Description

Technical Field

[0001] The present invention relates to earphones, and more particularly to customized wireless earphones. Background Art

[0002] With the increasingly wide application scenarios of mobile devices such as smart phones and the increasing use of audio-visual services by people, wireless earphones have been rapidly popularized due to their advantages such as convenient carrying and no entanglement problems. TWS (True Wireless Stereo) Bluetooth earphones have become the mainstream products in wireless earphones due to their advantages such as short latency and good sound quality.

[0003] However, current TWS Bluetooth earphones are all standard-size earphones. Since the ear canal shapes and sizes of each user are different, the earphones are not satisfactory in terms of comfort, stability, sound insulation and noise reduction effects, etc., thus limiting the application scenarios of TWS Bluetooth earphones. Summary of the Invention

[0004] Current Bluetooth earphones mainly have two types: in-ear and semi-in-ear. In-ear earphones use earplugs of different models. The advantages are good physical sound insulation, good active noise reduction effect, and relatively good wearing stability, but the disadvantages are strong foreign body sensation and poor comfort. The advantages of semi-in-ear earphones are comfortable to wear, but the disadvantages are poor sound insulation, poor active noise reduction effect and easy to fall off and get lost. The present invention provides a third earphone form, effectively solving the problems of how to balance comfort, stability, sound insulation and noise reduction effects, etc.

The first side includes a first section, and the second side includes a second section. When the user wears the customized wireless earphone, the first section corresponds to the user's tragus, and the second section corresponds to the user's antitragus. The first side extends in a first direction of the panel; the length of the panel is 22.4 - 28.2 mm, and the width is 14.3 - 20.3 mm. Wherein, the length of the panel is the dimension of the panel in the first direction, and the width of the panel is the dimension of the panel in a second direction. The second direction is the direction perpendicular to the first direction on the panel.

[0006] In one embodiment, the first direction is the direction parallel to the connection line between the user's ear and the face or a direction having a certain angle with the connection line when the user wears the customized wireless earphone, and the angle is within 45°.

[0007] In one embodiment, the first angle formed by the second section and the first section, the first side or the first direction is 45° to 65°.

[0009] In one embodiment, the length of the panel is 23.9 - 26.1 mm, and the width is 15.0 - 17.2 mm.

[0010] In one embodiment, the panel further includes a third side, and the second side and the third side approach each other in a direction away from the first side.

[0011] In one embodiment, the second angle formed by the third side and the first section, the first side or the first direction is greater than the first angle.

[0012] In one embodiment, at least one of the first side, the second side and the third side is a straight line or a curve, and they are connected to each other through rounded corners or arcs.

[0013] In one embodiment, the panel is generally a rounded triangle or a D shape.

[0014] In one embodiment, the orthographic projections of the main board, the control device, the charging device, the battery, the antenna device, the sound pickup device, the speaker assembly and the wireless communication module on the plane where the panel is located are located within the panel.

[0015] In one embodiment, the customized wireless earphone further includes a magnet, wherein the control device, the magnet, the main board and the battery are arranged in sequence below the panel.

[0016] In one embodiment, the customized wireless earphone further includes a panel adapter, and the panel is installed on the customized housing through the panel adapter.

[0017] In one embodiment, the panel adapter and the customized housing are integrated.

[0018] In one embodiment, the control device is a touch pad that can be controlled above the panel, and the charging device is a charging pin or a metal coil that can charge the customized wireless earphone through the panel.

[0037] The following describes the detailed implementation manners of the present application with reference to the accompanying drawings. In each of the drawings, the same or similar reference numerals are used to represent the same or similar components, and their repeated descriptions are omitted for simplicity.

[0038] Figure 1 It is a perspective view of a customized wireless earphone 10 according to an embodiment of the present invention. In Figure 1 only one earphone (for example, the left earphone) is shown, but those skilled in the art understand that a pair of earphones usually consists of two earphones, the left and the right, whose structures are basically symmetrical and communicate wirelessly. Therefore, for simplicity, only one earphone is shown in the drawings, and the following description is also only for one earphone. Referring to Figure 1 , the customized wireless earphone 10 according to this embodiment includes a panel assembly 100 and a customized housing 500. The customized housing 500 can be, for example, made by taking an ear mold of a user's ear (including parts such as the external auditory canal, the concha cavity, and / or the cymba conchae), and then using manufacturing equipment to manufacture based on the taken ear mold. The manufacturing method can be, for example, 3D printing. The size of the customized housing 500 can 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.

