A loudspeaker includes an outer frame with an annular magnet partially exposed from a bottom thereof; a voice coil located inside the annular magnet; a diaphragm glued to between an expanded front opening of the outer frame and the voice coil; a flexible suspension ring having an outer edge fixed to a stepped section of the outer frame and a central opening edge clearance-fitted to a middle/front portion of the annular magnet; and an inner frame having a front portion fitted around the voice coil, a rear portion located on the central opening edge of the flexible suspension ring, and legs extended between the front and rear portions to locate in front of slots formed on the annular magnet. Therefore, the loudspeaker has reduced depth and volume, increased vibration amplitude and stability, and high quality sound output.
