The relationship between speakers and sound

In all sound systems, the final sound effect depends on the speakers. If the system has bad speakers, even if it is encoded on the most advanced storage device, using top-level playback equipment and power amplifier, even the best recording will be terrible.

A speaker of an audio system restores the electrical signals stored on CDs, tapes and DVDs to the original sound we can hear. In this article, we will learn more about how speakers work. We will also see the different designs of speakers and how these different designs affect the sound.

Loudspeakers have a profound impact on our culture and are amazing technologies. But in its core, it is a fairly simple device.

To know how the speakers work, you must first understand how the sound comes from. In your ear is a very thin skin called eardrum. When your eardrum vibrates, your brain feels the sound, this is how you can hear the sound. Rapid changes in air pressure can often cause your eardrum to vibrate. An object vibrates in the air to make sound (sound can also be transmitted through liquids and solids, but air is the medium through which we listen to speakers). When an object vibrates, it pushes the particles in the surrounding air. As a result, the particles in the air push the particles around them, and then the vibration pulse is transmitted through the air, like a messy journey.

To know how it happened, let's look at a simple vibrating object-the clock. When you hit the clock, the metal vibrates quickly, expanding and expanding. As it expands, it pushes the particles in the surrounding air. They are then accompanied by particle oscillations in front of them, and so continue. When the bell contracts, these particles are pulled back, causing the pressure to drop, which in turn pulls back more surrounding air particles, resulting in a pressure drop.

We reduced this pressure to underpressure. In this way, an oscillating object transmits pressure waves through the air. When this undulating wave reaches your ear, it causes the eardrum to vibrate back and forth. Our brain perceives it as sound.