[0039] Current wireless earphones are all standard-sized products. Due to the different shapes and sizes of each user's ear canals, standard earphones have problems such as uncomfortable wearing for users, easy detachment of the device, and poor sound insulation and noise reduction effects, thus limiting the wearing time and application scenarios of the earphones. In the case of standard earphones, in order to fit the ear sizes of most users (such as the concha), their sizes need to be as small as possible. However, in order to ensure stable wearing without falling off, some protrusions need to be set to firmly hold the earphones in place on the ears. In this case, standard earphones will exert pressure on some parts of the ear canals or auricles of most users during wearing, resulting in discomfort caused by long-term wearing. For example, many users will feel uncomfortable in their ears after wearing standard earphones for 30 minutes or even less. In addition, although standard earphones set some protrusions to improve wearing stability, the improvement is limited, and there is still a problem of easy detachment. At the same time, due to the low fitting degree between standard earphones and the ears (such as the concha and / or ear canal), there are problems of poor sound insulation and noise reduction effects. In the present invention, since the housing 500 of the customized wireless earphone 10 is customized for the user and basically does not exert pressure on the user's ears, compared with standard earphones, the customized wireless earphone 10 of the present invention improves wearing comfort, and the housing 500 fits well with the user's ears (such as the external ear canal), is stably worn, not easily detached, and has good sound insulation and noise reduction effects. In the case where the wearing comfort, stability, and sound insulation and noise reduction effects are all good, the user can wear the earphones for a longer time, for example, up to several hours or even longer. Further, since the user can wear the earphones for a longer time, the possibility of the user using them in various scenarios is increased. For example, in addition to regular audio-visual services, they can also be used for making or receiving voice or video calls, playing games, carrying out various virtual reality activities, etc.

[0040] Figure 2 is an exploded view of a customized wireless earphone 10 according to an embodiment of the present invention. Similar to Figure 1 , the customized wireless earphone 10 according to this embodiment includes a panel assembly 100 and a customized housing 500. Referring to Figure 2 , the panel assembly 100 may include a panel 110, a main board 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, a wireless communication module 195 (not shown), etc. In one embodiment, the panel assembly 100 may further include a magnet 170. In another embodiment, the panel assembly 100 may not include the magnet 170. 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 2The sound pickup device 180 is shown as including two sound pickup devices 181 and 182. However, in other embodiments, more or fewer sound pickup devices may 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).

[0041] In one embodiment, the customized wireless earphone 10 may further include an ear detection sensor 600 for detecting whether the customized wireless earphone 10 is in a worn state. When the ear detection sensor 600 detects that the customized wireless earphone 10 is in a non-worn state, it may send a signal (a signal indicating that the customized wireless earphone 10 is in a non-worn state) to the control unit (such as a central processing unit or a main control unit) of the customized wireless earphone 10 to set the customized wireless earphone 10 to a standby state, a paused working state, other non-working states, or to turn it off, etc.; while when it detects that the customized wireless earphone 10 is in a worn state, it may send a signal (a signal indicating that the customized wireless earphone 10 is in a worn state) to the control unit of the customized wireless earphone 10 to set the customized wireless earphone 10 to a working state, to turn it on if the customized wireless earphone 10 was originally off, or to continue to maintain the working state if it was originally in a working state, etc.

[0042] Although in this specification, the panel assembly 100 is illustrated as including the panel 110 and various components, this does not require the panel 110 and the various components to be formed as a single entity. They may be separately provided according to circumstances. For example, the panel 110 may be separated from other components and only installed together or separately installed into the housing 500 during the assembly stage of the customized wireless earphone 10. The various components may also be provided in different modules. For example, the manipulation device 130, the charging device 140, and the battery 150 may be provided in one module, and other components may be provided in another module. Of course, other setting methods may also be adopted, and the present invention does not limit this. Figure 3 is a partial component assembly diagram of the customized wireless earphone 10 according to an embodiment of the present invention. In Figure 3 it, the panel 110 is not shown for clarity. As Figure 3 shown, the components may be assembled together by means such as bolts, welding, gluing, snapping, etc.

[0043] 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 be mainly 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 other components can work properly. When the control device 130 is a touchpad operated through the panel 110, the panel 110 is usually a flat or nearly flat cover plate to ensure better operation of the touchpad.

[0044] Figure 4 is a top view of the panel 110 according to an embodiment of the present invention. As Figure 4 shown, the panel 110 can include a first side 111 and a second side 112. The first side 111 can include a first section 115, and the second side 112 can include a second section 116. When the user wears the customized wireless earphone 10, the first section 115 can correspond to the user's tragus, and the second section 116 can correspond to the user's antitragus. The first side 111 can extend in the first direction y of the panel 110.

[0045] The first side 111 can be the side close to the user's face when the user wears the customized wireless earphone 10, and the second side 112 can be the side close to the lower rear (antitragus) of the user's ear when the user wears the customized wireless earphone 10. Figure 7 is a schematic diagram of the structure of the user's ear, Figure 8 is a wearing schematic diagram of the customized wireless earphone 10 according to an embodiment of the present invention. Referring to Figure 7 and Figure 8 can better understand the state when the user wears the customized wireless earphone 10.

[0046] The first section 115 can correspond to the user's tragus, that is, the tragus close to the user's ear when the user wears the customized wireless earphone 10. In one embodiment, when the user wears the customized wireless earphone 10, the first section 115 can fit the user's tragus. In another embodiment, when the user wears the customized wireless earphone 10, the first section 115 can be at a certain distance from the user's tragus.

