Background technology
Electronic product becomes the necessary article in people's daily life gradually at present, a lot of digital products are all furnished with supporting with it earphone, for example mobile phone, mp3, PDA etc., the application function different according to earphone, the standard that its specification standard is ununified, cause like this user in the time using different electronic products, may need to use different earphones, bring in the use trouble so not only to user but also need again user to increase an extra money of opening, especially to audiophile, hundreds of of extra increase even several thousand earphone is the factor that must consider, just because of this, start in the world to have unified gradually earphone standard, the earphone of 3.5mm jack and 2.5mm jack standard has occupied 90% market at present, become the gb specification in earphone market.
Even but for the earphone of current most popular 3.5mm/2.5mm jack, the terminal definition of the earphone socket of distinct device also may be different, for instance, be both the four-part form earphone (take handset earphone as example) of standard 3.5mm/2.5mm jack and three-section earphone (take mp3 earphone as example, with reference to Fig. 2), with reference to Fig. 1, on the plug of four-part form earphone, include ground wire terminal A, mic terminal B, R channel terminal C and L channel terminal D, with reference to Fig. 2, on three-section earphone plug, include ground wire terminal a, R channel terminal c and L channel terminal d, contrast two figure, the length of ground wire terminal a is the length sum of ground wire terminal A and mic terminal B.In the time that handset earphone is inserted on mp3 earphone socket, the mic terminal B part that what the earth wire contact on socket touched is on handset earphone plug but not ground wire terminal A, therefore this has just caused the problem that handset earphone cannot normally use on mp3, although mp3 earphone can be inserted on mobile phone and listen to the music, obviously cannot realize its call function.
In addition some are adopted the electronic equipment (for example iphone) of the four-part form socket of non-GB definition, because putting in order of its socket contact is inconsistent, for example A part is defined as mic terminal by it, B part is defined as ground wire terminal, and this standard four-part form earphone just cannot use on such equipment so.。
