I would like to understand how the center tap terminal work in miniature speakers. I can see in the datasheet that a positive going voltage relative to this center tap can lower the output volume but it does not specify by how much?
How can I calculate that? How is the actual connection between the 3 pads?
Maybe it is just a parallel connection between the positive pad - the center tap terminal and half the speaker resistance. I just want to be sure of this.
Thanks for your help.
