How a Planar Magnetic Diaphragm Headphone Driver Works

In the past, dynamic drivers used 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.

The force is applied to a tiny portion of the diaphragm and it is difficult to move multiple points simultaneously. This can result in distortions caused by breakup patterns.

Sound Detail

Many audiophiles want to hear an accurate sound through their headphones. This can be achieved by using the planar diaphragm. This type of headphone operates in a similar way to cone drivers that are dynamic, but with a much more advanced technology.

A planar diaphragm has a flat structure that's integrated into the headphone's frame. It's constructed of a light, thin film-like material. It's designed to be as uniform as it can be, and its flat surface permits an even distribution of pressure across the whole surface, which in turn improves sound clarity.

A flat planar magnetic diaphragm's design creates a more spacious soundstage. A more focused wavefront leads to better sound staging, which can help you locate the exact location of an vocal or instrument on the track. This is a major advantage over the more spherical wavefront that is typical of dynamic drivers.

A planar earphones diaphragm is different from traditional dynamic drivers that employ a voice-coil that is anchored to the cone's center made of paper or plastic. Instead, it uses series magnets that are placed on either side of its flat surface. The electric current that flows through the voice coil interacts with the magnets to drive the diaphragm and produce sound. The entire diaphragm can be driven simultaneously. This eliminates breakup modes, mechanical filters, transmission delays, and local resonances that can have a negative impact on sound quality.

A diaphragm that is uniform and flat can also accelerate more quickly than a larger, more robust one used in dynamic drivers. The laws of physics state that force is proportional to mass and acceleration, which means the faster a diaphragm will move, the more power it can exert. This gives planar magnet drivers a more accurate response to bass as well as superior detail retrieval.

Of course, the advantages of the planar magnetic driver do not come without cost. 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 to create high-performance headphones at a price that is competitive. Audeze LCD-4, HiFiMAN Susvara are a few examples.

High Sensitivity

The planar driver is different from the moving coil drivers that are used in the majority of headphones and IEMs by using a flat diaphragm, instead of a dome-shaped or cone-shaped membrane. As an electrical signal moves through, it interacts both with the magnets and the diaphragm to produce sound waves. The flatness of the diaphragm allows it to react very quickly to sound and can produce a wide range of frequencies, from bass to highs.

Planar magnetic headphones are more sensitive than other drivers for headphone, which can make use of diaphragms many times larger than the typical planar design. This gives you an amazing amount of clarity and dynamic range which allows you to appreciate every detail your music can offer.

In addition, planar magnetic drivers produce an extremely uniform driving force throughout the diaphragm and eliminates breakup points and produces an uncluttered sound that is free of distortion. This is particularly important for high-frequency sounds, where breakup can be audible and distracting. This is achieved in the FT5 by using the polyimide material, which is both ultralight and extremely durable, and also an advanced conductor design that eliminates intermodulation distortion caused by inductance.

OPPO's planar magnetic drivers have a much better phase coherence. This means that when the sound wavefront hits our ear, it is flat and unaltered. Dynamic drivers have a spherical-shaped wavefront that disrupts the coherence of the signal and results in less-than-perfect reconstructions of the highest frequencies, particularly at higher frequencies. This is another reason for why OPPO's headphones sound so realistic and natural, as well as extremely accurate.

Wide Frequency Response

A planar magnetic diaphragm has the ability to reproduce sounds with much higher frequencies than traditional dynamic drivers, thanks to the fact that their lightweight and thin diaphragm moves in a very controlled way. This allows them to provide high-quality transient response, which makes them a perfect choice for audiophiles who require quick responses from their speakers and headphones to reproduce the finest detail in music.

This flat design also gives them a more uniform soundstage than headphones with coiled dynamic drivers. In addition they are less susceptible to leakage that is the sound that escapes the headphone cups and enters the surrounding environment. In some instances this can be a problem because it can distract listeners and alter their focus when listening to music. In other instances, however, it can be beneficial as it allows listeners to enjoy music in public environments without having to worry about disturbing others close by.

Instead of putting the coil that is behind a diaphragm that is shaped like cones, planar magnetic headsets have an array of printed patterns on a thin layer of the actual diaphragm. This conductor is then suspended in between two magnets and when an electrical signal is applied to the array, it turns into electromagnetic which causes the magnetic forces on either side of the diaphragms to interact with each with each other. This is the reason why the diaphragm begins to vibrate, which creates the sound wave.

The smooth movement of the lightweight diaphragm and the fact that the force is evenly distributed across its surface which means distortion is incredibly low. This is an enormous 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, most HiFi audiophiles are now adopting this old technology to create new generation planar magnetic headphones that sound incredible. Some of these models are extremely expensive and require a premium amplifier to run them however, for those who can afford them, they provide an incredible experience that is unmatched by any other headphone. They deliver a deep and clear sound without the distortion you get with other headphones.

Minimal Inertia

Due to their design, planar diaphragms can move faster and are lighter than conventional drivers. They can reproduce audio signals with greater precision and can be tuned to a wider range. They also give an authentic sound and have less distortion than traditional dynamic speakers.

The two rows of a planar driver generate equal and uniform magnetic force across the entire diaphragm surface. This will eliminate any unnecessary and unwanted distortion. Since the force exerted on the diaphragm's light weight is evenly distributed it is able to be controlled more precisely. This allows the diaphragm vibrate in a perfectly pistonic motion, resulting in an accurate and smooth music reproduction.

They are also capable of achieving extremely high levels of performance while carrying very little weight. This makes them ideal for headphones that can be carried around. They can also be designed to produce a range in frequencies, ranging from low frequency sounds to high-frequency ones. Audio professionals appreciate them for visit the next internet site their broad frequency response and precise sound.

Unlike dynamic drivers, which use coils to push against the diaphragm, planar magnetic drivers have no mechanical parts that can meet with each other and cause distortion. This is due to the fact that the flat array is placed directly on top of the diaphragm rather than being in the form of a coil that is behind.

A planar magnetic driver in contrast, can drive a small and light diaphragm by applying a tremendous magnetic force with no loss of energy. This means that the diaphragm can be driven with an even pressure, preventing it from deforming and causing distortion.

The moment of inertia describes the resistance to rotation of an object. It can be calculated using the formula I = mr2. The shape of the object determines its minimum moment of inertia. Longer and thinner objects have lower moments of inertia.
