会议音响它似乎很简单,容易连接扬声器,功率放大器,会议麦克风,混合动力游戏机和其他设备,但事实并非如此。
Conference audio seems very simple, easy to connect speakers, power amplifiers, conference microphones, hybrid game consoles and other equipment, but this is not the case.
会议室音响系统设计中需要考虑的问题很多,如抗干扰、减少声反馈、避免嚎叫、人声清晰透明、会议环境舒适自然等。选择合适的会议室音响系统将使会议更加有效,选择合适的专用的音响制造商将解决所有的技术问题。
There are many problems to be considered in the design of conference room sound system, such as anti-interference, reducing sound feedback, avoiding howling, clear and transparent voice, comfortable and natural conference environment, etc. Choosing the right conference room sound system will make the meeting more effective, and choosing the right dedicated sound manufacturer will solve all technical problems.
一般箱体较薄或塑料外壳的音箱在200贬锄以下的低频段大音量输出时,会发生谐振现象。出现箱体谐振会严重影响输出的音质,所以用户在挑选专用的音箱时应尽量选择木制外壳的专用的音箱。
Generally, when the speaker with a thin box or a plastic shell outputs large volume at a low frequency band below 200Hz, resonance will occur. The box resonance will seriously affect the output sound quality, so users should try to choose a special speaker with a wooden shell when selecting a special speaker.
由于显示器对周围磁场十分敏感,如果专用的音箱箱体的磁场较大会使荧屏上的图像受到影响,甚导致显示器的寿命下降,因此在挑选时要格外注意。
Since the display is very sensitive to the surrounding magnetic field, if the magnetic field of the special speaker box is relatively large, the image on the screen will be affected, or even the life of the display will be reduced. Therefore, special attention should be paid to the selection.
因为专用的扬声器的气密性越好,输出的声音质量就越好。气密性检测方法非常简单。使用者可以将手放在扬声器的反转孔外。如果他们觉得有明显的空气涌出或吸入,这意味着扬声器的气密性良好。
Because the better the air tightness of the special loudspeaker is, the better the sound quality will be. The air tightness test method is very simple. The user can place his hand outside the reversing hole of the loudspeaker. If they feel that there is obvious air coming out or in, it means that the air tightness of the speaker is good.
