Planar Magnetic Speakers
Planar magnetic speakers convert an electrical signal into sound by with a flat diaphragm. They are well-known for their accuracy and detail, as well as low distortion. They also have a wide frequency response, making them easy to listen to.
Dynamic drivers have much more robust and rigid diaphragms than the ultra-light and thin ones that are used in planar magnetic speakers. This hinders their ability to move and accelerate rapidly, leading to sonic distortion.
They are easy to build
Many people believe that building planar magnet speakers is difficult. However they are extremely easy to build. The key is to follow the directions and build a high-quality speaker. The result will be a sound system of high quality that can compete with any model that is available commercially. Besides being easy to build, planar magnetic speakers also offer better sound quality than traditional dynamic drivers. They offer superior detail, a wider dynamic range and controlled directivity which all make for an experience that is more immersive.
Planar magnetic speakers emit high-frequency, flat waves,
driver planar unlike conventional loudspeakers which project sound along circular wavefronts. This enables them to reproduce sound at extremely low frequencies, which could be difficult for traditional speakers to achieve. Additionally, their precise image can bring the music to life in a way that makes traditional speakers sound slow compared to.
To produce a sound wave, a
driver planar magnetic makes use of a thin metal film suspended between two conductive panels that are stationary. The audio signal is carried by through the panel, and it quickly changes between negative and positive. The magnetic array moves the panel's negative side forward and back and causes the diaphragm of the panel to move. The result is a superb dynamic response and a large soundfield that is not distorted.
One of the most important elements in a planar magnet speaker's performance is its maximum excursion, which is how the speaker can travel before it starts to distort. It is typically measured at a particular frequency and at a certain output level. For instance, if want to hear a 20-Hz bass note, you'll need a speaker with an excursion of around 1 mm.
A reliable planar magnet driver should be able to maintain structural integrity while enduring high excursion. It should be able to disperse heat effectively and handle a significant amount of power. To fulfill these goals the voice coil of the speaker must be with sufficient thickness and size. In addition the voice coil should be wrapped in an conductive material that is able to conduct electricity.
They efficiently disperse heat
This is a crucial aspect of any speaker, especially one that is planar magnetic. The voicecoil is closely connected to the magnet array and has a very high flux density across the gap. This is the cause of heat in a speaker and it needs to be eliminated to prevent distortion and damage. Radiation and convection are two ways that the voicecoil can get rid of heat. Radiation is preferred since it does not have the pumping effects of cone movement. However, it should be done with attention and the design should be able to handle the power that is applied.
The first step is to ensure that the distance between your voicecoil array as well as the array is at least 1mm. This is crucial, since gaps that are larger than 1mm can cause some serious distortion. The gap must also be large enough to permit the voicecoil to move without hitting the rearplate. The wide gap designs that are popular among manufacturers are not efficient and only work at low frequencies.
Put a magnet in the gap, and then measure the resistance. The greater resistance,
driver planar the less heat is dissipated, and the more likely it is to distort. The lower the resistance the more efficient the speaker will be and the less distortion it will produce.
Planar magnetic speakers reproduce the upper octaves very precisely, but are not able to reproduce lower frequencies due to the massive diaphragm needed. Many planar magnetic speakers combine the woofer and a tweeter. This allows them to cover a larger frequency range with less distortion.
Planar magnetic drivers are known for their low distortion and great bass. The dipole design makes they emit equal amounts of energy in both directions with an inverted phase. This is a huge advantage over conventional drivers, which are susceptible to strong Q resonances and mechanical distortion.
They can handle a great amount of power
The truth is that planar magnetic speakers are able to provide the power they require. The "voice coil" has a greater surface area than a dynamic driver and can thus disperse more heat. The diaphragm, which is thin and light, also aids in reducing distortion.
It's important to keep in mind that a planar magnet speaker will require an enormous amount of power to produce a good sound. They aren't able to disperse energy like a conventional speaker, which means that they can be sensitive to how the room is set up. Additionally, they're directed, which means that listening to them from a few degrees off-axis can result in the perceived volume of the sound dropping dramatically.
Inefficiency is another reason that makes them able to handle a large amount of power. They have a lower impedance and therefore require more power to reach the same volume. They are also prone to magnetic saturation that can cause distortion.
An excellent way to test the capacity of a planar magnetic speaker to withstand a lot of power is to test its maximum excursion. This is the distance that the diaphragm can move before it comes into contact with the magnet array and starts to distort. The best planar speakers can attain a maximum of 1 mm.
Planar magnetic speakers may also offer a higher frequency response than conventional cone drivers, which could be a benefit in some situations. They can reproduce a higher number of frequencies, which can improve the quality of sound and music. This makes it easier to distinguish between vocals and instruments in a song.
The top planar magnetic speakers can reproduce a broad spectrum of frequencies, including the bass frequencies. This can be a huge benefit for people who wish to enjoy music in a variety of environments. These speakers are more expensive than traditional speakers, but provide a unique immersive experience. They are also a good choice for home theater systems.
They are directed
When an electrical signal is applied to the conductive trace pattern, the magnetic field triggers a diaphragm movement that creates sound waves. The movement is much more precise and controlled than traditional cone drivers, which allows for a larger frequency response. This allows planar speakers to produce more detail and clarity in the music.
These diaphragms that are flat can be designed to be either dipole (radiating equally in front and back like electrostatics or Maggies) or Monopole (radiating only in the direction of forward, more like conventional dynamic speakers). This flexibility provides designers with a wide range of options for wall or in-wall loudspeakers that could provide exceptional performance at affordable cost.
The diaphragm of a
planar magnetic technology magnetic driver is typically constructed of a light, thin polymer coated with copper circuits that conduct electricity. The metal-laced diaphragm is surrounded by an array of magnets that are arranged in bars with a wide spacing. The magnets in these bars create a powerful magnetic field that can draw and disperse air particles in the diaphragm. The magnetic fields also aid to disperse heat away from the speaker without creating any strain to the voice coil.
