How a Planar Magnetic Diaphragm Headphone Driver Works

In the past, dynamic drivers used a voice coil that was attached to the center of a conical dialephragm. When an electrical signal is passed through the voice coil it causes the diaphragm to move.

The force is only applied to a tiny portion of the diaphragm, and it's difficult to move several points simultaneously. This leads to breakup modes that can lead to distortion.

Detailed Sound

Many audiophiles are looking to get a detailed sound from their headphones. This is possible by using a planar diaphragm. This type of headphone operates in a similar manner to dynamic cone drivers, but with much more modern technology.

A planar diaphragm is a flat structure embedded in the frame of a headphone and made of a thin lightweight material. It's designed to be as homogeneous as possible, and its flat surface allows an uniform distribution of pressure across the entire surface which improves sound clarity.

The flat design creates a more spacious soundstage. A more precise wavefront results in better sound staging that can help locate the exact location of an instrument or vocal on the track. This is a major benefit over the more spherical waves typically of dynamic drivers.

A planar diaphragm differs 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 of magnets on each side of its flat surface. The diaphragm is vibrating and emits sound when the current that flows through the voice coil is absorbed by these magnets. Because the entire diaphragm can be driven at the same time there is no breakup modes, mechanical filtering transmission delay or shinhwapack.co.kr local resonances that can negatively affect the quality of sound.

A diaphragm that is smooth and uniform can also accelerate more quickly than a more substantial, thicker one used in dynamic drivers. The laws of physics state that force is proportional to mass and acceleration, so the faster a diaphragm can move and the greater power it will exert. This gives planar magnetic drivers a more accurate bass response and better detail retrieval.

Of course, the benefits of a planar magnetic driver don't come at a cost. Since they come with a complex motor system and a large diaphragm, they usually cost more than dynamic drivers, are bulkier and require a higher-powered amplifier to work effectively. Many planar magnetic headphone makers are able to take advantage of their technology and create high-performance headphones at a price that is competitive. Audeze LCD-4, HiFiMAN Susvara are some examples.

High Sensitivity

Planar drivers differ from moving coil drivers that are used in the majority of headphones or IEMs in that they use a flat membrane instead of the traditional dome or cone shaped membrane. As an electrical signal moves through, it interacts both with the magnets and diaphragm to produce sound waves. The flat nature of the diaphragm permits it to respond quickly to sound and can produce a wide range of frequencies, from lows to highs.

A key benefit of a closed-back planar magnetic headphones magnetic design is that it's more sensitive than other types of headphone drivers. They may utilize a diaphragm that can be several times larger in volume than a standard planar headphone. This gives you an amazing amount of dynamic range and clarity that allows you to hear every detail that your music can offer.

In addition that, planar magnetic drivers create an extremely uniform driving force across the entire diaphragm that eliminates breakup points, and provides an uncluttered sound that is free of distortion. This is especially crucial for high-frequency sounds where breakup can be audible and distracting. In the FT5 the way this is achieved is through the use of a sophisticated material called polyimide, which is extremely light and robust, as well as a specialized conductor pattern that eliminates the inductance associated intermodulation distortion.

OPPO's planar magnet drivers also have better phase coherence. This means that when a sound wavefront hits our ear, it's flat and headphonesshop.Uk unaltered. Dynamic drivers have a spherical-shaped wavefront, which disrupts the coherence of the signal, which results in less-than-perfect reconstructions of the highest frequencies, particularly at higher frequency. OPPO headphones sound extremely natural and realistic.

Wide Frequency Response

Planar magnetic diaphragms are able to reproduce sounds at much higher frequencies than traditional dynamic drivers. This is because their diaphragm is thin and light in weight. moves very precisely. This allows them to provide excellent transient response, which makes them a great choice for audiophiles that require rapid response from their speakers and headphones to reproduce the finest nuances in music.

This flat structure gives them a more even soundstage than traditional headphones that employ a dynamic driver that is coiled. In addition they are less susceptible to leakage, which is the sound that escapes from the headphones and out into the environment around you. In some cases this can be a problem because it can distract listeners and disrupt their concentration when listening to music. In other situations it can be beneficial since it lets listeners enjoy their music in public areas without worrying about disturbing other people near by.

Rather than using a coil that is placed behind a cone-shaped diaphragm planar headphones are made up of an array of conductors printed on the extremely thin film of the diaphragm. The conductor is suspended in between two magnets and when an electrical signal is applied to the array, it transforms into electromagnetic and causes the magnetic forces on either side of the diaphragm to interact with each with each other. This is what makes the diaphragm vibrate and create the sound wave.

The uniform movement of the diaphragm, which is lightweight and the fact that force is evenly distributed across its surface, means that distortion is extremely low. This is a significant improvement over traditional dynamic drivers which are known to produce distortion at high listening levels.

Some high-end headphones use the old-fashioned design of moving coils. However, the majority of HiFi audiophiles are embracing this long-forgotten technology to create a new generation of planar magnetic headphones that produce a stunning sound. Certain models require a high-end amp to power them. But for those who can afford it, they offer an experience unlike any other headphones. They have a deep clear, clear sound that's free from the distortion inherent in other headphone models.

Minimal Inertia

Due to their construction, planar diaphragms can move faster and are less heavy than conventional drivers. This means they can reproduce audio signals with greater precision and can be tuned for a wider range of frequencies. They also give a natural sound with less distortion than traditional loudspeakers.

The dual rows in a planar magnet driver create the same and uniform force across the entire diaphragm surface. This will eliminate any unnecessary and unwanted distortion. The diaphragm's weight can be more easily controlled since the force is evenly distributed. This permits the diaphragm to move in a precise pistonic motion.

They are also capable of achieving high levels of performance while carrying minimal weight. This makes them ideal for headphones that can be carried around. In addition, they can be made to provide the widest range of frequencies, ranging from deep bass to high-frequency sounds. The wide frequency response and accurate sound reproduction make them a popular choice for audio professionals.

Planar magnetic drivers differ from dynamic drivers that use coils to push the diaphragm. They don't have any mechanical parts which can cause distortion. This is due to the fact that the flat array of conductors is placed directly on the diaphragm rather than being enclosed in a coil behind.

A planar magnetic driver, in contrast can drive a small and light diaphragm with an extremely powerful magnetic force, without energy loss. This means that the diaphragm can be driven with an even pressure, preventing it from bending and 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 an object affects its moment of inertia minimum. Longer and thinner objects have lower moments of inertia.
