In the present embodiment, the shapes of the side end cover 1 and the speaker protection plate 15 are different from those of the first embodiment. 19 to 21 are a left side view of the side cover 1 and a partial rear perspective view of the speaker protection plate 15.

  In FIG. 19, the speaker protection plate 15 has a thin U-shaped cross-sectional shape in which the upper end and the lower end protrude forward with the same protrusion amount and the center is flat. The front end of the insertion portion 2, the first side wall portion 31, the connection portion 32, and the second side wall portion 33, along the vertical cross section of the speaker protection plate 15, protrude forward with the same protrusion amount, and the center is flat. It has a shape. Accordingly, the groove 34 in the side end cover 1 has a shape along the longitudinal section of the speaker protection plate 15, and the side end of the speaker protection plate 15 is inserted into the groove 34. The internal ribs 311, 311... Are provided on the front, upper and lower sides of the first side wall portion 31, respectively, and many internal ribs 311 are arranged in the front portion where the contact with the speaker protection plate 15 is large.

  By making the side end cover 1 and the speaker protection plate 15 into the shape shown in FIG. 19, the whole can be made thin and flat. The shape of the side end cover 1 and the speaker protection plate 15 shown in FIG. 19 is, for example, a case where large speakers 53, 53 are used in a large display device 90, and the speakers 53, 53 are not conspicuous, It is suitable when you want to give a sense of unity.

  In FIG. 20, the vertical cross section of the speaker protection plate 15 has a center projecting forward, and the center from the upper end and the center from the lower end form a straight line. The front end of the insertion portion 2, the first side wall portion 31, the connection portion 32, and the second side wall portion 33 are convex toward the front along the longitudinal section of the speaker protection plate 15. Therefore, the groove portion 34 in the side end cover 1 has a shape along the longitudinal section of the speaker protection plate 15, and the side end portion of the speaker protection plate 15 is inserted into the groove portion 34. A plurality of internal ribs 311, 311... Are provided at a distance from the portion excluding the apex of the first side wall portion 31. The reason why the inner ribs 311 and 311 are not provided at the apex of the side end cover 1 shown in FIG. 20 is that it fits with the side end cover 1 due to variations in the bending portion of the speaker protection plate 15 corresponding to the apex. This is because the state is likely to change and the positional relationship with the internal rib 311 is likely to change.

  In FIG. 21, the longitudinal section of the speaker protection plate 15 is such that the lower end protrudes forward from the upper end and the apex is provided at the lower end, and the upper end to the lower end are linear. The front end of the insertion portion 2, the first side wall portion 31, the connection portion 32, and the second side wall portion 33 have a shape along the longitudinal section of the speaker protection plate 15, and the lower end protrudes forward from the upper end and the apex is provided at the lower end. The upper end to the lower end are linear. Accordingly, the groove 34 in the side end cover 1 has a shape along the longitudinal section of the speaker protection plate 15, and the side end of the speaker protection plate 15 is inserted into the groove 34. A plurality of internal ribs 311, 311... Are provided at a distance from the portion excluding the apex of the first side wall portion 31.

  The side end cover 1 and the speaker protection plate 15 shown in FIG. 21 are, for example, a small display device 90, and are used when the vicinity of the speakers 53 and 53 is part of the pedestal.

  The embodiments disclosed herein are illustrative in all respects and should not be considered as restrictive. The scope of the present invention is defined not by the above-mentioned meaning but by the scope of the claims, and is intended to include all modifications within the meaning and scope equivalent to the scope of the claims.
