Over the years, people have tried many mechanisms to make the air move according to electrical signals. The three sound production methods are very effective and practical and can be used in commercial products. They are dynamic drivers, ribbon sensors, and electrostatic panels. Speakers that use dynamic drives are often referred to as box speakers because the drives are installed in box enclosures or cabinets. Ribbon and electrostatic speakers are called flat speakers because they are usually mounted on a flat open panel.

The most popular speaker technology is undoubtedly dynamic drive. Wireless speakers using dynamic drivers can be identified by their familiar cones and domes. The popularity of dynamic drivers is due to its many advantages: wide dynamic range, high power processing, high sensitivity, relatively simple design, and robustness. Dynamic drivers are also called point source sensors because the sound is generated from a point in space.

The dynamic speaker system uses a combination of dynamic drivers of different sizes. The low frequency is reproduced by the conical woofer. High frequencies are generated by tweeters, usually using small metal or fabric domes. Some speakers use a third dynamic driver, the intermediate frequency, to reproduce the frequency in the middle of the audio band.

Although the designs of these drives are very different, they work on the same principle. First, a simple explanation is that the current from the power amplifier flows through the driver's voice coil. This current forms a magnetic field around the voice coil, which expands and contracts at the same frequency as the audio signal. The voice coil is suspended in a permanent magnetic field generated by the magnet in the driver. The permanent magnetic field interacts with the magnetic field generated by the current flowing through the voice coil, alternately pushing and pulling the voice coil back and forth. Because the voice coil is connected to the driver's cone, this magnetic interaction pulls the cone back and forth to produce sound.
