Speaker magnet and the working principle and the definition of a species definition: horn device in the magnets, is the horn magnets, referred to as 'trumpet magnetic. Working principle: the change of current through sound, magnet into the magnet. Current direction changing, magnet wire in the magnetic field force kept back and forth movement, and drive the paper cone vibrating back and forth. The sound came can make a sound. Categories: the horn on the magnets are ordinary ferrite magnets and ndfeb magnet, but general ferrite with more and more common ferrite permanent magnet is mainly used for medium/headset, ndfeb permanent magnets used in high-end headphones, the sound quality is very good, good elasticity, good details, vocal sound quality, sound field positioning accuracy. Magnetic ndfeb horn of main specifications are: & phi; 6*1,φ 6 * 1. 5,φ; 6*5,φ 6. 5 * 1. 5,φ; 6. 5 *φ 2 * 1. 5,φ; 12 * 1. 5,φ; 12. 5 * 1. 2, such as digital units are in millimeters. The specific need according to the speaker the required specifications. Trumpet magnetic coating: dujiangyan is generally choose galvanized, according to the requirements of environmental protection, can carry out environmental protection, such as zinc plating. Magnet knowledge: the shape of the magnet magnet is different, there will be a positive or negative bias in the features, it is mainly set in the magnet size, shape and environmental factors. Cylindrical, rectangular, annular magnets are popular shapes. / dongguan magnet products co. , LTD. , magnets, powerful magnets, profiled magnets, magnet factory, dongguan magnet products co. , LTD
