Detailed ways

Below, in conjunction with embodiment, the utility model is further described in detail. the

FIG. 1 is a schematic diagram of a stereo earphone according to an embodiment of the present invention. the

As shown in Figure 1, the stereo earphone of present embodiment, it comprises: left and right pair of stereo earphone main body 1, earplug 2, the plug 7 that is used to link music player etc., has link left and right pair of stereo earphone main body 1 and plug 7 The first earphone wire 31 and the earphone wire 3 of the two branch wires of the second earphone wire, and the slidable noise attenuation mechanism 6, wherein the earplug 2 is arranged at the front end of the sound guide tube, and the sound guide tube is used to put the built-in The sound of the speaker device of the earphone body 1 is effectively guided to the external auditory canal of the ear; the slidable noise attenuation mechanism 6 has jointable or detachable connecting parts arranged on the two branch lines of the earphone cord 3 . the

As shown in Figure 1, on the position where the earphone wire 3 on the side of the plug 7 is divided into two branch lines, the first earphone wire 31 and the second earphone wire 32, an earphone wire fork 4 is provided, and the earphone wire fork 4 An earphone cord slide button 5 is arranged between the noise attenuation mechanism 6 . the

In addition, FIG. 2 shows the state of the stereo earphone of the embodiment of the present invention when it is worn, and FIG. 3 shows the state of the stereo earphone of the embodiment of the present invention before it is worn on the ear. the

In addition, Fig. 4 is a detailed illustration of the noise attenuation mechanism 6 arranged on the two branch lines of the earphone line 3, wherein Fig. 4 (a) is an external view of the noise attenuation mechanism 6 in the connected state, and Fig. 4 (b) It is a side view of the noise attenuation mechanism 6 . the

Next, the stereo earphone of the present invention will be described. the

First, the stereo earphone has the earphone main body 1 for the right ear and the earphone for the left ear, so that different sounds can be played on the left and right. In addition, the earphone main body 1 is formed of resin, metal, ceramics, etc., and has an electroacoustic transducer that drives a vibration plate according to an audio signal, that is, a drive unit (or a speaker device). the

In addition, in the plug-in stereo earphone, the sound guide tube on which the earplug 2 is installed protrudes from the drive unit in a convex shape. When the earphone main body 1 is worn on the ear, the elastic earplug 2 can be firmly inserted into the external auditory canal of the ear, and the earplug 2 can be firmly inserted into the external auditory canal of the ear through the elasticity. deformation, so that most of the earplugs 2 are closely attached to the inner surface of the external auditory canal, improving the sealing performance of the external auditory canal between the sound guide tube and the tympanic membrane. Therefore, there is little leakage of the sound generated from the drive unit in the earphone body 1 during transmission to the eardrum, so that low-frequency to high-frequency sounds can be transmitted stably with little sound loss. the

Also, in the case of stereo earphones, since there is no headband, etc., which are required to be worn on the head in a headset, when the earphone main body 1 is worn on the ear, the friction or vibration received by the earphone wire 3 will pass through the earphone. The main body 1 is transmitted directly to the ear holding the earphone main body 1, and becomes an unpleasant noise. the

Furthermore, in the plug-in type stereo earphone, since the sealing performance between the earphone main body 1 and the external auditory canal is improved by the elastic earplug 2, louder noise can be heard. the

In particular, when the earphone main body 1 is worn on the ear, the loud noise generated by the earphone cord is caused by rubbing the earphone cord 3 against clothes, face, etc., or by hanging the earphone cord 3 loosely on the hand or luggage. 3 is generated when it is tightened, and it is heard as unexpected loud noise, so it is very unpleasant and hinders the viewing and listening of comfortable music. the

In view of the above-mentioned problems, in order to reduce the vibration transmitted to the earphone main body 1 significantly before being transmitted to the earphone main body 1, it is necessary to make the earphone wire 3 from the vibration generating part to the earphone main body 1 when the earphone main body 1 is worn on the ear. The parts are in a firm and stable state so that no loud noise can be heard even when the friction noise as described above is generated or the earphone cord 3 is stretched. the

Therefore, on the two branch lines of the earphone cord 3, that is, the first earphone cord 31 and the second earphone cord 32 between the earphone cord fork 4 and the earphone main body 1, a noise attenuation device having a connecting member that can be joined or separated is provided. Mechanism 6, as shown in Figure 2, when the earphone main body 1 is worn on the ear, if the connecting portion of the noise attenuation mechanism 6 is connected behind the neck of the wearer of the earphone main body 1, because the earphone wire 3 on the plug 7 side Or the weight of the player, the noise attenuation mechanism appears to be in a state of being tightly attached to the back of the neck, thereby keeping a part of the headphone cable 3 stable. the

