音響時(shí)常會(huì)因?yàn)楦鞣N原因而出現(xiàn)不同的聲噪聲，那么山東音響不同聲噪聲的處理方法是什么？實(shí)際上，只要進(jìn)行仔細(xì)的分析和調(diào)查，一般都能解決掉。下面來看看吧。
Sound often because of a variety of reasons and different sound noise, so shandong sound different sound noise processing method is what? In fact, with careful analysis and investigation, they can usually be solved. Take a look.
當(dāng)山東音響設(shè)備使用不當(dāng)時(shí)，有許多情況會(huì)引起噪聲，如信號(hào)干擾、接口或連接線接觸不良、音質(zhì)差等。一般來說，聲噪聲按來源大致可分為電磁干擾、機(jī)械噪聲和熱噪聲。
When shandong sound equipment is not used, there are many situations that will cause noise, such as signal interference, poor interface or connection line contact, poor sound quality. Generally speaking, acoustic noise can be roughly divided into electromagnetic interference, mechanical noise and thermal noise according to the source.
電磁干擾聲噪聲：
電磁干擾可分為電力變壓器干擾和雜散電磁波干擾。這種噪音通常表現(xiàn)為輕微的嗡嗡聲。一般來說，電源變壓器的干擾是由多媒體揚(yáng)聲器電源的漏磁引起的。在條件允許的情況下，安裝變壓器屏蔽罩的效果非常明顯，可以較大限度地阻斷漏磁。屏蔽蓋只能由鐵材料制成。我們應(yīng)該盡量選擇大企業(yè)和堅(jiān)固材料的產(chǎn)品。此外，使用外部變壓器也是一個(gè)很好的解決方案。
Electromagnetic interference sound noise:
Electromagnetic interference can be divided into power transformer interference and stray electromagnetic interference. The noise usually appears as a slight hum. In general, interference from power transformers is caused by magnetic leakage from the multimedia speaker power supply. When conditions permit, the effect of installing transformer shield is very obvious, which can block magnetic flux leakage to a large extent. Shield cover shall only be made of iron material. We should try to choose products with big brands and strong materials. In addition, the use of external transformers is also a good solution.
雜散電磁波聲噪聲：
雜散電磁波干擾很常見。揚(yáng)聲器電線、分頻器、無線設(shè)備或計(jì)算機(jī)主機(jī)將成為干擾源。在允許的條件下，使主揚(yáng)聲器盡可能遠(yuǎn)離計(jì)算機(jī)主機(jī)，并減少周圍的無線設(shè)備。
Stray electromagnetic wave acoustic noise:
Stray electromagnetic interference is common. Loudspeaker wires, dividers, wireless devices, or computer hosts will be the source of interference. Keep the main speaker as far away from the main computer as possible and minimize surrounding wireless devices.
機(jī)械聲噪聲：
機(jī)械噪音不是有源揚(yáng)聲器特有的。電力變壓器在運(yùn)行過程中，由交變磁場(chǎng)引起的鐵芯振動(dòng)會(huì)產(chǎn)生機(jī)械噪聲，與熒光燈鎮(zhèn)流器發(fā)出的嗡嗡聲非常相似。選擇高質(zhì)量的產(chǎn)品仍然是防止這種噪音的好辦法。此外，我們可以在變壓器和固定板之間安裝橡膠阻尼層。
山東音響提醒注意，如果長(zhǎng)期使用電位計(jì)，由于灰塵積聚和磨損，金屬刷和膜片之間會(huì)接觸不良，旋轉(zhuǎn)時(shí)會(huì)產(chǎn)生噪音。如果揚(yáng)聲器的螺絲沒有擰緊，變頻器沒有處理到位，播放大型動(dòng)態(tài)音樂時(shí)也會(huì)產(chǎn)生機(jī)械噪音。這種噪音的一般特征是用音量或高低音量旋鈕調(diào)節(jié)音量時(shí)發(fā)出異常的咔噠聲。
Mechanical noise:
Mechanical noise is not unique to active speakers. During the operation of a power transformer, the vibration of the iron core caused by the alternating magnetic field will produce mechanical noise, which is very similar to the buzzing sound emitted by a fluorescent lamp ballast. Choosing high-quality products is still a good way to prevent this noise. In addition, we can install a rubber damping layer between the transformer and the fixed plate.
Shandong sound reminds that if the potentiometer is used for a long time, due to dust accumulation and wear, there will be poor contact between the metal brush and the diaphragm, and noise will be generated when rotating. If the screws of the speaker are not tightened and the frequency converter is not processed in place, mechanical noise will also be generated when playing large dynamic music. A common feature of this noise is an unusual clicking sound when the volume is adjusted with a volume or high or low volume knob.
