Title
(EN) ELECTROACOUSTIC TRANSDUCER
(FR) TRANSDUCTEUR ÉLECTROACOUSTIQUE
(JA) 電気音響変換器
Abstract
(EN)
An electroacoustic transducer for outputting a sound wave that corresponds to a sound signal applied from the outside, wherein it is made possible to realize a consistent acoustic characteristic from a low sound range to a high sound range. Provided are earphones 1F comprising: a housing 10; a bulkhead 30’ for dividing the inside space of the housing 10 into a first space 100-1 and a second space 100-2 differing in volume from the first space 100-1; a vibrator 20 provided inside of the housing 10, one surface of which faces both the first space 100-1 and the second space 100-2; and a tube 50 for causing a sound wave radiation opening 60 to communicate with each of the first space 100-1 and the second space 100-2.

La présente invention concerne un transducteur électroacoustique pour délivrer en sortie une onde sonore qui correspond à un signal sonore appliqué depuis l'extérieur, dans lequel il est rendu possible de réaliser une caractéristique acoustique cohérente d'une plage sonore basse à une plage sonore élevée. L'invention concerne des écouteurs 1F comprenant : un boîtier 10 ; une cloison 30' pour diviser l'espace intérieur du boîtier 10 en un premier espace 100-1 et un second espace 100-2 différent du volume du premier espace 100-1 ; un vibreur 20 disposé à l'intérieur du boîtier 10, dont une surface fait face à la fois au premier espace 100-1 et au second espace 100-2 ; et un tube 50 pour amener une ouverture de rayonnement d'onde sonore 60 à communiquer avec chacun du premier espace 100-1 et du second espace 100-2.
