Description

Hands free earphone apparatus {Hands free earphone apparatus}

The present invention relates to a hands-free earphone device that can be plugged into the ear-microphone jack of a mobile phone, and more particularly, a microphone or a speaker and an on-off switch of a transmission / reception function in a single earphone device, as well as control means for entering and exiting a cord. The integrated hands-free structure allows the hands-free structure to be very simple, and the operation of each function is simple and convenient, allowing quick transmission and reception even when the earphone device is used by ear or withdraws a cord whenever necessary. It relates to a hands-free earphone device that there is no rejection at all according to the installation.

In general, hands-free means that a mobile phone (communication equipment) user can easily talk to the other party without having to pick up the mobile phone even when he or she is hard to talk directly with the mobile phone. It was developed for this purpose. And the hands-free is connected to the mobile phone to enable additional transmission and reception, the microphone of the transmission function, the speaker and the on / off switch of the receiving function, the plug plugged into the ear-microphone jack of the mobile phone is connected and It consists of a cord of a predetermined length electrically connected to a microphone, and a speaker having a reception function is generally installed in an earphone. Therefore, a hands-free device that is conventionally used will be schematically described with reference to Figs.

The hands-free device shown in FIG. 1 has a predetermined length of cord 5 connected to a microphone 2 of a transmitting function, an on-off switch 3 and a plug 4 with respect to the earphone 1 having a speaker having a receiving function. Each of them is separately installed, especially in the case of the hands-free device shown in Figure 1 is configured to be hooked to the ear with a separate ear hanger (6), which is inserted into the ear when transmitting and receiving a structure, having a predetermined length Cord 5 is a structure that is used in the always released state without a separate winding mechanism.

Therefore, in the case of the hands-free device, the earphone 1 has only a built-in speaker (not shown) of the receiving function, and the rest of the functions are separately separated from the microphone 2 of the transmitting function and the on-off switch 3, for example. If you want to make a call with the plug (4) of the cord (5) plugged into the ear-microphone jack of the mobile phone, insert the earphone (1) into the ear after each call, and then the ear hanger (6). It is inconvenient and hassle to make a call by operating the on-off switch 3 separately after fixing it on the ear. As a result, it is not easy to quickly operate the function according to the call, and the portable storage according to the distributed installation of each function There is a problem that is not easy. On the other hand, in order to alleviate this hassle, the earphone (1) is always plugged into the ear, and the on-off switch (3) can be easily manipulated to make a call when needed. In this case, the earphone (1) is used for each call. Discomfort and troublesome to install every time can be solved to some extent, but because the microphone (3) of the structure of the earphone (1) is installed to extend long near the mouth, it is not only cumbersome and uncomfortable, especially the rejection of the earphone (1) There is a problem that you can have.

And in the case of the hands-free, although the cord 5 has a considerable length, there is no separate winding mechanism, so it is impossible to use the drawer to an appropriate length, and the cord becomes tangled and cumbersome as it is always used in a stretched state. There is a big problem.

Meanwhile, the hands-free device shown in FIG. 2 is an advanced technology compared to FIG. 1, and as shown in FIG. 2, the earphone 10 includes a speaker 11 having a reception function, a microphone 12 having a transmission function, and an on-off state. Since the switch 13 is integrally installed, the on-off switch 13 can be operated at the same time by inserting the earphone into the ear during a call, and the cord 14 connected to the earphone 10 has a separate winding mechanism. It is configured to be wound by (15) or released by a predetermined length therefrom, and the cord (17) connected to the board with a relatively short cord (16) separate from the cord (14) connected to the earphone (10) is installed at the end thereof. ) Is plugged into the ear-microphone jack of the mobile phone to make a call.

Accordingly, in the case of the hands-free, both the transmission and reception functions 11 and 12 and the on / off switch 13 functions are integrally installed in the earphone 10, and the cord 14 having the relatively long length connected to the earphone 10 is Since it is configured to be wound or unwound by a separate winding mechanism 15, it is quite simple and convenient as compared to the hands-free of the former, and at the same time, the earphone 10 is inserted into the ear or plugged in during the call. It is a technological advance that can be manipulated to allow for faster phone calls and easier code storage.

However, since the handsfree is also configured to be wound or unwound by a separate winding mechanism 15 when the earphone 10 is used, the handsfree is not compact, and the entire volume is not only large, but also the cord 14 Unlike the earphone 10, the winding mechanism 15 has to be separately installed and hassle in the manufacturing process, and in order to secure the winding of the cord 14, the winding mechanism 15 is fixed in a separate place. There is a problem in use that has to be attached or attached, and in particular, when the winding mechanism 15 is attached as a double-sided tape, there is a problem that it is difficult to move to another place. And the cord 16, the plug 17 is installed is always drawn out by a predetermined length to plug into the ear-microphone jack of the mobile phone without a separate winding mechanism, which is too cumbersome to use.

