Description

Technical Field

[0001] This application relates to the technical field of earphone devices, and particularly to an earphone charging case.

Background Art

[0002] TWS (True Wireless Stereo) earphones, also known as fully wireless stereo earphones, have the characteristics that the left and right earphones exist independently, the connecting wire is completely unnecessary, they can be directly connected via Bluetooth for use, and the left and right earphones can be separated for use. TWS earphones have advantages such as being easy to carry, wear, and charge, so they are increasingly favored by more people.

[0003] Currently, the conventional charging case for TWS earphones can only charge the TWS earphones. In the charging process, it is difficult for people to directly obtain some operating states of the earphones or the charging case from the charging case, and it is necessary to improve the convenience in use.

Summary of the Invention

[0004] Embodiments of this application provide an earphone charging case that can improve the convenience in use of the earphone charging case.

[0005] According to an embodiment of the present invention, an earphone charging case is provided, comprising: a case body including a bottom case and an intermediate case connected to the bottom case, wherein the intermediate case and the bottom case surround each other to form a mounting cavity, the intermediate case is provided with a housing groove for housing earphones, and the intermediate case has a first light-transmitting region; a case cover movably connected to the case body, which opens and closes relative to the case body and has a second light-transmitting region; and a display module installed in the mounting cavity or the intermediate case, the position of which corresponds to the first light-transmitting region, wherein when the case cover is closed relative to the case body, the position of the second light-transmitting region corresponds to the first light-transmitting region, and the display module is capable of displaying content to the outside by passing through the first and second light-transmitting regions.

[0006] The earphone charging case according to the embodiment of the present invention has a movably connected case cover and case body, making it easy for the user to open and close the earphone charging case to store and remove the earphones. In particular, a storage groove is provided to stabilize the earphones, preventing damage to the earphones inside the earphone charging case during transport.

[0007] An additional display module has been installed, meaning that the information display function has been enhanced. The display module can display information such as the specific power level, charging status, ambient noise level, and noise reduction level of the earphones, improving the user's understanding of the earphone device's status data and enriching the usability of the earphone charging case.

[0008] The design of the first and second light-transmitting regions allows users to view information on the display module without opening the case cover. This improves the user experience, allowing users to quickly access information displayed on the display module without having to frequently open and close the earphone charging case.

[0009] Furthermore, by embedding the display module within the mounting cavity and viewing it through the first light-transmitting region, the display module is not directly exposed to the outside, reducing wear due to abrasion or friction from the outside, effectively protecting the display module from external damage, and extending its service life.

[0012] The achievement of the objectives, functional features, and advantages of this application will be further explained with reference to the drawings in conjunction with the embodiments.

[0013] To further clarify the purpose, technical means, and advantages of this application, embodiments of this application will be described in more detail below with reference to the drawings.

[0014] In the following description, when drawings are mentioned, unless otherwise specified, the same numbers in different drawings indicate the same or similar elements. The embodiments described in the following exemplary embodiments are not representative of all embodiments consistent with the present application. On the contrary, they are merely examples of apparatus and methods consistent with some aspects of the present application, which are described in detail in the appended claims.

[0015] In this description, terms such as "first," "second," etc., are merely descriptive and should not be understood as indicating or suggesting relative importance. A person skilled in the art will be able to understand the specific meaning of the above terms in this description depending on the specific situation. Also, in this description, unless otherwise specified, "plural" means two or more. "And / or" describes the relationship between related objects and indicates that three types of relationships are possible. For example, A and / or B indicates three cases: A exists alone, A and B exist simultaneously, and B exists alone. The letter " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0016] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terms used in this specification are for the purpose of describing particular embodiments only and are not intended to limit this application. The term "and / or" used in this specification includes any and all combinations of one or more of the associated listed items.

[0017] Since the earphone cable is not required for wireless earphones, problems such as the earphone cable of wired earphones being easily tangled and difficult to use are solved. However, after using wireless earphones for a long time, it is necessary to charge them. Taking TWS earphones as an example, it is often necessary to place the corresponding charging case for charging.

