Understanding The Basics: How Do Speakers Work?
Speakers are complex devices that convert electrical signals into sound waves. In order to understand how to test a speaker, it is important to have a basic understanding of how they work. When an audio signal is sent to a speaker, it passes through a coil of wire called the voice coil. The voice coil is surrounded by a permanent magnet. When the audio signal passes through the voice coil, it creates a magnetic field that interacts with the permanent magnet, causing the voice coil to move back and forth.
Attached to the voice coil is a diaphragm or cone, which is responsible for producing sound waves. As the voice coil moves, it causes the diaphragm to vibrate, producing sound. The speed and distance that the voice coil moves determines the volume and frequency of the sound produced.
In order to test a speaker, it is important to understand this basic concept. By measuring the electrical properties of the speaker, such as impedance or resistance, and the mechanical properties, such as resonance frequency, you can determine if the speaker is functioning properly and producing accurate sound.
