Title (EN) SPEAKER AND ELECTRONIC APPARATUS AND DEVICE USING THE SAME
(FR) HAUT-PARLEUR, ET APPAREIL ET DISPOSITIF ÉLECTRONIQUES L’UTILISANT
(JA) スピーカおよびこれを用いた電子機器、装置
Abstract: front page image
(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.
(JA) 本発明は音響分野および情報通信分野のスピーカに関するものであり、薄型化を実現できるスピーカを提供するものである。そのために本発明のスピーカは、磁気回路の下部プレートのセンターポールに形成された窪みまたは孔に、振動板の一部を挿入してスピーカを構成する。これによって、磁気回路の高さ内に振動板の一部を収納することができ、スピーカの薄型化を図ることができる。
