What do you call the loud noise maker that is usually used in a ball game?

Question

I usually see it in a can. It looks like a can with something that looks like a sprayer with a megaphone trumpet on top.

Optional Question:
Do you know where I can buy one here in the Philippines?

Thanks in advance.
