电声换能器
摘要：
提出了一种电声换能器，包括:振荡装置(10)，从第一振动面输出声波(30)，并且从与所述第一振动面相对的第二振动面输出具有与声波(30)的相位相反的相位的声波(32);波导(40)，设置在所述第一振动面上并且包括开口端(46);波导(5)，设置在所述第二振动面上，并且包括与所述开口端(46)面朝相同方向的开口端(56);以及声波滤波器(80)，设置在所述波导(50)中，并且对所述声波(32)进行衰减。
摘要（英）：

Provided is an electroacoustic transducer equipped with: an oscillating device (10) which outputs acoustic waves (30) from a first vibratile surface, and which outputs acoustic waves (32) of an opposite phase of the acoustic waves (30) from a second vibratile surface on the reverse surface from the first vibratile surface; a waveguide (40) which is provided upon the first vibratile surface and which has an open end (46); a waveguide (50) which is provided upon the second vibratile surface and which has an open end (56) facing the same direction as the open end (46); and an acoustic wave filter (80) provided upon the waveguide (50) for attenuating the acoustic waves (32).
