Abstract

A plug-in earphone relates to the field of earphones, in particular to an earphone of which an earphone receiver and a wire are separated. The key component of the earphone is the earphone receiver. As the earphone receiver and the wire in a conventional earphone are welded together, the earphone receiver is easy to damage. In order to reduce the effect of wire damage on the earphone receiver, a jack is formed at the position of the earphone receiver according to the invention. The technical scheme of the invention is that the plug-in earphone comprises an earphone receiver, a plug and a stereo transmission wire, wherein the plug of the wire is inserted into the stereo sound source; the wire is divided into a left sound channel signal and a right sound channel signal; the left and the right sound channel signals are respectively connected to a socket with two jacks; each of the jacks has only one signal wire; the two jacks of the wire are inserted into two sockets of a plug base; and the other end plug of the plug base is inserted into the two jacks of the earphone receiver. The plug-in earphone provided by the invention has the benefits that each jack has only one signal wire, so that the jack is relative robust; the earphone receiver and the wire are separated and easy to replace, so that waste is avoided; and as the jack is relative robust and not easy to damage, the earphone receiver can be used longer.

Description

The plug-in type earphone

Technical field

The present invention relates to the earphone that separate with lead in earphone field, particularly receiver.

Background technology

The critical component of earphone is a receiver, and the quality of receiver is determining the acoustical quality of earphone, because current headset earpiece and lead welds together; Earphone is worn on the head, lead is long, can occur unavoidably pullling, and pulls to cause harness damage; The solder joint of most of earphones, particularly earplug is very little; It is good that common people's solder technology is difficult to welding, usually cause after the welding contacting bad, have because scolding tin is inhomogeneous even cause short circuit; What have breaks away from copper-clad plate because of the copper-clad plate of circuit board and the different copper conductor of copper-clad plate that causes of expanded by heating coefficient of base plate plastics, and these all possibly cause receiver to damage.

Summary of the invention

For reducing the influence of harness damage to receiver, the present invention is at two jacks of receiver Position Design.

The technical scheme that the present invention solves its technical problem employing is: the plug-in type earphone is made up of receiver, plug and stereo transmission lead, and lead has a stereo plug, two sockets, and each socket has 2 jacks; Plug is fixed on the pedestal, and the plug two ends pedestal of emerging is hurted sb.'s feelings for avoiding plug, and the plug top is level and smooth; Headset earpiece has 2 jacks.

The plug of lead inserts in the stereo sound source; Lead is divided into left and right sound track signals, and left and right acoustic channels connects a socket respectively, and each socket has 2 jacks, and a jack has only a holding wire; Two jacks of lead insert in two plugs of Plug base; The other end plug of Plug base inserts in two jacks of headset earpiece.

The invention has the beneficial effects as follows: each jack has only a holding wire, and is simple in structure, thus jack can do must be more strong; Headset earpiece is separated with lead, the damage of lead, and perhaps the damage of headset earpiece is independently, damages that part ofly just to change that part ofly, accomplishes to make the best use of everything, and avoids waste; Because jack is more strong, not fragile, no longer need welding, can guarantee the live part of earphone, headset earpiece, more permanent use.

Wherein, 1, receiver, 2, handset jack, 3, plug, 4, plastic base, 5, wire jack, 6, lead, 7, line trap.

Embodiment

The receiver 1 of earphone has two handset jack 2, and plug 3 one ends of plastic base 4 insert the handset jack of earphone, and an end inserts wire jack 5; What lead 6 transmitted is stereophonic signal; Divide left and right acoustic channels, so lead has two pairs of jacks, the stereo line trap 7 of lead is inserted in the jack of sound source.

Claims

1. the plug-in type earphone is made up of receiver, plug and stereo transmission lead, it is characterized in that: lead has a stereo plug, two sockets, and each socket has 2 jacks; Plug is fixed on the pedestal, the plug two ends pedestal of emerging, and the plug top is level and smooth; Headset earpiece has 2 jacks.

2. according to the said plug-in type earphone of claim 1, it is characterized in that: the stereo plug of lead inserts stereo sound source jack; Lead is divided into left and right sound track signals, and left and right acoustic channels connects a socket respectively, and each socket has 2 jacks, and a jack has only a holding wire; Two jacks of lead insert in two plugs of Plug base; The plug other end of Plug base inserts in two jacks of headset earpiece.
