Magnetic Planar Speakers – Holographic 3D Imaging and Stunning Clarity Using a thin tensioned diaphragm suspended between 2 arrays of magnets They vibrate to create sound waves. Planar magnetic speakers are famous for their stunning clarity and holographic 3D images. They also offer a wide vertical and horizontal dispersion, low distortion and reasonable costs which makes them suitable for various audio applications. Superior Sound Quality Planar magnetic speakers are renowned for delivering clear, precise sound with minimal distortion. They do this by using a flat diaphragm with an electrically conductive pattern. This is a reaction to the magnetic field created by magnets either on one or both sides of the speaker. This causes the diaphragm to move, creating sound waves that are transmitted via the dipole radiation pattern. This allows the diaphragm to move more evenly, and produce better sound quality than a typical cone or dome driver. Another advantage of planar magnetic drivers is their large dispersion, uniform in size that lets the sound be heard from any position in an area. Ribbon or planar dipole speakers also offer an incredibly spacious and natural soundstage with a few resonances. This provides a unique listening experience that is difficult to replicate with other types of speakers. Planar magnetic speakers have a bigger surface area than cone drivers and are more durable. They are also able to operate at greater volumes without causing distortions or vibrations. They also sound better than other types of speakers, which makes them an excellent option for home theatre and HiFi applications. Planar speakers are more expensive due to their complex design. However, they deliver superior audio quality and are worth the investment. Additionally they have a lower impedance than other kinds of loudspeakers, meaning they are less difficult for amplifiers to drive than conventional drivers. Planar magnetic speakers are an excellent option for home and professional use. However they aren't as popular in IEMs because they require more sophisticated engineering to be able to fit into smaller sizes like headphones and earbuds. Recently however, there has been an increase in the variety of IEMs that feature planar magnetic technology. The Rinko by Seeaudio and the S12 and Z12 from LETSHOUER are just two examples of IEMs that have been shown to provide a great listening experience. Lower Distortion Low distortion is the most sought-after feature of many audiophiles. The distortion is caused in the speaker through a variety of factors, but perhaps the most prevalent cause of distortion is the voice coil inductance. When an alternation voltage is applied to the voice coil of a moving coil driver the voice coil's inductance produces magnetic field which causes the diaphragm to move. The resultant movement, or excursion, is what causes the sound wave to be created, but it also creates unwanted resonances and harmonics that affect the audio quality of the speaker. One of the main advantages of magnetic planar speakers is that they have much less distortion than traditional dynamic drivers. This is because the “voice coil” has more surface area, rather than being squeezed into a tiny space within a huge piece of metal. A well-designed planar magnet speaker can withstand more power than a dynamic driver without the sound of strain. Planar magnetic speakers are also able to reduce distortion by presenting a nearly perfect resistive load to an amplifier in the system. The voice coil is an extremely thin, long wire that acts as an resistor. This makes it easy for the amplifier to drive, and it always sounds its best when driving an asymmetrical magnetic speaker. The high efficiency of magnetic planar speakers implies that they produce little heat, even when playing a lot of music. This is important as a large amount of heat can harm the voice coil, decreasing its lifespan and increasing distortion. This doesn't mean that all planar magnetic single-ended speakers are free of distortion. Because of their close magnet spacing, the magnetic forces can interact and attract each other to a large extent, causing changes to the diaphragm tension as time passes. This problem is made worse by the close proximity between the adjacent rows of magnets. Better Heat Dissipation Many specialization HiFi audio headphone companies have been creating amazing masterpieces in the past few years that use planar magnetic technology. Planar magnetic drivers provide impressive advantages over the common Coiled Dynamics used in the majority of headphones and speakers. One of the major advantages is that the “voice coil” is spread across more of a larger area than a conventional cone speaker that allows it to disperse heat efficiently without becoming too hot. This allows the voice coil to operate more linearly and with less distortion, and also enables an extremely lightweight diaphragm which can be driven to very high levels of excursion. This allows for the planar magnetic speaker to have a remarkably quick transient response, which means that sharp peaks and very tiny details can be reproduced extremely precisely even at extremely high SPLs. This also means that the sound produced is very clean and free from distortion and is not different from the original source material. The planar magnetic speakers has a flat impedance curve, from about 4.2 Ohms in the bass to 3.3 Ohms in the Treble. This makes it a relatively easy load for amplifiers to drive and comparable to the resistive loads used by electronics manufacturers during measurements designed to demonstrate how good their products are. A ribbon/planar diaphragm that is extremely light and compact can move quickly and with little strain. This creates a crystal clear and clean sound with a wide bandwidth and excellent linearity. The ribbon/planar design is also very quiet, which reduces distortion even further. It is also very stable across a broad range of temperatures, allowing the speaker to provide high-quality audio that is consistent throughout long listening sessions and also a large listening space. While the advantages of using a ribbon/planar speakers are numerous, it is important to keep in mind that they are a special type of loudspeaker and not suitable for all applications or for all listeners. A ribbon/planar with a large radiating surface will require a large space to be able to deliver a full-range sound at an acceptable SPL. The majority of these speakers are only sold as tweeters, or as upper mid/high range components in two-way speaker systems. Higher Power Handling Magnetic planar drivers can provide exceptional clarity and detail without distortions that plague traditional cone drivers. They are able to show subtle nuances in your music, and reproduce complex sounds with accuracy. They offer a wide frequency response that allows them to produce a greater range of frequencies accurately. headphones shop create a highly directional sound field, which can be a drawback if you're listening to them in the same room as other people. This is also the reason behind their incredible high-quality image and dynamic range. The sound is like a laser beam emanating directly from the speakers. It can be heard even when you are off-axis. The flat diaphragm in combination with the front of the acoustic wave, provides them with a higher perception of space and depth than cone speakers. They are more likely to have a low noise floor which can make them less distracting in noisy environments. Many audiophiles prefer the natural sound quality of planar magnetic drivers over other technologies. There are still some limitations with the technology. Planar drivers are more difficult to create than cone drivers that are conventional, and they are quite heavy, which makes difficult to install in certain situations. They also require more power to drive, which may limit the maximum output they can achieve. Wisdom Audio is the leader in the research and application of PMD technology. Its products continue to expand the capabilities of this revolutionary technology. The new material that it has patented can withstand temperatures that are much higher than PET that is used to make most planar drivers. The unique design also reduces the effects of diffraction which can occur when sound waves travel through narrow gaps and curves. As a result, its speakers and headphones are known to deliver an exceptionally clear and detailed sound that is free of distortion. They are also more responsive than cone drivers, which could improve their bass response. They're also capable of reproducing high frequencies with amazing accuracy and can also produce powerful, deep bass.
