How Do Magnet Planar Headphones Work?

It might be difficult to understand the workings of planar magnetic drivers if you have never used the two. Planar magnetic drivers employ two flat magnets which are sandwiched in thin diaphragms with conductors. This differs from the voicecoil actuator which drives a stiff cone back and back and forth.

Diaphragm

Unlike a traditional dynamic headphone driver that has a cone or dome shaped diaphragm, a magnet planar has a flat piece of flexible film. The film is etched with conductors that react to magnets on across the membrane. When the electrical signal passing through these wires changes the magnetic field generated by the magnets causes the diaphragm react and move. The movement produces sound waves that you then hear.

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

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

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

It's not a huge deal if you use headphones in quiet areas or to watch films. But it can be a nuisance for public or active listening usage. There are, however, very good options available for reducing the amount of leakage such as the Audeze LCD-4 or HiFiMAN Sundara. In addition, some brands such as Wisdom Audio are at the forefront of developing PMD technology and have been working hard to address the issues associated from this kind of headphone. This is why they have patented numerous innovations that you can observe in their products. For example, their new flexible circuit-based planar winding eliminates the limitations of stamped copper windings to give an improved utilization rate.

The Conductors

Conductors connect the diaphragm to the magnets and are responsible for the sound you hear. They are usually made of a mixture of aluminum and copper. These are then wound around the central magnetic core which is enclosed by a diaphragm and is supported by the frame of the headphone. The magnetic core is a cylindrical shape magnetic element that can be constructed from any material, but it is usually made by using Neodymium. The core is the primary element of any planar sound driver. It is comprised of nested layers and an elongated helix that is 10-20mm in diameter.

Planar magnetic drivers have the advantage of having a wider soundstage compared to their more dynamic counterparts. This is because the entire diaphragm vibrates when an audio signal is received, instead of a tiny portion that is attached to the voice coil. This bigger surface area results in lower distortion levels, especially at higher volumes.

The ability of a magnet planar to quickly react to changes in audio signals is another important feature. This makes it easier to reproduce a wide range of frequencies, and also produces a more detailed and realistic sound. This is a fantastic feature for audiophiles who love music that incorporates a variety of instruments and vocals.

Additionally, the stacked structure of a planar magnetic decreases part-to-part variation and is perfect for mission critical applications that require high-reliability. In comparison to wirewound magnetics, they offer better consistency and lower magnetic field distortion, which is crucial to the performance of any electronic device.

The Magnets

A magnet is a material that has magnetic properties. It can exert an attractive or repulsive force on certain materials such as nickel, iron cobalt, and some steels. It also can draw or repel certain electrical conductors. This phenomenon is known as magnetism. It is produced in permanent, temporary or electromagnets. Magnets are used in a variety of applications and can be found in many different types of devices including electronic devices like headphones, laptop computers, mobile phones and car audio systems.

In contrast to traditional balanced armature and dynamic drivers, which push a rigid diaphragm that is connected to the voice coil, planar magnetic driver technology uses a thin, Closed-back planar magnetic headphones light and flexible diaphragm that vibrates to create an unidirectional sound wavefront, instead of the narrow spherical wavefront found in many headphones and speakers. This creates a much cleaner and larger soundstage. It is also well-known for its deep bass.

The primary drawback to planar magnetic drivers is that they need quite a bit of power to move the large magnets inside them making them more bulky and heavier than other kinds of headphone drivers. Many planar magnetic drivers need an amplifier to function properly.

The amplifier should be designed to match the power output of the planar magnetic driver to give the best planar headphones listening experience. The amplifier should also have an extremely high input impedance in order to be able to drive the planar magnetic driver to its maximum output.

The planar magnetic speakers magnetic driver is generally designed to be either 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 forward similar to traditional headphones). The most popular design is a bi-pole with one north and one south pole. Its shape makes it simple to create as a single piece of steel and is extremely efficient in creating a strong field in the center of the faceplate.

Due to their size and effectiveness due to their size and efficiency, closed-back planar magnetic Headphones magnetic drivers have a lower distortion than other types of headphone drivers. As such, they are commonly used in high-end headphones where sonic accuracy is important. They can also be found in audio equipment that is designed for professional use, such as microphones and loudspeakers. Due to their unique design they are also ideal for medical imaging and other sensitive applications that require extremely high precision.

The Seal

To ensure that planar drivers function well they must be sealed in a very exact and precise way. A tiny leak can be a major impact on the quality of sound and could cause distortion. It requires a lot of effort to design the ideal seal for planar driver.

Planar magnetic headphones, Closed-Back Planar Magnetic Headphones in contrast to other types of headphones, should not have gaps within the enclosure of the acoustic. This is because gaps cause the diaphragm to resonate with different frequencies at the same time. The problem of crosstalk can affect the sound quality.

Rubber rings are the most popular seals used in planar magnetic headphones. This seal is able to stop air leaks very effectively. It is also very robust and can last for a long time. However, it is important to be aware that this kind of seal may sometimes produce an unnatural sound. If you plan to use a planar magnetic headphone, it's important to choose a seal that is of high-quality.

Another alternative for a planar magnetic driver is the liquid crystal display (LCD) seal. It is a more sophisticated type of seal designed to prevent the creation of gaps. It also can 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 provide clear and precise sound. This is especially true for high-end headphones, like the Audeze LCD-4 or 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 produce a much higher sound pressure than standard dynamic headphones. This is due to the way they are made. Planar magnetic headphones differ from dynamic headphones in that they are equipped with two magnets that pull against the diaphragm. This creates an enormous force that can generate extremely high frequencies.

Planar magnetic drivers, a relatively new technology on the world of headphones are an innovative product. They have started to revolutionize the way people listen to music. In addition to their superior audio, these headphones are also very comfortable to wear and are easy to adjust.
