How Do Magnet Planar Headphones Work?
If you've never tried a pair of headphones with magnetic drivers that planar it might be difficult to get your mind around how they function. Planar magnetic drivers use two flat magnets that sandwich thin diaphragms with conductors. This differs from the voicecoil actuator, which pushes a stiff cone back and forth.
Diaphragm
Magnet
planars headphones are flat pieces made of flexible film, unlike traditional dynamic headphone drivers that have a dome or cone shaped diaphragm. The film has conductors traced on it that interact with magnets that are placed on either side of the diaphragm. When the electrical signal flowing through these wires changes, the magnetic field created 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 muscular membrane that separates thoracic (chest) and abdominal cavities. It is the primary respiratory muscle and is responsible for inspiratory actions, such as breathing coughing and sneezing, laughing and crying as well as vomiting and parturition. The diaphragm is also essential for expulsive actions,

Due to the ultra-light and thin nature of a planar magnetic diaphragm it is 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 drawbacks of planar magnetic headphones is that they tend to have a bit more leakage than their dynamic counterparts, particularly at higher volumes. This is because of the movement of the magnetic 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. But it can be a nuisance for public or active listening use. There are a variety of options to limit the amount of leakage. They include the Audeze LCD-4 and HiFiMAN Sundara. Wisdom Audio, for example, is a pioneer in developing PMD technology. They have put in a lot of effort to solve the issues associated with this kind of headphone. This is why they have patents on several innovations that you can observe in their products. Their flex-circuit-based planar-winding technology overcomes the limitations stamped copper windings face to provide a higher utilization.
The Conductors
The conductors connect the diaphragm with the magnets and are responsible for the sound you hear. They are typically made from a mix of aluminum and copper. These are then wound 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 circular form of magnetic element and can be made from any type of material, but it is most commonly produced with Neodymium. The core is the main element of any planar sound driver. It is made up of nested layers and a circular helix of 10-20mm in diameter.
Planar magnetic drivers have the benefit of a larger soundstage than their dynamic counterparts. This is due to the fact that the entire diaphragm is vibrating 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, particularly at higher volumes.
Another significant characteristic of a magnet Planar (

The stacked design of planar magnetics reduces part-topart variability which makes them ideal for critical applications that require a high reliability. They offer better consistency and lower distortion in the magnetic field when compared to traditional wirewound magnets. This is essential for the efficiency of electronic devices.
The Magnets
A magnet is a substance with magnetic properties. It can exert an attraction or repelling force on certain substances, such as iron and nickel. It can also draw or repel electrical conductors. This phenomenon is known as magnetism. It can be created through electromagnets, permanent, or temporary magnets. Magnets can be used in a variety of applications and are utilised in a variety of electronic devices like headphones, mobile phones, laptop computers and car audio systems.
Planar magnetic driver technology, unlike traditional balanced armature or dynamic drivers, which push a stiff, rigid diaphragm using the voice coil to produce the sound wavefront, employs an extremely thin and flexible diaphragm. The diaphragm is vibrating and creates a flat wavefront, instead of a spherical focused one, as is typical in the majority of headphones and speakers. This produces a much larger and more expansive soundstage, and is well-known for its deep bass.
The main drawback of planar magnetic drivers is that they need plenty of power to move the large magnets inside them, which makes them bulkier and heavier than other kinds of headphone drivers. Therefore, a lot of planar magnetic drivers require a dedicated power amplifier to function correctly.
This amplifier must be designed to match the power output of the planar magnetic driver to give the best listening experience. Additionally the amplifier should have a sufficient input impedance 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 of and behind the speaker, as ESLs do) or a monopole (radiating only in the direction of the forward and more like traditional headphones). The most common design is a bi-pole with one north and one south pole. Its shape makes it easy to build as one piece of metal and is very efficient at producing a strong field in the center of the faceplate.
Planar magnetic drivers are more efficient and have a lower distortion due to their dimensions. As such, they are often employed in headphones with high-end features in which sonic precision is essential. You can also find them in audio equipment that is professional, such as speakers and microphones. Due to their unique construction, they are also suitable for medical imaging as well as other applications that require extremely high precision.
The Seal
To be effective for optimal performance, planar drivers need to be sealed extremely securely and precisely. A small leak can greatly reduce sound performance and even cause distortion. So, a lot of work is required to create the proper 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 will cause the diaphragm's resonance to be influenced by different frequencies simultaneously. The problem of crosstalk can impact the sound quality.
Rubber ring seals are the most common seals used in headphones that are planar. This seal can stop air leaks with great efficiency. It is also very robust and lasts for a long time. It is crucial to remember that this type of seal can sometimes produce hollow sounds. If you are planning to use a planar magnet headphone,

The liquid crystal display (LCD), seal is a different option for a magnetic planar driver. This is a higher-end type of seal designed to prevent the creation of gaps. It also can withstand a lot of pressure. It is a great option for audiophiles seeking top-quality sound quality.
LCD headphones can produce a clear and precise sound.
