廣播系統(tǒng)音響，從音箱的材質(zhì)，木盒，紙單元盆，再加上內(nèi)部的吸音棉，線纜，電容等，每個(gè)部分幾乎都是易燃的，使用時(shí)要多加注意，下面
山東公共廣播音響廠家為您解答更多話題。
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.閱兵、體操、足球比賽解說等體育場擴(kuò)聲在使用功能上不同于廳堂擴(kuò)聲，它也不同于劇場擴(kuò)聲，它有其特殊性，除了保證潔凈程度和較高的音質(zhì)柔和、聲壓覆蓋均勻，以及對(duì)功率設(shè)備的要求和保留余量外，線陣聲學(xué)，由于其覆蓋均勻、擴(kuò)散性好、聲壓級(jí)大、指向性強(qiáng)等特點(diǎn)，所以我們優(yōu)先選擇設(shè)備。
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.深刻認(rèn)識(shí)到體育場音響系統(tǒng)設(shè)備的性和可靠性以及可靠的重要性，直接影響到會(huì)議的進(jìn)行，所以在設(shè)計(jì)時(shí)，考慮的是系統(tǒng)的可靠性，這就要求在選擇設(shè)備時(shí)要求設(shè)備穩(wěn)定可靠，系統(tǒng)控制硬件和軟件需要與設(shè)備具有兼容性，系統(tǒng)的嵌入式電路和連接電路需要采用具有較強(qiáng)可靠性和抗干擾能力的線路。
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.每個(gè)座位上的觀眾聽到的響度應(yīng)比較均勻，通過音質(zhì)設(shè)計(jì)，應(yīng)能使不同區(qū)域的觀眾的聲壓級(jí)相差不太大，室內(nèi)聲場均勻性應(yīng)控制在3db左右的高度內(nèi)，噪聲對(duì)人的正常聽覺有干擾和掩蔽作用，不同用途的室內(nèi)聽音環(huán)境，它允許不同的噪聲級(jí)，SNR應(yīng)大于30dB。
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.室內(nèi)音響系統(tǒng)應(yīng)保證整個(gè)系統(tǒng)的頻率響應(yīng)是平衡的，如果室內(nèi)音響出現(xiàn)聲聚焦、死點(diǎn)、駐波和聲學(xué)共振等聲學(xué)問題，就會(huì)破壞頻率均衡，選擇合適的自然混響時(shí)間，會(huì)議室的聲學(xué)特性在建筑聲學(xué)系統(tǒng)中，各種會(huì)議室音響系統(tǒng)是很常見的，在設(shè)計(jì)音響系統(tǒng)時(shí)，我們先要明確其功能要求、外形和座位布局等，對(duì)聲音放大影響很大。
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，功率禁忌過載現(xiàn)象通常在給音箱配功放時(shí)，為了能讓舞臺(tái)音箱的性能充分發(fā)揮，功放的功率往往要比音箱功率大一些，有時(shí)大1倍左右。關(guān)注我們

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.
