摘要 |
Sound generated by a sound emitting unit passes through a first sound passage defined between a first shielding board and a shielding cylinder and a second sound passage defined between a second shielding board and the shielding cylinder, and is emitted outside from a sound emitting hole defined in at least one of a case and a cover. The second shielding board and the shielding cylinder shield a space between the sound emitting hole and the first sound passage when the first sound passage is seen from the sound emitting hole. |
