Abstract

The utility model relates to a lead wire reeling-in type earphone which uses hands to reel in the lead wire of the earphone, comprising a plug, a lead wire reeling-in box which is integrated with the plug, and an earphone. When the earphone is not used, two hands respectively hold the upper and the lower two parts of the lead wire reeling-in box, the lower half part of the lead wire reeling-in box is counterclockwise rotated, and the long lead wire of the earphone is reeled into the small lead wire reeling-inbox. The earphone is conveniently stored for users, and the utility model avoids accidents that the earphone, the lead wire, the plug or the radio device are damaged by users by accident.

Description

Wire reeling-in type earphone

The utility model relates to the earphone of the small-sized radio-tape recorder of a kind of walkman class, a kind of Wire reeling-in type earphone that can reclaim lead-in wire of more specifically saying so.

The earphone that existing various stereo sets, the particularly small-sized radio-tape recorder of walkman class are disposed all has long lead-in wire.When earphone does not use, take care of least easily so, easily twine and form fast knot, cause the lead-in wire internal break, this has influenced the useful life and the acoustics of earphone to a certain extent.Though have a kind of automatic Wire reeling-in type earphone (seeing number of patent application 93246512.9) to address the above problem at present, but because this automatic Wire reeling-in type earphone has adopted the clockwork spring retracting device, dynamic and static contact ring device, make its processing technology complexity, volume is difficult to dwindle, and particularly can't keep the stable channel status from the earphone to the plug for a long time.

The purpose of this utility model is in order to solve the weak point of automatic Wire reeling-in type earphone, thereby a kind of manual Wire reeling-in type earphone of design, this earphone in use, earphone wire can be involved to random length, when stopping using,, then the bottom is done being rotated counterclockwise and lead-in wire can being regained in the box as long as arrest the upper and lower two parts of winding box respectively with two hands.

The purpose of this utility model can realize in the following manner:

A kind of Wire reeling-in type earphone of manual recovery earphone wire, comprise plug, with the exhausting line box and the earphone of plug disjunctor.The Lower Half center of exhausting line box have one with the rotating shaft of plug disjunctor, earphone wire coiling axle is gone up and is connected with plug in axle.

The utility model compared with prior art, its advantage is: when using Wire reeling-in type earphone broadcast listening or music appreciating, the user can be with a upper half part that holds the exhausting line box, after the another hand is hauled out earphone wire plug is inserted in the earphone jack of radio-tape recorder just passable.When finishing use, with a upper half part that holds the exhausting line box, the another hand is done the lower portion of exhausting line box and is rotated counterclockwise, and very long earphone wire just can be recovered in the exhausting line box easily.Keeping is got up very convenient like this, can avoid damage because of earphone, lead-in wire, plug, socket or the stereo set itself that the user causes because of carelessness, thus solved again automatic Wire reeling-in type earphone volume greatly, not attractive in appearance, processing technology is complicated, cost is high, particularly its dynamic and static contact easily forms loose contact and causes keeping for a long time numbness diseases such as stable channel status from the earphone to the plug.
