Schematic Power Amplifier and Layout

How do I create a speaker Speaker is a device that uses electric current to control the varying magnetic field of electromagnetic coil to create sound. Sound occurs when the field varying magnetic field reacts with the permanent and create vibrations of sound waves.

I decided to build a compact, yet effective alarm. My demands were:- simple construction, reliable operation, very small power consumption, and, most of all, small size. I started with CMOS logic gates, but was soon forced to abandon the concept after a few unsuccessful attempts. Then I suddenly realized that a simple transistor switch might […]
