[0023] Currently, the C-bridge of clip-on headphones typically consists of a memory steel wire, wiring, and a soft rubber covering the memory steel wire and wiring. The inventors discovered that existing clip-on headphones are not very comfortable to wear. Specifically, when existing clip-on headphones are worn by users with larger ears, although the elasticity of the C-bridge can hold the headphones on the ears, the clamping force is too strong, causing ear pain after prolonged wear. When existing clip-on headphones are worn by users with smaller ears, the clamping force is too weak, resulting in a loose fit and poor stability. To solve this technical problem, the inventor attempted to design a new clip-on earphone and unexpectedly discovered that by using a C-bridge spring to replace the structure made of memory steel wire and soft rubber, the first end of the C-bridge spring is slidably connected to the first shell, and a spring bead is set on the first shell. Multiple grooves are arranged at intervals along the sliding direction on the side of the first end of the C-bridge spring facing the spring bead. In this way, when the user wears the clip-on earphone, they can choose a suitable groove to fit the spring bead according to their own ear size. By adjusting the distance between the first shell and the second shell, it can accommodate users with different ear sizes, improving the user's wearing comfort and versatility.

[0024] Based on this, the present invention provides a clip-on earphone. Figures 1 to 7 This invention provides a specific embodiment of the clip-on earphone.

[0025] Please see Figures 1 to 7The clip-on earphone 100 provided by this utility model includes a first shell 1, a second shell 2, a C-bridge spring 3, a speaker module 51, and power supply and control components. (See reference...) Figure 3 The C-bridge spring 3 has a first end 31 and a second end 32 at its two ends. The first end 31 is slidably connected to the first housing 1, and the second end 32 is connected to the second housing 2. (See reference...) Figure 4 The first housing 1 is provided with a spring bead 11, see reference. Figure 3 and Figure 5 The first end 31, facing the spring bead 11, has a plurality of grooves 311 spaced apart along the sliding direction. During the sliding stroke of the first housing 1 relative to the first end 31, one of the plurality of grooves 311 selectively engages with the spring bead 11 for limiting and positioning. (See reference...) Figure 7 The speaker module 51 is housed in one of the first housing 1 and the second housing 2, and the power supply and control component is housed in the other of the first housing 1 and the second housing 2. The power supply and control component is electrically connected to the speaker module 51 via wiring 4.

[0026] In the technical solution provided by this utility model, a spring bead 11 is provided on the first housing 1. Multiple grooves 311 are spaced apart along the sliding direction on the side of the first end 31 of the C-bridge spring piece 3 facing the spring bead 11. During the sliding stroke of the first housing 1 relative to the first end 31, one of the multiple grooves 311 can selectively engage with the spring bead 11 for limiting. Thus, the user can select a suitable groove 311 to engage with the spring bead 11 according to their ear size, thereby adjusting the distance between the first housing 1 and the second housing 2 to accommodate users with different ear sizes, improving user comfort and versatility.

[0027] See Figure 7 In this embodiment, the speaker module 51 is housed in the first housing 1, and the power supply and control components are housed in the second housing 2.

[0028] The spring-loaded ball 11 includes a housing, a spring, and a ball. The housing has a mounting groove, and the ball is movably disposed within the mounting groove. The spring connects the ball to the bottom of the mounting groove. When the spring is not subjected to external force, the ball at least partially protrudes from the mounting groove.

[0029] It should be noted that the number of grooves 311 is not specifically limited and can be selected according to the actual situation. For example, this application has 3 grooves 311. Users can adjust 3 positions according to their needs, that is, adjust the first shell 1 to three different positions on the first end 31 to suit users with different ear sizes.

[0030] It is understandable that, since the spring bead 11 is elastic, after a certain groove 311 and the spring bead 11 have completed the limiting engagement, when it is necessary to release the limiting engagement between the groove 311 and the spring bead 11 so that the spring bead 11 can slide to engage with another groove 311, it is only necessary to apply a certain external force to the first housing 1 in the sliding direction to release the limiting engagement, which is convenient to operate.

