SPEAKER SYSTEM AND ROAD-SURFACE BURIED VOICE GENERATING DEVICE ADOPTING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a road-surface buried voice generating device which makes it possible to install road-surface buried blocks at all places needed to guide a walk of a visually handicapped person and is free of the possibility of water entry and dust cloud clogging. SOLUTION: A speaker 3 is incorporated in a hollow road-surface buried block 7 while the vibration surface 3a of the speaker 3 is directed to a plate type one-side part 7a positioned on the road surface side of the hollow road-surface buried block 7 and an edge part 3b of the vibration surface 3a is brought into close contact with the plate type one-side part side, and the speaker 3 is arranged at the plate type one-side part 7a across an abutting member 24 having a blow-out hole 25 bored large enough to face the vibration surface 3a and brought into contact with the abutting member making a round of the vibration surface edge part of the speaker so that the blow-out hole 25 of the abutting member 24 is closed; and the abutting member 24 has a plurality of passages 8b for passing a sound wave generated by the vibration of the vibration surface 3a to outside from the blow-out hole bored radially around the vibration surface 3a of the speaker 3 and the sound wave passes through the passages 8b, so that the plate type one-side plate 7a vibrates.
