摘要： A plurality of dummy bores with bottoms (21) are disposed in the vicinity of through holes (11) defining speaker sound emanating apertures. Each dummy bore (21) has a bottom shaped like a cone or pyramid (23) such that outer light rays (31) becoming incident through the dummy bores (21) are irregularly reflected from the bottom to emerge therefrom as decreased in intensity. With the above arrangement, the through holes (11) and dummy bores (21) may appear less differently from each other. Thus provided is a speaker grille of excellent design.
摘要翻译：具有底部（21）的多个虚拟孔设置在限定扬声器发声孔的通孔（11）附近。每个假孔（21）具有如锥形或金字塔（23）的底部，使得通过虚拟孔（21）入射的外部光线（31）从底部不规则地反射，从而从强度降低。通过上述布置，通孔（11）和虚拟孔（21）可以看起来彼此不同。因此提供了优秀设计的扬声器格栅。

摘要： A casing for an audiovisual equipment presents outer appearance giving the impression of integrating a hole area formed of a plurality of sound transmitting fine holes with the casing, thereby making the hole area unnoticeable. This allows a viewer to easily concentrate on the screen by eliminating anything noticeable and distracting from the area surrounding the screen, and also gives the outside of the casing a luxurious appearance. In order to make the hole area unnoticeable, maintain good volume and quality of sound from the speaker, and arrange the diameter .o slashed.d mm of the tapered fine holes to be practically the smallest, the relationship between the diameter .o slashed.d mm and the thickness T mm of the casing must be expressed by the following formula: (1/6).times.T mm.ltoreq..o slashed.d mm .apprxeq.0.5 mm. When the fine holes are formed to be straight, the relationship between the diameter .o slashed.ds mm and the thickness t mm of the casing must be expressed by the following formula: (1/5).times.t mm.ltoreq..o slashed.ds mm.ltoreq.0.5 mm.
