音響設備使用不正常表現在什么方面？
山東公共廣播音響廠(chǎng)家為您講解講解相關(guān)內容吧。
What is the abnormal use of audio equipment? Shandong public broadcasting audio manufacturer will explain the relevant contents for you.
音響設備一開(kāi)機，就“嗡嗡”直響，無(wú)論怎么調整音量，噪音都不能。這種情況一般都是因為長(cháng)時(shí)間使用，再加上音響設備是封閉的，熱量散不出去，內部溫度過(guò)高，造成功放集成塊過(guò)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功能，當過(guò)熱時(shí)，功放集成電路會(huì )自動(dòng)停止輸出，當溫度降下來(lái)后，能夠自動(dòng)恢復工作。但是一些音響設備生產(chǎn)廠(chǎng)家為了降低生產(chǎn)成本，實(shí)用的不是大廠(chǎng)的集成電路，而使用的使一些小廠(chǎng)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(kāi)機時(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(méi)法忍受。這種故障同上例，不過(guò)該功放集成電路還沒(méi)有損壞，但過(guò)熱時(shí)才出現故障。我們可以打開(kāi)機箱，通過(guò)加大攻防集成電路的散片的面積來(lái)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.
那么音響設備如何正確使用呢？
So how to use the audio equipment correctly?
要樹(shù)立正確的聽(tīng)音觀(guān)念。選擇音響設備，盡量選用相對比較均衡的產(chǎn)品，不要過(guò)分追求高音或者低頻的突出，應根據音樂(lè )選擇音效，不要經(jīng)常把超重低音音效開(kāi)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意識。由于多媒體音響設備是近聲場(chǎng)設備，使用時(shí)我們一般距離音響設備喇叭很近，應注意不要將音響設備音量開(kāi)的過(guò)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.
此外音響設備器材的擺放，以音響設備的擺放為重要。音響設備靠墻放時(shí)應特別注意，因為墻角會(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(lè )，音樂(lè )聽(tīng)起來(lái)就不清晰。如果在墻角堆放一些過(guò)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://m.djfrj.net.cn Yes, learn more.
