Do You Know How To Explain Planar Magnetic Speakers To Your Mom

Planar Magnetic Speakers

Planar magnetic speakers convert electrical signals to sound using flat diaphragms. They are known for their clarity and accuracy, as well as low distortion. They also have a wide frequency response, which makes them easy to listen to.

The diaphragms of dynamic drivers are significantly heavier and stiffer than those used in planar magnetic speakers. This limits their ability to accelerate and move quickly which can result in distortion of the sound.

They are easy to build

Many people believe that building planar magnet speakers is difficult. However they are incredibly simple to construct. It is crucial to follow the directions carefully and build a speaker that is well-engineered. The result will be a high-quality audio system that will rival any commercially available model. Besides being easy to build these speakers offer superior sound quality than traditional dynamic drivers. They have superior clarity as well as a larger dynamic range and controlled directivity that all contribute to an experience that is more immersive.

Planar magnetic speakers emit high-frequency, flat waves, in contrast to conventional loudspeakers that project sound in circular wavefronts. This allows them to reproduce sounds at extremely low frequencies, which could be difficult for standard speakers to achieve. Their extremely precise image brings the music to life, making traditional speakers sound slow in comparison.

To create a sound wave, a driver planar magnetic uses a thin metal film suspended between two conductive panels that are stationary. The audio signal sends a current to the panel, which quickly shifts between negatives and positives. The magnetic array moves the panel's negative end in a circular motion, causing the diaphragm to vibrate. The result is an excellent dynamic response and a wide soundfield that is not distorted.

One of the most important aspects of a planar driver magnetic speaker's performance is its maximum excursion, which is how the speaker can travel before it begins to distort. This is measured at a certain frequency and output level. For instance, if want to hear a 20-Hz bass note, then you'll require a speaker with a maximum excursion of about 1 mm.

A solid planar magnetic driver must be able to withstand high excursion while maintaining its structural integrity. It should also be able disperse heat effectively and handle a lot of power. To fulfill these requirements the voice coil of the speaker must be with sufficient thickness and size. Additionally, the voice coil must be wrapped with an conductive material that is able to conduct electricity.

They effectively disperse heat.

This is a very important aspect of any speaker. The voicecoil is in close proximity to the magnet array and has a high flux density across the gap. This is the source of heat in a speaker and it needs to be eliminated to prevent distortion and damage. Convection and radiation are the two ways in which the voicecoil is able to get rid of heat. Radiation is preferred because it doesn't have the cone's pumping effect. However, it has to be done with careful consideration and the design must manage the power being applied.

The first step is to ensure that the distance between the voicecoil and the array is a minimum of 1 millimeter. This is vital, as a gap larger than 1mm could cause serious distortion. The gap should be large enough to permit the voicecoil's movement without hitting the rearplate. The wide gap designs that are popular with manufacturers are inefficient, and only work at low frequencies.

Put a magnet in the gap, and then measure the resistance. The higher the resistance the less heat will be dissipated and the greater the likelihood of distortion. The lower the resistance is, the more efficient and distortion-free the speaker will be.

Planar magnetic speakers can reproduce the upper octaves of sound with amazing precision, however they aren't able to reproduce lower frequencies since they require a huge diaphragm. That's why the majority of planar magnetic speakers utilize a woofer and tweeter together. This lets them cover a larger frequency range with less distortion.

Planar magnetic drivers are well-known for their low distortion and excellent bass. The dipole design means that the drivers radiate equal amounts of energy in both directions, with an inverted phase. This is an advantage over traditional drivers that can be subject to mechanical distortion and strong Q resonances.

They can handle plenty of power

Many people are concerned that planar magnetic speakers won't be capable of handling the amount of power that they need however the reality is that they are able to. This is because the "voice coil" is spread over more space than it would be in a traditional dynamic driver, which means it can dissipate heat more effectively. The diaphragm, which is small and light, also assists in reducing distortion.

However, it's important to keep in mind that an acoustic speaker planar will require to be driven by a large amount of power to create a excellent sound. They aren't able to disperse energy like a traditional speaker, which means that they can be sensitive to how the room is installed. Additionally, they're direction-specific, which means listening to them from just a few degrees off the axis could result in the perceived sound level dropping significantly.

Inefficiency is another reason that allows them to handle a large amount of power. They have a lower impedance which means they require more power to achieve the same volume. They are also prone to magnetic saturation, which can cause distortion.

An excellent way to test the capacity of a planar magnetic speaker to handle a lot of power is to determine its maximum excursion. This is the length that the diaphragm can travel before it begins to distort when it hits the magnet array. The most powerful planar magnetic speakers can reach the distance of around 1 mm before this occurs.

Planar magnetic speakers may also provide a greater frequency response than traditional cone drivers, which could be beneficial in certain situations. They can reproduce a greater amount of frequencies, which could improve the quality of music and sound effects. This can make it easier to distinguish between instruments and vocals in the song.

The top planar magnetic speakers can reproduce a broad spectrum of frequencies, including the bass frequencies. This is a major benefit for those who want to listen to music in a variety of settings. These speakers can be more expensive than standard loudspeakers but they offer a unique and immersive experience. These speakers are also suitable for home theater systems.

They are directional

When an electrical signal is applied to the trace pattern that conducts electricity, the magnetic field creates a movement of the diaphragm that creates sound waves. The movement is more precise and controlled compared to traditional cone drivers. This enables more frequency response. This enables planar speakers to produce more clarity and detail in music.

These diaphragms that are flat can be designed to be dipole (radiating equally in both directions like electrostatics or Maggies) or Monopole (radiating only in the forward direction, more like conventional dynamic speakers). This flexibility lets designers select from a range of options when designing on-wall or built-in loudspeakers. They can provide outstanding performance at a reasonable price.

The diaphragm in a planar magnetic driver is usually constructed from an ultra-thin, driver planar light polymer that is coated with a circuit made of copper that can conduct electricity. The diaphragm with metal is enclosed by magnets in bars that are widely spaced. The magnetic bars create an intense magnetic field that can draw and disperse air particles inside the diaphragm. The magnetic fields also aid to radiate heat away from the speaker, without causing an audible strain on the voice coil.

Planar magnetic speakers are more sensitive than cone speakers and are able to handle a lot of power without overheating. They also have a low impedance, which means that they require less amplification in order to achieve the same listening quality. They can reproduce a broad range of frequencies including highs and bass. They are usually paired by woofers with boxes that can reproduce low frequencies with greater precision.

The comparatively poor damping of single-ended planear magnet loudspeakers is a disadvantage. This can result in high-Q resonances in the low frequency range of the speaker response, Driver Planar which may color the sound. The solution to this issue is a hybrid design, that combines the benefits of planar and dipole technologies.

The correct positioning of a planar magnet speaker in a room is one of the most important factors that determine its success. A variety of sound characteristics are affected by this, such as the bass response, imaging, and the width and depth of the soundstage. Toe-in is a negative influence on the midrange and the higher frequencies. The ideal speaker will be placed at the point where the central image is at its thinnest.
