The vibration producing device includes a driving shaft being placed under slight rapid vibratory movements in its axial direction, a slight rapid vibratory movements producing member coupled with one end of the driving shaft for causing the driving shaft to be vibrated with the slight rapid vibratory movements, a casing for supporting at least either the driving shaft or the slight rapid vibratory movement producing member in such a manner that the driving shaft can be vibrated with the slight rapid vibratory movements in its axial direction, and a weight member to be coupled with the driving shaft in order to permit the weight member to move in its axial direction under the slight rapid vibratory movements of the driving shaft, wherein the casing is vibrated by allowing the weight member to be moved forwards and backwards alternately along the driving shaft in its axial direction.

Vibration producing device as well as electronic device and human body fitting article both employing such vibration producing device

A linear driving device includes a slight rapid vibratory movements producing member coupled with one end of a driving shaft which causes said driving shaft to be moved in said an axial direction, a casing for supporting at least either said driving shaft or said slight rapid vibratory movements producing member so that said driving shaft can be moved in said axial direction; and a moving body to be coupled with said driving shaft so that said moving body can be moved in the axial direction. When said moving body moves from one end side toward the other end side of said driving shaft, a part of said moving body which forms the surface facing the other end side opposite to said one end of said moving body may hit against a component which stops said moving body from moving further toward the other end side of said driving shaft.
