How Do Magnet Planar Headphones Work?

If you've never tried a pair of headphones with magnetic drivers that planar, it may be difficult to wrap your mind around how they work. Planar magnetic drivers make use of two flat magnets which are sandwiched in thin diaphragms with conductors. This differs from the voicecoil actuator which drives a stiff cone back and forth.

Diaphragm

In contrast to a traditional dynamic headphone driver with dome or cone-shaped diaphragms, a magnet planar has a flat piece of flexible film. The film is dotted with conductors on it, which react with magnets that are placed on either side of the diaphragm. The diaphragm moves and reacts when the magnetic field generated by these magnets is triggered by the electrical signal that runs through the wires. This causes soundwaves that you can then hear.

The diaphragm in the human body is a dome-shaped muscle membrane that separates the thoracic (chest) and abdominal cavities. It is the main muscle of respiration and is involved in the process of inspiratory action (exhaling air), such as breathing or coughing, sneezing crying, laughing, vomiting, Magnet Planar and parturition. The diaphragm plays part in expulsive actions like urination, defecating and pushing out the fetus during delivery.

A planar magnetic diaphragm is much more sensitive to changes in audio signals than dynamic drivers due to its ultra-lightweight and thinness. Planar magnetic headphones have a more delicate, precise sound than dynamic drivers.

One of the downsides of planar magnetic headphones is that, at higher volume, they can leak more than their dynamic counterparts. This is due to the motion of the diaphragm inside a planar magnetic headphone causes a portion of the audio to be pushed outwards and towards the listener.

It is not a big issue if you are using headphones only in quiet environments, or to watch movies. However, it can be annoying for active listening or public usage. There are several options that can reduce the amount of leakage. They include the Audeze LCD-4 and HiFiMAN Sundara. Wisdom Audio, for example is a leader in the development of PMD technology. They have worked hard to resolve issues that arise with this type of headphone. They have invented numerous innovations that you can see on their products. For instance, their latest flex circuit-based planar winding overcomes the limitations of stamped copper windings and gives an improved utilization rate.

The Conductors

Conductors connect the diaphragm and the magnets and are responsible for producing the sound that you hear. They are typically made from a mixture of aluminum and copper. The diaphragm is then wrapped around the central magnetic core. This is supported by the headphone's frame. The magnetic core is a circular form of magnetic element and can be made from any material, however it is usually made by using Neodymium. The core itself is the primary component of any planar audio driver. It is made up of several nested layers of an helix that is circular with an area of 10-20mm.

Planar magnetic drivers have the benefit of a larger soundstage compared to their more dynamic counterparts. This is because the entire diaphragm vibrates when an audio signal is received, instead of just a small area that is attached to the voice coil. The larger surface area results in lower distortion levels, particularly when the volume is greater.

The ability of a magnet planar to quickly react to changes in the audio signals is a crucial characteristic. This allows it to reproduce a wide range of frequencies and produces an even more realistic and detailed sound. This is a fantastic feature for those who appreciate music that includes a variety of instruments and vocals.

The stacking design of planar magnetics reduces the variation between parts, making them ideal for critical applications that require a high reliability. They offer better consistency and lower distortion in the magnetic field when compared to traditional wirewound magnets. This is essential for the efficiency of electronic devices.

The Magnets

A magnet is a substance with magnetic properties. It can create an attractive or a repulsive force on certain materials, such as nickel, iron, cobalt and a few steels. It also attracts and repel certain electrical conductors. This phenomenon is referred to as magnetism. It can be created through electromagnets, permanent, or temporary magnets. Magnets are employed in a variety of applications, such as electronic devices like headphones, mobile phones and laptop computers.

In contrast to traditional balanced armature and dynamic drivers, which push a stiff diaphragm with a voice coil, planar magnetic driver technology makes use of a thin, light and flexible diaphragm that vibrates to create an unidirectional sound wavefront rather than the focused spherical wavefront found in many headphones and speakers. This creates a much cleaner and more spacious soundstage, and is recognized for its rich bass.

The biggest drawback of planar headphone drivers is that the large magnets they hold require lots of power. This makes them more heavy and bulkier than other types of headphone drivers. This is why many planar magnetic drivers require a special power amplifier in order to function properly.

The amplifier should be designed to match the power output of a planar magnetic driver in order to give the best listening experience. The amplifier must also have a high input impedance to allow it to drive the planar magnet driver to its maximum output.

The planar magnetic driver is generally constructed to be dipole (radiating equally and in a different phase in front and behind the speaker, as ESLs do) or a monopole (radiating only in the direction of the forward and more like traditional headphones). The most common design of a planar magnetic driver is a bipole, with two poles that alternate on the north and south. Its shape makes it easy to build as a single piece of steel and is very efficient at creating a strong field in the center of the faceplate.

Planar magnetic drivers are more efficient and have a lower distortion due to their size. They are utilized in high-end headphone systems where sonic precision is important. They are also used in audio equipment that is designed for professional use, like microphones and loudspeakers. They are also perfect for medical imaging, and other sensitive applications that require high-precision.

The Seal

To perform well Planar drivers must be sealed extremely well and precisely. A tiny leak can drastically impact sound quality and cause distortion. It takes much effort to make the perfect seal for a planar driver.

Unlike many conventional headphone designs the planar magnetic headphones should not have any gaps within the enclosure of the acoustic. This is because gaps can cause the diaphragm's resonance with multiple frequencies simultaneously. This is known as crosstalk, and it can cause the audio quality to suffer greatly.

The most commonly used seal for planar magnetic headphones is the rubber rings seal. This seal is able to stop air leaks extremely effectively. It is also extremely robust and can last for a long time. It is important to remember that this type seal can occasionally produce an unnatural sound. It is therefore crucial to choose a high-quality rubber seal if you're planning on using the planar magnetic headphone.

Another alternative to an in-plane magnetic driver is the liquid crystal display (LCD) seal. It is a specialized seal that is designed to stop gaps from forming. It's also designed to withstand a large amount of pressure. This makes it a good choice for audiophiles who are looking for a premium audio quality.

One advantage of LCD headphones is that they provide a very clear and detailed sound. This is particularly the case for headphones that are high-end, like the Audeze LCD-4 and HiFiMAN Susvara. It is possible to find LCD planars headphones with the same audio quality at a lower cost.

It is also important to remember that a planar magnetic headphone can generate a greater sound pressure than standard dynamic headphones. The way they are built is the reason for this. In contrast to dynamic headphones, planar magnetic headphones have two magnets that push on the diaphragm. This can create a strong force that can produce extremely high frequencies.

Planar magnetic drivers, which are a relatively new technology on the headphone market are a revolutionary product. They have already begun to revolutionize how people listen to music. These headphones offer high-quality sound and are comfortable to wear. They are also easy to adjust.
