Abstract

PURPOSE:To establish the electroacoustic mutual converter for external ear which can communicate with one ear only, by mounting the piezoelectric element so that the main oscillation direction is mutually orthogonal. CONSTITUTION:The case 1 has the projection 2 insertionable to the external ear, and in the projection 2, the first piezoelectric element 3 acting like an ear microphone and the second piezoelectric element 4 acting like an ear phone, are provided. Further, the main oscillation directions of the first piezoelectric element 3 and the second piezoelectric element are installed so that they are orthogonal each other, and the oscillation of one element by that of another can be avoided. Thus, communication is possible only with one ear.
