Description

右と左のスピーカーの前面に置かれた反射するガイド板によって右と左の外側から出る間接音が部屋の左右の外壁や反射物に反射して直接音に対して拡散する音源として聞こえるので、音場感が増加する。図６に基づいて説明すると、前記反射物を反射板（１８）、（１９）とし、これを本発明による音響ガイド器（２０）、（２１）の外側に設けることでこの両部位の間（２２）、（２３）からホーン効果として指向性の広い中，低音帯域の音が導かれる。
これによって音源が左右のスピーカー（２４）、（２５）の外側（２６）、（２７）にあるように聞こえ、広い音場感が得られる。低音帯域の音は当該反射板（１８）、（１９）の外側から得られる。 Since heard as sound source indirect sound emanating from the outside of the right and left by the guide plate to reflect placed in front of the right and left speakers to diffuse against the direct sound and reflected to the left and right outer walls and the reflection of the room, Sound field feeling increases. Referring to FIG. 6, the reflectors are the reflectors (18) and (19), and these are provided outside the acoustic guides (20) and (21) according to the present invention. From 22) and (23), a medium and low frequency band sound having a wide directivity is derived as a horn effect.
As a result, the sound source sounds as if it were outside the left and right speakers (24), (25) (26), (27), and a wide sound field feeling is obtained. The sound in the low frequency band is obtained from outside the reflectors (18) and (19).
