Description : Plastic-bonded magnets are particle composites with permanent-magnet powder embedded in a plastic binder. Hard ferrite (HF), various SmCo and NdFeB powders and, to a very little extent, AINiCo alloys are used as magnetic powder. For embedding the magnetic particles, thermoplastic binders as, for instance, polyamide (PA) or polyphenyl sulfide (PPS) and duroplasts like epoxy resins are used. Depending on the material composition and production process, isotropic and anisotropic magnets with differing magnetic and mechanical specifications are available. Since not only the type of magnet or plastic material, but the filling and alignment degree, too, determine the composite`s properties, the outcome is widely varying magnetic parameters and an outstanding variety in types and shapes.
Halbach array is a special arrangement of permanent magnets that augments the magnetic field on one side of the array while cancelling the field to near zero on the other side.[1] This is achieved by having a spatially rotating pattern of magnetisation. The rotating pattern of permanent magnets (on the front face; on the left, up, right, down) can be continued indefinitely and have the same effect. The effect of this arrangement is roughly similar to many horseshoe magnets placed adjacent to each other, with similar poles touching.
We have strong sintered AlNiCo permanent magnet production scale, can produce the performance of Alnico2-8 grades. And annual output nearly 800 tons. AlNiCo magnet is suitable for producing complex, light, thin, and small products, and is widely used in instrumentation, communications, magnetoelectric switches, and various sensors. AlNiCo products are mainly used in automotive parts, instrumentation, electroacoustics, motors, nuclear power, teaching, aerospace and other fields. It has the characteristics of low temperature coefficient, high temperature resistance, humidity resistance, not easy to oxidize and good working stability.

Headphones are a pair of small loudspeakers that are designed to be held in place close to a user's ears. They are also known as earspeakers, earphones or colloquially, cans. The alternate in-ear versions are known as or earbuds but also can be referred to as earphones. In the context of telecommunication, a headset is a combination of headphone and microphone. Headphones either have wires for connection to a signal source such as an autio amplifier, radio, cd player, portable media player, mobile phone, electronic musical instrument, or have a wireless receiver, which is used to pick up signal without using a cable.
