Problems solved by technology

[0002] The existing earphone cables have the following aspects that need to be improved: 1. The existing earphone cables are all directly extruded smooth strips without subsequent functional processing, and there is insufficient elastic deformation. The disadvantage of being easy to break, especially when used for earphone products that need to be stretched frequently, the earphone cable needs to meet tens of thousands of stretches or bends. If there is no corresponding elastic self-resetting structure, it will easily cause the earphone cable to break. Pulled or damaged; even if some headphone cables are very resistant to stretching, their self-resetting performance is still insufficient, which will still affect product quality
2. The design of the inner wires of the existing earphone cables is not reasonable. They are all simple insulating fillers covering single or multiple conductors, regardless of the main wire and the secondary wire, and do not pay attention to the reasonable layout, which affects the performance of the earphone wire.
[0003] When earphones (or other earphone products that require telescopic function) are retracted under the contracted state of the earphone cable, if the traditional spring-type telescopic earphone cable is used, it is easy to be unable to fit due to its large diameter. It is not conducive to product structure design; and the direct use of straight cables will easily cause the headphone cable to be broken or damaged because it does not have the telescopic function.
[0004] At the same time, when the traditional spring-type overlapping discharge and take-up is used, signal interference is likely to be caused between cables, which affects the high-fidelity effect of signal transmission

Embodiment 1

[0037] see figure 1 , 2 , the elastic memory self-resetting type earphone cable provided in this embodiment includes an earphone cord body 1, and a self-resetting structure 2 is provided on the earphone cord body 1, and the self-resetting structure 2 is a part of the earphone cord body 1. The length is bent and shaped into a wavy elastic structure (according to actual needs, it can be specifically: include two crests and one trough, or, two troughs and one crest, or more crests and troughs connected to each other), the wavy elastic structure There are more than two of them, which are evenly distributed on the earphone cord body 1 (that is, such a wave-shaped elastic structure is provided at intervals on the earphone cord body).

[0038] The headphone cable body 1 includes a sheath 3 and an inner wire 4, the inner wire 4 includes several single-layer conductor cores 5 and a double-layer conductor core 6, and these single-layer conductor cores 5 are distributed in double-layer ...

Embodiment 2

[0062] This embodiment is basically the same as Embodiment 1, except that step 2) specifically includes the following steps:

[0063] 2.1) First put the earphone cable body 1 into a fixed jig provided with a wave-shaped cavity; the wave-shaped cavity of the fixed jig includes two crests and one trough, or two troughs and one crest, or more connected peaks and valleys;

[0064] 2.2) After the jig is clamped, bake it at a temperature of 100°C and keep it for 40 minutes to shape it;

[0065] 2.3) After shaping, it is naturally cooled at room temperature for 50 minutes to form a wave-shaped elastic structure, and the elastic memory self-resetting earphone cable is obtained.

Embodiment 3

[0067] This embodiment is basically the same as Embodiment 1, 2, and its difference is that step 2) specifically includes the following steps:

[0068] 2.1) First, put the earphone cable body 1 into a fixing fixture provided with a wave-shaped shaping cavity; the wave-shaped shaping cavity of the fixing fixture includes two wave peaks and one wave valley, or, two wave valleys and one wave peak;

[0069] 2.2) After the jig is clamped, bake it at a temperature of 150°C and keep it for 20 minutes to shape it;

[0070] 2.3) After shaping, it is naturally cooled at room temperature for 70 minutes to form a wavy elastic structure, and the elastic memory self-resetting earphone cable is obtained.

Abstract

The invention discloses an elastic memory self-resetting earphone cable, which includes an earphone cord body, and is characterized in that the earphone cord body is provided with a self-resetting structure, and the self-resetting structure is bent by a part of the earphone cord body Shaped into a wave-shaped elastic structure, the wave-shaped elastic structure includes more than two, which are evenly distributed on the headphone cable body. The invention also discloses a method for preparing the elastic memory self-resetting earphone cable. In the present invention, the self-resetting structure is evenly distributed on the headphone cable body at intervals, so that it has the function of elastic memory self-resetting, and meets the needs of headphones (or some earphone products that often need to be stretched). It solves the shortcomings that the traditional spring-type telescopic cable cannot be installed and the straight cable does not have telescopic performance. The preparation method is fast and efficient, and can ensure the high-fidelity transmission quality of the product under the wave-shaped elastic structure.
