How Do Magnet Planar Headphones Work?

If you've not yet tried a pair headphones that utilize magnetic drivers with planar design it can be difficult to get your mind around how they function. Planar magnetic drivers use two flat magnets that are sandwiched between a thin diaphragm and conductors. This is different from the voicecoil motor, which drives a stiff cone back and back and forth.

The Diaphragm

In contrast to a traditional dynamic headphone driver that has dome or cone shaped diaphragms, a magnet planar has a flat piece of flexible film. The film is made of conductors which react to magnets placed either side of the membrane. The diaphragm reacts and moves when the magnetic field generated by these magnets gets triggered by the electrical signal running 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 divides the thoracic (chest), and abdominal cavities. It is the primary respiration muscle and is involved in the process of inspiratory action (exhaling air), such as breathing, sneezing, coughing, crying, laughing vomiting, Headphone Planar Magnetic and parturition. The diaphragm plays an important role in expulsive movements like urinating, defecating and pushing the fetus away during birth.

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

One of the drawbacks of planar magnetic headphones is that they tend to have a little more leakage than their dynamic counterparts, particularly at higher volumes. This is due to the movement of the diaphragm in the magnet headphone causes a portion of the audio to be pushed outwards and toward the listener.

This is not an issue if you listen to music in quiet environments or when watching movies however, it can be a problem for public listening and active usage. There are, however, great options to reduce the amount of leakage like the Audeze LCD-4 or HiFiMAN Sundara. Additionally, certain brands such as Wisdom Audio are at the forefront of the development of PMD technology and have been working to solve the issues that come from this kind of headphone. They have patented many innovations, which you can see on their products. Their new flex-circuit-based planar winding overcomes the limitations stamped copper windings face to provide a higher utilization rate.

The Conductors

Conductors link the diaphragm to the magnets and are the ones responsible for the sound you hear. These are usually made from an amalgamation of aluminum and copper. These are then wound around an underlying magnetic core which is enclosed by a diaphragm, and is held by the frame of the headphone. The magnetic core may be made from any material but is most commonly Neodymium. The core is the central element of any planar sound driver. It consists of nested layers with a circular helix of 10-20mm in diameter.

The main benefit 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 when an audio signal is received instead of a tiny area that is connected to the voice coil. The larger surface area results in lower distortion levels, particularly at higher volume.

Another significant feature of a magnet planar is its ability to respond quickly to the changes in the audio signal. This allows for a wider spectrum of frequencies to be reproduced, as well as a more authentic sound. Audiophiles who enjoy music with a variety of instruments and vocals will appreciate this feature.

The stacked design of planar magnetics reduces part-topart variability, making them ideal for critical applications that require a high reliability. They offer better consistency and less distortion of the magnetic field in comparison to wirewound magnets. This is essential for the success of electronic devices.

The Magnets

Like its name suggests, a magnet is one that has magnetic properties. It can draw attention or repel force on certain substances, such as iron and nickel. It also has the ability to attract or repel certain electrical conductors. This phenomenon is known as magnetism. It can be created in permanent, temporary or electromagnets. Magnets are used in a myriad of applications and are utilised in many different types of devices, including electronic devices such as headphones mobile phones, laptop computers and car audio systems.

Planar magnetic driver technology, in contrast to traditional dynamic or balanced armature drivers, which push a rigid, stiff diaphragm with an electric voice coil to create the sound wavefront, uses a thin and flexible diaphragm. The diaphragm is vibrating and creates a flat wavefront rather than a focused spherical one, as is typical in the majority of headphones and speakers. This results in a more spacious and cleaner soundstage and is recognized for its deep bass.

The biggest drawback of planar magnetic drivers is that the large magnets they contain require plenty of power. This makes them heavier and bulkier than other types of headphone drivers. As such, many planar magnetic drivers require a special power amplifier to function correctly.

This amplifier must be designed to match the output power of the planar magnetic driver in order to give the best planar magnetic iem listening experience. The amplifier should also have an extremely high input impedance to allow it to operate the planar magnet driver at its maximum output.

The planar magnetic driver is generally constructed to be dipole (radiating equally and in a different phase in front and behind the speaker, similar to ESLs) or a monopole (radiating only in the forward direction similar to traditional headphones). The most common model is a bipole, with one north and one south pole. Its shape makes it simple to build as one piece of metal and is very effective in producing a strong field in the center of the faceplate.

Due to their size and effectiveness, planar magnetic drivers have a lower distortion than other types of headphone drivers. This is why they are commonly employed in headphones with high-end features in which sonic precision is essential. They can also be found in audio equipment for professionals such as microphones and loudspeakers. Due to their unique construction, they are also suitable for medical imaging and other sensitive applications that require extremely high precision.

The Seal

To ensure that planar drivers function effectively, they must be sealed in a very tight and precise manner. A small leak could cause a significant change in the quality of sound and could cause distortion. It requires a lot of effort to make the perfect seal for a 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's resonance with multiple frequencies simultaneously. Crosstalk is a problem that can affect the sound quality.

Rubber ring seals are the most common type of seal used in headphones that are planar. This type of seal prevents air leaks with great efficiency. It's also extremely durable and can last for a long time. It is crucial to remember that this type seal can occasionally produce an unnatural sound. If you are planning to use a planar magnetic Headphone planar magnetic, it's important to choose a seal that is of high-quality.

Another alternative for an in-plane magnetic driver is the liquid crystal display (LCD) seal. This is a more advanced 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.

LCD headphones can provide clear and precise sound. This is especially true for high-end models, like the Audeze LCD-4 and HiFiMAN Susvara. It is possible to find LCD headphones with the same sound quality for a lesser price.

It is important to note that planar magnetic headphones can produce a higher sound pressure than dynamic headphones. This is because of the way they are made. Contrary to dynamic headphones magnetic headphones have two magnets that push on the diaphragm. This creates a powerful force that generates high frequencies.

Planar best magnetic planar headphones drivers are a relatively new technology used in the headphone industry. However, they have already started to change the way listeners enjoy music. These headphones offer high-quality sound and are comfortable to wear. They are also simple to adjust.
