Description

Technical Field

[0001] The utility model relates to the technical field of ear clip type earphones, in particular to a C-shaped bridge structure of the ear clip type earphones. Background Art

[0002] Traditional ear-hook headphones are actually in-ear headphones. They use the tragus to fix the headphones to a certain extent. The headphones cannot be locked on the ears again, and cannot achieve a good anti-falling effect. After being worn in the ears for a long time, the ear holes are blocked for a long time, which will cause the sound to directly impact the eardrum and damage the eardrum, causing ear pain and even causing more other ear diseases, greatly reducing the comfort of Bluetooth headphones.

[0003] In light of this, and to address the aforementioned issues, ear-clip headphones have emerged on the market, such as those with authorization publication number CN220023018U. These headphones specifically include a U-shaped ear hook, an earphone body positioned at one end of the U-shaped ear hook, and an ear clip positioned at the other end of the U-shaped ear hook. The U-shaped ear hook is capable of elastically deforming to change the distance between the earphone body and the ear clip. Both the earphone body and the ear clip are equipped with magnetic elements to attract each other under magnetic force. The earphone body is equipped with a speaker, the ear clip is equipped with a battery cell and a motherboard electrically connected to the battery cell, and a wire is passed through the U-shaped ear hook, connecting the speaker and the motherboard.

[0004] However, there is still room for improvement in the above-mentioned ear-clip headphones. For example, the connection between the wire and the U-shaped ear hook is generally pre-embedded, specifically by first placing the wire into a mold, and then forming the U-shaped ear hook on the wire through injection molding. However, this design has some disadvantages. For example, some headphones have many functions, so these wires generally contain many different types of signal transmission wires. However, some wires are easily damaged under high temperature conditions, which will reduce the performance of the wire. However, since the plastic in the injection molding process is often hot, it is easy to cause some wires in the wire to be damaged, which in turn increases the defective rate.

[0005] Therefore, there is a need to improve the existing technology. Utility Model Content

[0006] In response to the problems existing in the above-mentioned prior art, the purpose of the present invention is to provide a C-shaped bridge structure for ear-clip headphones, which eliminates the need for pre-embedded wires in the C-shaped bridge during injection molding. Instead, the wires are installed on the C-shaped bridge later. This prevents the wires from being damaged by the high temperature during the injection molding process, effectively ensuring the performance of the wires and improving the yield rate.

[0007] In order to achieve the above purpose, the technical solution of the utility model is:

[0008] A C-shaped bridge structure for an earclip headphone comprises a C-shaped bridge, a conductive wire, and a lubricating coating. A wire passage cavity is provided within the C-shaped bridge, extending through both ends of the bridge. The lubricating coating is matchedly coated over the conductive wire, and the conductive wire can pass through the wire passage cavity by utilizing the lubricity of the lubricating coating, thereby protecting the conductive wire from damage caused by the high temperature of the C-shaped bridge during injection molding.

[0009] Furthermore, a shaping piece is included; the shaping piece is pre-buried inside the C-shaped bridge and is used to make the C-shaped bridge more stably maintain in the clamping shape. The above arrangement can be used to make the C-shaped bridge more stably maintain in the clamping shape.

[0010] Furthermore, the shaping piece is made of titanium wire, molybdenum steel, spring steel or titanium-nickel alloy, so that the use effect of the shaping piece can be guaranteed.

[0011] Furthermore, after both ends of the wire are located outside the wire cavity, the portion of the lubricating covering tape that leaks out of the wire cavity can be torn off to expose the two ends of the wire, so that the wire can be connected to the earphone body and the ear clip accordingly. That is, after the lubricating covering tape is torn off, it can be prevented from affecting the installation of other components.

[0012] Furthermore, the lubricating covering tape is made of polytetrafluoroethylene paper so that the lubricating covering tape has self-lubricating properties to facilitate movement in the wire passage cavity.

[0013] Furthermore, the C-shaped bridge includes a C-shaped main body and two connecting parts respectively arranged at both ends of the main body; a hook is provided on each of the connecting parts so as to utilize the hook to cooperate with other components.

