The term "and / or" used herein includes any and all combinations of one or more associated listed items.

[0033] Wireless earphones solve the problems of wired earphones, such as entanglement of earphone wires and inconvenience of use, by eliminating earphone wires. However, wireless earphones need to be charged after long-term use. For example, TWS earphones are usually equipped with corresponding charging boxes for charging.

[0034] In related technologies, TWS earphone charging boxes charge earphones through internal batteries and are provided with magnetic parts to fix earphones in a specific position to ensure stability and accuracy during charging. Some earphone charging boxes are also equipped with LED indicator lights to display charging status and power information. For example, a TWS earphone charging box may have three LED lights to represent states such as sufficient power, charging or low power through different flashing modes or colors.

[0035] However, although LED indicator lights provide basic charging status information, their display capabilities are limited and can usually only provide simple power or status indications. This display method has some limitations, making it difficult for users to accurately understand the remaining power of earphones or charging boxes. That is, the existing earphone charging box functions are relatively simple and cannot fully meet the needs of users.

[0036] To solve the above problems, please refer to Figures 1 to 5The earphone charging box 100 is provided in the application. In the embodiment of the application, the earphone charging box 100 is in a shape of a circle or a square, and the earphone charging box 100 comprises a box body 10 and a box cover 20. The box body 10 is provided with a containing groove 12a for accommodating the earphone 200, and the box body 10 is used for accommodating and protecting the earphone 200. The box body 10 can be made of plastic and has certain strength and durability. The box cover 20 is movably connected with the box body 10 and is used for closing and opening the box body 10 (that is, the earphone charging box 100 has an open state and a closed state), so that the earphone 200 is prevented from being contaminated by dust and being scratched by the outside when the earphone 200 is accommodated in the containing groove 12a. The box cover 20 can be made of the same material as the box body 10.

[0037] In one form of arrangement, the box cover 20 is slidably connected with the box body 10, and a user can open or close the box cover 20 by sliding with one hand. The sliding connection can reduce the noise that can be generated due to frequent operation. In another form of arrangement, the box cover 20 is reversibly connected with the box body 10. The flip cover structure is usually realized by a spring or other mechanical device to automatically open and close. A user only needs to press the opening button or operate the box cover 20 to complete the opening operation, which is very simple.

[0038] As shown in Figure 4 and Figure 6 , the earphone charging box 100 further comprises a display module 30. The display module 30 can provide information display function and can be used to display the specific power, charging state, environmental sound level and noise reduction level and other information of the earphone 200. The display module 30 can improve the user's understanding of the state of the earphone 200 and improve the convenience of the earphone charging box 100.

[0039] Further, the display module 30 comprises a display screen and a driving circuit electrically connected with the display screen. The display screen is the core part of the display module, and the driving circuit is responsible for controlling the pixels on the display screen to generate images or texts. The driving circuit can adjust the voltage and current as needed to drive the pixels on the display screen.

[0040] Understandably, the number of the containing grooves 12a is two, and the two containing grooves 12a are oppositely arranged. The display module 30 is located between the two containing grooves 12a, and the display module 30 located at the central position improves the visibility and readability of the information of the display module 30.

[0041] Further, the containing groove 12a comprises a top groove and a bottom groove connected with each other. The top groove is used for placing the ear cap of the earphone, and the bottom groove is used for accommodating the ear stem of the earphone. The display module 30 is located between the two bottom grooves.

[0042] As shown in Figure 4 and Figure 7As shown, the box body 10 includes a bottom shell 11 and a middle shell 12 connected with the bottom shell 11, the bottom shell 11 provides a bottom support for the box body 10, and provides stability of the structure of the box body 10. The above-mentioned accommodating groove 12a is arranged on the middle shell 12, and the middle shell 12 can provide support for the earphone 200 and ensure stable placement of the earphone 200 in the earphone charging box 100. The middle shell 12 and the bottom shell 11 form a mounting cavity 10a, and the accommodating cavity can be used to accommodate the battery 50 and other electronic components.

[0043] In one form of arrangement, the display module 30 can be arranged in the mounting cavity 10a, which can avoid direct exposure of the display module 30 to the outside, prevent direct damage to the display module 30 in case of accidental scratching or falling, and also reduce the influence of dust, moisture and other pollutants that may affect the performance of the display module 30 on the display module 30, effectively protect the display module 30 from external damage, and prolong the service life of the display module 30.

