How Microphones and Speakers Work: Electromagnetic Induction and Motor Effects

The video tutorial explains the working principles of microphones and speakers. It begins with an overview of how these devices function, focusing on the conversion of sound waves to electrical signals in microphones and the reverse process in speakers. The tutorial details the components involved, such as coils, diaphragms, and magnets, and describes the role of alternating currents in producing sound.

What role does the amplifier circuit play in the functioning of a microphone?

How does the interaction between the coil and the magnetic field in a speaker produce sound waves?
