This creation provides a kind of message structure, includes a pedestal, an electromagnet and a lid. The electromagnet sets the what pedestal, the electromagnet includes a coil and a hollow soft iron, the coil is arranged the hollow soft iron, when the coil is powered, the hollow soft iron can protrude out mobile relative to the pedestal and generate massage effect, the lid removably sets the what pedestal, which is equipped with a perforation protruded out for the hollow soft iron; Thereby, user can change whole height using installing or dismantling lid, to adjust the distance length that hollow soft iron apparent surface protrudes out, and then reach the effect of changing massage effect.本創作提供一種按摩結構,包含一座體、一電磁鐵及一蓋體。該電磁鐵設於該座體,該電磁鐵包含一線圈及一空心軟鐵,該線圈套設該空心軟鐵,該線圈通電時,該空心軟鐵可相對該座體凸伸移動而產生按摩效果,該蓋體可拆卸地設於該座體,該蓋體設有一供該空心軟鐵凸伸之穿孔;藉此,使用者能利用裝設或拆卸蓋體來改變整體高度,來調整空心軟鐵相對表面所凸伸之距離長度,進而達到改變按摩效果之功效。
