Micro-movable coil electroacoustic transducer

The utility model discloses a micro-movable coil electroacoustic transducer which comprises a magnetic circuit system, a vibration system and an encapsulation system fixedly wrapped with the magnetic circuit system and the vibration system. The encapsulation system comprises a housing, a vibration system support part fixed at the periphery of the housing, and a front cover covered on the support part; the support part, the housing and the front cover form a sound aperture at the periphery of the micro-movable coil electroacoustic transducer; and the sound channel of the sound aperture adopts a bending shape. The sound aperture formed by the housing, the support part and the front cover is formed on the side wall of the micro-movable coil electroacoustic transducer, thereby enlarging the accommodating space for the magnetic circuit system, especially for the magnet; the increase of the magnet can improve the magnetic flux and a driving force of the micro-electroacoustic transition unit, thereby increasing the sensibility of the micro-movable coil electroacoustic transducer, eliminating the requirement for extra damping bonding, improving the acoustic behavior of the micro-movable coil electroacoustic transducer, and reducing the cost.