[0044] In another form of arrangement, the display module 30 can also be arranged on the middle shell 12, and the middle shell 12 is provided with a recess, and the display module 30 is accommodated in the recess, which helps to fix the position of the display module 30 and reduce vibration or displacement during transportation or use.

[0045] Please continue to refer to Figure 4 and Figure 6 , further, the middle shell 12 is provided with a first light-transmitting area 111, and the box cover 20 is provided with a second light-transmitting area 21, the position of the second light-transmitting area 21 corresponds to the position of the first light-transmitting area 111, in the state that the box cover 20 closes the box body 10, the display content of the display module 30 can be transmitted through the first light-transmitting area 111 and the second light-transmitting area 21, so that the user can see the content displayed by the display module 30 from the outside of the earphone charging box 100, in the state that the box cover 20 opens the box body 10, the part of the middle shell 12 with the first light-transmitting area 111 is exposed to the outside, so that the display content of the display module 30 can be directly transmitted through the first light-transmitting area 111, so that the user can directly obtain the content displayed by the display module 30. Therefore, whether in the case of closing or opening the box cover 20, the user can view the display information on the display module 30, which improves the user experience, and the earphone charging box 100 does not have to be frequently opened and closed.

[0046] It should be noted that the middle shell 12 can be a plastic transparent middle shell or a resin transparent middle shell, that is, the middle shell 12 is entirely the first light transmission area 111, and the box cover 20 can be a plastic transparent box cover or a resin transparent box cover, that is, the box cover 20 is entirely the second light transmission area 21; or part of the middle shell 12 can be a transparent middle shell part, and part of the box cover 20 can be a transparent box cover part, and in the state that the box cover 20 closes the box body 10, at least part of the transparent middle shell part is arranged opposite to the transparent box cover part in the up-down direction, and the display module 30 is arranged opposite to the transparent middle shell 12 part, so as to facilitate the user to see the content displayed by the display module 30 through the box cover 20 and the middle shell 12 in the case that the box cover 20 is closed.

[0047] Understandably, the box cover 20 is an integrally formed structural member, and / or the middle shell 12 is an integrally formed structural member, and the integrally formed structural member can reduce the number of components in the assembly process, for example, directly on the basis of the transparent box cover 20, the non-light transmission area is formed by painting and the like, and part of the light transmission area is reserved to form the second light transmission area 21, which can reduce the connection points, retain the integrity of the box cover 20, realize seamless connection in appearance and keep the smoothness of the appearance line.

[0048] In some embodiments of the present application, the upper surface of the box cover 20 is a smooth arc surface, which can reduce the scratching of other objects and provide a better holding feeling for the user; and it is also easier to wipe and clean, which helps to maintain the hygiene of the earphone charging box 100.

[0049] As shown in Figure 2 , Figure 3 and Figure 6 , in some embodiments of the present application, the second light transmission area 21 is arranged to allow the light to be transmitted in a single direction from inside to outside, that is, when the box cover 20 is closed, the special design of the second light transmission area 21 allows the light to be transmitted in a single direction from inside to outside, and when the display module 30 is bright, the user can see the display content on the display module 30. When the display module 30 is turned off, the user can only see the surface of the box cover 20 from the outside, and cannot see the turned-off display module 30, which provides a clearer and non-disturbing visual experience. The single-direction transmission function of the second light transmission area 21 effectively prevents the interference of external light on the display module 30.

[0050] Please continue to refer to Figure 2 and Figure 6In some embodiments of the present application, when the box cover 20 closes the box body 10 and the display module 30 is in a screen-off state, the second light-transmitting area 21 is configured to display an integrated effect with the other parts of the box cover 20 except the second light-transmitting area 21, so that the second light-transmitting area 21 does not appear conspicuous when there is no need to display content, and is integrated with the other parts of the box cover 20, so that the user will not be affected by the second light-transmitting area 21 when the display module 30 is in a screen-off state, and the overall appearance design of the earphone charging box 100 is not damaged, thereby enhancing the overall aesthetics of the earphone charging box 100.

[0051] The integrated effect display can also prevent others from peering into the inside of the charging box through the second light-transmitting area 21, thereby protecting the user's privacy. When the box cover 20 closes the accommodation and the display module 30 is in a screen-on state, the second light-transmitting area 21 is configured to display the content of the display module 30, that is, when it is necessary to view the content of the display module 30, the second light-transmitting area 21 can clearly display information, without affecting the user's operation and viewing.

