Relationship between speaker and sound

In all sound systems, the final sound effect is determined by the speaker. If the system is linked to a bad speaker, even in the most advanced storage devices for encoding, the use of top players and power amplifier, and then good recording will be very scary. A sound system of speakers, to restore the electrical signals stored on CD, tape, and DVD to the original sound we can hear. In this article, we'll learn how speakers work. We will also see speakers of different designs, and how these different designs affect the sound effect. The speaker has a profound influence on our culture, and it's amazing technology. But in its core, it is quite simple. Want to know how speakers work, you need to understand how the sound came from. In your ear is very thin skin called the eardrum. When the eardrum vibrates when you feel the sound of your brain, this is how you can hear the sound. Rapid changes in air pressure can often cause your eardrum vibration. An object in the air to vibrate in a sound (sound can be transmitted through the liquid and solid, but the air is the medium we listen to the speaker). When an object is vibrating, it pushes the particles in the air around them, and the particles in the air push them around the particles, and then pass through the air to pass through the vibration of the air, like a chaotic journey. To know how it is produced, we look at a simple vibrating object -- the clock. When you come, the rapid expansion of metal vibration, stretching. And when it expands, it pushes the particles in the air around it. They are followed by the particle oscillations in front of them, so that they are extended. When the bell is shrinking, the particles are pulled back, causing the pressure drop, and then pull back more of the surrounding air particles, resulting in a drop in pressure. We put this pressure into a less pressure. In this way, an oscillating object is transmitted through the air to the wave of a wave. When the rolling wave reaches your ears, causing ears before and after vibration. Our brain perceives it as sound.
