Disclosed are a massager and a process for assembling same. The massager comprises a flexible body (110), a box body (120) provided within the flexible body (110) and a PCB board (160) provided within the box body (120). The massager also comprises a flexible housing (130), a button panel (140) inserted from outside the flexible housing (130), and a pressing piece (150) located inside the flexible housing (130) and securely connected to the button panel (140) and sandwiching the housing material of the flexible housing (130) therebetween. The PCB board (160) is securely connected to the inside of the button panel (140) or to the pressing piece (150) and the flexible housing (130) encapsulates the flexible body (110). In the present invention, since the button panel (140) is securely connected to the pressing piece (150) inside the flexible housing (130), the button panel (140) will not dislodge from the flexible housing even if it is kneaded and dragged. At the same time, since the flexible housing (130) encapsulates the flexible body (110) snugly, under the constraint of the flexible housing (130), the PCB board (160) will not dislodge from inside the box body (120) and the box body (120) will also not dislodge from inside the flexible body (110). The massager of the present invention has a simpler structure, the connections thereof are more reliable and is easier to assemble.La présente invention concerne un dispositif masseur et son procédé dassemblage.
