The Benefits of a Planar Magnetic Driver

Planar magnetic drivers are commonly used in the best planar magnetic headphones headphones and IEMs. It has numerous advantages that differentiate it from other balanced or dynamic armature driver types.

It is important to be aware of the drawbacks of planar drivers. They are more expensive and require an amplifier to be driven.

Ultra-thin diaphragms

Every sound we hear, from the most raucous sound of a cymbal crash to the most subtle creak of piano bench, is represented by a and turbulent pressure wave. The driver of a top headphone should reproduce these waves with precision without distortion or omitting any details. This requires a thin, diaphragm that is able to respond quickly to a wide range or frequencies.

Planar magnetic drivers employ an elongated diaphragm coated with a conductive coating and floats between magnets. This allows them create a uniform field of magnetism across the entire diaphragm and reduce distortion.

However, this approach poses other challenges such as the potential for problems with membrane resonance and airflow turbulence within the grid-like magnet arrays. These issues could lead to an amplitude of the mechanical resonance frequency of the diaphragm that is several times higher than the input frequency, thus reducing the sensitivity of voice pressure sensor.

With a patent-pending technology known as 'Spherical Acoustic Structure' (SAS), Final was able to overcome these limitations with the D8000 by using a single piece of material that functions as a diaphragm as well as conductor. This idea was inspired by ribbon speakers and their spherical conductor however, it was more affordable and practical for headphones due to its size and power requirements.

A ringing sound is another challenge that many planar magnetic designs face. This happens when high-frequency and low-frequency notes are played. This is caused due to a mismatch in the force of the magnetic field applied to the diaphragm and the natural flexing characteristics of the diaphragm itself.

To resolve this problem, Final used an ultra-thin, polymer film known as Parylene. The material was chosen due to its superior mechanical flexibility, stability, and uniformity of thickness. These qualities were crucial to ensure that a rigid, thin film would stretch without creating unwanted wrinkles or creases.

Superior transient response

The way that planar magnetic drivers generate sound waves is different from traditional dynamic drivers. The major difference is that in a planar magnetic driver, the conductor is laid out on the diaphragm in the form of a 2D flat pattern instead of a coil around the diaphragm in a cone shape. This allows the conductor to react to magnetic fields on both sides of the diaphragm and produce sound waves with high accuracy. This technology eliminates the requirement for voice coils that can change their impedance based on frequency, which results in distortion-free music.

Planar magnetic drivers are also lighter and more durable than traditional drivers due to the fact that they don't contain moving parts that wear out over time. They are also less prone to harmonic distortion which can lead to degradation in the audio quality. They also have a faster response time and can reproduce transient sounds at a higher speed.

However, the large surface area of a planar diaphragm requires more power to move and produce sound waves. These headphones require an amplifier to provide them with a sufficient level. Some listeners might not be interested in the additional weight and cost.

Another benefit of planar magnetic drivers is that they create a wide soundstage, which can be more spacious than traditional dynamic headphones. This is due to the fact that a large flat diaphragm produces an unidirectional wavefront, rather than the spherical wavefront that is focused typical of dynamic drivers. This is a major feature of planar headphones and gives a full-bodied listening experience.

Audio reproduction that is authentic and true

Planar magnetic drivers offer more natural and accurate sound reproduction than traditional dynamic driver models. Planar magnetic drivers create equal magnetic forces by using two rows of magnets unlike conventional dynamic drivers, which have a cone-shaped membrane that vibrates. The diaphragm is moved in a wave-like motion. This allows for less distortion. They also reproduce music in a wider range of frequencies, from the lowest lows all the way to the highest highs. This makes them an ideal option for sound professionals and music enthusiasts.

The diaphragm is thin and flexible. in a planar magnet driver is able to move faster than a dynamic driver. This allows it to react to changes in sound signals and produce precise reproduction. The lack of a coil behind the diaphragm reduces the chance that mechanical components will come into contact with each other, which could cause distortions at higher volume.

The diaphragm is able to effortlessly displace large volumes of air to reproduce bass frequencies. The size of the diaphragm and its flexibility are essential to produce the deep bass that you hear in your favorite music. Dynamic drivers however tend to be small and stiff, which makes it difficult for them to stand up to the high-speed fluctuations required to reproduce bass.

Despite the advantages that come with magnetic drivers that are planar, they are not as commonly used in headphones and IEM products as dynamic driver models due to their high cost and intricate design. Partly, this is due to the fact that they need amplifiers to be driven. This makes them less portable. They are still popular with music fans and critics who appreciate their superior quality of sound and outstanding performance.

Wide frequency response

Planar magnetic headphones use flat and uniform diaphragms to create sound in a steady and controlled manner. This leads to a wider frequency response, providing precise and accurate reproduction of music. They are also referred to for their superior transient response. This means they are able to react quickly and precisely to audio signals.

They accomplish this by employing a planar magnetic loudspeakers array consisting of conductors spread across a thin diaphragm sandwiched in between two magnets. When an electrical signal is transmitted through this conductor array it becomes electromagnetic, and interacts with the diaphragm's magnetic fields to create the push/pull effect. This allows the diaphragm's magnetic fields to interact with audio inputs quickly, resulting in high-quality audio reproduction.

Another thing that makes these drivers so loved by audiophiles is their low distortion rate. Since they don't contain the same moving parts as other headphone types which means they don't produce as many harmonic distortions. They also have a lower impedance than their counterparts, and offer an unresistive load to amplifiers, making them easier to drive with more power.

Planar magnetic drivers are commonly used in high-end audio equipment because of their superior performance. This makes them more expensive, and they require an amplifier and are therefore not suitable for a 'grab and go' driver. Audiophiles will trade the extra cost and effort in exchange for the quality that these headphones offer. They are considered to be a top choice for those seeking an outstanding listening experience.

Low distortion

The diaphragm inside a planar magnetic driver is extremely thin, which means it can move at high speeds without losing control or breaking down. This allows for an extremely accurate and quick response to sudden changes in the audio signal. This allows you to perceive the details of music more clearly, and makes them sound natural and lifelike.

Another benefit of planar magnetic drivers is that they produce the same force of driving across the entire diaphragm which prevents distortion when you increase the volume. This is one of the main reasons why planar headphones sound so good. Dynamic drivers have thicker and more heavy diaphragms, which are not capable of moving as fast or with the same acceleration. They can even break when forces are too strong or exceed their structural integrity limits, which causes diaphragms that are out of sync.

Planar magnetic drivers on the other hand produce powerful electromagnetic force that directly applies to the diaphragm. This eliminates the requirement for Best Planar Magnetic Headphones a voice coil which is commonly required in headphones that use traditional dynamic cone drivers. This helps to achieve better dynamics, a wider soundstage and a more powerful bass response.

Due to these benefits due to these benefits, planar magnetic drivers are regarded by many audiophiles as the most effective headphone driver. While they do have some concerns regarding the power requirements and costs however, their ability to provide superior sound quality makes them a great option for those who want the highest quality of audio reproduction. These drivers offer superior clarity and detail in all frequencies, excluding low bass. Dynamic drivers are preferred.