Therefore, the present invention is to solve the above problems, the object of the present invention is to allow the ear to be used in hands-free earphones at the same time, in addition to the receiving function, as well as the transmission function of the winding function and the on-off switch function It is equipped with an integrated zoom, which makes it easy to operate each function in the earphone itself. Also, since each function is built in the earphone device, there is no objection to wearing and the overall structure of the handsfree is simple and compact. Not to provide a hands-free earphone device that can have a fashion effect at the same time when wearing.

Is provided with a cord winding mechanism 122 for automatically unwinding or winding a cord 120 having a predetermined length, and the cord winding mechanism 122 is a winding reel in which a cord 120 of a predetermined length is wound and unwound. 123 and a cord entry / retrieving means 124 for unwinding and winding the cord 120 with respect to the winding reel 123.

The coiling reel 123 has two flanges 126a and 126b for forming the cord receiving portion 125 integrally formed at regular intervals, and is formed as a central portion of the one side flange 126a. A spring receiving groove 127 is provided, and the spring receiving groove 127 is elastically installed with the spring spring 128. At this time, the spring spring 128 has one end protruding from the case body 110. And the other end is fixed to the central shaft 129 penetrated by the spring receiving groove 127 of the take-up reel 123, and the other end is connected to the engaging piece 127a formed at one side of the spring receiving groove 127. While each is fixed, the winding reel 123 is forcibly rotated forward and backward.

The lower end of the flange 126b of one side of the winding reel 123 is rotated in a winding direction (counterclockwise) of the cord 120 by a cord input and output operation means 124 to be described later at regular intervals. The locking jaw 130 for restraining is protruding, and the blacking release jaw 131 for releasing the locking when the cord 120 is rotated in this direction (clockwise) when the cord 120 is released with respect to the locking jaw 129 is provided. It is formed continuously curved. The locking jaw 130 and the locking release jaw 131 is formed in about four places in the drawing bar and the release operation is performed, the installation interval is not necessarily limited to this.

Meanwhile, when the cord 120 is unwound or wound from the winding reel 122, the cord entry / exit operation means 124 for enabling the reverse rotation thereof is a slide 132 that is installed to be slidably movable in the case body 110. ) And the locking force of the winding reel 123 while the locking piece 133c of one side is elastically driven by the elasticity of the spring 134 installed on the other side with respect to the support shaft 133a according to the operation of the slide 132. Lock 133 is provided to give or release.

One side of the slide 132 is exposed to the outside of the case body 110, and is typically protruded to the other end of the button 132a for operation with the thumb to be caught by the operation groove 133b of the lock 133. The operation pin 132b to be inserted is formed. At this time, the operation pin 132b comes into contact with the inclined surface 133b-1 of the operation groove 133b, and the operation groove 133b is a locking piece 133c. In the proximal position of), the narrower it is, the farther it is, the wider it is.

Accordingly, as shown in FIG. 5, in the state where the winding reel 123 is locked by the cord entry / exit operation means 124, the operation pin of the slide 132 inserted into the operation groove 133b of the lock 133 ( Since the 132b is moved to the extended portion of the operation groove 133b and is located in a loose state, the locking release jaw 131 formed therein is formed when the winding reel 123 is rotated in the clockwise direction (arrow A direction). Even when the locking piece 133c of the lock 133 is pushed outward, the lock 133 is moved and operated about the support shaft 133a by the spring 134 without interference of the operation pin 132b, so that the cord 120 It is continuously drawn out, even if the take-up reel 123 is reversed by the reaction force of the spring spring 128 in the withdrawal process of the cord 120, the locking jaw 130 is the locking piece 133c of the lock 133 At the same time, the reverse rotation is prevented, and at the same time, the cord 120 that was released is no longer wound.

However, when the operation pin 132b of the slide 132 is moved to the narrow operation groove 133b of the lock 133 as shown in FIG. 6, the operation pin 132b of the slide 132 is the operation groove 133b. The lock 133 is naturally rotated by the spring 134 around the support shaft 133a as it moves while being in contact with the narrowed inclined surface 133b-1, and at the same time the locking jaw 130 The engaging piece 133c that has been engaged is forcibly pulled to move outward, and the winding reel 123 is released by the locking force released by rotating the counterclockwise direction (arrow (B) direction). When it is automatically wound by the reaction force of 128, and the winding operation is completed and the slide 132 is moved to the position of FIG. 5 again, the locking piece 133c of the lock 133 again has the restoring force of the spring 134. As the original position is caught by the catching jaw 130 of the take-up reel 123, reverse rotation is prevented.

