Piezo buffer

piezo buffer for impedance match

story

Circuit selection, tries and modifications

We try every circuit on the protoboard before wiring

We use small cases to include the buffer, even small loudspeakers have enough sound definition

Impedance match for piezo electric microphones

We download and study different types of circutis

We test all the circuits

We minimize the circuit size on the board

We use small aluminium cases for the em isolation
