advantages such as easy wearing and no interference with the activities of both hands.

[0003] However, most of the current in-ear wearable devices are standard-sized products. Due to the different shapes and sizes of the ear canals of each user, standard-sized products have problems such as users being uncomfortable to wear and the devices being easy to fall off, which limits the wearing time and application scenarios of the devices. Therefore, customized in-ear wearable devices have received more attention. Summary of the invention

[0004] For customized in-ear wearable devices, since the customized parts (such as the shell) have different shapes and sizes for different users, some components that need to interact with the outside of the device or need to be connected to the outside of the device are difficult to install on the customized parts. In this case, the present invention considers installing these components on the panel, such as under the panel, but how to arrange the components so that they occupy less panel space and internal space of the device while being able to work normally is one of the technical problems to be solved by the present invention.

[0005] The present invention reduces the space occupied by at least some components on the panel and in the housing by compactly arranging at least some components together, thereby reducing the size of the panel assembly and the device while allowing these components to work normally, thereby improving the adaptability of the panel assembly and the wearing comfort of the device.

[0006] In one embodiment, a panel assembly of an in-ear wearable device is provided, including a panel, a mainboard, a control device, a charging device, a battery, an antenna device, a sound pickup device, a speaker assembly, and a wireless communication module, wherein:

[0008] In a plane perpendicular to the panel or the control device, the orthographic projection of the control device and the orthographic projection of the charging device partially overlap;

[0009] In a plane where the panel or the operating device is located, the minimum circumscribed circle of the orthographic projection of the operating device and the minimum circumscribed circle of the orthographic projection of the charging device at least partially overlap.

[0010] In one embodiment, the overlap ratio R of the minimum circumscribed circle of the orthographic projection of the manipulation device and the minimum circumscribed circle of the orthographic projection of the charging device is:

[0011]

[0012] And the overlap ratio R is 70% to 100%,

[0013] wherein, S 1 represents the area of the minimum circumscribed circle of the orthographic projection of the manipulation device, S 2 represents the area of the minimum circumscribed circle of the orthographic projection of the charging device, S 0 represents the area of the overlapping part of the above two minimum circumscribed circles, and max(S 1 , S 2 ) represents the larger value of S 1 and S 2 .

[0014] In one embodiment, the charging device may include a plurality of charging pins, and the plurality of charging pins extend into the opening of the panel through the manipulation device.

[0015] In one embodiment, the manipulation device may include through holes and / or recesses for the plurality of charging pins to pass through.

[0016] In one embodiment, the manipulation device may include a first through hole at the center and a second through hole or recess at a non - central position.

[0017] In one embodiment, the plurality of charging pins include at least one first - polarity charging pin and at least one second - polarity charging pin. The first - polarity charging pin extends into the opening of the panel through the first through hole, and the second - polarity charging pin extends into the opening of the panel through the second through hole or recess.

[0018] In one embodiment, the number of the first - polarity charging pins is 1, the number of the second - polarity charging pins is 3, and the second - polarity charging pins are arranged in an equilateral triangle with the first - polarity charging pin as the center.

[0019] In one embodiment, the through hole is a circular hole, an oval hole or an arc - shaped hole.

[0020] In one embodiment, the minimum distance between the plurality of charging pins and the outer contour of the manipulation device is within 2 mm.

[0021] In one embodiment, the upper ends of the plurality of charging pins are flush with the upper surface of the panel, the upper ends of the plurality of charging pins are all lower than the upper surface of the panel, or the upper end of at least one charging pin among the plurality of charging pins is flush with the upper surface of the panel and the upper ends of the other charging pins are lower than the upper surface of the panel.

[0022] In one embodiment, multiple charging pins are arranged in an arc shape outside the control device.

[0023] In one embodiment, the control device is generally circular or oval.

[0024] In one embodiment, the diameter of the minimum circumscribed circle of the control device is 5 - 8 mm.

[0025] In one embodiment, the diameter of the minimum circumscribed circle of the control device is 5 - 6 mm.

[0026] In one embodiment, the panel assembly may further include a magnet, and the orthographic projections of the control device and the charging device on a cross-section of the magnet are located within the cross-section.

[0027] In one embodiment, when the user wears the in-ear wearable device, the projection of the panel in the direction of the user's ear is located within the ear contour.

[0029] In one embodiment, in the plane where the panel or the control device is located, the orthographic projection of the housing covers all or most of the orthographic projections of the panel, the control device, the charging device, the battery, the antenna device, and the sound pickup device.

[0030] In one embodiment, that the orthographic projection of the housing covers most of the orthographic projections of the panel, the control device, the charging device, the battery, the antenna device, and the sound pickup device means that, in the plane where the panel or the control device is located, more than 85% of the area defined by the outer contour of the orthographic projections of the panel, the control device, the charging device, the battery, the antenna device, and the sound pickup device is within the range of the orthographic projection of the housing.

[0031] In one embodiment, the housing is a customized housing formed based on the shape and size of the user's ear. The housing includes a first protruding portion and a second protruding portion.

Thus, the size of the panel assembly and the in-ear wearable device is reduced while enabling the control device and the charging device to operate properly, improving the adaptability rate of the panel assembly and the wearing comfort of the device.

[0044] The detailed embodiments of the present application will be described below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals are used to denote the same or similar components, and their repeated description is omitted for simplicity.

