how do planar magnetic headphones work a Planar Magnetic Diaphragm Headphone Driver Works

In the past, dynamic drivers had an attached voice coil at the center of a conical dialephragm. When electrical signal passes through the voice coil it causes the diaphragm to move.

However, the force that is exerted is limited to a tiny area and it's difficult for different points on the diaphragm to move at the same at the same time. This causes breakup modes that can lead to distortion.

Detailed Sound

Many audiophiles are looking to get an accurate sound from their headphones. One method to achieve this is with a planar magnetic diaphragm. This type of headphone driver operates in a similar fashion as dynamic cone drivers, but with much more modern technology behind it.

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

The flat shape of a planar magnetic diaphragm also allows for a more controlled soundstage. A more precise soundstage is created by a more precise wavefront. This can help you identify the exact location where a vocal or instrument is on the track. This is a major benefit over the more spherical waves typically of dynamic drivers.

Contrary to traditional dynamic drivers which utilize a voice coil attached to the center of a plastic or paper cone, a planar diaphragm utilizes a series of magnets on each side of its flat face. The diaphragm is vibrating and emits sound when the electrical current that flows through the voice coil interacts with these magnets. Because the entire diaphragm can be driven at the same time, there are no breakup modes mechanical filtering transmission delay or local resonances that can adversely affect sound quality.

A flat and uniform diaphragm can also accelerate more quickly than the larger and local heavier ones that are used in dynamic drivers. According to the laws of physics, force is proportional mass and acceleration. This means that the greater the speed at which a driver's diaphragm is moved, the more force they exert. This results in planar magnet drivers having an improved response to bass as well as superior detail retrieval.

Of course, the advantages of the planar magnetic driver do not come at a cost. They're more expensive than dynamic drivers since they feature a huge diaphragm as well as a complex motor. They also require a more powerful amplifier to work efficiently. Many planar magnetic headphone makers can take advantage of their technology and create high-performance headphones at a price that is competitive. 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 employ a flat membrane instead of a conventional cone or dome membrane. As an electrical signal passes, it interacts both with the magnets as well as the diaphragm, generating sound waves. The flatness of the diaphragm allows it to react very quickly to sound and can produce many different frequencies, from bass to highs.

The main benefit of the planar magnetic design is that it's more sensitive than other kinds of headphone drivers, which utilizes a diaphragm that is that is up to a few times larger than a typical headphone. This gives you an amazing quantity of dynamic range and clarity that allows you to hear every detail your music has to provide.

Additionally, planar magnetic drivers produce a very uniform driving force throughout the diaphragm that eliminates breakup points, and provides an uncluttered sound that is free of distortion. This is particularly important for high frequencies where the sound's breakups can be extremely audible and distracting. This is accomplished in the FT5 by using a material called polyimide which is both ultralight and durable, and also an advanced conductor design that eliminates distortion in intermodulation caused by inductance.

The OPPO's planar magnetic driver also have much better coherence in phase, which means that when a wavefront enters the ear canal, it has a perfectly flat and unaltered shape. Dynamic drivers feature a spherical wavefront that disrupts the coherence of the signal and result in less-than-perfect reconstructions high-frequency signals, particularly at high frequency. This is another reason why the OPPO headphones sound so authentic and natural, as well as incredibly accurate.

Wide Frequency Response

A planar magnetic diaphragm has the ability to reproduce sounds at greater frequency than conventional dynamic drivers, thanks to their diaphragm is thin and light in weight. moves in a very controlled way. This enables them to deliver high-quality transient response, which makes them a great choice for audiophiles who require rapid responses from their headphones and speakers to reproduce the finest detail in music.

This flat structure also allows them to have an even soundstage than normal headphones that use dynamic drivers that are coiled. Additionally they are less susceptible to leakage, which is the sound that escapes from headphone cups and enters the surrounding area. In some cases this can be a problem since it can distract the listener, and make them lose focus when listening to music. In other instances, however, it can be beneficial because it lets listeners enjoy their music in public environments without having to worry about disturbing others close by.

Instead of using the coil that is behind a diaphragm that's shaped like cones the planar magnetic headsets feature an array printed on a thin layer of the diaphragm itself. This conductor is then suspended between two magnets, and when an electrical signal is applied to the array, it turns into electromagnetic which causes the magnetic forces that are on either side of the diaphragm to interact each other. This is what causes the diaphragm to vibrate and produce an audio wave.

The low distortion is due to the consistent movement of the light, thin diaphragm and the fact that the force is evenly distributed across its surface. This is an improvement over traditional dynamic drivers which are known for producing distortion at very high levels of listening.

Some high-end headphones use the old-fashioned moving coil design. However, the majority of HiFi audiophiles are now adopting this long-forgotten technology to create a new generation planar closed back headphones magnetic headphones that sound incredible. Some of these models require a high-end amp to drive them. But for those who can afford it, they offer an experience unlike any other headphones. They deliver a deep and clear sound without the distortion you get with other types of headphones.

Minimal Inertia

As a result of their design they are extremely light and can move much faster than traditional drivers. They reproduce audio signals with greater accuracy and can be tuned to a larger range. They also produce a more natural sound and have less distortion than traditional dynamic speakers.

The dual rows of magnets inside a planar magnetic driver generate equal and uniform magnetic forces across the entire surface of the diaphragm. This eliminates any unwanted and unnecessary distortion. The lightweight diaphragm can be more easily controlled since the force is evenly dispersed. This permits the diaphragm to move in a precise pistonic motion, resulting in smooth and accurate music reproduction.

Planar magnetic drivers are capable of achieving very high levels of performance with the smallest weight, making them ideal for headphones that can be carried around. They can also be made to produce a wide range in frequencies, ranging from low frequency sounds to high-frequency ones. Audio professionals love them due to their large frequency response and precise sound.

In contrast to dynamic drivers, which make use of coils to push against the diaphragm and vice versa, 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 conductors' flat surface sits directly on the diaphragm instead of within a coil behind it.

A planar magnetic driver on the other hand, can drive a thin and lightweight diaphragm using a powerful magnetic force with no energy loss. The diaphragm, thin, light membrane is driven by the magnetic field, which exerts a constant pressure. This stops it from bending or causing distortion.

The moment of inertia is an important property that defines the object's resistance to rotation. It can be calculated from the formula I = mr2. An object's shape affects its minimum moment of inertia, with objects that are thinner and larger having lower moments of inertia compared to larger and thicker ones.
