音響設(shè)備使用不正常表現(xiàn)在什么方面？
山東公共廣播音響廠家為您講解講解相關(guān)內(nèi)容吧。
What is the abnormal use of audio equipment? Shandong public broadcasting audio manufacturer will explain the relevant contents for you.
音響設(shè)備一開機(jī)，就“嗡嗡”直響，無論怎么調(diào)整音量，噪音都不能。這種情況一般都是因?yàn)殚L時(shí)間使用，再加上音響設(shè)備是封閉的，熱量散不出去，內(nèi)部溫度過高，造成功放集成塊過熱而損壞。
As soon as the audio equipment is turned on, it will "buzz". No matter how the volume is adjusted, the noise cannot be eliminated. This situation is generally due to long-term use, plus the sound equipment is closed, the heat cannot be dissipated, and the internal temperature is too high, which causes the power amplifier integrated block to overheat and damage.
實(shí)際上，正品的功放集成電路都帶有溫度保護(hù)功能，當(dāng)過熱時(shí)，功放集成電路會(huì)自動(dòng)停止輸出，當(dāng)溫度降下來后，能夠自動(dòng)恢復(fù)工作。但是一些音響設(shè)備生產(chǎn)廠家為了降低生產(chǎn)成本，實(shí)用的不是大廠的集成電路，而使用的使一些小廠仿制的集成電路，質(zhì)量低劣。
In fact, all genuine power amplifier integrated circuits have temperature protection function. When the temperature is too high, the power amplifier integrated circuit will automatically stop output, and when the temperature drops, it can automatically resume operation. However, in order to reduce the production cost, some audio equipment manufacturers do not use the integrated circuits of famous brands of large manufacturers, but use the integrated circuits imitated by some small manufacturers, with poor quality.
剛開機(jī)時(shí)，電腦播放聲音都正常，但是使用一段時(shí)間之后，就“嗡嗡”直響，耳朵沒法忍受。這種故障同上例，不過該功放集成電路還沒有損壞，但過熱時(shí)才出現(xiàn)故障。我們可以打開機(jī)箱，通過加大攻防集成電路的散片的面積來解決。
When I first started up, the sound played by the computer was normal, but after a period of use, it was "buzzing" and my ears could not bear it. This fault is the same as the above example, but the integrated circuit of the power amplifier is not damaged, but the fault occurs when it is overheated. We can open the chassis and solve the problem by increasing the area of the scattered pieces of the attack and defense integrated circuit.
那么音響設(shè)備如何正確使用呢？
So how to use the audio equipment correctly?
要樹立正確的聽音觀念。選擇音響設(shè)備，盡量選用相對(duì)比較均衡的產(chǎn)品，不要過分追求高音或者低頻的突出，應(yīng)根據(jù)音樂選擇音效，不要經(jīng)常把超重低音音效開在大。
We should establish a correct concept of listening. When selecting audio equipment, try to select relatively balanced products. Do not excessively pursue the prominence of high or low frequencies. Choose the sound effect according to the music. Do not always turn on the super bass sound effect.
其次，要有健康的耳朵保護(hù)意識(shí)。由于多媒體音響設(shè)備是近聲場設(shè)備，使用時(shí)我們一般距離音響設(shè)備喇叭很近，應(yīng)注意不要將音響設(shè)備音量開的過大，否則不僅會(huì)損害自己的耳朵，還會(huì)打擾到別人。
Secondly, we should have a healthy awareness of ear protection. Since the multimedia audio equipment is a near sound field equipment, we are usually very close to the speakers of the audio equipment. We should pay attention not to turn the volume of the audio equipment too high, otherwise it will not only damage our ears, but also disturb others.
此外音響設(shè)備器材的擺放，以音響設(shè)備的擺放為重要。音響設(shè)備靠墻放時(shí)應(yīng)特別注意，因?yàn)閴菚?huì)形成“駐波”，也就是部分音波(尤其是低頻)不斷折射，干擾音樂，音樂聽起來就不清晰。如果在墻角堆放一些過期雜志，就能產(chǎn)生吸收駐波的效果。關(guān)注我們

In addition, the placement of audio equipment is important. Special attention shall be paid when the audio equipment is placed against the wall, because the wall corner will form a "standing wave", that is, part of the sound wave (especially the low frequency) is constantly refracted to interfere with the music, and the music will not sound clear. If some outdated magazines are stacked in the corner, the effect of absorbing standing waves can be produced. Follow us http://www.zkvd.cn Yes, learn more.
