A vibration device configured to receive electric signals deliverable from a signal unit, the vibration device being for physical treatment usage when attached to a pair of hanging ropes (2, 3) which are intended to extend from a location above the vibration device to transfer vibration from the vibration device down the ropes to a user, comprising: - a vibrator apparatus, comprising a first part and a second part which are mutually movable, co-axially aligned parts, the first part being configured to receive the electric signals, the vibration device further comprising: - a vibration beam (1") to which the vibrator apparatus is attached, wherein rope gripping devices (9, 10) configured to engage the pair of hanging ropes (2, 3) are provided at opposite ends of the vibration beam (1"), wherein - the first part is a coil which is rigidly attached to the vibration beam (1"), the coil being configured to receive said electric signals as at least one of pulsating, sinusoidal and stochastic type signals in combination with pulsating signals or sinusoidal signals, - the second part is a permanent magnet which is suspended by a pair of springy elements (49, 50; 93, 94) attached to said vibration beam (1 "), said vibration beam (1") and said permanent magnet being movable relative to each other, - the coil is a moving coil in interaction with the magnet and the vibrator apparatus constitutes a moving coil mechanism wherein the coil is a moving coil in interaction with the magnet, - the coil and magnet being linearly and coaxially movable relative to each other between extreme positions upon application of said signals to the moving coil, wherein an actual distance of relative movement is a portion of a distance between said extreme positions and is less than an axial length of the moving coil, and - a mass of the magnet and thereby its inertia is substantially larger than a total mass and inertia of the coil and vibration beam (1") combined, so that upon application of said signals to the coil, the coil and the vibration beam (1") will move more easily than the magnet and cause the vibration beam (1") and the coil to vibrate relative to the magnet, thereby causing vibration of said rope gripping devices (9, 10). - a vibrator apparatus, comprising a first part and a second part which are mutually movable, co-axially aligned parts, the first part being configured to receive the electric signals, - a vibration beam (1") to which the vibrator apparatus is attached, wherein rope gripping devices (9, 10) configured to engage the pair of hanging ropes (2, 3) are provided at opposite ends of the vibration beam (1"), wherein - the first part is a coil which is rigidly attached to the vibration beam (1"), the coil being configured to receive said electric signals as at least one of pulsating, sinusoidal and stochastic type signals in combination with pulsating signals or sinusoidal signals, - the second part is a permanent magnet which is suspended by a pair of springy elements (49, 50; 93, 94) attached to said vibration beam (1 "), said vibration beam (1") and said permanent magnet being movable relative to each other, - the coil is a moving coil in interaction with the magnet and the vibrator apparatus constitutes a moving coil mechanism wherein the coil is a moving coil in interaction with the magnet, - the coil and magnet being linearly and coaxially movable relative to each other between extreme positions upon application of said signals to the moving coil, wherein an actual distance of relative movement is a portion of a distance between said extreme positions and is less than an axial length of the moving coil, and - a mass of the magnet and thereby its inertia is substantially larger than a total mass and inertia of the coil and vibration beam (1") combined, so that upon application of said signals to the coil, the coil and the vibration beam (1") will move more easily than the magnet and cause the vibration beam (1") and the coil to vibrate relative to the magnet, thereby causing vibration of said rope gripping devices (9, 10). - the first part is a coil which is rigidly attached to the vibration beam (1"), the coil being configured to receive said electric signals as at least one of pulsating, sinusoidal and stochastic type signals in combination with pulsating signals or sinusoidal signals, - the second part is a permanent magnet which is suspended by a pair of springy elements (49, 50; 93, 94) attached to said vibration beam (1 "), said vibration beam (1") and said permanent magnet being movable relative to each other, - the coil is a moving coil in interaction with the magnet and the vibrator apparatus constitutes a moving coil mechanism wherein the coil is a moving coil in interaction with the magnet, - the coil and magnet being linearly and coaxially movable relative to each other between extreme positions upon application of said signals to the moving coil, wherein an actual distance of relative movement is a portion of a distance between said extreme positions and is less than an axial length of the moving coil, and - a mass of the magnet and thereby its inertia is substantially larger than a total mass and inertia of the coil and vibration beam (1") combined, so that upon application of said signals to the coil, the coil and the vibration beam (1") will move more easily than the magnet and cause the vibration beam (1") and the coil to vibrate relative to the magnet, thereby causing vibration of said rope gripping devices (9, 10).
