Stray electromagnetic interference is more common. Speaker wires, crossovers, wireless devices or computer hosts will all become sources of interference. Keep the main speaker as far away as possible from the computer host and reduce peripheral wireless devices.
Mechanical noise is not unique to active speakers. During the operation 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 of fluorescent lamp ballasts. Choosing good quality products is still the best way to prevent this kind of noise. In addition, we can add a rubber damping layer between the transformer and the fixed plate.
One more point should be noted. If the potentiometer is used for a long time, the metal brush and the diaphragm will have poor contact due to dust accumulation and wear, and noise will be generated when rotating. If the screws of the speaker are not tightened, the inverter will not be handled properly, and mechanical noise will also be generated when playing big dynamic music. This kind of noise is generally manifested as a crater noise when the volume or high and bass knobs are used to adjust the volume.
This kind of thermal noise can be dealt with by replacing low-noise components or reducing the working load of components. In addition, reducing the working temperature is also one of the effective methods.
In addition, some computer speakers may cause noise when the volume is adjusted too high. This situation is because the output power of the power amplifier may be small, and the large dynamic peak signal at the moment of music cannot be avoided or because the speaker is overloaded and distorted. This kind of noise is characterized by hoarse and weak sound. Although loud, the sound quality is extremely poor, the tone is dry, the treble is rough, and the bass is weak. At the same time, if there is an indicator light, you can see that with the beat of the music, the indicator light will flicker and dim. This is because the circuit's power supply voltage is severely pulled down under overload conditions.
