Description
Technical field
The present invention is specifically related to the parts of stereo communication equipment as the parts of the audio frequency Input/Output Device of computer.
Background technology
Along with the increasingly extensive application of computer, earphone has become one of indispensable audio frequency Input/Output Device of computer.
At present, headphone can be divided into wired earphone and wireless headset.Wired headphone comprises cable plug, connection cable, volume adjuster, microphone and headset main body, and headset main body comprises earphone body and Tou Liang, and the earphone body is divided into left earphone body and right earphone body.Left side earphone body comprises the earphone left shell and is arranged in the earphone left shell and is fixed on left speaker on the earphone left shell, and the right earphone body comprises the earphone right shell body and is arranged in the earphone right shell body and is fixed on right loud speaker on the earphone right shell body.Beam is connected with earphone right shell body slide relative with the earphone left shell respectively, and regulating size, and then the user who is fit to different head dummys uses.Perhaps headset main body comprises left and right sides earphone body, left and right sides support and Tou Liang; Wherein a beam and left and right sides support are slidingly connected respectively, and left and right sides support is rotationally connected with the housing of corresponding earphone body.
The connection cable of headphone mostly is monolateral connection cable greatly, can be described as the external connection line cable, one end of the surrounding layer of this external connection line cable is fixed with plug, the surrounding layer other end is fixed with the plastic clip joint, this clamping head is connected on the housing of left and right sides housing (being assumed to left shell), this external connection line cable has 5 leads, 2 leads wherein are used for outwards carrying Mike's signal, other 3 leads are divided into the left channel signals lead, right-channel signals lead and common conductor, left channel signals lead and common conductor are electrically connected with two terminals of left speaker respectively, be provided with the internal connection line cable between left shell and the right shell body, and this internal connection line cable is the inner process of beam from the beginning, the internal connection line cable has 2 leads, one end of 2 leads is electrically connected with two terminals of right loud speaker respectively, the other end of a lead in 2 leads is electrically connected with the right-channel signals lead of external connection line cable, and the other end of another root lead in 2 leads is electrically connected with the common conductor of External cable.
Microphone is divided into shank type microphone and the two kinds of forms of microphone that are arranged on the connection cable.For the consideration of ease of use, the most headphone that is used for computer adopts the shank type microphone.The shank type microphone is arranged on the earphone case that is connected with the external connection line cable, the shank type microphone mainly is divided into two types, a kind of is the free end away from earphone case that the microphone pick-up is arranged on handle, to obtain best pickup effect, this moment, the holding wire of microphone was placed in the handle, and handle plays the microphone pick-up and supports and positioning action; Another kind is that microphone is arranged on the headset main body, and the microphone handle of this moment is hollow conduit, is used for the sound collecting that the user sends is conducted to microphone pick-up place.
For the user can regulate volume easily, the headphone that is used for computer also is provided with volume adjustment device usually, and this device can be arranged on the external connection line cable, also can be arranged on the earphone case that is connected with the external connection line cable.
For the headphone that is used for computer, headset main body is is wherein worn and torn less and stressed less so its useful life is longer in use, belongs to non-damageable device; And devices such as microphone handle and volume adjuster are because of need adjusting continually in use, damage when big stressed, the external connection line cable of wired earphone because of pull, bending etc. is also fragile, the former capital belongs to flimsy device; The earphone damage of the overwhelming majority is all damaged by this part consumable accessory and causes.On the other hand, with regard to cost, device cost such as non-damageable parts such as loud speaker, a beam are higher relatively, and costs such as consumable accessory such as volume by-pass cock, microphone, external connection line cable are relatively low.The present headphone that is used for computer is the integrated design, its maintenance difficulty of back is bigger because consumable accessorys such as volume by-pass cock, microphone, connecting line are damaged like this, cause a lot of earphones when the high value device can also continue to use, just to be scrapped, cause bigger economic loss, thereby use cost is higher.Especially change frequent place at earphones such as Internet bars, loss is just bigger.
Chinese patent literature CN2143035Y discloses a kind of discrete earphone with socket, and this earphone belongs to the earphone of bilateral connection cable.This earphone comprises that three plugs and this three plugs are linked to each other by lead, also comprise socket, shell and sounding body, can conveniently revise or change when in use damaging, but its scheme is not suitable at present the generally headphone that is used for computer that comprises microphone and volume adjuster of employing by three continuous plugs of lead.
Chinese patent literature CN201054781Y discloses a kind of removable headphone, and this earphone belongs to the earphone of monolateral connection cable.This earphone comprises audio connecting cord, left and right sides ear tube, ear tube bonnet, machine folder and the audio frequency external connection that has joint.The audio connecting cord of the audio frequency external connection of this earphone and left and right sides ear tube can be for convenience detach, need not the just detachable maintenance of specific purpose tool, can improve useful life.But this earphone in use, because the audio frequency external connection is pullled through regular meeting, the frequent stressed audio frequency external connection that causes very easily separates with left and right sides ear tube, causes the inconvenience of use.This scheme is not suitable at present the generally computer headphone that comprises microphone and volume adjuster of employing simultaneously.