[0047] In one embodiment, referring to Figure 4, the first section 115 can be curved, with a slight depression in the middle to better fit the user's tragus, thereby improving the user's wearing comfort, stability, and sound insulation and noise reduction effects. When the first section 115 is curved, it can be the part on the first side 111 corresponding to the tragus of the user's ear. When both sides of the first section 115 are convex, that is, when both the middle and the lower side ( Figure 4 shown below) of the first side 111 are convex, the two end points on both sides of the first section 115 can correspond to the vertices of these two convexities. In one embodiment, the first section 115 can mainly be the lower half of the first side 111. In one embodiment, the first section 115 and even the first side 111 can be straight lines.

[0048] The second section 116 can correspond to the antitragus of the user, that is, the antitragus close to the user's ear when the customized wireless earphone 10 is worn. In one embodiment, when the customized wireless earphone 10 is worn by the user, the second section 116 can fit the antitragus of the user. In another embodiment, when the customized wireless earphone 10 is worn by the user, the second section 116 can be at a certain distance from the antitragus of the user.

[0049] In one embodiment, referring to Figure 4 , the second section 116 can be curved, with a slight depression in the middle to better fit the antitragus of the user, thereby improving the user's wearing comfort, stability, and sound insulation and noise reduction effects. When the second section 116 is curved, it can be the part on the second side 112 corresponding to the antitragus of the user's ear. When both sides of the second section 116 are convex, the two end points on both sides of the second section 116 can correspond to the vertices of these two convexities. In one embodiment, the second section 116 can be the main part of the second side 112, such as the part of the second side 112 except for the rounded corners or arcs used for connection. In one embodiment, the second section 116 can be a straight line.

[0050] In one embodiment, as Figure 4 shown, the panel 110 can further include a third side 113. The second side 112 and the third side 113 are connected to the first side 111 by rounded corners or arcs and approach each other in the direction away from the first side 111. The first side 111 can extend in the first direction y. The second side 112 and the third side 113 can be connected to both ends of the first side 111 by rounded corners or arcs, extend in a direction at a certain angle (less than 90°) to the first direction y, approach each other in the direction away from the first side 111, and are connected to each other by rounded corners or arcs. In one embodiment, the second side 112 and the third side 113 can be integrally arc-shaped. In one embodiment, the panel 110 is D-shaped, with the first side 111 forming a straight side and the second side 112 and the third side 113 jointly forming an arc-shaped side.

[0051] The first direction y of the panel 110 can be a direction that is substantially parallel to the connection line between the user's ear and the face when the user wears the customized wireless earphone 10, or a direction that forms a certain angle with the connection line between the user's ear and the face. For example, this angle can be within 45°. In one embodiment, this angle can be within 30°. In one embodiment, the first direction y can be consistent with the direction of the first side 111 or the first section 115. The second direction x of the panel 110 can be a direction perpendicular to the first direction y on the panel 110. As Figure 8 shown, when the user wears the customized wireless earphone 10, the first direction y or the first side 111 is substantially parallel to the connection line IL1 between the user's ear and the face. The connection line IL1 between the user's ear and the face can be the line segment at the root of the tragus or the line segment at the root of the ear. It is a substantially straight line segment where the ear meets the face on the side close to the face, and is only used herein to assist in explaining the direction of the first side 111.

[0052] When the main body of the first side 111 is approximately a straight line segment, the first direction y is basically consistent with the direction of the first side 111. When the user actually wears the customized wireless earphone 10, the side of the first side 111 close to the user's face can be substantially parallel to the direction of the connection line between the user's ear and the face, or in other words, substantially parallel to the direction of the root of the ear or the root of the tragus. The second side 112 is located at the rear lower side (close to the antitragus), and the third side 113 is located at the rear upper side (close to the antihelix), that is, the second side 112 and the third side 113 are located at positions farther from the user's face compared to the first side 111. In other words, when the user wears the customized wireless earphone 10 in the standing position, the first direction y is a substantially vertical direction, that is, a direction substantially perpendicular to the ground. Due to the differences in the ear structures and shapes of different users, the first direction y may also form a certain angle with the vertical direction, for example, within 45°. In one embodiment, the angle between the first direction y and the vertical direction is within 30°. The second direction x is substantially perpendicular to the first direction y. According to the state of the user when wearing, when the first direction y is a substantially vertical direction, the second direction can be a front-back horizontal direction (a backward horizontal direction opposite to the direction of the face), or can be a side-rear horizontal direction (a side-rear horizontal direction opposite to the direction of the face but biased towards the outside of the body). Of course, due to the differences in the ear structures and shapes of different users and the differences in the standing postures of the users, the first direction y and the second direction x may form a certain angle with the directions pointed out above, for example, within 45°.

