introduction :
The speaker, this small but powerful device, is the essential element that converts electrical signals into tangible sound waves. Imagine a world without sound, without music, without conversations, without laughter... Speakers are what give us the ability to enjoy all these sounds and embody them in our daily lives. In this article, we will learn about the components of a speaker and how it works, the different types of speakers, and their importance in our lives.
Speaker components and how it works :
The amplifier basically consists of three main parts:
- Magnet: Generates a constant magnetic field.
- Voice coil: A wire wrapped around a core of electrically conductive material.
- Cone: It is a flexible membrane that moves in response to changes in electric current.
When an alternating current (AC) passes through the vocal fold, a changing magnetic field is generated around it. This changing magnetic field interacts with the static magnetic field of the magnet, causing the vocal fold to move back and forth. This movement in turn vibrates the cone, which compresses the surrounding air and produces sound waves.
Types of speakers :
There are many types of speakers, and each type has characteristics and features that make it suitable for certain uses. The most important of these types are:
- 12 Inch Bluetooth Speaker Rechargeable Battery 150W Portable with 2 Wireless Microphones

The importance of a loudspeaker in our lives :
Loudspeakers are used in many aspects of our daily lives. They are used in:
- Home appliances: such as televisions, radios, and computers.
- Audio systems: in homes, cars, and parties.
- Mobile devices: such as smartphones and tablets.
- Industry: In loudspeakers used in advertising and conferences.
Conclusion:
