在音响系统的设计中，由于报告厅的多样化需求，音响技术的设计需要实现多功能应用、方便灵活的可扩展性等。让我们来看看报告厅的声音响应是如何设计成多组件的。
In the design of professional audio system, due to the diversified needs of the lecture hall, the design of professional audio technology needs to achieve multi-functional application, convenient and flexible scalability, etc. Let's take a look at how the professional voice response of the lecture hall is designed into multiple components.
扩声系统和拾音系统设计
Design of sound reinforcement system and pickup system
扩声系统要求扬声器均匀地覆盖观众区的直达声，以免声音干扰过度重复，影响清晰度。方来的感觉，要求扩声清晰响亮，有较高的传声增益。
The sound reinforcement system requires the speakers to cover the direct sound in the audience area evenly, so as to avoid excessive repetition of sound interference and affect the definition. Fang Lai's feeling requires clear and loud sound reinforcement with high sound transmission gain.
播放音乐节目时，要求声音丰富、自然、清晰、明亮。保证整个扩声系统的高可靠性、简单明了的控制、设备的可扩展性。报告厅扩声系统适用于各种文艺演出、歌舞表演、校务会议、学术报告灯光活动的需要。
When playing music programs, the sound shall be rich, natural, clear and bright. Ensure the high reliability, simple and clear control and equipment scalability of the whole sound reinforcement system. The sound reinforcement system of the lecture hall is applicable to the needs of various artistic performances, song and dance performances, school meetings, academic reports and lighting activities.
报告厅主扩声系统
Main sound reinforcement system of lecture hall
在主扩声扬声器的布置和选择上，可以采用线阵列扬声器作为主扩声系统，阵列全频扬声器分别悬挂安装在舞台前方的左上方和右上方。舞台采用特殊吊架，实现全场高声覆盖。速率保证了声音的丰满度和丰富度。阵列低频扬声器放置在舞台两侧的地面上或隐藏在墙下或舞台下方，以增强音频的动态和丰满度。
In terms of the layout and selection of the main sound reinforcement speakers, the line array speakers can be used as the main sound reinforcement system, and the array full frequency speakers are respectively suspended and installed at the upper left and right in front of the stage. Special hangers are used on the stage to achieve high sound coverage of the whole audience. Speed ensures the fullness and richness of sound. Array low-frequency speakers are placed on the ground on both sides of the stage or hidden under the wall or under the stage to enhance the dynamic and fullness of audio.
全填充扬声器和唇填充扬声器
Full fill speakers and lip fill speakers
根据报告厅的大小，在观众区的左右墙上放置补声喇叭，负责填补主扩声系统声音所覆盖的盲区，让前场的观众可以体验到更完整的音效。扬声器系统的合理布局和选型，满足观众区对响度、声场均匀性和音质的要求。唇填式音箱提供了舞台口周围声源的补充功能。
According to the size of the lecture hall, fill in the blind area covered by the sound of the main sound reinforcement system by placing fill in speakers on the left and right walls of the audience area, so that the front audience can experience a more complete sound effect. The reasonable layout and type selection of loudspeaker system shall meet the requirements of audience area for loudness, sound field uniformity and sound quality. The lip filled speaker provides a supplementary function for the sound source around the stage opening.
另外，通过分析报告厅的布置环境，合理安排和连接
报告厅音响设备，并安装好上述音响设备，使声源和音响系统的末端&尘诲补蝉丑;&尘诲补蝉丑;音箱位于相同的声场面积，让观众感受到声源的真实存在，满足高保真播放的扩声要求。声音以自然声为主，要求扩散性好、声场分布均匀、响度合适、自然度好。
In addition, by analyzing the layout environment of the lecture hall, reasonably arrange and connect the sound equipment of the lecture hall, and install the above sound equipment, so that the sound source and the end of the sound system - the speaker are located in the same sound field area, so that the audience can feel the real existence of the sound source and meet the sound reinforcement requirements of high fidelity broadcasting. The sound is mainly natural sound, which requires good diffusion, uniform sound field distribution, appropriate loudness and good naturalness.
