Multiplex earphone

Technical field

The utility model relates to a kind of earphone, particularly relates to a kind of multiplex earphone.

Background technology

Mobile phone or other audio frequency apparatuses much all have earphone interface, the multiplex special purpose interface of earphone interface or the 2.5mm interface of early stage mobile phone, handset earphone also is mainly used in call function, now increasing music or multimedia feature handset select the 3.5mm standard interface as earphone interface, the user can select on the market high-quality 3.5mm stereophone like this, and the user also can be input to audio frequency power amplifier or other stereo sets to mobile phone as a source of sound by earphone interface.3.5mm the earphone of standard has dividing of 3 pin and 4 pin on pin number, the mechanical dimension of these two kinds of headset plugs is the same.4 pin 3.5mm earphones are usually used in the equipment such as mobile phone, and it is microphone that a newly-increased pin is commonly defined as Mike, but two kinds of standards are arranged in the definition of Mike's pin, are respectively open mobile-terminal platform standard and North America working standard.These two kinds of standards are consistent in the definition of plug the first pin 1 and the second pin 2, but the 3rd pin 3 and the 4th pin 4 are just in time opposite in the definition on Mike and ground, the former is that the 3rd pin 3 is that Mike, the 4th pin 4 are ground, and the latter to be the 3rd pin 3 be ground, the 4th pin 4 are Mikes.

Below as can be known, existing earphone can not be common on different mobile phones, adaptability is not strong, after the not corresponding earphone of mobile phone and model connects, easily cause audio frequency dysfunction, cause sound to diminish, can't hear the problems such as sound, and to use the different classes of mobile phone of plug pin need adopt the earphone of different model, not only be inconvenient to carry, and increase user's use cost.

The utility model content

Based on this, be necessary the problem for the shortcoming of prior art, the utility model provides multiplex earphone a kind of and that mobile phone different model is connected.

Based on this, the utility model provides a kind of multiplex earphone, comprise L channel loudspeaker, R channel loudspeaker, Mike, earphone interface and diverter switch, described L channel loudspeaker and R channel loudspeaker are electrically connected on earphone interface, described earphone interface is electrically connected by diverter switch and Mike, thereby thereby the definition of change Mike's pin adapts to the audio frequency link of various criterion.

Therein in embodiment, described earphone interface comprises the first pin, the second pin, the 3rd pin and the 4th pin, the first pin and the second pin are electrically connected with the input of L channel loudspeaker, R channel loudspeaker respectively, and the 3rd pin and the 4th pin are electrically connected on diverter switch.

In embodiment, described L channel loudspeaker, R channel loudspeaker and Mike's earth terminal is electrically connected on diverter switch respectively therein.

Therein in embodiment, described diverter switch comprises first interface, the second interface, the 3rd interface, the 4th interface and the 5th interface, described first interface is electrically connected on the L channel loudspeaker, described the second interface is electrically connected on the R channel loudspeaker, described the 3rd interface is electrically connected on the 3rd pin of earphone interface, the 4th interface is electrically connected on the 4th pin of earphone interface, and the 3rd interface and the 5th interface electrically conduct.

Above-mentioned multiplex earphone can be connected with the mobile phone of different model multiplex earphone by regulating diverter switch, reaches the multiplex purpose of earphone, and strong adaptability is easy to carry, reduces the cost that the consumer uses earphone.

Description of drawings

Fig. 1 is that the multiplex earphone of the utility model uses connection diagram when opening the mobile-terminal platform standard.

Fig. 2 is the connection diagram that the multiplex earphone of the utility model uses the North America working standard.

Below the explanation of the utility model parts sign flag:

L channel loudspeaker 10, R channel loudspeaker 20, Mike 30, earphone interface 40, the first pin 41, the second pin 42, the 3rd pin 43, the 4th pin 44, diverter switch 50, first interface 50, the second interface 52, the 3rd interface 53, the 4th interface 54, the 5th interface 55.

Embodiment

For further understanding feature of the present utility model, technological means and the specific purposes that reach, function, resolve advantage of the present utility model and spirit, by below in conjunction with accompanying drawing and embodiment, detailed description of the present utility model being further understood.

See also Fig. 1, the multiplex earphone of the utility model, comprise L channel loudspeaker 10, R channel loudspeaker 20, Mike 30, earphone interface 40 and diverter switch 50, described L channel loudspeaker 10 and R channel loudspeaker 20 are electrically connected on earphone interface 40, and described earphone interface 40 is electrically connected with Mike 30 by diverter switch 50.

Described earphone interface 40 comprises the first pin 41, the second pin 42, the 3rd pin 43 and the 4th pin 44, and wherein the first pin 41 and the second pin 42 are all the audio frequency pin, and the input with L channel loudspeaker 10, R channel loudspeaker 20 is electrically connected respectively.The 3rd pin 43 and the 4th pin 44 are electrically connected on diverter switch 50.
