5 Tools That Everyone Working In The Planar Magnetic Industry Should Be Utilizing
How a Planar Magnetic Diaphragm Headphone Driver Works

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

However, the force that is exerted is limited to a narrow area, and it's hard for various points on the diaphragms to move at the same at the same time. This can lead to distortions caused by breakup modes.

Sound Detail

Many audiophiles are looking to get an authentic sound from their headphones. A good way to achieve this is through a planar magnetic diaphragm. This type of headphone driver functions similarly to cone drivers with dynamic characteristics however with more modern technology behind it.

A planar diaphragm has an elongated structure that is built into the headphone's frame and made out of a lightweight, thin film-like material. It's made to be as uniform as is possible, and its flat surface allows an even distribution of pressure across the entire surface which, in turn, improves the clarity of sound.

The flat design allows for a better soundstage. A more focused soundstage can be achieved by a more focused wavefront. This helps determine 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.

In contrast to traditional dynamic drivers, which utilize a voice coil placed to the center of a paper or plastic cone, a planar diaphragm makes use of magnets placed on both sides of its flat face. The electrical current passing through the voice coil interacts with the magnets, causing the diaphragm to vibrate and produce sound. The entire diaphragm is driven simultaneously. This is a way to eliminate breakup modes, mechanical filters, transmission delays and local resonances that could have a negative impact on sound quality.

A diaphragm that is flat and uniform can also accelerate faster than a thicker, heavier one used in dynamic drivers. Physics' laws of physics say that force is proportional to acceleration and mass, so the faster a diaphragm can move the more force it exerts. This gives planar magnetic drivers a more precise bass response and superior detail retrieval.

Of course, the advantages of the planar magnetic driver do not come without a price. Because they have a complicated motor system and a large diaphragms, they generally cost more than dynamic drivers, are heavier and require a stronger amplifier to work properly. Many planar magnetic headphone makers can take advantage of their technology and create high-performance headphones for competitive prices. Some 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 use a flat membrane instead of the traditional dome or cone shaped membrane. As an electrical signal passes through it, it interacts with magnets on both sides of the diaphragm. It produces sound waves by vibrating the diaphragm. The diaphragm that is flat is able to react quickly to sound and produce a broad range of frequencies ranging from lows to highs.

Get Source of a planar magnetic design is that it's more sensitive than other types of headphone drivers, which utilizes a diaphragm that is that is up to a few times larger in volume than a typical planar headphone. This creates an incredible amount of dynamic range and clarity which allows you to appreciate every detail your music has to provide.

In addition, planar magnetic drivers produce an extremely uniform driving force throughout the diaphragm that eliminates breakup points and produces an uncluttered sound that is free of distortion. This is especially important for high-frequency sounds, where the sound can be distorted and distracting. In the FT5 this is accomplished through the use of a sophisticated material called polyimide, which is extremely light and robust, as well as a sophisticated conductor pattern that eliminates the inductance related intermodulation distortion.

OPPO's planar magnetic drivers also have much better coherence in phase, which means that when a wavefront enters the ear canal, it is a perfectly flat and unaltered shape. Dynamic drivers, on the other hand are spherical in their wavefront that disrupts this coherence and causes low-quality signal peak reconstructions of the signal, especially in high frequencies. OPPO headphones sound very natural and realistic.

Wide Frequency Response

Planar magnetic diaphragms have the ability to reproduce sounds at higher frequencies than traditional drivers. This is because their thin and lightweight diaphragm is very precise in its movement. This enables them to deliver an excellent transient response. This makes them a great choice for audiophiles who require quick responses from their speakers and headphones to reproduce the finest details in music.

This flat structure also allows them to have a more even soundstage than regular headphones with dynamic drivers that are coiled. Additionally they are less prone to leakage, which is the sound that escapes from headphone cups and enters the surrounding environment. In certain situations, this could be a problem, as it can distract the listener, and make them lose focus while listening to music. In some cases, this can be a problem because it can cause listeners to lose focus and distract their concentration when listening to music.

Instead of using a coil behind a diaphragm shaped as a cone the planar magnetic headsets feature an array printed on a thin film of the actual diaphragm. This conductor is then suspended in between two magnets and when an electrical signal is applied to this array, it turns into electromagnetic and causes the magnetic forces that are on either side of the diaphragm to interact with each one. This is the reason why the diaphragm begins to vibrate, resulting in a sound wave.

The uniform motion of the diaphragm that is light and the fact that force is evenly distributed across its surface this means that distortion is extremely low. This is a significant improvement over traditional dynamic drivers which are known for producing distortion at very high levels of listening.

Some high-end headphones use the old-school moving coil design. However, the majority of HiFi audiophiles are now embracing this long-forgotten technology to create new generation of planar magnetic headphones that sound amazing. Some of these headphones are extremely expensive and require a top-of-the-line amplifier to power them however, for those who can afford them they offer an exceptional experience that is unlike any other headphone. They offer a full and detailed sound without the distortion that is common with other headphones.

Minimal Inertia

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

The dual rows of magnets inside a planar driver produce equal and uniform magnetic forces across the entire surface of the diaphragm. This prevents unwanted and unnecessary distortion. Because the force on the diaphragm's lightweight is evenly distributed, it can be controlled more precisely. This allows the diaphragm be able to move in a precise pistonic motion, leading to an accurate and smooth music reproduction.


They are also capable of achieving very high levels of performance with minimal weight. This makes them ideal for use as a portable headphone. They can also be made to produce a wide range in frequencies, from low-frequency sounds to high-frequency ones. The high frequency response and the precise sound reproduction make them a favourite for audio professionals.

Planar magnetic drivers are different from dynamic drivers that 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 flat array is placed directly on top of the diaphragm instead of in a coil behind.

In contrast the light and thin diaphragm in a planar driver can be driven by a powerful magnetic field without any loss of energy. As a result, the diaphragm is driven with an even pressure, preventing it from deforming and producing distortion.

The moment of inertia defines the resistance to rotation of an object. It can be 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.
