How a Planar Magnetic Diaphragm Headphone Driver Works

Traditionally, dynamic drivers have a voice coil attached to the middle of the conical diaphragm. When electrical signals pass through the voice coil it causes the diaphragm to move.

The force is applied to a tiny portion of the diaphragm, so it’s difficult to move several points simultaneously. This can lead to breakup patterns which can cause distortion.

Sound Detail

Many audiophiles would like to hear clear and precise sound through their headphones. This is possible with the planar diaphragm. This type of headphone works in a similar manner to dynamic cone drivers, but with a much more advanced technology.

A planar headphone diaphragm is an elongated structure that is embedded in the headphone’s frame. It’s constructed of a light, thin film-like material. It’s designed to be as uniform and flat as it is possible. This ensures an even pressure distribution across the entire surface.

The flat shape of a planar magnetic diaphragm creates a more controlled soundstage. A more focused soundstage is achieved by a more focused wavefront. This can help you identify where an instrument or vocal is located on the track. This is an important benefit over the more spherical wavefront typical of dynamic drivers.

Contrary to traditional dynamic drivers which utilize a voice coil attached close to the center of a paper or Planar Magnetic plastic cone, a planar diaphragm utilizes magnets that are placed on each side of its flat surface. The electrical current flowing through the voice coil interacts with these magnets to drive the diaphragm and produce sound. The entire diaphragm can be driven at the same time. This eliminates breakup modes, mechanical filters, transmission delays, and local resonances that could have a negative impact on the quality of sound.

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

Of course, the advantages of a planar magnetic driver don’t come without cost. Since they come with a complex motor system and a large diaphragm, they typically cost more than dynamic drivers, are bulkier and require a higher-powered amplifier to perform properly. However, a lot of manufacturer of planar magnetic headphones can make the most of their technology to produce high-quality headphones at a reasonable price. Audeze LCD-4, HiFiMAN Susvara are just a few examples.

High Sensitivity

The planar driver differs from moving coil drivers, found in the majority of headphones and IEMs, in that it utilizes a flat diaphragm instead of a cone or dome shaped membrane. As an electrical signal moves through, it interacts both with the magnets as well as the diaphragm to produce sound waves. The flat nature of the diaphragm permits it to react quickly to sound and can produce a wide range of 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 allows you to be able to hear every detail in your music.

Planar magnetic drivers also provide an extremely consistent driving force that is evenly distributed throughout the diaphragm. This prevents breakup and creates a smooth, distortion-free sound. This is particularly crucial for high frequencies, where the presence of breakup can be very audible and distracting. In the FT5, this is achieved by utilizing a highly advanced material called polyimide. It is extremely light and strong, and a sophisticated conductor pattern that blocks inductance associated intermodulation distortion.

The planar magnet drivers of OPPO have better phase coherence. This means that when the sound wavefront hits our ear, it’s flat and unaltered. Dynamic drivers, on the other hand, have a spherical wavefront, which disrupts this coherence and leads to less-than-perfect signal peak reconstructions particularly at high frequencies. This is another reason for why OPPO’s headphones sound so realistic and natural, and extremely accurate.

Wide Frequency Response

Planar magnetic diaphragms are able to reproduce sounds at much higher frequencies than traditional drivers. This is because their diaphragms are thin and light. moves very precisely. They can deliver an outstanding transient response. This makes them a perfect choice for audiophiles looking for headphones and speakers that reproduce the most precise details of music.

This flat structure also allows them to have a more even soundstage than headphones that use dynamic drivers that are coiled. They are also less prone to leakage – sound that escapes from the headphones into the environment. In certain situations this is a concern because it can distract listeners and disrupt their focus when listening to music. In other instances however, it can be beneficial since it lets listeners enjoy music in public environments without worrying about disturbing other people close by.

Rather than using a coil that is placed behind a cone-shaped diaphragm, planar magnetic headphones have conductors arranged on the thin diaphragm. This conductor is then suspended in between two magnets and when an electrical signal is applied to this array it becomes electromagnetic and causes the magnetic planar speakers forces on the opposite side of the diaphragm to interact each other. This is the reason why the diaphragm begins to vibrate, creating an audio wave.

The low distortion is due to the uniform motion of the lightweight, thin diaphragm, and the fact that force is evenly distributed across its surface. This is an enormous improvement over traditional dynamic drivers, that are known for causing distortion at 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 a new generation planar magnetic headphones that sound amazing. Some of these headphones are extremely expensive and require a premium amplifier to provide power however, for those with the money they offer an amazing experience that’s unrivalled by any other headphone. They have a deep clear, clear sound that’s free from the distortion inherent in other headphone models.

Minimal Inertia

As a result of their design they are extremely light and move much more quickly than traditional drivers. This means they can reproduce audio signals with greater precision and can be tuned to more frequencies. They also give a more natural sound and have less distortion than traditional dynamic speakers.

The two rows of a planar driver generate equal and uniform magnetic force across the diaphragm’s surface. This will eliminate any unnecessary and unwanted distortion. Since the force exerted on the diaphragm’s lightweight is distributed evenly and evenly, it can be controlled more precisely. 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 minimal weight. This makes them ideal for portable headphone. They can also be made to provide a wide range of frequencies, ranging from deep bass to high-frequency sounds. The high frequency response and the precise sound reproduction make them a popular choice for audio professionals.

closed-Back planar magnetic Headphones magnetic drivers are different from dynamic drivers which use coils to push the diaphragm. They don’t have any mechanical parts which can cause distortion. This is because the flat array sits directly on the diaphragm’s top, rather than in a coil behind.

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

The moment of inertia is the resistance to rotation of an object. The formula I = mr2 can be used to calculate it. The shape of an object affects its minimum moment of inertia with objects that are thinner and larger having lower moments of inertia than larger and thicker ones.
