Magnetic Planar Speakers - Holographic 3D Imaging and Stunning Clarity
They create sound waves through vibrating a thin diaphragm that is suspended between two arrays of magnets. Planar magnetic speakers are known for their holographic 3D images and breathtaking clarity.
They are also ideal for a variety of audio applications because of their low distortion, wide horizontal and vertical dispersion and low costs.
Superior Sound Quality
When it is about high-performance audio, planar magnetic speakers are famous for their ability to produce clear, detailed sound with low distortion. They do this by employing a flat diaphragm with an electrically conductive pattern. This reacts to the magnetic field created by magnets on the one or both sides of the speaker. The diaphragm is then able to move, producing sounds waves that are transmitted by a monopole or dipole radiation pattern. This allows the diaphragm to vibrate more evenly, and create superior sound quality than a standard dome or cone driver.
Planar magnetic drivers also have the benefit of a wide, uniform sound dispersion. This allows for the sound to be heard from any place within the room. Additionally, planar ribbon or dipole speakers have an unnatural and expansive soundstage, with minimal resonances. This creates an immersive listening experience that brings music to life in a manner that is hard to replicate with other types of speakers.
Because they cover a large surface area they are also more durable than conventional cone drivers and can operate at higher volumes without causing excessive vibrations or distortion. They also have less mechanical noise than other types of drivers, making them an excellent option for home theater and HiFi applications.
Due to their intricate design, planar speakers can be more expensive than other kinds of loudspeakers, however they provide superior sound quality that is worth the cost. Planar speakers also have a lower impedance when compared to other types of loudspeakers. This makes them more suitable to drive amplifiers.
Planar magnetic speakers are an excellent option for both professional and home use. However they aren't as well-liked in IEMs because they require more intricate engineering to be able to fit into smaller form factors like headphones and earbuds. Recently, however there is a surge in the number of IEMs available with planar magnetic technology. This includes the Rinko by Seeaudio and the S12 & Z12 by LETSHOUER, which have proved to offer an outstanding listenable experience.
Lower Distortion
For a lot of audiophiles, the most sought-after characteristic of a speaker or headphone is the low distortion. Voice coil inductance is the most common cause of distortion in speakers. When an alternation voltage is applied to the voice coil of a moving coil driver the inductance of the voice coil creates a magnetic fields that cause the diaphragm to move. The resultant movement, also known as excursion is the reason for the sound wave to be produced, but it also creates unwanted resonances and harmonics that reduce the sound quality of the speaker.
Magnetic planar speakers have a lower distortion level than traditional dynamic drivers. This is due to the fact that the "voice coil" is spread across an extensive surface instead of being squeezed into a small gap inside a huge chunk of metal. A well-designed planar magnet speaker can handle more power than a dynamic driver without audible strain.
Another way in which planar magnetic speakers minimize distortion is by presenting an almost perfect resistive load to the amplifier inside the system. This is due to the fact that the voice coil is a long, thin wire that behaves just like a simple resistor. This makes the amplifier simple to drive and will sound the best when driven by the magnetic planar speaker.
The high efficiency of these speakers is that they produce little heat, even when playing a lot of music. This is important, as much heat can harm the voice coil and reduce its lifespan.
However, this does not mean that all planar single-ended speakers are free of distortion. Because of their proximity to the magnet spacing, magnetic forces can interact with one other and attract one another to a considerable extent, causing changes to the diaphragm's tension as time passes. This issue is made more difficult due to the close proximity between adjacent rows of magnets.
Better Heat Dissipation
Many specialization HiFi audio headphone companies have been creating amazing masterpieces in recent years using planar magnetic technology. Planar magnetic drivers provide impressive advantages over the common coiled dynamics used in most headphones and speakers.
The "voice coil" can dissipate the heat more effectively than a cone speaker as it is spread over more of a surface. This helps the voice coil operate more efficiently and
magnetic planar speakers with less distortion, and also enables an extremely lightweight diaphragm which can be driven to extremely high levels of excursion.
This enables the planar magnet speaker to have an exceptionally rapid transient response. Sharp peaks and tiny details can therefore be reproduced with great accuracy even at very high SPLs. The sound produced is also extremely clear and free of distortion, and indistinguishable to the original source material.
The planar magnetic speaker also has a very flat impedance curve, from about 4.2 ohms in the bass, to 3.3 ohms in the Treble. This makes it an easy load for amplifiers to drive, and comparable to resistive loads that electronics manufacturers use in their tests to show how great their products are.
Another advantage is that the ribbon/planar diaphragm is extremely light, which enables it to move extremely quickly and easily with less strain. This creates a crystal clear and clear sound, with a wide range of frequencies and excellent linearity.
The ribbon/planar is also extremely quiet, which helps reduce distortion. It also remains stable across a broad range in temperatures which allows the speaker to produce consistent audio quality over long periods of listening and also a large listening space.
While the advantages of using a ribbon/planar speakers are numerous, it is crucial to remember that they are a specialized type of loudspeaker and not appropriate for every application or for all listeners. A large ribbon/planar radiating surface will require a large room in order to produce the full range of sound at an adequate SPL. Because of this, the majority of such speakers are sold as tweeters or as an upper mid/high range part of a two-way system.
Higher Power Handling
Magnetic planar drivers provide exceptional clarity and detail without distortions that plague traditional cone drivers. They can detect subtle details and reproduce complex sounds precisely. They also have a broad frequency response, which means they can produce a greater range of frequencies, with greater accuracy.
Planar speakers create a highly directional sound field, which can be a problem when you're listening in an area with other people. This is also the reason behind their amazing dynamic range and pristine image. The sound
what is a planar headphone like a laser beam, emanating directly from the speakers. It can be heard when you are off-axis.
The flat diaphragm and the acoustic wavefront provide them with an enhanced sense of depth and spaciousness than conventional cone speakers. They also have an acoustic wavefront that is less noisy which makes them less distracting in noisy environments. Planar magnetic drivers are highly regarded by a lot of audiophiles due to their natural sound quality.
However, there are some limitations to the technology. Planar drivers are more difficult to manufacture and heavier than cone drivers. They can also be difficult to mount in certain conditions.
