This Is The History Of Planar Magnetic
How a Planar Magnetic Diaphragm Headphone Driver Works

In the past, dynamic drivers used a voice coil that was attached to the center of a conical dialephragm. When an electrical signal is passed through the voice coil, it causes the diaphragm to move.

The force is only applied to a small portion of the diaphragm, and it's difficult to move several points at the same moment. This can cause distortions due to breakup modes.

Detail Sound

Many audiophiles seek to get an authentic sound from their headphones. This can be accomplished through the planar diaphragm. This kind of headphone functions in a similar manner to cone drivers that are dynamic, but with more modern technology.

A planar diaphragm features an elongated structure that is built into the headphone's frame. It's made out of a lightweight, thin film-like material. It's designed to be as homogeneous as it can be and its flat surface allows an even distribution of pressure across the entire surface which, in turn, improves sound clarity.

The flat shape of a planar diaphragm magnetic diaphragm lets you control the soundstage. A more precise wavefront results in better sound staging that can help pinpoint the location of a instrument or vocal on the track. This is a significant benefit over the more spherical wavefront that is typical of dynamic drivers.

A planar diaphragm is distinct from traditional dynamic drivers which employ a voice-coil that is anchored to the cone's central point composed of plastic or paper. Instead, it employs a series magnets on either side of its flat surface. The electric current that flows through the voice coil interacts with these magnets to cause the diaphragm to vibrate and produce sound. The entire diaphragm is controlled simultaneously. This eliminates breakup modes mechanical filters, transmission delays, and local resonances that can have a negative effect on sound quality.

A diaphragm that is flat and uniform can also be accelerated more quickly than the larger and more heavy ones used in dynamic drivers. The laws of physics state that force is proportional to mass and acceleration, which means the faster a diaphragm is able to move the more force it exerts. This results in planar magnetic drivers more precise bass response as well as better detail retrieval.

Of course, the advantages of the planar magnetic driver do not come without a price. They are more expensive than dynamic drivers due to the fact that they feature a larger diaphragm and a complicated motor. They also require a larger amplifier to work properly. Many manufacturers of planar magnetic headphones are able to take advantage of their technology to create high-performance headphones for competitive prices. Audeze LCD-4, HiFiMAN Susvara are a few examples.

High Sensitivity

Planar drivers differ from moving coil drivers used in most headphones or IEMs in that they use a flat membrane instead of the conventional cone or dome membrane. As an electrical signal passes through it, it interacts with magnets on both sides of the diaphragm. This creates sound waves by vibrating the diaphragm. The flat diaphragm is able to react quickly to sound, and it can produce a wide range in frequencies from lows to highs.

Planar magnetic headphones are more sensitive than other headphone drivers, which can make use of diaphragms multiple times larger than the typical planar design. This creates an incredible amount of dynamic range and clarity that allows you to hear every detail your music has to provide.

In addition, planar magnetic drivers produce an extremely uniform force across the entire diaphragm and eliminates breakup points and produces an uncluttered sound that is free of distortion. This is particularly important for high-frequency sounds in which the presence of breakups can be quite loud and distracting. In the FT5 this is accomplished by utilizing a highly advanced material called polyimide. It is both ultra-light and extremely strong, and a sophisticated conductor pattern that eliminates inductance associated intermodulation distortion.

The planar magnetic drivers of OPPO have much better phase coherence, which means that when a wavefront enters our ear canal, it's an unaltered, flat shape. Dynamic drivers have a spherical-shaped wavefront, which disrupts the coherence of the signal and result in less-than-perfect reconstructions high-frequency signals, particularly at high frequency. This is another reason for why the OPPO headphones sound so real and natural, and extremely accurate.

Wide Frequency Response

Planar magnetic diaphragms have the ability to reproduce sounds at higher frequencies than traditional drivers. This is due to their diaphragms are thin and light. moves very precisely. This allows them to provide high-quality transient response, which makes them an exceptional option for audiophiles who need rapid response from their headphones and speakers to reproduce the finest nuances in music.

This flat design provides a more even soundstage than traditional headphones that employ a dynamic driver that is coiled. In addition they are less susceptible to leakage, which is the sound that escapes from the headphones and out into the surrounding area. In certain situations, this could be a problem, as it can distract the listener, and make them lose focus when listening to music. In some cases, this can be a problem due to the fact that it can distract listeners and affect their focus while listening to music.

Rather than using a coil behind a cone-shaped diaphragm, planar headphones are made up of conductors that are printed on the thin film of the diaphragm. The conductor is hung between two magnets. When an electrical signal is applied to it, the conductor becomes electromagnetic, and the magnetic forces on each side of the diaphragm interact with each other. This is the reason why the diaphragm begins to vibrate, which creates an audio wave.

The low distortion is due to the uniform movement of the lightweight, thin diaphragm, and the fact that the force is evenly distributed across its surface. This is a major improvement over traditional dynamic drivers which are known to produce distortion at very high levels of listening.

Some premium headphones still employ the old school moving coil design, but most HiFi audio enthusiasts are now using a technology that was long forgotten and a new generation of incredible sounding planar magnetic headphones. Some of these models are extremely expensive and require a high-end amplifier to run them however, for those who can afford them they offer an exceptional experience that is unmatched by any other headphone. They deliver a deep and detailed sound without the distortion that is common with other headphones.

Minimal Inertia

Because of their construction, planar diaphragms can move faster and are lighter than conventional drivers. They reproduce audio signals with greater precision and can be tuned to a larger range. They also give an authentic sound with less distortion than traditional loudspeakers.

The two rows of magnets in a planar driver produce equal and uniform magnetic forces across the entire surface of the diaphragm. click through the next article reduces unnecessary and unwanted distortion. The diaphragm that is lightweight can be controlled better because the force is evenly distributed. This allows the diaphragm vibrate in an exact pistonic motion.

They are also capable of achieving extremely high levels of performance while carrying minimal weight. This makes them ideal for use as a portable headphone. Additionally, they can be made to provide a wide range of frequencies, from deep bass to high-frequency sounds. The wide frequency response and accurate sound reproduction make them a popular choice for audio professionals.


planar magnetic headphones audeze are different from dynamic drivers that use coils to push the diaphragm. They don't contain any mechanical parts which can cause distortion. This is due to the fact that the flat array sits on top of the diaphragm, rather than in a coil behind.

A planar magnetic driver on the other hand it can drive a thin and lightweight diaphragm using a powerful magnetic force with no energy loss. In the end, the diaphragm is driven with an even pressure, preventing it from deforming and producing distortion.

The moment of inertia is the resistance to rotation of an object. planar magnetic technology = mr2 could be used to determine it. The shape of an object affects its minimum moment of inertia. Longer and smaller objects have lower moments of inertia.