As mentioned above, since the first earphone cord 31 and the second earphone cord 32 connecting the plug 7 and the earphone main body 1 can be stably maintained at a position very close to the ear from the earphone main body 1 wearer's neck, the Reduce the noise caused by the vibration that is likely to occur in front of the wearer's body of the earphone main body 3 due to friction between the earphone cord 3 and clothes, or loose earphone cord 3 hanging on the hand. the

In addition, here, since the connecting member of the noise attenuation mechanism 6 can be joined or separated, as shown in FIG. . the

In this noise attenuation mechanism 6, the first connecting member 61 and the second connecting member 62 are not integrally formed, but are made into a jointable or separable structure, thus, even if the headphone cord 3 of the two branch lines is not long enough Therefore, the headphone wearer can arrange the mechanism behind the head and neck while the hairstyle is not damaged or even wearing a hat, so a good effect can be obtained. the

In addition, in Fig. 2, when the stereo earphone is worn, the position of the noise attenuation mechanism 6 is close to the earphone main body 1 side of the two branch lines of the earphone line 3, and the earphone line 3 between the earphone main body 1 and the noise attenuation mechanism 6 is preferably not too far Relaxed state. However, as shown in FIG. 3 , the noise attenuation mechanism 6 can also be placed approximately in the middle of the two branch lines of the earphone line 3 before the stereo earphone is worn. If it is in this position, the noise attenuation mechanism 6 can be connected behind the neck. At this time, the situation that the earphone wire 3 is tightened and the worn earphone main body 1 falls off hardly occurs. the

As mentioned above, since the optimal position of the noise attenuation mechanism 6 is different before and after it is arranged on the back of the neck, by making the noise attenuation mechanism 6 slideable at the two branch line parts of the earphone cord 3, it is possible to make the noise attenuation mechanism 6 at the back of the neck The connection of the noise attenuation mechanism 6 becomes simple and easy, and the inconvenience when the noise attenuation mechanism 6 is connected at the back of the neck can be reduced. the

At this time, in order to improve the slidability of the noise attenuation mechanism 6, it is preferable that the diameters of the earphone wire penetration holes of the first connecting member 61 and the second connecting member 62 of the noise attenuating mechanism 6 be larger than the diameters of the first earphone cord 31 and the second earphone cord. The thickness of 32 is at least 0.3mm larger. the

Also, as shown in Figure 4 (b), the connecting portion 1011 of the second connecting member 101 of the noise attenuation mechanism 6 has a convex shape, and the connecting portion 1001 of the first connecting member 100 has an O-shaped annular shape, as shown in Figure 4 ( As shown in a), when the noise attenuation mechanism 6 is in the connected state, the first connecting member is configured to be movable in the rotational direction around the convex second connecting member. the

Due to the above-mentioned movable mechanism, in the state where the noise attenuation mechanism 6 is connected behind the neck, even if the wearer of the earphone body 1 twists to the left or right, the effect that the earphone body 1 is not easy to fall off can be obtained. the

This is because, as shown in FIG. 5, when the earphone wearer faces the front, the distances from the noise attenuation mechanism 6 to the left and right ears are approximately the same, but as shown in FIG. The distance between the noise attenuation mechanism 6 and the left and right ears changes, that is, the distance between the noise attenuation mechanism 6 and the left and right earphone bodies 1 also becomes left-right asymmetrical, and the earphone on the side where the distance between the noise attenuation mechanism 6 and the earphone body 1 becomes longer The wire is pulled toward the headphone body 1 side, and the headphone wire on the other side is pulled back from the headphone body 1 side to the noise attenuation mechanism 6 side. the

When the earphone wire 3 enters and exits in the earphone wire through hole of the noise attenuation mechanism 6, since the connecting parts of the noise attenuation mechanism 6 can move, so each noise attenuation mechanism 6 can change its position or direction, so that the earphone wire of the noise attenuation mechanism 6 The through hole turns to the direction in which the earphone wire 3 enters and exits. the

Therefore, when the wearer of the earphone main body 1 twists to the left or the right, even if the earphone cord 3 is pulled toward the earphone main body 1 side, since the connecting member of the noise attenuation mechanism 6 rotates around the convex part, the earphone cord 3 can be smoothly rotated. It can reduce the phenomenon that the earphone main body 1 falls off from the ear due to the earphone wire 3 being stuck. the

Next, discuss the optimal length L of the two branches of the earphone cord 3 from the fork 4 of the earphone cord to the earphone main body 1 . the

Usually, the length of the two branch wires of the earphone cord 3 of the stereo earphone is mostly 35 cm to 40 cm. the

However, when the noise attenuation mechanism 6 is connected behind the neck when the earphone is used like the stereo earphone of the present embodiment, since the earphone wire 3 reaches the chest from the ear through the back of the neck, the distance from the ear to the chest is different from that through the back of the neck. The distance difference when reaching the chest is about 10cm. Therefore, it needs to be longer than the length of the two branch lines of the general headphone cable, and the minimum required length is 45cm to 50cm. the

