How Do Magnet Planar Headphones Work?

If you've not yet tried a pair headphones with magnetic drivers with planar design it might be difficult to wrap your head around how they function. Contrary to the voicecoil motor that drives a stiff cone back and back the planar magnetic drivers use two flat magnets that are sandwiched between an incredibly thin diaphragm that is made of conductors.

The Diaphragm

Unlike a traditional dynamic headphone driver, which has dome or cone shaped diaphragm, a magnet planar is a flat piece of flexible film. The film is etched with conductors that react to magnets on either side of the membrane. The diaphragm reacts and moves when the magnetic field generated by these magnets is triggered by the electrical signal that flows through the wires. This causes sound waves that can be heard by you.

The diaphragm in the human body is a dome-shaped muscular membrane that separates thoracic (chest), and abdominal cavities. It is the main muscle of respiration and is involved in inspiratory actions (exhaling air), such as breathing, sneezing, coughing, laughing, crying, vomiting, and parturition. The diaphragm is also vital for expulsive actions, including the act of urinating and bowel movements and pushing out the fetus during birth.

A planar magnetic diaphragm is much more sensitive to changes in audio signals than dynamic drivers due to its light weight and thinness. These headphones have a sound that is more precise and delicate than what you get with a dynamic driver.

One of the drawbacks of planar magnet headphones is that, at higher volumes, they tend to leak more than their dynamic counterparts. This is because the movement of the diaphragm within a planar magnetic headphone causes a portion of the audio to be pushed outwards and then towards the listener.

It's not a huge deal if you use headphones in quiet areas, or to watch movies. But it can be a nuisance for public or active listening usage. There are a few options that can limit the amount of leakage. They include the Audeze LCD-4 and HiFiMAN Sundara. Wisdom Audio, for example is a leader in the development of PMD technology. They have been working hard to address issues that arise with this type of headphone. They have patented many innovations that can be seen on their products. Their flex-circuit-based planar-winding technology overcomes the limitations that stamped copper windings must overcome to provide a higher utilization factor.

The Conductors

The conductors are what are planar magnetic drivers connects the magnets to the diaphragm and are responsible for producing the sound that you hear. They are typically made of a mix of copper and aluminum. The diaphragm is then wrapped around the central magnetic core. It is then supported by the headphone's frame. The magnetic core is a circular shaped magnetic element and can be made from any type of material, but it is most commonly produced using Neodymium. The core is the central element of any planar sound driver. It consists of nested layers that form an elongated helix that is 10-20mm in diameter.

Planar magnetic drivers have the advantage of having a wider soundstage compared to their more dynamic counterparts. This is due to the fact that when an audio signal arrives, the entire diaphragm vibrates instead of just the small space that is connected to the voice coil. This larger surface area also results in lower distortion levels, particularly at higher volumes.

A magnet planar's ability to react quickly to changes in the audio signals is another important feature. This allows for a greater spectrum of frequencies to be reproduced, as well as a more realistic sound. This is an excellent feature for audiophiles who enjoy music that incorporates a variety of instruments and vocals.

Furthermore, the stacked design of a planar magnetic reduces part-to-part variation and is perfect for applications that require high-reliability. Compared to traditional wirewound magnetics, these offer improved consistency with lower magnetic field distortion, which is crucial for the success of any electronic device.

The Magnets

A magnet is a substance that has magnetic properties. It can cause a repulsive or attractive force on certain materials, such as iron, nickel, cobalt and some steels. It also attracts and repel certain electrical conductors. This phenomenon is known as magnetism. It is produced by permanent, electromagnets or temporary magnets. Magnets are employed in a variety of applications, including electronic devices like headphones, mobile phones and laptop computers.

In contrast to traditional balanced armature and dynamic drivers that push a rigid diaphragm that is connected to a voice coil, the planar magnetic driver technology employs an extremely thin, light, flexible diaphragm that vibrates to create an unidirectional sound wavefront, instead of the spherical focused wavefront common in most headphones and speakers. This creates a cleaner and more spacious soundstage, and is recognized for its rich bass.

The main disadvantage of planar magnetic drivers is that they require quite a lot of power to move the huge magnets inside which makes them heavier and heavier than other kinds of headphone drivers. This is why many planar magnetic drivers require a separate power amplifier to function properly.

The amplifier should be constructed to match the output power of the planar magnetic driver to provide the optimal listening experience. The amplifier should also have an impedance that is high at the input in order to drive the planar magnet driver to its maximum output.

The planar magnetic drive is usually designed as either dipole, which radiates equally and in opposing phases in front and behind the speaker (like ESLs) or a monopole, which emits only in the forward-facing direction (more than traditional headphones). The most popular design of a planar magnetic driver is a bipole, with two poles that alternate on the north and south. Its shape allows it to be made as one piece of metal and creates a very solid field in the center of the faceplate.

Because of their size and effectiveness, planar magnetic drivers have a lower distortion than other types of headphone drives. They are commonly used in premium headphone systems where sonic accuracy is crucial. They are also used in professional audio equipment such as loudspeakers and microphones. They are also ideal for medical imaging and other sensitive applications that require high-quality precision.

The Seal

To be effective, planar drivers must be sealed very tightly and precisely. A small leak could cause a significant change in the quality of sound and could cause distortion. Therefore, a great deal of work is required to create the proper seal for drivers with planar designs.

Contrary to many headphone designs, planar magnetic headphones must not have gaps in the acoustic enclosure. This is because gaps cause the diaphragm's resonance to be influenced by different frequencies simultaneously. Crosstalk is a problem that can affect the sound quality.

The most popular type of seal for planar magnetic headphones is the rubber ring seal. This seal is very effective at preventing air leaks. It is also extremely durable and can last for a long time. It is important to remember that this type of seal can sometimes create an unnatural sound. If you are planning to use a planar magnet headphone, it's important to select a high-quality seal.

The liquid crystal display (LCD) seal is another option for a magnetic driver. It is a specialized seal that is designed to stop gaps from forming. It's also designed to withstand a large amount of pressure. It is a great choice for audiophiles who want top-quality sound quality.

LCD headphones can provide clear and crisp sound. This is especially the case for Magnet Planar headphones that are high-end, like the Audeze LCD-4 and HiFiMAN Susvara. But, it's also possible to find low-cost LCD headphones that have similar audio quality.

It is also important to know that the planar magnetic headphone may generate a greater sound pressure than conventional dynamic headphones. The way they are constructed is the reason for this. Planar magnetic headphones differ from dynamic headphones because they contain two magnets that pull against the diaphragm. This creates an enormous force that can generate extremely high frequencies.

Planar magnetic drivers, a relatively new technology in the world of headphones are a revolutionary product. They have begun to change the way people listen to music. These headphones offer high-quality sound and are comfortable to wear. They are also easy to adjust.
