Why does the mobile phone ring when it is placed next to the stereo?

When your mobile phone is in use, it is close to the stereo, landline, TV, etc. And it will be interfered by the strong signal of the mobile phone.

Of course, if you are useless, put it near the stereo, the speaker of the stereo will squeak from time to time, because the mobile phone will automatically get in touch with the radio station at any time, and the mobile phone and the radio station will exchange signals with each other.

If the phone rings, your computer screen will also vibrate.

To put it bluntly, it is the interference caused by strong radio waves emitted by mobile phones.

A mobile phone will generate a large number of electromagnetic waves when surfing the Internet, talking and texting. The sound horn consists of a cone, a coil and a magnet. The shell of sound is not shielded. In the case of electromagnetic signal interference, the voice coil will be disturbed, and then pulse sound signals will be generated. This pulse signal is amplified by the audio circuit and sent to the speaker. At this time, you will hear the harsh sound from the audio.

Solution:

1, choose good audio equipment and signal line, because good quality audio circuit has reasonable design and good anti-interference effect.

2. Keep the mobile phone away from the stereo, which will cause little or no interference to the stereo.
