Abstract
Disclosed is a miniature moving-coil speaker comprising a magnetic circuit system, a vibration system, and an auxiliary system for fixing the magnetic circuit system and the vibration system. The vibration system comprises a diaphragm and a voice coil integrated with the diaphragm. The auxiliary system comprises a plastic enclosure. The diaphragm is installed correspondingly at one end face of the enclosure, while the magnetic circuit system is installed at the other end face of the enclosure opposite the diaphragm; also: a flexible circuit board is arranged on the end face of the enclosure where the magnetic circuit system is installed, and the voice coil is electrically connected to the flexible circuit board. The design reduces product installation height, while at the same time facilitates wire-leading and wire-combing for the miniature moving-coil speaker, and simplifies product design.
