The Driver Operation Principle

The operation of a moving coil driver relies on the interaction between the permanent magnet and the voice coil positioned within the driver. When the voice coil is connected to a power source with continuously changing current direction, it generates an induced magnetic field around the coil, altering its direction periodically. This induced magnetic field interacts with the magnetic field produced by the permanent magnet, resulting in repulsion or attraction forces that cause the voice coil to oscillate up and down.

As the current direction continuously changes, the voice coil reciprocates up and down in accordance with the frequency reversal of the current. Simultaneously, the diaphragm linked to the voice coil also moves correspondingly, displacing the surrounding air to create fluctuations in air density, subsequently producing sound. The frequency of the sound generated is directly proportional to the speed of current direction changes. This mechanism elucidates the functioning of the moving coil driver.

3 Most Common Types of Speaker Drivers

Horn Speakers

True to their name, horn loudspeakers feature an open, funnel-shaped structure reminiscent of a trumpet. Many may recognize this design from vintage phonographs, also known as gramophones. In early iterations, a flared horn served the dual purpose of amplifying sound generated by a vibrating diaphragm. Essentially, the horn transferred vibrations from the diaphragm to the air while amplifying them to enhance volume.

Cone Speakers

Cone speakers utilize the familiar geometry of a cone, commonly encountered in school geometry classes. This design is prevalent in the most popular forms of driver construction. A typical cone driver comprises a cone-shaped membrane with a central dust cap, a component that has no impact on sound quality. Sound reproduction relies on the membrane's function. Attached to a voice coil, the membrane moves in response to the magnetic field generated by electric current flowing through the coil in a magnetic field. This back-and-forth motion, known as excursion, distinguishes cone speakers as the most dynamic among the discussed driver designs, hence why this type of driver is sometimes referred to as a "dynamic loudspeaker."

Dome Speakers

Similar to horn and cone speakers, the name effectively describes the form of dome speakers. Generally concave and smaller than cone speakers, this design offers the advantage of providing a wider dispersion angle for the upper range, thereby mitigating the beaming tendency of higher frequencies.

Multimedia Speaker Driver Sizes

Drivers vary in size and function, typically categorized into three types based on the frequencies they reproduce:

• Tweeter Driver: These are designed to reproduce high-frequency treble sounds, typically above 2,000 Hz.
• Midrange Driver: These are responsible for reproducing midrange frequencies, typically ranging from 200 Hz to 2,000 Hz.
• Woofer Driver: These are specialized in reproducing low-frequency bass sounds, typically below 200 Hz.

Factors Influencing Driver Performance

Material

The material utilized in constructing a driver significantly influences its performance. Common materials include paper, plastic, and metal. Paper cones, being lightweight, often yield a warm, natural sound, albeit susceptible to distortion at higher volumes. Plastic cones, being more rigid, tend to produce clearer sound, albeit possibly lacking the warmth of paper. Metal cones, being the most rigid, typically deliver the most accurate sound, albeit at a higher cost.

Size

The size of the driver also impacts its performance. Larger drivers generally excel at reproducing lower frequencies, while smaller ones are better suited for higher frequencies. However, larger drivers may be more challenging to control, potentially leading to distortion. Thus, it's crucial to align the driver size with the enclosure's dimensions and the speaker's intended usage.

Shape

The driver's shape can also influence its performance. Conical drivers, the most prevalent, produce a natural sound but may distort at higher volumes. Dome-shaped drivers, offering greater rigidity, tend to produce clearer sound but may sacrifice the warmth of conical ones. Horn-shaped drivers, being the most rigid, often deliver the most accurate sound, albeit at a higher cost.

Maintaining and Repairing Speaker Drivers

Ensuring the optimal performance of your speakers involves maintaining and repairing speaker drivers as needed. Here are some tips to help you preserve the condition of your speaker drivers:

Regular Cleaning: Dust and dirt accumulation on the driver cones can compromise sound quality. Use a soft brush or cloth to delicately remove any dirt or dust from the cones.

Avoid Overdriving: Overdriving your speakers can result in damage to the driver cones. Be mindful not to exceed the recommended power levels for your speakers.

Check Connections: Loose or damaged connections may cause buzzing or crackling sounds. Regularly inspect the connections and ensure they are securely fastened.

Replace Damaged Drivers: If a driver is damaged, it's advisable to replace it. Attempting to repair a damaged driver may exacerbate the issue.

Repairing Damaged Cones: In cases of cone damage, professional repair may be feasible. However, this task should be entrusted to a qualified professional.

All the above parameters can be adjusted or customized according to customer requirements.

Q7. What is the purpose of the driver in a speaker?

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. The parts that comprise a driver are the cone, dust cap, spider, voice coil, magnets, frame and other supporting components dependent on the individual design. Drivers can take the form of a dome, cone, ribbon, or horn. The best speaker and subwoofer drivers are made with lightweight and rigid materials and precisely engineered to create effortless, crystal clear audio output that is unerringly faithful to the original source material.

Q8. 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.

Q9. 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.

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. How does driver size affect sound?

In general, the main difference between 10mm and 13mm drivers in True Wireless Stereo (TWS) earbuds is the size of the driver unit, which can affect the sound quality and bass response of the earbuds. 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. On the other hand, smaller drivers, such as 10mm, may be better suited for genres that require more precise and detailed sound, such as classical music or jazz. Smaller drivers may also provide better overall clarity and balance in the sound.

Q12. What is the efficiency of a speaker driver?

Most speaker specifications pertain to sensitivity. Efficiency is the percentage of acoustic energy radiated in all directions from a speaker, compared to the input of a given amount of power (3% to 4% efficiency is typical for a woofer). Given two speakers with identical sensitivity and the input of an identical amount of power, the speaker with wider dispersion is more efficient.

Q13. 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.

Q14. What is a speaker driver made of?

In order to create the foundation for great sound, great speaker drivers need to be made of a durable, lightweight, yet stiff material. There are a variety of different materials that are used in speaker drivers, including paper, metal (such as aluminum or titanium), polypropylene, beryllium and Kevlar.

Q15. What is the sensitivity of a speaker driver?

Sensitivity is the relationship between the wattage going into a speaker and the volume coming out of it measured, at a specific distance away from it. It's closely related to power handling and impedance. Sensitivity will tell us how loud a speaker will get with a given amplifier. To standardize sensitivity, it's a measure of the volume (in dB) at 1 meter away from a speaker when 1 watt of power is being fed into it. Speakers frequently have a sensitivity of around 87 dB. A speaker is considered excellent if it has a sensitivity rating above 90 dB.

Q16. What is sound driver size?

A headphone driver unit has a diameter between 20mm and 50mm. The size dictates the loudness of the headphone. But many people have a misconception that headphone drivers of a bigger size automatically produce better sound quality.

Q17. How many watts does it take to drive speakers?

If you like loud uncompressed music and your speakers are 90dB efficient, 200 Watts is likely plenty of power for you. If you only listen to light classical, jazz and don't expect them to rock the house, 50 Watts is adequate. Higher efficiency speakers, like horns, take very few Watts.
