Abstract

La présente invention vise à permettre une réduction de l'épaisseur d'un dispositif générateur à énergie vibratoire, même dans le cas d'une structure dans laquelle une unité côté mobile est logée à l'intérieur d'un boîtier. Le dispositif générateur à énergie vibratoire est structuré de telle sorte qu'une unité côté mobile comprenant une bobine conductrice vibre verticalement par rapport à une unité côté fixe (40) comprenant des aimants (42) et des culasses (44), et est pourvu d'un boîtier (50), servant d'unité côté fixe (40), destiné à loger l'unité côté mobile. En outre, le dispositif présente une structure dans laquelle des parties concaves (50Ac, 50Bc) sont respectivement formées sur une paire de parties de surface de paroi avant et arrière (50Aa, 50Ba) du boîtier (50), et une paire d'ouvertures supérieure et inférieure (50Ad, 50Bd), agencées verticalement, sont respectivement formées dans les parties concaves (50Ac, 50Bc). De plus, le dispositif est structuré de telle sorte que les culasses (44) sont soutenues sur les parties concaves (50Ac, 50Bc), et les aimants (42) sont logés dans les ouvertures respectives (50Ad, 50Bd) de manière à être magnétiquement attirés vers les culasses (44). Par conséquent, les aimants (42) et les culasses (44) peuvent être agencés à l'aide de portions des parties de surface de paroi respectives (50Aa, 50Ba).