[0018] In the related art, a TWS earphone charging case charges the earphones by an internal battery, a magnetic member is installed, and the earphones can be fixed at a specific position to ensure the stability and accuracy during charging. Some TWS earphone charging cases are further equipped with an LED indicator lamp for displaying the charging state and power information. For example, a TWS earphone charging case may have three LED lamps, and different flashing modes or colors indicate states such as sufficient power, charging, or low power.

[0019] However, although the LED indicator lamp provides basic charging state information, its display ability is limited, and usually it can only provide simple power or state indications. Since such a display method has some limitations, users cannot accurately grasp the remaining amount of the earphones or the charging case. That is, the conventional earphone charging case has a single function and cannot fully meet the needs of users.

[0020] To solve the above problem, referring to Figures 1 to 5, the present application provides an earphone charging case 100, in which case the earphone charging case 100 is generally circular or rectangular and includes a case body 10 and a case cover 20. The case body 10 is provided with a housing groove 12a for housing the earphones 200, housing and protecting the earphones 200, and may be made of plastic, having a certain strength and durability. The case cover 20 is movably connected to the case body 10, and by opening and closing the case body 10 (i.e., the earphone charging case 100 has an open state and a closed state), the case cover 20 protects the earphones 200 from dust and external abrasion when they are housed in the housing groove 12a, and may be made of a material similar to that of the case body 10.

[0021] In one installation configuration, the case cover 20 is slidably connected to the case body 10, allowing the user to slide open and close the case cover 20 with one hand. The sliding connection reduces noise caused by frequent operation. In another installation configuration, the case cover 20 is reversibly connected to the case body 10. The flip cover structure is usually automatically opened and closed by a spring or other mechanical device, and the user can complete the opening operation simply by lightly pressing the open button or operating the case cover 20, making it very convenient.

[0022] As shown in Figures 4 and 6, the earphone charging case 100 further includes a display module 30, which can provide an information display function and display information such as the specific power level, charging status, ambient noise level, and noise reduction level of the earphones 200, thereby improving the user's understanding of the status of the earphones 200 device and improving the convenience of the earphone charging case 100.

[0023] Furthermore, the display module 30 includes a display screen and a drive circuit electrically connected to the display screen. The display screen is the core part of the display module, and the drive circuit controls the pixels on the display screen to generate an image or text. The drive circuit drives the pixel points on the display screen by adjusting the voltage and current as needed.

[0024] To make it clear, there are two housing grooves 12a, and the two housing grooves 12a are installed opposite each other. The display module 30 is located between the two housing grooves 12a, and the central position of the display module 30 improves the visibility and readability of the information on the display module 30.

[0025] Furthermore, the housing groove 12a includes a top groove and a bottom groove that communicate with each other, the top groove housing the ear pad of the earphone, the bottom groove housing the ear rod of the earphone, and the display module 30 is located between the two bottom grooves.

[0026] As shown in Figures 4 and 7, the case body 10 includes a bottom case 11 and an intermediate case 12 connected to the bottom case 11. The bottom case 11 supports the bottom of the case body 10 and provides structural stability to the case body 10. The housing groove 12a is installed in the intermediate case 12, which supports the earphone 200 and ensures stable housing of the earphone 200 within the earphone charging case 100. The intermediate case 12 and the bottom case 11 surround each other to form a mounting cavity 10a, which houses the battery 50 and other electronic components.

[0027] In one installation configuration, the display module 30 may be installed within the mounting cavity 10a, thus avoiding direct exposure of the display module 30 to the outside, preventing direct damage to the display module 30 from accidental scraping or dropping, and reducing the impact on the display module 30 from dust, moisture, and other contaminants that may affect the performance of the display module 30. This effectively protects the display module 30 from external damage and extends its service life.

[0028] In an alternative installation configuration, the display module 30 may be installed in the intermediate case 12, which has a groove formed in it. The groove houses the display module 30, fixing its position and contributing to reducing vibration or displacement during transportation or use.

