How Do Magnet Planar Headphones Work? It could be difficult for you to comprehend the workings of planar magnetic drivers if you have never used a pair. Contrary to the voicecoil motor that drives a stiff cone back and forward, planar magnetic drivers employ two flat magnets encased in an incredibly thin diaphragm that is printed with conductors. The Diaphragm Unlike a traditional dynamic headphone driver, which has dome or cone-shaped diaphragms, a magnet planar has a flat piece of flexible film. The film has conductors traced on it that react with magnets placed on either side of the diaphragm. The diaphragm moves and reacts when the magnetic field generated by these magnets gets triggered by the electrical signal running through the wires. This movement creates soundwaves which you can hear. The diaphragm of the human body is a dome-shaped membrane that separates the thoracic (chest) and abdominal cavities. It is the main respiratory muscle and is involved in the process of inspiratory action (exhaling air), such as breathing or coughing, sneezing crying, laughing, vomiting, and parturition. The diaphragm also plays part in expulsive actions like urination or defecating, and pushing the fetus away during the delivery. A planar magnetic diaphragm is much more sensitive to changes in audio signals than dynamic drivers due to its light weight and thinness. Planar magnetic headphones produce more delicate and precise sound than dynamic drivers. One of the downsides of planar magnet headphones is that at higher volumes, they tend to leak more than their dynamic counterparts. This is due to the motion of the diaphragm in the magnet headphone causes some of the audio to be pushed further outwards and towards the listener. This isn't an issue if you use the headphones in quiet environments or while watching films however, it can be a nuisance for listening in public and use. There are, however, great options for reducing the amount of leakage like the Audeze LCD-4 or HiFiMAN Sundara. Additionally, certain brands like Wisdom Audio are at the forefront of the development of PMD technology and have been working to solve the issues that come with this type of headphone. They have developed a number of patents that you can see on their products. For example, their new flex circuit-based planar winding overcomes the limitations of stamped copper windings to give them a better utilization factor. The Conductors Conductors are what connect the magnets to the diaphragm and they're responsible for generating the sound you hear. They are typically made of a mixture of aluminum and copper. The diaphragm is then wrapped around the magnetic core. It is then supported by the headphone's frame. The magnetic core may be constructed from any type of material, but it is typically Neodymium. The core is the central element of any planar audio driver. It is made up of nested layers that form a circular helix of 10-20mm in diameter. One of the main advantages of planar magnetic drivers is that they create an incredibly wide soundstage compared to their dynamic counterparts. This is because when an audio signal is received in the diaphragm, it vibrates across the entire area instead of just the small area attached to the voice coil. This larger surface area also results in lower distortion levels, especially at higher volumes. A magnet planar's ability to quickly react to changes in the audio signals is another important feature. This makes it easier to reproduce a broad range of frequencies and creates a more detailed and realistic sound. Audiophiles who love music with different instruments and vocals will appreciate this feature. The stacking design of planar magnetics reduces part-topart variability which makes them suitable for critical applications that require high reliability. They are more consistent and have less distortion of the magnetic field compared to traditional wirewound magnets. This is essential to the efficiency of electronic devices. The Magnets As its name implies the word magnet refers to one that has magnetic properties. It can draw attention or repel force on certain substances, like nickel and iron. It also attracts and repel certain electrical conductors. This phenomenon is called magnetism. It is produced by permanent, electromagnets or temporary magnets. Magnets are used in many applications, including electronic devices such as headphones, mobile phones and laptop computers. Unlike traditional balanced armature and dynamic drivers, which push a rigid diaphragm that is connected to a voice coil, the planar magnetic driver technology employs a thin, light, flexible diaphragm that vibrates to create an unidirectional sound wavefront instead of the narrow spherical wavefront common in most headphones and speakers. This creates a cleaner and more spacious soundstage, and is recognized for its rich bass. The primary drawback of planar headphone drivers is that the huge magnets they hold require plenty of power. This makes them heavier and bulkier than other headphones drivers. Many planar magnetic drivers need a power amplifier to work effectively. The amplifier has to be constructed to match the output power of the planar magnetic driver to give the best listening experience. The amplifier should also have a high input impedance in order to operate the planar magnet driver to its maximum output. The planar magnetic drive is generally constructed as dipole, which emits equally and in opposite phases in the direction of the speaker's front and back (like ESLs), or a monopole that emits only in the forward direction (more like traditional headphones). The most commonly used design of a planar magnetic driver is a bipole with rotating poles on the south and north. Its shape permits it to be easily fabricated as a single metal piece and creates a strong field at the center of the faceplate. Due to their size and effectiveness, planar magnetic drivers have a lower distortion factor than other types of headphone drives. Visit Webpage are used in high-end headphone systems where sound precision is important. They are also used in audio equipment for professionals like microphones and loudspeakers. They are also perfect for medical imaging and other applications that require high precision. The Seal For planar drivers to function optimally, they must be sealed in a very tight and precise manner. A tiny leak can cause a significant change in the quality of sound and may cause distortion. It requires a lot of effort to design the ideal seal for the planar driver. Contrary to many headphone designs that are used, planar magnetic headphones should not have any gaps in the enclosure for acoustics. This is because gaps cause the diaphragm's resonance to be influenced by different frequencies simultaneously. This is referred to as crosstalk, and can cause the audio quality to suffer greatly. The most common type of seal for planar magnetic headphones is the rubber rings seal. This seal can stop air leaks with great efficiency. It is also very durable and can last for a long period of time. It is crucial to remember that this type of seal can sometimes create hollow sounds. It is therefore crucial to choose a high-quality rubber seal if planning on using an earphone with a planar magnetic design. The liquid crystal display (LCD), seal is another option for a magnetic planar driver. It is a specialized seal designed to prevent gaps from developing. It's also designed to withstand a large amount of pressure. It is an excellent choice for audiophiles who want high-quality sound quality. One benefit of LCD headphones is that they can offer a very clear and detailed sound. This is especially true for high-end headphones, like the Audeze LCD-4 and HiFiMAN Susvara. But, it's also possible to find low-cost LCD headphones that provide similar high-quality sound. It is also important to know that a planar magnetic headphone will create a higher sound pressure than conventional dynamic headphones. The way they are built is the reason. Unlike dynamic headphones, planar magnetic headphones are made up of two magnets that push on the diaphragm. This can create a strong force that generates high frequencies. Planar magnetic drivers are relatively new technology in the world of headphone production. However, they have already begun to change the way listeners enjoy music. In addition to their high-fidelity audio they are also extremely comfortable to wear and easy to adjust.
