i thought up an invention on the way home from work

Speakers in the helmet ??? So long security !

If you fall bad you'll end up with speakers in your head... I don't think you want that. Plus there is the risk of not hearing surrounding noises which is very dangerous.

So it hasn't been done AFAIK but I guess there is a good reason for this
