The Benefits of a Planar Magnetic Driver
Planar magnetic driver is a type of audio technology that can be found in some of the top-quality headphones and IEMs. It has numerous advantages that set it apart from other balanced or dynamic driver types.
However planar drivers have some drawbacks that are important to take note of. They are more expensive and require an amplifier to be driven.
Ultra-thin diaphragms
Each 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 planar must reproduce these waves accurately, without missing any details or distortion of the audio. This requires a light, thin diaphragm that can be responsive and move quickly to a range of frequencies.
While dynamic drivers are powered by a voice coil attached to a conical diaphragm planar magnetic drivers are powered by a flat diaphragm skinned with a conductive film that floats between fixed magnets. This allows them to create a uniform magnetic field that covers the entire diaphragm and significantly reduce distortion.
This method, however, introduces additional challenges such as the possibility of membrane resonance issues and turbulent airflow within the grid-like magnetic arrays. These issues can result in a mechanical resonance frequency of the diaphragm that may be several times higher than the input frequency and reduces the sensitivities of the voice pressure sensor.
Final was able overcome these limitations using a single material that serves as a diaphragm, and a conductor. This solution was based on ribbon speakers with their spherical conductors. However, it was cheaper for headphones because of its size and power requirements.
Another issue that is common to all planar magnetic designs is a ringing sound that is seen on high-frequency and low-frequency bass notes. 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.
Final employed a thin polymer film dubbed Parylene to solve this problem. The material was chosen due to its superior mechanical flexibility, stability and thickness uniformity. These characteristics were essential to ensure that the thin, rigid film was able to be stretched without forming undesirable creases or wrinkles.
Superior transient response
The method by which planar magnetic drivers produce sound waves differs from traditional dynamic drivers. The main difference is that the conductor in a planar driver is laid out in a flat 2D pattern on the diaphragm rather than the coil being wrapped around a cone-shaped diaphragm. The conductor can react to magnetic fields both on the diaphragm's edges and generate sound waves that are extremely precise. This technology eliminates the need for a voice coil that could change its impedance depending on its frequency, resulting in a distortion-free reproduction of music.
In addition, planar magnetic drivers are more durable and lighter than conventional drivers due to the fact that they do not have moving parts that wear out over time. They are also less susceptible than conventional drivers to harmonic distortion, which can affect the audio quality. They also have a quicker response time and are able to reproduce transient sounds at a higher speed.
However, the large surface area of a planar diaphragm requires more power to move and create sound waves. These headphones require an amplifier for headphone that can be driven at a suitable level. Some listeners might not be interested in the extra weight and expense.
Another advantage of planar magnetic drivers is that they produce a large soundstage, which can be larger than conventional dynamic headphones. This is because the large, flat diaphragm moves more uniformly to create an asymmetrical sound wavefront rather than a focused circular wavefront typical of dynamic drivers. This is an important characteristic of headphones that planar and offers a more immersive listening experience.
Audio reproduction that is natural and accurate
Planar magnetic drivers offer more natural and precise sound reproduction than traditional dynamic driver models. Planar magnetic drivers generate equal magnetic forces by using two rows of magnets unlike conventional dynamic drivers which have a cone-shaped, curved membrane that oscillates. The diaphragm's movement is in a wavelike manner. This helps to avoid distortion. They also have the ability to reproduce music with a wider frequency range - from the lowest lows to the highest highs which makes them a perfect choice for music lovers as well as sound professionals.
The diaphragm, which is thin and flexible, in a planar magnet driver moves faster than an active driver. This allows it to react to changes in sound signals and provide accurate reproduction. The lack of a coil in the diaphragm also reduces the possibility that mechanical parts will come into contact with each other, planar driver which could cause distortions at higher volumes.
The diaphragm has the ability to easily move large volumes of air in order to reproduce bass frequencies. The diaphragm's size and flexibility is essential for producing the rich bass that you hear in your music. Dynamic drivers on the other hand tend to be smaller and stiff, which makes it difficult for them to withstand the high-speed fluctuations required to reproduce the bass.
Despite the advantages associated with magnetic drivers that are planar but they aren't as commonly used in headphones and IEM products as dynamic drivers due to their high price and complicated design. This is due to the fact that they require amplifiers to power them, which limit their mobility and ease of use. They are popular with music enthusiasts and critics who appreciate their exceptional quality of sound and outstanding performance.
Wide frequency response
Planar magnetic headphones employ diaphragms that are flat and uniform to produce sound in a steady and controlled manner. This results in a wide frequency response, delivering accurate and precise reproduction of music. They are also known for their high transient response. This means that they are able to react quickly to audio signals and reproduce them as precisely as is possible.
To do this, they employ a planar array of conductors spread across a thin diaphragm sandwiched between two magnets. When an electrical signal is transmitted to this conductor array, it becomes electromagnetic and interacts with the diaphragm's magnetic fields creating the push/pull effect mentioned earlier. This allows the diaphragm's magnetic field to interact with audio input quickly, resulting in superior sound reproduction.
Another thing that makes these drivers so loved by audiophiles is their low distortion rate. They aren't able to produce the same amount of harmonic distortion since they don't have the same moving parts. They also have a lower impedance than their counterparts and present a pure resistive load to amplifiers, which makes them easier to drive using a greater amount of power.
Due to their superior performance, planar magnetic drivers are typically used in higher-end audio equipment. They can be more expensive and require an amplifier to work, so they are not suitable for a 'grab-and-go' driver. However audiophiles are willing to sacrifice the additional expense and effort for the superior quality these headphones offer. They are regarded as a top choice for those who want an outstanding listening experience.
Low distortion
The diaphragm in a planar magnetic driver is very thin, which means it can move at high speeds without losing control or breaking. This allows for an extremely 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 real.
Another benefit of planar magnetic drivers is that they provide the same force of driving across the entire diaphragm which eliminates distortion at higher volumes. Planar magnetic headphones sound great since dynamic drivers employ diaphragms which are thicker and heavier that aren't able to move as quickly or with the same velocity. They can even break down when the forces are too high or exceed their structural integrity limits, which causes diaphragms that are out of the sync.
On the other side these drivers create an extremely powerful electromagnetic force that is directly applied to the diaphragm. This eliminates the need for a voice coil that is required in the majority of headphones with traditional dynamic cone drivers. This provides better dynamic range, a wider soundstage, and a superior bass response.
Because of these benefits, planar magnetic drivers are widely regarded as the best headphone driver for audiophiles. They do have some considerations regarding cost and power requirements, however their ability to provide superior audio quality is a great choice for those seeking the best quality audio reproduction. When compared to other kinds of headphones, these drivers have superior clarity and transparency in all frequencies except for bass frequencies (where dynamic drivers are typically still preferred).
