How Do Drivers in Speakers Work?

To comprehend the operation of a speaker driver, one must first grasp the fundamentals of electromagnetism. Whenever an electric current flows through a conductor, it generates a magnetic field. Conversely, when a magnetic field is applied to a conductor, it induces an electric current.

This principle underlies the operation of speaker drivers. A typical driver comprises a coil of wire wound around a permanent magnet. When an audio signal is sent through the coil, it induces fluctuations in the magnetic field, causing the coil to oscillate. These oscillations are then transmitted to the speaker cone, which amplifies them and emits them as sound waves. This ingeniously simple design enables loudspeaker drivers to reproduce a broad spectrum of frequencies, from deep bass tones to high-pitched sounds.

Types of Tweeters Used in a Speaker

Dome Tweeters

Among the most prevalent tweeters in contemporary speakers, dome tweeters derive their name from their dome-shaped diaphragms, which vibrate to generate sound. Typically crafted from materials like silk, polyester, or aluminum, these domes are selected for their capacity to accurately reproduce high-frequency sounds.

Ribbon Tweeters

Utilizing a slender strip of metal, often aluminum or a specialized alloy, ribbon tweeters produce sound through vibrations. Suspended between two magnets, the metal strip oscillates when an electrical current courses through it, resulting in remarkably precise high-frequency sound reproduction.

Planar Magnetic Tweeters

Employing a thin, flat diaphragm composed of materials such as mylar or aluminum, planar magnetic tweeters are suspended between two magnets. Application of an electrical current induces vibration in the diaphragm, facilitating the production of intricately detailed high-frequency sounds.

Horn Tweeters

Harnessing a horn-shaped diaphragm, typically crafted from materials like titanium or aluminum, horn tweeters excel at delivering loud, crystal-clear high-frequency sounds.

Electrostatic Tweeters

Featuring a thin diaphragm coated with conductive materials such as gold or aluminum, electrostatic tweeters are suspended between two metal plates. Passage of an electrical current through the plates prompts vibration in the diaphragm, resulting in accurate, detailed high-frequency sound reproduction.

Compression Tweeters

Utilizing a compression driver, compression tweeters leverage a diaphragm and voice coil attached to a horn. Application of an electrical current to the voice coil sets the diaphragm vibrating, thereby agitating the air within the horn to produce loud, clear high-frequency sounds.

Air Motion Transformer (AMT) Tweeter

Air Motion Transformer (AMT) tweeters employ a folded diaphragm made from pleated polyester film, etched with conductive traces, and a neodymium magnet to generate sound. When an electrical signal is applied, the diaphragm compresses and expands akin to an accordion, causing air to oscillate and produce sound.

Components of Multimedia Speaker Driver

Driver(s): The driver serves as the core element responsible for generating sound waves in a speaker system. While a standard speaker features at least one driver, multiple drivers of varying sizes and types may be incorporated to handle different frequency ranges. As previously noted, the primary driver types include woofers, mid-range drivers, and tweeters, each comprising various components such as the cone, voice coil, spider, magnet, and basket.

Crossover Network: An integral electronic component, the crossover network partitions the incoming audio signal into distinct frequency bands and directs them to the appropriate drivers. This functionality is vital for ensuring that each driver receives frequencies tailored to its intended reproduction capabilities. Commonly, a speaker incorporates a crossover network separating signals into low, mid, and high-frequency components.

Enclosure: Serving as the housing for the drivers and crossover network, the enclosure assumes a critical role in preventing interference between sound waves emitted from the front and back of the drivers. Additionally, the enclosure influences the speaker's radiation pattern and frequency response, significantly impacting its sound quality. Enclosures are available in diverse shapes, sizes, and materials, with their design intricacies crucial for achieving optimal sound reproduction.

Terminals: Positioned on the rear of the speaker, terminals facilitate connection to an amplifier or receiver. These connectors, which may include binding posts, spring clips, or alternative types, typically accommodate bare wire, spade connectors, or banana plugs.

Multimedia Speaker Driver Materials

A diverse array of materials is employed in crafting speaker drivers, each exerting a notable influence on the speaker's sound quality. The following are among the most prevalent materials utilized for speaker drivers:

Paper: Widely employed for the cones of mid-range drivers and woofers, paper boasts lightweight construction, cost-effectiveness, and a capacity to produce a warm, natural sound. However, paper cones may exhibit susceptibility to distortion and degradation if exposed to moisture over time.

