The cup pushes air back and forth, creating a sound that travels to your ear. The bare wire itself does not move much air, so it does not make much sound. However, if the coil is attached to a large, low-mass material, it will vibrate that material which, in turn, will vibrate the air, making a louder sound.

What is a passive amplifier?
A passive amplifier amplifies sound (increases the amplitude of acoustic power, sound intensity and sound pressure level) by passive means. In order words, it does so without the use of external electrical power or additional energy of any sort. There are different ways in which sound can be “amplified”.
How does a passive speaker amplify sound?
Passive speakers work using an amplified signal. If the speaker has more than one driver (such as a mid/bass unit and a tweeter), the signal gets split into those low and high frequencies in a circuit called a crossover.
How do wooden passive amplifiers work?
It’s called a passive speaker, and it works the same way a megaphone does. A passive speaker takes the sound from the bottom and channels it in a single direction – forward – which immediately makes it easier to hear in the same way a megaphone directs sound at a crowd.

Why do speakers require magnets?
Answer: Every amplifier (speaker) has an electrical current. When the current is changing, it produces a magnetic field. To make the cone (or panel) of the speaker move, magnets are used to create an opposing magnetic field which creates vibrations. These vibrations are the sound we hear.
How do homemade speakers work?
A speaker works by attaching an electromagnet to some sort of flexible cone and putting it close to a permanent magnet. The sound transmitted through the wire as an electrical signal changes the magnetic field of the electromagnet, which attracts and repels the nearby permanent magnet.
What materials amplify sound the best?
The best materials for carrying sound waves include some metals such as aluminum, and hard substances like diamond.
Does putting a speaker in a box make it louder?
Thanks. Yes, it will sound much better with a properly designed box, and with a properly designed crossover that divides the frequency spectrum to each respective driver.
How do you amplify sound in physics?
Sounds can be made louder or amplified in a number of ways. By providing more energy in making the sound its loudness can be increased. This would be achieved by beating a drum with greater vigour, blowing harder on the recorder or using more bodily energy in shouting louder.
