The present invention is an e-learning A / V system capable of wireless microphone send / receive function, wireless remote control and laser pointer function, and interface with PC to control GUI method. It is composed of wireless microphone transmission and reception function and wireless remote control unit to enable low voice lecture and remote control of this system.Echo function of stereo and mono conversion function for stereoscopic sound and input / output terminal and remote of many external audio devices Diversify audio functions such as telephone input / output unit that enables educational effect through telephone conversation with external lecturers, and utilizes educational materials on cyber via internet immediately and three-dimensionally without limitation of time and space. Play, save, transfer, and enable cyber distance learning. O functions and the integration of the PC, relates to the operation of the overall function of the system to the e-learning A / V system the key pad of the overall functions configured on the UI to be formed of a GUI system.

Conventional audio equipment and wireless microphone transmitters are not only separated into a separate system from a PC, but also wireless microphone transmitters are separated from a transmitter and a receiver, so that transmission and reception are opposite to each other. If you want to amplify it and output it to the speaker, you need to install a separate amplifier. If you attach it to the wall to use the wireless microphone in the classroom, you must make a separate case. Not only did it become practical, but it also cost double the expense.

In other words, in the classroom classrooms up to now, the classroom has not been equipped with a stereoscopic audio system or the audio system is not equipped, so that the accumulation of fatigue due to continuous teaching and the audio system are provided through the direct training of teachers. Even if it is a separate function as well as a separate function from PC, it was insufficient to expect the effect of education for e-learning environment.

The present invention for solving the above-mentioned shortcomings is based on the teacher's request, the storage or transmission of textbooks over time and space for voice teaching materials or video teaching materials stored on a PC, and educational materials in cyber via camera images or the Internet. In order to enable immediate and lively use, reduce the fatigue of teachers accumulated through direct voice training or non-scientific teaching materials, and to freely use the teaching materials in the classroom. Of course, the wireless remote control is also possible, so that the lessons can be made smoothly with a low voice, and the laser pointer configured in the wireless remote controller can also function as a simple tool. If you have a foreign language or other subjects Configure memory ICs that can be recorded so that you can review them anywhere, anytime.

In other words, the present invention provides an interface between the system and the PC and utilizes or stores the wireless transmission / reception microphone function and a plurality of external audio teaching input units, a plurality of audio output units, a wireless remote control unit, a laser pointer function, and teaching materials. In addition, there is a window graphic part for controlling the system such as real-time transmission, so that it can be used as a system integrated with a PC, and in the case of subjects requiring repetitive training such as foreign languages, it is automatically repeated infinitely until released by one operation. In particular, in the case of foreign language training, the playback speed can be adjusted so that accurate pronunciation can be detected, and even the telephone call contents of a long-distance external lecturer can be utilized, which maximizes the multi tasking function to the e-learning environment. To provide an educational environment for modern, advanced classrooms Its purpose.

In order to achieve the above object, the system has a key pad according to the function in the UI to allow the entire system to be controlled on the PC, and an interface jack capable of mutual communication between the system body and the PC. There is a CPU which is a processing unit, and an amplifier unit for processing sound inside and outside the system, and a stereo unit and a mono unit inside the amplifier unit, and a switch for switching stereo sound and mono sound is configured, and a woofer and There is a surround section, and there is a woofer speaker and a surround speaker terminal for their output, echo and echo volume, lectures can be conducted wirelessly anywhere in the classroom, and wireless microphone transmission and reception to receive the system sound wirelessly And a telephone input terminal for a class connected directly to a remote external lecturer by telephone. The phone input and output unit is configured, and the mobile phone and the general telephone unit are set up to output or record the contents of the telephone conversation, and the camera mode is configured to allow recording, recording, and real-time transmission for video education. Wireless voice receiver for wireless microphone transmission and sound transmitted from the system body, memory IC unit for storing and playing contents of wireless voice transmission, wireless mouse transmitter, laser pointer, earphone jack and microphone Jack, external input and output terminals of the control unit, memory output function, earphone volume, microphone volume characterized in that consisting of.

Preferred embodiments of the present invention will be described in more detail together with exemplary drawings as follows.
