15 Reasons Why You Shouldnt Overlook Planar Magnetic

How a Planar Magnetic Diaphragm Headphone Driver Works
In the past, dynamic drivers used a voice coil attached at the center of the dialephragm, which is conical. When an electrical signal passes through a voice coil the diaphragm is moved.
However, the force that is exerted is limited to a tiny area, making it difficult to allow different parts of the diaphragms to move at the same at the same time. This can result in distortions caused by breakup patterns.
Sound Detail
Many audiophiles want an authentic sound from their headphones. A good method to achieve this is through a planar magnetic diaphragm. This type of headphone works in a similar manner to cone drivers that are dynamic, but with a much more modern technology.
A planar diaphragm is a flat piece of material placed inside the frame of a headphone and constructed of a light, lightweight material. It is designed to be as uniform and flat as is possible. This ensures an even pressure distribution across the entire surface.
A planar magnetic diaphragm's flat design allows for a better soundstage. A more focused wavefront leads to better sound staging that can help locate the exact location of an vocal or instrument on the track. This is an important advantage over the more spherical wavefront that is typical of dynamic drivers.
A planar diaphragm is different from traditional dynamic drivers which employ a voice-coil that is anchored to the cone's center made of paper or plastic. Instead, it uses a series of magnets on each side of its flat surface. The electrical current flowing through the voice coil interacts with the magnets, causing the diaphragm to vibrate and produce sound. Because the entire diaphragm is driven simultaneously there is no breakup modes, mechanical filtering transmission delay, or local resonances that can negatively impact sound quality.
A diaphragm that is smooth and uniform can also accelerate more quickly than a more substantial, thicker one used in dynamic drivers. Physics laws state that force is proportional to acceleration and mass, which means the faster a diaphragm will move, the more force it exerts. This gives planar magnetic drivers a more accurate bass response and greater detail retrieval.
Of course, the advantages of the planar magnetic driver do not come without a price. Because they have a complicated motor system and a large diaphragm, they usually cost more than dynamic drivers, are bulkier and require a more powerful amplifier to perform effectively. Many manufacturers of planar magnetic headphones can take advantage of their technology to create premium headphones at competitive prices. Audeze LCD-4, HiFiMAN Susvara are a few examples.
High Sensitivity
Planar drivers differ from moving coil drivers that are used in the majority of headphones or IEMs in that they utilize a flat membrane instead of the conventional cone or dome membrane. As an electrical signal moves through, it interacts both with the magnets as well as the diaphragm to produce sound waves. The flatness of the diaphragm enables it to react quickly to sound and can produce many different frequencies, from bass to highs.
The main benefit of a planar magnetic design is that it's much more sensitive than other kinds of headphone driver, which may utilize a diaphragm that is up to a few times more powerful than a typical headphone. This gives you an amazing amount of clarity and dynamic range, allowing you to hear every tiniest detail that music can offer.
In addition, planar magnetic drivers produce an extremely uniform force throughout the diaphragm that eliminates breakup points, and provides an uncluttered sound that is free of distortion. This is particularly important for high-frequency sounds, where the sound can be distorted and distracting. In the FT5 the way this is achieved is by utilizing a highly advanced material called polyimide, which is both ultra-light and extremely robust, as well as a specialized conductor pattern that blocks inductance associated intermodulation distortion.
OPPO's planar magnetic drivers offer a superior phase coherence. This means that when the sound wavefront hits our ear, it's flat and unaltered. Dynamic drivers feature a spherical wavefront that disrupts the coherence of the signal, which result in less-than-perfect reconstructions high-frequency signals, particularly at high frequency. This is another reason that the OPPO headphones sound so real and natural, and extremely accurate.
Wide Frequency Response
Planar magnetic diaphragms have the ability to reproduce sounds at much higher frequencies than traditional dynamic drivers. This is because their thin and lightweight diaphragm moves extremely precisely. This allows them to offer high-quality transient response, which makes them a perfect option for audiophiles who need rapid responses from their speakers and headphones to reproduce the finest detail in music.
This flat structure also allows them to have a more uniform soundstage than headphones that have dynamic drivers that are coiled. In addition they are less susceptible to leakage that is the sound that escapes the headphones and out into the environment around you. In some cases this is a concern because it can distract listeners and affect their concentration while listening to music. In some instances this could be a problem since it can distract listeners and affect their concentration when listening to music.
Instead of using a coil behind a cone-shaped diaphragm planar magnetic headphones feature an array of conductors printed on the very thin diaphragm itself. The conductor is suspended between two magnets. When an electrical signal is applied to it, it transforms into electromagnetic energy and makes the magnetic forces that are on either side of the diaphragm interact with one another. This is what causes the diaphragm vibrate, creating a sound wave.
The low distortion is due to the consistent movement of the thin, lightweight diaphragm as well as the fact that force is evenly distributed across its surface. This is a significant improvement over traditional dynamic drivers which are known to cause distortion at high levels of listening.
Certain high-end headphones employ the old-fashioned moving coil design. However, most HiFi audiophiles are now embracing this long-forgotten technology to create a new generation of planar magnetic headphones that sound incredible. Some of these models require a high-end amp to power them. For those who can afford it, they can provide an experience unlike any other headphone. They offer a rich and detailed sound that is free of distortion that can be found in other headphone types.
Minimal Inertia
Due to their construction they can move faster and are lighter than conventional drivers. They reproduce audio signals with greater accuracy and can be tuned to a wider range. They also provide a more natural sound and have less distortion than traditional dynamic speakers.
The dual rows in a planar magnet driver produce the same and uniform force across the entire diaphragm surface. This reduces unnecessary and unwanted distortion. what are planar magnetic drivers can be controlled better because the force is evenly distributed. This allows the diaphragm be able to move in a precise pistonic motion, which results in precise and smooth reproduction of music.
Planar magnetic drivers are also capable of achieving very high levels of performance with very little weight, which makes them ideal for use with portable headphones. In addition, they can be produced to have a wide range of frequencies, from deep bass to high-frequency sounds. Audio professionals love them due to their wide frequency response and accurate sound.
Planar magnetic drivers differ from dynamic drivers that utilize coils to push the diaphragm. They do not have any mechanical parts which can cause distortion. This is due to the fact that the flat array of conductors rests directly on the diaphragm instead of in a coil behind it.
In contrast, the thin and lightweight diaphragm inside a planar magnetic driver may be driven by a powerful magnetic field with no loss of energy. In the end, the diaphragm can be driven with an even pressure, which prevents it from deforming and producing distortion.
The moment of inertia describes the resistance to the rotation of an object. The formula I = mr2 may be used to calculate it. The shape of an object affects its moment of inertia minimum. Thicker and longer objects have lower moments of inertia.