[0053] Return to reference Figure 4 In one embodiment, the panel 110 is substantially a rounded triangle or a D shape. For example, the first side 111 can correspond to the straight side of the D shape, and the second side 112 and the third side 113 can jointly correspond to the curved side of the D shape. Although in Figure 4Among them, the first side 111, the second side 112, and the third side 113 are shown as curves close to straight lines and are connected by rounded corners or arc segments, but the present invention is not limited thereto. At least one of the first side 111, the second side 112, and the third side 113 may be a straight line or a curve, and they are connected to each other by rounded corners or arcs. In one embodiment, the first side 111, the second side 112, and the third side 113 may all be straight lines or curves, and they are connected to each other by rounded corners or arcs. For example, the first side 111, the second side 112, and the third side 113 may be straight lines, or have a greater curvature compared to the Figure 4 shown shape, and their convex directions may also be different. For example, each side may have at least one convexity and / or at least one concavity. In one embodiment, at least one of the first side 111, the second side 112, and the third side 113 is a straight line, and the others are curves. For example, the first side 111 is a straight line, and the second side 112 and the third side 113 are curves. In addition to rounded corners or arc segments, the connection of the first side 111, the second side 112, and the third side 113 can also be achieved by at least one broken line segment or other shaped line segments.

[0054] Based on the shapes obtained by taking ear molds from a large number of users, in order to improve the wearing comfort, stability, sound insulation and noise reduction effects of the earphones, as well as the adaptation rate of the panel components, the first side 111 can preferably be designed as a curve with a convexity in the middle, depressions on both sides of the middle convexity, and then convexities on both sides of the depressions but with a smaller curvature. Refer to Figure 4 and Figure 7 , the two depressions can respectively correspond to the tragus and the crus of helix, and the three convexities can respectively correspond to the lower convexity, the left convexity of the cymba conchae, and the left convexity of the cavum conchae; the second side 112 can be designed as a curve close to a straight line or with a depression or convexity with a smaller curvature, and the depression can correspond to the antitragus; the third side 113 can be designed as a curve with a convexity with a smaller curvature, and the convexity can correspond to the antihelix. In one embodiment, the shape of the lower part of the panel 110 can be designed to be substantially similar to the shapes of the tragus, the antitragus, and the lower half of the antihelix (refer to Figure 7 ), the upper part of the panel 110 is substantially symmetric to the lower part but different. For example, the upper part of the panel 110 can be designed to be substantially similar to the shape of the corresponding part of the antihelix. For example, in the Figure 8 shown embodiment, when the user wears the customized wireless earphone 10, from the outside, most of the customized wireless earphone 10 is located in the user's cymba conchae, and a small part is located in the user's cavum conchae. Therefore, the first side 111 can be set to have three convexities in the middle and at both ends, and there are two depressions between the three convexities, but the curvatures of the convexities and depressions are smaller. The second side 112 is close to a straight line or has a depression with a smaller curvature. The third side 113 can be a curve similar to the contour of the antihelix, or can be other curve shapes.

[0055] Figure 5 is a schematic diagram of the panel 110 according to an embodiment of the present invention. As Figure 5 shown, the first angle α is the angle formed by the second section 116 and the first section 115, the first side 111, or the first direction y. Figure 5 Two sides of the first angle α are marked with two dashed lines in the figure. When measuring the first angle α, one side can be the line where the whole of the second section 116 is located, and the other side can be the line where the whole of the first section 115 is located, the line where the whole of the first side 111 is located, or the first direction y. The line where the whole of the first section 115 is located can be, for example, the line where the connection between the centers of the two ends of the first section 115 is located, or the line such that the first section 115 has the same length or area on both sides of it. The line where the whole of the second section 116 is located is similar to that of the first section 115, and its description is omitted here.

[0056] The second angle β is the angle formed by the third side 113 and the first section 115, the first side 111, or the first direction y. In Figure 5 the figure, two sides of the second angle β are marked with two dashed lines. When measuring the second angle β, one side can be the line where the whole of the third side 113 is located, and the other side can be the line where the whole of the first section 115 is located, the line where the whole of the first side 111 is located, or the first direction y. The line where the whole of the third side 113 is located can be the line where the relatively straight part in the middle of the third side 113 is located (for example, the middle half of the third side 113 or the upper one-third). In the case where the third side 113 is entirely an arc curve, the tangent direction at the upper one-third of the third side 113 can be taken as the line where the whole of the third side 113 is located.

[0057] In one embodiment, the second angle β can be greater than the first angle α. This is, for example, because the angle α is set smaller in consideration of the relatively small angle between the tragus and the antitragus. In other words, the second angle β being greater than the first angle α can mean that the opening at the junction of the third side 113 and the first side 111 is wider, while the opening at the junction of the second side 112 and the first side 111 is narrower, or the junction of the third side 113 and the second side 112 is closer to the upper side of the first side 111 in the first direction y. When the user wears the customized wireless earphone 10, the third side 113 is less restricted by the ear structure relative to the second side 112. Therefore, various designs can be adopted, such as being symmetric with the second side 112, or other designs can be used. In Figure 5In an embodiment, the second angle β is designed to be greater than the first angle α. The area of the panel 110 can be appropriately increased to better accommodate various components, and it can be more similar to the shape of the corresponding part of the customized housing 500 of the customized wireless earphone 10 to improve the ease of installation of the panel 110 and the customized housing 500. At the same time, it can also improve the fit of the panel 110 to the user's ear, thereby improving the wearing comfort, stability and noise reduction effect of the customized wireless earphone 10. In another embodiment, also for improving the ease of installation of the panel 110 and the customized housing 500, the shapes of the first side 111 and the second side 112 can also be designed to be similar to the shape of the corresponding part of the customized housing 500. When the sides of the panel 110 are similar to the corresponding parts of the customized housing 500 (such as the upper opening of the inner cavity 501, that is, the part of the customized housing 500 connected to the panel 110), the panel 110 and the customized housing 500 can be easily installed together by means of snap-fastening, adhesion, etc.

