Disclosed is a miniature loudspeaker, relating to the technical field of electroacoustic products, and comprising a magnetic circuit system, a vibration system and a support system. The magnetic circuit system comprises a basin frame, and a magnet and a washer accommodated within the basin frame. The vibration system comprises a diaphragm and a voice coil adhesively fixed to the diaphragm. The support system comprises a front cover, and a casing matched and combined with the front cover. The casing comprises a bottom wall and a side wall. The bottom wall is provided with a mounting portion accommodating the magnetic circuit system, and is also provided with an assembly plane for assembly with a terminal. Positions of the bottom wall and the side wall corresponding to the assembly plane are provided with a height difference, and matching forms an avoidance inclined surface. Sound holes are arranged on the bottom wall, and opening ends of the sound holes are located on the avoidance inclined surface. The miniature loudspeaker solves the technical problem that sound holes are easily blocked when overall machine assembly is performed with a terminal device, and the arrangement of sound holes having bottom surfaces which are inclined surfaces enables air to exit from side surfaces, thereby preventing an installation test curve from being affected. |