Polypropylene: This thermoplastic polymer finds common application in mid-range and woofer driver cones. Recognized for its lightweight nature, durability, and excellent damping properties, polypropylene contributes to balanced sound production with commendable midrange and bass response.

Kevlar: Known for its strength and resilience, Kevlar serves as a synthetic material ideal for mid-range and woofer driver cones. Capable of delivering tight, impactful bass and a smooth midrange, Kevlar enhances overall sound performance.

Aluminum: Renowned for its lightweight yet rigid properties, aluminum is frequently employed in mid-range and woofer driver cones. With aluminum, speakers can achieve clean, detailed sound reproduction characterized by robust midrange and bass response.

Titanium: Employed for tweeter driver domes, titanium is a lightweight, sturdy metal that excels in producing bright, detailed sound with exceptional high-frequency response.

Silk (Silk Dome): As a natural material utilized in tweeter driver domes, silk imparts a smooth, warm sound quality alongside excellent high-frequency response.

Beryllium: Found in high-end tweeter driver domes, beryllium is prized for its lightweight, rigid composition, enabling the production of supremely detailed, transparent sound with unparalleled high-frequency response.

Q7. What makes a good speaker driver?

The best woofers and midrange drivers have particularly stiff cones, often made from aluminum, titanium, carbon fiber, wood-fiber pulp, or a sandwich of multiple materials. The stiffer the cone, the less likely it is to produce distortion - and the clearer the sound is. 

Q8. Do more drivers mean better sound?

When shopping for headphones, especially IEMs, more drivers don't necessarily mean better sound quality. It's essential to focus on the quality of the drivers rather than the quantity.

Q9. Do drivers affect audio quality?

Do bigger drivers in earphones or headphones mean better audio quality? All other things being equal, bigger drivers generally equal more volume and more bass.

Q10. Why do speakers have multiple drivers?

No single driver is well suited to handle all sounds from 20 Hz to 20,000 Hz; multiple drivers are commonly used to be able to span the full spectrum. A speaker that handles the full frequency is called a full-range speaker.

Q11. What makes a speaker have good sound quality?

The easiest and most objective thing to listen for is clarity. One way to determine whether a speaker has excellent clarity is to play music you are very familiar with, a song or album where you know every note, beat and detail.

Q12. Do I need a driver for my speakers?

Without the proper audio driver installed, your speakers won't give off any sound. If you have audio issues - crackling music, games missing sound effects, audio not working on your apps - or if your Windows computer emits no sound at all, it's time to update your sound drivers.

Q13. How does driver size affect speakers?

Does speaker driver size matter? Yes. Bigger drivers produce a richer, more full-bodied sound, while smaller drivers tend to be more nimble and provide better detail. In addition, driver size affects power handling, meaning that larger speakers can handle higher levels of power without being damaged.

Q14. Does speaker driver size matter?

A larger driver size, such as 13mm, can generally produce more powerful and impactful bass, as it can move more air than a smaller driver size, such as 10mm. This can make the music sound fuller and more immersive, especially for genres such as hip-hop and EDM that rely heavily on bass.

Q15. How do drivers work in speakers?

A driver is the mechanical part of a loudspeaker or subwoofer, also called a transducer. The driver's function is to take the electrical energy of the audio signal and convert it to mechanical energy by moving air to create sound.

Q16. Are single driver speakers good?

Single driver speakers are most suitable for the more intimate genre and at moderate volume levels. This includes solo voice, small group jazz and 18th century classical and chamber music. For these genre, single driver speakers are superb. You will hear nothing better.

Q17. What does a speaker driver look like?

The driver consists of two primary parts, a fixed magnet at the core and a "voice coil" wound around a tube that sits around this magnetic core. The rear of the tube is fixed and the front is attached to a paper or plastic cone that is attached to the outer rim of the speaker.

Q18. Why are speaker drivers round?

The main reason is that a loudspeaker has physically to move a lot of air and that means the diaphragm has to move a relatively long way. This 'long throw' diaphragm movement requires a very flexible surround, and achieving that in a non-circular shape is a serious design headache.