[0058] Although Figure 4 and Figure 5 do not clearly mark the two endpoints of the first side 111, the second side 112 and the third side 113, this can be set according to the actual situation. For example, it can be the part other than the rounded corners or arc segments used to connect two sides. The rounded corners or arc segments can correspond to a certain degree (such as 30 - 70 degrees).

[0059] In addition, in Figure 4 and Figure 5 the edge of the panel 110 is shown as a double solid line because the panel 110 has a certain thickness and in this embodiment the panel edge is formed as a ramp that is narrower at the top and wider at the bottom. Here, "top" refers to the side of the panel facing the outside of the ear when the user wears the customized wireless earphone 10, that is Figure 1 and Figure 2 the upper side shown in; here, "bottom" refers to the other side opposite to the "top". Of course, in other embodiments of the present invention, the edge of the panel 110 can also adopt a right-angle edge or a rounded transition edge, and the present invention does not limit this.

[0060] In addition to designing the shape of the panel 110, in the present invention, based on the size data obtained from taking ear molds of a large number of users, the size of the panel 110 is also designed to improve the wearing comfort, stability and noise reduction effect of the earphone, and to enable the components of the panel assembly to work properly while maintaining a high adaptation rate of the panel assembly.

[0061] Figure 6It is a schematic diagram of the panel 110 according to an embodiment of the present invention. In one embodiment, the length L of the panel 110 is 22.4 to 28.2 mm, and the width W is 14.3 to 20.3 mm. Herein, the length L of the panel 110 is the dimension of the panel 110 in the first direction y, and the width W of the panel 110 is the dimension of the panel 110 in the second direction x. The second direction x is the direction perpendicular to the first direction y on the panel 110. The length and width of the panel 110 can be obtained, for example, by using two parallel lines and measuring in the directions substantially perpendicular to the first direction y and the second direction x respectively. For example, as Figure 6 shown, place the panel 110 within two parallel lines DL1 and DL2 in the direction substantially perpendicular to the first direction y (or, in the second direction x) and make the panel 110 contact the two parallel lines. At this time, the distance between the two parallel lines DL1 and DL2 is the length L of the panel 110. Similarly, place the panel 110 between two parallel lines DL3 and DL4 in the direction substantially perpendicular to the second direction x (or, in the first direction y), and the distance between the two parallel lines DL3 and DL4 is the width W of the panel 110. Based on the size data obtained from taking ear molds of a large number of users, when the length L of the panel 110 is 22.4 to 28.2 mm and the width W is 14.3 to 20.3 mm, the fitting rate of the panel assembly 100 is over 70%. In this case, the panel assembly 100 can fit most customized housings 500 and most users, and the production cost of the earphone is reduced and the production efficiency is improved. When the panel 110 is within this size range, through appropriate arrangement, each component of the panel assembly 100 can work properly. If the size of the panel 110 is too small, there may be a situation where it is impossible to arrange each component of the panel assembly 100 (for example, the panel 110 does not have enough space to carry each component) or some components cannot work properly. At the same time, the wearing comfort, stability, and sound insulation and noise reduction effects of the earphone will also be reduced.

[0062] In the present invention, the adaptation rate of the panel assembly 100 refers to the ratio of the number of users for whom the panel assembly 100 can be applied to the customized wireless earphones 10 manufactured for them to the total number of users counted for a certain number of users. Specifically, "adaptation" means that the panel assembly 100 is matched to the customized housing 500 and the user's ear. If the design of the shape or size of the panel 110 is inappropriate, the panel assembly 100 cannot be matched to the customized housing 500 for the user or the user's ear, and this situation is called non - adaptation. For example, if the shape of the panel 110 is completely different from the shape of the connecting end of the customized housing 500 (the side connected to the panel 110) (for example, the former is circular and the latter is a rounded triangle), complex special designs are required to assemble them together, and in this case, the panel assembly 100 can be considered non - adapted. If the size of the panel 110 is too large, there is a large difference in size between the panel assembly 100 and the customized housing 500 or the user's ear, making it difficult to match (i.e., non - adapted). Moreover, in many cases, the panel 110 is located outside the ear, and when it is large in size, it is heavy and exerts a greater pressure on the ear of the wearing user, thus reducing the wearing comfort. If the size of the panel 110 is too small, in addition to the non - adaptation due to the large difference in size from the customized housing 500, there may also be non - adaptation cases because the panel 110 does not have enough space to accommodate the components of the panel assembly 100 or the components may not work properly. For example, because the size of the panel 110 is too small, the size of the control device 130 also needs to be reduced, resulting in the inability to achieve control, or because the size of the panel 110 is too small and there is not enough area to operate the control device 130 through the panel 110, thus leading to the inability to achieve normal control of the customized wireless earphones 10. In this case, the control device 130 cannot work properly. Another example is that because the size of the panel 110 is too small, the antenna device 160 is too close to other metal components (such as the control device 130, the battery 150, the magnet 170, etc.) and cannot send and receive signals normally. Therefore, in the present invention, the size of the panel 110 needs to be appropriately designed and cannot be too large or too small.

