經(jīng)過(guò)對(duì)報(bào)告廳的布局和環(huán)境的分析，音響公司要做到的就是對(duì)音響設(shè)備的合理布局與連接，使觀眾能真實(shí)感受到聲源的存在，今天小編和大家分享一下報(bào)告廳音響的配置和安裝的方式。
After analyzing the layout and environment of the lecture hall, what the audio company wants to do is to reasonably arrange and connect the audio equipment so that the audience can truly feel the existence of the sound source. Today, the editor will share with you the configuration and installation of the audio in the lecture hall.
報(bào)告廳音響以自然聲為主，要求擴(kuò)散性良好，聲場(chǎng)分布均勻，響度合適，自然度好等要求。
The sound of the lecture hall is mainly natural sound, which requires good diffusion, uniform sound field distribution, appropriate loudness and good naturalness.
1、保證均勻合理的聲壓級(jí)。
1. Ensure uniform and reasonable sound pressure level.
2、保證清晰度。
2. Ensure clarity.
3、保證系統(tǒng)能穩(wěn)定工作。
3. Ensure that the system can work stably.
4、應(yīng)具有良好的傳輸頻率特性和較低的失真度。
4. It shall have good transmission frequency characteristics and low distortion.
報(bào)告廳音響安裝組合方式
Audio installation and combination mode of lecture hall
1、組音箱。
1. Group speakers.
2、組壁掛式音箱。
2. Group wall mounted speakers.
3、吸頂音箱。
3. Ceiling Speaker.
注意：
be careful:
安裝要求需要分別均勻安裝在報(bào)告廳會(huì)場(chǎng)前、中、后位置(其中前場(chǎng)1組音箱為主席臺(tái)監(jiān)聽)，組吸頂式音箱布置于會(huì)場(chǎng)頂部中間位置進(jìn)行近距離擴(kuò)聲。達(dá)到擴(kuò)聲面廣、聲清晰明亮，不易產(chǎn)生自激。
Installation requirements: it shall be installed in the front, middle and rear positions of the conference hall (one group of loudspeakers in front of the conference hall shall be monitored by the rostrum), and the group of ceiling mounted loudspeakers shall be arranged in the middle of the top of the conference hall for close range sound amplification. The sound amplification surface is wide, the sound is clear and bright, and it is not easy to generate self excitation.
聽眾席有合適的響度。良好的聲音自然度，即聲像一致，聲音信號(hào)真實(shí)重放。使與會(huì)人員能感受到聲源的真實(shí)存在，達(dá)到高保真重放的擴(kuò)聲要求。且達(dá)到多媒體報(bào)告廳音響以自然聲為主，要求擴(kuò)散性良好，聲場(chǎng)分布均勻，響度合適，自然度好等要求。
The auditorium has a proper loudness. Good sound naturalness, i.e. the sound image is consistent and the sound signal is truly reproduced. So that the participants can feel the real existence of the sound source and meet the sound amplification requirements of high fidelity playback. It also meets the requirements that the audio of the multimedia report hall is dominated by natural sound, with good diffusion, uniform sound field distribution, appropriate loudness and good naturalness.
報(bào)告廳音響與放大器的連線應(yīng)該盡量做到短而粗。目前國(guó)內(nèi)市場(chǎng)上有專門用于連接音箱的無(wú)氧鋼線，對(duì)改善音質(zhì)確有一定的幫助，可根據(jù)投資情況選用。
The connection between the speaker and the amplifier in the lecture hall should be short and thick as possible. At present, there are oxygen free steel wires specially used for connecting the speakers in the domestic market, which are really helpful for improving the sound quality, and can be selected according to the investment situation.
報(bào)告廳音響所能承受的功率有限，不能使其在滿負(fù)荷下工作，一般大于小功率即可。如果長(zhǎng)時(shí)間讓音箱工作在極限功率，其壽命會(huì)減少，嚴(yán)重時(shí)還會(huì)損壞音箱。
The power that the audio system in the lecture hall can bear is limited, so it can not work under full load. Generally, it can be greater than the small recommended power. If the speaker is allowed to work at the limit power for a long time, its life will be reduced, and the speaker will be damaged in serious cases.
此外清潔報(bào)告廳音響要用柔軟的濕布，不需任何清潔劑音箱網(wǎng)罩容易落灰塵，可用細(xì)毛刷進(jìn)行清潔。更多相關(guān)事項(xiàng)就來(lái)我們網(wǎng)站
