Reasons and solutions for abnormal sound of patch inductor

The analysis has the following points:


Circuit current

Look at the current waveform of the inductor. If the waveform is normal, it is the quality of the inductor. If the waveform is not normal, you must debug the circuit.

 

2. Circuit winding process

Check whether the current of the circuit and the wire diameter of the inductor are consistent with the over-current. Then look at the inductor winding and the process, such as whether the winding is too loose or the product is fixed well.

 

3. Magnetic stretching

The physical source of the inductive noise is in the magnetic expansion and contraction, and then amplified by the transmission medium, and it is also caused by the audio. The occurrence of noise is basically unsolvable. There is no way to completely avoid it. However, you can find ways to reduce it and reduce it. , And to avoid audio problems to solve customer problems, generally cut off the communication path is the simplest and most effective method, such as impregnating every water, to strengthen the dispensing, so that the line is more solid, change magnetic expansion or magnetic leakage less iron core And so on, are the simplest and most effective ways
