There Are A Few Reasons That People Can Succeed On The Planar Magnetic Industry
How a Planar Magnetic Diaphragm Headphone Driver Works

In the past, dynamic drivers featured a voice coil that was attached to the center of a conical dialephragm. When electrical signals pass through a voice coil the diaphragm moves.

The force is applied to a small portion of the diaphragm, so it's difficult to move several points at the same time. This causes breakup modes that can lead to distortion.

Audio with a Detailed Sound

Many audiophiles want a detailed sound through their headphones. One method to achieve this is through a planar magnetic diaphragm. This kind of headphone driver functions in a similar way to dynamic cone drivers however, with more advanced technology behind it.

A planar diaphragm is an elongated structure placed inside the headphone's frame and is made of a fine and light material. It's designed to be as homogeneous as possible, and its flat surface permits an even distribution of pressure across the whole surface which improves the clarity of sound.

The flat design creates a more spacious soundstage. A more precise soundstage is created by a more precise wavefront. This can help you pinpoint the exact location where a vocal or instrument is located on the track. This is a major benefit over the more spherical waves typical of dynamic drivers.

A planar diaphragm is distinct from traditional dynamic drivers that use a voice-coil attached to the center of a cone composed of plastic or paper. Instead, it utilizes a series magnets on either side of its flat surface. such a good point and creates sound when the electrical current that flows through the voice coil interacts with the magnets. Because the entire diaphragm is driven at the same time, there are no breakup modes mechanical filtering transmission delay, or local resonances which could adversely affect sound quality.

A diaphragm that is flat and uniform can also accelerate more quickly than a thicker, heavier one used in dynamic drivers. According to the laws of physics force is proportional mass and acceleration. This means that the faster a driver's diaphragm moves and the greater power they can exert. This gives planar magnetic drivers a more accurate response to bass and better detail retrieval.

The advantages of a planar magnetic driver are not without cost. They are more expensive than dynamic drivers because they feature a huge diaphragm and a complicated motor. They also require a stronger amplifier to work properly. Many planar magnetic headphone makers benefit from their technology and create high-performance headphones for competitive prices. Examples include the Audeze LCD-4 and HiFiMAN Susvara.

High Sensitivity

Planar drivers differ from the moving coil drivers found in many headphones or IEMs in that they utilize a flat membrane instead of a traditional dome or cone shaped membrane. When an electrical signal travels through it, it interacts with magnets on both sides of the diaphragm and produces sound waves by vibrating the diaphragm. The diaphragm with a flat surface is able to react quickly to sound, and can produce a wide range in frequencies from lows to highs.

A key benefit of the planar magnetic design is that it's more sensitive than other kinds of headphone driver, which can use a diaphragm that is up to a few times larger than a typical headphone. This allows you to hear all the details in your music.

Planar magnetic drivers also provide a very consistent driving force throughout the diaphragm. This prevents breakup, and creates an undistorted, smooth sound. This is particularly crucial for high-frequency sounds where breakups can be noticeable and distracting. In the FT5, this is achieved by utilizing a highly advanced material called polyimide, which is both ultra-light and extremely robust, as well as a sophisticated conductor pattern that eliminates inductance related intermodulation distortion.

OPPO's planar magnetic drivers offer a superior phase coherence. This means that when an audio wavefront strikes our ear, it is flat and unaltered. Dynamic drivers feature a spherical wavefront, which alters the coherence of the signal and result in less-than-perfect reconstructions high-frequency signals, particularly when they are playing at high frequencies. This is another reason for why OPPO's headphones sound so realistic and natural, and incredibly accurate.

Wide Frequency Response

A planar magnetic diaphragm is able to reproduce sounds using wider frequencies than conventional dynamic drivers, thanks to the fact that their lightweight and thin diaphragm moves in a very controlled way. They can provide an excellent transient response. This makes them a perfect choice for audiophiles looking for headphones and speakers that reproduce the finest details of music.

This flat design also gives them a more uniform soundstage than regular headphones that use dynamic drivers that are coiled. In addition they are less susceptible to leakage which is the sound that escapes from the headphone cups and enters the environment around you. In some cases this can be a problem as it can distract the listener and cause them lose focus while listening to music. In certain situations it can be a problem because it can distract listeners and alter their focus when listening to music.

Rather than using a coil that is placed behind a cone-shaped diaphragm planar magnetic headphones have conductors that are printed on the thin diaphragm. This conductor is then suspended between two magnets and when an electrical signal is applied to this array, it turns into electromagnetic and causes the magnetic forces on either side of the diaphragm to interact with each with each other. This is the reason why the diaphragm begins to vibrate, creating a sound wave.

The low distortion is due to the uniform movement of the thin, lightweight diaphragm as well as the fact that force is evenly dispersed across its surface. This is a major improvement over traditional dynamic drivers that are known to produce distortion when listening to high volumes.

Some high-end headphones still use the old-fashioned moving coil design, however the majority of HiFi audiophiles are adopting a long-forgotten technology and a new generation of incredible sounding planar magnetic headphones. Some of these models require a high-end amp to provide power. But for those who are able to afford it, they offer an experience that is unlike any other headphone. They offer a rich clear, clear sound that's free of distortion that can be found in other types of headphone.

Minimal Inertia

Due to their design they can move faster and are lighter than traditional drivers. This means that they reproduce audio signals with greater precision and can be tuned to a wider range of frequencies. They also produce natural sound with less distortion than traditional loudspeakers.


The dual rows of magnets in a planar magnetic driver create equal and uniform magnetic forces across the entire surface of the diaphragm. This prevents unwanted and unnecessary distortion. Because the force applied to the diaphragm's light weight is evenly distributed and evenly, it can be controlled more precisely. This allows the diaphragm vibrate in an exact pistonic motion.

They are also capable of achieving extremely high levels of performance while carrying very little weight. This makes them ideal for portable headphone. They are also able to produce a range in frequencies, from low-frequency sounds to high-frequency ones. The high frequency response and the precise sound reproduction make them a popular choice among audio professionals.

In contrast to dynamic drivers, which use coils to push against the diaphragm, planar magnetic drivers have no mechanical components that could come into contact with each with each other, causing distortion. This is due to the fact that the flat array of conductors sits directly on the diaphragm instead of being enclosed in a coil behind.

In contrast, the thin and lightweight diaphragm in a planar driver can be driven by a powerful magnetic field without any loss of energy. As a result, the diaphragm is driven with an even pressure, preventing it from bending and causing distortion.

The moment of inertia is an important property that describes the object's resistance to rotation. The formula I = mr2 can be used to determine it. The shape of the object influences its minimum moment of inertia with longer and thinner objects have lower moments of inertia than bigger and more robust ones.
