Description

Two-channel Earphone for two persons at same time

Technical field

The utility model relates to a kind of earphone, particularly relates to a kind of two-channel Earphone for two persons at same time.

Background technology

The application of earphone has had the history of many decades, and visiing sub-power is earphone company with the longest history, foundes the earliest In nineteen twenty-four.Nineteen thirty-seven visits sub-power and takes the lead in have developed the secondary moving coil earphone DT48 that beats the world, thence into high-fidelity Earphone field.DT is Dynamic Telephone, i.e. the abbreviation of " power phone ".When just inventing DT48, " earphone " (headphone) this word there is not yet, and Mr. Bai Ya is referred to as " power phone " the invention of oneself, and this monogram of DT is just Continued to use always.

Earphone mainly includes moving-coil (Dynamic) earphone and the big class of electrostatic (Electrostatic) earphone two, although remove this Several earphones such as magnetic-type earphone such as Shang You outside two classes, but or be eliminated or for professional purpose market share amount pole Few.Moving-coil earphone principle: the earphone earplug of most at present (about more than 99%) all belongs to this type of, and principle is similar to common sound Case, the coil being in permanent magnetic field is connected with vibrating diaphragm, and coil drives vibrating diaphragm sounding under signal code driving, and moving coil earphone is Earphone the most common, modal, its driver element is basically a small-sized moving-coil speaker, by being in permanent magnetic field Voice coil loudspeaker voice coil drive the diaphragm oscillations that is attached thereto.Moving coil earphone efficiency comparison is high, mostly can drive for the earphone output on sound equipment Dynamic and reliability and durability.

With the raising of scientific and technological development and people's application demand, double earphone arises at the historic moment, and double earphone is exactly Two set of headphones are connected in parallel on a headset plug, thus meet two people and use a player simultaneously Demand.But this double earphone is all mono headset, it is impossible to realize the broadcasting of two-channel, reduces the use feeling of user It is subject to, on the premise of the single earphone overwhelming majority on existing market is two-channel sterearphone, this double monophone Road earphone also gradually cannot meet demand and the hearing enjoying of user.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of simple in construction, low cost, alliteration applied widely Road Earphone for two persons at same time.

The utility model two-channel Earphone for two persons at same time, including the first earphone, the second earphone and plug, the first headset left channel The ground wire of ground wire and R channel is connected with the ground contact point of plug, and the audio frequency of the first headset left channel receives line and the second earphone The audio frequency of L channel receives line and is all connected with the first audio frequency contact point of plug, the audio frequency of the R channel of the first earphone receive line with The audio frequency of the second earphone R channel receives line and is all connected with the second audio frequency contact point of plug.

The utility model two-channel Earphone for two persons at same time, wherein said first earphone and the second earphone use different outside face Look.

The utility model two-channel Earphone for two persons at same time, wherein said plug is three pin plug or Four wire plug.

The utility model two-channel Earphone for two persons at same time, the call contact point control with Answer Key respectively of wherein said Four wire plug The signal transmission end of end processed and microphone connects, the ground contact point of Four wire plug respectively with the earth terminal of Answer Key and connecing of microphone Ground end connects.

The utility model two-channel Earphone for two persons at same time, wherein said audio frequency receives a length of 30cm～150cm of line.

The utility model two-channel Earphone for two persons at same time difference from prior art is: while the utility model is on plug Connect two secondary two-channel sterearphones, normal stereo earphone is divided into two, be that two users listen two-channel to stand simultaneously The broadcast of body sound provides conveniently.Two secondary two-channel sterearphones are connected on plug with identical connected mode, two uses Person can not affect the extraneous and non-interfering same sound listening broadcasting in player simultaneously.First earphone and the second ear Machine uses different exterior color, it is simple to difference, it is to avoid occur situation about obscuring during use.Plug can according to circumstances select three lines Plug or Four wire plug, three pin plug is for common stereo player；Four wire plug also respectively with Answer Key and microphone Connecting, having the function receiving calls and conversing, Four wire plug is for carrying out the mobile phone of played in stereo.According to different Equipment choice, with the earphone of corresponding plug, is greatly expanded range.

Below in conjunction with the accompanying drawings the utility model two-channel Earphone for two persons at same time is described further.