[0045] Figure 1FIG. 0 is a perspective view of a customized in-ear wearable device 10 according to an embodiment of the present invention. The customized in-ear wearable device 10 may be, for example, a customized wireless earphone. Only a single device (e.g., the device worn on the left ear) is shown in Figure 1 , but those skilled in the art understand that the customized in-ear wearable device 10 may include two devices worn on the left ear and the right ear respectively, and their structures may be substantially symmetric and communicate wirelessly. Here, only one of the devices is illustrated and described for simplicity. Referring to Figure 1 , the customized in-ear wearable device 10 according to this embodiment includes a panel assembly 100 and a customized housing 500. The housing 500 may be a customized housing formed based on the shape and size of the user's ear. For example, it may be manufactured by taking an ear mold of the user's ear (including parts such as the external auditory canal, concha, and / or cymba conchae), and then using manufacturing equipment based on the taken ear mold. The manufacturing method may be, for example, 3D printing. The size of the customized housing 500 may be the same as the taken ear mold, or slightly smaller than the taken ear mold to improve the wearing comfort of some sensitive users.

[0046] Most current in-ear wearable devices are standard-size products. Due to the different shapes and sizes of each user's ear canal, standard-size products have problems such as uncomfortable wearing for users and easy detachment of the device, thus limiting the wearing time and application scenarios of the device. In the case where the device is a standard-size product, in order to fit the ear sizes (such as the concha) of most users, its size needs to be as small as possible. However, in order to ensure stable wearing without falling off, some protrusions need to be provided to stably position the device on the ear. In this case, standard-size products will cause discomfort caused by long-term wearing by pressing on some parts of the ear canal or auricle of most users when worn. For example, many users will feel uncomfortable in their ears after wearing the device for 30 minutes or even less. In addition, although standard-size products improve the wearing firmness of the device by setting some protrusions, the improvement degree is limited, and there is still a problem that the device is easy to fall off. In the present invention, since the housing 500 of the customized in-ear wearable device 10 is customized for the user, it basically does not cause pressure on the user's ear. Therefore, compared with standard-size products, the customized in-ear wearable device 10 of the present invention improves the wearing comfort. Moreover, since the housing 500 is customized for the user, it has better fit with the user's ear (such as the external auditory canal), is firmly worn, and is not easy to fall off. In the case where both the wearing comfort and firmness are good, the user can wear the device for a longer time, for example, up to several hours or even longer. Further, since the user can wear the device for a longer time, the possibility of the user using it in various scenarios is increased. For example, in addition to regular audio-visual services, it can also be used for making or answering voice or video calls, playing games, performing various virtual reality activities, etc.

[0047] Figure 2FIG. 1 is an exploded view of a customized in-ear wearable device 10 according to an embodiment of the present invention. Figure 1 Similarly, the customized in-ear wearable device 10 according to this embodiment includes a panel assembly 100 and a customized housing 500. Figure 2 , the panel assembly 100 of this embodiment may include a panel 110, a mainboard 120, a control device 130, a charging device 140, a battery 150, an antenna device 160, a sound pickup device 180, a speaker assembly 190 and a wireless communication module 195 (not shown). The control device 130 is a touch panel that can be controlled above the panel 110, and the charging device 140 is a device that can charge the in-ear wearable device 10 from above the panel 110. The touch panel can be, for example, a device that realizes touch control by changing parameters such as resistance or capacitance of a touch unit on the touch panel through a finger or other body part. The difference between the touch panel and a mechanical control device such as a mechanical knob or a mechanical switch is that the touch panel usually does not produce visible mechanical movement to realize the control of the touch panel. In addition to using the technology of changing parameters such as resistance or capacitance, the present invention can also use other touch technologies as long as they can be controlled above the panel 110. The manipulation above the panel 110 mentioned herein may include operating the touch panel (manipulation device 130 ) through the panel 110 and partially exposing the touch panel from the panel 110 for manipulation.

[0048] In the case of a customized housing 500, the housing 500 is customized based on the user's ear, and its shape and size vary from user to user. Therefore, for the components of the customized in-ear wearable device 10 such as the control device 130, the charging device 140 and the sound pickup device 180 that need to interact with the outside world or need to be connected to the outside world, it is difficult to set the parts or interfaces that interact or connect with the outside world on the housing 500. In view of this, in the present invention, the parts or ports that interact or connect with the outside world of the control device 130, the charging device 140 and / or the sound pickup device 180 are set on the panel 110.

[0049] In the case of using a customized housing 500, if the panel 110 is too large, for example, much larger than the end of the customized housing 500 near the panel 110, or protrudes significantly from the user's ear (such as the concha and / or cymba conchae) when worn (for example, with a rod portion similar to that of a rod-shaped earphone), the wearing comfort and firmness of the user will be greatly reduced due to the large size and weight of the external part of the ear, and the noise (such as wind noise) will increase. In view of this, in the present invention, the panel 110 is designed to be substantially similar in shape to the end of the housing 500 near the panel 110. In other words, the panel 110 does not have a large protruding part relative to the housing 500, for example, no rod-shaped part protruding from the housing 500. In one embodiment, in the plane where the panel 110 or the control device 130 is located, the orthographic projection of the housing 500 covers all or most of the orthographic projection areas of the panel 110, the control device 130, the charging device 140, the battery 150, the antenna device 160, and the sound pickup device 180. Here, covering all the areas means that, in the plane where the panel 110 or the control device 130 is located, the orthographic projections of the panel 110, the control device 130, the charging device 140, the battery 150, the antenna device 160, and the sound pickup device 180 are within the orthographic projection range of the housing 500. Here, covering most of the areas means that, in the plane where the panel 110 or the control device 130 is located, more than 85% (including 85%) of the area defined by the outer contour of the orthographic projections of the panel 110, the control device 130, the charging device 140, the battery 150, the antenna device 160, and the sound pickup device 180 is within the orthographic projection range of the housing 500. The outer contour of the orthographic projections of multiple components can be the outer contour obtained by conventional methods, for example, the smallest contour line that can cover these multiple orthographic projections by using curves, broken lines, etc. along the outer edges of the multiple orthographic projections formed by the multiple components.

[0050] As described above, when the size of the panel 110 cannot be too large, how to accommodate the parts or ports where components such as the control device 130, the charging device 140, and / or the sound pickup device 180 interact or communicate with the outside world on the panel 110 becomes one of the problems to be solved urgently in the present invention.

