Detailed description of the invention
Portable wireless electronic stethoscope, comprises an auscultation main frame and N number of receiving system, N >=2, as shown in Figure 1.
As shown in Figure 2, described auscultation main frame is sticked at human body surface, and it is integrated with stethoscope head, the pick up be connected with stethoscope head, digital audio amplifier integrated circuit and high frequency power amplification emissioning circuit.The display circuit for showing tranmitting frequency is provided with in described auscultation main frame.
As shown in Figure 3, described N number of receiving system carries out wireless connections with auscultation main frame respectively, and it is integrated with high frequency power and amplifies receiving circuit, digital audio amplifier integrated circuit, audio output circuit and audio output terminal equipment.The display circuit for showing receive frequency and the memory circuit for stored audio signal is also provided with in described receiving system.
Auscultation main frame as shown in Figure 4, its operation principle is: when stethoscope head is near human heart auscultation position, hear sounds is delivered on pick up through stethoscope module, pick up is converted to audio signal heartbeat sound, audio signal carries out Analog-digital Converter through capacitance resistance coupled transfer to digital audio amplifier integrated circuit I the 3rd foot, amplify, filtering, de-noising, shaping, then exported by outfan 5 foot, and then the audio signal exported is input to high frequency power amplification emissioning circuit through inductance L 1, go out finally by antenna transmission, show tranmitting frequency by display circuit simultaneously.
Receiving system as shown in Figure 5, its operation principle is: the high frequency radio signal received through antenna carries out output audio signal after frequency-selecting, amplification, modulation /demodulation, the audio signal exported passes through electric capacity, resistively couple amplifies to digital audio amplifier integrated circuit II, finally exported by 5 feet and by speaker audio electrical signal converted to sound and send the sound, simultaneously by display circuit display receive frequency and volume.
