What is the difference between a buzzer and a sounder and which would be more appropriate for a vintage car indicater audible warning (6v. negetive earth suply)

Asked by: austin33
The sound it makes, if you need to know what would sound best please visit a store for a demo. We do not provide advice on any project the best component to use you be down to yourself to choose if unsure we would advise getting in contact with an auto electrician.

Could I have a copy of the data/tech sheet please? When making lemon batteries in science club we found we get a small sound from this type of buzzer with one lemon battery, but nothing at all from other rectangular buzzers we have and we wondered why?

Asked by: Circuits