[0031] It should be noted that the thickness of the C-bridge spring 3 and the distance between the first housing 1 and the second housing 2 are not specifically limited and can be selected according to actual conditions. For example, the thickness of the C-bridge spring 3 is designed to be 0.2 mm, and the distance between the first housing 1 and the second housing 2 is set to 2.85 mm. In addition, the height between the end of the first housing or the second housing opposite to the C-bridge spring 3 and the end of the C-bridge spring 3 opposite to the first housing can be designed to be 22.5-24 mm.

[0032] The following will describe, by way of example, a further specific implementation or refinement of the clip-on headphone 100, in order to further improve its efficiency, reliability or for other improvements.

[0033] In some embodiments, see Figure 4 The first housing 1 is provided with a mounting base 12, and the two opposite end faces of the mounting base 12 are respectively provided with sliding grooves 122. (See reference...) Figure 3 The two opposite sides of the first end 31 are slidably connected to the two grooves 122. The grooves 122 provide guidance for the sliding of the first housing 1 relative to the first end 31, precisely defining the relative movement trajectory between the first housing 1 and the first end 31, thereby improving the positioning accuracy of the limiting engagement between the spring bead 11 on the first housing 1 and the groove 311 on the first end 31. Specifically, the mounting base 12 includes two opposite mounting platforms 121 disposed on the first housing 1, and each of the two opposite end faces of the mounting platforms 121 is provided with a groove 122.

[0034] In some embodiments, see Figure 3 The first end 31 extends at least partially out of the slide groove 122, and two limiting portions 312 protrude from opposite sides of the first end 31, with the two limiting portions 312 located at the portions of the first end 31 extending out of the slide groove 122. The two limiting portions 312 prevent the first housing 1 from detaching from the first end 31 during the sliding process. This improves the stability of the connection between the first housing 1 and the first end 31.

[0035] In order to improve the limiting effect of the groove 311 and the spring bead 11, in some embodiments, the shape of the groove 311 is adapted to the shape of the spring bead 11.

[0036] Considering that the power supply and control components inside the second housing 2 of the clip-on earphone 100 are often more susceptible to damage and aging, in some embodiments, the second end 32 is detachably connected to the second housing 2. This allows the second housing 2 to be removed for individual repair or replacement, saving costs and ensuring good interchangeability. For details, please refer to... Figure 4 and Figure 5 The second housing 2 is provided with a slot 211, and the second end 32 is provided with a buckle 321 on the side facing the slot 211, and the slot 211 and the buckle 321 are engaged.

[0037] Considering that when a user wears the clip-on earphone 100, the wiring 4 itself can be bent at any angle, making its movement trajectory unpredictable as it moves with the C-bridge spring 3, and thus easily damaged by pulling, therefore, in some embodiments, see... Figure 5 The C-bridge spring 3 has a first through hole 33 and a second through hole 34 near the first end 31 and the second end 32, respectively. (See reference) Figure 3 One end of the connector 4 passes through the first through hole 33 and connects to the speaker module 51 inside the first housing 1, while the other end passes through the second through hole 34 and connects to the power supply and control components inside the second housing 2. The first through hole 33 and the second through hole 34 guide and limit the movement of the connector 4, ensuring its movement trajectory remains within a safe and controllable range, significantly improving its service life. Furthermore, both the first through hole 33 and the second through hole 34 are elongated holes, and their cross-sectional areas are larger than that of the connector 4, reducing wear between the connector 4 and the C-bridge spring 3, and also reducing abnormal noise.

[0038] To improve the comfort of the first housing 1 when worn inside the ear, in some embodiments, please refer to... Figure 1 and Figure 2 The first housing 1 is spherical in shape to fit the curvature of the auricle.

[0039] In some embodiments, see Figure 6 The first housing 1 is provided with a sound outlet 13, and a sound outlet mesh 131 is provided on the inner side of the sound outlet 13. The sound outlet mesh 131 can absorb or reflect part of the sound waves to improve the sound quality and timbre. The sound outlet 13 is located on the side of the first housing 1 opposite to the first end 31. A fixing part 17 for fixing the sound outlet mesh 131 is provided on the outer side of the sound outlet 13.

