PROBLEM TO BE SOLVED: To clearly reproduce and collect sounds between two speakers or microphones and a performer located in an oblique direction in an acoustic device capable of performing stereophonic reproduction and stereophonic collection.SOLUTION: On a front face of a support 110, two vibrators 1 are provided while being spaced apart from each other. The vibrators 1 include wing-like vibration parts forming a valley 6 between side parts of one of convex surfaces of a pair of curvature plates 11 and are disposed in such a manner that the convex surfaces of the curvature plates 11 constitute a part of the front face of the support 110, and disposed while being tilted in a direction where a length direction of each of the valleys 6 is orthogonal with a spacing direction of both the vibrators in such a manner that a mutual interval between the valleys 6 of both the vibrators 1 is widened gradually from one end of the valley 6 to the other end.SELECTED DRAWING: Figure 1 【課題】ステレオ再生、ステレオ集音可能な音響装置において、二つのスピーカやマイクの間で斜め方向に配置される演奏者等との間でも明瞭な音の再生、集音を可能にする。【解決手段】支持体１１０の前面部に、二つの振動体１が相互間隔をおいて設けられているとともに、これら振動体１は、一対の湾曲板１１の各々の凸面の一方の側部どうしの間で谷部６を形成した翼状振動部を有し、湾曲板１１の凸面が支持体１１０の前面部の一部を構成するように配置され、かつ、両振動体１の谷部６の相互間隔を谷部６の一端から他端に向けて漸次広げるように各谷部６の長さ方向が両振動体の離間方向と直交する方向に対して傾斜して配置されている。【選択図】 図１
