Embodiment 1: As shown in Figs. 1 to 6, a novel vibration assembly comprises an outer casing 1, a driving motor 2 and a movable swing arm 3, wherein a housing accommodating cavity 11 is formed inside the outer casing 1, and the driving motor 2 is fixedly mounted in the housing accommodating cavity 11.As shown in Figs. 1 to 6, the movable swing arm 3 has a first end portion 31 and a second end portion 32, the first end portion 31 of the movable swing arm 3 being disposed on the outside of the outer casing 1, the second end portion 32 of the movable swing arm 3 being rotatably hinged to the outer casing 1 and the second end portion 32 of the movable swing arm 3 being disposed in the cavity 11 for housing accommodation.As shown in Figs. 2 to 6, a rotary member 4 is further provided between the drive motor 2 and the second end portion 32 of the movable swing arm 3, the rotary member 4 is connected to the output shaft of the drive motor 2, the surface of the rotary member 4 is provided with a spherical groove 41 toward the movable swing arm 3 side, and the spherical groove 41 is offset from the center of rotation of the rotary member 4.Still further, as shown in FIGS. 2 to 6, the second end portion 32 of the movable swing arm 3 is provided with a long groove 33, and a ball body 5 is provided between the rotating member 4 and the second end portion 32 of the movable swing arm 3, a part of the ball body 5 located on the side of the rotating member 4 is inserted into the spherical groove 41 of the rotating member 4, and a part of the ball body 5 located on the side of the movable swing arm 3 is inserted into the long groove 33. When the novel vibration assembly according to the utility model is actuated, the drive motor 2 is turned on after being connected to the power supply and the drive motor 2 drives the rotary member 4 to rotate. Since the spherical groove 41 is offset from the center of rotation of the rotating member 4 and the ball body 5 is inserted into the spherical groove 41 and the long groove 33 of the movable swing arm 3, respectively, the rotating member 4 vibrates the second end portion 32 of the movable swing arm 3 when rotated by the ball body 5. Since the first end portion 31 and the second end portion 32 of the movable swing arm 3 have a one-piece structure, the first end portion 31 located on the outer side of the outer case 1 also performs a swing motion when the second end portion 32 swings.It should be noted that in the novel swing structure in Embodiment 1, the drive motor 2 vibrates the movable swing arm 3 through the rotating member 4 and the ball body 5. As compared with the prior art, the overall structure of the novel vibration assembly in the embodiment 1 is simpler and more compact.In summary, it can be seen that the novel vibration arrangement in the embodiment 1 offers the advantages of innovative construction, simple structure and compact design.Embodiment 2: As shown in Figs. 3 to 6, the difference between this Embodiment 2 and Embodiment 1 is that the surface of the rotary member 4 toward the movable swing arm 3 side is a concave surface 42 while the second end portion 32 of the movable swing arm 3 is provided with a convex surface 34 protruding toward the rotary member 4 side, a spherical groove 41 is provided on the concave surface 42 and a long groove 33 is provided on the convex surface 34; and the concave surface 42 of the rotary member 4 mates with the convex surface 34 of the movable swing arm 3.With this construction, since the concave surface 42 of the rotary member 4 and the convex surface 34 of the movable swing arm 3 are fitted to each other by a concave-convex fit, the overall structure of the swing assembly can be made more compact. Embodiment 3: As shown in Figs. 2 to 5, the difference between this Embodiment 3 and Embodiment 1 is that the second end portion 32 of the movable swing arm 3 is provided with two coaxial trunnions 35, the left trunnion 35 protruding toward the left side and extending, and the right trunnion 35 protruding toward the right side and extending;wherein the outer casing 1 comprises a left casing 12 and a right casing 13 connected to the left casing 12, wherein the cavity 11 for housing accommodation is collectively surrounded by the left casing 12 and the right casing 13, pivot holes 14 are provided in the left casing 12 and the right casing 13, respectively, and wherein the pivot pins 35 are rotatably fitted into the respective pivot holes 14 on the corresponding side.Note that the left housing 12 is screwed to the right housing 13. When the movable swing arm 3 driven by the drive motor 2 via the rotary member 4 and the ball body 5 swings, the movable swing arm 3 takes the position of the pivot pin 35 as the center of swing.Embodiment 4: As shown in FIGS. 4 to 6, the difference between this Embodiment 4 and Embodiment 1 is that the output shaft of the driving motor 2 is provided with a cruciform driving block 6, and the rotating member 4 is provided with a driving groove 43 opened to the driving motor 2 side and having a cruciform shape, the driving block 6 being embedded in the driving groove 43 of the rotating member 4.By properly connecting the cruciform driving block 6 to the driving groove 43, the novel vibration assembly in the present embodiment 4 can effectively ensure, on the one hand, that the output shaft of the driving motor 2 drives the rotary member 4 to rotate, and, on the other hand, that the convenience of assembly is effectively improved. Embodiment 5: As shown in FIG. 2, the difference between this Embodiment 5 and Embodiment 1 is that a motor slot 111 is provided in the housing accommodating cavity 11 and that the drive motor 2 is snapped and mounted in the motor slot 111.Embodiment 6: As shown in FIGS. 1 and 2, the massage device comprises a novel vibration arrangement as described above.Since the above-mentioned novel vibration assembly offers the advantages of innovative construction, simple structure and compact construction, the massager of the utility model also accordingly has the advantages of innovative construction, simple structure and compact construction.The above content is only the preferred embodiments of the present invention, and the person skilled in the art can make appropriate changes in both the concrete embodiment and the scope of application based on the idea of the present invention.