[0063] In another embodiment, the length of the panel 110 is 23.9 - 26.1 mm, and the width is 15.0 - 17.2 mm. In this case, the adaptation rate of the panel assembly 100 is above 85%. For example, when the length of the panel 110 is 24.8 mm and the width is 15.9 mm, the adaptation rate of the panel assembly 100 is about 99%. The panel 110 can be formed by one - time molding with a mold, or can be formed by cutting a circular, square or other - shaped board, and the present invention does not limit this.

[0064] The calculation of the adaptation rate can adopt simple mathematical methods or any other statistical methods. If the adaptation rate of a single type of panel component is low, then during the production process of customized wireless headphones, it is necessary to prepare panel components of multiple specifications, including panels and various components of multiple shapes and sizes, which increases the production cost and reduces the production efficiency. By designing the shape and size of the panel 110, the customized wireless headphones 10 can fit well with the shape of the ear during wearing, reducing the pressure of the customized wireless headphones 10 on the ear, and improving the wearing comfort, stability, and noise reduction effect of the headphones. At the same time, by designing the shape and size of the panel 110, while maintaining a high adaptation rate of the panel component 100, the various components of the panel component 100 can work properly, so that the panel component 100 of the same specification can be mainly used during the production process, reducing the production cost of the headphones and improving the production efficiency.

[0065] Return reference Figure 2 , continue to describe the customized wireless headphones 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 an 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 is in this plane. For example, the parts above and below the panel 110 in this plane 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 the components, so that the panel 110 can easily form the panel component 100 and facilitate its installation 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 these one or more components, there may be problems such as being unable to install them into the customized housing 500 due to the protrusions of the components or causing component collisions that affect the electrical connectivity of the components.

[0066] As Figure 2As 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 arranging them in this way, each component can be better accommodated within the inner cavity 501 of the customized housing 500. This is particularly important for the customized wireless earphone 10. Different from non-customized earphones that can be provided with larger external rod parts or bean parts, the customized wireless earphone 10 has only a small protrusion in the direction perpendicular to the ear (i.e., in the direction substantially perpendicular to the panel 110 when the customized wireless earphone 10 is worn), such as 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 (i.e., in the direction parallel to the panel 110 when the customized wireless earphone 10 is worn). Therefore, the volume of the inner cavity 501 of the customized housing 500 is very small, and the positions and sequences of each component need to be fully designed to accommodate each component within the inner cavity 501.

[0067] Although in Figure 1 and Figure 2 the example shown, the panel 110 is shown as being directly mounted to the customized housing 500, those skilled in the art can understand that the customized wireless earphone 10 may further include a panel adapter portion through which the panel 110 is mounted to the customized housing 500. As described above, during the manufacturing process of the customized wireless earphone 10, in order to reduce production costs and improve production efficiency, a panel 110 that can improve the adaptation rate of the panel assembly 100 is preferably used. That is to say, a panel 110 of a certain specific size is used for different users. However, since the ear sizes of different users (e.g., the concha size) vary greatly, there is a problem that the panel 110 that is suitable for some users is too small for other users. In this case, by providing the panel adapter portion, the panel 110 can be better mounted to the customized housing 500. The panel adapter portion can be a separate component or integral with the customized housing 500. For example, for users with larger ear sizes, when manufacturing the customized housing 500, it can be designed to have the panel adapter portion to narrow the opening of the uppermost part of the inner cavity 501 of the customized housing 500, so as to match its size with that of the panel 110 for facilitating the mounting of the panel 110 and the housing 500 together.

[0068] As Figure 2As shown, in one embodiment, the control device 130 is a touch panel that can be controlled above the panel 110, and the shape can be roughly circular or elliptical, or other shapes can be used. The control device 130 (touch panel) is roughly circular or elliptical, which means that the shape of the overall outer contour of the control device 130 is circular or elliptical. There may be some through holes or depressions on the control device 130, but this does not affect the shape of the overall outer contour of the control device 130. Those skilled in the art can easily determine the approximate shape of the control device 130. By operating the touch panel instead of a mechanical knob or a mechanical switch, the user can control the customized wireless headset 10 by applying a small force, thereby reducing the pressure on the ear caused by the control when the user wears the headset. At the same time, since the touch panel has a long life and high stability, the failure rate of the control device 130 is also reduced. The touch panel can adopt a conventional resistive or capacitive touch panel, or other touch technologies, and the present invention is not limited to this.

