How a Planar Magnetic Diaphragm Headphone Driver Works
In the past, dynamic drivers featured an attached voice coil at the center of a conical dialephragm. When click through the following article pass through a voice coil, the diaphragm is moved.
However, the force exerted is limited to a tiny area and it's difficult for various points on the diaphragms to move at the same time. This causes breakup modes that can cause distortion.
Audio with a Detailed Sound
Many audiophiles want clear and precise sound through their headphones. This is possible through the planar diaphragm. This type of headphone driver functions in a similar way to cone drivers with dynamic characteristics however with more advanced technology behind it.
A planar diaphragm is an elongated structure embedded in the headphone's frame and is made of a fine light material. It is designed to be as uniform and flat as it is possible. This enables an even distribution of pressure across the entire surface.
The flat design creates a more spacious soundstage. A more focused soundstage can be created by a more precise wavefront. This helps pinpoint the exact location where a vocal or instrument is on the track. This is an advantage over the more spherical waves typical of dynamic drivers.
A planar diaphragm is distinct from traditional dynamic drivers which use a voice-coil attached to the cone's central point composed of plastic or paper. Instead, it utilizes a series magnets on either side of its flat surface. The diaphragm is vibrating and emits sound when the current that passes through the voice coil is absorbed by the magnets. Since the entire diaphragm is driven at the same time there is no breakup modes mechanical filtering transmission delay, or local resonances that can negatively impact sound quality.
A diaphragm that is uniform and flat can also accelerate more quickly 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 more quickly a driver's diaphragm moves and the greater power they can exert. This results in planar magnet drivers having an improved response to bass and superior detail retrieval.
The advantages of a planar magnetic driver are not without cost. Because they feature a complex motor system and a large diaphragms, they generally cost more than dynamic drivers, are heavier and require a higher-powered amplifier to function effectively. However, many planar magnetic headphone manufacturers are able to make the most of their technology to create premium headphones that are priced competitively. Audeze LCD-4, HiFiMAN Susvara are some examples.
High Sensitivity
Planar drivers differ from the moving coil drivers used in most headphones or IEMs in that they employ a flat membrane instead of the traditional cone or dome membrane. When an electrical signal is passed through it, it interacts with magnets on both sides of the diaphragm. It produces sound waves by bouncing the diaphragm. The flat nature of the diaphragm allows it to react quickly to sound and generate an array of frequencies, from bass to highs.
The main benefit of the planar magnetic design is that it's much more sensitive than other kinds of headphone drivers, which utilizes a diaphragm that is that can be several times more powerful than a typical headphone. This allows you to hear all the details in your music.
Planar magnetic drivers also create an extremely constant driving force throughout the diaphragm. This prevents breakup and produces an undistorted, smooth sound. This is particularly important for high-frequency sounds where the sound's breakup can be very audible and distracting. In the FT5 this is accomplished by utilizing a highly advanced material called polyimide, which is extremely light and robust, as well as a sophisticated conductor pattern that eliminates inductance intermodulation distortion.
OPPO's planar magnetic drivers also have much better phase coherence, which means that when a wavefront enters our ear canal, it is an unaltered, flat shape. Dynamic drivers have a spherical-shaped wavefront, which disrupts the coherence of the signal, which result in less-than-perfect reconstructions the highest frequencies, particularly at higher frequency. This is another reason why the OPPO headphones sound so authentic and natural, and extremely accurate.
Wide Frequency Response
A planar magnetic diaphragm can be used to reproduce sounds at greater frequency than conventional dynamic drivers, thanks to their diaphragms are thin and lightweight. is moved in a controlled manner. This allows them to offer high-quality transient response, which makes them a perfect choice for audiophiles who require quick responses from their headphones and speakers to reproduce the finest details in music.
The flat structure also provides them with an even soundstage than headphones that have coiled dynamic drivers. They are also less prone to leakage - the sound that escapes from headphone cups into the surrounding environment. In certain situations, this could be a problem since it can distract the listener and make them lose their focus while listening to music. In other instances, it can be beneficial since it allows listeners to enjoy music in public spaces without worrying about disturbing people nearby.
Instead of putting the coil that is behind a diaphragm that is shaped like cones the planar magnetic headsets feature an array printed on a thin layer of the diaphragm itself. The conductor is hung between two magnets. When an electrical signal is applied to it, the conductor becomes electromagnetic, and the magnetic forces on each side of the diaphragm to interact with each other. This is what causes the diaphragm to vibrate and create an audio wave.
The low distortion is due to the uniform motion of the lightweight, thin diaphragm and the fact that force is evenly distributed across its surface. This is an improvement over traditional dynamic drivers, which are known to cause distortion when you are listening.
Some high-end headphones still use the old school moving coil design, however the majority of HiFi audio enthusiasts are now using a technology that was long forgotten and a new generation of incredible sounding planar magnetic headphones. Some of these headphones are extremely expensive and require a premium amplifier to provide power, but for those with the money they offer an amazing experience that's unrivalled by any other headphone. They offer a rich clear, clear sound that's free of distortion that can be found in other types of headphone.
Minimal Inertia
Due to their construction the planar magnetic diaphragms are extremely light and can move much more quickly than conventional drivers. They reproduce audio signals with greater accuracy and can be tuned to a larger range. They also produce a more natural sound and have less distortion than traditional dynamic speakers.
The two rows of magnets inside a planar magnetic driver generate equal and uniform magnetic forces across the entire surface of the diaphragm. This eliminates unwanted and unnecessary distortion. Because the force applied to the diaphragm's light weight is distributed evenly, it can be controlled more precisely. This allows the diaphragm to be able to move in a precise pistonic motion, resulting in an accurate and smooth music reproduction.
They also have the capability of achieving high levels of performance with minimal weight. This makes them perfect for use as a portable headphone. They can also be made to provide an array of frequencies, from deep bass to high-frequency sounds. Audio professionals love them for their broad frequency response and precise sound.
In contrast to dynamic drivers, which utilize coils to push against the diaphragm and vice versa, planar magnetic drivers have no mechanical components that could meet with eac
