Abstract
The utility model discloses a three-color spiral headphone line. The headphone line comprises a plurality of enameled wire groups which are wrapped by insulating layers with different colors and coating layers arranged outside the enameled wire groups. The each coating layer is uniformly wound by three kinds of insulating materials with the different colors as a spiral shape so as to form a cylinder. According to the utility model, the enameled wire is made into the three-color spiral cylindrical headphone line. A stereoscopic effect is strong in appearance and color separation is clear. A visual effect is good, which is convenient for a user to use separately. And a feel of the line is good. Besides, the line insulating material is a thermoplastic elastomer (TPE) with high reliability. A conductor is the enameled wire so that an audio signal is transmitted as a high fidelity mode.
Description
Technical field
The utility model relates to wire, especially relates to a kind of earphone cord for transmit audio signals.
Background technology
Along with the development of science and technology, various audiovisual electronic equipments more and more are subject to people's favor.At present, be used for the earphone cord of transmit audio signals on market, the shape color is single, and major part is the line of the of the same colour of flat or two looks.As shown in Figure 1, flat two look earphone cords, this line comprise is located at the enamelled wire between coated 1 and green lower coated 2 on black, and versicolor insulating barrier is arranged outside enamelled wire, such as, blue insulating barrier, green insulating barrier, red insulating barrier or coated blue red insulating barrier.This conventional earphone wire is not easy to user's identification, and impact is used.In addition, outward appearance is common, design is novel not.
The utility model content
For solving the problems of the technologies described above, the utility model provides three look spirality earphone cords of a kind of user's of being convenient to identification, novelty attractive in appearance.
A kind of three look spirality earphone cords that the utility model provides, it comprises the many outer enamelled wire groups that the shades of colour insulating barrier is arranged, and is located at the outer coating of this enamelled wire group.Described coating curls up into cylinder in the shape of a spiral equably by the insulating material of three kinds of different colours.
More excellent, the outer field insulation material of described enamelled wire can be thermoplastic elastomer (TPE) (TPE---Thermoplastic Elastomer).
More excellent, the insulating material of described the first color is white plastic, and the insulating material of the second color is black plastic, and the insulating material of the third color is red plastic.
The utility model is made three looks spiral cylindrical earphone cord with enamelled wire, and outward appearance seems that third dimension is strong, and the color boundary is clear, and good visual effect is convenient to the user and is distinguished use, and feel might as well.In addition, the exhausted material of line is the TPE of high-reliability, and conductor is enamelled wire, can make the audio signal high fidelity transmit.
Description of drawings
Below in conjunction with embodiment and accompanying drawing, the utility model is elaborated, wherein:
Fig. 1 is the schematic cross-section of existing flat two look earphone cords;
Fig. 2 is the schematic diagram of the utility model preferred embodiment;
Fig. 3 is the cross section enlarged diagram of the utility model preferred embodiment.
Embodiment
Fig. 2, Fig. 3 show the basic structure of the utility model preferred embodiment.A kind of three look spirality earphone cords that the utility model provides, it comprises the many outer enamelled wire groups 7 that the shades of colour insulating barrier is arranged, and is located at 7 groups of outer coatings of this enamelled wire.This coating curls up into cylinder in the shape of a spiral equably by the insulating material of three kinds of different colours.The insulating material of the first color is white plastic 4, and the insulating material of the second color is black plastic 5, and the insulating material of the third color is red plastic 6.Three kinds of plastic cement not color can also choose as required.During making, white plastic 4 can pass through the main frame extrusion, and black, red dichromatism plastic cement 5,6 can pass through to annotate the extrusion of bar machine, and form the helical form wire rod by rotary die.The outer field insulation material of enamelled wire can be thermoplastic elastomer (TPE) (TPE).
The utility model is made three looks spiral cylindrical earphone cord with enamelled wire, and outward appearance seems that third dimension is strong, and the color boundary is clear, and good visual effect is convenient to the user and is distinguished use, and feel might as well.In addition, the exhausted material of line is the TPE of high-reliability, and conductor is enamelled wire, can make the audio signal high fidelity transmit.
The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
