Description

A kind of earphone for mobile phone and microphone connecting line

Technical field

The utility model relates to a kind of mobile phone connecting line, and specifically, the utility model relates to a kind of earphone for mobile phone and microphone connecting line.

Background technology

Along with the extensive of smart mobile phone popularized, mobile phone can provide how modish, practical application for user.Particularly, increasing smart phone user, utilizes mobile phone carry out network singing or record personal monograph, sends on the Internet.

But, in actual use, due to the microphone of embedded in mobile phone or the external headset of giving as an addition, main purpose of design is to provide the use of speech communication, so, the microphone that it is built-in or external headset Hz-KHz are narrow, dynamic range is little, distortion is large, records the wide audio signal weak effect of Hz-KHz, can not meet the requirement of user to recording quality.For this reason, a lot of users think the external special high-quality microphone for recording, and improve whole recording result.

As shown in Figure 1A, Figure 1B, with the mobile phone of external headset, its earphone and microphone share same interface, are called for short earphone microphone interface.This earphone microphone interface is the female seat of diameter 3.5mm, it has 4 contact points: earphone L channel, earphone R channel, ground wire, microphone signal, its difference is, different mobile phone manufacturers is different to the position definition of ground wire contact point and microphone signal contact point.

As shown in Fig. 2 A, Fig. 2 B, the male plug that the plug that common stereophone is used is diameter 3.5mm, it has 3 contact points: earphone L channel, earphone R channel, ground wire; And what also use with the stereophone plug (as shown in Fig. 3, Fig. 4, Fig. 5) of microphone is the male plug that diameter is 3.5mm, there are 4 contact points: earphone L channel, earphone R channel, ground wire, microphone signal.Due to stereophone or with the plug of stereophone and the earphone microphone interface of mobile phone of microphone, match, so, stereophone or can directly insert in the earphone microphone interface of mobile phone with the stereophone of microphone.

And, be used for specially carrying out OK a karaoke club 0K performance or recording recording microphone wind (for earphone on microphone difference, here by the moving-coil for recording, capacitance microphone is called recording microphone wind), as Fig. 6 A, shown in Fig. 6 B, the plug of its use is the plug of direct 6.3mm, the interface matching with it is the XLR male terminal of industrial standard, it has 3 contact points: ground wire, 2 microphone signals, completely different from the earphone microphone interface structure of mobile phone, from physical diameter and signal definition, the 4 contact point diameter 3.5mm Interface Matching that all cannot use with mobile phone, so, recording microphone wind can not directly insert the earphone microphone interface of mobile phone.If user wants the relative more outstanding recording microphone wind of external sound quality on mobile phone, the recording effect of having realized, at present ready-made product and technology have no idea to realize.

In addition, when smart mobile phone has detected plug and is inserted into earphone microphone interface, can, by the loud speaker automatic mute of embedded in mobile phone, voice output be switched on earphone.And when network is sung or recorded special edition, user needs to monitor accompaniment by voice output, therefore, when connecting microphone, also need earphone gang socket to offer user, connect outside earphone, the monitoring of accompanying, this is also that existing product and technology cannot realize the application that external recording microphone carries out high-quality recording.Existing product and technology, user can only be on mobile phone the subsidiary headset of connecting with external mobile phone.

Utility model content

In view of the foregoing, the purpose of this utility model is to provide a kind of earphone for mobile phone and microphone connecting line, this connecting line can be connected to common earphone and recording microphone wind on mobile phone and use simultaneously, by the powerful multimedia function of mobile phone, the OK a karaoke club 0K that carries out high tone quality sings, network is sung or high-quality recording.

For achieving the above object, the utility model is by the following technical solutions: a kind of earphone for mobile phone and microphone connecting line, and it comprises that diameter is earphone socket and the microphone plug that the headset plug with 4 contact points, signal separation unit, the diameter of 3.5mm is 3.5mm;

The headset plug with 4 contact points that one end of connecting line is 3.5mm with described diameter is connected, and this headset plug mates with the earphone microphone interface of mobile phone;

Signal separation unit be provided with one on connecting line described in is separated ground wire, earphone left channel signals line, earphone right-channel signals line, microphone signal line in this signal separation unit;

In described signal separation unit, the earphone socket that described in, diameter is 3.5mm is also installed, ground wire, earphone left channel signals line, earphone right-channel signals line are connected with this earphone socket; Ground wire is connected with described microphone plug with microphone signal line.

The utility model also comprises a signal shift switch for earphone and the microphone connecting line of mobile phone, and this signal shift switch is arranged in signal separation unit, for according to different mobile phone earphone microphone interfaces, the position between microphone signal line and ground wire is switched.
