conference room design scheme (I)

With the continuous promotion of modern multimedia conference in various enterprises, single multimedia technology no longer meets the needs of modernization, and new multimedia conference rooms integrating multi-functional systems have been more widely used in various industries.

With the development of the times, people's requirements for the conference system are constantly improving. However, in the process of the conference, some equipment needs manual operation, and the frequent switching of various equipment and cumbersome operation of equipment make the staff in a hurry, which leads to low conference efficiency. Therefore, the modern multimedia conference room pursues the humanization and intelligence of multimedia system. With the rapid development of multimedia technology, the need to build a multimedia room with integrated audio and video and conference functions has become a reality. In addition to considering the traditional meeting requirements, it should also have the characteristics of elegant style and beautiful sound quality, clear image demonstration, convenient and fast control, highly centralized management and so on. The conference system of multimedia room consists of large screen display, multimedia audio and video signal source, audio, switching and central integrated control. Select a large screen projector to restore and amplify the VGA and video signals of DVD, computer and multimedia exhibition platform into images, and restore and amplify the audio through the sound reinforcement system. In order to carry out more efficient and real-time control, a set of central integrated control equipment is needed to control all indoor audio-visual equipment, signal switching, lighting, screen lifting, volume adjustment and other functions, which greatly improves work efficiency and simplifies complicated operations, and can be used by all people without professional knowledge.

second, the function description of the conference room

the multimedia conference room mainly realizes functions: meeting, taking into account activities such as lectures and international academic exchanges, and also learning some English conference films.

3. Description of requirements for sound and video effects of conference rooms

Description of sound effects of multimedia conference rooms: The multimedia conference rooms mainly transmit speech and human voice signals and play audio signals of other audio-visual materials. In the design, the distribution of speakers, the uniformity of sound pressure coverage and the treatment of mutual interference between system signals are mainly considered. Make all kinds of audio signals play clearly without turbidity, and the low sound field in high school is clear. According to the acoustic characteristic index standard of national hall sound reinforcement system design, the maximum sound pressure level in the state of quasi-peak in the open field is:

1, the first-class standard of language sound reinforcement system should be ≥9dB

2, the first-class standard of music and language sound reinforcement system should be ≥95dB

3, the sound field unevenness should be measured at 1.kHz and 4.kHz ≤8dB

4.

the above are national standards, and the system of this project is designed according to the standards, and it also meets the above standards. The acoustic effect conforms to the first-class standard of both language and music in the acoustic characteristic index of GYJ125 hall sound reinforcement system design, and achieves clear language, no distortion, sufficient sound pressure margin, uniform sound field distribution and silent feedback howling.

description of video effect: clear text and picture.

IV. Design scheme of multimedia conference room

Multimedia conference room is a modern conference facility. The system includes multimedia conference, computer-aided conference and demonstration, and can play all kinds of popular media at present. It should be a popular, easy-to-use and ideal conference demonstration system at present, which is suitable for all kinds of multimedia conferences, special lectures, academic exchanges and learning English conference films.

the multimedia conference room mainly realizes two functions: one is meetings, international academic exchanges and conferences; One is to learn English conference films. In terms of conference function, the system includes multimedia conference, computer-aided conference and demonstration. It will present various popular media programs such as conference system, tape recorder, DVD player, multimedia computer, video booth, cable TV program and Internet to the audience through projectors and hi-fi audio equipment. It makes the content of the meeting vivid, vivid and concrete, and the system fully embodies the role of modern multimedia conference room equipment in improving the quality of the meeting. The area of multimedia conference room is about 22 square meters. In the multimedia conference room, 6 12-inch speakers from American VICCI are used to separate the two sides of the podium. The VICCI full-range coaxial speaker system not only has the ability of long-range projection, but also its smooth power response and timbre quality can make it adapt to near-field work well. Its sensitivity reaches 98dB, the rated input power sound pressure level is 96dB, its horizontal radiation angle is 8 degrees, and its vertical radiation angle is 4 degrees, and it is distributed in the form of two fans on each side, which easily covers the whole field. Because of its point sound source technology, good directivity, the probability of acoustic feedback is also very small.

main functions of the conference discussion system: the host of the conference system can be directly installed on a 19-inch standard rack; The conference chair machine and the representative machine are immediately attached with connecting cables, which are connected hand in hand; Gooseneck conference microphone; Double earphone socket, chairman's priority, LED indication of speech; Tandem 9-bit speech unit, howling suppression, microphone automatic shutdown; There are auxiliary audio signal input and output functions, which are convenient for connecting other equipment; Access to teleconference; The chairman unit can use the priority button to control the order of speaking and the atmosphere of the meeting, and at the same time, the number of speaking seats can be selected from 1, 3 and 6; It has the function of recording output (the output amplitude can be adjusted) connected with a tape recorder, and can also be connected with external audio amplification equipment; On behalf of the chairman, the microphone volume can be adjusted, which can easily adjust the sound volume and control the on-site sound pressure; Speaker volume control is arranged on the delegate and chairman units, which is convenient to adjust the speaker volume of various units; The host unit is provided with a microphone input port with adjustable amplitude, and can be connected with wired microphones and wireless microphones.

video system: the large screen is the first choice. At present, the feasible scheme mostly adopts the projector, which is more in line with the actual situation. In the multimedia conference, it is said that the bigger the projection screen, the better. However, due to the limitation of room height, the screen size of the projector can only be determined by the height of the conference table in the room. The height of the lower edge of the screen can't reach the bottom, otherwise the speaker will block the screen. Generally, it is 1.2 meters high, which means that the height of the room MINUS 1.2 meters is the height of the screen. In fact, it is impossible to attach the upper edge of the screen to the roof, and the screen box and the hanger of the projector still need some height, about several tens of centimeters. The best viewing distance is about 4-6 times the height of the screen, which is equivalent to 2.4-3.6 times the diagonal length of the screen. The relationship between the number of people in the multimedia conference room and the height of the room should be fully considered in the design.

Multimedia conference rooms are different from ordinary multimedia classrooms. First of all, the equipment used is high-grade and complicated. To get the best performance of the equipment, it needs special professionals to operate it. In an actual meeting, the participants only need to operate simple equipment such as computers. Most of the multimedia conference tables on the rostrum are movable and movable. Install a clamshell junction box on the floor at the appropriate position of the rostrum. Use when you need to connect microphones, video display tables and laptops. Usually, multimedia equipment is placed in the equipment room on the right. Multiple wired or wireless microphones can be used in multimedia conference rooms, and imported high-grade feedback suppressors can be used, so that microphones will not whistle anywhere.
