How Do Magnet Planar Headphones Work?

If you’ve never tried a pair of headphones that use planar magnetic drivers it can be difficult to get your mind around how they work. Planar magnetic drivers use two flat magnets that are sandwiched between a thin diaphragm and conductors. This is different from the voicecoil actuator which pushes a stiff cone back and forward.

Diaphragm

Magnet planars are flat pieces made of flexible film, unlike traditional dynamic headphone drivers, which have cone or dome-shaped diaphragm. The film has conductors etched on it, which react with magnets that are placed on either side of the diaphragm. When the electrical signal passing through these wires changes the magnetic field generated by the magnets causes the diaphragm react and move. This movement creates soundwaves which you can hear.

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

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

One of the drawbacks of planar magnetic headphones is that, at higher volume, they can leak more than their dynamic counterparts. This is because of the movement of the magnet diaphragm of the planar headphones which causes some audio to be pushed towards the listener.

It’s not a big deal if you use headphones in quiet areas or to watch films. However, it can be a nuisance for public or active listening usage. There are, however, great options for reducing the amount of leakage, like the Audeze LCD-4 or HiFiMAN Sundara. Wisdom Audio, for example, is a pioneer in the development of PMD technology. They have worked hard to solve the issues associated with this type of headphone. This is the reason they have patented various innovations that you observe in their products. Their new flex-circuit-based planar wounding overcomes the limitations stamped copper windings face to provide a higher utilization.

The Conductors

Conductors are what connect the magnets to the diaphragm and they’re responsible for generating the sound you hear. They are typically made of a combination copper and aluminum. They are then wrapped around a central magnetic core, which is enclosed by the diaphragm, and is held by the frame of the headphone. The magnetic core is a cylindrical shaped magnetic element and can be made of any material, but it is most commonly produced with Neodymium. The core is the main component of any planar magnetic audio driver. It is made up of several nested layers of a circular helix with an area of 10-20mm.

Planar magnetic drivers have the advantage of a larger 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 attached to the voice coil. This larger surface area also results in lower distortion levels, particularly at higher volumes.

A magnet planar’s ability to respond quickly to changes in audio signals is a crucial feature. This allows it to reproduce a wide range of frequencies, and also produces more realistic and detailed sound. This is an excellent feature for those who appreciate music that incorporates a variety of instruments and vocals.

The stacking design of planar magnetics reduces part-topart variability which makes them suitable for critical applications that require a high reliability. As compared to wirewound magnetics, these offer improved consistency with lower magnetic field distortion, which is vital for the success of any electronic device.

The Magnets

Like its name suggests it is one that has magnetic properties. It can cause a repulsive or attractive force on certain materials, such as nickel, iron cobalt and a few steels. It also attracts and repel electrical conductors. This phenomenon is known as magnetism. It can be produced in temporary, permanent or electromagnets. Magnets are used in many applications, including electronic devices such as mobile phones, headphones, and laptop computers.

Planar magnetic driver technology, unlike traditional dynamic drivers or balanced armatures which use a rigid, stiff diaphragm using the voice coil to produce the sound wavefront, uses an extremely thin and flexible diaphragm. This diaphragm vibrates and creates a flat wavefront, rather than a focused spherical one, as is typical in most headphones and speaker. This creates a larger and cleaner soundstage, and is also recognized for its deep bass.

The biggest disadvantage of closed-back planar magnetic headphones magnetic drivers is that they require quite a bit of power to move the massive magnets within them making them more bulky and heavier than other kinds of headphone drivers. Therefore, a lot of planar magnetic drivers require a special power amplifier to function correctly.

The amplifier has to be designed to match the output power of the planar magnetic driver to give the best listening experience. The amplifier must 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 drive is typically designed as either dipole, which emits equally and in opposing phases in front and behind the speaker (like ESLs) or a monopole that radiates only in the forward-facing direction (more than traditional headphones). The most common model is a bipole, with one north and one south pole. Its shape makes it simple to fabricate as one piece of metal and is very efficient at creating a strong field in the center of the faceplate.

Planar magnetic drivers are more efficient and have a lower distortion due to their size. They are used in high-end headphone systems where sonic accuracy matters. They are also used in audio equipment that is designed for professional use, such as microphones and loudspeakers. Because of their unique construction they are also ideal for medical imaging and other sensitive applications that require a high degree of precision.

The Seal

To ensure that planar drivers function effectively, they must be sealed in a very exact and precise way. A small leakage can cause a significant change in the quality of sound and may cause distortion. So, a lot of effort is put into creating the correct seal for planar drivers.

In contrast to the majority of conventional headphone designs the planar magnetic headphones should not have any gaps within the enclosure for acoustics. This is because gaps can cause the diaphragm’s resonance with different frequencies simultaneously. Crosstalk is a problem that can affect the sound quality.

The most commonly used seal used for planar magnetic headphones is the rubber rings seal. This seal is able to stop air leaks extremely effectively. It is also extremely robust and lasts for an extended period of time. However it is crucial to keep in mind that this type of seal can sometimes create hollow sounds. This is why it is crucial to choose a high-quality rubber seal if planning to use the planar magnetic headphone.

Another alternative to an in-plane magnetic driver is the liquid crystal display (LCD) seal. This is a higher-end kind of seal that has been designed to stop the formation of gaps. It can also stand up to pressures of a great deal. It is an excellent choice for audiophiles looking for top-quality sound quality.

LCD headphones can give a clear and crisp sound. This is especially applicable to high-end models like the Audeze LCD-4 and HiFiMAN Susvara. It is possible to find LCD headphones that have the same sound quality for a lesser price.

It is also important to remember that the planar magnetic headphone may generate a greater sound pressure than standard dynamic headphones. This is because of the way they are constructed. In contrast to dynamic headphones, planar magnetic headphones are made up of two magnets that push on the diaphragm. This creates an enormous force that can produce very high frequencies.

Planar magnetic drivers, a relatively new technology on the world of headphones are a revolutionary product. They have begun to change the way people listen to music. In addition to their high-quality sound these headphones are very comfortable to wear and magnet Planar easy to adjust.
