Fig. 1 is a structural principle block diagram of the present invention;
Fig. 2 is signal generating circuit figure;
Fig. 3 is an amplification circuit diagram;
Fig. 4 is sample circuit figure.
The specific embodiment
As shown in Figure 1, the present invention it comprise audio frequency apparatus 1, signal generating circuit 2, amplifying circuit 3 and sample circuit 4.Audio frequency apparatus 1 is connected with sample circuit 4, and signal generating circuit 2 is connected with amplifying circuit 3, and amplifying circuit 3 is connected with test electrode 5 respectively with sample circuit 4.
As shown in Figure 2, described signal generating circuit 2 comprises IC 1 ICL8038, two resistance R a, Rb and capacitor C f; The signal output part SinOut of signal generating circuit links to each other with the signal input part SinOut of amplifying circuit.The effect of signal generating circuit is the sine wave signal that produces in the audiorange.Signal generating circuit also can be substituted by audio frequency apparatus, as computer, palm PC (PDA), smart mobile phone, music-integrating block etc.
As shown in Figure 3, described amplifying circuit 3 comprises operational amplifier IC2uA741 and three resistance R c, Rd, Re; The signal input part SinOut of amplifying circuit links to each other with the signal output part SinOut of signal generating circuit, and the signal output part ACOut of amplifying circuit is connected with test electrode.
As shown in Figure 4, described sample circuit 4 comprises resistance R z; The signal input part ACin of sample circuit links to each other with test electrode, and the signal output part SigOut+ of sample circuit and SigOut-link to each other with negative terminal with the anode of the mike input circuit of audio frequency apparatus respectively.It is to obtain than higher sensitivity because can select a less sampling resistor Rz like this that the signal output part of sample circuit and the anode of audio frequency apparatus mike input circuit are linked to each other with negative terminal.The signal at sample circuit two ends amplified to send into the audio frequency apparatus line input circuit more also be feasible.The audio frequency apparatus that has is palm PC mike input circuit interface independently not for example, can remove the mike of this equipment, and the circuit that was connected mike on the signal output part SigOut+ of sample circuit and SigOut-and the audio frequency apparatus originally is continuous.For mobile phone, removing mike will make the major function of mobile phone lose, can on mobile phone, increase a bluetooth earphone, remove the mike on the bluetooth earphone, the circuit that was connected mike on the signal output part SigOut+ of sample circuit and SigOut-and the bluetooth earphone originally is continuous.Also additionally obtained the mode of a kind of bio-impedance collecting device and audio frequency apparatus wireless connections in this way.Because Bluetooth protocol supports a plurality of equipment to use simultaneously, therefore the bluetooth earphone that links to each other with bio-impedance collecting device does not influence the use of the bluetooth earphone that is used to converse.
