Abstract

The invention provides an oscillation generating device capable of allowing oscillation operation of an oscillator to be stabled. The oscillation generating device comprises: a housing 10; an oscillator 20 that is housed in the housing 10; an elastic supporting part 40 that oscillatably supports the oscillator 20 along with a first direction and a second direction; and a magnetic driving part 50 that drives the oscillator 20 by using a magnetic force along with the first direction and the second direction. The magnetic driving part 50 is an oscillation generating device 1 having: first magnetic field generating means that is arranged in the side of oscillator 20; and second magnetic field generation means that is arranged in the side of housing 10 so as to be positioned on an extended lineof the oscillator 20 in a third direction crossing to the first direction and the second direction. The elastic supporting part 40 is constructed by a plate spring to which a plurality of folding parts that is folded so that a fold line is along with the third direction and a flat part extending toward the other one folding part from one of the plurality of folding parts.

Description

technical field [0001] The present invention relates to a vibration generating device, and more particularly to a vibration generating device including a vibrating body vibratingly supported by a housing via an elastic support member. Background technique [0002] Currently, vibration generating devices mounted on electronic devices such as portable information terminals and game machines are put into practical use. Vibration used in etc. [0003] As a conventional vibration generating device used for such an application, for example, there is a structure disclosed in Patent Document 1. Below, use Figure 9 The configuration of a conventional vibration generating device will be described. Figure 9 The explanatory drawing showing the structure of a conventional vibration generator shows the structure of the conventional vibration generator 101 which concerns on patent document 1. As shown in FIG. It should be noted that, in Figure 9 In , the X direction, the Y direction, ...
