Abstract

The present invention is a earphone set used in a mobile phone or MP3, etc. is provided with a device that can wind up the earphone wire and store the earphone connected by a portable string (string) in normal use as a portable string and can be used to withdraw the earphone when needed An object of the present invention is to eliminate the hassle of carrying a wire.

By rotating circuits such as selection buttons or microphones directly on the winding bobbins of the winding and storage housings together with the component bobbins, a complete contactless circuit can be constructed and a circuit in which one strand of wire splits into two earphones is formed in the housing As a result, the thickness of the wire due to the knot can be overcome. The winding and withdrawal control device formed by the guide groove and the stopper ball is formed with the guide groove so that the bobbin is stopped at a certain angle to expose the button or the microphone to the outside of the housing. When the wire is wrapped or the earphone is stored, the stopper formed on the wire close to the earphone prevents the bobbin from rotating, so the wire on the side that is not drawn out can be used as a strong string.

Description

Earphone set with a winding device that combines a portable file {A earphone set}

The present invention relates to an earphone set that we usually use in a mobile phone or MP3, etc. It is an earphone set that allows us to use the wire withdraw the wire when using a call or earphone, and just use the wire as a portable string when carrying.

In recent years, mobile phones and MP3s have become widespread and many people are using earphone sets. However, carrying and storing long stretched earphone wires when not in use has not been cumbersome. To solve these problems, products with various winding devices were introduced, but the winding and withdrawing of wires were made in one direction or controlled. In order to extinguish the required length due to the inefficiency of the device, there has been a closure such as bulkiness or difficulty in operation. The present invention solves this problem. It is an easy-to-use portable earphone set composed of circuit contacts and strings to have the best functions.

Earphone sets such as conventional mobile phones and MP3s can be used to stretch the earphone wires for long periods of time. After use, they can be stored in a crumpled or tangled state without any breakage or damage due to contact or impact with the outside. Not only that, it was not inconvenient to carry. Although various types of winding devices have been introduced, it has not been put to practical use due to the inconvenience of carrying and using. It is an object of the present invention to provide a set of earphones that can be used by anyone and easy to use and portable to solve such problems.

In order to achieve the above object, the present invention provides a device for winding and storing at a point where the earphone set wire is divided into two strands from the connecting jack 3 to the two earphones 2, and the wire of the connecting jack has a predetermined length of wire (4) and a stopper (9) formed close to the earphone. The winding and storage device of the earphone set thus constructed has a guide groove (17) having a locking jaw at the bottom thereof, and a winding bobbin. Housing (1) provided with space for exposing button (5), microphone (6), etc. on the central shaft (30), wire outlets (31, 32), earphone housing (26), and upper surface (29) rotated. Spiral spring 20 is connected to the central axis 30 and the bobbin 29 to have a rotation restoring force therein, and the stopper of the sawtooth (9) to prevent the combined rotation of the stopper (9) at its edge (28) Partition plates (13,14, 15,16,) are installed in three compartments on the outside of the bobbin 29 so that the wire 8 and the two rows of wires 7 can be wound independently. The bottom plate 16 has a stopper ball 18. To form a guide groove 19 of a predetermined length to rotate along the guide groove 17 in the center direction on the bottom. On the upper plate 13 of the bobbin 29, the wirings 10 of the wires 7, 8 passing through the plate 13, the buttons 5, the microphone 6, and the like, which constitute a mounting circuit 10 ) And its cover 12 are completed by forming screws (11).

Conventional earphone sets were not inconvenient to store or carry due to tangled or bulky wires. The present invention is equipped with a device that can easily wound and withdraw the wire when necessary to eliminate such inconvenience, the volume is small, easy to carry and store, as well as to protect the earphone in the protective case 26, the earphone and wire Attached to the line (4) can be used as a portable file.

When described in detail based on the accompanying drawings as follows. As shown in FIG. 1, the present invention accommodates two earphones 2 and winds wires, and includes a winding device having a control button 5 or a microphone 6, and a wire 8 on the side of the connecting jack 3. It is a structure formed by forming a string (4). The housing 1 constituting the winding device has two circles, a hooking jaw, and a connection forming a device for controlling the bobbin 29 to be rotated, stopped, and reversely rotated as shown in FIG. A guide groove 17 formed of a passage and a central shaft 30 to which the bobbin rotates may be formed, and the button 5 or the microphone 6 may be exposed on the wire outlets 31 and 32, the earphone housing 26, and the upper surface thereof. The inside of the bobbin 29 is mounted with a spiral spring 20 so as to have a restoring rotational force after withdrawing the coupling wire to the central axis 30 and the bobbin. Jacks (3, 14, 15, 16) for partition plates (13, 14, 15, 16) having tooth-shaped engaging grooves (28) formed so as to be fixed by a stopper (9) formed at the wire on the earphone (2) side of the circle. Two rows of wires (8) on the side and wires (7) on the earphone side, respectively. Fit a price. The bottom surface of the partition plate 16 forms a guide groove 19 of a constant length in the direction of the center of the circle so that the stopper ball 18 can be rotated along the guide groove 17. On the upper side of the partition plate 13, the PCB 10 and the cover 12, which constitute circuits such as the wiring 21, the control button 5, the microphone 6, and the like of the wires 7 and 8 provided through the plate. ) Is assembled to the forming housing with screws (11). In the earphone set according to the present invention, the wires of one strand 8 toward the connection jack 3 and the two strands 7 toward the earphone are wound and drawn in both directions, independent of each other by the action of the partition plate. It is coiled regularly. Since the wire is wound on both sides, it is possible to wind the length of the wire in proportion to the number of revolutions rather than winding in one direction. By pulling and releasing the wire 7 by the action of the guide groove and the stopper ball (FIG. 3A), the wire 7 is stopped and restored by pulling and releasing the wire 7 so that a wire having a desired length can be easily obtained as necessary. Since the PCB 10 itself rotates like a bobbin, a solid contactless circuit can be obtained, and the PCB stops at a predetermined angle due to the action of the guide groove 17 of the present invention so that the control button 5 or the microphone 6 can be obtained. The back may be exposed to the outside through a space formed on the upper surface of the housing. The storage space 26 of the earphone may be easily caught when the exposed space 27 is formed and drawn as shown in FIG. When the earphone is to be exposed to the outside of the housing 1, it can be manufactured as a housing without the earphone housing 26 as shown in FIG. When the cord 4 is connected to a main body such as a mobile phone or an MP3, the stopper 9 and the locking groove 28 do not pull the earphone 2 directly while the housing 1 is pulled out. string).
