Title
(EN) SPEAKER DEVICE
(FR) DISPOSITIF HAUT-PARLEUR
(JA) スピーカ装置
Abstract
(EN)
A speaker device is provided with a vibration plate, a stationary section for supporting the vibration plate so that the vibration plate can vibrate in a vibration direction, and a drive section provided to the stationary section and applying vibration to the vibration plate by means of an audio signal.  The drive section is provided with a magnetic circuit for forming a magnetic gap, a voice coil vibrated in a direction different from the direction of vibration of the vibration plate by an audio signal inputted in the voice coil, and a vibrating direction changing section for transmitting vibration of the voice coil to the vibration plate after changing the direction of the vibration.  The vibration direction changing section is provided with joint sections connected to a mounting receiving member which includes both the vibration plate and the voice coil and located close to the mounting receiving member.  Contact avoiding sections which avoid contact with the joint sections are formed in that surface of the mounting receiving member which is located close to the joint sections.

La présente invention se rapporte à un dispositif haut-parleur comprenant une plaque vibrante, une section fixe qui sert à supporter la plaque vibrante de telle sorte que la plaque vibrante peut vibrer dans une direction de vibration, et une section d'entraînement qui comporte la section fixe et qui sert à appliquer des vibrations sur la plaque vibrante au moyen d'un signal audio. La section d'entraînement comprend un circuit magnétique pour former un entrefer magnétique, une bobine acoustique qui est amenée à vibrer dans une direction différente de la direction de vibration de la plaque vibrante par un signal audio entré dans la bobine acoustique, et une section de changement de direction de vibration qui sert à transmettre les vibrations de la bobine acoustique à la plaque vibrante après que la direction de la vibration a changé. La section de changement de direction de vibration comprend des sections de jonction qui sont connectées à un organe de réception et de montage comprenant à la fois la plaque vibrante et la bobine acoustique et qui sont placées à proximité de l'organe de réception et de montage. Des sections d'empêchement de mise en contact qui empêchent la mise en contact avec les sections de jonction sont formées sur la surface de l'organe de réception et de montage qui est placée à proximité des sections de jonction.
