How Do Magnet Planar Headphones Work?

It may be difficult to understand how planar magnetic drivers work if you have never used two. Planar magnetic drivers use two flat magnets that are sandwiched between a thin diaphragm with conductors. This is different from the voicecoil motor, which pushes a stiff cone back and forward.

The Diaphragm

In contrast to a traditional dynamic headphone driver with dome or cone-shaped diaphragm, a magnetic planar is a flat piece of flexible film. The film has conductors etched on it that react with magnets placed on either side of the diaphragm. The diaphragm moves and reacts when the magnetic field created by these magnets is triggered by the electrical signal that runs through the wires. This causes sound waves that are then heard by you.

The diaphragm of the human body is a dome-shaped membrane that divides the thoracic (chest) and abdominal cavities. It is the main respiratory muscle, and is responsible for inspiratory actions, such as breathing, sneezing and coughing as well as crying and laughing vomiting, and parturition. The diaphragm also is essential for expulsive actions, such as urinating and defecating and pushing out the fetus during delivery.

A planar magnetic diaphragm is much more sensitive to changes in audio signals than dynamic drivers because of its ultra-lightweight and thinness. These headphones have a a sound that is more delicate and precise than that you get from a dynamic driver.

One of the downsides 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 planar magnetic headphone causes some of the audio to be pushed outwards and towards the listener.

It's not a big issue if you use headphones in quiet areas or to watch films. However, Magnet Planar it can be annoying for active listening or public use. There are, however, great options for reducing the amount of leakage, like the Audeze LCD-4 or HiFiMAN Sundara. Additionally, certain brands such as Wisdom Audio are at the forefront of developing PMD technology and have been working hard to resolve the issues associated with this type of headphone. This is why they have patented numerous innovations that you can see in their products. For instance, their brand new flexible circuit-based planar magnetic headphones explained winding eliminates the limitations of stamped copper windings to give an improved utilization rate.

The Conductors

Conductors connect the magnets to the diaphragm and are responsible for producing the sound that you hear. These are usually made from a mixture of aluminum and copper. The diaphragm is then wrapped around the central magnetic core. It is then supported by the headphone's frame. The magnetic core may be made from any material, but it is typically Neodymium. The core is the main component of any planar audio driver. It consists of nested layers that form a circular helix of 10-20mm in diameter.

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

The ability of a magnet planar to respond quickly to changes in audio signals is a crucial feature. This makes it easier to reproduce a wide range of frequencies and creates a more detailed and realistic sound. Audiophiles who enjoy music with different instruments and vocals will appreciate this feature.

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

The Magnets

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

Contrary to traditional balanced armature or dynamic drivers that use a stiff diaphragm with a voice coil, 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 results in a more clear and larger soundstage. It is also known for rich bass.

The main disadvantage of planar magnetic headphone drivers is that the large magnets they have require lots of power. This makes them heavier and bulkier than other headphones drivers. As such, many planar magnetic drivers require a separate power amplifier in order to function properly.

The amplifier has to be constructed to match the output power of the planar magnetic driver to give the best listening experience. In addition the amplifier should have a sufficient input impedance to be able to drive the planar magnetic driver at its highest output frequency.

The planar magnetic drive is typically constructed as dipole, which emits equally and in opposite phases in the direction of the speaker's front and back (like ESLs) or a monopole that emits only in the forward-facing direction (more than traditional planars headphones). The most common design of a planar magnetic driver is a bipole that has rotating poles on the south and north. Its shape allows it to be easily fabricated as one piece of metal and creates a strong field at the center of the faceplate.

Planar magnetic drivers are more efficient and have a lower distortion because of their size. They are utilized in high-end headphone systems where sonic precision is important. They are also used in audio equipment that is designed for professional use, such as microphones and loudspeakers. Due to their unique design, they are also suitable for medical imaging as well as other applications that require extremely high precision.

The Seal

To perform well, planar drivers must be sealed very tightly and precisely. A small leakage can cause a significant change in the quality of sound and could cause distortion. It requires a lot of effort to design the ideal seal for the planar driver.

Contrary to many headphone designs, planar magnetic headphones must not have gaps in the enclosure for acoustics. This is because gaps can cause the diaphragm's resonance to be triggered at multiple frequencies at once. This is known as crosstalk, and can cause the entire audio quality to suffer greatly.

The most common type of seal used for planar magnetic headphones is the rubber ring seal. This seal can stop air leaks with great efficiency. It is also very robust and lasts for a long period of time. However it is crucial to keep in mind that this kind of seal may occasionally produce hollow sounds. Therefore, it is important to choose a high-quality rubber seal if planning to use a planar magnetic headphone.

Another alternative to an in-plane magnetic driver is the liquid crystal display (LCD) seal. This is a more advanced type of seal that is designed to stop the formation of gaps. It is also constructed to withstand a substantial amount of pressure. This makes it an excellent option for audiophiles looking for the highest sound quality.

One benefit of LCD headphones is that they provide the most clear and precise sound. This is especially true for high-end models, such as 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 important to remember that planar magnetic headphones can produce a higher sound pressure than dynamic headphones. The way they are constructed is the main reason. Planar magnetic headphones differ from dynamic headphones because they are equipped with two magnets that pull against the diaphragm. This can create a strong force that can produce extremely high frequencies.

Planar magnetic drivers, a recent technology in the headphone market are an innovative product. However, they have already started to change the way people listen to music. In addition to their high-fidelity audio they are also extremely comfortable to wear and easy to adjust.
