Embodiment
In order to make technical scheme of the present invention set forth more clear clearly,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that how herein description and accompanying drawing statement only realize the present invention in order to explanation, is not to be used to limit the present invention.
Usually the audio treatment unit of portable terminal all can have the output channel more than 2 or 2, and when the actual design of portable terminal, but mostly just only uses wherein 1.Fig. 1 is the audio frequency export structure of plurality of earphone jack music phone in the prior art, earphone interface 104 and earphone interface 105 are connected in parallel on the audio output circuit unit 103, by CPU 101 control audio treatment circuits Unit 102, export audio frequency to audio output circuit Unit 103, output to the earphone that is connected separately by earphone interface 104 with earphone interface 105 again.
The present invention is then by disposing corresponding audio output unit and earphone interface for each output channel, the multichannel output channel is outputed to different earphone interfaces respectively, thereby realize the plurality of earphone passage, meanwhile, the user can send instruction to the audio frequency control unit by software, and the output of control audio processing unit and audio output unit comes each output channel is carried out personal settings.
Be the embodiment during according to the portable terminal that the invention provides 2 earphone channel interfaces as shown in Figure 2, this portable terminal comprises central microprocessing unit 201, audio treatment unit 202, audio output unit 203.A and audio output unit 203.B, earphone interface A and earphone interface B, audio frequency control unit 204 and Mac circuit unit 206.Audio treatment unit 202 has two independently audio frequency output channel 202.A and 202.B, and audio signal is handled after export earphone interface A and earphone interface B to by the audio output unit 203 of each earphone passage through audio treatment unit 202.
Specifically, for first earphone passage, audio signal is after audio treatment unit 202 is handled, export the audio output unit 203.A of this earphone passage to by first output channel 202.A of audio treatment unit 202, again by its audio signal output that will comprise left and right acoustic channels to earphone interface A; For second earphone passage, audio signal is after audio treatment unit 202 is handled, export the audio output unit 203.B of this earphone passage to by second output channel 202.B of audio treatment unit 202, again by its audio signal output that will comprise left and right acoustic channels to earphone interface B, like this, two people use earphone separately to insert earphone interface A and earphone interface B respectively, just can enjoy high-quality music simultaneously.
If the user wants music effect is separately regulated, only need to send instruction to central microprocessing unit 201 by software operation audio frequency control unit 204, command central microprocessing unit 201 to adjust the relevant parameter of audio treatment unit 202, just can realize independent regulation, thereby satisfy two different listeners' individual demand simultaneously the on off operating mode of volume, audio, special-effect and each voice-grade channel of two-way audio signal etc.
In addition, the user can also use the earphone with Mike's function to realize the function of audio frequency input.In this embodiment, the earphone interface A of two-way earphone passage and earphone interface B are circular holes, be distributed in the same side of portable terminal, and all comprise independently audio input channel 206.A and audio input channel 206.B separately, their shared same Mike's input circuit unit 206 are transported to audio treatment unit 202 to audio input signal.
And be embodiment during according to the portable terminal that the invention provides 3 earphone channel interfaces as shown in Figure 3, this portable terminal comprises central microprocessing unit 301,302,3 audio output unit 303.A303.B of audio treatment unit and 303.C, 3 earphone interface A, B and C, audio frequency control unit 304 and Mac circuit unit 306.Audio treatment unit 302 has three independently audio frequency output channel 302.A, 302.B and 302.C, and audio signal is handled after export earphone interface A, earphone interface B and earphone interface C to by the audio output unit 303 of each earphone passage through audio treatment unit 302.
Specifically, for first earphone passage, audio signal is after audio treatment unit 302 is handled, export the audio output unit 303.A of this earphone passage to by first output channel 302.A of audio treatment unit 302, again by its audio signal output that will comprise left and right acoustic channels to earphone interface A; For second earphone passage, audio signal is after audio treatment unit 302 is handled, export the audio output unit 303.B of this earphone passage to by second output channel 302.B of audio treatment unit 302, again by its audio signal output that will comprise left and right acoustic channels to earphone interface B; For the 3rd earphone passage, audio signal is after audio treatment unit 302 is handled, export the audio output unit 303.C of this earphone passage to by the 3rd output channel 302.C of audio treatment unit 302, again by its audio signal output that will comprise left and right acoustic channels to earphone interface C, like this, three people use earphone separately to insert earphone interface A, earphone interface B and earphone interface C respectively, just can enjoy high-quality music simultaneously.
If the user wants music effect is separately regulated, only need to send instruction to central microprocessing unit 301 by software operation audio frequency control unit 304, command central microprocessing unit 301 to adjust the relevant parameter of audio treatment unit 302, just can realize independent regulation, thereby satisfy three different listeners' individual demand simultaneously the on off operating mode of volume, audio, special-effect and each voice-grade channel of three tunnel audio signals etc.
In addition, the user can also use the earphone with Mike's function to realize the function of audio frequency input.In this embodiment, the earphone interface A of three road earphone passages, earphone interface B and earphone interface C are square holes, be distributed in the not homonymy of portable terminal respectively, and all comprise independently audio input channel 306.A, audio input channel 206.B and audio input channel 206.C separately, their shared same Mike's input circuit unit 306 are transported to audio treatment unit 302 to audio input signal.
In like manner as can be known, if we want to realize 4 earphones even the embodiment of plurality of earphone more, also only need the corresponding output channel (comprising audio output unit and earphone interface) that increases, use to have the audio treatment unit of corresponding output channel number at least, and the audio frequency control unit is carried out corresponding setting can obtain.
