CN201878303U - Earphone connecting line - Google Patents

Abstract

The utility model discloses an earphone connecting line, one end of the connecting line is connected with an earphone main body, while the other end of the connecting line is connected with a plug; a left ear line, a right ear line, a ground line and a microphone line are arranged in a plastic sheath of the connecting line, the ground line is wound on the microphone line; an additional ground line respectively arranged in parallel to the left ear line, the right ear line, the ground line and the microphone line is also arranged in the plastic sheath of the connecting line. Compared with the prior art, the earphone connecting line has no obvious influence on integral structure and size, the cost is slightly increased but the comprehensive cost is not high, the social benefit is remarkable, the service life of the earphone is effectively and greatly prolonged; the earphone connecting line is energy-saving and consumption-reducing and environment-friendly.

Description

A kind of earphone connecting line

Technical field

The utility model relates to a kind of earphone connecting line, is meant a kind of earphone connecting line with double earth wire especially.

Background technology

The connecting line of existing commercially available earphone all adopts the four-wire system structure, be headset plug to one having four lines between microphone case: left tramline, auris dextra line, ground wire and microphone lines, add and man-hour ground wire is wrapped on the microphone lines, outside four lines, be covered with its colligation plastic cement skin together then.In daily use, connecting line is in the bending of external force at any time and stretches down, and this configuration state of connecting line makes the lead in the connecting line be easy to fatigue occur, and the ground wire that particularly is wrapped on the microphone lines is prone to the phenomenon that fractures.In consumer's use, ground wire is the easiest to break, and becomes the short slab of wooden barrel, and during actual analysis market ear-phone function was bad, what ground wire was disconnected accounted for 80 percent.

The utility model content

The purpose of this utility model provides a kind of earphone connecting line that overcomes ground wire frangibility problem in the existing earphone connecting line.

Designed a kind of earphone connecting line according to above-mentioned purpose, described connecting line one end is connected with the earphone body, an end is connected with plug, the outer intracutaneous of the plastic cement of this connecting line includes left tramline, auris dextra line, ground wire and microphone lines, described ground wire is wrapped on the microphone lines, also include an additional ground wire, this additional ground wire is set up in parallel with left tramline, auris dextra line, ground wire and microphone lines respectively.Under this structure,, but, guaranteed that ear-phone function is normal owing to also have an additional ground wire to exist even the ground wire that is wrapped on the microphone lines ruptures.

The utility model does not compared with prior art make significant difference to overall structure and size, and integrated cost is not high though cost slightly rises, and social benefit is obvious, improves and prolonged significantly the machine life of earphone effectively, is beneficial to energy-saving and cost-reducing and environmental protection.

Description of drawings

Accompanying drawing 1 is the structural representation that dissect prior art assembling back; Accompanying drawing 2 is structural representations that dissect the utility model assembling back.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

With reference to accompanying drawing.Fig. 1 gives the basic structure of having shown earphone connecting line when using prior art, described connecting line comprises plastic cement system crust 5, fabric endothelium and heart yearn, heart yearn is by left tramline 1, auris dextra line 2, ground wire 3 and microphone lines 4, and wherein ground wire is wrapped on the microphone lines in a spiral manner.The effect that ground wire is wrapped on the microphone lines in a spiral manner is: play shielding action, ground wire is prone to the phenomenon that fractures to make the external world not disturb the signal that transmits on the microphone lines, this structure to cause in use.

Fig. 2 gives and has shown that the technical scheme that the utility model provides, the purport of this technical scheme are to solve the problem that fractures that ground wire in use is prone to.Because the space is narrow and small and the restriction of cost, adopt direct mode to be difficult to solve ground wire problem easy to break, does that have not subplan? the utility model has proposed a scheme of dealing with problems from the side.Promptly in the basic structure of earphone connecting line, increase an additional ground wire 6, this additional ground wire is set up in parallel with left tramline, auris dextra line, ground wire and microphone lines respectively.Simple in structure, practical, the easily enforcement of the utility model, cost increases limited, and in not changing profile and increasing hardly under the prerequisite of wire geometry size, has effectively improved the useful life of earphone connecting line and the machine life of earphone.

Claims (2)

1. earphone connecting line, described connecting line one end is connected with the earphone body, an end is connected with plug, the outer intracutaneous of the plastic cement of this connecting line includes left tramline, auris dextra line, ground wire and microphone lines, and described ground wire is wrapped on the microphone lines, it is characterized in that: also include an additional ground wire.

2. earphone connecting line according to claim 1 is characterized in that: described additional ground wire is set up in parallel with left tramline, auris dextra line, ground wire and microphone lines respectively.
