PROBLEM TO BE SOLVED: To provide electronic equipment such that the inside is made hard to see from a portion of case of the equipment where a sound pass, without impairing sound quality. SOLUTION: White upper meshes 254 on a side close to the eye 262 of a user and black lower meshes 252 on a distant side are disposed between a protector 243 of a speaker 224 and a case sound hole 224 of a mobile phone. The intensity of light 261H, reflected by the upper meshes 254, of light 261 incident on the case sound hole 224 from outside is much larger than that of reflected light of light entering the inside once, so the inside of the speaker 226 can not be practically confirmed with the eye 262.
