Abstract

The utility model discloses an earphone including an earphone line, plastic shells, a runner, a pyramidal under surface and a fixed body. The rotatable runner is blocked in the two plastic shells and then the plastic shells wrap the winded earphone line having enough length, so as to realize the aim of making the earphone line flexible. And the dismountable and replaceable pyramidal under surface is designed. Thus, a rotation function of a top is realized in the utility model.

Description

A kind of earphone

Affiliated technical field

The utility model relates to the earphone that a kind of earphone cord can stretch.

Background technology

Present earphone great majority can not the telescopic earphone line; Earphone cord is intertwined easily, uses inconvenience, causes user's inconvenience; The structure of the earphone of the scalable line that has also more complicated causes that cost an arm and a leg can't be well popular on the market, and function ratio is more single.

Summary of the invention

The purpose of the utility model provides a kind of earphone of telescopic earphone line, and this earphone can manually freely change the length of earphone cord, and the gyro function is arranged.

The utility model solves the technical scheme that its technical problem adopted: a kind of earphone comprises earphone cord, runner, plastic casing, card body, centrum bottom surface, fixed body; It is characterized in that: combine into earphone cord and plastic casing (2) and the runner (3) that can change as a whole; Internal phone line (1) and the detachable combination of plastic casing (2); Plastic casing (2) encases the earphone cord (1) of winding, and runner (3) is realized the contraction of earphone cord (1) through rotation.Wherein centrum bottom surface (5), fixed body (6) can split the two commutative use with plastic casing (2).

The beneficial effect of the utility model is, when occurring causing earphone cord length not enough owing to the equipment reason, can satisfy the demands through the length that the manual adjustments runner freely changes earphone cord, makes it can continue use.And owing to increased cone-shaped bottom surface and can serve as gyro.

Description of drawings

Below in conjunction with accompanying drawing the utility model is done further explain.

Fig. 1 is the structure principle chart of the utility model,

Drawing explanation: 1. earphone cord, 2. plastic casing, 3. runner, 4. card body, 5. facies basialis pyramidis, 6. fixed body

Embodiment

A kind of earphone comprises earphone cord, plastic casing, runner, card body, centrum bottom surface, fixed body.

Earphone cord (1) is enclosed in two plastic casings that can be buckled together (2) lining after twining; Making the flexible runner (3) then of earphone cord (1) blocked body (4) through hand runner (3) blocks; Prevent that earphone cord from skidding off, move card body (4) with hand during use, pull out earphone cord then and get final product.Take plastic casing (2) apart, after extracting earphone cord (1) and fixed body (6), install facies basialis pyramidis (5), fasten plastic casing (2) then again, hand Rotating wheel (3) can be realized the spinfunction of gyro.

Claims (2)

1. an earphone comprises earphone cord, runner, plastic casing, card body, centrum bottom surface, fixed body; It is characterized in that: combine into earphone cord and plastic casing (2) and the runner (3) that can change as a whole; Internal phone line (1) and the detachable combination of plastic casing (2); Plastic casing (2) encases the earphone cord (1) of winding, and runner (3) is realized the contraction of earphone cord (1) through rotation.
