  In daily life, we often encounter the situation that the speaker has current sound, even in the absence of any music. The louder the volume, the louder the noise. Why is this? Jazz Dragon professional audio manufacturers tell you:

  We must first consider whether there are other home appliances near the speaker, such as TVs, mobile phones, etc., their signal radiation will interfere with the speaker, and these objects need to be kept away from the speaker device.

  Then we have to consider whether there is a problem with the speaker itself, check whether the interface connection at the speaker is loose, we can re-plug all the sockets, if the situation still exists, then the speaker may have electromagnetic interference, mechanical noise, heat and other reasons lead to the appearance of a current sound.

  Mechanical noise, mechanical noise is unique to active speakers. During the working process of the 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 produced by the fluorescent lamp ballast. Choosing a good quality product is still the best way to prevent this noise. In addition, we can add a rubber damping layer between the transformer and the fixing plate.

  Thermal noise. If the potentiometer is used for a long time, the contact between the metal brush and the diaphragm will be poor due to dust accumulation and wear, and noise will be generated when rotating. If the screw of the speaker is not tightened, the inverter tube is not handled properly, and mechanical noise will also be generated when playing large dynamic music. This kind of thermal noise can be dealt with by replacing low-noise components or reducing the working load of the components. In addition, reducing the operating temperature is also one of the effective methods.

  Electromagnetic interference Electromagnetic interference can be mainly divided into power transformer interference and stray electromagnetic wave interference. The interference of the power transformer is caused by the magnetic leakage of the power supply of the multimedia speaker. The effect of adding a shielding cover to the transformer is very obvious when conditions permit, which can block the magnetic leakage to the greatest extent. The shielding cover can only be made of iron materials.

  Stray electromagnetic interference is common, and speaker wires, frequency dividers, wireless devices or computer hosts can all become sources of interference. Keep the main speakers as far away as possible from the computer host as far as possible, and reduce peripheral wireless devices, which is the first point just mentioned.
