PROBLEM TO BE SOLVED: To provide a cover for a portable terminal capable of facilitating the amplification output of reproduction sound to be emitted from a speaker of the portable terminal while suppressing the increase of the number of components by using the portable terminal.SOLUTION: A cover 10 for a portable terminal includes a cover body 11 and a swelling part 40. The cover body has a first recession 31 and is attached to the portable terminal when the cover for the portable terminal is mounted on the portable terminal 1, to thereby constitute an acoustic route 50 in cooperation with the portable terminal that clogs a part of the first recession. The swelling part has an opening 41 and a second recession 42 and constitutes a sound emission port 51 that communicates with the acoustic route by using the opening and the second recession. The first recession of the cover body has a sound input part 33 and a communication part 34. The communication part includes a horn shape part 36 whose cross sectional area is enlarged from a sound input part side toward a second recession side, and allows the sound input part and the second recession to communicate each other via the horn shape part. 【課題】携帯端末を利用することで部品点数の増加を抑えながら、前記携帯端末のスピーカ部から発せられる再生音を容易に増幅して出力することができる携帯端末用カバーの提供する。【解決手段】携帯端末用カバー１０は、カバー本体１１と膨出部４０とを備える。前記カバー本体は、第１凹部３１を有し、前記携帯端末用カバーの携帯端末１への装着時に、前記携帯端末に取り付けられて、前記第１凹部の一部を閉塞した前記携帯端末と協働して音響経路５０を構成する。前記膨出部は、開口部４１および第２凹部４２を有し、これらを用いて前記音響経路に連通し得る放音口５１を構成する。前記カバー本体の第１凹部は、音入力部３３と連通部３４とを有している。前記連通部は、前記音入力部側から前記第２凹部側に向かうに従って断面積が拡大するホーン形状部３６を含み、前記音入力部と前記第２凹部とを前記ホーン形状部を介して連通させる。【選択図】図８
