5 Things That Everyone Is Misinformed About In Regards To Planar Magnetic
How a Planar Magnetic Diaphragm Headphone Driver Works

Traditionally, dynamic drivers have an internal voice coil that is attached to the middle of a conical diaphragm. When electrical signal passes through the voice coil, it causes the diaphragm to move.

The force is applied to a tiny portion of the diaphragm and it is difficult to move multiple points at the same moment. This can lead to breakup patterns that can lead to distortion.

Sound Detail


Many audiophiles seek to get an accurate sound from their headphones. A good way to achieve this is through a planar magnetic diaphragm. This type of headphone driver functions in a similar way to dynamic cone drivers however, with more advanced technology behind it.

A planar diaphragm features a flat structure that's built into the headphone's frame and made out of a lightweight, thin film-like material. It's made to be as uniform as is possible, and its flat surface allows an evenly distributed pressure across the whole surface, which in turn improves sound clarity.

The flat design of a planar diaphragm magnetic diaphragm lets you control the soundstage. A more focused soundstage can be created by a more precise wavefront. This can help you determine the location of an instrument or vocal is located on the track. This is a major advantage over the more spherical waves typical of dynamic drivers.

In contrast to traditional dynamic drivers, which make use of a voice coil attached close to the center of a plastic or paper cone, a planar diaphragm makes use of magnets that are placed on its flat surface. The diaphragm vibrates and produces sound when the current that passes through the voice coil is absorbed by the magnets. The entire diaphragm can be driven simultaneously. This eliminates breakup modes mechanical filters, transmission delays and local resonances, which can have a negative impact on the sound quality.

A diaphragm that is flat and uniform is also capable of accelerating faster than the thicker and more heavy ones used in dynamic drivers. Physics' laws of physics say that force is proportional to mass and acceleration so the faster a diaphragm is able to move, the more force it exerts. This gives planar magnetic drivers better response to bass as well as superior detail retrieval.

Of course, the benefits of a planar magnetic driver don't come without a price. They are more expensive than dynamic drivers since they have a large diaphragm and a complex motor. They also require a larger amplifier to function properly. Many manufacturers of planar magnetic headphones are able to take advantage of their technology to create premium headphones at competitive prices. Audeze LCD-4, HiFiMAN Susvara are some examples.

High Sensitivity

The planar driver differs from the moving coil drivers found in the majority of headphones and IEMs, in that it utilizes a flat diaphragm, instead of a traditional cone or dome shaped membrane. When an electrical signal travels through, it interacts both with the magnets and diaphragm to create sound waves. The flat diaphragm is able to react quickly to sound, and produce a broad range in frequencies from lows to highs.

Planar magnetic headphones are more sensitive than other drivers for headphone which make use of diaphragms multiple times larger than a typical planar design. This lets you hear all the details in your music.

Planar magnetic drivers also provide an extremely consistent driving force across the diaphragm. This prevents breakup and creates an undistorted, smooth sound. This is particularly crucial for high frequencies, where the presence of breakup can be very audible and distracting. In the FT5 this is accomplished through the use of a sophisticated material called polyimide, which is both ultra-light and extremely robust, as well as a specialized conductor pattern that eliminates inductance intermodulation distortion.

The planar magnetic drivers of OPPO have much better phase coherence, meaning that when a wavefront hits our ear canal, it is an unaltered, flat shape. Dynamic drivers feature a spherical wavefront, which disrupts the coherence of the signal and results in less-than-perfect reconstructions of peak signals, especially when they are playing at high frequencies. magnetic planar sound very natural and authentic.

Wide Frequency Response

Planar magnetic diaphragms are able to reproduce sounds at higher frequencies than traditional dynamic drivers. This is due to their thin and lightweight diaphragm moves extremely precisely. This allows them to provide excellent transient response, which makes them an exceptional option for audiophiles who need rapid responses from their speakers and headphones to reproduce the finest nuances in music.

This flat design provides a more even soundstage than traditional headphones that use coiled dynamic driver. They are also less susceptible to leakage - the sound that escapes from the headphones into the environment. In certain situations this is a concern because it can distract listeners and alter their concentration when listening to music. In other cases however, it can be beneficial because it lets listeners enjoy music in public environments without worrying about disturbing other people near by.

Instead of using a coil behind a diaphragm that's shaped like a cone, planar magnetic headsets have an array printed on a thin film of the diaphragm itself. The conductor is suspended in between two magnets, and when an electrical signal is applied to this array, it turns into electromagnetic which causes the magnetic forces on the opposite side of the diaphragm to interact with each other. This is what causes the diaphragm to vibrate, creating the sound wave.

The low distortion is due to the uniform movement of the thin, lightweight diaphragm and the fact that the force is evenly dispersed across its surface. This is a major improvement over traditional dynamic drivers which can cause distortion when listening to high volumes.

Some premium headphones still employ the old school moving coil design, but the majority of HiFi audio enthusiasts are now using a technology that was long forgotten and a new generation of amazing sounding planar magnetic headphones. Some of these models are extremely expensive and require a top-of-the-line amplifier to run them however for those with the money, they provide an incredible experience that is unlike any other headphone. They provide a full, detailed sound that is free from the distortion inherent in other headphone models.

Minimal Inertia

Due to their construction the diaphragms of planar diaphragms move faster and are less heavy than conventional drivers. This means that they reproduce audio signals with greater precision and can be tuned for greater frequency ranges. They also give an authentic sound with less distortion than traditional dynamic loudspeakers.

The dual rows of magnets in a planar magnetic driver create equal and uniform magnetic forces across the entire diaphragm's surface. This eliminates unwanted and unnecessary distortion. The diaphragm that is lightweight is more manageable since the force is evenly distributed. This allows the diaphragm to vibrate in a perfectly pistonic motion, which results in an accurate and smooth music reproduction.

Planar magnetic drivers are capable of achieving very high levels of performance while carrying very little weight, which makes them ideal for headphones that can be carried around. They can also be made to provide the widest range of frequencies, ranging from deep bass to high-frequency sounds. Audio professionals love them for their large frequency response and precise sound.

Planar magnetic drivers are different from dynamic drivers that utilize coils to push the diaphragm. They don't contain any mechanical components that could cause distortion. This is due to the fact that the conductors' flat array is placed directly on the diaphragm rather than within a coil behind it.

In contrast the slim and light diaphragm of a planar magnetic driver may be driven by a powerful magnetic field with no loss of energy. The diaphragm, which is a thin, lightweight membrane is driven by an electric field that creates an unchanging pressure. This stops it from bending or causing distortion.

The moment of inertia is the resistance to the rotation of an object. It can be calculated using the formula I = mr2. The shape of an object influences its minimal moment of inertia. Longer and smaller objects have lower moments of inertia.