[0014] The beneficial effects of the utility model are:

[0015] The present invention provides a wire-passing cavity that runs through both ends of the C-shaped bridge. After the wire is coated with a layer of lubricating coating tape, the lubricity of the lubricating coating tape can be utilized to smoothly pass the wire through the wire-passing cavity. In addition, after the wire is passed through, the lubricating coating tape exposed in the wire-passing cavity can be torn off, thereby exposing both ends of the wire for subsequent assembly. Due to the design of the present invention, the wire does not need to be pre-buried in the C-shaped bridge during injection molding, but is instead installed on the C-shaped bridge afterward. Therefore, the wire material of the wire will not be damaged by the high temperature of the injection molding process, effectively ensuring the performance of the wire and improving the yield rate.

[0027] The utility model will be further described below with reference to the accompanying drawings and specific embodiments. The following description is merely illustrative and does not limit the scope of protection of the utility model.

[0028] Example 1:

[0029] like Figure 1 and Figure 8As shown, a C-shaped bridge structure for an earclip headphone comprises a C-shaped bridge 1, a conductor 2, and a lubricating coating 3. A wire passage cavity 4 is provided within the C-shaped bridge 1, extending through both ends of the bridge 1. The lubricating coating 3 is matchedly coated around the conductor 2, allowing the conductor 2 to pass through the passage cavity 4, utilizing the lubricity of the lubricating coating 3. This protects the conductor 2 from the high temperatures experienced during the injection molding of the C-shaped bridge 1. In this embodiment, the conductor 2 comprises multiple signal transmission lines and an insulating layer covering the outer surface of the multiple signal transmission lines. Therefore, this arrangement effectively protects the conductor 2.

[0030] In this embodiment, the C-shaped bridge 1 is made of TPU, so that the C-shaped bridge 1 has a certain elasticity, so that when it is driven by an external force, the C-shaped bridge 1 will deform to facilitate clamping the ear.

[0031] Preferably, the present invention further includes a shaping member 5; the shaping member 5 is pre-embedded within the C-shaped bridge 1 and is used to maintain the C-shaped bridge 1 in a more stable clamping configuration. Specifically, the shaping member 5 can also change its own configuration when subjected to force, and deform and recover to its original position when the external force is removed. The shaping member 5 has a certain stability, which allows the C-shaped bridge 1 to maintain a certain state more stably. Therefore, during the use of the earphone clamp, it can allow the earphone to be clamped on the ear more stably. Moreover, the provision of the shaping member 5 can enable the C-shaped bridge 1 structure to maintain long-term elasticity, that is, ensure that the C-shaped bridge 1 has a sufficient clamping force, thereby ensuring the normal use of the earphone.

[0032] Preferably, the shaping member 5 is titanium wire, molybdenum steel, spring steel or titanium-nickel alloy, etc. However, those skilled in the art will appreciate that the shaping member 5 can also be made of other memory metals, as long as the shaping member 5 maintains a certain degree of deformation elasticity.

[0033] like Figure 1 and Figure 9 As shown, during use, after both ends of the wire 2 are located outside the wire cavity 4, the portion of the lubricating covering tape 3 that leaks out of the wire cavity 4 can be torn off (that is, the lubricating covering tape 3 that is inconvenient to remove can be left in the wire cavity 4) to expose the two ends of the wire 2, so that the wire 2 can be connected to the earphone body 7 and the ear clip 8 respectively.

[0034] In this embodiment, the lubricating coating tape 3 is made of polytetrafluoroethylene paper. Polytetrafluoroethylene (PTFE) paper has many advantages, making it an ideal material for many industrial and commercial applications. The following are some of the main advantages of polytetrafluoroethylene (PTFE) paper: High temperature resistance: Polytetrafluoroethylene (PTFE) paper can withstand temperatures up to 260°C or even higher, making it suitable for use in high-temperature environments. Chemical inertness: It has extremely strong tolerance to most chemicals and hardly reacts with any chemicals, making it very suitable for use in corrosive environments. Low friction coefficient: It has an extremely low friction coefficient and exhibits excellent self-lubricating properties, which can reduce wear and energy consumption between mechanical parts. Non-stickiness: The surface is very smooth and not easy to adhere to other substances, making it easy to clean and maintain. Excellent electrical insulation: It has good electrical insulation properties and performs well in electrical and electronic applications. Weather resistance: It has good resistance to ultraviolet rays, moisture and oxidants, making it suitable for use outdoors and in harsh environments. Therefore, it is precisely because of the various advantages mentioned above that polytetrafluoroethylene (PTFE) paper is widely used in many fields.

