Description

Technical Field

[0001] This invention belongs to the field of headphones, and more specifically, relates to a wireless headphone with a battery level display and its wireless headphone case. Background Technology

[0002] With the development of Bluetooth technology, wireless headphones have become increasingly popular in the consumer electronics market due to their advantage of being free from the constraints of cables, and are widely used in scenarios such as music listening, calls, and gaming. Among them, ear-hook headphones are a type of headphone that is fixed to the ear through an ear hook structure. Their core feature is that they rely on the support and fit of the ear hook to maintain wearing stability, avoiding the problem of falling out that may occur with traditional in-ear or over-ear headphones. This design was first commonly seen in sports scenarios, and now it has extended to daily commutes and office work. However, when existing ear-hook headphones are charged in the earphone housing of the charging case, only the earphone body can be magnetically fixed and positioned, but the ear hook cannot be fixed and positioned. This can easily cause the ear hook to shift position, leading to poor charging contact.

[0003] Chinese patent CN221807170U discloses an open-back earhook headphone and its charging case that are securely fixed for charging. The device has an earhook magnet installed inside the end of the earhook away from the headphone body. Therefore, when the open-back earhook headphone is charged in the charging case, both the headphone body and the earhook can be magnetically fixed by the charging case, preventing the earhook from shifting position and ensuring stable and reliable charging. However, the position and shape of the earhook in this device are fixed and cannot be adjusted according to the shape of the user's ear, thus reducing the device's versatility.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a wireless earphone with a power display and its wireless earphone case, thereby solving the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0008] An adjusting rod is fixedly installed on the connecting rod and movably mounted on the hanging lug rod. An adjusting groove that allows the adjusting rod to move is passed through the hanging lug rod. Multiple limiting grooves are recessed along the length of the adjusting rod. An adjusting component that limits the limiting grooves is provided on the hanging lug rod.

[0009] Optionally, the adjustment component includes:

[0010] A movable plate is movably disposed within the hanging rod, and the hanging rod is provided with a movable groove for the movable plate to move within it;

[0011] A limiting block is fixedly installed on the movable plate relative to the limiting groove. A movable rod is fixedly installed on one end of the movable plate away from the limiting block. A drive assembly for driving the movable rod to move is provided on the hanging rod.

[0012] Optionally, the lug rod is provided with a mounting slot for mounting the drive assembly, the drive assembly including:

[0013] A drive plate is fixedly installed on one end of the movable rod away from the movable plate. A first rotating shaft is movably connected through the drive plate, and a drive groove is provided through the drive plate to allow the first rotating shaft to move.

[0014] The second rotating shaft is rotatably disposed in the mounting groove. A rotating plate with its other end rotatably connected to the first rotating shaft is fixedly mounted on the second rotating shaft. The lug rod is provided with a worm gear mechanism that drives the second rotating shaft to rotate.

[0015] Optionally, the movable groove is provided with a spring that abuts against the movable plate, and the spring is sleeved on the movable rod.

[0016] Optionally, the earplug includes a mounting tube fixedly connected to the headphone body and an end cap detachably connected to the mounting tube. The inner wall of the retaining ring is fixedly mounted with a plurality of first retaining blocks along its circumference, and the mounting tube is provided with a plurality of first retaining slots that can engage with the first retaining blocks.

[0017] Optionally, a connecting plate and a second slot are fixedly installed on the end cap, and the mounting cylinder is provided with a connecting groove and a second locking block that can engage with the connecting plate and the second slot.

[0018] Optionally, multiple airbags are fixedly installed at intervals along the length of the inner side of the hanging rod, and multiple valves are provided on the hanging rod that are respectively connected to the multiple airbags.

[0019] Optionally, a display screen and indicator lights are fixedly installed on the earphone body.

[0020] This embodiment also provides a wireless earphone case, including a case body, for storing the wireless earphones with battery level display described in any of the above embodiments.

[0021] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0022] 1. By setting up adjustment components, a retaining ring, and an adjustment rod, the retaining ring is rotated at the connection between the earbud and the headphone body, allowing the ear hook to rotate relative to the headphone body to achieve multi-angle adjustment. At the same time, the setting of adjustment components, adjustment rod, and limiting groove allows users to precisely adjust the size of the ear hook according to their own ear size, improving the versatility of the device and enhancing the user experience.