[0029] Continuing to refer to Figures 4 and 6, the intermediate case 12 is further provided with a first light-transmitting region 111, and the case cover 20 is provided with a second light-transmitting region 21. The second light-transmitting region 21 is positioned in a location corresponding to the first light-transmitting region 111. When the case cover 20 is closed relative to the case body 10, the display content of the display module 30 can pass through the first light-transmitting region 111 and the second light-transmitting region 21, allowing the user to view the content displayed on the display module 30 from outside the earphone charging case 100. When the case cover 20 is open relative to the case body 10, the portion of the intermediate case 12 having the first light-transmitting region 111 is exposed to the outside, allowing the display content of the display module 30 to directly pass through the first light-transmitting region 111, allowing the user to directly obtain the content displayed on the display module 30. Therefore, whether the case cover 20 is closed or open, the user can view the information displayed in the display module 30, eliminating the need to frequently open and close the earphone charging case 100, thus improving the user experience.

[0030] Furthermore, the intermediate case 12 may be a transparent intermediate case made of plastic or a transparent intermediate case made of resin, that is, the entire intermediate case 12 may be a first light-transmitting region 111, and the case cover 20 may be a transparent case cover made of plastic or a transparent case cover made of resin, that is, the entire case cover 20 may be a second light-transmitting region 21, the intermediate case 12 may be an intermediate case portion in which part is transparent, and the case cover 20 may be a case cover portion in which part is transparent, and when the case cover 20 is closed relative to the case body 10, at least a part of the transparent intermediate case portion and the transparent case cover portion are installed facing each other along the vertical direction, and the display module 30 is installed facing the transparent intermediate case 12 portion, so that when the case cover 20 is closed, the user can easily see the contents displayed on the display module 30 through the case cover 20 and the intermediate case 12.

[0031] To make it clear, the case cover 20 is an integrally molded structural member, and / or the intermediate case 12 is an integrally molded structural member. Integrally molded structural members can reduce the number of members in the assembly process. For example, by using the transparent case cover 20 as a base and forming a non-light-transmitting region by painting or other methods, and leaving a part of the light-transmitting region to form a second light-transmitting region 21, the number of connection points can be reduced, the overall integrity of the case cover 20 can be maintained, a seamless connection on the exterior can be achieved, and the smoothness of the exterior contour can be maintained.

[0032] In some embodiments of the present invention, the upper surface of the case cover 20 is a smooth arc surface, and the smooth surface reduces friction with other objects, provides the user with a better grip, and is also easier to wipe and clean, contributing to the maintenance of hygiene of the earphone charging case 100.

[0033] As shown in Figures 2, 3, and 6, in some embodiments of the present invention, the second light-transmitting region 21 is configured to allow unidirectional transmission of light rays from the inside to the outside. That is, when the case cover 20 is closed, the special design of the second light-transmitting region 21 allows unidirectional transmission of light rays from the inside to the outside, and when the display module 30 is lit, 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 case cover 20 from the outside and cannot see the unlit display module 30, thereby providing a clearer and less interference-free visual experience. The unidirectional transmission function of the second light-transmitting region 21 effectively prevents interference of external light rays with the display module 30.

[0034] Continuing to refer to Figures 2 and 6, in some embodiments of the present invention, when the case cover 20 is closed to the case body 10 and the display module 30 is turned off, the second light-transmitting region 21 is configured to appear to integrate with the other parts of the case cover 20, thereby making the second light-transmitting region 21 inconspicuous when it is not necessary to display content, integrating with the other parts of the case cover 20, and allowing the user to be unaffected by the second light-transmitting region 21 when the display module 30 is turned off, thereby improving the overall aesthetics of the earphone charging case 100 without compromising the overall appearance design of the earphone charging case 100.

[0035] The seamless integration also protects the user's privacy by preventing others from peering into the charging case through the second light-transmitting area 21. When the case cover 20 is closed for storage and the display module 30 is illuminated, the second light-transmitting area 21 is configured to display the contents of the display module 30. That is, when it is necessary to view the contents of the display module 30, the second light-transmitting area 21 can clearly display the information without affecting the user's ability to operate and view it.

[0036] For example, the side of the second light-transmitting region 21 facing the display module 30 has low reflectivity, allowing more light rays to pass through, so that the light rays emitted when the display module 30 displays can pass through the second light-transmitting region 21 and be seen from the outside by the user. The side of the second light-transmitting region 21 away from the display module 30 has high reflectivity, so that it can reflect light rays from the external environment, so that what the user sees is not the structure of the internal display module 30, but their own reflected image or a reflection of the surrounding environment. Furthermore, the second light-transmitting region 21 and the other parts of the case cover 20 other than the second light-transmitting region 21 become integrated, achieving a unified appearance.

