The invention discloses a miniature receiver, and belongs to the technical field of loudspeakers. The miniature receiver comprises a shell, a vibration system and a magnetic circuit system. the vibration system and the magnetic circuit system are both arranged in the shell, the vibration system comprises a voice diaphragm, a voice coil and a supporting assembly, the voice diaphragm abuts against the top end of the voice coil, the supporting assembly is connected to the voice diaphragm and used for elastically supporting the voice diaphragm, and the magnetic circuit system is configured to drive the voice coil to move in a reciprocating mode, so that the voice coil drives the voice diaphragm to move to generate sound. In addition, an air coupling cavity used for sounding is formed among thevibration system, the magnetic circuit system and the inner wall of the shell. Under the action of the supporting assembly, the vibration amplitude of the voice coil is increased, the vibration amplitude of the voice diaphragm is increased, the sound source level of the telephone receiver is improved, and the sound pressure can be radiated outwards more efficiently through the formed air couplingcavity, so that the sound source level of the telephone receiver is improved.