[0023] 2. By setting a first locking block and a first locking slot, the ear hook can adjust its angle as the locking ring rotates, adapting to the tilt direction of different users' auricles (such as the ear hook can bend forward or backward), avoiding the ear pressure caused by the fixed angle of traditional fixed ear hooks.

[0024] 3. By incorporating an air bladder, the air bladder can fill the irregular gaps between the ear hook and the auricle (such as the depression between the helix and antihelix) after inflation, changing the ear hook from the traditional "single-point contact" to "surface contact". It uses flexible air pressure to adapt to the auricle shape of different users, solving the pain point of the traditional "one-size-fits-all" ear hook. It is especially suitable for sports, long-term wear and scenarios with high personalization needs.

[0041] The invention will now be described in further detail with reference to the accompanying drawings.

[0042] Please see Figure 1-10As shown, this embodiment provides a wireless earphone with a battery level display, including an earphone body 1 and an earbud 3, an ear hook 4, which includes an ear hook rod 41, a connecting rod 42 and a retaining ring 43. The retaining ring 43 is fixedly connected to the connecting rod 42. The retaining ring 43 has an arc-shaped structure and is engaged and rotatably disposed at the connection between the earbud 3 and the earphone body 1. An adjusting rod 10 is fixedly installed on the connecting rod 42 and is movably disposed on the ear hook rod 41. An adjusting groove 11 that allows the adjusting rod 10 to move is passed through the ear hook rod 41. The adjusting rod 10 has multiple limiting grooves 13 recessed along its length direction. The ear hook rod 41 is provided with an adjusting component 9 that limits the limiting grooves 13.

[0043] Specifically, in this embodiment, when the user receives the earphones, the ear hook 41, connecting rod 42, retaining ring 43, and adjusting rod 10 are in their default assembly state. The adjusting rod 10 is located in the adjusting groove 11 of the ear hook 41. The adjusting component 9 positions the limiting groove 13 on the adjusting rod 10. When the user needs to wear the earphones, they hold the ear hook 41 and connecting rod 42 according to their own ear shape and adjust the ear hook 4. Since the retaining ring 43 is an arc-shaped structure and is locked and rotated at the connection between the earbud 3 and the earphone body 1, the user can rotate the retaining ring 43 to adjust the angle between the ear hook 4 and the earphone body 1 to adapt to different wearing habits and ear fit requirements. At the same time, the adjusting component 9 releases the limiting groove 13. Then, pull or push the connecting rod 42 according to the actual situation, so that the adjusting rod 10 slides in the adjusting groove 11 of the ear hook rod 41, changing the relative position of the ear hook rod 41 and the connecting rod 42, thereby adjusting the overall shape and size of the ear hook 4. After the adjusting rod 10 moves to the designated position, it is automatically embedded in the limiting groove 13 by the adjusting component 9 to achieve positioning. The retaining ring 43 is rotated and set at the connection between the earbud 3 and the headphone body 1, so that the ear hook 4 can rotate relative to the headphone body 1 to achieve multi-angle adjustment. At the same time, the setting of the adjusting component 9, the adjusting rod 10 and the limiting groove 13 allows the user to accurately adjust the size of the ear hook 4 according to their own ear size, improving the versatility of the device and enhancing the user experience.

[0044] It should be noted that, in this embodiment, the internal structure and working principle of the earphone body 1 and the earplug 3 are existing technologies and will not be described here. Secondly, the ear hook 4 typically includes a metal frame (commonly nickel-titanium shape memory alloy (such as 0.7mm diameter ultra-soft metal wire), titanium alloy or aluminum alloy, which has shape memory and high resilience characteristics and can automatically adjust the bending angle according to the ear shape), an outer layer material (generally using liquid silicone or skin-friendly silicone to wrap the metal frame, which is soft to the touch and has anti-slip properties, with a coverage rate of over 81.5%), and auxiliary materials (some products use polycarbonate (PC) or polyurethane (PU) plastics for specific parts to enhance wear resistance or reduce weight). Furthermore, a limiting plate 14 is fixedly installed on the adjustment rod 10, and the limiting plate 14 is movably disposed in the adjustment groove 11.

