As further improvement of the utility model, also be provided with a microphone on the described multiport chip.

As further improvement of the utility model, also be provided with volume adjuster on the described multiport chip, described volume adjuster is connected with output port, is used for the power of control output end mouth output signal.

As further improvement of the utility model, the number of described volume adjuster is identical with the number of the output port of multiport chip, and each volume adjuster is separate.

The utlity model has following advantage:

1, the utility model has solved the problem that the same time can only a people uses earphone;

2, the utlity model has a microphone, can realize many people's conversations;

3, the utlity model has a plurality of volume adjusters, everyone can regulate volume according to the needs of oneself;

4, the utility model profile is small and exquisite, and is simple in structure.

Description of drawings

Fig. 1 is the structural representation of a kind of multiport earphone of the present utility model.

Fig. 2 is the fundamental diagram of the multiport chip of a kind of multiport earphone of the present utility model.

Embodiment

Below in conjunction with accompanying drawing, specify the utility model.

Principal character of the present utility model is to utilize the multiport chip will be divided into a plurality of output ports from the audio signal of tone frequency channel wire, to reach the effect that many people use earphone to listen to the music simultaneously.

With reference to Fig. 1, it is the structural representation of a kind of multiport earphone of the present utility model.A kind of multiport earphone of the present utility model, comprise a headset plug 102, the tone frequency channel wire 104 that is connected with a headset plug 102, with at least one secondary receiver 106, this multiport earphone also has a multiport chip, and described multiport chip comprises that audio amplification unit that an input port that is connected with tone frequency channel wire 104, one be used for the audio frequency receiving element of received audio signal, one and amplify audio signal, one divide into the frequency unit of different frequency range and the output port 101 of a plurality of output audio signals with audio signal; Wherein, input port, audio frequency receiving element, audio amplification unit and frequency unit are linked in sequence successively, and a plurality of output ports 101 are connected respectively to described frequency unit, and described receiver 106 is plugged on the output port.

In above-mentioned multiport earphone, also be provided with a microphone 103 on the described multiport chip.

In above-mentioned multiport earphone, also be provided with volume adjuster 105 on the described multiport chip, described volume adjuster 105 is connected with output port, is used for the power of control output end mouth output signal.

In above-mentioned multiport earphone, the output port number of the number of described volume adjuster 105 and multiport chip is identical, and each volume adjuster 105 is separate.

With reference to Fig. 1, in actual use, the user inserts audio-visual equipment (such as mobile phone or MP3) interface with the headset plug 102 of the utility model multiport earphone earlier, a people uses in this way, then only need a secondary receiver 106, the multiport chip output mouth 101 that again receiver 106 is directly inserted the utility model multiport earphone gets final product; Many in this way people use, and then need to be equipped with several pairs of receivers 106 more, and the multiport chip output mouth 101 that respectively receiver 106 is inserted the utility model multiport earphone gets final product;
