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 object of the present invention is to provide an audio magnetic conduction connection method and device thereof between an earphone microphone and voice teaching equipment and university computer room equipment. The earphone signal is added to the earphone signal transmitting coil in the audio magnetic guide to generate the earphone signal audio frequency. Magnetic field, headphone signal audio magnetic field is received by the headphone signal receiving coil in the microphone headphone signal receiving amplification part, and converted into an audio voltage signal, which is added to the headphone drive amplifier for power amplification to drive the headphone; at the same time, the microphone headphone signal receiving amplification part The built-in microphone picks up the student's speech, converts it into an electrical signal, and sends it to the microphone amplifier. After amplification, it drives the microphone signal transmitting coil to generate the microphone signal audio magnetic field. The microphone signal audio magnetic field is absorbed by the microphone signal receiving coil in the audio magnetic guide. Receive and convert it into a microphone audio signal, and add it to the microphone input socket on the student's desk in the language room to complete the microphone signal transmission.

Description

Technical field [0001] The invention relates to voice teaching equipment and university computer room equipment, in particular to an audio magnetic permeance connection method and device between earphone microphone and voice teaching equipment and university computer room equipment. Background technique [0002] The voice teaching equipment and the student headset microphone used in the university computer room equipment are connected to the equipment by wired connection. The headset microphone in the student unit is hung on the seat. The students in the school share the headset microphone in the classroom. The engineering students are very curious. The earphone microphone is used as the object of fiddling in class, resulting in an extremely high rate of damage to the student’s earphone microphone. In addition to the difficulty of management, the loss phenomenon is more serious, which directly affects the safe operation of voice teaching equipment, and affects the normal teaching...
