PROBLEM TO BE SOLVED: To construct an oscillation generating system of a bone conduction theory.SOLUTION: In an oscillation generating system, an oscillator 1 having a movable portion 3 is placed directly or via a fixture or the like on a body 2 which is entirely made from the same raw material and whose property is the same at any portion. Similarly, the movable portion 3 of the oscillator 1 is mediated by a spring 4 or an elastic body in series in between to be connected directly or via a fixture 5 or the like to a place on the body 2 that is different from a place where the oscillator 1 is connected and placed. The movable portion 3 of the oscillator 1 operates by obtaining a resonance action of the spring 4 or the elastic body, and is used for bringing an object to be subjected to oscillation into contact with the body 2. |
