Abstract
(EN)
The present invention provides an electroacoustic transducer and an acoustic device, the electroacoustic transducer making it possible to listen to ambient sound, too, while listening to sound obtained by vibration based on an electric signal, and suppress sound leakage due to vibration of a casing. This electroacoustic transducer is characterized by being provided with: an electromechanical transducer 2 which transduces an electric signal into mechanical vibration; and a casing 4 which is attachable to a cavum conchae without closing an external auditory canal, houses the electromechanical transducer 2 therein, and generates sound by vibrating by mechanical vibration caused by the electromechanical transducer 2, wherein the casing 4 is provided with an inner casing portion 40 located on the external auditory canal side and an outer casing portion 41 located on the outside when attached to the cavum conchae, and the casing 4 is ellipsoid-shaped or egg-shaped.

La présente invention concerne un transducteur électroacoustique et un dispositif acoustique, le transducteur électroacoustique permettant d'écouter le son ambiant, tout en écoutant le son obtenu par une vibration basée sur un signal électrique, et de supprimer une fuite sonore due à une vibration d'un boîtier. Ce transducteur électroacoustique est caractérisé en ce qu'il comporte : un transducteur électromécanique (2) qui transduit un signal électrique en vibration mécanique; et un boîtier (4) qui peut être fixé à une conque sans fermer un canal auditif externe, loge le transducteur électromécanique (2) à l'intérieur de celui-ci, et génère un son par vibration mécanique provoquée par le transducteur électromécanique (2), le boîtier (4) étant pourvu d'une partie de boîtier interne (40) située sur le côté de canal auditif externe et d'une partie de boîtier externe (41) située sur l'extérieur lorsqu'elle est fixée a la conque, et le boîtier (4) est en forme d'ellipsoïde ou d'œuf.
