Abstract: Disclosed is a sounder module, which comprises a housing for accommodating a vibration system and a magnetic circuit system. The housing is provided with a sound hole which is formed to deviate from the center position of the vibration system and is higher than the surface of the housing. The vibration system comprises a vibrating diaphragm. A dome is provided at one side of the vibrating diaphragm closer to the sound hole. A pressure regulating part is arranged on the dome. The pressure regulating part is higher than other positions of the dome and projects towards the sound hole. The sounder module in the present invention is capable of balancing asymmetrical sound field distribution of the front acoustic cavity, and locally increasing the sound pressure distribution on the surface of the vibrating diaphragm to balance it with other parts, effectively decreasing system polarization, and reducing harmonic distortion.
