<p><P>PROBLEM TO BE SOLVED: To provide an amplifier base that can not only acoustically perform insulation between an amplifier and a floor by a damping mechanism, such as a spring member so as to prevent acoustic wave vibration from a speaker body of the amplifier from directly transferring to the floor, but also enhance the acoustic characteristics of the amplifier, by effectively and positively utilizing the acoustic wave vibration downward from the speaker body of the amplifier. <P>SOLUTION: The amplifier base comprises a top plate 2 having an amplifier mounting area 21 on the top face and a through hole 22 to the bottom face in the amplifier mounting area 21, a pair of side plates 3 arranged across the through hole 22 so as to leave a gap 31 at a rear end and expand to both sides toward the front on the bottom face of the top plate 2, a bottom plate 4, arranged under the top plate 2 via the both side plates 3 to form a resonant hollow 6 which cooperates with the top plate 2 and the both side plates 3 to penetrate in an anteroposterior direction and expands to the both sides toward the front, and a vibration-absorbing legs 5 arranged on the bottom face of the bottom plate 4 and stably mounting the bottom plate 4 with the members thereon integratedly over the floor 7. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
