Electronics/Alarm Bell with different ringtones.
Is it possible to customise alarm Bell product with different ringtones for the wired Alarm Bell product?.
This could be possible by designing a remote control which will have push buttons Triggered for setting different ringtones in the wired Alarm Bell product?.
Alarm bells can be a very wide range of applications. The sleep alarm on a smartphone is for personal use as the audio output is a low level. But, there are apps which can be downloaded from the Apple and/or Android app stores that have such functionality available. Then the output of the smartphone could be connected to external amp/speaker, for example.
I the alarm bell is a physical ringer using a clapper that is electrically driven to strike the bell according to the power line voltage I don't think you can add ringtones to these electric/mechanical products.
For any other electronic alarm system an electronics engineer could design a module to add the ringtone circuits and switching bank to give exactly what you are asking about.
