How a Planar Magnetic Diaphragm Headphone Driver Works

Typically, dynamic drivers comprise a voice coil attached to the middle of the conical diaphragm. When electrical signals pass through a voice coil, the diaphragm is moved.

However, the force that is exerted is limited to a tiny area, making it difficult for different points on the diaphragm to move at same time. This can lead to distortions due to breakup patterns.

Sound Detail

Many audiophiles want to hear clear and precise sound through their headphones. A good method to achieve this is through a planar magnetic closed back headphones magnetic diaphragm. This kind of headphone driver operates similarly to cone drivers that are dynamic however with more modern technology behind it.

A planar earphones diaphragm is a flat structure embedded in the frame of a headphone and is made of a fine and lightweight material. It is designed to be as uniform and flat as is possible. This enables an even pressure distribution across the entire surface.

A planar magnetic diaphragm's flat design allows for a better soundstage. A more precise wavefront leads to better sound staging that can help pinpoint the location of a instrument or vocal on the track. This is an important advantage over the more spherical wavefront typically of dynamic drivers.

Contrary to traditional dynamic drivers which make use of a voice coil placed to the center of a paper or plastic cone, a planar diaphragm makes use of a series of magnets on each side of its flat surface. The electrical current flowing through the voice coil interacts with the magnets to drive the diaphragm, which causes it to vibrate and create sound. Because the entire diaphragm is driven at once there is no breakup modes mechanical filtering, transmission delay or local resonances which could adversely affect sound quality.

A diaphragm that is flat and uniform is also capable of accelerating more quickly than the larger and more heavy ones used in dynamic drivers. According to the laws of physics force is proportional to mass and acceleration. This means that the faster a driver's diaphragm moves, the more power they are able to exert. This gives planar magnetic drivers better response to bass and superior planar Earphones detail retrieval.

Of course, the advantages of a planar magnetic driver don't come without cost. They're more expensive than dynamic drivers since they have a large diaphragm and a complex motor. They also require a stronger amplifier to function effectively. However, a lot of manufacturer of planar magnetic headphones are able to make the most of their technology to make premium headphones that are priced competitively. Some examples include the Audeze LCD-4 and HiFiMAN Susvara.

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 in place of a cone or dome shaped membrane. When an electrical signal travels through it, it interacts with the magnets as well as the diaphragm to produce sound waves. The flat nature of the diaphragm enables it to react very quickly to sound and generate many different frequencies, ranging from bass to highs.

Planar magnetic headphones are more sensitive than other headphone drivers which make use of diaphragms several time larger than a standard planar design. This lets you listen to all the details of your music.

Planar magnetic drivers also produce an extremely constant driving force throughout the diaphragm. This eliminates breakup and produces an undistorted, smooth sound. This is especially important for high-frequency sounds, where the presence of breakups can be quite loud and distracting. This is achieved in the FT5 by utilizing polyimide, a material that is both ultralight and durable, and a sophisticated design of conductors that eliminates distortion in 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's flat and unaltered. Dynamic drivers however are spherical in their wavefront that disturbs the coherence, resulting in low-quality signal peak reconstructions of the signal, especially in high frequencies. OPPO headphones sound incredibly real and natural.

Wide Frequency Response

Planar magnetic diaphragms are able to reproduce sounds at higher frequencies than traditional dynamic drivers. This is because their diaphragms are thin and light. moves extremely precisely. This allows them to provide high-quality transient response, which makes them an exceptional option for audiophiles who need rapid response from their headphones and speakers to reproduce the finest details in music.

This flat design also gives them a more even soundstage than headphones that have coiled dynamic drivers. In addition, they are less prone to leakage, which is the sound that escapes the headphones and out into the environment around you. In some cases this is a concern because it can distract listeners and alter their focus when listening to music. In other situations, it can be beneficial as it allows listeners to enjoy their music in public areas without having to worry about disturbing others near by.

Rather than using a coil behind a cone-shaped diaphragm planar headphones are made up of conductors arranged on the very thin film of the diaphragm itself. The conductor is then suspended in between two magnets, and when an electrical signal is applied to this array, it transforms into electromagnetic and causes the magnetic forces on the opposite side of the diaphragm to interact with each other. This is what is a planar headphone makes the diaphragm vibrate and create a soundwave.

The uniform movement of the diaphragm, which is lightweight and the fact that the force is evenly distributed across its surface, Planar Earphones means that distortion is incredibly low. This is a significant improvement over traditional dynamic drivers which are known for producing distortion at high levels of listening.

Certain high-end headphones employ the old-fashioned moving coil design. However, most HiFi audiophiles are embracing this long-forgotten technology to create new generation of planar magnetic headphones that sound incredible. Certain models require a premium amp to drive them. For those who are able to afford it, they offer an experience that is unlike any other headphones. They have a deep and detailed sound that is free from the distortion inherent in other headphone types.

Minimal Inertia

Due to their design they can move faster and are lighter than traditional drivers. They reproduce audio signals with greater accuracy and can be tuned to a wider range. They also provide more natural sound and have less distortion than traditional dynamic speakers.

The two rows of a planar magnet driver produce equal and uniform magnetic force across the entire diaphragm surface. This will eliminate any unnecessary and unwanted distortion. The lightweight diaphragm is more manageable since the force is evenly distributed. This permits the diaphragm to move in a precise pistonic motion, which results in smooth and accurate music reproduction.

They also have the capability of achieving high levels in performance with minimal weight. This makes them ideal for portable headphone. They can also be designed to provide a variety in frequencies, from low-frequency sounds to high-frequency ones. The wide frequency response and accurate sound reproduction make them a popular choice for audio professionals.

Contrary to dynamic drivers that use coils to push against the diaphragm the planar magnetic driver has no mechanical components that could come into contact with each the other and cause distortion. This is due to the fact that the flat array of conductors is placed directly on the diaphragm, instead of in a coil behind it.

In contrast the slim and light diaphragm of a planar magnetic driver can be driven by a strong magnetic field without loss of energy. The diaphragm, a thin, lightweight membrane, is driven by the magnetic field, which exerts an unchanging pressure. This prevents it from deforming or creating distortion.

The moment of inertia is an important property that describes the resistance of an object to rotation. The formula I = mr2 may be used to determine it. The shape of an object affects its minimum moment of inertia. Thicker and longer objects have lower moments of inertia.
