Magnetic Planar Speakers - Holographic 3D Imaging and Stunning Clarity
They create sound waves through vibrating a diaphragm, which is suspended between two magnets. Planar magnetic speakers are known for their holographic 3D imaging and breathtaking clarity.
They are also suitable for a wide range of audio applications because of their low distortion, wide horizontal and vertical dispersion and low costs.
Superior Sound Quality
When it comes to high-performance audio planar magnetic speakers are famous for their ability to produce clear, detailed sound with low distortion. This is due to the fact that they use an elongated diaphragm that has an conductive trace pattern that reacts to a magnetic field generated by magnets on either or both sides of the speaker. The diaphragm is moved and causes sound waves to be transmitted through the dipole-radiation pattern. This causes the diaphragm to vibrate more evenly and produce an improved sound quality than a typical dome or cone driver.
Another benefit of planar magnetic drivers is their large dispersion that is uniform, which lets the sound be heard from any position in the room. Additionally dipole or planar ribbon speakers provide an incredibly natural soundstage that has very little resonance. This gives you an experience of listening that is hard to duplicate with other types speakers.
Planar magnetic speakers have a greater surface area than cone drivers and are more durable. They can also operate at higher volumes without creating excessive distortions or vibrations. They also sound better than other types of speakers, making them an excellent choice for home theatre and HiFi applications.
Planar speakers are more expensive due to their complex design. However, they deliver superior audio quality and are well worth the investment. Additionally they have less impedance than other types of loudspeakers, meaning they are easier for amplifiers to drive than conventional drivers.
Although these advantages make planar magnet speakers a great choice for both professional and home applications, they are less popular in IEMs, as they require more advanced engineering to incorporate into small form factors such as headphones and earbuds. Recently, however there has been a rise in the variety of IEMs that feature planar magnetic technology. The Rinko by Seeaudio and the S12 & Z12 from LETSHOUER are two examples of IEMs that have proven to provide a great listening experience.
Lower Distortion
For many audiophiles the most sought-after characteristic of a speaker or headphone is its low distortion. The distortion that is produced in the speaker through a variety of elements, but perhaps the most popular 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 movement, or excursion, is what causes the sound wave, however it also generates unwanted resonances and harmonics which degrade the audio quality.
Magnetic planar speakers have a lower distortion than traditional dynamic drivers. This is due to the fact that the "voice coil" is spread out over an extensive surface instead of being squeezed into a small gap inside a huge chunk of metal. A well-designed planar magnet speaker can withstand more power than a dynamic driver with no audible strain.
Another way that planar magnetic speakers reduce distortion is to provide an almost perfect resistive load to the amplifier in the system. The voice coil is an extremely thin, long wire that behaves as an resistor. This makes it simple for the amplifier to drive and it always sounds its best when driving a planar magnetic speaker.
Lastly, the high efficiency magnetic planar speakers offer means that they generate very little heat when playing music at loud volumes. This is important, as a large amount can damage the voice coil and reduce the life span of the device.
However, this is not to say that all single-ended magnetic speakers are without distortion. Because of their proximity to the magnet spacing, the magnetic forces can interact and pull each other to a significant degree, which can result in changes to the diaphragm's elasticity over time. This issue is exacerbated due to the proximity of adjacent rows of magnets.
Better Heat Dissipation
Many specialized HiFi audio headphone companies have been creating amazing masterpieces over the last few years using planar magnetic technology. While many consider the common Coiled Dynamic Driver that the majority of headphones and speakers use to be superior, there are some remarkable advantages of using a planar magnet design.
The "voice coil" is able to disperse heat more effectively than a cone speaker since it has an area that is larger. This helps the voice coil operate more linearly and with less distortion, and also permits an extremely light diaphragm that can be driven to very high levels of excursion.
This allows the planar magnetic speaker to have an extremely fast transient response. Sharp peaks and tiny details can be reproduced with great precision, even at high SPLs. This also ensures that the sound is very clean and clear of distortion. It is not different from the original source material.
The planar magnetic speaker has a very flat impedance curve, ranging from around 4.2 Ohms in the bass, to 3.3 ohms in the treble. This makes it a simple load to drive amplifiers and is similar to the resistive loads used by electronics manufacturers to show their products' superiority.
Another advantage is that the ribbon/planar diaphragm is extremely light, allowing it to move extremely quickly and easily with less strain. This produces a very clean and clear sound with a wide frequency range and superb linearity.
The ribbon/planar design is also very quiet, which decreases distortion even further. It's also extremely stable across a broad temperature range which allows the speaker to produce high-quality audio that is consistent over long periods of listening and a large listening area.
While there are numerous benefits to using a Ribbon/Planar Speaker It is essential to keep in mind that this type of speaker is not appropriate for all listeners or applications. For instance, a ribbon/planar speaker with a large radiating panel requires an enormous space to produce full-range sound of adequate SPL. Most of these speakers are available as tweeters, or as upper mid/high range components in two-way speaker systems.
Higher Power Handling
Magnetic planar drivers offer clarity and clarity that is unmatched by cone drivers. They can reveal subtle variations and reproduce complex sounds with precision. They also have a wide frequency response, which means that they can produce a wider frequency range with greater accuracy.
Planar speakers create a highly directional sound field, which can be a problem if you're listening to them in the same room as other people. However, it's what gives them their incredible dynamic range and pristine imaging. The sound seems to be emitted directly from the speaker, similar to the sound of a laser beam, which can be heard even if you're off-axis.
The flat diaphragm in combination with the front of the acoustic wave, provides them with a higher sense of depth and space than cone speakers. They also tend to have less noise which makes them less distracting in noisy environments. Many audiophiles prefer the natural sound quality of planar magnetic drivers over other technology.
However, there are some limitations to the technology. a knockout post are more difficult to make than conventional cone drivers and they can be quite heavy, which makes them challenging to mount in certain conditions. They also require more power to drive, which could restrict the maximum output they can produce.
Wisdom Audio is the leader in the application and development of PMD technology. The company's products continue to advance the boundaries of this revolutionary technology. Its new patented materials can endure temperatures that are much higher than PET, which is used in the majority of planar drivers. Its unique design reduces the effects diffraction which can occur when soundwaves travel through narrow gaps or curves.
Speakers and headphones made by this company are known for their extremely clear and clean sound, free of distortion. They are also more responsive than cone drivers, which can enhance their bass response. They're also able to reproduce high frequencies with astonishing precision and produce powerful, deep bass.
