DESCRIPTION JPS53161624
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of an acoustic box for a
speaker. FIG. 2 is a cross-sectional view of the acoustic box. ■ is a plastic sheet, ■ is a liquid.
Correction 52.8. 23
【Detailed description of the invention】 42 This utility model makes the plate of the acoustic
box a double sheet of plastic sheet 0) as shown in Fig. 2 and creates a space inside the plate V,
and liquid ■ in the space It is something to insert. The structure of the plate may be an inner
plate (one that forms a weir space). Further, the plate may be a metal plate, wood plate or the like
having water resistance and air tightness. By putting the liquid in the plate in this way, the
weight of the plate of the acoustic box is increased, the vibration generated in the speaker is
generated, and the vibration generated on the surface of the plate is absorbed by the liquid in the
plate The applicant for the utility model registration is Kimura Yumi-I. If liquid ■ is used as
water, and the water inlet and outlet are attached to the plate, and water is inserted when used,
the material of the plate can be saved when making an acoustic box, and one weight is light. It is
easy to carry. And since water can be obtained anywhere, it is convenient for general household
