Summary:The utility model discloses a miniature loudspeaker, which comprises a dome and a voice coil, the dome comprises a main body, and the main body is provided with an upper convex hull protruding upwards; the voice coil comprises a body, the top surface of the body is connected with the dome, and a part of the upper convex hull crosses the upper part of the body to construct an air flow channel communicating the inner side space and the outer side space of the body. The upper convex hull is arranged on the spherical top, so that the structural strength of the spherical top can be improved, the risk of large-amplitude deformation of the spherical top can be reduced, and an airflow channel for communicating the inner side space and the outer side space of the voice coil body can be constructed, so that airflow exchange between the inner side space and the outer side space of the voice coil becomes smooth, the high-frequency sensitivity of the micro loudspeaker during working is improved, and the service life of th
