(FR) DISPOSITIF HAUT-PARLEUR
(JA) スピーカ装置
Abstract:
(EN) A thin speaker device capable of emitting reproduced sound of a large volume. The speaker device has a drive section (14) for applying vibration to a vibrating plate (10) by a voice signal. The drive section (14) is provided with a magnetic circuit (20) for forming a magnetic gap (20G) in a direction different from the direction of vibration of the vibrating plate (10), a voice coil support section (40) having a voice coil (30) supported in the magnetic gap (20G) and capable of vibrating along the magnetic gap (20G), and a vibrating-direction converting section (50) having rigidity and transmitting vibration of the voice coil support section (40) to the vibrating plate (10) after changing the direction of the vibration. A connecting section (60) is provided between that end (50A) of the vibrating-direction converting section (50) which is on the voice coil support section (40) side and that end (40A) of the voice coil support section (40) which is on the vibrating-direction converting section side, and the positions of both the ends (50A, 40A) are made to be different in the direction of vibration.
(FR) Dispositif haut-parleur mince, susceptible de reproduire un son dans un grand volume. Le dispositif haut-parleur comprend une partie d'excitation (14) conçue pour faire vibrer une plaque vibrante (10) à partir d'un signal vocal. La partie d'excitation (14) comprend un circuit magnétique (20) conçu pour former un entrefer (20G) suivant une direction différente de la direction de vibration de la plaque vibrante (10) ; une partie de maintien (40) de bobine mobile comportant une bobine mobile (30) maintenue dans l'entrefer (20G) et susceptible de vibrer le long de l'entrefer (20G) ; et une partie de modification (50) de direction de vibration possédant une certaine raideur et transmettant les vibrations de la partie de maintien (40) de bobine mobile à la plaque vibrante (10) après modification de la direction de vibration. Une partie de raccord (60) est insérée entre l'extrémité (50A) de la partie de modification (50) de la direction de vibration (50) côté partie de maintien (40) de bobine mobile et l'extrémité (40A) de la partie de maintien (40) de bobine mobile côté partie de modification (50) de la direction de vibration. Les deux extrémités (50A, 40A) occupent des positions différentes dans la direction de vibration.
(JA)  大音量の再生音を放射することができる薄型のスピーカ装置を提供する。音声信号によって振動板10に振動を与える駆動部14を備え、駆動部14は、振動板10の振動方向とは異なる方向に沿って磁気ギャップ20Gを形成する磁気回路20と、磁気ギャップ20G内に支持されるボイスコイル30を有し磁気ギャップ20Gに沿って振動可能なボイスコイル支持部40と、ボイスコイル支持部40の振動を方向変換して振動板10に伝える剛性の振動方向変換部50とを備え、振動方向変換部50におけるボイスコイル支持部40側の端部50Aとボイスコイル支持部40の振動方向変換部側の端部40Aとの間に両端部の位置を振動方向に沿って異ならせて連結する連結部60を備える。
