Abstract

Provided is an earphone, which relates to an earphone capable of storing earphone lead, and comprises a pair of earphone body, lead, a lead storage box and a plug. The utility model is characterized in that the lead storage box consists of a housing, a spring box, a spring leaf and a lock pin; the spring leaf is arranged in the spring box, forming a spring resetting mechanism; the two spring boxes are respectively arranged on the expandable shaft in the housing and the lock pin is inserted in the expandable shaft; the lead is winded on the outer ring of the spring box, and one end of the lead is connected to the earphone and the other end is connected to the plug through a lead connecting ring; grooves are arranged at two sides of the housing, and spring cards are arranged at two sides of the groove to place the earphone; a switch thimble is arranged in the groove to control the earphone switch; a switch which is corresponding to the switch thimble in the groove of the housing is arranged at the inner side of the earphone handle. The utility model with a structure being similar to a ruler tape is advantageous in that the lead length of the earphone can be determined based on demand, thereby the utilization is facilitated and the lead is not easy to be coiled; when not in use, the earphone is powered off, saving power.

Description

Earphone

Technical field

A kind of earphone relates to a kind of earphone of taking in earphone lead function that has.

Background technology

Now the earphone that uses of people generally all is paired, line length be fixing, and line length is limited.People in use, line is oversize to be intertwined easily, lacked very much use very inconvenient.Sometimes, when only using one, another is also being opened, and causes waste of electric energy.

The utility model content

The purpose of this utility model provides a kind of earphone cord of taking in, and two earphones that earphone can separately use.

This earphone is made of a pair of earphone, lead, winding box and plug; Winding box is to be made of shell, spring case, spring leaf and lock pin; Spring leaf is contained in the spring case, and the outer end of spring leaf is fixed on the spring case, and the inner of spring leaf is connected on the interior main axis of dilatation of shell, constitutes spring reset mechanism; Two spring cases are distinguished on the cased expansible shaft, and can rotate around main axis of dilatation; Lock pin is inserted in the main axis of dilatation, in order to the rotation of restraining spring box; Lead is wrapped on the outer ring of spring case, and an end links to each other with earphone respectively, and the other end links to each other with the lead connecting ring that is contained in the main axis of dilatation two ends respectively; The both sides of shell are done fluted respectively, and Spring Card is equipped with on the both sides of groove, are used to place earphone, and the switch thimble is housed in groove, are used to control the switch of earphone; Plug links to each other with the lead connecting ring by lead and brush; Switch is equipped with in the inboard of earphone handle, and is corresponding with the switch thimble in the shell upper groove.

The similar of this earphone is in the box chi.During use, pull up lock pin, spring case can be rotated.Take off earphone, one or two, lead is moved to the length that needs.Then lock pin is turned back in the main axis of dilatation, pin spring case, the length of promptly fixing lead.At this moment, earphone can normally use.After using up, extract lock pin again, under the effect of spring leaf, the spring case revolution can be recovered to lead in the winding box.When earphone was placed on the winding box, because the effect of switch thimble, earphone was closed, and does not promptly use not power consumption.The conductor length of this earphone is as required and fixed, thereby uses more conveniently, is difficult for twining.