[0051] For example, in the present invention, by using a touchpad as the control device 130 and a charging device 140 that partially overlaps the orthographic projection of the control device 130 in a direction perpendicular to the control device 130 and at least partially overlaps the minimum circumscribed circle of the orthographic projection of the control device in a direction parallel to the control device, the space occupied by the control device 130 and the charging device 140 on the panel 110 and in the housing 500 is reduced, so that the size of the panel assembly 100 and the in-ear wearable device 10 is reduced while enabling the control device 130 and the charging device 140 to work properly, and the adaptability rate of the panel assembly 100 and the wearing comfort of the device are improved.

[0052] In one embodiment, in a plane perpendicular to the plane of the panel 110 or the control device 130, the orthographic projection of the control device 130 and the orthographic projection of the charging device 140 partially overlap. For example, in a direction perpendicular to the panel 110 or the control device 130, the charging device 140 passes through the control device 130, or passes through a part or the outside of the control device 130. In the plane where the panel 110 or the control device 130 is located, the minimum circumscribed circle of the orthographic projection of the control device 130 and the minimum circumscribed circle of the orthographic projection of the charging device 140 at least partially overlap.

[0053] The minimum circumscribed circle of one or more shapes refers to the smallest circle that can accommodate these one or more shapes in a plane. For example, the minimum circumscribed circle of the orthographic projection of the control device 130 in the plane where the panel 110 is located refers to the smallest circle in the plane where the upper surface, lower surface or overall surface of the panel 110 (for example, a plane passing through the center or centroid of the panel 110 and substantially parallel to the whole panel) is located or a plane parallel to one of these planes, in which all the shapes formed by the orthographic projection of the control device 130 (the projection in the direction perpendicular to the aforementioned plane serving as the projection reference) are located. The upper surface of the panel 110 refers to the surface located outside when the panel 110 is installed on the housing 500, or the surface facing the outside of the user's ear when the in-ear wearable device 10 is worn by the user. The lower surface of the panel 110 is the surface on the opposite side of the upper surface. The upper surface and lower surface of other components have similar meanings. Similarly, the minimum circumscribed circle of the orthographic projection of the control device 130 in the plane where the control device 130 is located refers to the smallest circle in the plane where the upper surface, lower surface or overall surface of the control device 130 (for example, a plane passing through the center or centroid of the control device 130 and substantially parallel to the whole control device) is located or a plane parallel to one of these planes, in which all the shapes formed by the orthographic projection of the control device 130 (the projection in the direction perpendicular to the aforementioned plane serving as the reference) are located. In Figure 2 In the illustrated embodiment, when the plane where the control device 130 is located is used as the projection reference and the outer contour of the control device 130 is circular, the minimum circumscribed circle of the orthographic projection of the control device 130 is the circle serving as the outer contour of the control device 130. The minimum circumscribed circle of the orthographic projection of the charging device 140 is similar to that of the control device 130 and will not be elaborated here.

[0054] In one embodiment, in the plane where the panel 110 or the control device 130 is located, the minimum circumscribed circle of the orthographic projection of the charging device 140 can be located inside the minimum circumscribed circle of the orthographic projection of the control device 130 (and vice versa), the two can completely coincide (same size and position), or the minimum circumscribed circle of the orthographic projection of the charging device 140 can partially overlap with the minimum circumscribed circle of the orthographic projection of the control device 130.

[0055] In one embodiment, the overlapping rate can be used to represent at least partial overlap of the minimum circumscribed circles of the orthographic projections of the manipulation device 130 and the charging device 140 in the plane of the panel 110 or the plane where the manipulation device 130 is located. Assume that in the plane of the panel 110 or the plane where the manipulation device 130 is located, the area of the minimum circumscribed circle of the orthographic projection of the manipulation device 130 is S 1 , and the area of the minimum circumscribed circle of the orthographic projection of the charging device 140 is S 2 , and the area of the overlapping part of these two minimum circumscribed circles is S 0 , then the overlapping rate R of the minimum circumscribed circle of the orthographic projection of the manipulation device 130 and the minimum circumscribed circle of the orthographic projection of the charging device 140 is:

[0056]

[0057] In the above formula, max(S 1 , S 2 ) represents the larger value of S 1 and S 2 . In one embodiment, the overlapping rate R is 70% - 100%. When the two minimum circumscribed circles completely coincide, the overlapping rate R is 100%. In one embodiment, the overlapping rate R is 85% - 100%.

[0058] In one embodiment, the panel assembly 100 may further include a magnet 170, and the orthographic projections of the manipulation device 130 and the charging device 140 on a cross-section of the magnet 170 are located within this cross-section. In this case, the outer contours of the manipulation device 130 and the charging device 140 are smaller than the cross-section of the magnet 170. In one embodiment, as Figure 2 shown, the magnet 170 may be located between the main board 120 and the charging device 140. In one embodiment, the sound pickup device 180 may include a first sound pickup device 181 and a second sound pickup device 182. Although in Figure 2 the sound pickup device 180 is shown as including two sound pickup devices 181 and 182, in other embodiments, more or fewer sound pickup devices may also be employed according to actual requirements. As an example, the sound pickup device may be a microphone such as a microelectromechanical microphone (also known as a silicon microphone).

