How a Planar Magnetic Diaphragm Headphone Driver Works
Typically, dynamic drivers feature an internal voice coil that is attached to the center of a conical diaphragm. When electrical signals pass through the voice coil, it causes the diaphragm to move.
However, the force applied is limited to a narrow area and it's difficult to allow different parts of the diaphragm to move at same at the same time. This can cause distortions caused by breakup modes.
Sound Detail
Many audiophiles want clear and precise sound through their headphones. A good method to achieve this is with a planar magnetic diaphragm. This type of headphone driver operates in a similar fashion as dynamic cone drivers however, with more advanced technology behind it.
A planar diaphragm is an elongated structure that is embedded within the headphone's frame and is made of a fine, lightweight material. It is designed to be as flat and uniform as it is possible. This enables an even pressure distribution across the entire surface.
The flat shape of a planar magnetic diaphragm also creates a more controlled soundstage. A more focused wavefront results in better sound staging that can help identify the exact location of an vocal or instrument on the track. This is a major advantage over the more spherical waves typical of dynamic drivers.
A planar diaphragm is different from traditional dynamic drivers which utilize a voice coil that is attached to the center of a cone made of paper or plastic. Instead, it uses a series magnets on either side of its flat surface. The diaphragm vibrates and creates sound when the current that passes through the voice coil interacts with the magnets. Because the entire diaphragm is driven at the same time, there are no breakup modes mechanical filtering transmission delay, or local resonances that can negatively affect the quality of sound.
A diaphragm that is flat and uniform can also accelerate more quickly than a more substantial, thicker one used in dynamic drivers. Physics' laws of physics say that force is proportional to mass and acceleration so the faster a diaphragm can move the more power it can exert. This gives planar magnetic drivers more precise bass response and better detail retrieval.

The advantages of a planar magnet driver are not without cost. Because they feature a complex motor system and a large diaphragm, they usually cost more than dynamic drivers, are bulkier and require a stronger amplifier to work properly. Many manufacturers of planar magnetic headphones benefit from their technology and design 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, it interacts both with the magnets as well as the diaphragm, generating sound waves. The diaphragm that is flat is able to respond quickly to sound, and it can produce a wide spectrum of frequencies from lows to highs.
Planar magnetic headphones are more sensitive than other drivers for headphone that utilize diaphragms that are several time larger than a standard planar design. This allows you to be able to hear every detail in your music.
Planar magnetic drivers also create a very consistent driving force that is evenly distributed throughout the diaphragm. This eliminates breakup and creates a smooth, distortion-free sound. This is especially important for high-frequency sounds in which the presence of breakups can be extremely audible and distracting. In the FT5 the way this is achieved is by using an advanced material called polyimide, which is extremely light and robust, as well as a sophisticated conductor pattern that eliminates inductance related intermodulation distortion.
The OPPO's planar magnetic driver also have a higher degree of coherence in phase, which means that when a wavefront hits our ear canal, it's an unaltered, flat shape. Dynamic drivers however they have a spherical-shaped wavefront that disturbs this coherence and leads to poor signal peak reconstructions particularly at high frequencies. This is another reason for why OPPO's headphones sound so realistic and natural, as well as extremely precise.
Wide Frequency Response
Planar magnetic diaphragms have the ability to reproduce sounds at higher frequencies than traditional dynamic drivers. This is because their diaphragm is thin and light in weight. moves extremely precisely. This allows them to provide high-quality transient response, which makes them an exceptional option for audiophiles who need rapid responses from their headphones and speakers to reproduce the finest details in music.
This flat design also provides them with a more uniform soundstage than regular headphones that have coiled dynamic drivers. They are also less prone to leakage, which is the sound that leaks out of the headphones into the environment. In some cases this is a concern because it can distract listeners and alter their concentration when listening to music. In other cases however, it can be beneficial because it allows listeners to enjoy their music in public areas without having to worry about disturbing others near by.
Instead of putting a coil behind a diaphragm shaped as a cone, planar magnetic headsets have an array printed on a thin layer of the diaphragm. This conductor is then suspended in between two magnets and when an electrical signal is applied to the array, it turns into electromagnetic, causing the magnetic forces that are on either side of the diaphragm to interact with each other. This is what makes the diaphragm vibrate, creating the sound wave.
The low distortion is due to the consistent movement of the thin, lightweight diaphragm and the fact that the force is evenly dispersed across its surface. This is an enormous improvement over traditional dynamic drivers, which are known for producing distortion at high levels of listening.
Some high-end headphones still use the old-fashioned moving coil design, but most HiFi audio enthusiasts are now adopting a long-forgotten technology and a new generation of incredible sounding planar magnetic headphones. Some of these models require a top-of-the-line amplifier to power them. However, for those who can afford it, they provide an experience that is unmatched by any other headphone. They offer a rich, detailed sound that is free of the distortion that is common in other headphone models.
Minimal Inertia
Because of their design the planar magnetic diaphragms are extremely light and can move much faster than conventional drivers. This means they can reproduce audio signals more precisely and can be tuned to more frequencies. They also produce an authentic sound with less distortion than traditional loudspeakers.
The dual rows in a planar magnet driver create equal and uniform magnetic force across the diaphragm's surface. This eliminates unwanted and unnecessary distortion. The lightweight diaphragm can be controlled better because the force is evenly dispersed. This allows the diaphragm move in a precise pistonic motion, which results in an accurate and smooth music reproduction.
Planar magnetic drivers are also capable of achieving extremely high levels of performance with a minimal weight, making them ideal for portable headphones. They can also be produced to have a wide range of frequencies, ranging from deep bass to high-frequency sounds. Audio professionals appreciate them for their broad frequency response and accurate sound.
Planar magnetic drivers differ from dynamic drivers that utilize coils to push the diaphragm. They don't have any mechanical components that could cause distortion. This is due to the fact that the flat array of conductors rests directly on the diaphragm instead of within a coil behind it.
In contrast the slim and light diaphragm inside a planar driver can be driven by an extremely powerful magnetic field with no loss of energy. This means that the diaphragm is driven by an even pressure, which prevents it from deforming and causing distortion.
The moment of inertia is the resistance to rotation of an object. The formula I = mr2 could be used to calculate it. The shape of an object influences its minimum moment of inertia. Longer and smaller objects have lower moments of inertia.
