Planar Magnetic Technology for Headphones
Planar magnetic technology is being revived by a handful of specialized HiFi audio companies. These companies make headphones using old-school planar drivers that deliver an impressive sound quality.
This paper analyzes the core characteristics of a planar magnet device by examining winding inductance, leakage capacitance and winding conduction losses. A method is also suggested to reduce the parasitic elements.
Low vertical height or low profile
Planar magnetics are more efficient and have a lower profile than wire-wound magnetics. It also minimizes leakage inductance and parasitic capacitance. This allows for a smaller size core to be employed, which reduces the cost of the device. It also doesn't require the magnets to be clamped. This makes it suitable for use in power electronics devices.
Another advantage of planar magnetic technology is that it is lighter and more compact than traditional headphones. It is also able to handle higher frequencies without distortion. This is due to the diaphragm, which is flat, that is employed in these devices, which is usually made of a thin film and is fitted with a conductor trace it. The film is able to react quickly to audio signals, and produce high sound pressure levels.
This means that the audio produced by these devices is more pronounced and clear. This is the reason why it is highly favored by audiophiles, especially those who prefer listening to music in their home or office. It is crucial to remember that a planar magnet driver requires a power amplifier and digital audio converter to perform correctly.
The resultant sound is more natural and precise than the sound produced by dynamic drivers. Planar magnetic drivers are also able to respond to changes in audio signals faster, making them perfect for listening fast music.
Despite their benefits they have some disadvantages. One of these is their cost that can be attributed to the huge amount of magnetic material required to run. Their size and weight can be a hindrance, especially when they are being used as portable devices.
Wide band gap (WBG), devices
Wide band gap (WBG) semiconductors are a type of material that have better electrical properties than conventional silicon-based devices. They can withstand higher voltages and current densities. They are therefore perfect for optoelectronics as well as power electronics applications. Wide band gap semiconductors such as silicon carbide and gallium nitride can provide significant enhancements in terms of performance, size, and cost. They are also more eco green than conventional silicon-based devices. These characteristics make them appealing to satellite and aerospace companies.
Planar magnetic drivers operate using the same principles as dynamic drivers. Conductors of electricity move between two magnets that are fixed when audio signals are passed through them. Planar magnetic drivers, however, employ an array of conductors encased or attached to a thin diaphragm-like film instead of coils. Conductors are a set of coils' that are placed on the diaphragm, and are placed directly between two magnets. This creates the push/pull effect that causes the diaphragm movement.
This technology produces music without distortion and produces a distinctive and pleasing sound. The even distribution of magnetic force over the entire surface of the driver and the absence of a coil behind the diaphragm cause it to move evenly and quickly, producing a highly detailed, accurate sound. The resulting sound is known as isodynamic, orthodynamic, or magnetically-incident.
Generally, headphones that have magnetic drivers that are planar cost more than other technologies due to their complexity and the higher cost. However, there are a number of excellent, affordable alternatives such as the Rinko by Seeaudio and S12 Z12 by LETSHUOER which have recently been released.
Power electronics
Planar magnetics dissipate heat more efficiently than traditional wire wound components. This lets them handle more power without creating excessive strain or audible strain. This makes them ideal for use in headphones. Planar magnetics are more efficient and also provide a greater power density. The technology is especially suitable to applications such as rapid charging of electric vehicles as well as battery management and military systems.
As opposed to dynamic driver headphones which utilize a diaphragm suspended by a voice coil, planar magnetic drivers operate using a different method. When an electromagnetic signal is transmitted through the array and the magnets on the opposite side of the diaphragm are pushed together, a push-pull effect is created. This generates sound waves which move the diaphragm producing audio.
Planar magnetic devices are more efficient than conventional magnetics because they have a higher surface-to-volume ratio. This means they can disperse more heat, allowing them to operate at higher frequencies of switching without exceeding their maximum temperature ratings. They also have lower thermal sensitivity than wire-wound devices, which means they can be used in smaller power electronic circuits.
To maximize the performance of a planar boost inductor, designers should be aware of several aspects, such as core design winding configuration, losses estimation, and thermal modeling. In the ideal scenario, the inductor will have low leakage inductance and winding capacitance, and be simple to integrate into a PCB. Moreover, it should be able to handle high currents and should be tiny size.
In addition, the inductor should be compatible with a multilayer PCB with SMD or through-hole packages. Additionally, the copper thickness needs be sufficiently thin to limit eddy currents in the layers and prevent thermal coupling between conductors.
Flexible circuit-based planar winding
In planar magnetics, flex-circuit-based windings can be used to create an efficient resonance. They are constructed using one-patterned dielectric film and an individual-patterned copper foil. The most popular choice is copper foil, which has excellent electrical properties and is processed to allow termination features on both sides. The conductors on a flex circuit are connected by thin lines that extend beyond the edges of the substrate, providing the flexibility needed for tape automated bonding (TAB). Single-sided flexes are available in many different thicknesses and conductive finishes.
In a typical planar headphones, the diaphragm is set between two permanent magnets which vibrate in response to electric signals that are sent by your audio device. The magnetic fields create the soundwave that runs across the entire surface of diaphragm. This piston-like motion stops breakups and distortion.
Planar magnetic headphones are able to reproduce a broad range of frequencies, notably at lower frequencies. This is because they can produce a larger surface area than conventional cone-type drivers, allowing them to move more air. Additionally, they can reproduce bass sounds with a much higher clarity and clarity.
However they are expensive to produce and require a powered amplifier and DAC to perform correctly. They are also larger and heavier than conventional drivers making them difficult to transport. Their low impedance requires more power to drive, which can quickly add up when you listen to music at a high volume.
Stamped copper winding
Utilizing stamped copper windings in planar magnetic technology can increase the window's utilization ratio and cut down on manufacturing costs. The technique works by placing grooves on the coil body that ensure a layer-accurate placement of the windings. This method helps prevent deformations in the coil and improves the tolerances. It also reduces the amount of scrap created during production and improves quality assurance. This type of closed-back planar magnetic headphones coil is often employed in relay and contactor coils, ignition coils and planar magnetic technology small transformers. It is also utilized in devices that have wire thicknesses up to 0.05mm. The process of stamping produces a uniform winding with high current density. It also ensures that the windings are perfectly positioned on the coil body.
Planar magnetic headphones, unlike traditional dynamic drivers that use a voicecoil conductor in the diaphragm's thin layer, have an array of conductors that are flat directly applied to the diaphragm's thin surface. When electronic signals are applied, the conductors vibrate, creating a pistonic motion that creates sound. Planar magnetic headphones produce a superior sound quality compared to other types of audio drivers.
In addition to reducing weight and costs in addition, this technology has the potential to increase the frequency range of planar magnetic transducers. This is crucial since it lets them operate in a much wider frequency range. Furthermore, it lowers the power requirements of the driver.
However, there are a few disadvantages of this new technology. It is difficult to create a thin-film diaphragm that can withstand the extreme temperatures required for this technology. Manufacturers like Wisdom Audio have overcome the problem by creating a solution that is not adhesive and is able to withstand temperatures as high as 725 degF. This allows them to produce audio of superior quality without compromising durability and longevity.
