Planar Magnetic Speakers
Planar magnetic speakers utilize a flat diaphragm to convert an electrical signal into sound. They are known for accuracy as well as their clarity and detail. They also have low distortion. They also have a broad frequency response, making them easy to listen to.
The diaphragms of dynamic speakers are significantly heavier and stiffer than the ones used in planar magnet speakers. This hinders their ability to move and accelerate quickly which can result in distortion of the sound.
These are easy to construct
Many people believe that building planar magnet speakers is hard. However they are extremely easy to build. It is crucial to follow the directions carefully and construct an audio system that is well-engineered. The result will be an excellent audio system that can compete with any available model. Planar magnetic speakers are simple to build and provide superior audio quality when compared to traditional dynamic drivers. They offer superior detail as well as a larger dynamic range and controlled direction which all help to create an experience that is more immersive.
Planar magnetic speakers emit high-frequency, flat waves, unlike conventional loudspeakers which project sound along circular wavefronts. They can reproduce low-frequency sound, which is not possible with conventional speakers. Their precise image brings the music to life, making standard speakers sound slow 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 transmitted as an electric current to the panel which quickly shifts between negatives and positives. The magnetic array moves the panel's negative end forward and back and causes the diaphragm of the panel to vibrate. The result is a superb dynamic response and a large soundfield with minimal distortion.
The maximum excursion of a planar magnet speaker is among the most important aspects in its performance. This is the most distance the speaker can travel before it starts to distort. best planar magnetic iem is usually measured at a particular frequency and at an output level. For instance, if 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 magnetic driver should be able to handle high excursion while maintaining its structural integrity. It should be able disperse heat efficiently and handle a significant amount of power. The voice coil of the speaker should be thick enough and large enough to satisfy these specifications. Additionally the voice coil should be wrapped with a conductive material that can conduct electricity.
They efficiently disperse heat.
This is an important aspect of any speaker, but especially one with a planar magnetic. The voicecoil is closely connected to the magnet array and has a high flux density across the gap. This is the cause of heat in a speaker and it has to be cooled down to prevent distortion and damage. The voicecoil can be used in two ways of getting rid of heat - convection and radiation. Radiation is the preferred option since it doesn't have the pumping effects of the cone's movement, however, it should be done with care and the design has to be able to handle the power being applied.
The first step is to ensure that the gap between your voicecoil array and array is at least 1mm. This is critical, as the gap can create some pretty horrible distortion if it's greater than this. The gap should be large enough to allow the voicecoil's movement to avoid hitting the rearplate. For this reason, the wide gap designs that are favored by a variety of manufacturers are not efficient and will only work well at low frequencies.
Place a magnet over the gap and measure the resistance. The higher the resistance, the lower heat is dissipated and the more likely it is to distort. The lower the resistance the more efficient and free of distortion the speaker will be.
Planar magnetic speakers are able to reproduce the upper octaves with amazing accuracy, but they can't replicate the lower frequencies since they require a huge diaphragm. This is the reason why many planar magnetic speakers use a woofer and tweeter in combination. This allows them to cover a larger frequency range with less distortion.
In addition to their amazing bass, planar magnetic drivers have very low distortion. The dipole design makes the drivers radiate equal amounts of energy in both directions, with an inverted phase. This is a significant advantage over conventional drivers which can be subject to strong Q resonances as well as mechanical distortion.
They can handle a huge deal of power
Many people are worried that planar magnetic speakers will not be able to handle the amount of power they require, but the truth is that they do. 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 helps to reduce distortion.
It's important to remember that a planar magnet speaker will still require lots of power to create the best sound. They are sensitive to the way in which the room is set up because they aren't able to disperse their energy as the traditional speaker. Furthermore, they are direction-specific, which means listening from just a few degrees off-axis could result in the sound level dropping significantly.
Another reason for their capacity to handle a lot of power is that they are inefficient. They have lower impedances and therefore require more power to achieve the same amount. They are also prone to magnetic saturation, which can cause distortion.
One of the best ways to determine the capability of a planar magnetic speaker to handle lots of power is to test its maximum excursion. This is the length the diaphragm can move before it comes into contact with the magnet array and starts to distort. The best planar speakers can achieve a maximum distance of 1 millimeter.
Planar magnetic speakers also offer a greater range of frequencies than cone drivers. This is beneficial in certain circumstances. They can reproduce a larger amount of frequencies, which could enhance the quality of sound and music. This can make it easier to differentiate between vocals and instruments in the song.
The top planar magnetic speakers can reproduce a wide range of frequencies, which includes the bass frequencies. This is a major benefit for people who wish to enjoy music in a variety of environments. These speakers are more expensive than traditional loudspeakers, but offer a distinct immersive experience. They're also a great option for home theater systems.
The direction of the arrow is important
When an electrical signal is positioned to the trace patterns that conduct electricity, the magnetic field creates diaphragm movement that generates sound waves. The movement is more precise and controlled in comparison to traditional cone drivers. This allows for more frequency response. This enables planar speakers to produce more clarity and detail in the music.
These diaphragms with flat sides are available in two designs that are dipole (radiating in both directions, similar to electrostatics and Maggies) or monopole (radiating in just one direction, much like traditional dynamic speakers). This flexibility lets designers choose from a variety of options when designing on-wall or built-in loudspeakers. They can deliver excellent performance at reasonable prices.
The diaphragm of a planar magnetic driver is usually composed of an ultra-thin and light polymer that is coated with a circuit made of copper which conducts electricity. The metal-laced diaphragm is surrounded by arrays of magnets in wide-spaced bars. The magnetic bars create an intense magnetic field that can attract and disperse air particles in the diaphragm. The magnetic fields also help to disperse heat away from the speaker without causing an audible strain on the voice coil.
Planar magnetic speakers have greater sensitivity than conventional cone speakers, and they can handle large amounts of power without overheating. They also have a low impedance that means that they require less amplification to reach the same listening quality. They can reproduce a full range of audio frequencies, including highs and bass. They are usually enhanced by boxed subwoofers, which can reproduce low frequency sounds with greater precision.
The relatively low damping of single-ended planear magnet loudspeakers is a disadvantage. This can result in high-Q resonances at the lower frequency end of the speaker's response, which can cause coloration of the sound. The solution is a hybrid design, which combines the advantages of planar and dipole technologies.
One of the most important factors that determine the success of a planar magnetic speaker is proper positioning in a room. This affects several sound characteristics, including bass response imaging, soundstage depth and breadth. It is important to avoid toe-ins, as it can negatively impact the mid-range and highs. The ideal speaker will be located at the point where the central image is at its most narrow.
