How Do Magnet Planar Headphones Work?

It could be difficult for you to comprehend how planar magnetic drivers work in case you've never worked with the two. In contrast to the voicecoil actuator which drives a stiff cone back and back using a cone, planar magnetic drivers utilize two flat magnets sandwiching a thin diaphragm made of conductors.

imageDiaphragm

Contrary to a traditional headphone driver with 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 placed between the two sides of the membrane. The diaphragm moves and reacts when the magnetic field generated by these magnets is stimulated by the electrical signal that flows through the wires. This movement creates soundwaves that you then hear.

The human diaphragm is a dome-shaped membranous muscular structure that separates the thoracic (chest) and abdominal cavities. It is the principal respiratory muscle and is responsible for inhalation actions, like breathing coughing and sneezing and crying, laughing vomiting, and parturition. The diaphragm also plays a role in expulsive movements like urinating or defecating, and pushing the fetus out during the birth.

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

One of the disadvantages 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 of the movement of the magnet diaphragm of the planar headphones which causes some audio to be pushed towards the listener.

This is not an issue if you listen to music in quiet areas or Magnet Planar when watching movies, but it can be a nuisance for public listening and active usage. There are fortunately, some great options to limit the amount of leakage, such as the Audeze LCD-4 or HiFiMAN Sundara. Wisdom Audio, for example is a leader in developing PMD technology. They have put in a lot of effort to solve the issues associated with this kind of headphone. This is why they have patented various innovations that you observe in their products. Their new flex-circuit-based planar wounding overcomes the limitations stamped copper windings must overcome to provide a higher utilization factor.

The Conductors

Conductors are what connect the magnets to the diaphragm and they're responsible for generating the sound you hear. They are usually made of a mix 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 can be made from any material, but it is typically Neodymium. The core itself is the primary component of any planar magnetic audio driver. It consists of a number of nested layers that form an helix that is circular with an area of 10-20mm.

Planar magnetic drivers have the advantage of creating a wider soundstage than their dynamic counterparts. This is because the entire diaphragm is vibrating when an audio signal is received instead of a tiny portion that is attached to the voice coil. This larger surface area results in lower distortion levels, especially at higher volume.

A magnet planar's ability to react quickly to changes in the audio signals is another important characteristic. This allows it to reproduce a variety of frequencies and creates more realistic and detailed sound. Audiophiles who love music with a variety of instruments and vocals will appreciate this feature.

Additionally, the stacked structure of a planar magnet reduces the variability of parts and is suitable for mission-critical applications that require high-reliability. In comparison to wirewound magnetics, they offer improved consistency with lower best magnetic planar headphones field distortion, which is essential to the performance of any electronic device.

The Magnets

Like its name suggests it is an element that has magnetic properties. It can exert an attraction or repelling force on certain materials like nickel and iron. It also can draw or repel certain electrical conductors. This phenomenon is called magnetism. It can be created by permanent, electromagnets or temporary magnets. Magnets are utilized in a variety of applications, including electronic devices like mobile phones, headphones, and Magnet Planar laptop computers.

In contrast to traditional balanced armature and dynamic drivers that use an extremely stiff diaphragm using a voice coil, planar magnetic driver technology uses a thin, light, flexible diaphragm that can vibrate to create a flat sound wavefront instead of the narrow spherical wavefront that is common in headphones and speakers. This results in a larger and more expansive soundstage, and is also recognized for its deep bass.

The biggest drawback of planar headphone drivers is that the huge magnets they contain require plenty of power. This makes them more heavy and bulkier than other types of headphones drivers. Many planar magnetic drivers need an amplifier in order to function correctly.

The amplifier has to 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 to allow it to drive the planar magnet driver to its maximum output.

The planar magnetic driver is generally designed to be either dipole (radiating equally and in a different phase between the front and back of the speaker, like ESLs) or a Monopole (radiating only in the direction of forward similar to traditional headphones). The most popular design is a bi-pole that has one north and one south pole. Its shape allows it to be made as one piece of metal, and creates a solid field in the center of the faceplate.

Planar magnetic drivers are more efficient and have a lower distortion because of their size. This is why they are commonly employed in headphones with high-end features where sonic accuracy is important. They can also be found in professional audio equipment such as microphones and loudspeakers. They are also perfect for medical imaging, and other applications that require high precision.

The Seal

To perform well Planar drivers must be sealed extremely well and precisely. A small leak can greatly impact sound quality and cause distortion. Therefore, a great deal of work goes into creating the correct seal for planar drivers.

Planar magnetic headphones, unlike many other types of headphones, should not have gaps within the enclosure of the acoustic. This is because gaps will cause the diaphragm's resonance to be influenced by different frequencies at the same time. This is referred to as crosstalk, and can cause the overall sound quality to be affected.

The most commonly used seal used for planar magnetic headphones is the rubber rings seal. This seal is able to stop air leaks very effectively. It is also extremely durable and can last a long time. However, it is important to keep in mind that this kind of seal may sometimes produce a hollow sound. If you're planning to use a planar magnetic headphone, you must choose a seal that is of high-quality.

Another option 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 can also stand up to pressures of a great deal. It is an excellent choice for audiophiles seeking premium sound quality.

imageLCD headphones can give a clear and precise sound. This is especially the case with high-end models such as the Audeze LCD-4 and HiFiMAN Susvara. It is possible to find LCD headphones with the same sound at a lower price.
