Questions and Answers

What is the function of a transducer in the context of sound and electronics?

To convert electricity into pressure and vice versa (correct)

To interpret the sound signal received by the brain

To amplify sound waves

To generate sound waves

How do speakers work with electricity to produce sound?

The electric signal directly generates sound waves through a special membrane

The electric signal creates vibrations in the air, producing sound waves

The electric signal becomes a magnetic force using a coil, which interacts with a powerful magnet attached to a diaphragm, creating sound (correct)

The electric signal triggers a chemical reaction that produces sound

What is the role of a microphone as a transducer?

To amplify the variations of voltage/current

To interpret variations of pressure in a medium

To create vibrations in the air that produce sound waves

To transform sound waves into an electric signal (correct)
