First, the conference room environment

Multimedia conference room is about 220 square meters, 16 meters × 1 4 meters.

Second, the conference room function description

Multimedia conference room to achieve the main functions: meetings, taking into account lectures, international academic exchanges and other activities, but also some of the English conference film. Learning.

Third, the conference room sound, video effects required to explain

Multimedia conference room sound effects: multimedia conference room is mainly for the transmission of language vocal signals taking into account other audio-visual information audio signals playback, in the design of the focus on the distribution of loudspeakers and sound pressure coverage of the uniformity of the system signals to deal with the interferences between each other. To achieve a variety of audio signals playback is clear and not turbid, and high school and low sound field is clear. According to the national hall sound reinforcement system design acoustic characteristics of the index standard, in the empty field steady state quasi-peak state of the maximum sound pressure level:

1, language sound reinforcement system first-class standard to be ≥ 90dB

2, music and language sound reinforcement system first-class standard to be up to ≥ 95dB

3, the unevenness of the sound field to do when the measurement of 1.0kHz and 4.0kHz ≤8dB

4, sound transmission gain in 0.125-4.0kHz average value to be ≥-8dB.

The above national standards, the project system is designed in accordance with the standards, but also to achieve the above standards. Sound effects in line with the above GYJ125 hall sound reinforcement system design acoustic characteristics of indicators in the language and music both first-class standard, to achieve a clear language, no distortion, sound pressure margin is sufficient, the sound field distribution is uniform, no acoustic feedback whistling.

Video effect description: clear text and picture.

Fourth, the multimedia conference room design

Multimedia conference room is a modern conference facilities. The system contains the means of multimedia conferencing, computer-assisted conferencing and demonstration, able to play a variety of currently popular media, should be currently popular, easy to use, the effect of the ideal conference presentation system for a variety of multimedia conferences, presentations, academic exchanges, and learning activities such as the English conference film.

Multimedia conference room to achieve two main functions: one is the meeting, international academic exchanges and conferences and other activities; one is to carry out the learning of English conference film. In the function of the meeting, the system contains a multimedia conference, computer-assisted meetings and demonstration of the means, it will be seminar system, tape recorders, DVD players, multimedia computers, video physical booths, cable TV programs, the Internet and other popular media programs through the projector and high-fidelity audio equipment, show to the audience. Make the content of the meeting vivid, visualization and concretization, the system fully embodies the role of modern multimedia conference room equipment to improve the quality of meetings. Multimedia conference room area of about 22 0 square meters. Multimedia conference room using the United States VICISI 6 12-inch speakers on both sides of the podium wall, VICISI full range coaxial loudspeaker system, in addition to having the ability to project a long distance, it is smooth power response and tone quality can also make it well adapted to near-field work. Its sensitivity of 98dB, rated input power SPL has 96dB, its horizontal radiation angle of 80 degrees, vertical radiation angle of 40 degrees, each side of the two fan-form distribution, easy to cover the whole field. Because of its point source technology, good directivity, the chance of acoustic feedback is also very small.

The main features of the conference discussion system: conference system host can be installed directly on the 19-inch standard rack; conference chairperson machine and on behalf of the machine comes with a connecting cable, using hand-holding cable connection; gooseneck conference microphone; double headset socket, the chairman of the priority, speaking LED instructions; serial 9-bit speaker unit, whistle suppression, microphone automatic shutdown; auxiliary audio signal input and output functions, easy to connect other equipment; can be connected to the audio signal input and output functions, easy to connect to other equipment; can be used in a variety of ways. function, easy to connect other equipment; access to teleconferencing; chairman unit can be used to control the priority button to control the speaking order, control the atmosphere of the meeting, while the speaking seat can be selected 1, 3, 6; with recording output (output amplitude can be adjusted) connected to the recorder function, but also external sound amplification equipment; on behalf of the chairman of the microphone volume can be adjusted to facilitate the adjustment of the sound size, to control the sound pressure on the scene; on behalf and Chairman of the unit is equipped with a speaker volume control, easy to adjust the volume of various units of the speaker; host unit has a microphone input port, and the amplitude can be adjusted, can be connected to the wired microphone and wireless microphone and so on.

Video system: large screen is the first choice, the current feasible program more projectors, more in line with the current situation. In the multimedia conference said the bigger the better the projection screen, but due to the limitations of the height of the room, the size of the projector screen can only be the height of the room in the location of the conference table. The height of the lower edge of the screen can not be in the end, otherwise the speaker will block the screen. Generally 1.2 meters high, that is, room height minus 1.2 meters is the height of the screen. In fact, the upper edge of the screen is impossible to stick to the roof, the screen box, projector hangers and so on still need some height, about a few dozen centimeters. The optimal viewing distance is roughly 4-6 times the height of the screen, equivalent to 2.4-3.6 times the diagonal length of the screen. In the design should take full account of the number of multimedia conference room and the relationship between the height of the room.

Multimedia conference room is different from the general multimedia classroom, first of all, the equipment used are high-grade, complex. To make the equipment to play the best performance, which requires specialized professionals to operate. In the actual meeting, the meeting people as long as the operation of computers and other simple equipment can be. Most of the multimedia conference tables on the podium are movable and movable. In the appropriate location of the podium on the floor to install a reversible junction box. Use it when you need to access equipment such as microphones, video presenters and laptops. Normally, multimedia equipment is placed in the equipment room on the right. In the multimedia conference room meeting can use multiple wired or wireless microphone, and the use of imported high-grade feedback suppressor, microphone in any place will not produce whistling.
