Abstract
(EN)
A vibration device (100) of the present invention is provided with a plate-like glass vibrator (G) and a plurality of exciters E which are mounted to the glass vibrator (G) and generate vibrations in accordance with an input electrical signal. An aspect ratio La/Lb of the length (La) of a long side and the length (Lb) of a short side of a rectangle (Sq) inscribed in the glass vibrator (G) is 1.2 to 50 inclusive, and a relational value α(α=Smin(n-1)/La) of the number n of the exciters (E) and the minimum value Smin of a distance between the exciters (E) is 0.2 to 0.8 inclusive. When n is 3 or more, the value β(β=Sσ/Save) obtained by dividing a standard deviation Sσ of the distance between the exciters (E) by an average value Save is 0 to 0.5 inclusive.

La présente invention concerne un dispositif de vibration (100) qui est pourvu d'un vibreur en verre de type plaque (G) et d'une pluralité d'excitateurs E qui sont montés sur le vibreur en verre (G) et génèrent des vibrations en fonction d'un signal électrique d'entrée. Un rapport d'aspect La/Lb de la longueur (La) d'un côté long et de la longueur (Lb) d'un côté court d'un rectangle (Sq) inscrit dans le vibreur en verre (G) est de 1,2 à 50 inclus, et une valeur relationnelle α(α=Smin(n-1)/La) du nombre n des excitateurs (E) et de la valeur minimale Smin d'une distance entre les excitateurs (E) est de 0,2 à 0,8 inclus. Lorsque n est égal ou supérieur à 3, la valeur β(β=Sσ/Save) obtenue en divisant un écart-type Sσ de la distance entre les excitateurs (E) par une valeur moyenne Save est de 0 à 0,5 inclus.
