Earphones with sound control {Ear phone having function for sound control}

The present invention relates to earphones, and more particularly to an earphone for controlling the sound reproduced in the audio device.

In general, the earphone is used in an audio device such as a cassette player or MP3, and is a kind of speaker that converts and outputs an electrical signal generated by the audio device into an audio signal.

That is, such an earphone receives a voice signal through a connection jack connected to an acoustic device, and the voice signal is output as an audio signal through the earphone speaker so that the user can listen to the sound to be listened to. Such earphones are easy to carry due to their characteristics, so they can be used with various portable audio devices, and the sound can be heard from the audio devices while moving or jogging.

This conventional earphone focuses on carrying a portable audio device in a pocket or a bag, and reduces or mutes the volume of the sound using the earphone without directly manipulating control buttons installed on the audio device. Sound control member was installed at a certain portion of the earphone cord to use.

However, when the weight of the conventional sound adjusting member is heavy, the weight is transmitted to the receiver plugged into the user's ear and may cause ear pain when the earphone is worn for a long time. In view of this, the sound adjusting member is mainly manufactured in a small size.

The sound control member manufactured in such a small size requires a fine finger movement when the operation is performed. Particularly, the operation of the sound control member is difficult in the case of a paralyzed patient or a disabled person or an elderly person whose body movement is unnatural. There was a problem of difficulty in use because it was not easy.

In order to solve the above problems, the present invention is to expand the range of the user's hand access to the part for the sound control to all or a portion of the earphone cord, earphones that can simplify the required sound control operation The purpose is to provide.

With reference to the accompanying drawings, the configuration of the earphone according to an embodiment of the present invention will be described in detail.

1 and 2, the earphone 1 of the present invention includes left and right receivers 11 and 13, a connection jack 30, a left and right cords 51 and 53, and a volume control unit 70. do.

The left receiver 11 and the right receiver 13 will be described by dividing them into left and right sides based on a state in which the user wears them on the ears as shown in FIG. 6.

The left and right receivers 11 and 13 include a speaker (not shown), which is a configuration employed in conventional stereo earphones, that is, each of them. In this case, the left receiver 11 is connected to the left signal line 51a and the left ground line 55a, and the right receiver 13 is connected to the right signal line 53a and the right ground line 55b.

The connection jack 30 has a configuration employed in a conventional stereo earphone, that is, a first terminal portion 31 electrically connected to the right signal line 53a, a second terminal portion 33 electrically connected to the left signal line 51a, And third terminal portions 35 electrically connected to ground lines 55c and 55d. In this case, the first to third terminal portions 31, 33, and 35 are insulated from each other by the insulator (I).

2 and 3, the left and right cords 51 and 53 have a predetermined length and connect the connecting jack 30 and the left and right receivers 11 and 13, respectively. In addition, the left cord 51 surrounds the left signal line 51a, the left ground lines 55a and 55c, and the right extension signal line 53b, and the right cord 53 includes the right signal line 53a, the right ground lines 55b and 55d, and The left extension signal line 51b is wrapped.

Specifically, the left and right cords 51 and 53 respectively include a first section and a volume control unit 70 to a part contacting the second stopper 74 at the tip of the left and right receiver 11 and the volume control unit 70, respectively. ) And a second section from the first stopper 72 of the volume control unit 70 to the portion in contact with the connection jack 30.

In the first section, the left cord 51 includes a left signal line 51a, a left ground line 55a, and a right extension signal line 53b therein, and the right cord 53 has a right signal line 53a and a right ground line. 55b and the left extension signal line 51b together. In this case, the left extension signal line 51b is branched from the left signal line 51a, and the right extension signal line 53b is branched from the right signal line 53a.

In this case, the right signal line 53a, the left extension signal line 51b and the ground line 55b of the first section are all made of a shape memory alloy.

In the first section, the left signal line 51a, the left ground line 55a, and the right extension signal line 53b are isolated from each other by the first and second spacers 61 and 63 made of an insulator. At this time, the first and second spacers 61 and 63 are formed with a plurality of through holes 61a and 63a at predetermined intervals, respectively.

In this case, the plurality of through holes 61a and 63a are used as passages through which the right signal line 53a, the ground line 55b, and the left extension signal line 51b are shorted to each other. That is, when the user presses any part of the first section of the right cord 53 to a predetermined pressure using a finger (see FIG. 6), the right signal line 53a, the ground line 55b, and the left extension signal line 51b. ) Is deformed through the heat generated by the pressing force and the body temperature of the user, pushed into the through-holes (61a, 63a) and becomes a short circuit state (see Fig. 7). As such, when the right signal line 53a, the ground line 55b, and the left extension signal line 51b are shorted, the sound transmitted to the left and right receivers 11 and 13 is cut off.

Meanwhile, in the case of the left code 51, the sound mute function may be implemented through the same process as in the right code 53.

Therefore, when the user releases the right cord 53 held down by the user, the pressing force applied to the right cord 53 is removed and the temperature of the pressurized portion is lowered so that the right signal line 53a, the left extension signal line 51b, and the ground line 55b are removed. Each is restored to a straight line. Accordingly, the wires 53a, 51b, 55b are isolated, the short circuit state is released, and the sound is transmitted to the left / right receivers 11, 13 again.

In this case, the restoration temperatures of the left and right signal lines 51a and 53a, the left and right extension signal lines 51b and 53b, and the ground lines 55a and 55b are restored to a straight line at 36.5 ° C. or less based on the user's human body temperature. .
