PROBLEM TO BE SOLVED: To mechanically magnify the music box sounds generated from a music box. SOLUTION: This magnifier 1 is constituted by mounting a base plate 4 integral with the music box 5 at a frame 2. The vibration by the music box sounds generated from the music box 5 is transmitted to this base plate 4 on which the music box 5 is placed. The vibration by the music box sounds transmitted to the base plate 4 is picked up by a vibration transmission rod 6 and is magnified by a diaphragm 7. The vibration by the music box sounds magnified by the diaphragm 7 is made further louder within the audible band by a horn 8. |
