<p><P>PROBLEM TO BE SOLVED: To easily emit sound generated in a vibrator to the outside when used as an electrostatic type speaker and to easily convert sound generated outside to acoustic signals when used as an electrostatic type microphone, in an electrostatic type electroacoustic transducer. <P>SOLUTION: Elastic members 21U and 21L which are nonwoven fabric are positioned holding a vibrator 11 therebetween, and electrodes 31U and 31L having a plurality of through-holes passing through from a front surface to a back surface are positioned on the outer side of the elastic members 21U and 21L. Elastic members 22U and 22L which are nonwoven fabric are positioned on the outer side of the electrodes 31U and 31L, and vibrators 12U and 12L are positioned on the outer side of the elastic members 22U and 22L. Also, the conductive film of the vibrator 12U and the conductive film of the vibrator 12L are electrically connected, and connected to the ground GND. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
