The invention provides a mobile phone speaker cavity device and a sealing method thereof. The mobile phone speaker cavity device comprises an upper shell and a lower shell, and a speaker body; the speaker body is arranged between the upper shell and the lower shell, wherein the lower shell is a box with an opened end, and a box wall of the lower shell is perpendicular to the box bottom; an end surface of the box wall is provided with a circle of groove in a closed loop. The sealing method of the mobile phone speaker cavity comprises four steps. The mobile phone speaker cavity device and sealing method thereof provided by the invention have the advantages as follows: the cavity air leakage caused by the extruded deformation of the sealing foam is prevented; the cost is cheaper in comparison with the ultrasonic sealing mode; the thickness of the mobile phone speaker device is lowered so that the entire mobile phone is thinned; and the structure is simple and the applicability is extensive. 本发明提供了种手机喇叭腔装置及其密封方法，
