How a Planar Magnetic Diaphragm Headphone Driver Works Typically, dynamic drivers comprise a voice coil attached to the center of the diaphragm conical. When an electrical signal is passed through the voice coil it causes the diaphragm to move. However, the force exerted is limited to a small area, and it's hard for various points on the diaphragm to move at the same at the same time. This can cause distortions caused by breakup patterns. Sound Detail Many audiophiles would like to hear a detailed sound through their headphones. This can be accomplished by using a planar diaphragm. This kind of headphone driver functions in a similar way to cone drivers with dynamic characteristics however, with more modern technology behind it. A planar diaphragm is a flat piece of material embedded in the frame of a headphone and constructed of a light, light material. It is designed to be as flat and uniform as possible. This ensures an even pressure distribution across the entire surface. A flat planar magnetic diaphragm's design provides a greater soundstage. A more focused soundstage can be created by a more precise wavefront. This helps you pinpoint the location of an instrument or vocal is on the track. This is a major benefit over the more spherical wavefront typical of dynamic drivers. In contrast to traditional dynamic drivers, which make use of a voice coil located to the center of a paper or plastic cone, a planar diaphragm utilizes a series of magnets on both sides of its flat face. The diaphragm vibrates and produces sound when the current that passes through the voice coil is absorbed by the magnets. The entire diaphragm is driven simultaneously. This eliminates breakup modes mechanical filters, transmission delays and local resonances that can have a negative impact on sound quality. A flat and uniform diaphragm can also be accelerated more quickly than the thicker and heavier ones that are used in dynamic drivers. According to the laws of physics, force is proportional mass and acceleration. This means that the more quickly a driver's diaphragm moves and the greater power they are able to exert. This gives planar magnet drivers a more accurate response to bass as well as superior detail retrieval. The advantages of a planar magnet driver are not without cost. Since they come with a complex motor system and a large diaphragm, they typically cost more than dynamic drivers, are bulkier and require a stronger amplifier to perform properly. Many manufacturers of planar magnetic headphones benefit from their technology to create premium headphones at competitive prices. Examples include the Audeze LCD-4 and HiFiMAN Susvara. High Sensitivity The planar driver is different from the moving coil drivers found in the majority of headphones and IEMs, in that it utilizes a flat diaphragm, instead of a dome-shaped or cone-shaped membrane. As an electrical signal passes through it, it interacts with magnets on both sides of the diaphragm. This produces sound waves by vibrating the diaphragm. The diaphragm with a flat surface can react quickly to sound and can produce a wide range in frequencies from lows to highs. The main benefit of the planar magnetic design is that it's much more sensitive than other kinds of headphone drivers. They utilizes a diaphragm that is that is up to a few times more powerful than a typical headphone. This lets you be able to hear every detail in your music. Planar magnetic drivers also create a very consistent driving force that is evenly distributed throughout the diaphragm. This reduces breakup and produces an undistorted, smooth sound. This is especially crucial for high-frequency sounds where breakup can be audible and distracting. In the FT5, this is achieved through the use of a sophisticated material called polyimide. It is both ultra-light and extremely robust, as well as a specialized conductor pattern that blocks inductance intermodulation distortion. The OPPO's planar magnetic driver also have a higher degree of phase coherence, which means that when a wavefront enters our ear canal, it's a perfectly flat and unaltered shape. Dynamic drivers have a spherical-shaped wavefront, which alters the coherence of the signal, which result in less-than-perfect reconstructions high-frequency signals, particularly at higher frequencies. OPPO headphones sound incredibly real and natural. Wide Frequency Response A planar magnetic diaphragm has the ability to reproduce sounds at wider frequencies than conventional dynamic drivers, thanks to their diaphragm is thin and light in weight. moves in a very controlled way. This allows them to offer an excellent transient response. This makes them a perfect option for audiophiles who need quick responses from their headphones and speakers to reproduce the finest nuances in music. The flat design gives them a more even soundstage than headphones that employ a dynamic driver that is coiled. In addition they are less prone to leakage, which is the sound that escapes from the headphones and out into the surrounding environment. In some instances, this can be a problem, as it can distract the listener and cause them lose their focus while listening to music. In some cases it can be a problem because it can distract listeners and alter their focus while listening to music. Instead of using a coil behind a cone-shaped diaphragm planar headphones are made up of conductors arranged on the extremely thin film of the diaphragm. The conductor is then suspended in between two magnets and when an electrical signal is applied to this array, it turns into electromagnetic and causes the magnetic forces on the opposite side of the diaphragms to interact with each with each other. This is the reason why the diaphragm begins to vibrate, creating a sound wave. The low distortion is due to the uniform movement of the lightweight, thin diaphragm, and the fact that the force is evenly dispersed across its surface. go to the website is a significant improvement over traditional dynamic drivers which can cause distortion at very high levels of listening. Some premium headphones utilize the old-school moving coil design. However, most HiFi audiophiles are embracing this long-forgotten technology to create a new generation of planar magnetic headphones that sound amazing. Some of these models are incredibly expensive and require a premium amplifier to provide power however for those with the money they offer an exceptional 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 As a result of their construction they are extremely light and can move faster than traditional drivers. They reproduce audio signals with greater accuracy and can be tuned to a greater range. They also produce a natural sound with less distortion than traditional dynamic loudspeakers. The two rows of magnets inside a planar magnetic driver create equal and uniform magnetic forces across the entire diaphragm's surface. This eliminates any unwanted and unnecessary distortion. Because the force applied to the diaphragm's light weight is distributed evenly and evenly, it can be controlled more precisely. This lets the diaphragm move in an exact pistonic motion. They also have the capability of achieving high levels in performance with minimal weight. This makes them perfect for portable headphone. Additionally, they can be made to provide the widest range of frequencies, ranging from deep bass to high-frequency sounds. Audio professionals appreciate them for their wide frequency response and precise sound. Planar magnetic drivers differ 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 conductors' flat array rests directly on the diaphragm, instead of in a coil behind it. A planar magnetic driver in contrast, can drive a thin and lightweight diaphragm with an extremely powerful magnetic force with no loss of energy. In the end, the diaphragm is driven by an even pressure, preventing it from deforming and causing distortion. The moment of inertia is a crucial property that describes an object's resistance to rotation. It can be calculated from the formula I = mr2. The shape of an object influences its moment of inertia minimum. Longer and smaller objects have lower moments of inertia.