Meanwhile, as shown in FIG. 5, the on-off switch 116 installed in the earphone device 100 is installed at approximately 10 o'clock, and the slide 132 for winding operation of the cord 120 is positioned at 3 o'clock, respectively. The index finger is positioned on the on-off switch 116 of the earphone device 100 according to the transmission and reception, and the thumb is positioned on the slide 132 so that the manipulation thereof is quick and easy.

In addition, as shown in FIG. 7, the rotary substrate 135 installed below the center of the flange 126b of the winding reel 123 is rotated together with the winding reel 123 rotatably penetrated about the central axis 129. At the same time, one end of the cord 120 wound around the cord receiver 125 is firmly fixed in the same manner as soldering, and the rotating substrate 135 has a fixed substrate 136 to which the speaker 113 is electrically connected and fixed. It is always in contact via the terminal.

The state of transmitting and receiving using the earphone device 100 of the present invention configured as described above will be described with reference to FIGS. 5 and 6.

At this time, the spring spring 128 elastically installed in the spring receiving groove 127 of the winding reel 123 is It is opened as far as the edge of the spring receiving groove 127 by the elastic force, the winding reel 123 is a state in which the locking force is given by the operation means 124 for entering and exiting the cord is preventing further reverse rotation.

In this state, the cord 120 must be drawn out to a proper length in order to transmit and receive. In the present invention, first, the plug 120a installed at one end of the cord 120 is plugged into the ear microphone jack of the mobile phone, and then fixed. It will pull (100). At this time, the cord 120 is automatically released by the winding reel 123 of the cord winding mechanism 122 rotated in the direction of the arrow A, and the cord 120 is prevented from being rotated backward by the lock 133. ) Is not cold.

That is, when the slide 132 of the cord entry and exit operation means 124 is operated as shown in FIG. 5, the engaging release 133 formed therein at the time of rotation of the take-up reel 123 is the engaging piece 133c of the lock 133. At the same time, the lock 133 is returned again by the restoring force of the spring 134 so that the take-up reel 123 is always caught even when the pull-out operation of the cord 120 is stopped or paused. As the locking step 130 is mutually walked by the reverse rotation is prevented and thereby the cord 120 released to a predetermined length is also not rewinding. As the cord 120 is loosened, the spring spring 128 is forcibly compressed and retracted toward the central axis 129.

Therefore, the caller uses the earring 115 as shown in FIG. 8 to fix the earphone device 100 to the ear or to fix it to the ear whenever necessary, and then operates the on-off switch 116 to zoom the speaker 113 and the microphone 118. In this case, in particular, the microphone 118 is formed so that the microphone mounting piece 119 extends curvedly with respect to the case body 110, so that the sound transmission through the sound absorbing hole 119a is more reliably performed. It can be done.

In this way, when the call is completed by hanging the earphone device 100 on the ear and the cord 120 in the withdrawn state is to be wound on the winding reel 123 in the earphone device 100, the slide 132 is downward as shown in FIG. When pulled out, the operation pin 132b inserted into the operation groove 133b of the lock 133 is brought into contact with the inclined surface 133b-1 to be moved to a narrow portion, and the lock 133 moves the support shaft 133a. The spring 134 is pulled outward while the center is pulled out, and the locking piece 133c thereof is forcibly released from the locking step 130 of the winding reel 123 as the lock 133 is pulled.

Therefore, the winding reel 123 is completely wound around the cord 120 while rotating several times in the direction of the arrow (B) by the reaction force of the spring spring 128 as the locking force of the lock 133 is released by the operation of the slide 132. When the cord 120 is wound stably by the cord entry and exit guide piece 121, and the winding operation of the cord 120 is completed, the slide 132 is pushed again as shown in FIG. The winding reel 123 is hooked and fixed again by the lock 133.

On the other hand, since the earphone device 100 of the present invention has a transmission and reception function and a switch function as well as a winding device of a cord at the same time, the earphone device 100 is always fixed to the ear as shown in FIG. Even when the cord 120 is pulled out from the mobile phone 140 every time, various functions are very easy and easy to operate, so that quicker transmission and reception are possible. In particular, when the earphone device is placed on the ear, the ears are covered as a whole and the transparent cover plate on the surface. In 117, a variety of characters, pictures, and the like are adorned with a sticker on which appearance of beauty can be produced.