[0069] The operation of the control device 130 can control the switch, working mode, noise reduction, volume adjustment, and start, pause, previous song, next song, fast forward, fast rewind, etc. of the customized wireless headset 10. The working mode of the customized wireless headset 10 can be, for example, Hi-Fi (high fidelity) music mode, call mode, transparent mode, etc. For example, in Hi-Fi music mode, the audio output mode is adjusted to a mode suitable for playing music and the maximum noise reduction is turned on, so that the user can get a good music experience; in call mode, the dialogue voice is enhanced and appropriate noise reduction is turned on, so that the user can make a clear voice or video call; in transparent mode, the external sound is transmitted to the ear and the noise reduction is not turned on, so that the user can perceive the external sound normally as if he is not wearing headphones, so that he can interact normally with the outside world or others. The noise reduction mode can include, for example, maximum noise reduction, appropriate noise reduction, and no noise reduction, etc., 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 content, and may also include other content, and the control content may be pre-set or customized by the user.

[0070] Although in Figure 2 In the embodiment, the control device 130 is shown to be controlled through the panel 110, but those skilled in the art will appreciate that the control device 130 may be arranged in the panel assembly 100 in other ways and may be controlled in other ways. For example, a groove may be provided on the panel 110 to expose the control device 130, so that the user can directly operate the control device 130.

[0071] In one embodiment, the charging device 140 is a charging pin or a metal coil that can charge the customized wireless earphone 10 from above the panel 110. In Figure 2 , the charging device 140 is shown as including a plurality of charging pins, which, for example, extend into the panel 110 through the manipulation device 130 and contact the metal contacts of the charger or the charging base through the openings of the panel 110 from above the panel to charge the customized wireless earphone 10. Although in Figure 2 , it is shown that the charging pins extend into the panel 110 through the through holes on the manipulation device 130, the charging pins can also pass through the manipulation device 130 in other ways, such as extending into the panel 110 through the recesses on the outer periphery of the manipulation device 130, extending into the panel 110 outside the outer contour of the manipulation device 130, etc. By forming through holes or recesses in the manipulation device 130 for the charging pins to pass through, the arrangement of the manipulation device 130 and the charging device 140 can be made more compact, reducing the space occupied by these components on the panel 110 and within the housing 500, so that the sizes of the panel assembly 100 and the customized in-ear wearable device 10 can be reduced while the manipulation device 130 and the charging device 140 can still work properly, improving the adaptability rate of the panel assembly 100 and the wearing comfort of the earphone.

[0072] The charging pins can protrude from the openings of the panel 110, that is, the upper ends of the charging pins can be higher than the upper surface of the panel 110, but the charging pins can also not protrude from the openings of the panel 110, that is, the upper ends of the charging pins can be slightly lower than the upper surface of the panel 110. In the latter case, the metal contacts of the charger or the charging base 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.

[0073] The number of charging pins can be two, corresponding to the positive and negative poles respectively, or other numbers, such as one charging pin for the positive pole and three charging pins for the negative pole. As Figure 2As shown, one charging pin of the positive electrode can be located in the middle, for example, corresponding to the center of the touchpad 130, the battery 150, or the magnet 170; three charging pins of the negative electrode can be evenly arranged 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, insufficient height, etc., 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 during charging. The charging pins can have a fixed height or have a certain elasticity, so as to better connect when contacting the contacts of the charger or charging base.

[0074] 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 segments, broken line segments, and curve segments when viewed from above the panel. Fig. 9 is a perspective view of the customized wireless earphone 10 according to an embodiment of the present invention. In this embodiment, the charging pin is an arc-shaped piece, and an arc-shaped opening allowing the charging pin to extend into is provided on the panel, which is shown as an arc segment with a certain thickness in Figure 7 By setting the radian and thickness, the connection reliability between the charging pin and the charger or charging base can be improved.

[0075] Return to reference Figure 2 , in one embodiment, a support plate can be provided to fix the charging pins. In other embodiments, other methods can also be used to fix the charging pins. In the case where there are more than one charging pin for the same electrode, these charging pins can be electrically connected through a conductive metal sheet or metal wire, and the metal sheet or metal wire can be fixed on the support plate in the same way, for example.

[0076] In one embodiment, the charging device 140 can be a metal coil that charges the battery 150 of the customized wireless earphone 10 through wireless charging methods such as electromagnetic induction. This metal coil can be formed of a material such as copper, for example, and can be provided below the panel 110. In the case where the charging device 140 is a metal coil, the charger or charging base cooperating with it is a wireless charging device capable of charging the customized wireless earphone 10 in a wireless charging manner.

[0077] The battery 150 provides the power required for the operation of the customized wireless earphone 10. It can use rechargeable batteries of specific specifications, such as the 1054-type (i.e., a rechargeable battery with a cross-sectional diameter of 10 mm and a height of 54 mm), or other specifications of rechargeable batteries. The battery 150 can be a lithium-ion battery or other types of batteries, and the present invention does not limit this.