[0035] Preferably, the C-shaped bridge 1 comprises a C-shaped main body 11 and two connecting portions 12 disposed at either end of the main body 11. Each connecting portion 12 is provided with a hook 121. Therefore, the two connecting portions 12 can be used to connect to the earphone body 7 and the ear clip 8, respectively. Specifically, the earphone body 7 and the ear clip 8 can be mated with the hooks 121 on the two connecting portions 12 to ensure stability.

[0036] More specifically, the two connecting parts 12 are respectively covered on the two ends of the shaping member 5, and in order to improve the stability between the two, the two ends of the shaping member 5 can also be set to be bent, so that after the connecting parts 12 cover the ends of the shaping member 5, the positioning member 5 is not easy to loosen.

[0037] In summary, the C-shaped bridge structure of the present invention provides a wire-passing cavity 4 that runs through both ends of the C-shaped bridge 1, and then after the wire 2 is coated with a layer of lubricating coating tape 3, the lubricity of the lubricating coating tape 3 can be utilized to smoothly pass the wire 2 into the wire-passing cavity 4. In addition, after the wire 2 is passed through, the lubricating coating tape 3 exposed in the wire-passing cavity 4 can be torn off, so that the two ends of the wire 2 can be exposed for subsequent assembly. Due to the design of the present invention, the wire 2 does not need to be pre-buried in the C-shaped bridge 1 during injection molding, but is instead installed on the C-shaped bridge 1 afterwards. Therefore, the wire material of the wire 2 will not be damaged by the high temperature during the injection molding process, effectively ensuring the performance of the wire 2 and improving the yield rate.

[0038] Example 2:

[0039] The utility model also discloses a method for manufacturing a C-shaped bridge of an ear clip-on earphone, which is used to manufacture the C-shaped bridge structure of the ear clip-on earphone, and specifically comprises the following steps:

[0040] S1, such as Figure 2 As shown, the shaping piece 5 and the forming strip 6 with lubricating oil on the surface are respectively clamped at the preset positions of the mold cavity of the mold, and the length of the forming strip 6 is longer than the length of the shaping piece 5; in addition, the provision of lubricating oil is to facilitate the subsequent removal of the forming strip 6;

[0041] S2, such as Figure 3-Figure 5 As shown, a C-shaped bridge 1 is injected, and the C-shaped bridge 1 completely covers the molding 5 and the middle part of the molding strip 6;

[0042] S3, such as Figure 6 As shown, the molding strip 6 is pulled out, thereby forming a wire passage cavity 4 running through both ends of the C-shaped bridge 1. Therefore, the actual function of the molding strip 6 is to facilitate the formation of the wire passage cavity 4 after the C-shaped bridge 1 is injection molded. As for the specific selection of the molding strip 6, a high-temperature resistant plastic strip can be selected. In addition, in order to improve the rigidity of the molding strip 6, a metal wire can be added therein so that the molding strip 6 can be pulled out more conveniently without being easily broken.

[0043] S4, such as Figure 7 As shown, a layer of lubricating coating tape 3 is correspondingly coated on the outer surface of the wire 2, so that the lubricating properties of the lubricating coating tape 3 can be utilized to facilitate the insertion of the wire 2 into the wire cavity 4, and the material is not easily stuck. Therefore, due to the lubricity of the lubricating coating tape 3, it can be easily moved in the wire cavity 4; specifically, the length of the lubricating coating tape 3 is preferably set to be longer than the length of the wire 2, and both ends of the lubricating coating tape 3 extend outward to the outside of the two ends of the wire 2; of course, the diameter of the wire 2 is similar to the diameter of the wire cavity 4, and the main function of the lubricating coating tape 3 is to improve the smoothness of the wire 2 when it penetrates the wire cavity 4;

[0044] S5, such as Figure 8 As shown, the wire 2 is inserted into the wire cavity 4 through the lubricating coating tape 3 until both ends of the wire 2 are located outside the two ends of the wire cavity 4; it should be noted that, in order to facilitate the insertion of the lubricating coating tape 3, before it is inserted into the wire cavity 4, the part of the lubricating coating tape 3 extending outside the end of the wire 2 can be pinched narrowed, for example, it can be pinched into a cone shape, that is, the part will form a shape with a width smaller than the width of the wire 2 (at the same time, the width of the lubricating coating tape 3 will also be smaller than the width of the wire cavity 4), so that it can be easily inserted into the wire cavity 4.

[0045] Of course, before installing the earphone body 7 and the ear clip 8 at both ends of the wire 2, the outer surface of the C-shaped bridge 1 can also be sprayed with corresponding colors to produce a C-shaped bridge with richer colors, so that it can cater to the aesthetic tastes of different people.

