Magnetic Planar Speakers - Holographic 3D Imaging and Stunning Clarity
They create sound waves by vibrating a thin diaphragm which is suspended between two arrays of magnets. Planar magnetic speakers are famous for their amazing clarity and 3D holographic images.
They are also ideal for a variety of audio applications because of their low distortion, wide vertical and horizontal dispersion and affordable costs.
Superior Sound Quality
Planar magnetic speakers are known for delivering clear, precise sound with minimal distortion. They accomplish this by employing a flat diaphragm with a conductive pattern on it. This is a reaction to the magnetic field created by magnets, either on one or both sides of a speaker. This causes the diaphragm to move, producing sounds waves that are transmitted by a monopole or dipole radiation pattern. This allows the diaphragm to vibrate more evenly, and produce better sound quality than a typical cone or dome driver.
Planar magnetic drivers also benefit of a broad, uniform sound dispersion. This allows the sound to be heard from any position in the room. Additionally dipole or planar ribbon speakers have an unnatural and expansive soundstage that has very little resonance. This provides a unique listening experience that is hard to duplicate with other speakers.
Because they have such a large surface area, planar magnetic speakers are also more durable than cone drivers. They can be operated at higher volume levels without causing excessive vibration or distortion. They also have lower mechanical noise than other types of drivers, making them an excellent choice for home theater and HiFi applications.
Planar speakers are more expensive due to their intricate design. However, they provide better audio quality and are worth the investment. Planar speakers also have a lower impedance when compared to other kinds of loudspeakers. This makes them more suitable to drive amplifiers.
While these advantages make planar magnet speakers a great choice for home and professional applications however, they are not as popular in IEMs, as they require more sophisticated engineering to be integrated into smaller 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 IEMs that have proven to provide a great listening experience.
Lower Distortion
For many audiophiles the most sought-after feature of a speaker or headphone is the low distortion. Voice coil inductance is the most frequent source of distortion in speakers. When go!! alternating current is fed through a typical moving coil driver's voice coil, the inductance of the voice coil creates magnetic fields which induce diaphragm movement. The resulting movement, or excursion is what causes the sound wave to be generated but it also generates unwanted harmonics and resonances which affect the audio quality of the speaker.
One of the main advantages of magnetic planar speakers is that they are much less distortion than traditional drivers. This is due to the fact that the "voice coil" has an increased surface area rather than being squeezed into a tiny space within a huge piece of metal. In the end, an appropriately designed planar magnetic speaker can withstand a greater amount of power than traditional dynamic drivers without any sound.
Planar magnetic speakers are also able to reduce distortion by presenting the perfect resistive load to the amplifier within the system. This is due to the fact that the voice wire is a long thin wire that acts exactly like a resistor. This makes it easy for the amplifier to drive, and it always sounds best when driving the planar magnetic speaker.
Additionally, the high efficiency that magnetic planar speakers offer means that they generate very minimal heat when playing music at loud volumes. This is important because the heat produced can cause damage to the voice coil, decreasing its lifespan and causing distortion.
However, this does not mean that all planar magnetic single-ended speakers are distortion free. Because of their proximity to the magnet spacing, magnetic forces can interact and draw each other to a significant extent, causing changes to the diaphragm's elasticity as time passes. This problem is made worse due to the proximity of the adjacent rows of magnets.
Better Heat Dissipation
Many specialist HiFi audio headphone companies have been creating amazing masterpieces in recent years that utilize planar magnetic technology. Although many believe that the standard coiled dynamic driver the majority of headphones and speakers use to be superior, there are incredible advantages to using a planar magnetic design.
The "voice coil" can dissipate the heat more efficiently than a cone speaker as it is spread over an area that is larger. This lets the voice coil perform more smoothly and with less distortion, and allows a lightweight diaphragm which can be driven at extremely high excursion levels.
This enables the planar magnet speaker to have an extremely rapid transient response. Sharp peaks and even the smallest details can therefore be reproduced with great precision, even at high SPLs. This also means that the sound is very clean and clear of distortion. It is not different from the original source material.
The planar magnetic speaker also 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 an easy load to drive amplifiers and similar to the resistive loads used by electronics manufacturers to show their products' quality.
A ribbon/planar diaphragm that is extremely light and compact can move quickly and without much strain. This creates a crystal clear and clear sound, with a wide frequency range and superb linearity.
The ribbon/planar design also is extremely quiet, which helps to reduce distortion even more. It is also very stable across a wide temperature range, allowing the speaker to maintain the same quality of sound throughout long listening sessions and a large listening area.
While there are numerous benefits to using a Ribbon/Planar Speaker It is essential to remember that this kind of speaker is not suitable for all applications or listeners. A large ribbon/planar radiating surface will require a larger room in order to produce 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 deliver clarity and clarity that is superior to cone drivers. They can reveal subtle nuances in your music, and reproduce complex sounds with precision. They have a broad frequency response that allows them to produce a greater range of frequencies accurately.
Planar speakers produce a directed sound, which could be a problem if you are listening to them along with others. But it's also what gives them their incredible high-quality sound and crystal clear image. The sound seems to emanate 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 and the acoustic wavefront also give them more depth and spaciousness than traditional cone speakers. They are more likely to have a low noise floor which makes them less distracting when in noisy environments. Many audiophiles prefer the natural sound quality of planar magnetic drivers over other technology.
However, there are limitations to the technology. Planar drivers are more difficult to create than conventional cone drivers and they can be quite heavy, which makes difficult to install in certain environments. They also require a greater power output to drive them, which could restrict their maximum output.
Wisdom Audio is the leader in the research and application of PMD technology. The company's products continue to push forward the limits of this innovative technology. Its new patented materials can withstand temperatures far higher than PET, which is commonly used in most planar drivers. Its unique design reduces the effects diffraction which can occur when soundwaves travel through narrow gaps or curves.
The headphones and speakers made by this company are known for their extremely clear and clear sound, devoid of distortion. They are also more responsive than cone drivers, which helps enhance their bass response. They're also capable of reproducing high frequencies with astonishing precision, and they can produce powerful, deep bass.
