This utility model provides teaching stethoscope, solves the technical problem that existing teaching stethoscope cannot carry out long-range use.
For solving the problems of the technologies described above, this utility model adopts following technical scheme:
Teaching stethoscope, comprise auscultation head and ear piece, described auscultation head and ear piece connection rubber tube respectively, described teaching stethoscope also comprises sound transducer, micro-control unit, power amplifier, audio-frequency module, wireless transport module and communication telephone, described sound transducer is located in the sebific duct be connected with auscultation head and the acoustical signal of auscultation head is converted into analogue signal, sound transducer connects the input interface input analogue signal of audio-frequency module, audio-frequency module is connected with micro-control unit and analogue signal is stored, wireless transport module is connected with micro-control unit analogue signal is carried out wireless transmission, one end of described power amplifier is connected with the output pin of micro-control unit amplifies analogue signal, the other end of power amplifier connects ear piece.
Preferred technical scheme, described audio-frequency module comprises signal amplifier, analog-digital converter and digital to analog converter, sound transducer is connected with signal amplifier, signal amplifier and analog-digital converter, analog-digital converter is connected with micro-control unit, the input of digital to analog converter is connected with micro-control unit, and the outfan of digital to analog converter is connected with power amplifier.
Preferred technical scheme, described wireless transport module has two switches, comprises signal transmit button and Signal reception switch.
Preferred technical scheme, described auscultation head and sebific duct are threaded, and are also provided with sealing adhesive plaster between auscultation head and sebific duct.
The beneficial effects of the utility model are:
By arranging sound transducer, the acoustical signal of auscultation head is converted into analogue signal, analogue signal directly exports ear piece to by audio-frequency module and power amplifier and studies and judges the state of an illness for doctor, on the other hand, by arranging the micro-control unit be connected with audio-frequency module, just can by analog signal transmission on long-range same model teaching stethoscope by micro-control unit wireless transport module, the function realizing online teaching is listened to for long-range student, student can also be conversed online by communication telephone and teacher doctor, better can solve the knotty problem in remote teaching process, improve remote teaching quality.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, this utility model is described further:
Fig. 1 is the structural representation of this utility model teaching stethoscope.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.
As shown in Figure 1, teaching stethoscope, comprise auscultation head 1 and ear piece 2, auscultation head 1 and ear piece 2 connection rubber tube 12 respectively, auscultation head 1 and sebific duct 12 are threaded, and auscultation head 1 sound for transmission channel, is also provided with sealing adhesive plaster between auscultation head 1 and sebific duct 12 with pipe in sebific duct 12, the air-tightness of pipe in sebific duct 12 can be improved, thus improve auscultation head 1 sound conduction quality.
Teaching stethoscope also comprises sound transducer 3, micro-control unit 4, power amplifier 5, audio-frequency module 6, wireless transport module 7 and communication telephone 8, sound transducer 3 is located in the sebific duct 12 be connected with auscultation head 1 and the acoustical signal of auscultation head 1 is converted into analogue signal, sound transducer 3 connects the input interface input analogue signal of audio-frequency module 6, audio-frequency module 6 is connected with micro-control unit 4 and analogue signal is stored, wireless transport module 7 is connected with micro-control unit 4 analogue signal is carried out wireless transmission, power amplifier 5 is located on micro-control unit 4, one end of power amplifier 5 is connected with the output pin of micro-control unit 4 amplifies analogue signal, the other end of power amplifier 5 connects ear piece 2, moving-coil is provided with in ear piece 2, analogue signal is inputted moving-coil by being connected with the moving-coil of ear piece 2 with pipe in the sebific duct on ear piece 2 by the lead-in wire of power amplifier 5, thus analogue signal is converted into sound and sends from ear piece 2.
