Planar Magnetic Speakers
Planar magnetic speakers convert an electrical signal to sound using flat diaphragms. They are renowned for their accuracy and clarity, as well as low distortion. They have a wide spectrum of frequencies, making them easy to listen.
The diaphragms of dynamic speakers are much heavier and stiffer than the ones used in planar magnet speakers. This limits their ability for them to accelerate and move quickly, causing sonic distortion.
They are easy to build
Many people think that building planar magnetic speakers is difficult but they're extremely easy to build. It is essential to follow the directions carefully and create a speaker that is designed properly. The result will be a high-quality audio system that is able to compete with any model that is commercially available. Apart from being simple to construct these speakers offer better sound quality than traditional dynamic drivers. They offer superior detail, a wider dynamic range, and a more controlled directivity that all make for an immersive listening experience.
Contrary to conventional loudspeakers, which project sound in circular wave fronts, planar magnetic speakers emit flat waves that are directional. relevant resource site enables them to reproduce sounds at very low frequencies, which can be difficult for conventional speakers to achieve. Additionally, their precise imaging can bring music to life in a way that makes standard speakers sound sluggish in comparison.
To create a sound wave, a planar driver uses a thin metal film suspended between two stationary conductive panels. The audio signal is carried by through the panel, which rapidly changes between negative and positive. The magnetic array moves the panel's negative end in a circular motion and causes the diaphragm of the panel to vibrate. The result is a great dynamic response, and a broad soundfield, with no distortion.
One of the most crucial elements in a planar magnet speaker's performance is its maximum excursion, which refers to how the speaker's movement can be measured before it starts to distort. It is typically measured at a specific frequency and at a certain output level. If you'd like to hear the 20-Hz bass, you'll require an audio system that has an excursion of around 1 mm.
A good planar magnet driver must be able to maintain structural integrity even during high excursion. It should be able to disperse heat effectively and handle a large amount of power. To meet these requirements, the speaker's voice coil must be with sufficient thickness and size. The voice coil must also be wrapped in a material capable of conducting electricity.
They effectively disperse heat
This is a crucial aspect of any speaker, especially a planar magnetic. The voicecoil is closely connected to the magnet array and has a very high flux density across the gap. Heat is generated by the voicecoil and must be emitted to prevent damage and distortion. The voicecoil has two methods of getting rid of heat: convection and radiation. Radiation is preferred since it doesn't have the cone's pumping effect. However, it has to be done with attention and the design should be able to handle the power that is used.
The first step is to make sure that the distance between the array and the voicecoil is a minimum of 1 millimeter. This is critical, as the gap can cause very unpleasant distortion if greater than this. The gap should also be large enough to permit the voicecoil's movement without hitting the rearplate. The wide gap designs that are popular with manufacturers are not efficient and only work at low frequencies.
A good way to determine the gap is to put a magnet over the gap and determine the resistance between the magnet and the voicecoil. The higher the resistance the less heat will be dissipated and the greater the risk of distortion. The lower the resistance the more efficient and free of distortion the speaker will be.
Planar magnetic speakers can reproduce the upper octaves with amazing precision, however they can't reproduce the lower frequencies because they require a very large diaphragm. A lot of planar magnetic speakers incorporate the woofer and a tweeter. This lets them cover a wider frequency range with less distortion.
Planar magnetic drivers are renowned for their low distortion and excellent bass. This is due to the fact that they are a dipole which means that they emit equal energy front and back using inverted phase. This is a major advantage over traditional drivers that are subject to mechanical distortion and strong Q resonances.
They can handle a great deal of power
Many people are worried that planar magnetic speakers won't be capable of handling the amount of power that they need, but the truth is that they can. The "voice coil" has a greater surface area than a dynamic driver, and can therefore dissipate more heat. The diaphragm, which is small and light, aids in reducing distortion.
It is important to keep in mind that a planar magnet speaker will still require a lot power to produce a good sound. They aren't able to disperse energy as a conventional speaker, so they can be sensitive to how the room is installed. Additionally, they're directed, which means that listening with a few degrees off-axis can result in the perceived sound level dropping significantly.
Another factor that affects their ability to handle a lot of power is the fact that they are inefficient. They have lower impedances, so they require more power to reach the same amount. In addition, they are susceptible to magnetic saturation, which could cause them to distort.
In determining the maximum excursion for a planar magnet speaker is a great way to test its capacity to handle high-power. This is the maximum distance that the diaphragm is able to travel before it begins to distort after hitting the magnet array. The most effective planar speakers will attain a maximum of 1 mm.
Planar magnetic speakers also have a greater frequency range than cone drivers. This is beneficial in certain situations. They can reproduce a higher quantity of frequencies, which could enhance the quality of music and sound effects. This makes it easier to differentiate between vocals and instruments in the song.
The best planar speakers are able to reproduce a variety of frequencies including bass frequencies. This is an excellent advantage for people who want to enjoy music in different settings. These speakers are more expensive than traditional speakers, but offer a unique, immersive experience. They're also a great choice for home theater systems.
The direction of the arrow is important
When an electrical signal is applied to the conductive trace pattern the magnetic field creates a movement of the diaphragm that generates sound waves. The movement is more precise and controlled compared to conventional cone drivers. This enables a greater frequency response. This enables planar speakers to produce more clarity and detail in music.
These flat diaphragms are available in two distinct designs: dipole (radiating in both directions, like electrostatics and Maggies) or monopole (radiating only in one direction, much like traditional dynamic speakers). This flexibility allows designers to choose from a wide range of options when designing on-wall or built-in loudspeakers. They can deliver excellent performance at reasonable prices.
The diaphragm of a planar magnet driver is typically constructed of a thin, light polymer, coated with copper circuits that conduct electricity. The diaphragm that is coated with metal is surrounded by a variety of magnets that are arranged in bars with a wide spacing. The magnetic bars create a powerful magnetic field which can attract and disperse air particles within the diaphragm. The magnetic fields also help to radiate heat away from the speaker without creating audible strain on the voice coil.
Planar magnetic speakers have higher sensitiveness than cone speakers that are conventional and are able to handle large amounts of power without overheating. They also have a low impedance, which means that they require less amplification in order to achieve the same listening level. They can reproduce a full range of frequencies including highs and bass. They are often enhanced with subwoofers with boxed enclosures, which are able to reproduce low frequency sounds with greater precision.
The comparatively poor damping of single-ended planar magnet loudspeakers is a drawback. This can lead high-Q resonances within the low frequency spectrum of the speaker's response, which can color the sound. This problem can be solved through a hybrid design that combines the benefits of both dipole and planar technologies.
Proper placement of a planar magnet speaker in the room is among the most crucial elements that determine its success. This impacts a variety of aspects of sound, such as bass response, imaging, soundstage depth and breadth. It is crucial to avoid toe-ins, because it could negatively impact the mid-range and highs. The ideal speaker will be placed at the point where the central image is at its thinnest.