[0052] For example, the side of the second light-transmitting area 21 facing the display module 30 has a low reflectivity, allowing more light to pass through, so that when the display module 30 displays, the light emitted by the display module 30 can pass through the second light-transmitting area 21 and be seen by the user from the outside. The side of the second light-transmitting area 21 away from the display module 30 has a high reflectivity, which can reflect the light of the external environment, so that the user sees his own reflection or the reflection of the surrounding environment, rather than the structure of the internal display module 30, thereby making the second light-transmitting area 21 integrated with the other parts of the box cover 20 except the second light-transmitting area 21, thereby realizing the integrated effect.

[0053] In some embodiments of the present application, the surface of the box cover 20 is provided with a light-shielding film, and the light-shielding film covers at least the second light-transmitting area 21. The light-shielding film is usually made of a special material with unidirectional light transmission. This material is designed with tiny holes or structures that allow light to pass in one direction, but block it in the opposite direction. Since the light emitted by the display module 30 is active and has a certain brightness and directionality. The design of the light-shielding film allows these light to pass through and propagate in a predetermined direction; while external light is usually random direction, the design of the light-shielding film allows it to reduce light penetration by absorbing, scattering or internal reflection when receiving these external light.

[0054] In some embodiments of the present application, the light shielding film covers the entire surface of the box cover 20. In the display module 30 off-screen state, the light shielding film makes the second light transmission area 21 indistinguishable from other parts of the box cover 20 in appearance, achieving a visual integration effect. Covering the entire surface of the box cover 20 with a light shielding film can ensure the appearance consistency of the earphone charging box 100, without color or texture differences, making the product look more delicate. The surface of the box cover 20 covered with the light shielding film is easier to clean because stains are not easily adhered to the light shielding film.

[0055] Please refer to Figure 7 In some embodiments of the present application, the middle shell 12 includes a main shell 121 and a window part 122. The main shell 121 and the window part 122 can be separately provided, which makes the design of the middle shell 12 more modular, facilitating production and maintenance. The main shell 121 constitutes the basic component of the middle shell 12, on which the above-mentioned accommodating groove 12a is provided. The window part 122 can be arranged opposite to the display module 30 in the up-down direction, allowing the user to see the display information on the display module 30. The window part 122 can be a polymethyl methacrylate (PMMA) transparent window, which has good transparency and strength; or the window part 122 can be a glass window part 122, which provides higher transparency and wear resistance. Understandably, the main shell 121 is a non-light-transmitting main shell 121, which can shield the battery 50 and other electronic components and structures arranged inside the accommodating cavity, avoiding direct exposure of the internal structure to the line of sight, and maintaining the neatness and unity of the appearance of the earphone charging box 100 in the state of the box cover 20 opening the box body 10.

[0056] As shown in Figure 7 and Figure 8 , and the main shell 121 is provided with an opening 121a. The window part 122 is connected with the main shell 121 and covers the above-mentioned opening 121a, and the window part 122 forms a first light transmission area 111. The size and position of the opening 121a and the first light transmission area 111 can be adjusted as needed. Through the first light transmission area 111, the user can directly see the information displayed on the display module 30 in the accommodating cavity.

[0057] Among them, the surface of the window part 122 is flush with the surface of the main shell 121. The flush design makes the joint between the window part 122 and the main shell 121 less obvious, providing a smooth and continuous surface for the middle shell 12, enhancing the aesthetics of the earphone charging box 100, and reducing scratches and wear caused by unevenness on the middle shell 12.

[0058] Please continue to refer to Figure 7 and Figure 8Further, the display module 30 is connected to the window portion 122. During installation, the display module 30 is connected to the window portion 122 first, and then the window portion 122 is arranged in the opening 121a and connected to the main housing 121. In this way, the display module 30 can be accurately aligned with the first light-transmitting area 111, and the misalignment or inaccurate alignment that may occur during assembly can be avoided. In addition, this assembly method can simplify the entire assembly process. Since the position and alignment of the display module 30 are determined when the display module 30 is connected to the window portion 122, the adjustment process in the separate assembly process is reduced.

[0059] When the box cover 20 is arranged in a sliding connection with the box body 10, the sliding direction can be arranged in a direction from the window portion 122 to the accommodating groove 12a. The sliding direction is consistent with the direction from the window portion 122 to the accommodating groove 12a, and the design coherence and consistency are maintained.

