magnetic planar – bestone-korea.com explained in a blog post – Speakers – Holographic 3D Imaging and Stunning Clarity
Using a thin tensioned diaphragm suspended between 2 arrays of magnets, they vibrate to produce sound waves. Planar magnetic speakers are renowned for their incredible clarity and holographic 3D images.
They are also ideal for a wide range of audio applications because of their low distortion, broad horizontal and vertical dispersion and affordable costs.
Superior Sound Quality
Planar magnetic speakers are renowned for delivering clear, precise sound with minimal distortion. They accomplish this by using an elongated diaphragm that has a conductive pattern on it. This reacts to the magnetic field produced by magnets either on one or both sides of a speaker. The diaphragm moves creating sound waves that can be transmitted via a dipole- or monopole-radiation pattern. This causes the diaphragm to vibrate more evenly and produce superior sound quality compared to a typical dome or cone driver.
Planar magnetic drivers also have the benefit of a broad and uniform sound dispersion. This allows for the sound to be heard from any location within the room. Planar dipoles or ribbon speakers also offer a natural soundstage with very little resonance. This creates an immersive listening experience that brings the music to life in a way that is difficult to duplicate with other types of speakers.
Because they have such a large surface area, planar headphone magnetic speakers are also more durable than cone drivers, and can be operated at higher volumes without producing excessive vibration or distortion. They are also quieter than other types of speakers, which makes them a great option for home theatre and HiFi applications.
Due to their complex design, planar drivers can be more expensive than other kinds of loudspeakers, however they provide superior audio quality that is well worth the investment. In addition they have lower impedance than other kinds of loudspeakers. This means they are easier for amplifiers to drive than conventional drivers.
Planar magnetic speakers are a great option for home and professional use. However, they are not as popular in IEMs because they require more sophisticated engineering to fit into smaller forms such as headphones and earbuds. Recently, however there has been a rise in the number of IEMs available with planar magnetic technology. This includes the Rinko by Seeaudio, and the S12 and Z12 by LETSHOUER, which have proved to provide an exceptional listening experience.
Lower Distortion
Low distortion is the most desired characteristic for many audiophiles. Inductance in the voice coil is the most common source of distortion in speakers. When an alternating voltage is passed through the voice coil of a moving coil driver, the voice coil’s inductance produces magnetic field which causes the diaphragm to move. The movement or excursion is what creates the sound wave, but it also generates unwanted resonances and harmonics that degrade the quality of the audio.
One of the main advantages of magnetic planar speakers is that they feature less distortion than traditional drivers. This is due to the fact that the “voice coil” has an increased surface area instead of being squeezed into an extremely tiny space within a huge piece of metal. A well-designed planar magnet speaker can handle much more power than a dynamic driver without any audible strain.
Planar magnetic speakers can also reduce distortion by presenting a nearly perfect resistive load to the amplifier within the system. The voice coil is an extremely thin, long wire that acts as resistor. This makes the amplifier simple to drive and will sound the best when driven by an electric planar speaker.
Lastly, the high efficiency that magnetic planar speakers offer means that they generate very minimal heat when playing music at loud volumes. This is crucial as the excessive amount of heat can damage the voice coil and decrease the life span of the device.
However, this isn’t to claim that all single-ended planar magnetic speakers are unaffected by distortion. Due to their close magnet spacing, magnetic planar the magnetic forces can interact with each with one another and pull each other to a significant extent, causing changes in the diaphragm’s tension as time passes. This issue is made more difficult by the close proximity of adjacent rows of magnets.
Better Heat Dissipation
In the last few years, a number of specialization HiFi audio headphones companies have created incredible masterpieces using planar magnet technology. Planar magnetic drivers have some impressive advantages over the common coiled dynamics used in most headphones and speakers.
The “voice coil” is able to disperse heat more effectively than a cone speaker because it is spread over an area that is larger. This makes the voice coil perform more smoothly and with less distortion, and also enables an extremely lightweight diaphragm which can be driven to extremely high levels of excursion.
This allows the planar magnet speaker to have an extremely rapid transient response. Sharp peaks and tiny details can be reproduced with great precision even at very high SPLs. This also ensures that the sound is clear and free of distortion, and is not different from the original source material.
The impedance curve of a planar magnetic speaker is very flat, ranging from 4.2 ohms for the bass to 3.3 in the Treble. This makes it an easy load to drive amplifiers and is similar to the resistive loads that electronics manufacturers to showcase their products’ quality.
A ribbon/planar diaphragm that is extremely lightweight can move quickly and without much strain. This produces a very clear and clean sound with a very wide bandwidth and superb linearity.
The ribbon/planar design also is very quiet, which decreases distortion even further. It is also extremely robust across a wide range of temperatures, which enables the speaker to maintain a an even sound quality over long periods of time and over the entire listening area.
Although there are many benefits for using a ribbon/planar speaker, it is important to remember that this type of speaker is not appropriate for all applications or listeners. A ribbon/planar with a large radiating surface requires a large space to be able to deliver full-range sound with an adequate SPL. Most of these speakers are only sold as tweeters or as upper mid/high-range components in a two-way system of speakers.
Higher Power Handling
Magnetic planar drivers provide exceptional clarity and detail without the distortion that plagues traditional cone drivers. They can reveal subtle details in your music and reproduce complex sounds with accuracy. They also have a broad frequency response, which means they can produce a wider frequency range with greater accuracy.
Planar speakers produce a highly focused sound field, which can be a drawback when you’re listening in an area with other people. But it’s also what gives them their incredible dynamic range and pristine imaging. The sound is like a laser beam, emanating directly from the speakers. It is also heard even when you are off-axis.
The flat diaphragm as well as the acoustic wavefront also give them more space and depth than conventional cone speakers. They also have a less noise and are less distracting in noisy environments. Planar magnetic drivers are preferred by many audiophiles for their natural sound quality.
There are still some limitations with the technology. Planar drivers can be more difficult to manufacture and heavier than cone drivers. They can also be difficult to install in certain conditions. They also require more power to drive, which can limit the maximum output they can achieve.
Wisdom Audio is the leader in the application and development of PMD technology. Its products continue to expand the capabilities of this revolutionary technology. The patented material it uses can withstand temperatures much higher than PET that is the main ingredient in planar drivers. Its unique design also reduces the effects of diffraction which can occur when sound waves pass through small gaps and curves.
Speakers and headphones from this company are known for their exceptionally detailed and clear sound, devoid of distortion. They’re also more responsive than cone drivers which can help improve their bass response. They can also reproduce high frequencies with astonishing accuracy, and are capable of delivering deep, powerful bass.
