Description

Technical Field

[0001] This application relates to the technical field of headphones, and in particular to a highly adaptable clip-on headphone. Background Technology

[0002] Headphones are everyday audio devices and come in many types, such as in-ear, over-ear, earbuds, wireless Bluetooth headphones, and clip-on headphones. Different types are suitable for different usage scenarios.

[0003] The traditional connection between the C-bridge (the lateral support structure connecting the two listening ends) and the listening end of clip-on headphones is mostly a fixed connection (such as one-piece molding or rigid screw locking). However, this connection method has certain drawbacks: poor angle adaptability: it cannot adjust the angle of the listening end according to the user's wearing posture (such as tilting the head or looking down), which can easily lead to "the listening end deviating from the ear canal, affecting sound quality transmission" or "interference with the ear contour, creating a feeling of pressure"; cumbersome adjustment operation: some adjustable structures require tools (such as Allen wrenches) or rely on complex damping components, which is inconvenient for users and the reliability of adjustment decreases after long-term use; structural redundancy: some adjustment schemes introduce too many electronic control or complex mechanical parts, increasing the weight and production cost of the headphones and hindering portability. Therefore, it is necessary to propose a highly adaptable clip-on headphone to solve the above problems. Utility Model Content

[0004] To address the issues of poor angle adaptability, cumbersome adjustment operations, and structural redundancy in the traditional fixed connection method between the C-bridge and the listening end of existing clip-on headphones, this application provides a highly adaptable clip-on headphone.

[0005] This application provides a highly adaptable clip-on earphone, which adopts the following technical solution: A highly adaptable clip-on earphone includes an outer listening component and an inner listening component on the right side of the outer listening component. The top of the outer listening component and the top of the inner listening component are connected by a C-bridge structure. A connecting block is fixedly installed at the bottom of the C-bridge structure on the left side of the inner listening component. The connecting block is fitted into the interior of the outer listening component. A limiting plate is fixedly installed on the outer surface of the connecting block. A locking post is slidably connected to the interior of the outer listening component at the bottom of the limiting plate. A spring is fixedly installed around the locking post. The left side of the spring is fixedly connected to the inner wall of the outer listening component. Several slots are opened on the outer surface of the connecting block at the bottom of the limiting plate. The locking post is fitted into one of the slots.

[0006] By setting a connecting block, the C-bridge structure and the external listening device can be movably connected. The connecting block can rotate inside the external listening device, thereby allowing the angle of the internal listening device to be adjusted arbitrarily. Furthermore, the elasticity of the spring itself can create a rightward push on the locking post, causing it to insert into the interior of the connecting block. This allows for quick positioning of the C-bridge structure, replacing the existing one-piece molding and screw-based rigid locking structure. This facilitates the adjustment of the angle of the internal listening device to accommodate different wearing postures of the user.

[0007] A further improvement of the technical solution of this application is that: an anti-slip pad is attached to the right side surface of the snap-fit ​​post, and a contact pad is attached inside each slot of the connecting block, with the anti-slip pad and the outer surface of a contact pad pressing against each other.

[0008] By adopting the above technical solution, the friction between the locking post and the inner wall of the connecting block can be increased by setting anti-slip pads and contact pads, reducing the possibility of the connecting block and the locking post separating, thereby improving the limiting effect on the connecting block.

[0009] A further improvement of the technical solution of this application is that: the left side surface of the anti-slip pad is provided with a number of second protrusions, and the outer side surface of the contact pad is provided with a number of first protrusions.

[0010] By adopting the above technical solution, the surface of the anti-slip pad and the contact pad in contact is improved from a flat surface to an uneven surface by opening the second protrusion and the first protrusion, which further increases the friction between the snap-fit ​​post and the surface of the connecting block, thereby further improving the limiting effect on the connecting block.

[0011] A further improvement to the technical solution of this application is that the left side of the snap-fit ​​post extends into the interior of the external listening component, and a pull buckle is fixedly installed on the left side of the snap-fit ​​post.

[0012] In the above technical solution, the contact area between the operator's hand and the locking pin can be increased by setting a pull buckle, so that the locking pin can be pulled to the left to separate the locking pin from the inside of the connecting block, so as to facilitate the adjustment of the connecting block.

[0013] A further improvement of the technical solution of this application is that: an opening is provided on the surface of the connecting block on the outer side of the contact pad, and the opening is larger than the cross-sectional area of ​​the right side of the snap-fit ​​post.

[0014] By adopting the above technical solution, by opening an opening larger than the surface of the snap-fit ​​post, it is possible to easily align the snap-fit ​​post and insert it into the slot, reducing the possibility of snapping and further facilitating the limiting treatment of the connecting block.

