How Do Magnet Planar Headphones Work?

If you've never tried a pair of headphones that utilize magnetic drivers that planar it might be difficult to wrap your head around how they function. Unlike the voicecoil actuator that drives a stiff cone back and forth using a cone, planar magnetic drivers utilize two flat magnets sandwiching an incredibly thin diaphragm that is that is printed with conductors.

Diaphragm

Magnet planars are flat pieces of flexible film, in contrast to traditional dynamic headphone drivers that have a dome or cone shaped diaphragm. The film is made of conductors which react to magnets placed across the membrane. The diaphragm moves and reacts when the magnetic field generated by these magnets gets triggered by the electrical signal that runs through the wires. This causes soundwaves that you then hear.

The diaphragm of the human body is a dome-shaped muscular membrane that divides the thoracic (chest), and abdominal cavities. It is the main respiratory muscle and is involved in the process of inspiratory action (exhaling air) like breathing or coughing, sneezing crying, laughing vomiting, and parturition. The diaphragm is also vital for expulsive actions, including urinating and defecating and pushing the fetus out during delivery.

Due to the ultra-light and thin nature of a planar magnetic diaphragm it is more sensitive to changes in the audio signal than dynamic drivers. This gives planar magnetic headphones a sound that is more precise and delicate than the sound you get from a dynamic driver.

One of the disadvantages of planar magnet headphones is that at higher volume, they can leak more than their dynamic counterparts. This is due to the movement of the diaphragm within a magnet planar headphone causes some of the audio to be pushed outwards and towards the listener.

This isn't a problem if you only use headphones in quiet settings or when watching movies however it can be a hassle for public listening and active use. There are several options to minimize the amount of leakage. These include the Audeze LCD-4 and HiFiMAN Sundara. Wisdom Audio, for example is a leader in the development of PMD technology. They have put in a lot of effort to resolve issues with this type of headphone. This is the reason they have patented various innovations that you see in their products. Their flex-circuit-based planar-winding technology overcomes the limitations that stamped copper windings must overcome to give a greater utilization.

The Conductors

The conductors are what connects the magnets to the diaphragm and they are the ones responsible for creating the sound you hear. They are typically made from a mixture of aluminum and copper. The diaphragm is then wrapped around the central magnetic core. This is supported by the headphone's frame. The magnetic core is a cylindrical shape magnetic element that can be made from any material, however it is most commonly produced using Neodymium. The core is the primary component of any planar audio driver and consists of a series of nested layers of a circular helix with an area of 10-20mm.

A key advantage of planar magnetic drivers is that they create a much wider soundstage than their dynamic counterparts. This is due to the fact that the entire diaphragm vibrates whenever an audio signal is received, instead of a tiny portion that is attached to the voice coil. This greater surface area results in lower distortion levels, especially at higher volumes.

A magnet planar's ability to respond quickly to changes in audio signals is an additional characteristic. This allows for a greater range of frequencies that can be reproduced, as well as a more authentic sound. This is a fantastic feature for audiophiles who enjoy music that includes a variety of instruments and vocals.

The stacked design of planar magnetics reduces the variability of part-to-part which makes them ideal for mission-critical applications that require high reliability. As compared to wirewound magnetics, these offer greater consistency, with less magnetic field distortion, which is crucial to the performance of any electronic device.

The Magnets

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

Planar magnetic driver technology, unlike traditional balanced armature or dynamic drivers that push a stiff, rigid diaphragm by using a voice coil to create the sound wavefront, utilizes a thin and flexible diaphragm. The diaphragm oscillates and creates a flat wavefront, instead of a spherical focused one, which is the norm in all headphones and speakers. This produces a much more spacious and cleaner soundstage, and is known for its rich bass.

The biggest drawback of planar closed back headphones (https://peatix.com/user/21496703) headphone drivers is that the huge magnets they contain require a lot of power. This makes them heavier and bulkier than other headphones drivers. Many planar magnetic drivers require a power amplifier to work correctly.

The amplifier should be designed so that it matches the power output of a planar magnetic driver order to give the best listening experience. Additionally, the amplifier must have a sufficient input impedance to drive the planar magnetic driver at its maximum output frequency.

The planar magnetic driver is typically constructed to be dipole (radiating equally and in opposite phase in front and behind the speaker, similar to ESLs) or a monopole (radiating only in the direction of the forward and more like traditional headphones). The most commonly used design of a planar magnetic driver is a bipole with alternating poles on the south and north. Its shape permits it to be made as a single metal piece and creates a very solid field in the center of the faceplate.

Planar magnetic drivers are more efficient and have a smaller distortion because of their size. They are commonly used in premium headphone systems where sonic precision is important. They can also be found in professional audio equipment such as microphones and loudspeakers. Due to their unique construction they are also suited for medical imaging and other delicate applications that require extreme precision.

The Seal

To perform well Planar drivers must be sealed very tightly and precisely. A tiny leak can drastically affect sound quality and cause distortion. It requires a lot of effort to create the right seal for planar driver.

In contrast to the majority of conventional headphone designs that are used, planar magnetic headphones should not have any gaps within the acoustic enclosure. This is because gaps cause the diaphragm to resonate at multiple frequencies at the same time. This is known as crosstalk, and it can cause the overall sound quality to suffer significantly.

Rubber rings are the most popular type of seal used for headphones that are planar. This seal is able to stop air leaks very effectively. It is also very robust and lasts for planar closed back headphones a long time. It is important to keep in mind that this type of seal can occasionally produce an unnatural sound. Therefore, it is important to select a premium rubber seal if contemplating using the planar magnetic headphone.

Another alternative to an in-plane magnetic driver is the liquid crystal display (LCD) seal. This is a higher-end type of seal designed to prevent the creation of gaps. It's also designed to withstand a large amount of pressure. It is an excellent choice for audiophiles who want high-quality sound quality.

One benefit of LCD headphones is that they can provide the most clear and precise sound. This is particularly applicable to high-end models such as the Audeze LCD-4 and HiFiMAN Susvara. But, it's also possible to find affordable LCD headphones that have similar sound quality.

It is important to remember that planar magnetic headphones can produce a higher sound pressure than dynamic headphones. This is due to the way they are made. Planar magnetic headphones differ from dynamic headphones in that they contain two magnets that pull against the diaphragm. This can create a powerful force that can produce very high frequencies.

Planar magnetic drivers are a relatively new technology in the headphone industry. They have begun to change the way people listen to music. In addition to their high-fidelity sound they are also very comfortable to wear and are easy to adjust.