[0059] The in-ear wearable device may include at least one of an ear insertion detection sensor, a body temperature sensor, a blood pressure sensor, a blood oxygen sensor, a heart rate sensor, and a blood glucose sensor. In one embodiment, the customized in-ear wearable device 10 may include an ear insertion detection sensor 600 for detecting whether the customized in-ear wearable device 10 is in a worn state. When the ear insertion detection sensor 600 detects that the customized in-ear wearable device 10 is in a non-worn state, it may send this signal (i.e., the signal indicating that the customized in-ear wearable device 10 is in a non-worn state) to the control unit of the customized in-ear wearable device 10 to set the customized in-ear wearable device 10 to a standby state, other non-working states, or turn it off; while when it detects that the customized in-ear wearable device 10 is in a worn state, it may send this signal (i.e., the signal indicating that the customized in-ear wearable device 10 is in a worn state) to the control unit of the customized in-ear wearable device 10 to set the customized in-ear wearable device 10 to a working state, turn it on if the customized in-ear wearable device 10 was originally off, or continue to maintain the working state if it was originally in a working state. The ear insertion detection sensor 600 may be included in the panel assembly 100 or may be a component independent of the panel assembly 100. The ear insertion detection sensor 600 may use one or more of light detection, infrared detection, pressure detection, etc. to implement the detection of the worn state of the in-ear wearable device, and the present invention does not limit this.

[0060] In one embodiment, the customized in-ear wearable device 10 may include other types of sensors to replace the ear insertion detection sensor 600, or in addition to the ear insertion detection sensor 600, the customized in-ear wearable device 10 may further include other types of sensors. These other types of sensors may include a body temperature sensor, a blood pressure sensor, a blood oxygen sensor, a heart rate sensor, a blood glucose sensor, and so on. In one embodiment, multiple detections may be implemented using one type of sensor. For example, a single ear insertion detection sensor 600 using the infrared detection method can perform both worn state detection and body temperature detection. In one embodiment, a single detection may be implemented using multiple types of sensors. For example, the worn state detection may be performed using both a body temperature sensor and a heart rate sensor.

[0061] Although in this specification, the panel assembly 100 is illustrated as including the panel 110 and various components, it is not required that the panel 110 and the various components be formed as an integral whole, and they can be separately arranged according to circumstances. For example, the panel 110 can be assembled with some components into a first part, and other components into a second part, and these two parts are installed into the housing 500 at the later assembly stage of the customized in-ear wearable device 10. For example, the panel 110, the control device 130, the charging device 140, and the battery 150 can be arranged in one module, and other components in another module. Of course, other arrangement methods can be adopted, and the present invention does not limit this. Figure 3 is a component assembly diagram of the panel assembly 100 according to an embodiment of the present invention. Although the panel assembly 100 includes the panel 110, the panel 110 is not shown in Figure 3 for clarity. As Figure 3 shown, the various components can be assembled together by means such as bolts, welding, gluing, snap-fitting, etc.

[0062] Return to reference Figure 2 , components such as the main board 120, the control device 130, the charging device 140, the battery 150, the antenna device 160, the magnet 170, the sound pickup device 180, the speaker assembly 190, and the wireless communication module 195 can be located in the space formed by the panel 110 and the customized housing 500. Specifically, these components can mainly be located in the inner cavity 501 of the customized housing 500, and the panel 110 can be used to enclose the inner cavity 501. The panel 110 can be a flat cover plate, or an uneven or other non-flat cover plate, as long as it enables other components to work properly.

[0063] In the present invention, the adaptation rate of the panel assembly 100 refers to the proportion of the number of users for which the panel assembly 100 can be adapted to the customized in-ear wearable device 10 manufactured for them among the total number of users counted for a certain number of users. For example, if the size of the panel 110 is too large, the panel assembly 100 cannot be matched to the housing 500 customized for the user and the user's ear, and this situation is a non-adaptation. The calculation of the adaptation rate can adopt simple mathematical methods or any other statistical methods. The present invention designs the layout of the control device 130 and the charging device 140, reducing the space occupied by the control device 130 and the charging device 140 on the panel 110 and in the housing 500, thereby reducing the size of the panel assembly 100 and the customized in-ear wearable device 10 while enabling the control device 130 and the charging device 140 to work properly, and improving the adaptation rate of the panel assembly 100 and the wearing comfort of the device.

[0064] Return to reference Figure 2, continue to describe the customized in-ear wearable device 10 according to an embodiment of the present invention. In one embodiment, the orthographic projections of the main board 120, the control device 130, the charging device 140, the battery 150, the antenna device 160, the magnet 170, the sound pickup device 180, the speaker assembly 190, and the wireless communication module 195 on the plane where the panel 110 is located are located within the panel 110. As mentioned above, the panel 110 can be a flat cover plate, or an uneven or other non-flat cover plate. In the case where the panel 110 is uneven or other non-flat cover plate, the plane where the panel 110 is located is the approximate plane that the panel 110 can form, and it is not required that most of it be in this plane. For example, the parts above and below this plane of the panel 110 can be the same or similar. The reason for arranging the above-mentioned components so that their orthographic projections are located within the panel 110 is mainly to enable the panel 110 to cover each component, so that the panel 110 can easily form the panel assembly 100, which is convenient for it to be installed together with the customized housing 500. If the orthographic projection of one or more components protrudes outside the panel 110, that is, the panel 110 cannot cover this one or more components, there may be problems such as being unable to install it into the customized housing 500 due to the protrusion of the component or causing the component to be knocked and affecting the electrical connectivity of the component.

[0065] As Figure 2 shown, in one embodiment, the control device 130, the magnet 170, the main board 120, and the battery 150 can be sequentially arranged below the panel 110. By setting it in this way, each component can be better accommodated in the inner cavity 501 of the customized housing 500. This is particularly important for the customized in-ear wearable device 10, because different from the non-customized in-ear wearable device that can be provided with a relatively large external rod part or bean part, the customized in-ear wearable device 10 only has a small amount of protrusion in the direction perpendicular to the ear (that is, in the direction substantially perpendicular to the panel 110 when wearing the customized in-ear wearable device 10) (for example, the panel 110 and a small part of the customized housing 500), and there is basically no protrusion in the direction parallel to the ear (that is, in the direction parallel to the panel 110 when wearing the customized in-ear wearable device 10). Therefore, the volume of the inner cavity 501 of the customized housing 500 is very small, and the position and order of each component need to be fully designed to accommodate each component in the inner cavity 501.

