How a Planar Magnetic Diaphragm Headphone Driver Works

In the past, dynamic drivers had a voice coil attached at the center of the dialephragm, which is conical. When an electrical signal passes through a voice coil, the diaphragm shifts.

However, the force applied is limited to a tiny area and it's difficult to allow different parts of the diaphragms to move at the same at the same time. This can lead to distortions caused by breakup patterns.

Sound Detail

Many audiophiles are looking to get a detailed sound from their headphones. A good way to achieve this is with a planar magnetic diaphragm. This type of headphone works in a similar way to dynamic cone drivers, but with more modern technology.

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

A planar magnetic diaphragm's flat design provides a greater soundstage. A more precise wavefront leads to better sound staging, which can help you pinpoint the location of a vocal or instrument on the track. This is a major advantage over the more spherical waves typically of dynamic drivers.

A planar diaphragm is distinct from the traditional dynamic drivers that utilize a voice coil that is attached to the center of a cone made of paper or plastic. Instead, it uses a series of magnets on each side of its flat surface. The diaphragm vibrates and produces sound when the electrical current that passes through the voice coil interacts with the magnets. The entire diaphragm can be controlled simultaneously. This removes breakup modes mechanical filters, transmission delays and local resonances that can have a negative impact on sound quality.

A diaphragm that is flat and uniform can also accelerate faster than a more substantial, thicker one 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 results in planar magnetic drivers more accurate bass response and superior detail retrieval.

The advantages of a planar magnetic driver are not without cost. They're more expensive than dynamic drivers because they have a large diaphragm as well as a complex motor. They also require a more powerful amplifier to work efficiently. Many manufacturers of planar earphone magnetic headphones are able to take advantage of their technology and create premium headphones at competitive prices. 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 employ a flat membrane instead of a traditional dome or cone shaped membrane. When an electrical signal travels through it, it interacts with magnets on both sides of the diaphragm. This produces sound waves by bouncing the diaphragm. The diaphragm that is flat is able to respond quickly to sound, and can produce a wide range in frequencies from lows to highs.

planar driver magnetic headphones are more sensitive than other headphone drivers, which can utilize diaphragms that are multiple times larger than a standard planar design. This lets you listen to all the details of your music.

In addition that, planar magnetic drivers create an extremely uniform driving force throughout the diaphragm, which eliminates breakup points and produces a smooth sound that's free of distortion. This is particularly crucial for high frequencies where the sound's breakup can be very audible and distracting. In the FT5 this is accomplished by using an advanced material called polyimide. It is both ultra-light and extremely strong, and a sophisticated conductor pattern that blocks inductance related intermodulation distortion.

OPPO's planar magnetic drivers offer a superior phase coherence. This means that when a sound wavefront hits our ear, it's flat and unaltered. Dynamic drivers, on the other hand, have a spherical wavefront that disrupts the coherence, resulting in poor signal peak reconstructions, especially in high frequencies. This is another reason why the OPPO headphones sound so authentic and natural, and extremely accurate.

Wide Frequency Response

A planar magnetic diaphragm is able to reproduce sounds at greater frequency than conventional dynamic drivers due to their diaphragm is thin and light in weight. is moved in a controlled manner. They can provide an excellent transient response. This makes them a great choice for audiophiles looking for headphones and speakers that reproduce the finest details of music.

The flat design gives them a more even soundstage than traditional headphones that employ a dynamic driver that is coiled. They are also less prone to leakage - sound that leaks out of the headphones and into the environment. In some cases this can be a problem, as it can distract the listener, What are planar magnetic Drivers and make them lose focus when listening to music. In certain situations, this can be a problem since it can distract listeners and alter their focus while listening to music.

Instead of putting a coil 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 suspended between two magnets. When an electrical signal is applied to it, the conductor becomes electromagnetic, and the magnetic forces on the opposite side of the diaphragm interact with each other. This is What are planar magnetic drivers causes the diaphragm vibrate, resulting in an audio wave.

The low distortion is due to the uniform movement of the light, thin diaphragm as well as the fact that the force is evenly dispersed across its surface. This is a significant improvement over traditional dynamic drivers that have been known to cause distortion at very high levels of listening.

Some high-end headphones still use the old-fashioned moving coil design, however most HiFi audio enthusiasts are now using a technology that was long forgotten and a new generation of amazing sounding planar magnetic headphones. Some of these models are extremely expensive and require a top-of-the-line amplifier to provide power however, for those with the money they offer an amazing experience that is unlike any other headphone. They have a deep and detailed sound that is free from the distortion inherent in other types of headphone.

Minimal Inertia

As a result of their construction the planar magnetic diaphragms are extremely light and can move faster than conventional drivers. They can reproduce audio signals with greater accuracy and can be tuned to a wider range. They also produce an authentic sound and have less distortion than traditional dynamic speakers.

The two rows of a planar magnet driver produce the same and uniform force across the diaphragm's surface. This removes any unwanted and unnecessary distortion. The lightweight diaphragm can be more easily controlled since the force is evenly distributed. This allows the diaphragm vibrate in a perfectly pistonic motion, leading to smooth and accurate music reproduction.

Planar magnetic drivers are capable of achieving extremely high levels of performance at very little weight, which makes them ideal for use with portable headphones. They are also able to produce a range in frequencies, ranging from low-frequency sounds to high-frequency ones. Audio professionals love them due to their wide frequency response and clear sound.

Contrary to dynamic drivers that use coils to push against the diaphragm the planar magnetic driver has no mechanical parts that can meet with each other and cause distortion. This is because the flat array is placed directly on the diaphragm's top rather than being in a coil behind.

A planar magnetic driver on the other hand can drive a light and thin diaphragm with an extremely powerful magnetic force without any loss of energy. The diaphragm is an extremely thin and lightweight membrane is driven by the magnetic field, which exerts a constant pressure. This prevents it from bending or causing distortion.

The moment of inertia defines the resistance to rotation of an object. The formula I = mr2 may be used to determine it. The shape of the object influences its minimum moment of inertia with longer and thinner objects have lower moments of inertia compared to bigger and more robust ones.
