FIELD: physics, radio engineering.
SUBSTANCE: proposed micro loudspeaker consists of casing, ring, oscillating film, coil, magnet, magnetic core and p.c.b. The aforesaid casing governs micro loudspeaker shape. Ring seats inside the casing. Ring supports oscillating film that accommodates the coil. Magnet is arranged on the ring. Magnetic core accommodates p.c.b. Bent inward section is located nearby p.c.b. or ring, right on the casing edge, to clamp p.c.b. or ring.
EFFECT: reduced amount of adhesive required for assembly, higher quality.
