Planar Magnetic Speakers
Planar magnetic speakers (
netvoyne.ru) use a flat diaphragm to convert an electrical signal into sound. They are known for accuracy, detail and low distortion. They are able to handle a wide range of frequencies, making them easy to listen to.
Dynamic drivers have more robust and rigid diaphragms than thin and ultra-light ones used in
best planar headphones magnetic speakers. This restricts their ability to move and accelerate quickly, leading to sonic distortion.
They are simple to construct
Many people believe that making planar magnetic speakers is a challenge, but they are extremely easy to build. It is essential to follow the instructions carefully and
Planar Magnetic Speakers build an audio system that is well-engineered. The result will be a high-quality audio system that is able to compete with any model that is commercially available. In addition to being easy to build these speakers offer better sound quality than traditional dynamic drivers. They have superior clarity and a greater dynamic range, and a more controlled directivity which all contribute to a more immersive listening experience.
Planar magnetic speakers emit extremely directional, flat waves, in contrast to conventional loudspeakers which project sound along circular wavefronts. They can reproduce low-frequency sounds, which is not possible with conventional speakers. In addition, their incredibly precise imaging can bring music to life in a way that makes traditional speakers sound slow compared to.
A planar magnetic drive generates sounds by using a thin sheet of metal suspended between two stationary conductive plates. The audio signal is carried by a current through the panel, which rapidly shifts between positive and negative. The magnetic array moves the panel's negative end back and forth and causes the diaphragm of the panel to move. The result is a large sound field with minimal distortion and a high dynamic response.
The maximum excursion of a planar magnet speaker is one of the most important aspects of its performance. It is the maximum distance a speaker can travel before it starts to distort. This is measured at a particular frequency and output level. For instance, if would like to hear a 20 Hz bass note, you will require a speaker that has an excursion of around 1 mm.
A solid planar magnet driver should be able maintain structural integrity while enduring high excursion. It should be able to disperse heat effectively and handle a substantial amount of power. To achieve these requirements, the speaker's voice coil must be with sufficient thickness and size. The voice coil must be wrapped in a conductive material that is capable of conducting electricity.
They effectively disperse heat
This is an important aspect of any speaker, but especially a planar magnetic. The voicecoil is in close contact with the magnet array and has a very high flux density across the gap. This is the reason for heat in a speaker, and it has to be cooled down to avoid damage and distortion. Convection and radiation are two ways in which the voicecoil can get rid of heat. Radiation is the preferred method because it does not have the cone's pumping effect. However, it should be done with careful consideration and the design must manage the power being used.
The first step is to ensure that the gap between the array and the voicecoil is at a minimum of 1mm. This is vital, as any gap that is greater than 1mm can cause some severe distortion. The gap must be large enough for the voicecoil to move freely without hitting the rear plate. The wide gap designs that are popular among manufacturers aren't efficient and only work at low frequencies.
Place a magnet on the gap, and then measure the resistance. The greater resistance, the less heat is dissipated and the more likely it will distort. The lower the resistance is, the more efficient and free of distortion the speaker will be.
planar headphone magnetic speakers are able to reproduce the upper octaves with incredible accuracy, however they can't replicate lower frequencies since they require a large diaphragm. This is the reason why many planar magnetic speakers employ a tweeter and woofer together. This allows them to cover a wider frequency range, with less distortion.
Planar magnetic drivers are known for their low distortion and great bass. This is due to the fact that they are dipoles which means they radiate equal energy front and back using inverted phase. This is an advantage over conventional drivers that can be subjected to mechanical distortion and strong Q resonances.
They can handle a lot of power
Many people are concerned that planar magnetic speakers won't be capable of handling the amount of power that they require however the reality is that they are able to. The "voice coil" has a greater surface area than a dynamic driver, and will therefore be able to disperse more heat. In addition, the diaphragm is thin and light, which helps to reduce distortion levels.
However, it's important to remember that the planar magnetic speaker will still need to be driven by a significant amount of power to create a good sound. They're not able to efficiently disperse energy as a conventional speaker, which means that they are sensitive to the way the room is set up. Additionally, they're directional, which means that listening from a few degrees off-axis can result in the perceived sound level dropping significantly.
Another factor that affects their capacity to handle a large amount of power is the fact that they are inefficient. This is due to the fact that they have a much lower impedance than standard drivers, which means they need more power to maintain the same listening volume. They are also susceptible to magnetic saturation that can cause distortion.
Measuring the maximum excursion of a planar magnetic speaker is a great way to test its capacity to handle high-power. This is the maximum distance that the diaphragm can travel before it begins to distort upon hitting the magnet array. The most powerful planar speakers can reach a maximum distance of 1 mm.
Planar magnetic speakers also offer a greater frequency range than cone drivers. This can be advantageous in certain situations. They can reproduce a greater amount of frequencies, which could enhance the quality of sound effects and music. This can make it easier to distinguish between vocals and instruments in songs.
The most effective planar speakers reproduce a wide range of frequencies, including bass frequency. 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 loudspeakers, but provide a unique immersive experience. These speakers are also great for home theater systems.
They are directed
When an electrical signal is applied to the conductive trace patterns, the magnetic field creates diaphragm movement that produces sound waves. The movement is more precise and controlled in comparison to traditional cone drivers. This allows for an improved frequency response. This allows planar speakers to produce more detail and clarity in the music.
These flat diaphragms 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 and more like traditional dynamic speakers). This flexibility lets designers choose from a variety of options when designing wall or built-in loudspeakers. They can provide outstanding performance at a reasonable price.
The diaphragm of a planar magnetic driver is typically made from a thin, light polymer that is coated with copper circuits that conduct electricity. The diaphragm that is coated with metal is surrounded by arrays of magnets that are arranged in bars with a wide spacing.