[0037] In some embodiments of the present invention, a light-shielding film is provided on the surface of the case cover 20, covering at least the second light-transmitting region 21, and the light-shielding film is usually made of a special material having unidirectional light transmission, such a material is designed with minute holes or structures that allow light rays to pass in one direction and block passage in the opposite direction. The light rays emitted by the display module 30 are self-luminous and therefore have a certain brightness and directionality. The design of the light-shielding film allows these light rays to pass through and propagate in a predetermined direction. However, external light rays are usually random in direction, and the design of the light-shielding film reduces the transmission of these external light rays by absorption, scattering or internal reflection when the film receives them.

[0038] In some embodiments of the present invention, the light-shielding film covers the entire surface of the case cover 20, and when the display module 30 is turned off, the light-shielding film makes it impossible to distinguish the second light-transmitting region 21 from the rest of the case cover 20 in appearance, thus achieving visual integration. By covering the entire surface of the case cover 20 with the light-shielding film, consistency in appearance of the earphone charging case 100 can be ensured, there is no difference in color or texture, and the product appears more refined. The surface of the case cover 20 covered with the light-shielding film is easy to clean because dirt is less likely to adhere to the light-shielding film.

[0039] Referring to Figure 7, in some embodiments of the present application, the intermediate case 12 includes a main case 121 and a window section 122, and the main case 121 and the window section 122 may be installed separately, which makes the design of the intermediate case 12 more modular and easier to produce and maintain. The main case 121 constitutes the base member of the intermediate case 12, and the above-mentioned housing groove 12a is installed in the main case 121, and the window section 122 may be installed facing the display module 30 in the vertical direction in order to allow the user to view the display information in the display module 30. The window section 122 may be a transparent window made of polymethyl methacrylate (PMMA, acrylic) which has good transparency and strength, or the window section 122 may be a glass window section 122 which provides higher transparency and abrasion resistance. To make it clear, the main case 121 is a non-light-transmitting main case 121 that can shield the structure of the battery 50 and other electronic components installed inside the housing cavity, preventing the internal structure from being directly exposed to the eye, and maintaining the clean and uniform appearance of the earphone charging case 100 when the case cover 20 is open relative to the case body 10.

[0040] As shown in Figures 7 and 8, the main case 121 is provided with an opening 121a, and the window section 122 is connected to the main case 121, covering the opening 121a and forming a first light-transmitting area 111. The size and position of the opening 121a and the first light-transmitting area 111 can be adjusted as needed, and the user can intuitively view the information displayed on the display module 30 in the housing cavity through the first light-transmitting area 111.

[0041] The surface of the window section 122 is flush with the surface of the main case 121. This flush design makes the seam between the window section 122 and the main case 121 less noticeable, providing a smooth and continuous surface to the intermediate case 12, improving the aesthetics of the earphone charging case 100, and reducing friction and wear caused by irregularities in the intermediate case 12.

[0042] Continuing to refer to Figures 7 and 8, the display module 30 is further connected to the window section 122. When installing, the display module 30 is first connected to the window section 122, and then the window section 122 is drilled into the opening 121a and connected to the main case 121. This ensures that the display module 30 is installed so that it is precisely aligned with the first light-transmitting area 111, thus avoiding potential misalignment or inaccurate alignment problems that may occur during assembly. Furthermore, this assembly method reduces the adjustment process that would be required if the modules were assembled separately, because the position and alignment of the display module 30 are already determined when it is connected to the window section 122.

[0043] When the case cover 20 is installed to be slidably connected to the case body 10, the sliding direction may be set to align with the direction from the window portion 122 to the housing groove 12a, and the design consistency and coherence are maintained because the sliding direction coincides with the direction from the window portion 122 to the housing groove 12a.

[0044] As shown in Figures 8 to 10, in some embodiments of the present invention, the window portion 122 includes a cover plate 1221 and a mounting edge plate 1222 connected to the periphery of the cover plate 1221, wherein the cover plate 1221 covers the opening 121a and forms a first light-transmitting region 111, the cover plate 1221 allows light rays to pass through the area of ​​the display module 30 and protects the display module 30 from external damage, the mounting edge plate 1222 provides extra support to the cover plate 1221 and can ensure stability when the cover plate 1221 is mounted on the opening 121a, the cover plate 1221 and the mounting edge plate 1222 surround each other to form a mounting groove 122a, the display module 30 is installed in the mounting groove 122a and can be protected from displacement by external impacts.

