Title
(EN) ACOUSTIC EXCITER AND SPEAKER USING IT
(FR) EXCITATEUR ACOUSTIQUE ET HAUT-PARLEUR L'UTILISANT
(JA) 音響加振器およびこれを用いたスピーカ
Abstract
(EN)
An acoustic exciter comprises a suspension made of an elastic material, which is coupled to the opening part of a frame, and a vibrator to which a voice coil disposed in the magnetic gap of a magnetic circuit connected to the suspension is coupled. An elastic body is so disposed between the frame and the vibrator as to be pressed against the frame and the vibrator. Thereby, the exciting efficiency of the vibrator can be increased, and the performance and tone quality of the acoustic exciter can be improved.
(FR)
La présente invention concerne un excitateur acoustique qui comprend une suspension en matériau élastique, couplée à une partie ouverture d'un cadre, et un vibrateur sur lequel est couplée une bobine acoustique disposée dans l'entrefer magnétique d'un circuit magnétique connecté à la suspension. Un corps élastique est disposé entre le cadre et le vibrateur de manière à être comprimé contre le cadre et le vibrateur. Ceci permet d'augmenter l'efficacité d'excitation du vibrateur et d'améliorer la performance et la qualité sonore de l'excitateur acoustique.
(JA)
 音響加振器は、フレームの開口に結合された弾性材からなるサスペンションと、このサスペンションに結合された磁気回路の磁気ギャップに配置されたボイスコイルを結合した振動子とから構成し、フレームと振動子間にこれらと圧接される弾性体を配置したものであり、弾性体を介在させることで、振動子の加振効率を向上させ、音響加振器の能率、音質の改善を図るものである。