[0045] In this embodiment, as Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 7As shown, the adjusting component 9 includes a movable plate 92, which is movably disposed within the hanging rod 41. The hanging rod 41 has a movable groove 95 for the movable plate 92 to move, and a limiting block 91, which is fixedly installed on the movable plate 92 relative to the limiting groove 13. A movable rod 93 is fixedly installed on the end of the movable plate 92 away from the limiting block 91. The hanging rod 41 has a driving component 94 for driving the movable rod 93 to move, and a mounting groove 15 for mounting the driving component 94. The driving component 94 includes a driving plate 941, which is fixedly installed on the end of the movable rod 93 away from the movable plate 92. A first rotating shaft 943 is movably connected through and movably connected to the driving plate 941. A passage for the first rotating shaft 943 is movably connected through the driving plate 941. The movable drive groove 942 and the second rotating shaft 945 are rotatably disposed within the mounting groove 15. A rotating plate 944, whose other end is rotatably connected to the first rotating shaft 943, is fixedly mounted on the second rotating shaft 945. A worm gear mechanism 946 for driving the second rotating shaft 945 to rotate is provided on the lug rod 41. A spring 16 abutting against the movable plate 92 is provided in the movable groove 95. The spring 16 is sleeved on the movable rod 93. Specifically, in this embodiment, the worm gear mechanism 946 includes a worm wheel and a worm. The worm wheel is sleeved and fixedly mounted on the second rotating shaft 945. The worm meshes with the worm wheel and is rotatably disposed within the mounting groove 15. Its control end extends to the outside of the lug rod 41 and is fixedly mounted with a handle 22. In the initial state, the movable... Under the elastic force of the spring 16, the movable plate 92 causes the limiting block 91 to embed into a limiting groove 13 of the adjusting rod 10. At this time, the ear hook 4 is in a fixed state, and the adjusting rod 10 cannot slide freely. When adjusting the size of the ear hook 4, the user drives the worm gear to rotate by rotating the handle 22 with external force. The worm gear drives the worm wheel to rotate, which in turn drives the second rotating shaft 945 to rotate. When the second rotating shaft 945 rotates, it drives the rotating plate 944 to rotate. Its other end pushes the first rotating shaft 943 to slide in the driving groove 942, forcing the driving plate 941 to move away from the movable plate 92. The movable rod 93 drives the movable plate 92 to move away from the adjusting rod 10. At the same time as compressing the spring 16, the limiting block 91 moves out of the limiting groove of the adjusting rod 10. When the ear hook 4 is disengaged from the ear hook 41, the adjusting rod 10 is unlocked and can slide freely in the adjusting groove 11. The user can pull or push the connecting rod 42 according to the size of the ear, causing the adjusting rod 10 to slide in the adjusting groove 11 of the ear hook 41, changing the relative length between the ear hook 41 and the connecting rod 42 until the ear hook 4 fits the ear. After the position is adjusted, the user drives the worm gear to rotate by the handle 22 in the opposite direction. The spring 16 pushes the movable plate 92 to reset, causing the limit block 91 to re-embed into a certain limit groove 13 of the adjusting rod 10, completing the locking. The spring 16 facilitates the reset of the movable plate 92. The setting of the adjusting component 9 achieves precise locking and stable adjustment of the adjusting rod 10, and the overall operation steps are simple and highly stable.

[0046] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the earplug 3 includes a mounting cylinder 31 fixedly connected to the headphone body 1 and an end cap 32 detachably connected to the mounting cylinder 31. Multiple first locking blocks 5 are fixedly installed on the inner wall of the retaining ring 43 along its circumferential direction. The mounting cylinder 31 is provided with multiple first locking slots 6 that can engage with the first locking blocks 5. Specifically, in this embodiment, the retaining ring 43 is fixedly engaged with the first locking blocks 5 and the first locking slots 6 in a circumferential manner, but the retaining ring 43 is allowed to rotate slightly on the mounting cylinder 31. Since the retaining ring 43 is fixedly connected to the connecting rod 42 of the ear hook 4, the ear hook 4 can adjust its angle as the retaining ring 43 rotates to adapt to the tilt direction of different users' auricles (such as the ear hook 4 can be bent forward or backward), avoiding the ear pressure caused by the fixed angle of the traditional fixed ear hook 4.

[0047] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 8 and Figure 9 As shown, a connecting plate 19 and a second slot 20 are fixedly installed on the end cap 32. The mounting cylinder 31 is provided with a connecting groove 17 and a second locking block 18 that can engage with the connecting plate 19 and the second slot 20. Specifically, the arrangement of the second locking block 18, the second slot 20, the connecting block and the connecting groove 17 facilitates the detachable connection between the mounting cylinder 31 and the end cap 32, and facilitates the cleaning of the grid on the end cap 32.

