The present invention relates to an earphone for an electronic device, and more particularly, to an earphone for an electronic device in which the earphone is automatically aligned on one surface of the electronic device by using the rigidity and elasticity of the earphone wire.

A portable device such as a Walkman, a mobile phone, an MP3 player, or a PDA can be used by connecting an earphone to the voice signal input / output port. As these earphones are becoming more common these days, many users are using them, and in recent years, the trend of banning or picking up mobile phones by hand while driving is being strengthened around the world. It is becoming established.

However, conventional earphones for mobile devices are composed of long lines of wires or cords (hereinafter referred to as wires), so it is difficult to keep them neatly organized when connected to mobile devices. Therefore, in general, the earphones are separated from the mobile device in a separate state, and are often temporarily connected only when used. However, this method has the inconvenience of having to store the earphone separately and the inconvenience of having to remove the earphone to the mobile device every time.

This problem is not limited to mobile devices. Yosai often uses earphones for DVD players, computers, even monitors with separate speakers, audio systems, TVs, etc. These earphones are also stored separately from the system. This is because it is very difficult to align the earphones with the system when not in use.

Several solutions have been developed to enable the use of earphones connected to electrical equipment at all times.

As one of the existing solutions, there is a method of attaching a wire case to the back of a mobile phone and winding the wire with a spring (Application No. 10-2000-005114). However, such a configuration includes an additional earphone wire holder. Accordingly, there is a disadvantage in that the volume of the entire portable device is increased and the manufacturing cost is also increased, but it is not generally widely used. In addition, these solutions are often limited to mobile devices and are not extended to non-mobile electronic devices.

The present invention is to solve the above-mentioned problems, the earphone is connected to the electronic device, the wire is automatically aligned, there is no twist or tangling at the same time the volume increase is not large at the same time can be used in the electronic device earphone The purpose is to provide a structure.

Another object of the present invention is to provide a structure of an earphone for an electronic device, in which the entire wire is automatically aligned with one surface of the electronic device by the elastic force and the restoring force of the earphone wire itself.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

For reference, the following embodiments are described with reference to a mobile phone as an example, but it is as described above that the earphone of the present invention can be applied to any electronic device that can use the earphone in addition to the mobile phone.

1 is a view showing a basic embodiment of the present invention. The earphone of this embodiment has a structure in which a connection plug 11 inserted into a voice signal input / output terminal 10 of a mobile phone and an earphone head 12 and a wire 13 electrically connecting the two are integrated. In addition, in the case of an earphone used for a mobile phone or the like that needs to transmit a user's voice, the small microphone 14 may be added at an appropriate position in the middle of the wire.

The wire 13 has a wire that transmits an electrical signal at the center of the cross section, and is composed of a sheath surrounding the wire, and the sheath material has a property of resisting deformation due to external force by applying heat treatment. It is designed to have stiffness and elastic resilience. Earphone according to the present invention has a structure that is convenient to carry and align by arranging the wire having the sheath of the material in a two-dimensional planar structure to occupy a minimum area and volume.

In the earphone of FIG. 1, the wire 13 having the sheath of the material is formed in a two-dimensional shape as shown in a zigzag, for example, to be aligned with the back of the mobile phone. Due to the rigidity, the alignment is not disturbed, and when using the earphone, when the user pulls the earphone head with a certain force, the alignment is naturally loosened as shown in FIG. 2 and is stretched to an appropriate length for the user to use. have. In addition, when the user puts the earphone head off the ear after the end of the call is configured to be aligned and restored to the state of Figure 1 again by the above-mentioned elastic restoring force.

Therefore, the earphone of the present invention is accommodated by the rigidity and elastic force of the wire, and as in the prior art, a separate structure that is required for the storage of the earphone wire is unnecessary. For example, a thermosetting material of TPU (Thermo Plastic Urethane) type may be used as the wire coating material.

As an example of making the above-described wire structure, the following materials and methods can be used.

As the wire coating material of the present invention, for example, urethane for wire coating such as K-185 PNH and K-285 PCH of Kolon can be used. The hardness of these materials is maintained at about 85a. If such materials are processed by high temperature extrusion or the like, the wire coating of the present invention can be formed.

An example of how to make a zigzag shape of a wire is as follows.

Once the wire has been coated with the method described above, the wires are applied to the protrusions of aluminum or stainless jigs having a plurality of protrusions at both ends, and then wires to the opposite protrusions. To fix the wire in the shape of zig-zag. When the wire is fixed in a two-dimensional zigzag form, the wire is heat-treated in a fixed state. In the case of the material, when heated to about 10 to 30 minutes at about 160-180 degrees Celsius, and the temperature is lowered, a wire having rigidity and elastic restoring force of the present invention is formed.

The length of the wire is determined by the number of zigzag. When 30 zigzags of 4 cm are overlapped, the total length of the wire is 120 cm, which is sufficient for use. When the thickness of the wire sheath is 1.5mm, the overall width of the zigzag is about 5cm, so it can be made small enough to be attached to the back of the mobile phone.

3 to 7 show some embodiments of the earphones of the present invention having the wire coating of the above-described material arranged in the rear of the mobile phone. For convenience, the microphone is omitted in the drawing.

When the cell phone is used in a pocket or the like, since the earphone wire is conveniently stretched upward of the cell phone, the zigzag shape 13 of the wire may be arranged in the transverse direction of the cell phone as shown in FIG. 3.

FIG. 4 shows another zigzag case 13 having a curved shape rather than a straight line, and shows that various designs are possible in consideration of functional convenience and aesthetics of the earphone wire being released.

5 shows the earphone wiring 13 arranged in the form of concentric coils rather than zigzag. This structure is configured such that two wires are wound in a two-dimensional coil form based on the center of the earphone string, and the connection plug 11 and the head 12 of the earphone are arranged at the edges. In this case, pulling the earphone head can keep the shape neat even when the string is stretched.

The method of making this structure is to overlap the middle part of the earphone wire and fix it at the center of the jig, and to wind the two strands simultaneously in concentric circles so that the head and the connecting plug are located at the outermost part of the wire coil. Then, the heat treatment in the manner described above is the same.

As a more compact structure, the coiled wiring may be formed in a quadrangle as shown in FIG. 6. The rectangular coil wiring 13 is designed by deducting that most mobile phone surfaces have a rectangular structure, and since the edge portion can be used more efficiently than a circular coil wire, an earphone having a sufficient length can be constructed with a small area. Can be.

Such a structure may be configured in a separate sheath as shown, or in the same sheath while being insulated from the wire 91. In addition, since the steel wire 92 performs only a mechanical role, an elastic metal used for a metal spring or the like may be used. However, the steel wire 92 is not necessarily a metal material, and may be any material capable of performing the same function. For example, highly elastic plastics and linear rubbers are examples.

In the case of forming the steel wire with the elastic metal material in the above structure, since the elastic metal is generally formed at a higher temperature than the polymer of the coating, the steel wire is zigzag in advance before the sealing, and then the tension is temporarily applied to the inner wire and Together, the urethane coating is formed and the external tension is again removed to form the intended two-dimensional structure.
