Abstract
(EN) A power generation device, provided with: a holding part 101 in which the natural frequency is fA; and two or more vibration power generation elements 105 that are held by the holding part 101, the vibration power generation elements 105 having different natural frequencies. From among the vibration power generation elements 105, the vibration power generation element having the lowest natural frequency has a natural frequency fBmin satisfying Expression 1, and the vibration power generation element having the highest natural frequency has a natural frequency fBmax satisfying Expression 2. N is the number of the vibration power generation elements 105. Expression 1: fBmin ≥ (0.925 - 2.5N/100)fA Expression 2: fBmax ≤ (1.075 + 2.5N/100)fA
(FR) L'invention concerne un dispositif de production d'énergie qui comprend : une partie de maintien 101 dans laquelle la fréquence naturelle est fA ; et au moins deux éléments de production d'énergie vibratoire 105 qui sont maintenus par la partie de maintien 101, les éléments de production d'énergie vibratoire 105 ayant des fréquences naturelles différentes. Parmi les éléments de production d'énergie vibratoire 105, l'élément de production d'énergie vibratoire ayant la fréquence naturelle la plus basse a une fréquence naturelle fBmin satisfaisant à l'expression 1, et l'élément de production d'énergie vibratoire ayant la fréquence naturelle la plus élevée a une fréquence naturelle fBmax satisfaisant à l'expression 2. N est le nombre d'éléments de production d'énergie vibratoire 105. Expression 1 : fBmin ≥ (0,925 - 2,5N/100)fA Expression 2 : fBmax ≤ (1,075 + 2,5N/100)fA
(JA) 発電装置は、固有振動数がfAである保持部101と、保持部101に保持され、固有振動数が互いに異なる2以上の振動発電素子105とを備えている。振動発電素子105のうち、固有振動数が最も低い振動発電素子の固有振動数fBminは以下の式1を満たし、固有振動数が最も高い振動発電素子の固有振動数fBmaxは以下の式2を満たす。但し、Nは振動発電素子105の個数である。 fBmin≧(0.925-2.5N/100)fA・・・(式1) fBmax≦(1.075+2.5N/100)fA・・・(式2)