[0048] In this embodiment, as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, multiple airbags 8 are fixedly installed at intervals along the length of the inner side of the ear hook 41. The ear hook 41 is equipped with multiple valves 7, each communicating with one of the airbags 8. Specifically, the user injects air into the airbags 8 by pressing or rotating the valves 7 (such as one-way valves) on the ear hook 41. Since the airbags 8 are fixed to the inner side of the ear hook 41 (the side closest to the ear), the airbags 8 expand after inflation, increasing the fit between the ear hook 4 and the ear. When deflating, the air in the airbags 8 is released by opening the valves 7. When the bladder 8 contracts, the pressure between the inner side of the ear hook 41 and the auricle decreases, and the ear hook 4 can return to its initial state or be adjusted to a smaller clamping force. After the bladder 8 expands, it can fill the irregular gap between the ear hook 41 and the auricle (such as the depression between the helix and the antihelix), so that the ear hook 4 changes from the traditional "single point contact" to "surface contact". It uses flexible air pressure to adapt to the auricle shape of different users, solves the pain point of the traditional ear hook 4's "one-size-fits-all" wearing, and is especially suitable for sports, long-term wear and high personalized needs.

[0049] In this embodiment, as shown in the figure, a display screen 2 and an indicator light 21 are fixedly installed on the earphone body 1. Specifically, the power detection component (such as a battery power monitoring chip) built into the earphone body 1 monitors the battery voltage, current and other parameters in real time and transmits the data to the main control chip. The main control chip processes the data according to a preset algorithm to determine the power status of the earphone. Under the control of the main control chip, the display screen 2 (digital display screen 2) displays the earphone power information to the user in a corresponding manner (such as light color change, digital display, etc.), so that the user can understand the power status in time and make reasonable arrangements for use and charging time. At the same time, the indicator light 21 can flash when charging or when the earphone body 1 is out of power, which serves as a warning. It should be noted that the installation, signal connection and working principle between the display screen 2 and the indicator light 21 and the earphone body 1 are all existing technologies and will not be described here.

[0050] like Figure 10 As shown, combined with Figures 1 to 9 As shown, this embodiment also provides a wireless earphone case, including a case body 12, which is used to store the aforementioned wireless earphones with battery level display.

[0051] Working principle:

[0052] When the user receives the headphones, the ear hook 41, connecting rod 42, retaining ring 43, and adjusting rod 10 are in their default assembled state. The adjusting rod 10 is located in the adjusting groove 11 of the ear hook 41. The adjusting component 9 positions the limiting groove 13 on the adjusting rod 10. When the user needs to wear the headphones, they can adjust the ear hook 4 by holding the ear hook 41 and connecting rod 42 according to their own ear shape. Since the retaining ring 43 is an arc-shaped structure and is locked and rotated at the connection between the earbud 3 and the headphone body 1, the user can rotate the retaining ring. Ring 43 adjusts the angle between the ear hook 4 and the earphone body 1 to accommodate different wearing habits and ear fit requirements. Simultaneously, when adjusting the size of the ear hook 4, the user rotates the handle 22 to drive the worm gear, which in turn drives the worm wheel to rotate, thereby rotating the second rotating shaft 945. When the second rotating shaft 945 rotates, it drives the rotating plate 944 to rotate, and its other end pushes the first rotating shaft 943 to slide within the drive groove 942, forcing the drive plate 941 to move away from the movable plate 92. The movable rod 93 then drives the movable... As plate 92 moves away from adjusting rod 10, compressing spring 16, limiting block 91 disengages from limiting groove 13 of adjusting rod 10. At this time, adjusting rod 10 is unlocked and can slide freely in adjusting groove 11. The user pulls or pushes connecting rod 42 according to ear size, causing adjusting rod 10 to slide in adjusting groove 11 of ear hook rod 41, changing the relative length of ear hook rod 41 and connecting rod 42 until ear hook 4 fits the ear. After the position is adjusted, the user drives worm gear to rotate through handle 22 in the opposite direction. Spring 16 pushes movable plate 92 to reset, causing limiting block 91 to re-embed into a limiting groove 13 of adjusting rod 10, completing the locking. The retaining ring 43 is rotated at the connection between earbud 3 and headphone body 1, allowing ear hook 4 to rotate relative to headphone body 1, achieving multi-angle adjustment. At the same time, the setting of adjusting component 9, adjusting rod 10 and limiting groove 13 allows the user to accurately adjust the size of ear hook 4 according to their own ear size, improving the versatility of the device and enhancing the user experience.
