Why No One Cares About Planar Magnetic Speakers
Planar Magnetic Speakers
Planar magnetic speakers convert an electrical signal to sound with flat diaphragms. They are renowned for their precision and clarity and also their low distortion. They are able to handle a wide range of frequencies, making them easy to listen.
The diaphragms of dynamic speakers are much stiffer and heavier than those used in planar magnet speakers. This hinders their ability to move and accelerate rapidly, causing sonic distortion.
They are simple to construct.
Many people think that building planar magnetic speakers is a challenge, but they are extremely simple to construct. The trick is to follow the steps and construct a well-engineered speaker. The result will be a high-quality audio system that can compete with any commercially available model. Apart from being simple to construct, planar magnetic speakers also offer superior sound quality than traditional dynamic drivers. They offer superior clarity, extended dynamic range, and a more controlled directivity that all contribute to a full listening experience.
Planar magnetic speakers emit high-frequency, flat waves, in contrast to conventional loudspeakers which project sound along circular wavefronts. This allows them to reproduce sounds at extremely low frequencies, which could be difficult for traditional speakers to achieve. In addition, their incredibly precise imaging can bring the music to life in a manner that makes standard speakers sound sluggish in comparison.
A planar magnetic drive generates a sound by using a thin sheet of metal suspended between two stationary conductive plates. The audio signal runs a current through the panel, which quickly switches between positive and negative. The negative portion of the panel is drawn toward the magnetic array and it moves around to shake the diaphragm. The result is a broad sound field that is free of distortion and an excellent dynamic response.
The maximum distance of an acoustic speaker is one of the most important aspects in its performance. This is the maximum distance the speaker can travel before it begins to distort. This is measured at a particular frequency and output level. For example, if you want to hear a 20-Hz bass note, you will require a speaker that has a maximum excursion of about 1 millimeter.
A good planar magnet driver should be able maintain structural integrity even during high excursion. It should also be able efficiently disperse heat and handle lots of power. To meet these goals the voice coil of a speaker must be sufficiently thick and wide. Additionally the voice coil needs to be wrapped with a conductive material that can conduct electricity.
They efficiently disperse heat.
This is an essential aspect of any speaker, especially one with a planar magnetic. The voicecoil is extremely close to the magnet array and has an extremely high flux density within the gap. This is the reason for heat in a speaker and it needs to be eliminated to avoid damage and distortion. The voicecoil has two methods to get rid of heat - convection and radiation. Radiation is the preferred method because it doesn't have the cone's pumping effect. However, it should be done with careful consideration and the design must manage the power being that is applied.
The first step is to make sure that the distance between the array and the voicecoil is a minimum of 1 millimeter. This is vital, because the gap could cause quite a bit of distortion if it's greater than this. The gap should be large enough for the voicecoil to move without hitting the rear plate. This is why the wide gap designs favored by many manufacturers are inefficient and will only work well at low frequencies.
A good way to determine the gap is to put a magnet in the gap and measure the resistance between the magnet and the voicecoil. The greater the resistance, 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 can reproduce the upper octaves of sound with amazing precision, however they can't replicate the lower frequencies since they require a large diaphragm. This is the reason why the majority of planar magnetic speakers utilize a woofer and a tweeter in combination. This allows them to cover a larger frequency range with less distortion.
In addition to their superb bass In addition to their excellent bass, planar magnetic drivers have a very low distortion. www.headphonesshop.uk is because they are a dipole which means that they emit equal energy front and back, with an inverted phase. This is a major advantage over conventional drivers which can be subjected to mechanical distortion and strong Q resonances.
They can handle a huge deal of power
Many people are worried that planar magnetic speakers will not be capable of handling the amount of power that they need however the truth is that they can. This is due to the fact that the "voice coil" is spread over more space than it would be in a conventional dynamic driver, which means that it is able to disperse heat more efficiently. The diaphragm, which is small and light, helps to reduce distortion.
It's important to keep in mind that a planar magnetic speaker will still require an enormous amount of power to produce an excellent sound. They can't easily disperse energy as a conventional speaker, which means that they are sensitive to the way the room is set up. They are also directional which means that if you listen from just a few degrees away, the volume is likely to be diminished.
Inefficiency is another aspect that allows them to handle a large amount of power. This is due to a much lower impedance than conventional drivers, meaning they need more power to attain the same listening volume. Furthermore, they are susceptible to magnetic saturation, which can cause them to distort.
One of the best ways to test the capacity of a planar magnetic speaker to handle loads of power is to test its maximum excursion. This is the maximum distance that the diaphragm is able to travel before it begins to distort when it hits the magnet array. The best planar speakers can reach a maximum distance of 1 millimeter.
Planar magnetic speakers can also offer a wider frequency response than traditional cone drivers, which can be a benefit in some situations. They can produce higher frequencies, which can enhance the quality of music. This makes it easier to distinguish between instruments and vocals in the song.
The best planar magnetic speakers can reproduce a broad range of frequencies, which includes the bass frequencies. This is a huge benefit for people who want to enjoy music in different settings. These speakers are more expensive than traditional speakers, but provide a unique immersive experience. These speakers are also good for home theater systems.
They are directional
When an electrical signal is placed on the conductive trace patterns the magnetic field creates movement of the diaphragm which generates sound waves. The movement is more precise and controlled as compared to traditional cone drivers. This enables more frequency response. This allows planar speakers to produce more clarity and detail in the music.
These flat diaphragms are available in two designs: dipole (radiating in both directions, similar to electrostatics and Maggies) or monopole (radiating only in one direction, much like traditional dynamic speakers). This flexibility lets designers select from a range of options when designing wall or built-in loudspeakers. They can deliver high-quality performance at an affordable price.
The diaphragm inside a planar magnetic driver is usually composed of an ultra-thin and light polymer that is coated with a copper circuit which conducts electricity. The metal-laced diaphragm is surrounded by an array of magnets that are arranged in bars with a wide spacing. These arrays of magnetic bars create an extremely strong magnetic field that can draw and disperse air particles in the diaphragm. The magnetic fields help radiate the heat away from speakers without straining the voice coil.
Planar magnetic speakers have a greater sensitivity than cone speakers that are conventional, and they can handle large amounts of power without overheating. They also have a low impedance that means they require less amplification to reach the same listening quality. They can reproduce the full range of audio frequencies including highs and bass. They are usually enhanced by subwoofers that are boxed, which can reproduce low-frequency sounds with greater accuracy.
The relatively low damping of single-ended planar magnetic loudspeakers is a drawback. This can lead to high-Q resonances in the low frequency of the speaker's response, which can cause a coloration of the sound. This issue can be addressed by a hybrid design which blends the advantages of planar and dipole technology.
One of the most crucial factors for the success of a planar magnetic speaker is the correct positioning in a room. This affects several sound characteristics, including bass response imaging, soundstage depth and breadth. Toe-in can adversely affect the midrange and the higher frequencies. In the ideal scenario, the speaker should be placed in the area where the central image is at its narrowest.