[0066] As Figure 2As shown, in one embodiment, the control device 130 is a touchpad that can be operated above the panel 110. The control device 130 can be generally circular or oval, or other shapes can also be adopted. The control device 130 (touchpad) being generally circular or oval means that the overall outer contour of the control device 130 is circular or oval. There may be some through holes or depressions on the control device 130, but this does not affect the overall outer contour shape of the control device 130. Those skilled in the art can easily determine the general shape of the control device 130.

[0067] By operating through a touchpad instead of a mechanical knob or mechanical switch, the user can control the customized in-ear wearable device 10 by applying a relatively small force, thus reducing the pressure on the ears caused by manipulation when the user wears the device. At the same time, since the touchpad has a long service life and high stability, the failure rate of the control device 130 is also reduced. The touchpad can adopt a conventional resistive or capacitive touchpad, or other touch technologies can also be used. The present invention does not limit this.

[0068] In one embodiment, the diameter of the minimum circumscribed circle of the control device 130 (touchpad) can be 5 - 8 mm. In this size case, it can not only ensure normal and reliable touch of the control device 130 (touchpad) (it is impossible to achieve normal touch if it is too small), but also will not cause the panel 110 to be too large due to occupying too much space on the panel, resulting in a reduction in the adaptation rate of the panel assembly 100 and the wearing comfort of the device. At the same time, in this size case, through holes or depressions can be provided on the control device 130 to allow the charging device 140 to pass through. In one embodiment, the diameter of the minimum circumscribed circle of the control device 130 is 5 - 6 mm. In this case, the adaptation rate of the panel 110 and the wearing comfort of the device are further improved.

[0069] The through holes and depression parts of the control device 130 can adopt various shapes. For example, the through holes can be circular holes, oval holes or arc holes, and the depression parts can be arc depressions or depressions of other shapes.

[0070] The operation of the control device 130 can control the switch, working mode, on / off and mode of noise reduction, adjustment of volume size, and start, pause, previous track, next track, fast forward, rewind, etc. of audio / video playback of the customized in-ear wearable device 10. The working modes of the customized in-ear wearable device 10 can be, for example, Hi-Fi (high-fidelity) music mode, call mode, transparent mode, etc. For example, in the Hi-Fi music mode, the audio output mode is adjusted to a mode suitable for playing music and maximum noise reduction is turned on, so that users can obtain a good music experience; in the call mode, the voice is enhanced and appropriate noise reduction is turned on, so that users can make clear voice or video calls; in the transparent mode, external sounds are transmitted to the ears and noise reduction is not turned on, so that users can normally perceive external sounds as if they are not wearing the device, and thus can interact with the outside or others normally. The noise reduction modes can include, for example, maximum noise reduction, appropriate noise reduction, and no noise reduction, and can also include various noise reduction modes defined according to application scenarios, such as airplane noise reduction, high-speed rail noise reduction, subway noise reduction, office noise reduction, etc. The specific control content is not limited to the above, and can also include other content, and the control content can be preset or user-defined.

[0071] In one embodiment, the charging device 140 is a charging pin that can charge the customized in-ear wearable device 10 from above the panel 110. As Figure 2 shown, the charging device 140 can include multiple charging pins, which, for example, extend into the opening of the panel 110 through the control device 130. The multiple charging pins can contact the metal contacts of the charger or charging base from above the panel through the opening in the panel 110 to charge the customized in-ear wearable device 10.

[0072] The control device 130 can include through holes and / or recesses for the multiple charging pins to pass through. In one embodiment, as Figure 2 shown, the control device 130 includes a first through hole 131 at the center and a second through hole 132 at a non-center position. In this embodiment, the control device 130 includes 1 first through hole 131 and 3 second through holes 132. In other embodiments, the control device 130 can include other numbers of first through holes 131 and second through holes 132, such as 1 first through hole 131 and 1 second through hole 132, 1 first through hole 131 and 2 second through holes 132, 2 first through holes 131 and 1 second through hole 132, 2 first through holes 131 and 2 second through holes 132, etc. The positions of the first through hole 131 and the second through hole 132 can be set in various ways according to requirements. For example, when the control device 130 includes 1 first through hole 131 and 1 second through hole 132, the first through hole 131 and the second through hole 132 can be symmetric about the center of the control device 130. Of course, an asymmetric setting can also be adopted. In one embodiment, asFigure 2 As described above, when the control device 130 includes one first through hole 131 and three second through holes 132, the second through holes 132 are arranged in an equilateral triangle with the first through hole 131 as the center. The number and position settings of the through holes of the control device 130 are described above. However, those skilled in the art understand that the number and position of the through holes can be determined based on the number and position of the charging pins. In other words, the number of through holes can be equal to or greater than the number of charging pins, and the through holes corresponding to the charging pins are arranged at positions where the charging pins can pass through.

[0073] Although it is shown in Figure 2 that the charging pins extend into the panel 110 through the through holes on the control device 130, the charging pins can also pass through the control device 130 in other ways, such as extending into the panel 110 through the recesses on the outer periphery of the control device 130 (touchpad), extending into the panel 110 through the outside of the outer contour of the control device 130, and so on.

[0074] Figure 4 is a schematic diagram of the control device 130 and the charging device 140 according to an embodiment of the present invention. As Figure 4 shown, recesses 133 are provided on the outer periphery of the control device 130 (touchpad) for multiple charging pins of the charging device 140 to pass through. Similar to the second through holes 132, the number of recesses 133 can be one or more. When there are multiple recesses 133, the recesses 133 can be evenly distributed on the outer periphery of the control device 130 or unevenly distributed on the outer periphery of the control device 130. The position where the charging pins pass through the control device 130 can be within the outer contour of the control device 130 without recesses, so that the presence of the charging device 140 does not cause an increase in the size of the panel 110. In Figure 4 the shown embodiment, in addition to including the recesses 133, the control device 130 further includes one first through hole 131. In one embodiment, the control device 130 can only include the recesses 133 and not include any through holes. In one embodiment, the control device 130 can include at least one of through holes, recesses, the outside of the outer contour, etc.

