How Do Magnet Planar Headphones Work?

If you've not tried a pair of headphones with magnetic drivers with planar design it can be difficult to get your head around how they work. Unlike the voicecoil actuator that drives a stiff cone back and forward the planar magnetic drivers use two flat magnets that are sandwiched between an incredibly thin diaphragm that is printed with conductors.

Diaphragm

Magnet planars are flat pieces made of flexible film, in contrast to traditional dynamic headphone drivers that have cone-shaped or dome-shaped diaphragm. The film has conductors traced on it that interact with magnets placed on either side of the diaphragm. The diaphragm moves and reacts when the magnetic field generated by these magnets is stimulated by the electrical signal running through the wires. This movement creates soundwaves that you then hear.

The diaphragm of the human body is a dome-shaped muscular membrane that divides the thoracic (chest), and abdominal cavities. It is the primary respiratory muscle, and is responsible for inhalation actions, like breathing as well as coughing and sneezing, laughing and crying, vomiting and parturition. The diaphragm plays part in expulsive actions like urination, defecating and pushing out the fetus during the birth.

Due to the ultra-light and thin structure of the diaphragm of a planar magnetic, it is much more responsive to changes in the audio signal than dynamic drivers. These headphones have a a sound that is more delicate and precise than what you get with dynamic drivers.

One of the disadvantages of planar magnet headphones is that, at higher volume, they tend to leak more than their dynamic counterparts. This is due to the movement of the magnet diaphragm of the Planar Magnetic Iem headphones that causes some audio to be pushed away from the listener.

It is not a big deal if you use headphones only in quiet settings or to watch movies. But it can be a nuisance for public or active listening use. There are, however, great options to limit the amount of leakage like the Audeze LCD-4 or HiFiMAN Sundara. Additionally, certain brands such as Wisdom Audio are at the forefront of advancing PMD technology and have been working to solve the issues associated with this type of headphone. They have patented many innovations, which you can see on their products. Their new flex-circuit-based planar wounding overcomes the limitations that stamped copper windings have to provide a higher utilization rate.

The Conductors

Conductors connect the diaphragm to the magnets and are the ones responsible for the sound you hear. They are typically made of a combination copper and aluminum. The diaphragm is then wrapped around the central magnetic core. This is supported by the headphone's frame. The magnetic core is a circular shape magnetic element that can be constructed from any type of material, but it is typically made by using Neodymium. The core is the main element of any planar audio driver. It is made up of nested layers that form a circular helix of 10-20mm in diameter.

Planar magnetic drivers have the advantage of having a 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 just a small portion that is attached to the voice coil. This greater surface area results in lower distortion levels, especially at higher volumes.

Another significant aspect of a magnet planear is its ability to respond quickly to the changes in the audio signal. This allows it to reproduce a broad range of frequencies and creates a more detailed and realistic sound. This is an excellent feature for those who appreciate music that incorporates a variety of instruments and vocals.

The stacked design of planar magnetics reduces part-topart variability which makes them ideal for critical applications that require high reliability. In comparison to wirewound magnetics, these offer improved consistency with lower magnetic field distortion, which is essential for the success of any electronic device.

The Magnets

A magnet is a material with magnetic properties. It can create an attraction or repelling force on certain substances, like nickel and iron. It also attracts and repel electrical conductors. This phenomenon is known as magnetism and can be produced in temporary, permanent or electromagnets. Magnets can be used in a wide range of applications and are used in a variety of devices including electronic devices such as headphones, mobile phones, laptop computers and car audio systems.

Planar magnetic driver technology, unlike traditional dynamic drivers or balanced armatures, which push an extremely rigid and stiff diaphragm using a voice coil to create the sound wavefront, employs a thin and flexible diaphragm. This diaphragm vibrates and creates a flat wavefront, rather than a focused spherical one, which is the norm in most headphones and speaker. This creates a cleaner and spacious soundstage and is well-known for its deep bass.

The biggest drawback of planar magnetic headphone drivers is that the massive magnets they hold require plenty of power. This makes them heavier and bulkier than other headphones drivers. Therefore, a lot of planar magnetic drivers require a dedicated power amplifier in order to function properly.

The amplifier has to be constructed to match the power output of the planar magnetic driver in order to ensure the best listening experience. In addition, the amplifier must be equipped with a sufficient input impedance to be able to drive the planar magnetic driver to its maximum output frequency.

The planar magnetic driver is generally designed to be either a dipole (radiating equally and in a different phase in front and behind the speaker, as ESLs do) or a Monopole (radiating only in the direction of the forward similar to traditional headphones). The most commonly used design of a planar magnetic driver is a bipole, with two poles that alternate on the north and south. Its shape allows it to be easily made into one piece of metal and creates a robust field at the center of the faceplate.

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

The Seal

To be effective, planar drivers must be sealed very well and Planar Magnetic Iem precisely. A small leak can dramatically reduce sound performance and even cause distortion. Therefore, a great deal of effort is put into creating the correct seal for drivers with planar designs.

Unlike many conventional headphone designs that are used, planar magnetic headphones should not have any gaps within the enclosure of the acoustic. This is because gaps cause the diaphragm's resonance to be triggered with multiple frequencies simultaneously. The problem of crosstalk can impact the sound quality.

Rubber rings are the most commonly used type of seal used for headphones that are planar. This seal is able to stop air leaks extremely effectively. It's also extremely durable and can last for a long period of time. It is crucial to remember that this type of seal can occasionally produce an unnatural sound. It is therefore crucial to select a high-quality rubber seal if you're planning to use an earphone with a planar magnetic design.

Another option for a planar magnetic driver is the liquid crystal display (LCD) seal. This is an advanced seal that prevents gaps from forming. It can also be able to withstand pressures of a considerable amount. It is a great option for audiophiles who want high-quality sound quality.

LCD headphones can give a clear and crisp sound. This is particularly relevant for high-end headphones such as the Audeze LCD-4 and HiFiMAN Susvara. However, it's possible to find affordable LCD headphones that provide similar sound quality.

It is also important to remember that a planar magnetic headphone can generate a greater volume of sound than traditional dynamic headphones. The way they are built is the reason. They differ from dynamic headphones because they contain two magnets that pull against the diaphragm. This can create an intense force that could create extremely high frequencies.

Planar magnetic drivers are relatively new technology in the headphone planar magnetic industry. They are beginning to change the way people listen to music. In addition to their superior audio they are also very comfortable to wear and easy to adjust.
