Hey there! As a supplier of speakers and microphones, I've gotten tons of questions about how speakers work. It's a super interesting topic, and I'm stoked to break it down for you.
Let's start with the basics. At the heart of every speaker, there's a fundamental principle at play: the conversion of electrical signals into sound waves. It's like magic, but it's all science!
The Anatomy of a Speaker
First off, let's take a look at the main parts of a speaker. There are three key components: the cone, the voice coil, and the magnet.
The cone is usually made of paper, plastic, or metal. It's the part you can see on the front of the speaker. When the speaker is working, the cone vibrates back and forth, creating sound waves that travel through the air to your ears.
Next up is the voice coil. This is a coil of wire that's attached to the back of the cone. When an electrical current flows through the voice coil, it creates a magnetic field. And this is where the magnet comes in.
The magnet is a permanent magnet that creates a fixed magnetic field. When the magnetic field from the voice coil interacts with the fixed magnetic field of the magnet, it causes the voice coil to move. Since the voice coil is attached to the cone, the cone moves too, and that's how the sound is produced.
How the Electrical Signal Becomes Sound
So, how does an electrical signal turn into sound? Well, it all starts with the audio source. Whether it's your phone, a computer, or a music player, the audio source sends an electrical signal to the speaker.
This electrical signal is an alternating current (AC). That means the direction of the current changes back and forth very quickly. The rate at which the current changes is called the frequency, and it's measured in Hertz (Hz).
When the AC signal flows through the voice coil, it creates a magnetic field that constantly changes direction. This changing magnetic field interacts with the fixed magnetic field of the magnet, causing the voice coil to move back and forth. And as we know, when the voice coil moves, the cone moves too.
The movement of the cone creates pressure waves in the air. These pressure waves are what we hear as sound. The frequency of the electrical signal determines the pitch of the sound. A higher frequency signal creates a higher pitch sound, while a lower frequency signal creates a lower pitch sound.
Different Types of Speakers
There are several types of speakers, each with its own unique characteristics. The most common types are dynamic speakers, electrostatic speakers, and piezoelectric speakers.
Dynamic speakers are the most widely used type. They work based on the principle we just discussed, with a cone, voice coil, and magnet. They're great for a wide range of applications, from home audio systems to car speakers.
Electrostatic speakers use a thin, charged diaphragm instead of a cone. When an electrical signal is applied to the diaphragm, it moves back and forth, creating sound. Electrostatic speakers are known for their high - quality sound, but they're also more expensive and require special amplifiers.
Piezoelectric speakers use a piezoelectric material that changes shape when an electrical current is applied. This shape change causes the speaker to vibrate and produce sound. Piezoelectric speakers are small, lightweight, and energy - efficient, but they're not as good at reproducing low - frequency sounds.

And if you're into gaming, our 2.4G and BT Gaming Headphone is a must - have. It combines the benefits of 2.4G and Bluetooth connectivity, giving you a reliable and convenient audio solution for your gaming sessions.
The Role of Microphones
Now, let's talk a bit about microphones. Microphones do the opposite of speakers. While speakers convert electrical signals into sound waves, microphones convert sound waves into electrical signals.
The most common type of microphone is the dynamic microphone. It works in a similar way to a dynamic speaker. When sound waves hit the diaphragm of the microphone, it vibrates. The diaphragm is attached to a coil of wire that moves within a magnetic field, generating an electrical signal.
Condenser microphones are another popular type. They use a charged capacitor to convert sound waves into electrical signals. Condenser microphones are more sensitive and are often used in professional recording studios.