[0075] By forming through holes or recesses in the control device 130 for the charging pins to pass through, the arrangement of the control device 130 and the charging device 140 can be made more compact, thereby further reducing the space occupied by these components on the panel 110 and within the housing 500. Thus, when the control device 130 and the charging device 140 can work normally, the size of the panel assembly 100 and the customized in-ear wearable device 10 can be reduced, improving the adaptability rate of the panel assembly 100 and the wearing comfort of the device.

[0076] Figure 5Schematic diagram of the control device 130 and the charging device 140 according to an embodiment of the present invention. In one embodiment, as Figure 5 shown, multiple charging pins of the charging device 140 can be arranged near the outer contour of the control device 130 without forming through holes or recesses in the control device 130. In this case, the minimum distance between the multiple charging pins and the outer contour of the control device 130 is, for example, within 2 mm (e.g., 0.5 - 2 mm), so as to avoid problems such as loose component layout due to excessive distance or excessive space occupation on the panel 110 and within the housing 500.

[0077] In the present invention, multiple charging pins of the charging device 140 can extend into the opening of the panel 110 through one, two, or all of the through holes, recesses, and the outside of the outer contour of the control device 130. In one embodiment, as Figure 2 shown, multiple charging pins of the charging device 140 all extend into the opening of the panel 110 through the through holes on the control device 130. In one embodiment, multiple charging pins of the charging device 140 all extend into the opening of the panel 110 through the recesses on the control device 130. In one embodiment, as Figure 5 shown, multiple charging pins of the charging device 140 all extend into the opening of the panel 110 from outside the outer contour of the control device 130, and no through holes or recesses are provided on the control device 130. In one embodiment, as Figure 4 shown, at least one charging pin of the charging device 140 extends into the opening of the panel 110 through the through hole on the control device 130, and other charging pins extend into the opening of the panel 110 through the recesses on the control device 130. In one embodiment, at least one charging pin of the charging device 140 extends into the opening of the panel 110 through the through hole or recess on the control device 130, and other charging pins are arranged near the outside of the outer contour of the control device 130. In one embodiment, at least one charging pin of the charging device 140 extends into the opening of the panel 110 through the through hole on the control device 130, at least one charging pin extends into the opening of the panel 110 through the recess on the control device 130, and other charging pins are arranged near the outside of the outer contour of the control device 130.

[0078] Figure 6 Schematic diagram of the control device 130 and the charging device 140 according to an embodiment of the present invention. In Figure 6 the shown embodiment, the control device 130 is configured as a ring, and all charging pins of the charging device 140 extend into the opening of the panel 110 through the inside of the ring. In other embodiments, it is also possible to adopt a method in which some charging pins extend into the panel 110 through the inside of the ring, while other charging pins extend into the panel 110 through at least one of the through holes, recesses, and the outside of the outer contour.

[0079] The multiple charging pins of the charging device 140 can extend out from the openings in the panel 110, that is, the upper ends of the charging pins can be higher than the upper surface of the panel 110. In this case, the charging pins can make good contact with the metal contacts of the charger or the charging dock. However, it may affect the touch operation of the control device 130. Therefore, in one embodiment, the charging pins may not extend out from the openings in the panel 110, that is, the upper ends of the charging pins can be flush with the upper surface of the panel 110 or lower than the upper surface of the panel 110, so as not to affect the touch operation of the control device 130 due to the protrusion of the charging pins from the panel 110. When the upper ends of the charging pins are lower than the upper surface of the panel 110, the upper ends of the charging pins can be set to be slightly lower than the upper surface of the panel 110. For example, when the thickness of the panel 110 is 1 mm, the distance between the upper ends of the charging pins and the upper surface of the panel 110 in the direction perpendicular to the upper surface of the panel 110 can be 0.1 - 0.8 mm. In this case, the upper ends of the charging pins are set to be higher than the lower surface of the panel 110, and the openings in the panel 110 can be used to limit the charging pins, thereby further improving the contact reliability between the charging pins and the metal contacts of the charger or the charging dock.

[0080] When the upper ends of the charging pins are lower than the upper surface of the panel 110, the metal contacts of the charger or the charging dock that cooperate with the charging pins need to be able to extend into the openings in the panel 110 for accommodating the charging pins to contact the charging pins. In one embodiment, the upper ends of the multiple charging pins are all flush with the upper surface of the panel 110. In one embodiment, the upper ends of the multiple charging pins are all lower than the upper surface of the panel 110. In one embodiment, the upper ends of at least one of the multiple charging pins are flush with the upper surface of the panel 110, and the upper ends of the other charging pins are lower than the upper surface of the panel 110. The "upper ends of the charging pins" mentioned here refer to the ends of the charging pins extending into the openings in the panel 110, or the ends close to the upper surface of the panel 110.

[0081] The number of charging pins can be 2, or other numbers greater than 2, such as 3, 4, etc. The multiple charging pins can include at least one charging pin of the first polarity (such as positive or negative) and at least one charging pin of the second polarity (such as negative or positive). The charging pin of the first polarity can extend into the opening in the panel 110 through the first through hole at the center of the control device 130, and the charging pin of the second polarity can extend into the opening in the panel 110 through the second through hole or the recess of the control device 130. The number of the second through holes or the recesses can be one or more. In one embodiment, the number of the charging pins of the first polarity is 1, and the number of the charging pins of the second polarity is 3. In one embodiment, the 3 charging pins of the second polarity are arranged in an equilateral triangle with the charging pin of the first polarity as the center. The charging pins of the same polarity are usually electrically connected, for example, electrically connected through wires or metal sheets.