[0045] In some embodiments of the present invention, the earphone charging case 100 further includes an adhesive member 60 (see Figure 6), and the display module 30 is firmly fixed to the window portion 122 by being adhesively fixed to the groove wall of the mounting groove 122a via the adhesive member 60, thereby reducing displacement or detachment due to vibration or shock. In other mounting configurations, the display module 30 and the window portion 122 may be connected by screwing or locking, and the present invention is not limited thereto.

[0046] As shown in Figures 8 and 9, in some embodiments of the present invention, the mounting edge plate 1222 includes a guide plate 1222a and a fixing plate 1222b, and the main case 121 is provided with a guide groove 121b that fits the guide plate 1222a, and the guide plate 1222a is slidably connected to the guide groove 121b, that is, when assembling the window section 122, the window section 122 is passed through the main case 121 from the side where the guide groove 121b is installed, and the guide groove 121b can guide the guide plate 1222a to slide smoothly into the opening 121a along a predetermined trajectory, eliminating the need for complex alignment or adjustment steps and increasing the assembly speed of the window section 122 and the main case 121.

[0047] Furthermore, the main case 121 is provided with a locking groove 121c that fits the fixing plate 1222b. The fixing plate 1222b engages with and connects to the locking groove 121c, and when the mounting edge plate 1222 slides to the appropriate position, the fixing plate 1222b can be fitted into the locking groove 121c, achieving a secure fit between the fixing plate 1222b and the locking groove 121c, thereby achieving a strong assembly effect between the window section 122 and the main case 121.

[0048] Furthermore, the guide plate 1222a has a guide surface which is inclined along the direction toward the opening 121a, providing a smooth guide path that allows the mounting edge plate 1222 to easily slide into and position within the opening 121a of the main case 121. The inclined guide surface reduces friction between the mounting edge plate 1222 and the main case 121. Additionally, the thickness of the guide plate 1222a gradually increases along the direction away from the opening 121a, contributing to a progressive fit with the guide groove 121b, providing better adaptability and tightness during the assembly process.

[0049] Continuing to refer to Figures 8 and 9, in some embodiments of the present application, position limiting walls 1222c are provided on the two opposing side walls of the guide plate 1222a and the fixing plate 1222b, and the cover plate 1221 and the two position limiting walls 1222c are arranged around the periphery to form a mounting groove 122a, the position limiting walls 1222c can limit the position of the display module 30 and prevent tilting or displacement of the display module 30, and the position limiting walls 1222c can provide extra protection to the display module 30 and reduce potential damage to the display module 30 during use.

[0050] In this invention, by fixing the display module 30 to the window portion 122, the display module 30 can be fixed to the window portion 122 outside the case body 10 during the assembly process of the earphone charging case 100. This process does not involve working in the narrow space inside the case body 10, resulting in higher assembly efficiency. Furthermore, it is important to emphasize that the technical means of this invention further improves assembly efficiency by configuring the display module 30 and the window portion 122 as a single overall module and then fixing it to the case body 10 in an engaging manner.

[0051] As shown in Figures 6 and 7, in order to further improve the usability of the earphone charging case 100, in some embodiments of the present invention, the bottom case 11 is provided with a mounting hole 11a that communicates with a mounting cavity 10a, and the earphone charging case 100 further includes a touch assembly 40 that enables touch operation, is housed in the mounting cavity 10a, is partially exposed to the mounting hole 11a, and is electrically connected to the display module 30, so that the earphone charging case 100 can be personalized according to the user's preferences through smart interaction.

[0052] The bottom case 11 includes a bottom wall and side walls. The bottom wall is installed opposite the intermediate case 12, and the side walls are connected so as to extend from the outer edge of the bottom wall to the outer edge of the intermediate case 12. The mounting holes 11a are formed in the side walls. In other words, the circumferential side wall portion of the bottom case 11 makes it easier for the user to operate it directly, improving usability.

