Why does the circuit board hum when PS4 controller is loaded?

I have a controller here.

As soon as I want to load, or it loads, hum? Capacitors? On the controller board. Or a certain area hums on the controller.

Why is that?

Can you fix that?

This is normal, is just the vibration of magnetic fields caused by electricity (think was alternating current.)

With a charger, it should help if you turn the plug. To be honest, I've never tested whether it really works.

It also hums when I want to charge the controller via the PS. In other words, as soon as there's current flowing, parts of the circuit board of the controller hum. And it's not normal because I have other controllers that I hear absolutely nothing when it loads: / :)

Gu

"when they are loaded," I mean.

Jo

Both when it is being charged or when this controller is just on, current flows in both cases.

And it's normal, some more and less. Depends on the age of the device and also on the type of tree.

If the humming is very loud, it is no longer normal. A slight "hum" is often present because electricity is flowing.

Gu

Aha. Isn a fake controller XD so I ask. Can you do anything there?

Jo

No not true. It is simply due to the quality of the components that are installed, which are difficult to change yourself.

Perhaps some silicone covers for the controller would reduce the noise, if there are suitable ones for your controller.

If the controller hums, then the USB power supply is too weak or "too cheap".

There's a voltage regulator in the controller because the built-in battery has a lower voltage than the 5V from the USB socket.

If the USB power supply is overloaded or cheap, the output voltage fluctuates in line with the line voltage. The output voltage then collapses in the zero crossings of the mains sine. This creates a voltage fluctuation of 100 Hz.

The regulator in the controller has to compensate for this. If the voltage collapses, it regulates the current up in order to be able to deliver a constant output. These current fluctuations can then cause coils in particular to vibrate mechanically with the frequency of the fluctuation, i.e. 100Hz.
