Why do speakers "buzz" when you put a mobile phone near them?

Question

For any Americalanders, the word "mobile" in the question can be interchangeable with the word "cell"... even though the latter implies that it is being held captive.

Answer 1

Florists have freakishly large hands?

Nothing wrong with it, just noticed it the other day.

Answer 2

never done it don't know

Answer 3

generally the speaker wires ( an antenna)  pick up enough of the transmitted signal for you to notice it's effect .

Answer 4

A cellular telephone is just one kind of mobile telephone.  Cellular does not imply captive.  It refers to the system design where a single antenna covers a small geographic area (a cell).   It includes a transmitter, which occasionally transmits digital signals to report its location and to check whether there is any new incoming call, message, or voicemail.  Speaker wires would capture some of that radio signal, but that wouldn't be enough to produce sound in the speakers.  But they carry that signal back to the receiver or amplifier, where it's detected by the receiver or amplifier circuitry.

Answer 5

The signals that go to ur speaker are electromagnetic and they are of a particular frequency........your mobile phones also receive the same signals but of a different frequency.......when they meet , they disrupt and the final electromagnetic waves reaching the speaker is of a higher amplitude.......thus , it causes more vibration and results in a distorted sound
