It happens even with speaker when they are turned on. One can hear a typical sound. Why is that?

Your cell phone emits a strong electromagnetic (radio) field. That can then interfere with the electronics in the monitor.
Typically a cell phone when it is not in use sends little 'chirps' out so it can talk to the cell towers around it, lets them know where it is in case somebody wants to call you, update the time, whatever else.
When you talk it links to the nearest free tower and radiates continuously. That is why you have so much more standby time compared to the talk time.
With the phone next to the computer the signal from the chirps are strong enough to induce significant voltages in the electronics of the monitor and the speakers, so you get a flicker and a click from the speakers.
It is probably a good idea to move your cell phone further away. The signal drops off quickly so you should not have to move it very far.

I'm not 100% but I think its something along the lines of this: When you recieve a phone call, text, or when your phone checks the network for new info, the electrical field created by your phone increases. It interferes momentarily with the field from your monitor and speakers, causing that clicking sound (not a very good description but best I could come up with).
Once in awhile this isn't horrible for your computer now and then, but if it happens frequently you may want to think about keeping your phone five or six feet away from it just to avoid it.

Due to the way that standard CRT monitors work, any kind of magnetic interference is going to have an effect on the display.
Most any electronic is going to emit some level of electromagnetic radiation, which will cause the flicker.

Almost all the answers you have received described this phenomenon appropriately. Moreover, It is not advisable to place your mobile phone near any electronic device from safety point of view as well, as it may sometimes erase the phone book and may even damage the software installed in your phone beyond repairs.

Screen Flickers because of the magnet present in the speaker of cell
But speakers produce sound because of radio signals
Mind u plz dont bring any thing which has magnet near you CRT monitor for long duration of time it can damage your mintor

one among some issues is occurring. the two the reveal screen is going out meaning you will would desire to purchase a sparkling one quickly, your video card would be going undesirable, or your getting surges on your line. make valuable your reveal screen and computing gadget are linked to a surge secure ability strip. it somewhat is uncommon to work out a video card inflicting flickering on a reveal, even whilst it is going undesirable, so i'd seem on the different 2 first.

Your phone ''radiates'' a signal (that's how it works). Other electronic equipment can receive these radio signals when the frequencies are close or similar to each other.

there are magnetic properties in ure cell which interfere with the magnetic devices present in it and hence it flickers
