How a Planar Magnetic Diaphragm Headphone Driver Works

Traditionally, dynamic drivers have a voice coil attached to the center of the diaphragm conical. When electrical signals pass through a voice coil, the diaphragm shifts.

The force is applied to a tiny portion of the diaphragm, and it's hard to move different points simultaneously. This can lead to breakup patterns which can cause distortion.

Sound Detail

Many audiophiles are looking to get an authentic sound from their headphones. A great way to achieve this is by using a planar magnetic diaphragm. This kind of headphone functions in a similar manner to cone drivers that are dynamic, but with more modern technology.

A planar diaphragm has flat structures that are built into the headphone's frame. It's constructed of a light, thin film-like material. It's designed to be as flat and uniform as 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 precise soundstage is achieved by a more focused wavefront. This helps determine the exact location where a vocal or instrument is situated on the track. This is a major benefit over the more spherical wavefront typically of dynamic drivers.

A planar diaphragm differs from traditional dynamic drivers that employ a voice-coil that is anchored to the cone's central point composed of plastic or paper. Instead, it uses a series magnets on either side of its flat surface. The diaphragm vibrates and produces sound when the current that passes through the voice coil interacts with these magnets. Because the entire diaphragm can be driven at once, there are no breakup modes mechanical filtering transmission delay, or local resonances that could negatively impact sound quality.

A diaphragm with a flat and uniform shape can also be accelerated faster than the thicker and more heavy ones used in dynamic drivers. The laws of physics state that force is proportional to mass and acceleration, which means the faster a diaphragm will move and the greater power it can exert. This gives best planar magnetic iem magnet drivers a more accurate response to bass 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, weigh more and require a more powerful amplifier to work properly. Many manufacturers of planar magnetic headphones can take advantage of their technology and design high-performance headphones at a price that is competitive. Examples include the Audeze LCD-4 and HiFiMAN Susvara.

High Sensitivity

Planar drivers differ from moving coil drivers that are used in the majority of headphones or IEMs in that they employ a flat membrane instead of the conventional cone or dome membrane. When an electrical signal is passed through it, it interacts with magnets on both sides of the diaphragm. It creates sound waves by vibrating the diaphragm. The flat diaphragm can react quickly to sound and produce a broad range of frequencies ranging from lows to highs.

Planar magnetic headphones are more sensitive than other drivers for headphone that use diaphragms up to several time larger than the typical planar design. This gives you an amazing quantity of clarity and dynamic range which allows you to appreciate every detail that your music has to provide.

Planar magnetic drivers also create an extremely constant driving force that is evenly distributed throughout the diaphragm. This eliminates breakup, and creates an undistorted and smooth sound. This is particularly crucial for high frequencies in which the presence of breakups can be extremely audible and distracting. In the FT5 this is accomplished by using an advanced material called polyimide. It is both ultra-light and extremely robust, as well as a sophisticated conductor pattern that eliminates the inductance intermodulation distortion.

The OPPO's planar magnetic driver also have much better phase coherence, meaning that when a wavefront enters the ear canal, it's an unaltered, flat shape. Dynamic drivers have a spherical-shaped wavefront, which alters the coherence of the signal, which causes less-than-perfect reconstructions of high-frequency signals, particularly at high frequency. OPPO headphones sound very real and natural.

Wide Frequency Response

Planar magnetic diaphragms have the ability to reproduce sounds at much higher frequencies than traditional dynamic drivers. This is due to their diaphragm is thin and light in weight. moves very precisely. This allows them to provide an excellent transient response. This makes them an exceptional choice for audiophiles who require rapid response from their headphones and speakers to reproduce the finest detail in music.

This flat structure also allows them to have a more uniform soundstage than regular headphones that use coiled dynamic drivers. In addition, they are less prone to leakage, which is the sound that escapes the headphone cups and into the surrounding area. In certain situations, this is a problem because it can distract listeners and disrupt their concentration when listening to music. In other situations it can be beneficial since it allows listeners to enjoy their music in public spaces without worrying about disturbing other people nearby.

Instead of using a coil behind a diaphragm that's shaped like cones the planar magnetic planar speakers headsets feature an array of printed patterns on a thin layer of the diaphragm itself. The conductor is suspended in between two magnets and when an electrical signal is applied to this array it becomes electromagnetic and causes the magnetic forces on either side of the diaphragm to interact each one. This is what makes the diaphragm vibrate and create an audio wave.

The low distortion is due to the consistent movement of the thin, lightweight diaphragm as well as the fact that force is evenly dispersed across its surface. This is a significant improvement over traditional dynamic drivers, which are known for producing distortion at very high levels of listening.

Some high-end headphones use the old-fashioned moving coil design, but the majority of 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 require a top-of-the-line amplifier to power them. For those who can afford it, they provide an experience that is unlike any other headphone. They deliver a deep and detailed sound without the distortion that is common with other kinds of headphones.

Minimal Inertia

Due to their construction the diaphragms of planar diaphragms move faster and are less heavy than conventional drivers. This means they can reproduce audio signals with greater precision and can be tuned to more frequencies. They also provide an authentic sound and have less distortion than traditional dynamic speakers.

The dual rows of magnets inside a planar magnetic driver generate equal and uniform magnetic forces across the entire diaphragm's surface. This reduces unnecessary and unwanted distortion. Since the force exerted on the lightweight diaphragm is evenly distributed, it can be controlled more precisely. This allows the diaphragm vibrate in a precise pistonic motion.

They also have the capability of achieving high levels in performance with very little weight. This makes them perfect for headphones that can be carried around. In addition, they can be designed to offer a wide range of frequencies, from deep bass to high-frequency sounds. The wide frequency response and accurate sound reproduction make them a favourite among audio professionals.

Planar magnetic drivers are different from dynamic drivers that utilize 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 sits directly on the diaphragm's top, rather than in the form of a coil that is behind.

A planar magnetic driver however it can drive a light and thin diaphragm by applying a tremendous magnetic force without any energy loss. The diaphragm is an extremely thin and lightweight membrane is driven by the magnetic field, best Planar Magnetic iem which exerts an unchanging pressure. This prevents it from bending or causing distortion.

The moment of inertia defines the resistance to rotation of an object. It can be calculated from the formula I = mr2. The shape of an object affects its minimum moment of inertia. Longer and thinner objects have lower moments of inertia.