In addition, in order to connect the noise attenuation mechanism 6 at the back of the neck, the noise attenuation mechanism 6 located in front of the body should be pinched first with fingers. 6 delivery, therefore, the headphone cable should have at least a length that can deliver the noise attenuation mechanism 6 near the shoulders of the headphone wearer. the

Generally speaking, a man with a height of about 170cm has a shoulder width of about 40cm, and, depending on the degree of bending of the arm, the noise attenuation mechanism 6 must pass through a place about 10cm away from the shoulder, and if counted from the center of the body, one side is 30cm , and the round trip is 60cm, but considering that the earphone main body 1 is worn on the ear, it can be shortened by about 5cm, that is, the distance from the center of the body to the ear, so the optimal length is 55cm. the

The minimum required length is 45cm, the optimum length is 55cm, and 10cm before and after the optimum length is the optimum length range. Therefore, the length of the two branches of the earphone cord 3 from the fork 4 of the earphone cord to the earphone main body 1 L, preferably set as:

45cm≤L≤65cm (1). the

In addition, it is preferable to use an elastic material such as an elastic body such as silicone resin or vinyl chloride resin for the noise attenuation mechanism 6 of this embodiment. the

In this way, when the noise attenuation mechanism 6 in the connected state is arranged on the back of the neck, the pain caused when the earphone wire 3 is pulled to the plug 7 side and the noise attenuation mechanism 6 is pressed against the neck can be alleviated. When the earphone cable 3 is pulled toward the plug 7 by the force of the earphone wire, the noise attenuation mechanism 6 will be separated automatically, so as not to injure the neck or force the body to twist. The noise attenuation mechanism 6 plays the role of a safety mechanism. the

In addition, in this embodiment, the connecting part of the noise attenuation mechanism 6, as shown in FIG. The noise attenuation mechanism that has movable mechanism all can be adopted, as shown in Fig. 7 (a) can adopt the 1st connecting member 102 that has concave portion 1021, and the 2nd connecting member 103 that has convex portion 1031, (b) has O The first connecting member 104 of the type ring portion 1041, the second connecting member 105 having the C-shaped ring portion 1051, and also, as shown in (c) or (d), may have a prismatic key type portion that can be connected. , the first connecting member 106, the second connecting member 107, and the like that can slide in one direction. the

In addition, in the present embodiment, the connecting member of the noise attenuation mechanism 6, as shown in FIG. It may be a structure using a magnet or an attachable or detachable connector (sticky mouth, etc.), or a structure in which a magnet or an engageable or detachable connector is used to make the joint portion flat. the

Also, in the present embodiment, as shown in FIG. 1 , from the earphone main body 1 to the earphone cord fork 4 are two left and right earphone cords respectively covered by a kind of covering material, and the earphone cord fork 4 To the plug 7 is an earphone cable covered by another covering material, but it is not limited to this, the earphone cable 3 from the earphone cable fork 4 to the plug 7 can also be from the earphone main body 1 to An approximately single earphone cord is formed by joining a part of the covering material of the two left and right earphone cords 3 of the earphone cord branch portion 4 . the

In addition, in this embodiment, the earphone cord 3 having two branch lines can be provided with the earphone cord fork 4 on the two branch lines as shown in FIG. The earphone cord 3 from the earphone cord fork 4 to the plug 7 may also be formed by joining together a part of the respective covering materials of the left and right earphone cords 3 from the earphone main body 1 to the earphone cord fork 4 . strips of headphone cables, or other shapes. the

In addition, in this embodiment, the earphone cord 3 with two branch lines can be provided with the earphone line slider 5 on the two branch lines as shown in FIG. , because the two branch lines of the earphone line 3 are longer than the general earphone line, so the earphone line slider 5 is pulled up to the middle position of the two line parts, so that the effect that the two line parts of the earphone line 3 are not messy can be achieved when using the earphone. the

However, the earphone cord slider 5 may not be specially provided, and the earphone cord slider 5 may be replaced by a state in which the noise attenuation mechanism 6 of the present embodiment is connected. the

In addition, in this embodiment, as shown in Figure 1, the plug 7 is an L-shaped plug in which the front end of the plug and the insulating tube of the earphone wire are bent at 90 degrees, but it is not limited to this, and the front end of the plug and the insulating tube of the earphone wire can also be used. It is a linear straight plug or a plug of other shapes. the

In addition, in this embodiment, it is shown that the connection member of the noise attenuation mechanism 6 has the shape of the first connection member provided on the first earphone cord and the second connection member provided on the second earphone cord, but if the connection member It is a part that is provided on the first earphone cord and can connect the first earphone cord and the second earphone cord at the back of the neck, and may be in other shapes such as a C-shaped ring or a hook. the

【Industrial availability】
