Abstract:
(EN) A speaker 100 comprises a main cone 1 and a sub cone 8. Linear thin-walled parts 10, 11 for reducing the thickness of the sub cone 8 are provided in a region including an outer side 14 and/or an inner side 13 of the sub cone 8. The linear thin-walled parts 10, 11 have components in both a radial direction 15 and a circumferential direction 16 of the sub cone 8, and the linear thin-walled part 10 and the linear thin-walled part 11 intersect each other at an intersection point 17. This configuration reduces the rigidity of the entire sub cone 8, promotes divided vibration of the sub cone 8, and especially promotes vibrational displacement of an outer peripheral part 9 to which sound is mainly emitted in the sub cone 8.
(FR) Un haut-parleur (100) comprend un cône principal (1) et un sous-cône (8). Des parties à paroi mince linéaires (10, 11) destinées à réduire l'épaisseur du sous-cône (8) sont disposées dans une région comprenant un côté extérieur (14) et/ou un côté intérieur (13) du sous-cône (8). Les parties à paroi mince linéaires (10, 11) ont des composants à la fois dans une direction radiale (15) et dans une direction circonférentielle (16) du sous-cône (8), et la partie à paroi mince linéaire (10) et la partie à paroi mince linéaire (11) se croisent au niveau d'un point d'intersection (17). Cette configuration réduit la rigidité de l'ensemble du sous-cône (8), favorise la vibration divisée du sous-cône (8), et favorise notamment le déplacement vibratoire d'une partie périphérique externe (9) vers laquelle le son est principalement émis dans le sous-cône (8).
(JA) スピーカー100は、メインコーン1とサブコーン8とを有している。サブコーン8の外側14または内側13の少なくともいずれか一方を含む部位には、サブコーン8の板厚を低下させるための線状の薄肉部10、11が設けられている。線状の薄肉部10、11は、サブコーン8の径方向15および周方向16の両方向の成分を有しており、線状の薄肉部10と線状の薄肉部11とは交点17で交差している。この構成により、サブコーン8全体の剛性が低下し、サブコーン8の分割振動が促進される。特に、サブコーン8において主に音が放射される外周部9の振動変位が促進される。
