Microphones, Loudspeakers & Headphones

The video tutorial explains the basic design and function of microphones and loudspeakers, both of which are transducers that convert energy from one form to another. It details the components and working principles of a loudspeaker, including the use of an annular magnet and the motor effect to produce sound waves. Similarly, it describes the microphone's design, which uses electromagnetic induction to convert sound waves into electrical signals. The tutorial highlights the similarities in design between the two devices and notes that a loudspeaker can function as a microphone, albeit not very effectively.
