Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crosstalk preventing device for preventing crosstalk in an earphone cord used in a small acoustic device.

[0002]

2. Description of the Related Art Conventionally, small-sized audio equipment such as a headphone stereo has been faced with a problem of cross-connection of earphone cords.
That is, if the earphone cord is left unused when not in use, it will cause crosstalk, and it will be troublesome to loosen it when reused. For this reason, some anti-crossing devices have been invented. For example: (1) Hook belt 1 attached to earphone cord of FIG.
No. 1 rounded the earphone cord 2 and partially fixed it with a hooking belt 11 to prevent crosstalk. (2) The storage storage bag 12 shown in FIG.
3, one end is connected, the other end is openable and closable, and the end on the open and close side is freely lockable. Therefore, first, the small-sized audio equipment 15 is stored in the storage bag 12, the earphone cord 2 is wrapped around the outer periphery of the storage bag 12, avoiding the opening / closing band 13, and finally the earphone cord is locked by the opening / closing band 13. . (3) The small acoustic device 15 in FIG. 19 is loaded with the rotary winder 14 for the earphone cord, and rotates to accommodate the earphone cord 2.

[0003]

However, the relatively widespread crosstalk preventers described above also have problems. (1) The hooking belt is cumbersome to attach and detach the belt, and is not used as an earphone cord crossing prevention device today. (2) It is troublesome to always carry a storage bag with an opening / closing band. (3) The rotary winding device has a limitation that it cannot be used for all small acoustic devices in terms of cost and structure. Under such circumstances, an object of the present invention is to provide a simple, convenient, and practical cross-talk preventing device.

[0004]

In order to achieve the above object,
The following crossing prevention device is provided. That is, a wire 1 having an appropriate length and hardness is attached to an appropriate portion of an earphone cord 2 and coated with a coating material 3 such as insulating vinyl chloride for protection. Thus, the wire 1 and the earphone cord 2 are integrated. When the earphone cord 2 is rolled into an annular shape when not in use, a part of the annular portion or the annular central portion is wound and fixed by the wire 1 integrally attached to the earphone cord 2. It is a cord crossing prevention device.

Further, one end of a hook-and-loop fastener 4A4B composed of two pieces of male and female is joined in a hinge-like manner by means of sewing, gluing, or a bridging member 5, and the other end is freely openable and closable. An adhesive portion b using an adhesive is provided on the back surface of one piece or, when the construction material 5 is interposed, on the back surface of the construction material 5 to make it possible to adhere to an appropriate place on the outer wall of the small acoustic device 15. When the earphone cord 2 is wound around the small acoustic device 15 during use, the earphones 18A18B
An earphone cord cross-talk preventing device characterized in that the forked cord 17A17B connected to the earphone cord or the whole wound earphone cord 2 is bundled and fixed.

In this case, it is possible to provide a reinforcing plate (6) made of a thin plate of metal or resin on the back surface of the hook-and-loop fastener (4A) serving as the opening / closing lid.

Further, an anti-slip body (7) made of an elastic material such as sponge or rubber is provided on both surfaces or a part of one of the occlusal surfaces (C) of the surface fasteners (4A) and (4B). Is possible.

In the case where one end of the hook-and-loop fastener (4A) (4B) is joined in a hinge shape with an erect member (5),