[0046] Finally, if Figure 1 As shown, the lubricating tape 3 on both ends of the wire 2, which is located outside the wire cavity 4, is torn off to expose the two ends of the wire 2 (that is, the lubricating tape 3 that is inconvenient to remove may remain in the wire cavity 4), so that the two ends of the wire 2 can be used to connect the earphone body 7 and the ear clip 8 respectively. Figure 9 As shown, the nozzle 122 is then removed and the earphone body 7 and the ear clip 8 are installed respectively to complete the assembly of the earphone.

[0047] In this embodiment, the C-shaped bridge 1 is also made of TPU, so that the C-shaped bridge 1 has a certain elasticity, so that when it is driven by external force, the C-shaped bridge 1 will deform to facilitate clamping the ears.

[0048] The following is a more detailed introduction:

[0049] In step S2, as Figure 3 As shown, when the C-shaped bridge 1 is injection molded, the first injection molding is performed to mold the two connecting parts 12 of the C-shaped bridge 1. The two connecting parts 12 are respectively covered on the two ends of the shaping member 5 and the two ends of the molding strip 6; specifically, the two ends of the shaping member 5 are respectively pre-embedded in the two connecting parts 12, and the two ends of the molding strip 6 are respectively passed through the two connecting parts 12; Figure 4 As shown, a second injection molding is then performed to mold the first portion 111 of the main body 11 of the C-shaped bridge 1 that completely covers the middle portion of the shaping member 5. The two ends of the first portion 111 of the main body 11 are respectively connected to the two connecting portions 12; Figure 5 As shown, a third injection molding is then performed to mold the second portion 112 of the main body 11 of the C-shaped bridge 1 that completely covers the middle portion of the molding strip 6. The side surface of the second portion 112 of the main body 11 is matched with the first portion 111 of the main body 11 and the two ends are respectively connected to the two connecting portions 12, thus forming a complete C-shaped bridge 1. Figure 3 As shown, after the first injection molding is completed, a sprue 122 can be injection-molded between the two connecting portions 12 to connect the two connecting portions 12, thereby ensuring that the shaped member 5 and the molding strip 6 can maintain their curved shape, thereby facilitating subsequent injection molding. Therefore, through the above steps, the C-shaped bridge 1 can be completely injection-molded and can be conveniently combined with the shaped member 5 and the molding strip 6.

[0050] like Figure 4As shown, in step S2, after the second injection molding, the first portion 111 of the main body 11 of the C-shaped bridge 1 still covers the side of the molding strip 6 that is closest to the molding member 5. This arrangement improves the stability of the molding strip 6 and prevents it from loosening or swinging. Simultaneously, at least one positioning strip 113 is injection-molded on the first portion 111 of the main body 11 of the C-shaped bridge 1, surrounding the other side of the molding strip 6. However, this positioning strip 113 is very thin and serves only to improve the stability of the molding strip 6.

[0051] In step S1, the lubricating oil is silicone oil to facilitate removal of the molding strip 6 in step S3. In step S4, the lubricating coating tape 3 is polytetrafluoroethylene paper to ensure self-lubrication and facilitate insertion into the wire passage cavity 4. However, those skilled in the art will appreciate that other materials may be used to replace the silicone oil and polytetrafluoroethylene paper if they can achieve the same effect.

[0052] Similarly, the above method is also achieved by providing a wire-passing cavity 4 that passes through both ends of the C-shaped bridge 1, and then after the conductor 2 is coated with a layer of lubricating coating tape 3, the lubricity of the lubricating coating tape 3 can be utilized to smoothly pass the conductor 2 through the wire-passing cavity 4. In addition, after the conductor 2 is passed through, the lubricating coating tape 3 exposed in the wire-passing cavity 4 can be torn off, so that the two ends of the conductor 2 can be exposed for subsequent assembly. The above design also makes it unnecessary for the conductor 2 to be pre-buried in the C-shaped bridge 1 during injection molding, but is instead installed on the C-shaped bridge 1 afterwards. Therefore, the wire material of the conductor 2 will not be damaged by the high temperature during the injection molding process, effectively ensuring the performance of the conductor 2 and improving the yield rate.

[0053] The present invention is not limited to the above-mentioned embodiments. If various changes or modifications to the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the scope of the claims and equivalent technologies of the present invention, the present invention is also intended to include these changes and modifications.