[0040] See Figure 1 and Figure 7The first housing 1 includes an upper housing 18 and a lower housing 19, the upper housing 18 and the lower housing 19 being interconnected and forming a receiving cavity between them, and the speaker module 51 being housed within the receiving cavity. (See also...) Figure 4 and Figure 7 The second housing 2 includes a cylindrical body 21 and a front cover 22 and a rear cover 23 covering both ends of the cylindrical body 21. The power supply and control components are housed inside the cylindrical body 21.

[0041] In some embodiments, see Figure 7 The power supply and control components include a battery 62, a PCBA board 61, and a touch and antenna FPC 63. The battery 62 and the touch and antenna FPC 63 are respectively located on opposite sides of the PCBA board 61, making full use of the space on both sides of the PCBA board 61 and improving the product's integration. The PCBA board 61 is electrically connected to the battery 62 and the touch and antenna FPC 63. The touch and antenna FPC 63 is used to receive touch signals and can transmit the received touch signals to the PCBA board 61 to realize touch control functions. Specifically, by touching the outer side of the front cover 22 corresponding to the antenna and touch FPC, touch control of the headphones can be achieved. In addition, an EVA foam pad 65 is provided between the battery 62 and the PCBA board 61, which can play a role in cushioning, shock absorption, and insulation.

[0042] In some embodiments, see Figure 7The first housing 1 houses a microphone assembly 14, which is electrically connected to the power supply and control components. Specifically, the microphone assembly 14 is electrically connected to the PCBA board 61. The microphone assembly 14 is positioned close to the sound outlet 13. Thus, the microphone assembly 14 can simultaneously use the sound outlet 13 as a receiver, converting the received sound into an electrical signal and transmitting it to the PCBA board 61, thereby receiving external sound. This eliminates the need for a separate microphone hole, improving the dustproof and waterproof properties of the first housing 1. Furthermore, the second housing 2 houses a noise-canceling microphone assembly 64, which is electrically connected to the PCBA board 61. The microphone assembly 14 collects human voice, while the noise-canceling microphone assembly 64 collects background noise. This protects the target voice in the primary direction during calls and removes various environmental noises, such as other people's voices, traffic noise, and wind noise, effectively suppressing reverse environmental noise. This allows the wearer to communicate more freely with reduced environmental noise interference. Since the sound received by the noise reduction microphone component 64 needs to be different from the sound received by the call microphone component 14 in order to facilitate the removal of background noise, in this application, the call microphone component 14 is located in the first housing 1 and the noise reduction microphone component 64 is located in the second housing 2, so that there is a sufficient distance between the call microphone component 14 and the noise reduction microphone component 64, thereby improving the call noise reduction effect.

[0043] When the speaker module 51 vibrates, the air pressure inside the first housing 1 increases, thereby increasing the resistance to diaphragm vibration in the speaker module 51, making the headphone sound muffled and lacking clarity. In some embodiments, see [reference needed]. Figure 4 A rear cavity 15 is provided on the side of the first housing 1 opposite to the sound outlet 13, and a dustproof mesh 16 is provided on the inner side of the rear cavity 15. The rear cavity 15 allows airflow and prevents pressure buildup inside the first housing 1, resulting in clearer and more transparent sound quality. The dustproof mesh 16 ensures that the rear cavity 15 is breathable while blocking external impurities, thus improving the lifespan of the clip-on earphone 100.

[0044] In some embodiments, the power supply and control components further include a charging copper pillar assembly 67, which includes two charging copper pillars and an FPC connector. The two charging copper pillars are fixed to the rear cover 23, and a waterproof gasket 68 is provided between the two charging copper pillars and the rear cover 23. The waterproof gasket 68 is made of waterproof PORON cotton, which has both compression resilience and waterproof sealing functions. The two charging copper pillars are respectively connected to the battery 62 through the FPC connector. An EVA foam gasket 65 is provided between the battery 62 and the FPC connector, which can play a role in cushioning, shock absorption, and insulation.

[0045] In some embodiments, the clip-on earphone 100 further includes an earphone magnet 66, which is fixed to the inside of the back cover 23 for positioning and fixing to ensure the earphone is in the correct position in the charging case.

[0046] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
