Description

Technical Field

[0001] This utility model relates to the field of headphone cable technology, and in particular to a headphone signal cable structure. Background Technology

[0002] With the continuous development of electronic devices such as mobile phones and portable music players, headphones have become an indispensable accessory for these electronic products when you want to enjoy music. However, during the use of wired in-ear headphones, the stethoscope effect often occurs. The stethoscope effect is the noise generated by the headphone wire rubbing and vibrating with the outside world, such as clothing, and is directly transmitted into the ear canal through the headphone wire, affecting the listening experience.

[0003] In the prior art, the stethoscope effect is a very annoying and difficult problem to overcome in wired headphones and stethoscopes. The industry often hopes to reduce the friction between the cable and clothing by modifying the material and surface treatment of the cable sheath. However, no matter how the cable itself is modified, the friction always exists and the problem cannot be solved at its root. Therefore, we propose a headphone signal cable structure. Utility Model Content

[0004] The purpose of this invention is to solve the problem of stethoscope effect that easily occurs when headphone signal cables collide and rub during use, and to propose a new headphone signal cable structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An earphone signal cable structure includes a connecting cable and a connector disposed at the end of the connecting cable, and also includes a noise reduction component disposed on the connecting cable, wherein the diameter of the noise reduction component is three to five times the diameter of the connecting cable.

[0007] To improve the noise reduction effect, preferably, the diameter of the noise reduction component is four times the diameter of the connecting wire.

[0008] Preferably, the noise reduction component includes a counterweight, and the counterweight is made of ferrous metal.

[0009] Furthermore, the counterweight is a rotating structure, and the diameter of the counterweight is 8-12mm and the length is 18-22mm.

[0010] Furthermore, it also includes a protective sleeve that covers the counterweight and whose two ends are attached to the connecting wire.

[0011] To improve the ductility of the wire, preferably, the noise reduction component includes a cylindrical component spirally wound around the axis of the connecting wire, the axis of the cylindrical component coincides with the axis of the connecting wire, and both ends of the cylindrical component are integrally formed with the connecting wire.

[0012] Furthermore, the cylindrical component has 4-6 spiral turns.

[0013] Furthermore, the length of the cylindrical component from the connector is in the range of 3-7 cm.

[0014] Compared with the prior art, this utility model provides a headphone signal cable structure with the following advantages:

[0015] 1. The headphone signal cable structure is designed so that the metal counterweight is hidden by a protective sleeve covering the counterweight. The two ends of the protective sleeve are attached to the connecting cable to form an integrated structure. The material is preferably rubber or other polyurethane elastomer materials, which can further reduce the protrusion of the counterweight and reduce vibration, improve the aesthetics of the entire signal cable and reduce the stethoscope effect.

[0016] 2. The headphone signal cable structure, through the cylindrical component formed by the connecting cable wrapped around itself multiple times, not only ensures noise reduction but also further enhances the integrity of the signal cable and gives it a certain degree of flexibility, making the signal cable more convenient to use.

[0017] 3. The headphone signal cable structure is designed with a 5cm distance between the cylindrical component and the connector to ensure effective noise blocking and reduce the probability of friction with clothing, etc.

[0018] All parts not mentioned in this device are the same as or can be implemented using existing technology. This utility model uses a noise reduction component with a diameter three to five times that of the connecting wire. On the one hand, this ensures that the noise reduction component can effectively absorb and buffer the transmission of vibration, thereby reducing the transmission of friction noise to the headphones. On the other hand, it does not cause any abrupt changes to the signal line structure, ensuring the consistency and aesthetics of the signal line itself. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Example 1:

[0026] Reference Figure 1 and Figure 2 A headphone signal cable structure includes a connecting wire for conducting electrical signals and a connector at one end of the connecting wire. One end of the connector can be connected to a sound-generating device, such as a mobile phone or computer, and the other end can be connected to headphones for splitting. The structure also includes a noise-canceling component on the connecting wire, the diameter of which is three to five times the diameter of the connecting wire. This ensures that the noise-canceling component can effectively absorb and buffer the transmission of vibrations, thereby reducing friction noise transmitted to the headphones. Furthermore, it avoids abrupt changes to the signal cable structure, ensuring the consistency and aesthetics of the signal cable itself.

[0027] Specifically, the diameter of the noise reduction component is designed to be four times the diameter of the connecting wire, which ensures that the connecting wire will not undergo large deformation and that noise can be effectively blocked.

[0028] Here, the noise reduction component is designed as a counterweight, and the material of the counterweight is ferrous metal, specifically iron or steel.

[0029] The counterweight of the rotating body structure is preferably formed by splicing two semi-cylinders to cover the connecting line, thereby forming a cylindrical structure. The diameter of the counterweight is 8-12mm and the length is 18-22mm. Its overall diameter is four times the diameter of the connecting line.

[0030] In addition, a protective sleeve is included, which covers the counterweight to hide the metal counterweight. The two ends of the protective sleeve are attached to the connecting wire to form an integrated structure with the connecting wire. The material of the protective sleeve is preferably the same as the covering material of the connecting wire, such as rubber or other polyurethane elastomer materials, which can further reduce the protrusion of the counterweight and reduce vibration, improve the aesthetics of the entire signal cable and reduce the stethoscope effect.

[0031] Example 2:

[0032] Reference Figure 3 Similar to Embodiment 1, the noise reduction component is further designed as a cylindrical component spirally wrapped around the axis of the connecting line. The axis of the cylindrical component coincides with the axis of the connecting line, and both ends of the cylindrical component are integrally formed with the connecting line. That is, the cylindrical component is formed by wrapping around the connecting line multiple times. This not only ensures noise reduction but also further enhances the integrity of the signal line and gives the signal line a certain degree of extensibility, making the signal line more convenient to use.

[0033] Specifically, the cylindrical component has 4-6 spiral turns, which ensures that it will not rub against clothing or other materials, and also gives it a certain degree of elasticity to accommodate excess connecting wires.

[0034] In addition, the distance between the cylindrical part and the connector is 3-7cm, preferably 5cm, to ensure effective noise blocking and reduce the probability of friction with clothing, etc.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
