Physics/Alarm Bell with different ringtones.


Dear Prof Steve

Is it possible to customise alarm Bell product with different ringtones?.

This could be possible by designing a remote control which will have push buttons Triggered for setting different ringtones?.


Hello Prashant,

Many alarms use the car's horn. Of course that design would not allow sophisticated ringtones. More sophisticated alarms run a series of tones that sound like the sirens of various emergency vehicles. I don't know how those tones are produced, but they likely could play music if that is what you want. Alarm systems already commonly interface with a remote control, so they could be upgraded to allow selecting ringtones.

So yes - that could be done. In fact I decided to do a search
[car Alarm with different ringtones].
It has been done.

I'm sorry this was late. As I get older, it seems time goes faster.

I would be delighted to help with questions up through the first year of college Physics. Particularly Electricity, Electronics and Newtonian Mechanics (motion, acceleration etc.). I decline questions on relativity and Atomic Physics. I also could discuss the Space Shuttle and space flight in general.


I have a BS in Physics and an MS in Electrical Engineering. I am retired now. My professional career was in Electrical Engineering with considerable time spent working with accelerometers, gyroscopes and flight dynamics (Physics related topics) while working on the Space Shuttle. I gave formal classroom lessons to technical co-workers periodically over a several year period.
