How Do Magnet Planar Headphones Work?

If you've never tried a pair of headphones that utilize planar magnetic drivers, it may be difficult to wrap your head around the way they function. Planar magnetic drivers employ two flat magnets that sandwich a thin diaphragm with conductors. This differs from the voicecoil actuator, which pushes a stiff cone back and forward.

Diaphragm

Magnet Planars Headphones are flat pieces made of flexible film, which is different from traditional dynamic headphone drivers, which have cone or dome-shaped diaphragm. The film is dotted with conductors on it that interact with magnets that are placed on either side of the diaphragm. The diaphragm reacts and moves when the magnetic field generated by these magnets is stimulated by the electrical signal that flows through the wires. This motion creates sound waves that can be heard by you.

The diaphragm in the human body is a dome-shaped 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 or coughing, sneezing crying, laughing, vomiting, and parturition. The diaphragm is also essential for expulsive actions, including urinating and defecating and pushing the fetus out during delivery.

A planar magnetic diaphragm is more sensitive to changes in audio signals than dynamic drivers due to its ultra-lightweight and thinness. This results in planar magnetic headphones an audio that is more precise and delicate than what you get with a dynamic driver.

One of the drawbacks of planar magnetic headphones is that they are likely to have a bit more leakage than their dynamic counterparts, especially at higher volumes. This is because of the motion of the magnet diaphragm of the planar headphones, which causes some audio to be pushed away from the listener.

It's not a big deal if you use headphones only in quiet environments or to watch films. However, it can be annoying when you are listening to music or in public use. There are, however, very good options available to limit the amount of leakage, such as the Audeze LCD-4 or HiFiMAN Sundara. In addition, some brands like Wisdom Audio are at the forefront of the development of PMD technology and have been working to solve the issues that come with this type of headphone. This is why they have patents on several innovations that you can observe in their products. Their flex-circuit-based planar-winding technology overcomes the limitations stamped copper windings must overcome to give a greater utilization rate.

The Conductors

Conductors link the diaphragm with the magnets and are responsible for the sound you hear. They are typically made of an amalgamation 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 may be made from any material, but the most common is Neodymium. The core is the central element of any planar audio driver. It is made up of several nested layers of a circular helix with a diameter of 10-20mm.

Planar magnetic drivers have the advantage of a larger soundstage compared to their more dynamic counterparts. This is because 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 larger surface area results in lower distortion levels, Planars Headphones especially when the volume is greater.

Another significant feature of a magnet planar is its ability to respond quickly to changes in the audio signal. This makes it easier to reproduce a variety of frequencies, and also produces more realistic and detailed sound. Audiophiles who appreciate music that includes various instruments and vocals will appreciate this feature.

Additionally, the stacked design of a planar magnetic decreases the variability of parts and is suitable for mission critical applications that require high reliability. They offer better consistency and lower magnetic field distortion as compared to wirewound magnetics. This is essential to the performance of electronic devices.

The Magnets

A magnet is a substance that has magnetic properties. It can draw attention or repel force on certain materials, like nickel and iron. It can also attract or repel electrical conductors. This phenomenon is called magnetism. It is produced by electromagnets, permanent or temporary magnets. Magnets are used in many applications, including electronic devices such as mobile phones, headphones, and laptop computers.

Planar magnetic driver technology, unlike traditional balanced armature or dynamic drivers which use a rigid, stiff diaphragm with an electric voice coil to create the sound wavefront, utilizes a thin and flexible diaphragm. This diaphragm vibrates and creates a flat wavefront instead of a narrow spherical one, as is common in the majority of headphones and speakers. This creates a much cleaner and larger soundstage. It is also recognized for its rich bass.

The main disadvantage of planar headphone drivers is that the large magnets they contain require plenty of power. This makes them heavier and more bulky than other types of headphone drivers. A lot of planar magnetic drivers require an amplifier to function correctly.

The amplifier should be designed so that it matches the power output of the planar magnetic driver in order to provide an optimal listening experience. The amplifier must also have an extremely high input impedance to allow it to drive the planar magnet driver at its maximum output.

The planar magnetic driver is usually designed to be dipole (radiating equally and in opposite phase in front of and behind the speaker, like ESLs) or a Monopole (radiating only in the direction of the forward similar to traditional headphones). The most common design is a bi-pole that has one north and one south pole. Its shape lets it be easily fabricated as a single metal piece and produces a very solid field in the center of the faceplate.

Planar magnetic drivers are more efficient and have a lower distortion due to their size. They are often used in high-end headphones where sonic accuracy is important. They are also found in audio equipment that is professional, such as speakers and microphones. They are also ideal for medical imaging and other applications that require high-quality precision.

The Seal

To ensure that planar drivers function well they must be sealed in a very precise and tight manner. A tiny leak can be a major impact on the quality of sound and may cause distortion. It takes a lot of effort to create the right seal for planar driver.

In contrast to the majority of conventional headphone designs the planar magnetic headphones planar should not have any gaps in the acoustic enclosure. This is because gaps could cause the diaphragm's resonance with different frequencies simultaneously. The problem of crosstalk can affect the quality of sound.

The most commonly used seal for planar magnetic headphones is the rubber rings seal. This seal is extremely effective in preventing air leaks. It is also very robust and lasts for an extended period of time. However it is essential to be aware that this kind of seal could sometimes create a hollow sound. It is therefore crucial to select a premium rubber seal if you're planning on using the planar magnetic headphone.

The liquid crystal display (LCD) seal is a different alternative for a magnetic planar driver. This is a more advanced type of seal that is designed to prevent the creation of gaps. It is also designed to withstand a significant amount of pressure. It is a great option for audiophiles looking for top-quality sound quality.

LCD headphones can give a clear and detailed sound. This is particularly relevant for high-end headphones like the Audeze LCD-4 and HiFiMAN Susvara. It is possible to find LCD headphones with the same audio quality at a lower cost.

It is also important to note that a planar magnetic headphone will create a higher volume of sound than traditional dynamic headphones. The way they are built is the reason. Planar magnetic headphones differ from dynamic headphones because they have two magnets that pull against the diaphragm. This can create an enormous force that can create extremely high frequencies.

Planar magnetic drivers, which are a relatively recent technology in the headphone market are an innovative product. They have already started to change the way listeners enjoy music. They have high-quality sound and are comfortable to wear. They are also simple to adjust.
