Loudspeaker

The invention belongs to the technical field of loudspeakers, and discloses a loudspeaker which comprises a shell, a vibration structure, a magnetic circuit structure and a voice coil, a containing cavity is formed in the shell, one end, in the first direction, of the containing cavity is communicated with the outside through a sound production port, the other end of the containing cavity is connected with the outside through a bearing port, and the vibration structure is arranged at the sound production port. The magnetic circuit structure comprises a yoke and a magnetic pole structure arranged on the yoke, the yoke is erected at the bearing port in a suspended mode, the two ends of the yoke in the second direction are connected to the shell respectively, the second direction is perpendicular to the first direction, and the voice coil is connected to the vibration structure and can move in the first direction relative to the magnetic circuit structure. According to the loudspeaker, the yoke in the magnetic c
