How Do magnet planar, see page, Headphones Work?
If you’ve never tried a pair of headphones that use planar magnetic drivers it can be difficult to wrap your mind around how they work. Planar magnetic drivers employ two flat magnets that are sandwiched between a thin diaphragm with conductors. This is different from the voicecoil actuator, which drives a stiff cone back and forward.
Diaphragm
Magnet planars are flat pieces of flexible film, which is different from traditional dynamic headphone drivers with a dome or cone shaped diaphragm. The film is coated with conductors that react to magnets that are placed on across the membrane. The diaphragm is able to react and move when the magnetic field created by these magnets is stimulated by the electrical signal running through the wires. This causes soundwaves that you can then hear.
The diaphragm of the human body is a dome-shaped membranous muscular structure that separates the thoracic (chest) and abdominal cavities. It is the primary respiratory muscle and is involved in the process of inspiratory action (exhaling air) like breathing, sneezing, coughing, crying, laughing vomiting, and parturition. The diaphragm is also a role in expulsive movements like urinating or defecating, and pushing the fetus away during birth.
Due to the ultra-light and thin structure of a planar diaphragm it is more sensitive to changes in the audio signal than dynamic drivers. This gives planar magnetic headphones sound that is more delicate and precise than the sound you get from dynamic drivers.
One of the disadvantages of planar magnetic headphones is that at higher volume, they tend to leak more than their dynamic counterparts. This is because the movement of the diaphragm within a magnet planar headphone causes a portion of the audio to be pushed outwards and towards the listener.
It’s not a big issue if you are using headphones in quiet areas, or to watch movies. But it can be a nuisance when you are listening to music or in public use. There are a few options to minimize the amount of leakage. These include the Audeze LCD-4 and HiFiMAN Sundara. Wisdom Audio, for example is a leader in developing PMD technology. They have worked hard to resolve issues with this kind of headphone. This is why they have patents on various innovations that you see in their products. Their new flex-circuit-based planar winding overcomes the limitations that stamped copper windings have to offer a higher utilization rate.
The Conductors
Conductors are what connect the magnets to the diaphragm and they are the ones responsible for creating the sound that you hear. They are typically made from a mixture of aluminum and copper. These are then wound around a central magnetic core, which is surrounded by the diaphragm and supported by the frame of the headphone. The magnetic core is a circular form of magnetic element and can be made of any material, however it is typically made with Neodymium. The core is the main element of any planar sound driver. It is comprised of nested layers and an helix circular in size, ranging from 10-20mm in diameter.
A key advantage of planar magnetic drivers is that they produce a much wider soundstage than their dynamic counterparts. This is because the entire diaphragm vibrates whenever an audio signal is received, instead of a tiny area that is connected to the voice coil. This greater surface area results in lower distortion levels, particularly at higher volumes.
Another important feature of a magnet planar is its ability to respond quickly to changes in the audio signal. This makes it easier to reproduce a wide range of frequencies and creates an even more realistic and detailed sound. This is a fantastic feature for those who appreciate music that includes a variety of instruments and vocals.
Furthermore, the stacked design of a planar magnet reduces the variability of parts and is suitable for mission critical applications that require high-reliability. They offer better consistency and lower distortion in the magnetic field when as compared to wirewound magnetics. This is essential for the efficiency of electronic devices.
The Magnets
A magnet is a substance that has magnetic properties. It can exert an attractive or repulsive force on certain materials such as iron, nickel, cobalt and a few steels. It can also draw or repel certain electrical conductors. This phenomenon is referred to as magnetism. It can be created by electromagnets, permanent or temporary magnets. Magnets can be used in a variety of applications and are utilised in a variety of electronic devices such as headphones laptop computers, mobile phones and car audio systems.
Planar magnetic driver technology, in contrast to traditional dynamic or balanced armature drivers, which push an extremely rigid and stiff diaphragm with an electric voice coil to create the sound wavefront, employs a thin and flexible diaphragm. This diaphragm vibrates and creates a flat wavefront instead of a spherical focused one, which is the norm in the majority of headphones and speakers. This results in a more clear and larger soundstage. It is also known for rich bass.
The primary drawback to planar magnetic planar speakers drivers is that they require plenty of power to move the large magnets inside, which makes them bulkier and heavier than other types of headphone drivers. Many planar magnetic drivers need a power amplifier to work correctly.
This amplifier must be constructed to match the power output of the planar magnetic driver to give the best listening experience. The amplifier should also have an extremely high input impedance in order to be able to drive the planar magnetic driver at its maximum output.
The planar magnetic drive is typically constructed as dipole, which emits equally and in opposing phases in the direction of the speaker’s front and back (like ESLs) or a monopole that emits only in the forward direction (more similar to traditional headphones). The most common design of a planar magnetic driver is a bipole that has alternating poles on the north and south. Its shape lets it be easily made into one piece of metal and produces a very strong field at the center of the faceplate.
Planar magnetic drivers are more efficient and have a lower distortion factor because of their size. This is why they are frequently employed in headphones with high-end features where sound quality is crucial. They are also found in audio equipment that is professional, such as microphones and speakers. Due to their unique construction they are also suited for medical imaging and other sensitive applications that require extremely high precision.
The Seal
For planar drivers to function effectively, magnet planar they must be sealed in a tight and precise manner. A tiny leak can be a major impact on the sound quality and even cause distortion. So, a lot of effort is put into creating the proper seal for planar drivers.
In contrast to the majority of conventional headphone designs that are used, planar magnetic headphones should not have gaps in the enclosure for acoustics. This is because gaps cause the diaphragm’s resonance to be influenced by multiple frequencies simultaneously. This is referred to as crosstalk, and it can cause the entire sound quality to be affected.
The most commonly used seal for planar magnetic headphones is the rubber rings seal. This seal is very effective at preventing air leaks. It is also extremely durable and can last for a long period of time. However it is essential to remember that this type of seal can sometimes produce hollow sounds. If you’re planning to use a planar magnetic headphone, be sure to select a high-quality seal.
The liquid crystal display (LCD), seal is another option for a magnetic planar driver. This is a high-tech seal that is designed to stop gaps from creating. It can also be able to withstand pressures of a considerable amount. This makes it an excellent choice for audiophiles who are seeking the best sound quality.
One benefit of LCD headphones is that they can provide an extremely clear and detailed sound. This is particularly the case for headphones that are high-end, such as the Audeze LCD-4 or HiFiMAN Susvara. However, it is also possible to find affordable LCD headphones that have similar sound quality.
It is also important to know that a planar magnetic headphone will generate a greater volume of sound than traditional dynamic headphones. This is due to the way they are made. Planar magnetic headphones differ from dynamic headphones because they are equipped with two magnets that pull against the diaphragm. This can create an intense force that could generate extremely high frequencies.
Planar magnetic drivers are a relatively new technology in the world of headphone production. They have begun to revolutionize how people listen to music. In addition to their superior audio they are also very comfortable to wear and are easy to adjust.
