How a Planar Magnetic Diaphragm Headphone Driver Works

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

However, the force exerted is limited to a small area, making it difficult to allow different parts of the diaphragm to move at same at the same time. This can lead to breakup patterns that can lead to distortion.

Sound Detail

Many audiophiles are looking to get a detailed sound from their planars headphones. This can be achieved with a planar diaphragm. This type of headphone driver works similarly to dynamic cone drivers, but with much more modern technology behind it.

A planar diaphragm is a flat structure placed inside the headphone's frame and constructed of a light, lightweight material. It's designed to be as homogeneous as possible, and its flat surface allows for an uniform distribution of pressure across the whole surface which improves the clarity of sound.

A planar magnetic diaphragm's flat design provides a greater soundstage. A more precise wavefront can result in better sound staging that can help pinpoint the location of a instrument or vocal on the track. This is a major advantage over the more spherical wavefront typically of dynamic drivers.

In contrast to traditional dynamic drivers, which utilize a voice coil located close to the center of a paper or plastic cone, a planar diaphragm utilizes magnets that are placed on its flat surface. The electrical current flowing through the voice coil interacts with these magnets, Planars Headphones causing the diaphragm, which causes it to vibrate and create sound. The entire diaphragm is driven simultaneously. This eliminates breakup modes mechanical filters, transmission delays, and local resonances that can have a negative impact on sound quality.

A flat and uniform diaphragm is also capable of accelerating faster than the thicker and heavier ones that are used in dynamic drivers. The laws of physics state that force is proportional to acceleration and mass so the faster a diaphragm is able to move, the more force it exerts. This gives planar magnetic drivers a more precise bass response and better detail retrieval.

Of course, the advantages of a planar magnetic driver don't come without a price. Because they have a complicated motor system and large diaphragms, they generally cost more than dynamic drivers, are heavier and require a stronger amplifier to perform effectively. Many manufacturers of planar magnetic headphones can take advantage of their technology and design premium headphones at competitive prices. Some examples include the Audeze LCD-4 and HiFiMAN Susvara.

High Sensitivity

Planar drivers differ from the moving coil drivers used in most headphones or IEMs in that they employ a flat membrane instead of a traditional dome or cone shaped membrane. As an electrical signal moves through it, it interacts with the magnets as well as the diaphragm to produce sound waves. The diaphragm with a flat surface is able to respond quickly to sound, and it can produce a wide range in frequencies from lows to highs.

Planar magnetic headphones are more sensitive than other drivers for headphone, which can use diaphragms up to many times larger than a typical planar design. This results in an exceptional quantity of dynamic range and clarity which allows you to appreciate every tiniest detail that music has to provide.

Planar magnetic drivers also provide an extremely constant driving force throughout the diaphragm. This prevents breakup, and creates a smooth, distortion-free sound. This is particularly crucial for high-frequency sounds where the sound can be distorted and distracting. This is achieved in the FT5 by making use of a material called polyimide which is both ultralight and durable, as well as an advanced conductor design which eliminates distortion of intermodulation caused by inductance.

The planar magnet drivers of OPPO have a much better phase coherence. This means that when an audio wavefront strikes our ear, it is flat and unaltered. Dynamic drivers however they have a spherical-shaped wavefront that disrupts this coherence and leads to less-than-perfect signal peak reconstructions particularly Immerse yourself in sound with Kinera Gumiho high frequencies. This is another reason for why the OPPO headphones sound so real and natural, and extremely precise.

Wide Frequency Response

A planar magnetic diaphragm can be used to reproduce sounds using wider frequencies than conventional dynamic drivers, Planars headphones thanks to the fact that their diaphragms are thin and lightweight. is moved in a controlled way. They can provide an excellent transient response. This makes them a great choice for audiophiles looking for headphones and speakers that reproduce the most precise details of music.

The flat design gives them a more even soundstage than headphones that utilize a dynamic driver coiled. Additionally, they are less prone to leakage which is the sound that escapes from headphone cups and into the surrounding environment. In some cases, this is a problem because it can distract listeners and disrupt their concentration when listening to music. In other cases however, it can be beneficial as it allows listeners to enjoy their music in public areas without worrying about disturbing other people close by.

Instead of using a coil behind a diaphragm that is shaped like a cone Planar magnetic headsets comprise an array printed on a thin layer of the diaphragm itself. This conductor is suspended between two magnets. When an electrical signal is applied to it, the conductor becomes electromagnetic, and the magnetic forces on the opposite side of the diaphragm to interact with one another. This is what causes the diaphragm to vibrate and create an audio wave.

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

Some premium headphones still employ the old-fashioned moving coil design, but the majority of HiFi audiophiles are embracing a long-forgotten technology and a new generation of amazing sounding planar magnetic headphones. Certain models require a top-of-the-line amplifier to provide power. However, for those who are able to afford it, they offer an experience unlike any other headphones. They provide a rich and detailed sound without the distortion you get with other kinds of headphones.

Minimal Inertia

Because of their construction the diaphragms of planar diaphragms move faster and are less heavy than conventional drivers. They are able to reproduce audio signals with greater precision and can be tuned to a wider range. They also produce more natural sound and have less distortion than traditional dynamic speakers.

The dual rows Immerse in Pure Sound: Stealth Magnet Silver HiFi Headphones for Mobile a planar magnet driver create the same and uniform force across the diaphragm's surface. This eliminates any unwanted and unnecessary distortion. The diaphragm's weight can be controlled better because the force is evenly dispersed. This permits the diaphragm to move in an exact pistonic motion.

They also have the capability of achieving extremely high levels of performance while carrying very little weight. This makes them perfect for headphones that can be carried around. They can also be produced to have an array of frequencies, from deep bass to high-frequency sounds. Audio professionals love them due to their broad frequency response and precise sound.

Unlike dynamic drivers, which use coils to push against the diaphragm, planar magnetic drivers have no mechanical components that could come into contact with one with each other, causing distortion. This is because the flat array sits on top of the diaphragm instead of in a coil behind.

In contrast the light and thin diaphragm of a planar magnetic driver can be driven by an extremely powerful magnetic field without any loss of energy. The diaphragm, thin, light membrane is driven by a magnetic field that exerts a constant pressure. This stops it from bending or causing distortion.

The moment of inertia is a crucial property that defines the object's resistance to rotation. It can be calculated using the formula I = mr2. The shape of an object affects its minimum moment of inertia with thinner and longer objects having lower moments of inertia than bigger and more robust ones.
