Hi all,
I am an industrial design student and currently i am trying to design an electromechanical doorbell. After looking at the existing electromechanical doorbell, the chimes are all very big. I am just wondering what is the minimum size of the tone bar for it to be able to produce an audible sound?
Thanx for your help
