20 Resources That Will Make You Better At Planar Magnetic
How a Planar Magnetic Diaphragm Headphone Driver Works

Typically, dynamic drivers comprise a voice coil attached to the middle of the conical diaphragm. When an electrical signal is passed through the voice coil it causes the diaphragm to move.

However, the force applied is limited to a small area, and it's hard to allow different parts of the diaphragm to move at the same time. This can result in distortions due to breakup modes.

Audio with a Detailed Sound

Many audiophiles want a detailed sound through their headphones. This can be achieved through a planar diaphragm. This type of headphone operates similarly to cone drivers that are dynamic, but with a much more modern technology.

A planar diaphragm is a flat piece of material embedded in the frame of a headphone and made of a thin and light material. It's designed to be as uniform and flat as possible. This allows for an even pressure distribution across the entire surface.

The flat design creates a more spacious soundstage. A more precise soundstage is made possible by a narrower wavefront. This helps pinpoint where an instrument or vocal is on the track. This is a significant benefit over the more spherical wavefront that is typical of dynamic drivers.

A planar diaphragm is different from traditional dynamic drivers which utilize a voice coil that is 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. The diaphragm vibrates and creates sound when the electrical current that flows through the voice coil interacts these magnets. The entire diaphragm is driven simultaneously. This removes breakup modes mechanical filters, transmission delays and local resonances, which can have a negative impact on the sound quality.

A diaphragm that is uniform and flat can also accelerate more quickly than a more substantial, thicker 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 the more power they are able to exert. This gives planar magnet drivers better response to bass and superior detail retrieval.

The advantages of a planar magnetic driver are not without cost. Because they have a complicated motor system and large diaphragm, they usually cost more than dynamic drivers, are heavier and require a more powerful amplifier to function properly. Many manufacturers of planar magnetic headphones benefit from 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 that are used in the majority of headphones and IEMs, in that it uses a flat diaphragm in place of a traditional cone or dome shaped membrane. As an electrical signal passes through it, it interacts with magnets on both sides of the diaphragm. It produces sound waves by bouncing the diaphragm. The diaphragm that is flat is able to respond quickly to sound and can produce a wide range of frequencies ranging from lows to highs.


The main benefit of the planar magnetic design is that it's more sensitive than other kinds of headphone drivers, which can use a diaphragm that is up to a few times larger than a standard planar headphone. This results in an exceptional amount of clarity and dynamic range that allows you to hear every detail your music has to provide.

In addition the planar magnetic drivers provide a very uniform driving force throughout the diaphragm that eliminates breakup points and produces a smooth sound that's free of distortion. continue reading this.. is particularly important for high-frequency sounds, where the sound can be distorted and distracting. In the FT5, this is achieved by using an advanced material called polyimide. It is extremely light and robust, as well as a sophisticated conductor pattern that blocks inductance associated intermodulation distortion.

The OPPO's planar magnetic driver also have a higher degree of phase coherence, meaning that when a wavefront enters our ear canal, it has an unaltered and flat shape. Dynamic drivers have a spherical wavefront, which alters the coherence of the signal and result in less-than-perfect reconstructions high-frequency signals, particularly at higher frequency. This is another reason that the OPPO headphones sound so authentic and natural, as well as extremely accurate.

Wide Frequency Response

A planar magnetic diaphragm can be used to reproduce sounds using greater frequency than conventional dynamic drivers due to the fact that their diaphragm is thin and light in weight. is moved in a controlled way. This enables them to deliver excellent transient response, which makes them a great choice for audiophiles that require rapid responses from their speakers and headphones to reproduce the finest nuances in music.

This flat design also allows them to have a more even soundstage than regular headphones that use coiled dynamic drivers. They are also less susceptible to leakage - the sound that leaks out of the headphones and into the environment. In certain situations, this could be a problem since it can distract the listener and make them lose focus while listening to music. In other situations, it can be beneficial because it lets listeners enjoy music in public environments without worrying about disturbing other people near by.

Instead of putting a coil behind a diaphragm that is shaped like a cone, planar magnetic headsets have an array printed on a thin film of the diaphragm. The conductor is hung between two magnets. When an electrical signal is applied, it becomes electromagnetic and causes the magnetic forces on each side of the diaphragm interact with one another. This is what causes the diaphragm to vibrate, creating a sound wave.

The low distortion is due to the consistent movement of the light, thin diaphragm, and the fact that the force is evenly dispersed across its surface. This is a significant improvement over traditional dynamic drivers that have been known to cause distortion at very high levels of listening.

Some high-end headphones use the old-school moving coil design. However, most HiFi audiophiles are now embracing this long-forgotten technology to create new generation of planar magnetic headphones that sound incredible. Some of these models are incredibly expensive and require a high-end amplifier to power them however for those with the money they offer an exceptional experience that's unrivalled by any other headphone. They provide a rich and detailed sound without the distortion that comes with other headphones.

Minimal Inertia

Due to their design, planar magnetic diaphragms are extremely light and move much more quickly than traditional drivers. They reproduce audio signals with greater accuracy and can be tuned to a greater range. They also provide an authentic sound and have less distortion than traditional dynamic speakers.

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. The diaphragm's weight can be more easily controlled since the force is evenly dispersed. This allows the diaphragm be able to move in a precise pistonic motion, which results in an accurate and smooth music reproduction.

Planar magnetic drivers are capable of achieving extremely high levels of performance with very little weight, which makes them ideal for portable headphones. They are also able to produce a range in frequencies, ranging from low frequency sounds to high-frequency ones. Audio professionals love them due to their broad frequency response and accurate sound.

Planar magnetic drivers differ from dynamic drivers which use coils to push the diaphragm. They do not have any mechanical parts which can cause distortion. This is due to the fact that the conductors' flat surface is placed directly on the diaphragm, instead of in a coil behind it.

A planar magnetic driver, however, can drive a small and light diaphragm by applying a tremendous magnetic force without any loss of energy. The diaphragm is an extremely thin and lightweight membrane is driven by an electric field that creates a constant pressure. This prevents it from bending or causing distortion.

The moment of inertia is a crucial property that describes an object's resistance to rotation. It is calculated using the formula I = mr2. The shape of an object affects its minimum moment of inertia. Longer and smaller objects have lower moments of inertia.