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on examples with reference to the drawings. FIG. 1 shows a first embodiment of the present invention.
2 shows an earphone cord crosstalk prevention device 20A of the embodiment.
That is, a wire 1 of an appropriate length and hardness is attached to an appropriate portion of an earphone cord 2 and covered with a coating material 3 such as insulating vinyl chloride for protection. According to the results of trial use, in this case, the appropriate length means that there are two ways of using the cross-talk preventing device 20A, and the appropriate length differs depending on the usage. In the first use, FIG.
As shown in the figure, when the earphone cord 2 is
In this case, one wire is fixed to a part of the ring by winding it two or three times. In this case, it is sufficient if the length is a few centimeters. In the second usage, as shown in FIG. 3, when the earphone cord 2 is rolled into an annular shape, the wire 1 portion is used to fix the annular central portion three to four times and fixed. As a result, about 7 to 10 cm was an appropriate length. Also, the appropriate hardness of the wire 1 may be sufficient as long as the wire 1 is used to fix the earphone cord 2 that is rolled into an annular shape as described above. In other words, if it is too soft, it cannot be fixed when it is wound, so it is inappropriate. If it is too hard, it is difficult to handle. The appropriate location A of the earphone cord 2 to which the wire 1 is attached actually refers to a side of the earphone jack 19. The wire 1 maintains a certain shape, and as a result of trial, it has been found that the wire 1 is troublesome and obstructive at other places. FIG. 4 shows a cross-sectional view in which the wire 1 is attached to the earphone cord 2 and covered with a coating material 3 such as vinyl chloride. In this case, the wire 1 is connected to the earphone cord 2,
It is better to fix with an adhesive or the like. As a result of the trial, it was found that if the wire was not fixed, the end of the wire 1 would move, leaving a possibility of breaking through the coating material, which was not good. FIG. 5 shows a case where instead of coating with vinyl chloride or the like, a heat-shrinkable pipe 16 that shrinks by natural cooling after heating is fitted and coated, and the same effect can be obtained in this case. In this case, both ends of the heat-shrinkable pipe 16 are preferably slightly longer than the wire 1. FIG. 6 shows that the wire 1 is directly attached to the lead wire 9 of the earphone cord 2 instead of attaching the wire 1 to the earphone cord 2, and the same purpose can be achieved. Hereinafter, the use of the present invention will be described in detail with reference to FIGS. FIG. 2 illustrates a first use of the earphone cord crosstalk prevention device 20A according to the first embodiment of the present invention. The present invention can be used to prevent crosstalk as follows. That is, the earphone cord 2 removed from the small-sized audio equipment 15 is rounded in an annular shape, and a part of the annular shape is wound and fixed at the portion where the wire 1 is applied. In this way, the rounded earphone cord 2 will not be cross-wired. FIG.
7 illustrates a second use. That is, the earphone cord 2 removed from the small acoustic device 15 is rounded in an annular shape,
The whole of the annular central portion is wound and fixed at the portion where the wire 1 is applied.
In this way, the rounded earphone cord 2 will not be cross-wired.

