N35H Disc Round Magnet for Loudspeaker is a round magnet designed for loudspeakers.
Shape and Size:
N35H Disc Round Magnet for Loudspeaker is a standard round magnet with a moderate diameter to meet the speaker's magnet size requirements. Its regular shape and consistent diameter ensure stability and reliability during installation and use in the speaker. The magnet surface is carefully polished and processed to present a smooth and shiny appearance. This not only enhances the durability of the magnet, but also makes it less susceptible to damage or corrosion during use.
High Magnetic Performance:
N35H Disc Round Magnet is made of high-performance permanent magnetic material, with a magnetic energy product of N35H level and strong magnetic force. This enables it to provide a stable magnetic field in the speaker, ensuring the quality and effect of the sound output.
High Stability:
The magnet has high temperature stability and chemical stability, and can maintain stable magnetism under various harsh environmental conditions. This ensures that the speaker can work normally in various environments and provide excellent sound effects.
Easy to install and use:
Due to its regular round shape and moderate size, N35H Disc Round Magnet is easy to install and use. It can be easily embedded into the magnetic circuit system of the speaker and works well with other components to ensure that the speaker's performance is fully utilized.
Application Fields
N35H Disc Round Magnet is specially designed for speakers and is widely used in various audio equipment. It not only provides a stable magnetic field, but also supports the speaker to produce clear and realistic sound effects.
