Planar Magnetic Speakers Planar magnetic speakers convert electrical signals to sound with a flat diaphragm. They are well-known for their precision and clarity, as well as low distortion. They have a wide range of frequencies, making them easy to listen to. The diaphragms of dynamic drivers are much stiffer and heavier than those used in planar magnet speakers. This hinders their ability for them to move and accelerate quickly and can cause distortion in the sound. These are simple to construct Many people think that building planar magnetic speakers is a challenge, but they are actually very easy to make. The trick is to follow the steps and build a well-engineered speaker. The result will be a top-quality audio system that is able to compete with any available model. Planar magnetic speakers are simple to build and offer a superior sound quality compared to traditional dynamic drivers. They have superior clarity, a wider dynamic range and controlled direction which all make for an experience that is more immersive. Unlike conventional loudspeakers, which project sound in circular wave fronts Planar magnetic speakers emit flat waves that are directional. They can reproduce low-frequency sounds, which is difficult to reproduce with conventional speakers. Their extremely precise imaging brings the music to life, making standard speakers sound slow in comparison. To produce a sound, a planar driver utilizes a thin film of metal suspended between two conductive plates. The audio signal is transmitted as an electric current to the panel, which rapidly switches between positives and negatives. The magnetic array is able to move the panel's negative end back and forth and causes the diaphragm to vibrate. The result is a superb dynamic response and a large soundfield, with no distortion. The maximum range of an excursion for a planar magnet speaker is among the most crucial aspects of its performance. This is the maximum distance a speaker can travel before it starts to distort. This is measured at a certain frequency and output level. For example, if you would like to hear a 20 Hz bass note, you'll need a speaker with an excursion of around 1 mm. A reliable planar magnetic driver must be able to endure high excursion and still maintain its structural integrity. It must also be able to effectively disperse heat and manage the rigors of a large power. The voice coil of the speaker should be large and thick enough to meet these specifications. The voice coil should be wrapped in a conductive material that is capable of conducting electricity. They efficiently disperse heat. This is an essential aspect of any speaker, and especially a planar magnetic. The voicecoil is close to the magnet array, and has a high flux density in the gap. Heat is generated by the voicecoil, and it must be eliminated to prevent distortion and damage. Convection and radiation are two ways that the voicecoil can get rid of heat. Radiation is preferred since it doesn't have the convection's pumping effects. However, it should be done with careful consideration and the design must handle the power applied. The first step is to ensure that the gap between the array and the voicecoil is a minimum of 1mm. This is important, as a gap larger than 1mm could cause significant distortion. The gap should be large enough for the voicecoil to move freely without hitting the rear plate. For this reason, the wide gap designs favoured by many manufacturers are inefficient and will only work well at low frequencies. Place a magnet on the gap, and then measure the resistance. The higher the resistance the less heat will be dissipated and the greater the risk of distortion. The lower the resistance the more efficient the speaker will be and the less distortion it can cause. Planar magnetic speakers are able to reproduce the upper octaves of sound with incredible accuracy, however they can't reproduce the lower frequencies because they require a large diaphragm. A majority of planar magnetic speakers include an woofer and a tweeter. This allows them to cover an extended frequency range while causing less distortion. Planar magnetic drivers are known for their low distortion and high bass. The dipole design makes they emit equal amounts of energy in both directions, with an inverted phase. This is a major advantage over conventional drivers which can be subject to mechanical distortion and strong Q resonances. They can handle a huge deal of power Many people are concerned that planar magnetic speakers will not be capable of handling the amount of power that they need, but the truth is that they do. The “voice coil” has a larger surface area than a dynamic driver, and will therefore be able to disperse more heat. In addition the diaphragm is slender and lightweight, which helps to reduce distortion levels. It is important to remember that an acoustic speaker planar will require to be driven by a lot of power to create a excellent sound. They are sensitive to the way a room is set up since they aren't able to disperse their energy as a traditional speaker. Additionally, they're directed, which means that listening from just a few degrees off the axis could result in the sound level dropping significantly. Inefficiency is another aspect that makes them able to handle large amounts of power. They have lower impedances and therefore require more power to achieve the same volume. They are also prone to magnetic saturation, which can cause distortion. An excellent way to determine the capability of a planar magnetic speaker to take on lots of power is to measure its maximum excursion. This is the length the diaphragm will travel before it hits the magnet array and begins to distort. The best planar magnetic speakers can cover a distance of about 1 millimeters before this happens. best magnetic planar headphones can also offer a higher frequency response than traditional cone drivers, which could be beneficial in certain situations. They can reproduce a higher amount of frequencies, which can enhance the quality of sound effects and music. This can help to make it easier to distinguish the different instruments and vocals that are part of a song. The most effective planar speakers reproduce a wide range of frequencies, including bass frequencies. This is an excellent benefit for people who want to listen to music in various settings. These speakers are more expensive than traditional speakers, but provide a unique immersive experience. They are also a good choice for home theater systems. The direction of the arrow is vital When an electrical signal is placed to the conductive trace patterns, the magnetic field creates the diaphragm to move, which generates sound waves. The movement is much more precise and controlled than traditional cone drivers, which allows for a greater frequency response. This lets planar speakers reproduce more clarity and detail the music. These diaphragms with flat sides can be designed to be dipole (radiating equally in front and back like electrostatics and Maggies) or Monopole (radiating only in the forward direction similar to conventional dynamic speakers). This flexibility lets designers choose from a wide 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 generally made from an ultra-thin, light polymer that is coated with a circuit made of copper that conducts electricity. The diaphragm is enclosed by magnets in bars that are widely separated. These magnets create a strong magnetic field that attracts and disperse the diaphragm's air particles. The magnetic fields can also help to radiate heat away from the speaker without creating any strain to the voice coil. Planar magnetic speakers have greater sensitivity than cone speakers that are conventional and can handle large amounts of power without overheating. They also have lower impedance, meaning they require less amplification to reach the same levels of listening. They can reproduce a broad range of audio frequencies, including bass and highs. They are often augmented with woofers boxed to reproduce low frequencies with greater precision. A disadvantage of single-ended planar magnetic loudspeakers is that they have poor damping. This can lead high-Q resonances in the low frequency range of the speaker response, which may color the sound. The solution is a hybrid design which combines the advantages of dipole and planar technology. One of the most important elements that determine the performance of a planar magnetic speaker is its positioning in a room. This can affect a variety of aspects of sound, such as bass response, imaging, soundstage depth and breadth. Toe-in can adversely affect the midrange and the higher frequencies. The ideal speaker will be placed in the area where the central image is at its most narrow.
