Abstract

The invention discloses an array-type magnetic circuit. A plurality of groups of magnets are arranged in a conventional magnetic conductive support to form a magnetic field forming part in a manner of various combinations; magnetic clearances used for putting coils are reserved among the magnets; the magnetic circuit has the common characters that the polarities of the magnets on both sides of the same magnetic clearance are arranged in the same direction, and opposite to the polarities of the magnets on both sides of the other magnetic clearance, so as to ensure that driving forces of magnetic force lines generated by a plurality of groups of magnets to the coils in the magnetic clearances are superposed in the same direction. The invention further discloses a transducer of an array-typemagnetic circuit made by adopting the magnetic circuit; a coil and a vibrating membrane in the transducer can be connected in a parallel manner or a perpendicular manner, and is matched with the magnetic circuit. The magnetic circuit and the transducer have the advantages of low energy consumption, high efficiency, small distortion and compact structure; furthermore, the magnetic circuit and the transducer can be made into various shapes that are particularly suitable for long-narrow or gap-shaped structures, and include various fields such as communication and, broadcast fields.

Description

technical field [0001] The invention relates to the design of miniature, long and narrow and special-shaped electric magnetic circuit and the electromechanical sound transducer prepared by using the magnetic circuit. Background technique [0002] There are two types of traditional miniature electric magnetic circuits: internal magnetic circuit and external magnetic circuit. Internal magnetic circuit such as figure 1 As shown, the magnetic field lines emitted by the N pole of the cylindrical magnet 2 pass through the magnetic plate (pole chip) 3 close to the N pole of the cylindrical magnet 2, pass through the magnetic gap g1 and the magnetic gap g2, and reach the magnetic conductive bowl 1 Returning to the S pole of the magnet 2, a complete magnetic circuit is formed. [0003] External magnetic circuit such as figure 2 As shown, the magnetic field lines emitted by the N pole of the ring magnet 6 pass through the field core 5 of the T iron, pass through the magnetic gap g...
