Loud speaker usually has two electromagnets (or a permanent magnet and an electromagnet).
When an audio signal in the form of an electric signal with desired frequency is applied to both electromagnets in opposite direction at same time so that they act as magnets with same polarities facing. This makes them repel with the given frequency, thus producing sound.

Which of these is the most important element with regard to the creation of sound?
The vibration of air molecules is the most important element in the creation of sound. When an object vibrates, it causes the air molecules around it to vibrate, producing sound waves that travel through the air.
How does a cone vibrate?
A cone vibrates by oscillating back and forth in response to external forces or stimuli. The motion of the cone creates changes in air pressure, which produces sound waves that we can hear. The frequency and amplitude of the vibrations determine the pitch and volume of the sound produced.
Why is thunder are noise?
Thunder is the sound generated by the rapid expansion of air surrounding a lightning bolt due to the extreme heat generated. The intense heat causes the air to expand rapidly, creating a shockwave that we hear as thunder.
How does earth compactor work?
An earth compactor works by exerting pressure and force to compress and flatten soil, gravel, or asphalt surfaces. This process helps to increase the soil's density and remove air voids, resulting in a more stable and durable foundation for construction projects. The compactor vibrates or uses a heavy drum to achieve this compaction efficiently.
How does sound travel through gases?
Sound travels through gases as a series of compressions and rarefactions of the gas molecules. When an object vibrates, it creates pressure waves that move through the gas, causing neighboring molecules to also vibrate and transfer the sound energy. The speed of sound in gases depends on factors such as temperature, pressure, and the molecular weight of the gas.
What is the part of a loudspeaker that vibrates to make sound?
a speaker uses a voice coil a coil copper wire and a magnet and pole to vibrate a cone

Which are the different types of loudspeakers?
1) Crystal Loudspeaker 2) Electrostatic (Condenser/Capacitor) Loudspeaker 3) Dynamic Loudspeaker
What is the vibrating part of loud speaker?
The cone of a speaker is what vibrates to make sound. In some hard speakers with a rigid cone-shaped horn, a flexible diaphragm vibrates. Withut the vibration, you get no sound.
What is the duration of Loudspeaker film?
The duration of Loudspeaker - film - is 2.02 hours.
What is in a longitudinal wave?
When something vibrates, like a loudspeaker, it compresses the air and increases the pressure of the air when it moves out. When the loudspeaker moves in it creates a partial vacum and a decrease in air pressure. The increase/decrease in air pressure is propagated thru the air (or any medium),as a longitudinal wave, by pushing the air in front of it. The part of the cycle which produces the decrease in pressure is called a "rarefacation" of the air.
