Title (EN) SOUND REPRODUCING DEVICE
(FR) DISPOSITIF DE REPRODUCTION SONORE
(JA) 音響再生装置
Abstract:
(EN) Provided is an earhole open-type sound reproducing device with which it is possible to obtain satisfactory sound quality across a wide bandwidth while employing bone conduction. A first equalizer 303 removes a high-frequency component which is difficult to reproduce using a vibrating speaker 301 and which is not readily transmitted by bone conduction. Sound ranging from a low-frequency region to a medium-frequency region is then output by means of bone-conducted sound from the vibrating speaker 301. The equalizing process performed by the first equalizer 303 also reduces leakage of sound in the high-frequency region. Meanwhile, a second equalizer 304 removes components ranging from the low-frequency region to the medium-frequency region. High quality high-frequency component sound is then output by means of air-conducted sound from an air-conduction speaker 302.
(FR) L'invention concerne un dispositif de reproduction sonore de type conduit auditif ouvert au moyen duquel il est possible d'obtenir une qualité sonore satisfaisante sur une grande largeur de bande tout en utilisant la conduction osseuse. Un premier égaliseur (303) élimine une composante haute fréquence qui est difficile à reproduire à l'aide d'un haut-parleur vibrant (301) et dont la transmission par conduction osseuse n'est pas facile. Le son allant d'une région basse fréquence à une région moyenne fréquence est ensuite émis par un son par conduction osseuse provenant du haut-parleur vibrant (301). Le processus d'égalisation effectué par le premier égaliseur (303) réduit également les fuites sonores dans la région haute fréquence. Pendant ce temps, un second égaliseur (304) élimine les composantes allant de la région basse fréquence à la région moyenne fréquence. Un son de composante haute fréquence de haute qualité est ensuite émis par un son par conduction aérienne depuis un haut-parleur à conduction aérienne (302).
(JA) 骨導式を採用しつつ、広帯域にわたって良好な音質を得ることができる、耳穴開放型の音響再生装置を提供する。 第1のイコライザー303は、振動スピーカー301では再生が困難で骨伝導では伝わり難い高域成分を除去する。そして、振動スピーカー301から、低域から中域にわたる音声を骨導音により出力する。第1のイコライザー303のイコライジング処理により、高域の音漏れを低減することにもなる。一方、第2のイコライザー304は、低域から中域にわたる成分を除去する。そして、気導スピーカー302から高品質の高域成分の音声を気導音により出力する。