[0015] A further improvement of the technical solution of this application is that a lower ball bearing is rolled on the bottom of the connecting block, and the baffle of the lower ball bearing is rolledly connected to the inner wall of the outer listening component.

[0016] By adopting the above technical solution, the bottom of the connecting block can be separated from the inner wall of the outer listening component by setting the lower ball bearing. During the rotation of the connecting block, the lower ball bearing can roll synchronously, thereby reducing the wear between the connecting block and the outer listening component and extending their service life.

[0017] A further improvement of the technical solution of this application is that: a number of first balls are rolled on the outer surface of the connecting block between the limiting plate and the locking post, and the outer side of the first balls is rolled in connection with the inner wall of the outer listening component; a number of upper balls are rolled on the outer surface of the connecting block at the top of the limiting plate, and the outer side of the upper balls is rolled in connection with the inner wall of the outer listening component.

[0018] By adopting the above technical solution, the outer periphery of the connecting block and the inner wall of the external listening component can be separated by setting the first ball and the upper ball. During the rotation of the connecting block, the first ball and the upper ball can roll synchronously, thereby further reducing the wear between the connecting block and the external listening component and extending their service life.

[0019] A further improvement of the technical solution of this application is that: a number of side balls are rolled on the outer side of the limiting plate, and the outer side of the side balls are rolledly connected to the inner wall of the outer listening component; a number of second balls are rolled on the top and bottom of the limiting plate, and the second balls are rolledly connected to the inner wall of the outer listening component.

[0020] By adopting the above technical solution, the outer surface of the limiting plate can be separated from the inner wall of the outer listening component by setting side balls and second balls. During the rotation of the limiting plate, the side balls and second balls can roll synchronously, thereby reducing the wear between the limiting plate and the outer listening component and extending their service life.

[0021] In summary, this application includes at least the following beneficial technical effects: 1. This application provides a highly adaptable clip-on earphone. By rotating the connecting block inside the outer listening component, the C-bridge structure can be movably connected to the outer listening component, thereby allowing arbitrary adjustment of the angle of the inner listening component. Furthermore, by using a spring to push the locking post to the right, it can be inserted into the interior of the connecting block, thereby quickly limiting the C-bridge structure. This replaces the existing one-piece molding and screw-based rigid locking structure, thus adapting to different wearing postures of the user.

[0022] 2. This application provides a highly adaptable clip-on earphone. By setting a plurality of lower ball bearings, upper ball bearings, and a first ball bearing, the connecting block can be separated from the inner wall of the outer listening component. By setting a side ball bearing and a second ball bearing, the limiting plate can be separated from the inner wall of the outer listening component. Furthermore, the lower ball bearings, upper ball bearings, and first ball bearings can roll synchronously during the rotation of the connecting block. During the rotation of the limiting plate, the second ball bearing and the side ball bearings can roll synchronously. This reduces the wear between the connecting block and the limiting plate and the outer listening component during multiple adjustments of the C-bridge structure and the inner listening component, and extends their service life.

[0025] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0026] Example 1 See Figure 1 , Figure 2 and Figure 3 This application provides a highly adaptable clip-on earphone, including an external listening component 1, an internal listening component 3 on the right side of the external listening component 1, the top of the external listening component 1 and the top of the internal listening component 3 connected by a C-bridge structure 2, a connecting block 4 fixedly installed at the bottom of the C-bridge structure 2 on the left side of the internal listening component 3, the connecting block 4 fitting into the interior of the external listening component 1, a limiting plate 5 fixedly installed on the outer surface of the connecting block 4, a locking post 6 slidably connected inside the external listening component 1 at the bottom of the limiting plate 5, a spring 7 fixedly installed around the periphery of the locking post 6, the left side of the spring 7 fixedly connected to the inner wall of the external listening component 1, and several slots opened on the outer surface of the connecting block 4 at the bottom of the limiting plate 5, the locking post 6 fitting into one of the slots.

[0027] In this embodiment, by setting the connecting block 4, the C-bridge structure 2 and the outer listening component 1 can be movably connected. The connecting block 4 can rotate inside the outer listening component 1, thereby allowing the angle of the inner listening component 3 to be adjusted arbitrarily. Furthermore, the elastic force of the spring 7 itself can generate a rightward push on the locking post 6, causing it to insert into the interior of the connecting block 4. This allows for quick positioning of the C-bridge structure 2, replacing the existing one-piece molding and screw-based rigid locking structure. This facilitates the adjustment of the angle of the inner listening component 3 to adapt to different wearing postures of the user.