[0053] In some embodiments of the present invention, a charging port is further provided on the side opposite to the mounting hole 11a of the side wall, contributing to a rational allocation of the internal space of the earphone charging case 100 and avoiding interference between electronic devices.

[0054] In this embodiment, a touch function is added to the earphone charging case 100, enabling quick and convenient control of the earphone charging case 100 and wireless earphones 200 based on the user's operation on the touch assembly 40. This not only improves the user experience but also expands the earphone charging case 100 beyond being limited to an auxiliary device that provides auxiliary functions to the earphones 200. For example, it enables personalized settings such as ambient noise level, noise reduction level, barometric pressure calibration, shooting, earphone locator, and spatial audio function adjustment.

[0055] As shown in Figure 11, in some embodiments of the present application, the touch assembly 40 includes a touch panel 41, at least two inductor electrodes 42, and a control board 43. The touch panel 41 is installed in a mounting hole 11a and can be exposed from the mounting hole 11a to provide a touch operation area to the user, through which the user can execute various control commands. At least two inductor electrodes 42 are installed to support multitouch and enable the user to perform more complex gesture operations. The at least two inductor electrodes 42 are housed in a mounting cavity 10a and are positioned facing the touch panel 41. The inductor electrodes 42 induce control signals transmitted when the user operates the touch panel 41, and when the user performs a touch operation on the touch panel 41, such as a touch slide, long press, or double-click, the inductor electrodes 42 can detect changes on the touch panel 41 and generate corresponding electrical signals. The control board 43 is housed in the mounting cavity 10a and is electrically connected to the at least two inductor electrodes 42. It receives the control signals induced by the inductor electrodes 42 and converts these control signals into specific control commands. The control board 43 can respond quickly to user touch operations and provide the user with immediate operational feedback.

[0056] By replacing conventional physical buttons with a touch panel 41, mechanical wear can be reduced, extending the lifespan of the earphone charging case 100.

[0057] As shown in Figures 6 and 11, in some embodiments of the present invention, the touch panel 41 is installed on the opposite side of the housing groove 12a of the window portion 122 and adjacent to the window portion 122. By installing the touch panel 41 and the display module 30 in adjacent positions, a centralized control and information display area can be formed, improving the efficiency of user interaction. Furthermore, the touch panel 41 is not installed in an adjacent area where the earphones 200 are placed, reducing the possibility of accidentally touching the control panel during the process of inserting or removing the earphones 200.

[0058] Exemplary, at least two guide electrodes 42 are bonded to the side of the touch panel 41 facing the mounting cavity 10a, and the bonding enables a stable connection between the guide electrodes 42 and the touch panel 41, preventing displacement or detachment due to vibration or shock. Furthermore, bonding, as one method of fixation, can simplify the assembly process between the guide electrodes 42 and the touch panel 41.

[0059] In some configurations, the control board 43 incorporates a microcontroller unit (MCU) core with digital signal processing (DSP) circuitry, enabling it to rapidly process complex algorithms, meet real-time signal processing needs, and provide faster response times. Furthermore, software algorithms enable complex touch actions such as left and right slides, single clicks, double clicks, and long presses.

[0060] In some installation configurations, the induction electrode 42 is a capacitive induction electrode 42, which supports multi-touch technology, allowing users to operate with multiple fingers simultaneously, resulting in a richer interaction experience. Furthermore, the capacitive induction electrode 42 consumes less power, contributing to an extended lifespan of the earphone charging case 100.

[0061] As shown in Figures 12 to 14, in some installation configurations, the induction electrodes 42 can be rhomboid, circular, or W-shaped. Certain shapes of induction electrodes 42 can limit the effective touch area of ​​the touch panel 41, ensuring that the user operates within the desired area. Different shapes of induction electrodes 42 can improve the identification of touch signals and reduce false touches and missed touches.

[0062] As shown in Figure 11, in some embodiments of the present invention, the touch assembly 40 further includes a flexible circuit board 44 having bendable properties. The flexible circuit board 44 is installed in a mounting cavity 10a, allowing for complex wiring within the compact mounting cavity 10a and improving the space utilization of the mounting cavity 10a. At least two induction electrodes 42 and the control board 43 are electrically connected by a flexible circuit, and the flexible circuit board 44 is easily integrated with various electronic components and facilitates the implementation of multi-touch.
