Question: How Much Do You Know About Planar Magnetic Driver?
The Benefits of a Planar Magnetic Driver

Planar magnetic drivers are commonly used in the top headphones and IEMs. It offers many advantages that allow it to distinct from other balanced or dynamic armature drivers.

However the planar driver has certain disadvantages that are important to take note of. These include their higher cost and the need for an amplifier to drive them.

Ultra-thin diaphragms

Every sound we hear - from the loudest cymbal crashing to the tiniest rumble on a bench for a piano - is portrayed by an intricate turbulent wave of pressure. The driver of a high-quality headphone has to reproduce these waves accurately without distortion or omitting any details. This requires a light diaphragm with a thin, smooth surface that can move quickly and respond to a variety of frequencies.

Planar magnetic drivers use a flat diaphragm that is covered by a conductive layer and floats between magnets. This allows them to create an uniform field of magnetic energy across the entire diaphragm which reduces distortion.

This approach, however creates additional challenges like the possibility of membrane resonance issues and airflow turbulent within the grid-like magnetic arrays. These issues could result in the frequency of mechanical resonance in the diaphragm which is a lot higher than the input frequency, which reduces the sensitivity of a voice pressure sensor.

Using a patented technology called 'Spherical Acoustic Structure' (SAS), Final was capable of overcoming these limitations with the D8000 by using a single piece of material that is both diaphragm as well as conductor. This design was inspired by ribbon speakers and their spherical conductors. However, it was more cost-effective for headphones because of its dimensions and power requirements.

A ringing sound is a different problem that many planar magnetic designs face. This happens when low-frequency and high-frequency bass notes are played. This is due to a mismatch between the force of the magnet that is applied to the diaphragm compared to the natural flexing of the diaphragm.

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

Superior transient response

While the basic operation of planar magnetic drivers is the same as traditional dynamic drivers, the method by which they generate sound waves is different. The primary difference is that in a planar magnetic driver, the conductor is laid out on the diaphragm in a 2D flat pattern, instead of a coil centered around the diaphragm in a cone shape. Conductors can react to magnetic fields both on the diaphragm's edges and generate sound waves very accurately. This technology eliminates the necessity for voice coils which can change their impedance based on frequency, which results in distortion-free music.


In addition that, planar magnetic drivers tend to be more durable and lighter than traditional drivers, since they do not have moving parts that wear out over time. They are also less prone than conventional drivers to harmonic distortion which can degrade the quality of audio. They have a quicker reaction time and are able to reproduce sounds faster.

The huge surface area of the diaphragm planar however, requires more power in order to move it and create sound waves. This is why these headphones require an amplifier for headphone that can be able to drive them at a sufficient level. This additional cost and weight can be a turnoff for certain listeners.

Another benefit of planar magnetic drivers is that they produce an expansive soundstage that can be more spacious than conventional dynamic headphones. simply click the up coming website is because the huge, flat diaphragm moves more uniformly to create a planar sound wavefront, instead of a narrow and spherical wavefront, which is typical of dynamic drivers. This is an important characteristic of headphones that planar and gives a full-bodied listening experience.

Audio reproduction that is natural and faithful

Planar magnetic drivers provide a more natural and faithful sound reproduction than traditional driver models. Planar magnetic drivers generate equal magnetic forces using two rows of magnets unlike traditional dynamic drivers that have a cone-shaped membrane that is vibrating. This causes the diaphragm to move in a wave-like motion which prevents distortion. They can also reproduce music with a wider frequency range - from the lowest lows to highest highs which makes them a great choice for music enthusiasts and sound professionals.

The diaphragm is thin and flexible. of a planar magnetic driver is able to move much more quickly than traditional dynamic drivers, allowing it to respond to changes in the sound signal and provide an precise reproduction. The absence of a coil behind the diaphragm reduces the chance that mechanical components will meet up with each and cause distortions at higher volume.

The diaphragm is able to easily move large volumes of air to reproduce bass frequencies. The diaphragm's size and its flexibility are vital in generating the rich bass that you hear in your music. Dynamic drivers on the other hand, tend to be small and stiff, making it difficult for them to stand up to the high-speed movements required to reproduce bass.

Despite the advantages associated with planar magnetic drivers, they are not as popular in headphones and IEM products as dynamic driver models because of their high price and complicated design. This is partly because they require amplifiers to drive them, which limit their portability and ease of use. However, they are still well-liked by music lovers and critical listeners who value their outstanding performance and high audio quality.

Wide frequency response

Planar magnetic headphones utilize diaphragms that are flat and uniform to produce sound in a controlled and even manner. This results in a wide frequency response, which allows for accurate and precise reproduction of music. They are also renowned for their high transient response. This means that they are able to react quickly to audio signals and reproduce them as precisely as they can.

They do this by using an array of planar conductors that are spread across a thin diaphragm that is sandwiched between two magnets. When an electrical signal passes through this conductor array it is transformed into electromagnetic and interacts with the diaphragm's magnetic fields to produce the push/pull effect. This allows the diaphragm's magnetic fields interact with audio signals quickly, producing high-quality sound reproduction.

Another factor that makes these drivers so popular with audiophiles is their low distortion rate. They don't cause as much distortion due to the fact that they don't have the same moving components. They also have a lower resistance and are an unresistance load to amplifiers. This makes them simpler to drive.

Planar magnetic drivers are used in audio equipment that is of high-end quality due to their superior performance. However, this also means that they can be more expensive and require an amplifier which makes them less suitable for a 'grab and go' type of driver. Audiophiles will trade the extra cost and effort in exchange for the quality that these headphones provide. They are the best option for those who wish to enjoy a great listening experience.

Low distortion

The diaphragm inside a planar magnetic driver is very thin, meaning it can move at high speeds without losing control or breaking down. This allows for a highly precise and rapid response to sudden changes in the audio signal. This lets you hear details in music and makes them sound more natural and lifelike.

Another advantage of planar magnetic drivers is that they create an equal driving force across the entire diaphragm. This reduces distortion when you increase the volume. This is one of the primary reasons why planar headphones sound so good - dynamic drivers use thicker and heavier diaphragms that aren't capable of moving as quickly or at the same speed. They can even break down when forces are too strong or exceed their structural integrity limits, which causes diaphragms that are out of the sync.

On the other side the planar magnetic drivers generate an extremely powerful electromagnetic force that directly applies to the diaphragm. This eliminates the voice coil that is typically required in headphones that use traditional dynamic cone drivers. This allows for greater dynamics, a larger soundstage, and exceptional bass response.

Due to these advantages Due to these advantages, planar magnet drivers are regarded by many audiophiles as the most effective headphone driver. While they do have some concerns regarding power requirements and cost but their capability to provide exceptional sound quality makes them a great choice for those who demand the highest quality in audio reproduction. These drivers provide superior clarity and detail in all frequencies, except for low bass. Dynamic drivers are still preferred.
