What is the abnormal use of audio equipment? Shandong public broadcasting audio manufacturer will explain the relevant contents for you.
音响设备一开机，就&濒诲辩耻辞;嗡嗡&谤诲辩耻辞;直响，无论怎么调整音量，噪音都不能。这种情况一般都是因为长时间使用，再加上音响设备是封闭的，热量散不出去，内部温度过高，造成功放集成块过热而损坏。
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.
实际上，正品的功放集成电路都带有温度保护功能，当过热时，功放集成电路会自动停止输出，当温度降下来后，能够自动恢复工作。但是一些音响设备生产厂家为了降低生产成本，实用的不是大厂的集成电路，而使用的使一些小厂仿制的集成电路，质量低劣。
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.
刚开机时，电脑播放声音都正常，但是使用一段时间之后，就&濒诲辩耻辞;嗡嗡&谤诲辩耻辞;直响，耳朵没法忍受。这种故障同上例，不过该功放集成电路还没有损坏，但过热时才出现故障。我们可以打开机箱，通过加大攻防集成电路的散片的面积来解决。
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.
那么音响设备如何正确使用呢？
So how to use the audio equipment correctly?
要树立正确的听音观念。选择音响设备，尽量选用相对比较均衡的产物，不要过分追求高音或者低频的突出，应根据音乐选择音效，不要经常把超重低音音效开在大。
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，要有健康的耳朵保护意识。由于多媒体音响设备是近声场设备，使用时我们一般距离音响设备喇叭很近，应注意不要将音响设备音量开的过大，否则不仅会损害自己的耳朵，还会打扰到别人。
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.
此外音响设备器材的摆放，以音响设备的摆放为重要。音响设备靠墙放时应特别注意，因为墙角会形成&濒诲辩耻辞;驻波&谤诲辩耻辞;，也就是部分音波(尤其是低频)不断折射，干扰音乐，音乐听起来就不清晰。如果在墙角堆放一些过期杂志，就能产生吸收驻波的效果。关注我们

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 Yes, learn more.