[0060] As shown in FIG. 1, Figures 8 to 10 In some embodiments of the present application, the window portion 122 includes a cover plate 1221 and a mounting side plate 1222 connected to the periphery of the cover plate 1221. The cover plate 1221 covers the opening 121a and forms the first light-transmitting area 111. The cover plate 1221 allows light to pass through the area of the display module 30 and protects the display module 30 from external damage. The mounting side plate 1222 can provide additional support for the cover plate 1221 and ensure the stability of the cover plate 1221 when the cover plate 1221 is arranged in the opening 121a. The cover plate 1221 and the mounting side plate 1222 form a mounting groove 122a. The display module 30 is arranged in the mounting groove 122a, and the display module 30 is protected from displacement caused by external impact.

[0061] In some embodiments of the present application, the earphone charging box 100 further includes an adhesive 60 (as shown in FIG. 1), Figure 6 The display module 30 is fixedly arranged on the window portion 122 by being adhered and fixed to the groove wall of the mounting groove 122a through the adhesive 60, so that the display module 30 is firmly fixed on the window portion 122 and displacement or falling caused by vibration or impact is reduced. In other forms of arrangement, the display module 30 and the window portion 122 can also be connected by screwing or clamping, which is not limited in the present application.

[0062] As shown in FIG. 1, Figure 8 and Figure 9As shown, in some embodiments of the present application, the mounting side plate 1222 comprises a guide plate 1222a and a fixing plate 1222b, the main shell 121 is provided with a guide groove 121b matched with the guide plate 1222a, and the guide plate 1222a is in sliding connection with the guide groove 121b, that is, when the window part 122 is assembled, the window part 122 is inserted from the side of the main shell 121 provided with the guide groove 121b, and the guide groove 121b can guide the guide plate 1222a to slide smoothly along a preset trajectory towards the opening 121a, without the need for complex alignment or adjustment steps, thereby speeding up the assembly of the window part 122 and the main shell 121.

[0063] Further, the main shell 121 is provided with a clamping groove 121c matched with the fixing plate 1222b, and the fixing plate 1222b is in clamping connection with the clamping groove 121c, when the mounting side plate 1222 slides to a suitable position, the fixing plate 1222b can be embedded in the clamping groove 121c, so as to realize the clamping connection between the fixing plate 1222b and the clamping groove 121c, thereby achieving the firm assembly effect between the window part 122 and the main shell 121.

[0064] Further, the guide plate 1222a has a guide surface inclined towards the opening 121a, which provides a smooth guide path, so that the mounting side plate 1222 can be more easily slid into and positioned at the opening 121a of the main shell 121, and the inclined guide surface reduces the scratching between the mounting side plate 1222 and the main shell 121, and the thickness of the guide plate 1222a gradually increases in the direction away from the opening 121a, which helps to realize the gradual cooperation with the guide groove 121b, thereby providing better adaptability and tightness during assembly.

[0065] Please continue to refer to Figure 8 and Figure 9 In some embodiments of the present application, the two opposite side walls of the guide plate 1222a and the fixing plate 1222b are each provided with a limiting wall 1222c, and the cover plate 1221 and the two limiting walls 1222c jointly form a mounting groove 122a, the limiting wall 1222c can limit the display module 30, prevent the display module 30 from tilting or deviating, and the limiting wall 1222c can provide additional protection for the display module 30, thereby reducing the potential damage to the display module 30 during use.

[0066] It is emphasized here that the application can fix the display module 30 on the window part 122 outside the box body 10 during the assembly process, which has the characteristics of higher assembly efficiency because it is not operated in the narrow space inside the box body 10. Moreover, the application can further improve the assembly efficiency by fixing the display module 30 and the window part 122 to the box body 10 through clamping after forming an integral module.

[0067] As shown in Figure 6 and Figure 7 To further improve the convenience of the earphone charging box 100, in some embodiments of the application, the bottom shell 11 is provided with a mounting hole 11a which communicates with the mounting cavity 10a. The earphone charging box 100 further comprises a touch assembly 40 for realizing touch operation. The touch assembly 40 is accommodated in the mounting cavity 10a and partially exposed in the mounting hole 11a. The touch assembly 40 is electrically connected with the display module 30, so that the earphone charging box 100 can realize personalized settings according to user's preferences through intelligent interaction.

[0068] It should be noted that the bottom shell 11 comprises a bottom wall and a side wall. The bottom wall is arranged opposite to the middle shell 12, and the side wall extends from the outer edge of the bottom wall to the outer edge of the middle shell 12. The mounting hole 11a is formed on the side wall, i.e. the circumferential side wall of the bottom shell 11, which is more convenient for users to operate directly and improves the convenience of use.

