广播系统音响，从音箱的材质，木盒，纸单元盆，再加上内部的吸音棉，线缆，电容等，每个部分几乎都是易燃的，使用时要多加注意，下面
山东公共广播音响厂家为您解答更多话题。
From the material of the speaker, wooden box, paper unit basin, as well as the internal sound absorbent cotton, cables, capacitors, etc., almost every part of the audio system is flammable. Pay more attention when using it. The following Shandong public address audio manufacturer will answer more questions for you.
1.阅兵、体操、足球比赛解说等体育场扩声在使用功能上不同于厅堂扩声，它也不同于剧场扩声，它有其特殊性，除了保证洁净程度和较高的音质柔和、声压覆盖均匀，以及对功率设备的要求和保留余量外，线阵声学，由于其覆盖均匀、扩散性好、声压级大、指向性强等特点，所以我们优先选择设备。
1. Stadium sound reinforcement, such as parade, gymnastics, football match commentary, is different from hall sound reinforcement in use function, and it is also different from theater sound reinforcement. It has its particularity. In addition to ensuring the cleanliness, high sound quality, soft sound pressure, uniform coverage, and the requirements for power equipment and reserve margin, linear array acoustics, due to its uniform coverage, good diffusion, large sound pressure level, strong directivity and other characteristics, we give priority to equipment.
2.深刻认识到体育场音响系统设备的性和可靠性以及可靠的重要性，直接影响到会议的进行，所以在设计时，考虑的是系统的可靠性，这就要求在选择设备时要求设备稳定可靠，系统控制硬件和软件需要与设备具有兼容性，系统的嵌入式电路和连接电路需要采用具有较强可靠性和抗干扰能力的线路。
2. Deeply recognize the safety and reliability of stadium audio system equipment and the importance of safety and reliability, which directly affect the progress of the meeting. Therefore, the reliability of the system is the first consideration in the design, which requires that the equipment be stable and reliable when selecting equipment, and the system control hardware and software need to be compatible with the equipment, The embedded circuit and connecting circuit of the system need to adopt the circuit with strong reliability and anti-interference ability.
3.每个座位上的观众听到的响度应比较均匀，通过音质设计，应能使不同区域的观众的声压级相差不太大，室内声场均匀性应控制在3诲产左右的高度内，噪声对人的正常听觉有干扰和掩蔽作用，不同用途的室内听音环境，它允许不同的噪声级，厂狈搁应大于30诲叠。
3. The loudness heard by the audience on each seat should be relatively uniform. Through the sound quality design, the difference of sound pressure levels of the audience in different areas should not be too large. The evenness of the indoor sound field should be controlled within a height of about 3db. Noise can interfere with and mask the normal hearing of people. Different indoor listening environments for different purposes allow different noise levels, and the SNR should be greater than 30dB.
4.室内音响系统应保证整个系统的频率响应是平衡的，如果室内音响出现声聚焦、死点、驻波和声学共振等声学问题，就会破坏频率均衡，选择合适的自然混响时间，会议室的声学特性在建筑声学系统中，各种会议室音响系统是很常见的，在设计音响系统时，我们先要明确其功能要求、外形和座位布局等，对声音放大影响很大。
4. The indoor sound system should ensure that the frequency response of the entire system is balanced. If there are acoustic problems such as acoustic focusing, dead point, standing wave and acoustic resonance in the indoor sound system, the frequency balance will be broken, and appropriate natural reverberation time will be selected. The acoustic characteristics of the conference room are common in the architectural acoustic system. When designing the sound system, we should first clarify its functional requirements Appearance and seat layout have a great impact on sound amplification.
此外要注意，功率禁忌过载现象通常在给音箱配功放时，为了能让舞台音箱的性能充分发挥，功放的功率往往要比音箱功率大一些，有时大1倍左右。关注我们

In addition, it should be noted that power taboo overload phenomenon usually occurs when the speakers are equipped with professional power amplifiers. In order to give full play to the performance of the stage speakers, the power of the power amplifier is often larger than the power of the speakers, sometimes about twice as large.