[0082] In one embodiment, as Figure 2 shown, the charging device 140 includes four charging pins. One charging pin of the positive electrode can be located in the middle, for example, corresponding to the center of the control device 130, the battery 150, or the magnet 170; three charging pins of the negative electrode can be equally spaced around the positive charging pin. Setting multiple charging pins for a certain polarity can improve the connection reliability with the charger or charging base, that is, even if some charging pins have poor contact with the corresponding contacts of the charger or charging base due to problems such as stains, rust, or insufficient height, electrical connection can still be achieved through other charging pins. In another embodiment, the positive and negative charging pins can be interchanged. For example, there is one charging pin for the negative electrode and three charging pins for the positive electrode. In other embodiments, other numbers of charging pins can also be used, such as one positive charging pin and two negative charging pins, or two positive charging pins and one negative charging pin, etc. The thickness of the positive charging pin and the negative charging pin can be the same or different. For example, in the case where the charging pins include one positive charging pin and three negative charging pins, the positive charging pin can be set to be thicker than the negative charging pins, so as to improve the connection reliability of the charging pins with fewer numbers and ensure the impedance consistency of charging pins with different polarities. The charging pins can have a fixed height or a certain elasticity, so as to better connect when contacting the contacts of the charger or charging base.

[0083] The charging pins can be in the shape of dots or small circles when viewed from above the panel, or can be in various shapes such as straight line segments, arc line segments, broken line segments, and curve segments when viewed from above the panel. Figure 7 is a perspective view of the customized in-ear wearable device 10 according to an embodiment of the present invention. In this embodiment, the charging pins are arc-shaped pieces, and the panel is provided with arc-shaped openings allowing the charging pins to extend in. This is shown in FIG. 7 as an arc line segment with a certain thickness. By setting the radian and thickness, the connection reliability between the charging pins and the charger or charging base can be improved. Similar to the previous description, these multiple arc-shaped charging pins can extend into the openings on the panel through the through holes, recesses on the control device, or outside the outer contour of the control device, and other settings are similar, and the description thereof is omitted here. In one embodiment, multiple charging pins are arranged in an arc shape outside the control device. The minimum distance between these multiple charging pins and the outer contour of the control device can also be within 2 mm, for example, 0.5 - 2 mm.

[0084] Return to reference Figure 2, in one embodiment, a support plate may be provided to fix the charging pins. In other embodiments, other methods may also be used to fix the charging pins. In the case where there are more than one charging pin on the same electrode, these charging pins may be electrically connected by a conductive metal sheet or metal wire, and the metal sheet or metal wire may be fixed to the support plate as well, for example. In the present invention, for clarity, the charging device 140 generally refers to the charging pins and does not include the support plate and the metal sheet or metal wire used as the electrical connection mechanism. Specifically, when referring to the orthographic projection, outer contour or minimum circumscribed circle of the charging device 140 in this application, it only refers to the orthographic projection, outer contour or minimum circumscribed circle of the charging pins, and does not include other parts such as the support plate and the metal sheet / metal wire.

[0085] The battery 150 provides the power required for the operation of the customized in-ear wearable device 10. It may use a rechargeable battery of a specific specification, such as a 1054-type (i.e., with a cross-sectional diameter of 10 mm and a height of 54 mm) rechargeable battery, or other specifications of rechargeable batteries. The battery 150 may be a lithium-ion battery or other types of batteries, and the present invention does not limit this.

[0086] The antenna device 160 is used to send and receive wireless signals for the customized in-ear wearable device 10, enabling the customized in-ear wearable device 10 to work in a wireless manner. The antenna device 160 may be located, for example, at a position close to the lower side of the panel 110 when the customized in-ear wearable device 10 is worn, so that the antenna device 160 is not blocked by other metal components and is as far away from other metal components as possible to better send and receive wireless signals. The antenna device 160 may be in various forms such as a dipole antenna, a planar inverted-F antenna, a ceramic antenna, etc., and the present invention does not limit this.

[0087] The magnet 170 is used to stably suck the customized in-ear wearable device 10 to the charger or charging base when the customized in-ear wearable device 10 is charged, thereby improving the charging connection stability. In one embodiment, the magnet 170 may be a circular magnet. In this case, its center may coincide with the center of the control device 130 or the battery 150. Although only one circular magnet is shown in Figure 2 , those skilled in the art can understand that other numbers and other shapes of magnets may also be used. For example, the customized in-ear wearable device 10 may not include the magnet 170, or two or more magnets may be used. The multiple magnets may have different polarities, and the shape of the magnet may be various shapes such as circular, oval, square, etc. In the case where the customized in-ear wearable device 10 uses two magnets with different polarities, corresponding settings may also be made on the charger or charging base, so that the customized in-ear wearable device 10 and the charger or charging base can be better abutted against each other.

[0088] The main board 120 is used to load and connect the main components of the customized in-ear wearable device 10, and these components include a control device 130, a charging device 140, a battery 150, an antenna device 160, a sound pickup device 180, a speaker assembly 190, a wireless communication module 195, etc. These components can be directly or indirectly fixed to the main board 120 by means such as bolts, welding, gluing, etc. (for example, through various fixing components or through other components), and the connection of each component can be achieved through various means such as printed circuits, leads, flying wires, ball pins, etc. on the main board 120. In Figure 2 the illustrated embodiment, the main board 120 is a rigid main board, which can be arranged between the magnet 170 and the battery 150, and can also be arranged between the control device 130 and the battery 150 or between the support plate of the charging device 140 and the battery 150 in the absence of the magnet 170. In one embodiment, the customized in-ear wearable device 10 can adopt a flexible main board, and reference will be made Figure 8 to it for detailed description.

