1, handle group mode Handset Group: handle and hands-free speaker be sounding simultaneously, has only the micphone of handle can receive sound;
2, headphone set pattern Headset Group: earphone and hands-free speaker be sounding simultaneously, has only the micphone of earphone can receive sound;
3, ears wheat pattern Double Headset: the speaker of earphone and handle can both sounding, has only the micphone of earphone can receive sound.
As shown in Figure 1, modal scheme is in phone: each call mode all needs an audio coding/decoding device (audio codec) and corresponding sound signal amplifier (amplifier) to realize that complete AD/DA transforms and voice signal amplifies.Generally will use 3 groups of audio coding/decoding devices (audio codec), 3 speaker sound signal amplifiers (speaker amlifier) and 3 microphone voice signal amplifiers (micphone amplifier) are realized 6 kinds of call modes of demand.
The utility model content
The purpose of this utility model is to provide a kind of chromacoder of realizing multiple call mode with the less hardware expense.
A kind of chromacoder of realizing multiple call mode, it is characterized in that: mainly comprise a DSP modular converter, one audio coding/decoding device, one three tunnel final election switch, one three the tunnel singly selects switch, three speaker sound signal amplifiers and a microphone voice signal amplifier, input and output voice data through the DSP module processing accesses to the audio coding/decoding device, three tunnel final election switches are received in the DA output of this audio coding/decoding device, the AD of this audio coding/decoding device input is connected in the output of microphone voice signal amplifier, and the input of microphone voice signal amplifier is received three the tunnel and singly selected on the switch;
The A node of this three tunnel final elections switch is connected in the input of the first speaker sound signal amplifier, and the output of this first speaker sound signal amplifier connects the loudspeaker of hands-free mode; The B node of this three tunnel final elections switch is connected in the input of the second speaker sound signal amplifier, and the output of this second speaker sound signal amplifier connects the loudspeaker of handle pattern; The C node of this three tunnel final elections switch is connected in the input of the 3rd speaker sound signal amplifier, and the output of the 3rd speaker sound signal amplifier connects the loudspeaker of headset pattern;
This three the tunnel singly selects the A node of switch to connect the microphone of hands-free mode, and this three the tunnel singly selects the B node of switch to connect the microphone of handle pattern, and this three the tunnel singly selects the C node of switch to connect the microphone of headset pattern;
When realizing hands-free mode, control the A node closure that three tunnel final election switches and three tunnel singly select switch by control program; When realizing the handle pattern, control the B node closure that three tunnel final election switches and three tunnel singly select switch by control program; When realizing the headset pattern, control the C node closure that three tunnel final election switches and three tunnel singly select switch by control program; When realizing the handle group mode, control A and the B node closure of three tunnel final election switches by control program, the three tunnel singly select the B node closure of switch; When realizing the headphone set pattern, control A and the C node closure of three tunnel final election switches by control program, the three tunnel singly select the C node closure of switch; When realizing ears wheat pattern, control B and the C node closure of three tunnel final election switches by control program, the three tunnel singly select the C node closure of switch.
After having adopted the technical solution of the utility model, only use 1 group of audio coding/decoding device (audio codec), 3 speaker sound signal amplifiers (speaker amplifier) and 1 microphone voice signal amplifier (micphone amplifier) just can be realized 6 kinds of call modes, have saved hardware resource greatly.
