How Do Magnet Planar Headphones Work?

If you've not yet tried a pair headphones that utilize magnetic drivers with planar design it might be difficult to get your mind around how they function. In contrast to the voicecoil actuator which drives a stiff cone back and back the planar magnetic drivers use two flat magnets sandwiching an incredibly thin diaphragm that is made of conductors.

Diaphragm

Contrary to a traditional headphone driver with dome or cone-shaped diaphragm, a magnetic planar has a flat piece of flexible film. The film is etched with conductors that react to magnets that are placed on either side of the membrane. The diaphragm reacts and moves when the magnetic field generated by these magnets gets triggered by the electrical signal that runs through the wires. This motion creates sound waves which are later heard by you.

The diaphragm of the human body is a dome-shaped muscle membranous structure that separates the thoracic (chest) and abdominal cavities. It is the main respiratory muscle and is involved in the process of inspiratory action (exhaling air), such as breathing and coughing, sneezing, crying, laughing vomiting, and parturition. The diaphragm also plays an important role in expulsive movements, such as urinating, defecating and pushing the fetus out during birth.

Due to the ultra-light and thin nature of a planar diaphragm, it is much more responsive to changes in the audio signal than dynamic drivers. Planar magnetic headphones produce more delicate and precise sound than dynamic drivers.

One of the downsides of planar magnetic headphones is that they tend to have a bit more leakage than their dynamic counterparts, especially at higher volumes. This is because the movement of the diaphragm inside the magnet headphone causes a portion of the audio to be pushed outwards and toward the listener.

It is not a big deal if you use headphones only in quiet settings or to watch films. But it can be annoying when you are listening to music or in public use. There are fortunately, some excellent options for reducing the amount of leakage like the Audeze LCD-4 or HiFiMAN Sundara. Wisdom Audio, for example is at the forefront in the development of PMD technology. They have put in a lot of effort to address issues with this kind of headphone. This is why they have patented various innovations that you see in their products. Their new flex-circuit-based planar wounding overcomes the limitations that stamped copper windings must overcome to provide a higher utilization.

The Conductors

The conductors are what connects the diaphragm to the magnets and they are the ones responsible for creating the sound you hear. These are usually made from a combination copper and aluminum. These are then wound around the central magnetic core which is enclosed by the diaphragm and supported by the frame of the headphone. The magnetic core is a cylindrical form of magnetic element and can be made from any material, but it is most commonly produced with Neodymium. The core is the central component of any planar audio driver. It consists of nested layers with an helix circular in size, ranging from 10-20mm in diameter.

Planar magnetic drivers have the advantage of creating a wider soundstage compared to their more dynamic counterparts. This is due to the fact that when an audio signal arrives in the diaphragm, it vibrates across the entire area instead of the tiny space that is connected to the voice coil. This greater surface area results in lower distortion levels, particularly at higher volume.

A magnet planar's ability to respond quickly to changes in the audio signals is a crucial feature. This makes it easier to reproduce a variety of frequencies, and also produces an even more realistic and detailed sound. This is an excellent feature for audiophiles who love music that includes a variety of instruments and Magnet Planar vocals.

The stacking design of planar magnetics reduces the variation between parts which makes them ideal for mission-critical applications that require high reliability. They are more consistent and have less distortion of the magnetic field in comparison to wirewound magnets. This is essential to the performance of electronic devices.

The Magnets

A magnet is a material that has magnetic properties. It can exert an attraction or repelling force on certain materials such as iron and nickel. It also attracts and repel electrical conductors. This phenomenon is referred to as magnetism. It is produced in permanent, temporary or electromagnets. Magnets are employed in a variety of applications, such as electronic devices like mobile phones, headphones and laptop computers.

Planar magnetic driver technology, in contrast to traditional dynamic drivers or balanced armatures that push an extremely rigid and stiff diaphragm with an electric voice coil to create the sound wavefront, employs an extremely thin and flexible diaphragm. The diaphragm oscillates and creates a flat sound wavefront instead of a spherical focused one, as is common in the majority of headphones and speakers. This results in a more clear and more spacious soundstage, and is recognized for its rich bass.

The main disadvantage of planar magnetic drivers is that the large magnets they hold require plenty of power. This makes them more heavy and bulkier than other headphones drivers. Many planar magnetic drivers need an amplifier to function correctly.

This amplifier must be designed to match the output power of the planar magnetic driver to give the best listening experience. Additionally, the amplifier must have a sufficient input impedance to drive the planar magnetic driver at its highest output frequency.

The planar earphones magnetic driver is usually designed to be dipole (radiating equally and in opposite phase between the front and back of the speaker, as ESLs do) or a monopole (radiating only in the direction of the forward similar to traditional headphones). The most popular model is a bipole, with one north and one south pole. Its shape makes it easy to fabricate as a single piece of metal and is very effective in producing a strong 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 drivers. They are utilized in high-end headphone systems where sound accuracy matters. They are also used in audio equipment that is designed for professional use, like microphones and loudspeakers. They are also perfect for medical imaging and other sensitive applications requiring high-quality precision.

The Seal

To perform well for optimal performance, planar drivers need to be sealed very tightly and precisely. A small leak can dramatically reduce sound performance and even cause distortion. It takes a lot of effort to design the ideal seal for planar driver.

Planar magnetic headphones, unlike many other types of headphones, should not have any gaps within the enclosure for acoustics. This is because gaps cause the diaphragm to resonate at multiple frequencies at the same time. This is known as crosstalk and can cause the entire sound quality to suffer significantly.

The most popular type of seal for planar magnetic headphones is the rubber ring seal. This seal can stop air leaks with great efficiency. It is also extremely durable and can last for a long period of time. However it is crucial to remember that this type of seal can sometimes create a hollow sound. If you are planning to use a planar magnetic headphone, it's important to select a high-quality seal.

Another alternative for a planar magnetic driver is the liquid crystal display (LCD) seal. This is a higher-end kind of seal that has been designed to prevent the formation of gaps. It is also designed to withstand a significant amount of pressure. It is a great choice for audiophiles looking for high-quality sound quality.

One benefit of LCD headphones is that they can offer an extremely clear and detailed sound. This is particularly the case with high-end models such as the Audeze LC-4 and HiFiMAN Susvara. However, it is also possible to find inexpensive LCD headphones that provide similar high-quality sound.

It is also important to remember that a planar magnetic headphone can generate a greater sound pressure than standard dynamic headphones. The way they are built is the main reason. planar magnetic speakers magnetic headphones differ from dynamic headphones because they are equipped with two magnets that pull against the diaphragm. This creates a powerful force that can generate extremely high frequencies.

Planar magnetic drivers, which are a relatively recent technology in the market for headphones are a revolutionary product. They have already begun to revolutionize the way that listeners enjoy music. They have high-quality sound and are comfortable to wear. They are also easy to adjust.
