Abstract
(EN)
Provided is a speaker for an acoustic field and an information communication field which can be realized as a thin shape. For this, the speaker is configured by inserting a part of a diaphragm into a concave or a hole formed at a center pole of a lower plate of a magnetic circuit. This enables containing a part of the diaphragm within the height of the magnetic circuit, thereby realizing a thin shape.
(FR)
L'invention concerne un haut-parleur, destiné à un champ acoustique et à un champ de communication d'informations, qui peut être réalisé sous forme mince. Pour ceci, le haut-parleur est configuré en insérant une pièce d'un diaphragme dans un évidement ou dans un trou formé au niveau d'un pôle central d'une plaque inférieure d'un circuit magnétique. Ceci permet de contenir une pièce du diaphragme à l'intérieur de la hauteur du circuit magnétique, pour ainsi obtenir une forme mince.