[0089] Returning to the reference Figure 2 , in one embodiment, the sound pickup device 180 can include two sound pickup devices 181 and 182. According to the functions of the customized in-ear wearable device 10, the sound pickup devices 181 and 182 can be used to pick up the same type of sound or different types of sound. For example, the first sound pickup device 181 can be used to pick up call sounds and ambient sounds, and the second sound pickup device 182 can be used to pick up ambient sounds. By using two or more sound pickup devices to pick up sounds, the sounds picked up by different sound pickup devices can be processed, so as to achieve effects such as sound or sound field enhancement and noise reduction. In other embodiments, other numbers of sound pickup devices 180 can also be adopted, such as one, three or more. The sound pickup device 180 can be any type of sound pickup device suitable for in-ear wearable devices, such as a microphone like a microelectromechanical microphone.

[0090] The speaker assembly 190 can include a sound output device for outputting sounds for the customized in-ear wearable device 10, and the sound output device can be a balanced armature speaker or a dynamic speaker, a hybrid speaker, etc. In order to enable the sound output by the sound output device of the speaker assembly 190 to enter the ear canal of the user wearing the customized in-ear wearable device 10, an opening is usually provided on the customized housing 500 of the customized in-ear wearable device 10 to allow the sound to pass through. In one embodiment, the speaker assembly 190 can also include a third sound pickup device for detecting the frequency response characteristics of the sound output by the sound output device of the speaker assembly 190, so as to adjust the output of the sound output device based on the frequency response characteristics.

[0091] The wireless communication module 195 is used to process the signals of the customized in-ear wearable device 10 so that it can perform wireless communication. The wireless communication module 195 can be provided on the main board 120 or at other positions. The wireless communication module 195 can be a Bluetooth module or other types of wireless communication modules, as long as it can achieve the wireless operation of the customized in-ear wearable device 10. The wireless communication module 195 can be integrated into the central processing unit (CPU) of the customized in-ear wearable device 10 or be a separate module.

[0092] As described above, the customized housing 500 can be manufactured by taking an ear mold of the user's ear and then manufacturing based on the taken ear mold. The manufacturing method can be 3D printing or other manufacturing methods. In one embodiment, the customized in-ear wearable device 10 may further include a ventilation duct provided in the customized housing 500 for ventilation when the user wears the customized in-ear wearable device 10. One end of the ventilation duct can be located at the protruding part of the customized in-ear wearable device 10 that extends into the external auditory canal, and the other end can be located at a part of the customized housing 500 close to the panel 110, so that the ventilation duct can balance the air pressure between the ear canal and the external space when the user wears the customized in-ear wearable device 10 and reduce the discomfort caused by the increase in internal ear pressure or the imbalance between internal and external pressures.

[0093] In one embodiment, the customized housing 500 can include a first protruding part 510 and a second protruding part 520. When the user wears the in-ear wearable device 10, the first protruding part 510 can be located in the user's external auditory canal or in the concha and external auditory canal of the user's ear, and the second protruding part 520 can be located in the cymba conchae of the user's ear. Figure 8 It is a schematic diagram of the structure of the user's ear. Refer to Figure 8 and the description in this specification, it can be understood the positional relationship between each part of the customized in-ear wearable device 10 and the user's ear when the user wears the customized in-ear wearable device 10. The first protruding part 510 can include an opening, and the speaker assembly 190 is located inside the first protruding part near the opening. That is, the sound output by the sound output device of the speaker assembly 190 enters the user's ear canal through the opening of the first protruding part 510. In one embodiment, when the user wears the customized in-ear wearable device 10, the projection of the panel 110 in the direction of the user's ear is located within the ear contour. Here, the ear contour mainly refers to the outer contour of the ear (such as the helix) plus the range formed by the connection line between the ear and the face. In one embodiment, most (50% - 65%) of the projection of the panel 110 in the direction of the user's ear is located in the concha of the user's ear, a small part (30% - 45%) is located in the cymba conchae of the user's ear, and another small part is located within the range outside the concha and cymba conchae and within the ear contour.

[0094] Figure 9is an exploded view of a customized in-ear wearable device 20 according to an embodiment of the present invention. As Figure 9 shown, the customized in-ear wearable device 20 according to this embodiment includes a panel assembly 200 and a customized housing 500. The panel assembly 200 may include a panel 210, a main board 220, a control device 230, a charging device 240, a battery 250, an antenna device 260, a magnet 270, a sound pickup device 280, a speaker assembly 290, a wireless communication module 295 (not shown), etc. Except for the main board 220, Figure 9 the panel assembly 200, panel 210, control device 230, charging device 240, battery 250, antenna device 260, magnet 270, sound pickup device 280, speaker assembly 290, and wireless communication module 295 shown in Figure 2 may be similar to the panel assembly 100, panel 110, control device 130, charging device 140, battery 150, antenna device 160, magnet 170, sound pickup device 180, speaker assembly 190, and wireless communication module 195 shown in

[0095] As Figure 9 shown, the main board 220 may be a folding circuit board or a flexible circuit board, which may at least partially surround the battery 250. By adopting a folding circuit board or a flexible circuit board, the layout flexibility of each component can be improved, and the space occupied by each component can be reduced.

[0096] Although the technical solution of the present invention has been described in detail above with a customized in-ear wearable device, those skilled in the art can understand that a non-customized in-ear wearable device can also adopt the above technical solution. When the in-ear wearable device is non-customized, both the panel assembly and the housing can be non-customized components, that is, standard-size components. In the case of a non-customized in-ear wearable device, by adopting the technical solution of the present invention, the space occupied by components such as the control device and the charging device can also be reduced, thereby reducing the size of the panel assembly and the device.

[0097] Obviously, the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.

[0098] In addition, terms such as "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
