Recently, the number of users of mobile phones has been rapidly increasing due to the convenience of calls and mobiles that can be called anywhere, anytime. The use of the mobile phone is performed by using the handset in close contact with the earphone while holding the mobile phone by hand. As a result, there has been a problem that the handset portion becomes hot during electromagnetic waves generated for a long period of time.

In addition, the conventional earphone is inconvenient to carry the earphone by hand when not in use. As a result, the earphone is housed in a pocket or a bag and stored. At this time, the earphone wire is wrapped around the earphone wire and the earphone wire is twisted or twisted. This repeated phenomenon frequently causes short-circuiting of the electric wire embedded in the earphone wire.

In the figure, reference numeral 35 denotes a torsion spring for elastically biasing the winding roll 13 in the initial state so as to restrict the removal of the winding roll 13 from the boss 18 by the connection box 31, And a hook 37 for fixing the inner lid 25 to the engaging hole of the mobile phone case 12. The inner lid 25 is fixed to the inner case 25 by a hook.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an example of using a mobile phone case having an earphone winding part according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figs. 1 to 7, the cellular phone A is housed in a housing part formed on the front face of the cellular phone case 12 having an arbitrary character shape, and is rotatable on the back face of the cellular phone case 12. [ The earphone head 10 of the earphone wound around the winding roll 13 mounted on the earphone holder 12 can be housed in the earphone head holder 11 protruding from the back surface of the mobile phone case 12. [

Therefore, when the mobile phone A is accommodated in the mobile phone case 12 and carried, the earphone is accommodated in the mobile phone case 12 and is stored and carried. Therefore, the use of a separate earphone case for storing and carrying the earphone It becomes unnecessary.

Hereinafter, the winding process of the earphone wire 14 to the winding roll 13 will be described in detail with reference to the accompanying drawings.

The earphone wire 14 is wound on the outer surface of the winding roll 13 supported rotatably about the boss 18 of the braking block 19 mounted on the back surface of the mobile phone case 12 .

When the earphone wire 14 wound around the winding roll 13 is pulled out and pulled out from the winding roll 13, the first receiving portion 13a of the winding roll 13, which is rotated about the center axis of the boss 18 by an external force, Shaped spiral spring 24 housed in the spiral spring 23 is wound as in the case of the spring spring.

On the other hand, when the external force pulling the earphone wire 14 is removed, the earphone wire 14 is wound on the outer side of the winding roll 13 rotated by the elastic restoring force of the spiral spring 24 It will become cold.

In detail, when the earphone head 10 stored in the earphone head holder 11 is pulled out and then pulled upward (referring to the earphone head holder 11) to use the earphone, The wire 14 is drawn along a groove 26 formed at the edge of the outer cover 16 by a user's desired length.

At this time, as the winding roll 13 is forcibly rotated by an external force pulling the earphone wire 14, the braking groove 20 of the rotating winding roll 13 is rotated in the corresponding braking block 19 "of the" braking projection 17 ".

Therefore, the winding roll 13, which is rotated so that the earphone wire 14 is unwound, is rotated about the boss 18 as a center axis (in this case, the spiral spring 24 is wound like a spring in a tensioned state) .

When the wind-up roll 13 is rotated by an external force pulling the earphone wire 14, a connection (not shown) mounted inside the inner lid 25 so that the earphone jack 30 of the earphone is connectably connected The box 31 is rotated.

The connecting box 31 is kept idle with respect to the inner lid 25 even when the winding roll 13 is rotated by forcibly pulling the earphone wire 14, It is possible to prevent twisting of the earphone wire 14 even when the earphone jack 30 of the earphone wound around the winding roll 13 is connected to the connection box 31. [

The connection earphone jack 27 of the extension type terminal 32 connected to the connection box 31 can be connected to the jack insertion port of the mobile phone housed in the mobile phone case 12. Therefore, it is possible to receive a predetermined voice signal by using the earphone head 10 of the earphone connected to the cellular phone A.

When the earphone wire 14 is pulled out by pulling up the earphone wire 14 by an arbitrary length and the external force pulling the earphone wire 14 is removed, the rotation of the winding roll 13 and the winding action of the spiral spring 24 Stopped. The braking protrusion 17 of the braking block 19 is moved in the axial direction toward the braking protrusion 17 of the braking block 19, (20) is concavo-convex coupled.

Therefore, the earphone wire 14 is no longer unwound from the winding roll 13, and is drawn out to the outside of the outer cover 16 by a user's desired length.
