DETAILED DESCRIPTION OF THE INVENTION The present invention is intended to provide an
excellent sound-entry device capable of obtaining a desired sound effect with a simple
configuration associated with an acoustic device such as a radio receiver or a tape recorder. . A
radio receiver and a tape recorder which are generally used are all cabinets only) K simply
forming a sound emitting hole tube and configuring only to emit the sound from the speaker
through the sound emitting hole) sound emitting hole Because the size of is constant, it is
variable to the size of preference, and the heat effect is large heat. B 2-72 is 0) 2 plan is to
eliminate the above-mentioned conventional fractures and 1) to provide an excellent soundinstrument tube which can obtain any sound change effect with a simple configuration. As an
example of the following two audio devices, the Chee Pley Cog with radio is taken as an example
9. One embodiment will be described with reference to the drawings. In the figure, one cabinet,
two sound emission holes formed on the front of the cabinet 1, one speaker mounted in the
cabinet 1 facing the three sound emission holes 2, and four speakers A grille slidably mounted on
the front of the cabinet 1, a sound emitting hole 6 formed on the grill 4, and a grille 4 tsupported groove formed on the front of the cabinet 1. In the above embodiment, as shown in
FIG. 1 and FIG. 2r, when the grille 4t--leftwards to the left, the sound release holes 6 of the grille
4 and the sound release holes 2 of the cabinet 1 are mutually released. The sound hole 2 is
completely closed by the grille 4. Therefore, in this situation, it is possible to prevent the
infiltration of the body during the pre-IIIK phase of spy 13. When the grille 4 is moved to the
right * by 8 lines as shown in FIGS. 8I1 and 4B, the sound emission hole 6 of the grill 4 matches

the sound emission hole 2 of the cabinet 1, and The sound release hole 2 is fully opened. ???
??? In this state, the sound from the loudspeaker 3 is the most radiated. According to the
above embodiment, by the sliding of the grille, the opening state of the sound emission hole is
changed, and according to this, it is possible to arbitrarily obtain nine sound effects! ?????
??? In the above embodiment, the description was made of sliding the grille in the horizontal
direction, but the grille may be configured to be rotatable, or the grille may be configured to slide
in the vertical direction. As is clear from the above 1st example, the grille is slidably mounted,
and the sliding of the grille makes the cabinecit's sound emitting hole tube 1lIIF! To obtain any
sound effect from the sound output hole 1Illf, for inconvenient-to block the KFi plaster hole to
prevent the intrusion of this 9 in 1 It is very useful 4 for the work collection.
