A traditional speaker produces sound waves when a current is passed through a coil near a magnet. The current varies with the amplitude and frequency of the desired sound. As current passes though the coil, it is attracted to and repelled from the magnet. A cone of paper, plastic, bamboo, or other durable material is attached to the coil, so as the coil makes its movements the paper moves with it. The paper pushes and pulls against the ambient air creating compression sound waves.
What else can I help you with?
How is sound energy carried away from a drum?
Sound energy is carried away from a drum through the vibration of the drumhead, which creates compressional waves in the air. These waves travel as sound waves to reach our ears, where they are converted into nerve impulses that our brain interprets as sound.
How does the physics of a speaker enable it to produce sound waves?
A speaker produces sound waves through the physics of electromagnetism. When an electrical signal is sent to the speaker, it creates a magnetic field that interacts with a diaphragm or cone, causing it to vibrate and push air molecules, creating sound waves that we hear.
Can compressional waves travel through a vacuum?
No, compressional waves require a medium to travel through, so they cannot travel through a vacuum where there is no matter. Sound waves, which are compressional waves, cannot propagate through a vacuum.
What type of energy is given out by a loud speaker?
Sound energy is given out by a loud speaker. This energy is produced by the vibration of the speaker cone, which creates variations in air pressure that we perceive as sound.
Does sound travel in a compressional or surface wave?
Sound travels in compressional waves, also known as longitudinal waves, where the particles of the medium vibrate parallel to the direction of the wave's motion.
How waves are created and propagate when a tuning fork is struck?
Because of the tuning fork's vibrations. It creates compressional sound waves.
Are sound waves transverse waves or compressional waves Why?
Compressional, gasses can be compressed but cannot be wiggled side to side.
What kind of waves does sound have transverse waves or compression waves?
Sound is a compressional wave.
Why are sound waves compressional waves?
Sound waves are compression waves because the molecules of air are compressed.
How is sound energy carried away from a drum?
Sound energy is carried away from a drum through the vibration of the drumhead, which creates compressional waves in the air. These waves travel as sound waves to reach our ears, where they are converted into nerve impulses that our brain interprets as sound.
Which kind of waves are sound waves?
compressional waves they swerve up and down

What waves causes compressional waves caused by colliding air molecules?
Sound Waves
The speaker on your cell phone creates it by vibrating the air to your ear in the form of compression waves?
sound
What and how are compressional waves formed?
by seismographic sound and vibrations