[0078] The antenna device 160 is used to transmit and receive wireless signals for the customized wireless earphone 10, enabling the customized wireless earphone 10 to operate in a wireless manner. For example, the antenna device 160 can be provided below the panel 110 near the first side 111, 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 transmit and receive wireless signals. The antenna device 160 can 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.

[0079] The magnet 170 is used to stably suck the customized wireless earphone 10 to the charger or charging base when the customized wireless earphone 10 is charging, thereby improving the charging connection stability. In one embodiment, the magnet 170 can be a circular magnet. In this case, its center can coincide with the center of the touchpad 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 can also be used. For example, the customized wireless earphone 10 may not include the magnet 170, or two magnets with different polarities can be used. The shape of the magnet can be various shapes such as circular, oval, square, etc. When the customized wireless earphone 10 uses two magnets with different polarities, corresponding settings can be made on the charger or charging base, so that the customized wireless earphone 10 and the charger or charging base can be better abutted together.

[0080] The main board 120 is used to load and connect the main components of the customized wireless earphone 10. These components include the control device 130, the charging device 140, the battery 150, the antenna device 160, the sound pickup device 180, the speaker assembly 190, the wireless communication module 195, etc. These components can be directly or indirectly (such as through various fixing components or through other components) fixed to the main board 120 by means of bolts, welding, gluing, etc. 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 shown embodiment, the main board 120 is a rigid main board and can be provided between the magnet 170 and the battery 150. In the absence of the magnet 170, it can also be provided between the control device 130 and the battery 150 or between the support plate of the charging device 140 and the battery 150. In one embodiment, the customized wireless earphone 10 can use a flexible main board, and reference will be made to Fig.10Describe it in detail.

[0081] Return reference Figure 2 , in one embodiment, the sound pickup device 180 may include two sound pickup devices 181 and 182. According to the functions of the customized wireless headset 10, the sound pickup devices 181 and 182 may be used to pick up the same type of sound or different types of sounds, such as for picking up ambient sound and / or call sound respectively. By using two or more sound pickup devices to pick up sound, 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 may also be used, such as one, three or more. The sound pickup device 180 may be any type of sound pickup device suitable for a headset, such as a microphone like a microelectromechanical microphone.

[0082] The speaker assembly 190 may include a sound output device for outputting sound for the customized wireless headset 10. The sound output device may be a balanced armature speaker, or a dynamic driver 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 wireless headset 10, an opening is usually provided on the customized housing 500 of the customized wireless headset 10 to allow the sound to pass through. In one embodiment, the speaker assembly 190 may further 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.

[0083] The wireless communication module 195 may be provided on the main board 120 or at other positions, and is used to process the signals of the customized wireless headset 10 so that it can perform wireless communication. The wireless communication module 195 may be a Bluetooth module, or other types of wireless communication modules, as long as it can realize the wireless operation of the customized wireless headset 10. The wireless communication module 195 may be integrated into the central processing unit (CPU) of the customized wireless headset 10, or may be a separate module.

[0084] As described above, the customized housing 500 may be manufactured by taking an ear mold of the user's ear and then based on the taken ear mold. The manufacturing method may be 3D printing or other manufacturing methods. In one embodiment, the customized wireless headset 10 may further include a ventilation duct provided on the customized housing 500 for ventilation when the user wears the customized wireless headset 10. One end of the ventilation duct may be located at the protruding part of the customized wireless headset 10 extending into the external auditory canal, and the other end may 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 wireless headset 10 and reduce the discomfort caused by the increase in the internal pressure of the ear.

[0085] In one embodiment, the customized housing 500 may include a first protrusion 510 and a second protrusion 520. When the user wears the customized wireless earphone 10, the first protrusion 510 may be located in the user's external auditory canal or in the user's concha and external auditory canal, and the second protrusion 520 may be located in the user's cymba conchae. Referring to Figure 7 and the description in this specification, the positional relationship between each part of the customized wireless earphone 10 and the user's ear can be understood when the user wears the customized wireless earphone 10. The first protrusion 510 may include an opening, and the speaker assembly 190 is located inside the first protrusion 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. In one embodiment, when the user wears the customized wireless earphone 10, most of the projection of the panel 110 in the direction of the user's ear is located in the user's concha, and a small part is located in the user's cymba conchae.

[0086] In one embodiment, the customized housing 500 may be integrally formed, that is, formed at one time based on the user's ear mold. In another embodiment, the customized housing 500 may also be composed of multiple parts. For example, the customized housing 500 may include a core part and a customized adaptation part, where the core part is the same for all users or most users, and it can be assembled with the panel assembly 100, while the customized adaptation part is the part formed based on the user's ear mold. In the case where the customized housing 500 includes a core part and a customized adaptation part, since the components other than the customized adaptation part are the same for most users, the production efficiency can be improved.

[0087] Fig.10 is an exploded view of the customized wireless earphone 20 according to an embodiment of the present invention. As Fig.10 shown, the customized wireless earphone 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, Fig.10 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 are 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

[0088] As Fig.10 As shown, the main board 220 can be a foldable circuit board or a flexible circuit board, which can at least partially surround the battery 250. By adopting a foldable 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.

[0089] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting 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.
