How Do Magnet Planar Headphones Work?
If you’ve not yet tried a pair headphones that use planar magnetic drivers it can be difficult to wrap your head around the way they function. Unlike the voicecoil actuator that drives a stiff cone back and back the planar magnetic drivers use two flat magnets encased in a thin diaphragm printed with conductors.
The Diaphragm
Magnet planars are flat pieces of flexible film, which is different from traditional dynamic headphone drivers that have cone-shaped or dome-shaped diaphragm. The film is made of conductors which 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 magnet Planar move. This motion creates sound waves that can be heard by you.
The diaphragm of the human body is a dome-shaped muscular membranous structure that divides the thoracic (chest) and abdominal cavities. It is the main respiration muscle and is involved in inspiratory actions (exhaling air), such as breathing and coughing, sneezing, laughing, crying vomiting, and even parturition. The diaphragm is also essential in expulsive actions such as the act of urinating and bowel movements and pushing out the fetus during birth.
A planar magnetic diaphragm can be more sensitive to changes in audio signals than dynamic drivers because of its ultra-lightweight and thinness. Planar magnetic headphones produce more delicate, precise sound than dynamic drivers.
One of the disadvantages of planar magnetic headphones is that they can have a bit more leakage than their dynamic counterparts, particularly at higher volume. This is due to the movement of the diaphragm within the magnet headphone causes some of the audio to be pushed further outwards and towards the listener.
It is not a big issue if you use headphones in quiet areas, or to watch movies. But it can be annoying for active listening or public use. There are several alternatives that can help reduce the amount of leakage. They include the Audeze LCD-4 and HiFiMAN Sundara. Wisdom Audio, for example, is at the forefront in the development of PMD technology. They have worked hard to solve the issues associated that arise with this type of headphone. They have developed a number of patents that you can see on their products. Their flex-circuit-based planar-winding technology overcomes the limitations stamped copper windings have to provide a higher utilization factor.
The Conductors
The conductors are what connects the diaphragm and the magnets and are responsible for producing the sound that you hear. They are typically made of a combination of copper and aluminum. These are then wound around an underlying magnetic core which is enclosed by a diaphragm and supported by the frame of the headphone. The magnetic core may be made of any material but is most commonly Neodymium. The core is the main component of any planar magnetic audio driver. It is made up of a series of nested layers of the form of a circular helix having an area of 10-20mm.
Planar magnetic drivers have the advantage of a larger soundstage compared to their dynamic counterparts. This is because when audio signals arrive in the diaphragm, it vibrates across the entire area instead of just the small area attached to the voice coil. This bigger surface area results in lower distortion levels, especially when the volume is higher.
Another important characteristic of a magnet planar is its ability to react quickly to the changes in the audio signal. This enables a wider range of frequencies to be reproduced and more realistic sound. Audiophiles who love music with a variety of instruments and vocals will appreciate this feature.
The stacking design of planar magnetics reduces the variation between parts which makes them ideal for critical applications that require a high reliability. Compared to traditional wirewound magnetics, they offer improved consistency with lower magnetic field distortion, which is vital to the performance of any electronic device.
The Magnets
A magnet is a substance that exhibits magnetic properties. It can create an attraction or repelling force on certain materials, like nickel and iron. It also attracts and repel electrical conductors. This phenomenon is referred to as magnetism. It can be produced by permanent, electromagnets or temporary magnets. Magnets can be utilized in a myriad of applications and are utilised in a variety of devices including electronic devices like headphones, mobile phones, laptop computers and car audio systems.
Unlike traditional balanced armature and dynamic drivers that use an extremely stiff diaphragm using a voice coil, planar magnetic driver technology uses a thin, light, flexible diaphragm to create an unidirectional sound wavefront, rather than the focused spherical wavefront that is common in headphones and speakers. This creates a cleaner and more spacious soundstage, and is recognized for its rich bass.
The biggest drawback to planar magnetic drivers is that they need plenty of power to move the massive magnets within them, which makes them bulkier and heavier than other types of headphone drivers. Many planar magnetic drivers need an amplifier in order to function correctly.
This amplifier must be constructed to match the power output of the planar magnetic driver to ensure the best listening experience. Additionally the amplifier should be equipped with a sufficient input impedance to be able to drive the planar magnetic driver at its maximum output frequency.
The planar magnetic driver is generally constructed to be a dipole (radiating equally and in opposite phase between the front and back of the speaker, as ESLs do) or a Monopole (radiating only in the direction of forward similar to traditional headphones). The most commonly used design of a planar magnetic driver is a bipole with alternating poles on the north and south. Its shape permits it to be made as a single metal piece and creates a very solid field in the center of the faceplate.
Because of their size and efficiency, planar magnetic drivers have a lower distortion factor than other types of headphone drives. They are utilized in premium headphone systems where sonic accuracy matters. They are also found in audio equipment that is professional, such as microphones and speakers. They are also perfect for medical imaging, and other sensitive applications that require high precision.
The Seal
To perform well for optimal performance, planar drivers need to be sealed very tightly and precisely. A tiny leak can cause a significant change in the quality of sound and could cause distortion. It requires a lot of effort to create the right seal for planar driver.
planar headphone magnetic headphones, in contrast to other types of headphones, should not have any gaps within the acoustic enclosure. This is because gaps could cause the diaphragm’s resonance to occur with multiple frequencies simultaneously. This is referred to as crosstalk, and it can cause the audio quality to suffer greatly.
Rubber rings are the most common seals used in planar magnetic headphones. This type of seal is very effective in stopping air leaks. It is also extremely robust and magnet Planar can last for a long time. It is important to keep in mind that this type seal can sometimes create hollow sounds. If you plan to use a planar magnetic headphone, be sure to choose a top-quality seal.
The liquid crystal display (LCD) seal is another option for a magnetic driver. It is a more sophisticated type of seal that is designed to prevent the creation of gaps. It is also designed to withstand a large amount of pressure. It is a great option for audiophiles who want premium sound quality.
LCD headphones can provide clear and precise sound. This is particularly true for high-end models, such as the Audeze LC-4 and HiFiMAN Susvara. But, it’s also possible to find low-cost LCD headphones that offer a similar audio quality.
It is also important to know that a planar magnetic headphone will create a higher volume of sound than traditional dynamic headphones. The way they are built is the main reason. Planar magnetic headphones are different from dynamic headphones in that they contain two magnets that pull against the diaphragm. This can create a strong force that generates high frequencies.
Planar magnetic drivers are a relatively new technology in the world of headphone production. They have started to revolutionize how people listen to music. They have high-quality sound and are comfortable to wear. They are also easy to adjust.