FIG. 7 shows an earphone cord cross-talk preventing device 20B according to a second embodiment of the present invention. That is, one end of the hook-and-loop fastener 4A4B composed of two male and female pieces is sutured,
Glue and join in a hinge shape. In this case, one end of the hook-and-loop fastener 4 </ b> A <b> 4 </ b> B may be hingedly connected via the bridging member 5. By doing so, the other end of the hook-and-loop fastener 4A4B can be opened and closed freely.
Alternatively, it is possible to bundle and hold the entire earphone cord 2. Further, in recent years, as one of new surface fasteners, one provided with both males (so-called hooks) and females (so-called loops) on one occlusal surface has been developed. In this case, the hook-and-loop fastener only needs to be folded in two. On the other hand, an adhesive is applied to the back surface of one of the hook-and-loop fasteners 4A4B, or to the back surface of the erection member 5 when the erection member 5 is interposed, and an adhesive portion B is provided by applying a release paper. In this case, a commercially available double-sided tape with a strong adhesive may be attached. By this bonding portion b, the small acoustic equipment 15
Can be attached at appropriate places. Here, the term “appropriate location” means a small audio equipment 15 depending on each manufacturer or product.
Since the size of and the length of the earphone cord 2 are different,
This means that where the crosstalk prevention device 20B for winding and fixing the earphone cord 2 is to be attached, the appropriate location is different. In this case, the width is required to be at least 5 mm with respect to the longitudinal direction of the hook-and-loop fastener.
~ 2 cm is easier to handle. If the width is small, the holding force is lost and it is not suitable. As for the length in the longitudinal direction, there are two ways of using the crosstalk prevention tool 21B, and the two methods differ depending on the usage. FIG. 8 shows the first usage. First, the earphone cord 2 is wound around the small-sized audio equipment 15, and after the winding is completed, the forked cord 17A17B is clamped and fixed by the crosstalk prevention device 20B. In this case, a length of the hook-and-loop fastener in the longitudinal direction of 1 cm is sufficient, and a length longer than that is not necessary. That is, in this case, it was found that even if the dimensions of the hook-and-loop fasteners 4A4B were reduced, the purpose of preventing cross-linking could be sufficiently achieved. FIG. 9 shows the second usage. When the earphone cord 2 is wound around the small audio equipment 15, the earphone cords 2 are all bundled and held and fixed by the crosstalk prevention device 20B.
Centimeter lengths are practically easy to handle. If it is less than 2 cm, it is difficult to hold all the earphone cords 2, and it may be considered that a length of 4 cm or more is not necessarily required. In addition, there is no problem in holding the hook-and-loop fastener in a rectangular shape or a rectangular shape. Further, the material of the erection material 5 may be considered to be particularly irrelevant, such as cloth, metal, resin, or the like, as long as the material does not hinder bending at opening and closing. Further, there are so-called male and female hook-and-loop fasteners, and it is apparent that there is no need to specify which one is the open / close lid and which is to be adhered to the small audio equipment 15 in actual trial use. Hereinafter, FIG.
9, two types of usage of the crosstalk prevention device 20B of the present invention will be described in more detail. First, as shown in FIG. 8, first, the crosstalk prevention device 20B of the present invention is bonded and fixed to an appropriate portion of the small acoustic device 15 via the bonding portion B, and then the earphone cord 2 is After winding around the outer periphery of the device 15 and finishing the winding, the forked cord 17A17B is clamped and fixed by the hook-and-loop fastener 4A4B. By doing so, the earphone cord 2 wrapped around the small acoustic device 15 is fixed,
There is no crosstalk. A second use is that the length in the longitudinal direction is sufficient, as shown in FIG.
This is a case where a hook-and-loop fastener having a length of centimeters is used, and all the earphone cords 2 wound around the small acoustic device 15 are bundled and fixed. In this case, the small audio equipment 1
The earphone cord 2 wrapped around 5 is fixed, and no crosstalk occurs.

[0011] As a result of various trials of the cross-talk prevention device using the surface fastener 4A4B, one problem was found with respect to a general surface fastener. That is, the purpose of the hook-and-loop fastener is not to hold the object, but to focus on the engaging force, that is, the so-called shear strength (tensile shearing force) and peel strength (peeling strength), which is required by this cross-link prevention device. Nipping strength is not of interest. Therefore, when a commercially available hook-and-loop fastener is used, it has been found that even if the earphone cord is pinched, the earphone cord is not always securely fixed and slips and loosens. Looseness does not cause crosstalk, but is undesirable. Therefore, as a countermeasure, the following two methods were obtained. The first method uses what is sold by the hook and loop maker under the trade name Multilock. It turns out that the earphone cord is securely held and fixed. The second method is to use other surface fasteners. In this case, it is better to reinforce the holding force of the surface fastener. Hereinafter, in FIGS.
Various methods for reinforcing the holding force of the hook-and-loop fastener will be described. FIG. 10 shows a structure in which a reinforcing plate 6 made of a metal or resin thin plate is attached between the back surface of a hook-and-loop fastener 4 </ b> A serving as an opening / closing lid and a bridging member 5. Thus, it has been found that the pinched earphone cord 2 or the forked cord 17A17B is strongly fixed. The hook-and-loop fastener piece 5 </ b> B bonded to the small acoustic device 15 may not have the reinforcing plate 6.
Needless to say, the small acoustic device 15 plays the role of the reinforcing plate 6. The reinforcing plate 6 is a hook-and-loop fastener 4A.
If the size is slightly smaller than 4B, the size does not protrude.

