Fig. 2 Fig. 3-61-˜ Heli real opening 50-1 '03629 (3) Fig. 6 2050? 00200501002000 ■ pLL (Hz) φ 1 63- DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to the improvement of a speaker cabinet, and its object is to improve the sound quality by suppressing the vibration of the cabinet. 11 shows a speaker cabinet, 12 is an exploded view thereof, 1 is a radish, 2, 2 'is a side plate, 3 is a back plate, 4 is a ground plate, and 5 is a front plate. In the conventional speaker cabinet, since the respective plates are directly fixed to each other, the vibrations #jJ of the respective plates are transmitted to each other, and the vibration in the bass is particularly severe, and the imaging dynamics thereof is There is a defect that it is superimposed on bamboo, causing so-called intermodulation, and the clear (1) +3 decreases. Figure 15 (K shows the measurement results of acceleration amplitude of each part of front plate 5 and rear plate 3; Fig. 51 (B) shows acceleration amplitude of each part of top plate 1, base plate 4 and side & 2 '2' It shows the result of measurement. As clarified by this measurement result, the front plate 5 and the rear plate 3 have a higher vibration than the other top plate 1, the ground & 4 and the side plates 2, 2 '. This device focuses on this point and separates the front plate 5 and the rear plate 3 where the vibration is severe from the other person 1, 2 '1 and the temporary plate 2, 2' and the ground plate 4, thereby the vibration of the speaker cabinet as a whole. The figure in Figure 13 shows an example of this. That is, the top plate 1, the side plates 2 and 2 ', and the main plate 4 are directly secured to each other in the conventional manner. 7 is a corner plate bonded to each of the front plate 5 and the rear plate 3 to the other top plate 1, side 01-05-2019 1 plates 2 and 2 'and the base plate 4 in a dam-this corner plate 7 is the front plate 5 in the prior art In the present invention, an elastic body 6 such as rubber is interposed between the corner plate 7 and the front plate 5 or (2)-) rear plate 3 in this invention. Glue with. If it comprises as mentioned above, the dynamic energy of the imaging of the front board soot and the back board 3 will be absorbed by the elastic body 6, and each other top board 1 .. * 1 The shooting motion transmitted to IFi 2, 2 and the main plate 4 is reduced. 3-4 (one 1 is an example of an elastic body 6 shown as a gold, and 8 is a groove cut into the elastic body 6 and provided at random intervals in a weir, a structure 1, a monumental body Assuming that the compliance is C and the trade percentage is M, the characteristic frequency is represented by fl'1f = 2 □ 5 □, but when the elastic body 6 is divided by the groove 8 as described above, the elastic body 6 is the front plate 5 Alternatively, since the rear plate 3 comes into contact with a random area, the wave number during pregnancy is averaged, and the frequency range for sound absorption can be broadened. Fig. 16 shows the embodiment of this invention and the conventional 7 "(') & t 7) l! lQi ′ ′-tD * ljh @ NttD measurement 112 ′ ′ where the solid line indicates the acceleration amplitude of the lateral roots at each frequency of the conventional one and the one with the dashed line. As shown in the figure (3), the vibration of the 1dol plate is reduced when the invention is implemented. As mentioned above, because the front plate and the rear plate are illustrated through the elastic body against the radish, both sides, and the ground plate as described above, the front plate and the back of the shooting movement are intense in the eyebrow The energy of the imaging motion transmitted from the board to each other board is absorbed by the elastic body, and the imaging motion as a whole of the speaker cabinet is reduced. As a result, the intermodulation due to the imaging of the speaker cabinet is reduced or low. The clarity in the sound range is improved. 01-05-2019 2
