| description | To realize consistent acoustic characteristics from a low frequency range to a high frequency range in an electro-acoustic transducer that outputs a sound wave according to a sound signal given from the outside.SOLUTION: An earphone 1F includes a housing 10, a partition 30' that divides an inner space of the housing 10 into a first space 100-1 and a second space 100-2 having a volume different from that of the first space 100-1, a vibrating body 20 provided in the housing 10 and having one surface facing both the first space 100-1 and the second space 100-2, and a pipe 50 that connects each of the first space 100-1 and the second space 100-2 with a sound wave emission port 60.SELECTED DRAWING: Figure 8
【課題】外部から与えられる音信号に応じた音波を出力する電気音響変換器において、低音域から高音域まで一貫した音響特性を実現することを可能にする。【解決手段】筐体１０と、筐体１０の内側空間を、第１の空間１００−１と第１の空間１００−１とは容積の異なる第２の空間１００−２に分割する隔壁３０´と、筐体１０内に設けられ、一方の面が第１の空間１００−１および第２の空間１００−２の両者に向かう振動体２０と、第１の空間１００−１および第２の空間１００−２の各々と音波放射口６０とを連通させる管５０とを備えたイヤホン１Ｆを提供する。【選択図】図８ |