FIG. 11 shows an embodiment in which the slip fastener 7 is provided on the hook-and-loop fastener 4A4B. That is, hook-and-loop fastener 4A
When one end of 4B is hingedly connected with the mounting member 5, a part of the surface fastener 4A4B is cut out, and the anti-slip body 7 made of an elastic material such as sponge or rubber of the same size is formed in the cut-out portion. It is provided through.
The anti-slip body 7 may be made of any material having a high coefficient of friction other than sponge or rubber. When the anti-slip body 7 is provided, one anti-slip body 7 may be provided over two pieces of the hook-and-loop fastener 4A4B, or two anti-slip bodies 7 may be provided separately from the hook-and-loop fastener 4A4B. Good. Also in this case, if the reinforcing plate 6 is provided between the hook-and-loop fastener 4A serving as the opening / closing lid and the erection material 5, there is an effect of holding up. FIG. 12 shows the thickness of the anti-slip body 7. That is, when the anti-slip body 7 is provided slightly thicker than the occlusal surface A and B, the earphone cord 2 or the bifurcated cord 17A17B can be more strongly held.

FIG. 13 shows an embodiment in which the anti-slip body 7 is used widely in the longitudinal direction. That is, an anti-slip body 7 made of sponge or rubber is arranged between the two pieces of hook-and-loop fasteners 4A4B, and is hinged via the bridging member 5. The purpose of this is to lengthen the contact portion with the earphone cord 2 or the bifurcated cord 17A17B, thereby increasing the force for holding and fixing. When the anti-slip body 7 is provided, one anti-slip body 7 may be provided over two hook-and-loop fasteners 4A4B, or two anti-slip bodies 7 may be provided on each of the hook-and-loop fasteners 4A4B. Also in this case, if the reinforcing plate 6 is provided between the hook-and-loop fastener 4A serving as the opening / closing lid and the erection material 5, there is an effect of holding up.

FIG. 14 shows another embodiment of the anti-slip body 7. That is, on both sides of the occlusal surface A A
The anti-slip body 7 is formed by welding an elastic material such as rubber or resin in a gel state. It is advantageous that the anti-slip body 7 is slightly thicker than the occlusal surfaces A and B in order to hold it. This anti-slip body 7 is not an occlusal surface A A
Any one of them may be provided on one side, but providing on both sides provides a higher holding effect. Also in this case, if the reinforcing plate 6 is provided between the hook-and-loop fastener piece 4A serving as the opening / closing lid and the erection material 5, the holding effect is obtained.

FIG. 15 shows a narrowing groove in which one end of the hook-and-loop fastener 4A4B is hingedly connected with the bridging member 5 to provide a slight gap between the two hook-and-loop fasteners 4A4B and to insert and hold the earphone cord 2. 8 is provided. Since the purpose of the holding groove 8 is to fit and hold the forked cord 17A17B, the gap is preferably about 2 to 3 mm. FIG. 16 shows a configuration in which auxiliary holding pieces 10 </ b> A and 10 </ b> B such as sponges are arranged on both sides of the holding groove 8.
In this way, the holding force can be reinforced. Also in this case, if the reinforcing plate 6 is provided on the hook-and-loop fastener 4A serving as an opening / closing lid, there is a holding effect.

[0016]

[Effects of the Invention] It has been scattered that one person removes the earphone cord when not in use from a small acoustic device and rounds it, and another person wraps it around the small acoustic device. Needless to say, this alone would cause crosstalk. The present invention is a simple, convenient, and practical cross-talk prevention device for preventing the rounded or wound earphone cord from cross-talk. First, the wire crossing prevention device 20A utilizing wire according to claim 1 is excellent in the following points. That is, after the earphone cord 2 is rounded in an annular shape, by winding a wire 1 integrated with the earphone cord 2 around a part or annular center of the annular shape, the rounded earphone cord 2 can be easily fixed. Extremely simple, convenient and practical. In addition, compared to the above-mentioned hooking belt 11, the earphone cord 2 and the wire 1 are integrally mounted, so that they do not interfere with the use. On the other hand, the crossover prevention device 20B utilizing the surface fastener according to claims 2 to 5 is also excellent in the following points. That is, the earphone cord 2 is connected to the small acoustic device 15.
When the end of the earphone cord 2 is completely wound, the earphone cord 2 is fixed simply by bundling a part or the whole thereof and holding the earphone cord 2 with a hook-and-loop fastener. It takes no effort or time. Further, the size of the preventive device 20B does not cause any trouble or inconvenience in using the small acoustic device 15.
