How a Planar Magnetic Diaphragm Headphone Driver Works
Traditionally, dynamic drivers have a voice coil attached to the middle of a conical diaphragm. When electrical signal passes through the voice coil, it causes the diaphragm to move.
The force is applied to a small portion of the diaphragm, so it's difficult to move several points simultaneously. This causes breakup modes that can cause distortion.
Audio with a Detailed Sound
Many audiophiles want an accurate sound from their headphones. One method to achieve this is with a planar magnetic diaphragm. This type of headphone operates in a similar manner to dynamic cone drivers but with much more advanced technology.
A planar diaphragm is flat structures that are integrated into the headphone's frame. It's made from a thin, lightweight film-like material. It's designed to be as flat and uniform as possible. This allows for an even distribution of pressure across the entire surface.
The flat design of a planar diaphragm magnetic diaphragm allows for a more controlled soundstage. A more precise wavefront results in better sound staging that can help identify the exact location of an instrument or vocal on the track. This is a major advantage over the more spherical wavefront typical of dynamic drivers.
In contrast to traditional dynamic drivers, which make use of a voice coil placed close to the center of a paper or plastic cone, a planar diaphragm utilizes magnets placed on each side of its flat face. The diaphragm vibrates and produces sound when the electrical current that passes through the voice coil interacts with these magnets. Because the entire diaphragm is driven simultaneously there is no breakup modes, mechanical filtering, transmission delay or local resonances that could negatively affect 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. The laws of physics state that force is proportional to acceleration and mass, so the faster a diaphragm is able to move the more power it will exert. This gives planar magnetic drivers a more accurate bass response and greater detail retrieval.
Of course, the advantages of a planar magnetic driver don't come without a price. They're more expensive than dynamic drivers because they have a large diaphragm as well as a complex motor. They also require a stronger amplifier to function properly. However, many manufacturers of planar magnetic headphones are able to make the most of their technology to create high-quality headphones at a reasonable price. Audeze LCD-4, HiFiMAN Susvara are just a few examples.
High Sensitivity
The planar driver is different from the moving coil drivers found in the majority of headphones and IEMs in that it uses a flat diaphragm instead of a dome or cone-shaped membrane. When an electrical signal travels through, it interacts both with the magnets and the diaphragm, generating sound waves. The flat nature of the diaphragm enables it to react very quickly to sound and generate an array of frequencies, from bass to highs.
Planar magnetic headphones are more sensitive than other headphone drivers that utilize diaphragms that are several time larger than the typical planar design. This lets you listen to all the details of your music.
In addition the planar magnetic drivers provide an extremely uniform driving force across the entire diaphragm, which eliminates breakup points, and provides a smooth sound that's free of distortion. This is particularly important for high-frequency sounds, where breakups can be noticeable and distracting. In the FT5, this is achieved by utilizing a highly advanced material called polyimide. It is extremely light and robust, as well as a specialized conductor pattern that blocks inductance related intermodulation distortion.
OPPO's planar magnetic drivers have better phase coherence. This means that when an audio wavefront strikes our ear, it's flat and unaltered. Dynamic drivers have a spherical wavefront, which disrupts the coherence of the signal, which results in less-than-perfect reconstructions of the highest frequencies, particularly at high frequencies. This is another reason that the OPPO headphones sound so real and natural, and incredibly accurate.
Wide Frequency Response
A planar magnetic diaphragm has the ability to reproduce sounds with much greater frequency than conventional dynamic drivers, thanks to their diaphragms are thin and lightweight. moves in a very controlled way. They can provide an outstanding transient response. This makes them an ideal option for audiophiles who are looking for speakers and headphones that reproduce the finest details of music.
This flat design provides a more even soundstage than headphones that utilize a dynamic driver coiled. Additionally, they are less prone to leakage which is the sound that escapes the headphones and out into the surrounding area. In some instances, this can be a problem as it can distract the listener and make them lose focus while listening to music. In some instances this could be a problem because it can cause listeners to lose focus and distract their focus when listening to music.
Instead of using the coil that is behind a diaphragm that's shaped like a cone, planar magnetic headsets have an array of printed patterns on a thin film of the diaphragm. The conductor is hung between two magnets. When an electrical signal is applied, it becomes electromagnetic and causes the magnetic forces that are on either side of the diaphragm to interact with each other. This is what causes the diaphragm to vibrate, creating a soundwave.
The low distortion is due to the uniform motion of the lightweight, thin diaphragm and the fact that force is evenly dispersed across its surface. This is an improvement over traditional dynamic drivers which are known to cause distortion at high levels of listening.
Some premium headphones still employ the old-fashioned moving coil design, however most HiFi audio enthusiasts are now embracing a long-forgotten technology and a new generation of amazing sounding planar magnetic headphones. Some of these headphones are extremely expensive and require a high-end amplifier to power them however, for those who can afford them they offer an amazing experience that's unrivalled by any other headphone. They offer a full and clear sound without the distortion that is common with other types of headphones.
Minimal Inertia
Due to their construction the diaphragms of planar diaphragms move faster and are lighter than conventional drivers. They reproduce audio signals with greater precision and can be tuned to a wider range. They also provide a more natural sound and have less distortion than traditional dynamic speakers.
The two rows of magnets inside a planar driver produce equal and uniform magnetic forces across the entire diaphragm's surface. This will eliminate any unnecessary and unwanted distortion. The diaphragm that is lightweight can be controlled better because the force is evenly dispersed. This permits the diaphragm to move with a precise pistonic movement.
They also have the capability of achieving extremely high levels in performance with the smallest weight. This makes them perfect for portable headphone. Additionally, linked site can be produced to have a wide range of frequencies, ranging from deep bass to high-frequency sounds. The wide frequency response and accurate sound reproduction make them a favourite for audio professionals.
Contrary to dynamic drivers that utilize coils to push against the diaphragm and vice versa, planar magnetic drivers have no mechanical parts that can come into contact with each with each other, causing distortion. This is due to the fact that the conductors' flat array rests directly on the diaphragm rather than being enclosed in a coil behind.
In contrast the slim and light diaphragm in a planar magnetic driver can be driven by an extremely strong magnetic field without loss of energy. In the end, the diaphragm is driven by an even pressure, which prevents it from bending and causing distortion.
The moment of inertia is the resistance to rotation of an object. It is calculated using the formula I = mr2. An object's shape affects its minimum moment of inertia with longer and thinner objects having lower moments of inertia than larger and thicker objects.