[0028] Example 2 See Figure 2 , Figure 3 and Figure 4 Based on Embodiment 1, this application provides the following technical solution: Preferably, an anti-slip pad 9 is attached to the right side surface of the snap-fit ​​post 6, and a contact pad 10 is attached inside each slot of the connecting block 4. The anti-slip pad 9 and the outer surface of a contact pad 10 are pressed against each other. A plurality of second protrusions 18 are provided on the left side surface of the anti-slip pad 9, and a plurality of first protrusions 16 are provided on the outer surface of the contact pad 10. The left side of the snap-fit ​​post 6 extends into the interior of the external listening component 1, and a pull buckle 8 is fixedly installed on the left side of the snap-fit ​​post 6. An opening 17 is provided on the surface of the connecting block 4 outside the contact pad 10, and the opening 17 is larger than the cross-sectional area of ​​the right side of the snap-fit ​​post 6.

[0029] In this embodiment, by providing the anti-slip pad 9 and the contact pad 10, the friction between the locking post 6 and the inner wall of the connecting block 4 can be increased, reducing the possibility of the connecting block 4 separating from the locking post 6, thereby improving the limiting effect on the connecting block 4. By providing the second protrusion 18 and the first protrusion 16, the contact surface between the anti-slip pad 9 and the contact pad 10 is improved from a flat surface to an uneven surface, further increasing the friction between the locking post 6 and the surface of the connecting block 4, thereby further improving the limiting effect on the connecting block 4. By providing the pull buckle 8, the contact area between the operator's hand and the locking post 6 can be expanded, so that the locking post 6 can be pulled to the left, so that the locking post 6 separates from the interior of the connecting block 4, so as to facilitate the adjustment of the connecting block 4. By providing an opening 17 larger than the surface of the locking post 6, the locking post 6 can be easily aligned and inserted into the slot, reducing the possibility of jamming, thereby further facilitating the limiting treatment of the connecting block 4.

[0030] Example 3 See Figure 2 , Figure 3 and Figure 4Based on Embodiment 2, this application provides the following technical solution: Preferably, a lower ball bearing 11 is rolledly installed at the bottom of the connecting block 4, and the baffle of the lower ball bearing 11 is rolledly connected to the inner wall of the outer listening component 1; a plurality of first balls bearing 13 are rolledly installed on the outer surface of the connecting block 4 between the limiting plate 5 and the locking post 6, and the outer side of the first balls bearing 13 is rolledly connected to the inner wall of the outer listening component 1; a plurality of upper balls bearing 12 are rolledly installed on the outer surface of the connecting block 4 at the top of the limiting plate 5, and the outer side of the upper balls bearing 12 is rolledly connected to the inner wall of the outer listening component 1; a plurality of side balls bearing 14 are rolledly installed on the outer side of the limiting plate 5, and the outer side of the side balls bearing 14 is rolledly connected to the inner wall of the outer listening component 1; a plurality of second balls bearing 15 are rolledly installed at both the top and bottom of the limiting plate 5, and the second balls bearing 15 are rolledly connected to the inner wall of the outer listening component 1.

[0031] In this embodiment, by setting the lower ball bearing 11, the bottom of the connecting block 4 can be separated from the inner wall of the outer listening component 1. During the rotation of the connecting block 4, the lower ball bearing 11 can roll synchronously, thereby reducing the wear between the connecting block 4 and the outer listening component 1 and extending their service life. By setting the first ball bearing 13 and the upper ball bearing 12, the outer periphery of the connecting block 4 can be separated from the inner wall of the outer listening component 1. During the rotation of the connecting block 4, both the first ball bearing 13 and the upper ball bearing 12 can roll synchronously, thereby further reducing the wear between the connecting block 4 and the outer listening component 1 and extending their service life. By setting the side ball bearing 14 and the second ball bearing 15, the outer surface of the limiting disk 5 can be separated from the inner wall of the outer listening component 1. During the rotation of the limiting disk 5, both the side ball bearing 14 and the second ball bearing 15 can roll synchronously, thereby reducing the wear between the limiting disk 5 and the outer listening component 1 and extending their service life.

[0032] The working principle of this highly adaptable clip-on headphone is explained in detail below.

[0033] like Figures 1-4 As shown, depending on their own usage habits, users can pull the latch 8 to the left to separate the locking post 6 from the inside of the connecting block 4, and then rotate the connecting block 4 to adjust the position of the inner listening element 3 to suit the user's needs. After adjustment, the operator can release the latch 8. At this time, the spring 7 can pull the locking post 6 to the right to insert it into a slot of the connecting block 4. At the same time, the anti-slip pad 9 and the contact pad 10 press against each other, thereby quickly limiting the connection block 4 to ensure normal use of the outer listening element 1 and the inner listening element 3.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