[0069] In some embodiments of the application, the side wall opposite to the mounting hole 11a is further provided with a charging interface, which is beneficial to reasonably allocate the internal space of the earphone charging box 100 and avoid interference between electronic devices.

[0070] The embodiment adds a touch function to the earphone charging box 100. Not only can it realize quick and convenient control of the earphone charging box 100 and the wireless earphone 200 according to user's operation on the touch assembly 40, but also improve user experience. Moreover, it can make the earphone charging box 100 not limited to an auxiliary device for providing auxiliary functions for the earphone 200, and can realize personalized settings such as environmental sound level, noise reduction level, air pressure calibration, photographing, finding the earphone 200, and spatial audio function adjustment.

[0071] As shown in Figure 11As shown, in some embodiments of the present application, the touch assembly 40 comprises a touch panel 41, at least two sensing electrodes 42 and a control board 43. The touch panel 41 is arranged in the mounting hole 11a, and the touch panel 41 can be exposed in the mounting hole 11a to provide a touch operation area for the user, and the user can perform various control commands through the touch panel 41. At least two sensing electrodes 42 are arranged to support multi-point touch and allow the user to perform more complex gesture operations. The at least two sensing electrodes 42 are accommodated in the mounting cavity 10a and arranged opposite to the touch panel 41, and the sensing electrodes 42 are used to sense the control signals transmitted by the user when operating the touch panel 41, and when the user performs touch operations on the touch panel 41, such as touch sliding, long pressing or double clicking, the sensing electrodes 42 can detect the changes on the touch panel 41 and generate corresponding electrical signals. The control board 43 is accommodated in the mounting cavity 10a and electrically connected with the at least two sensing electrodes 42, and the control board 43 is used to receive the control signals sensed by the sensing electrodes 42 and convert these control signals into specific control instructions. The control board 43 can quickly respond to the user's touch operation and provide immediate operation feedback to the user.

[0072] By arranging the touch panel 41 to replace the traditional physical keys, mechanical wear and tear can also be reduced, and the service life of the earphone charging box 100 can be prolonged.

[0073] As shown in Figure 6 and Figure 11 As shown, in some embodiments of the present application, the touch panel 41 is arranged on the side of the window portion 122 opposite to the accommodation groove 12a and adjacent to the window portion 122. By arranging the touch panel 41 and the display module 30 adjacent to each other, a centralized control and information display area can be formed, the efficiency of user interaction can be improved, and the touch panel 41 is not arranged in the adjacent area where the earphone 200 is placed, thereby reducing the possibility of mistakenly touching the control panel during the process of taking and placing the earphone 200.

[0074] For example, the at least two sensing electrodes 42 are bonded to the side of the touch panel 41 facing the mounting cavity 10a. Bonding can provide stable connection between the sensing electrodes 42 and the touch panel 41 and prevent displacement or falling caused by vibration or impact. Moreover, bonding as a fixing method can simplify the assembly process of the sensing electrodes 42 and the touch panel 41.

[0075] In some forms of arrangement, the control board 43 is a microcontroller unit (MCU) kernel carrying a digital signal processing (DSP) circuit, which can quickly process complex algorithms, meet the real-time signal processing requirements, and provide faster response. Through software algorithms, complex touch actions such as left and right sliding, single clicking, double clicking and long pressing can be realized.

[0076] In some forms of implementation, the sensing electrode 42 is a capacitive sensing electrode 42, which supports multi-touch technology, allows the user to operate through multiple fingers at the same time, realizes a more rich interactive experience, and has low power consumption, which helps to prolong the service life of the earphone charging box 100.

[0077] As shown in Figures 12 to 14 In some forms of implementation, the sensing electrode 42 is in the shape of a diamond, a circle or a W shape. The sensing electrode 42 in a specific shape can define an effective touch area on the touch panel 41, ensuring that the user operates within the expected area. Sensing electrodes 42 in different shapes can improve the recognition of touch signals and reduce false touches and missed touches.

[0078] As shown in Figure 11 In some embodiments of the present application, the touch assembly 40 further includes a flexible circuit board 44, which has bendable properties. The flexible circuit board 44 is arranged in the mounting cavity 10a and can perform complex wiring in the compact mounting cavity 10a, improving the space utilization of the mounting cavity 10a. The at least two sensing electrodes 42 and the control board 43 are electrically connected through the flexible circuit board 44, which is easy to integrate with various electronic components and facilitate the realization of multi-touch.
