Problems solved by technology

[0002] The student earphone microphone used in the voice teaching equipment and the university computer room equipment is connected to the equipment by wired connection. The earphone microphone in the student unit is hung on the seat, and the students in the school share the earphone microphone in the classroom. The curiosity of the engineering students is strong. The earphone microphone is used as the object of fiddling in class, resulting in a high rate of damage to the earphone microphone of students. In addition, it is difficult to manage, and the loss phenomenon is serious, which directly affects the safe operation of the voice teaching equipment, and thus affects the normal teaching order. Increased the management difficulties of large-scale use of language labs, high operating costs, resulting in many colleges and universities teaching foreign language listening courses can not be guaranteed in the language room
[0003] In addition, the earphone microphones in computer rooms in universities have the same problem, and the phenomenon of damage and loss is serious, so that many computer rooms dare not install earphone microphones, or use the method of students to bring their own earphone microphones for independent learning, etc.
When students bring their own earphones and microphones, the socket on the PC is seriously damaged due to frequent plugging and pulling out of the plug.

Abstract

The earphone signal is loaded into the earphone signal emission coil to generate audio magnetic field, which is received by earphone signal receiving coil in earphone signal amplifying circuit and is transformed into audio voltage signal. Then the signal is loaded into amplifying circuit to drive earphone. Meanwhile the mic in the mic-earphone amplifying circuit picks up the speech of student and sends it into amplifier of mic. After amplifying, it drives mic signal emission coil to generate audio magnetic field. The mic signal is received by mic signal reception coil and is transformed into audio signal of mic that is loaded into the mic plug in socket.
