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 using the stiffness and elasticity of the earphone wire made of a spiral.

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, existing 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 the aforementioned non-portable electronic devices, which are not yet portable 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.

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 spiral 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 spiral wire 13 has a wire that transmits an electric signal at the center of the cross section, and is composed of a sheath surrounding the wire, and this sheath material is subjected to heat treatment to resist deformation due to external force. It is made to have stiffness and elasticity. Earphone according to the present invention has a structure that is convenient to carry and align by arranging the spiral 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 spiral 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 on the back of the mobile phone so that the earphone is not used when the earphone is not used. The alignment is not disturbed due to the rigidity, and when the earphone is used, when the user pulls the earphone head with a certain force, the alignment is naturally released as shown in FIG. 2 and is stretched to a suitable length for the user to use. It is. 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.

First, the wire is coated with the method described above, and then the spiral wire is formed in the same manner as the general telephone cord. Next, the spiral wire is hung on the protrusion of the aluminum or stainless jig having a plurality of protrusions at both ends, and the wire is hung on the opposite protrusion again and again. Fix it. 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 spiral wire having rigidity and elastic restoring force of the present invention is formed.

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 13a 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 13b 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 13c aligned 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.

As a more compact structure, the coiled wiring may be formed in a quadrangle as shown in FIG. 6. This rectangular coil wiring (13d) is designed to minimize the majority of the cell phone side of the rectangular structure, since the edge portion can be used more efficiently than the circular coil wire (13c) earphones having a sufficient length even a small area Can be configured.

Figure 7 is another embodiment formed by pressing the spiral earphone wire flat. In this case, the flat pressed form 13e can reduce the volume burden of the spiral wire and at the same time maintain the above advantages.

Hereinafter, still another embodiment of the present invention combined with the auxiliary tools for maintaining the shape of the earphone wire. These embodiments are structures that can enhance the rigidity of the wire.

FIG. 8 is a cross-sectional view illustrating a wire structure in which a steel wire 82 having rigid and elastic restoring force is insulated from the wires 83 for transmitting an electrical signal in parallel with the sheath of the earphone earphone wire 81. Such a structure can be used especially in the case where the above-mentioned rigidity and elastic force is insufficient only by the properties of the sheath itself 81, and can be constructed in a separate sheath as shown, or in the same sheath while being insulated from the wire 83. It can also be configured. In addition, since the steel wire 82 serves only a mechanical role, an elastic metal used for a metal spring or the like may be used. However, the steel wire 82 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.

When the steel wire is formed of 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 formed into a spiral and zigzag shape before encapsulation, and then the tension is temporarily internally The urethane sheath is formed with the wires and the external tension is again removed to form the intended two-dimensional structure.

FIG. 9 is a view showing still another embodiment of the present invention, for example, showing a case in which the shape maintaining means 91 is additionally provided in a bend forming a zigzag of the wire 13. In the present invention, it is essential to maintain the shape of the bent portion in order to have a zigzag wire alignment form, and thus, shape holding means 91 made of hard plastic or metal is added to the bent portion of the wire to enhance the rigidity of the portion.

The shape retaining means 91 may be coupled to all the bent portions as shown, or selectively coupled to only some of the bent portions, or may be coupled only 15 'to the portion close to the plug and earphone head where bending or shape retention is particularly important. In addition, the shape holding means 91 may be combined with the upper and lower parts made of solid, as shown in FIG. 10, and may be coated on the bent portion or the wire. It is also possible to solidify them after coating or pasting them. In addition, it is a matter of course that all the embodiments of the present invention can be used in combination with the shape maintaining means.

In this case, since the shape retaining means itself 91a thicker than the wire is a magnetic material, it may cause a stronger magnetic force locally.

In the case of the embodiment of Figures 11 and 12, it is also possible that the thin plate itself (110) attached to one side of the mobile phone is a magnetic material and the wire or shape holding means is made of a material that can be attached to the magnetic material. It is also possible for the microphone or earphone head material as well as the wire to be made of a magnetic material or the like by the method described above and attached to a corresponding predetermined portion on the back of the mobile phone. In addition, the internal steel wire 82 of the embodiment of FIG. 8 may be made of a magnetic material to utilize the magnetic force between the steel wire and the thin plate.

13 shows another embodiment of the present invention, in which case the earphone head 12 is attached to the connection plug 11 when not making a call so as to be arranged in a more orderly fashion. In general, the head of an earphone has a relatively large weight and volume compared to a wire. Therefore, the earphone head fixing part is formed in the connection plug to fix the same, and when the earphone is not used, the earphone head fixing part can be fixed to the earphone head fixing part, thereby maintaining a more compact structure.

14 and 15 show an embodiment having such a structure as viewed from the top, wherein the earphone head fixing part 151 is formed as a protrusion on a part of the earphone string, particularly near the plug 11, and thus the earphone head ( 12) is inserted and fixed. As an example, the head fixing unit 151 may be configured in any part of the earphone wire.

As another method for fixing the earphone head, a magnet having opposite polarity may be installed to be fixed to the head and the head fixing part, or a velcro may be attached to the contact part to be fixed.

FIG. 16 shows, for example, the case where the earphone plug 11 of the present invention is connected to the earphone jack 162 on the rear of the computer main body 160, and FIG. 17 is seen on the monitor 170 having the audio output in the front. As a schematic representation of a structure in which the inventive earphone 13 is integrally coupled, the earphone of the present invention can be always aligned neatly regardless of whether it is used in a situation where the earphone of the present invention is coupled to an electronic device, and thus useful for non-portable electronic devices.
