Description

本考案は、携帯端末の音響を改善する、携帯端末用カバーに関するものである。 The present invention relates to a cover for a mobile terminal that improves the sound of the mobile terminal.

スピーカー開口部５が、背面または側面にある携帯端末４で使われている従来の携帯端末用カバー１の図９または図１０では、スピーカー開口部５を塞がないように出口開口３が開いているだけなので、スピーカーから発生した音が拡散してしまい、正面に向かう量が少なくなり、音質や音量の低下を招き、聞き取りにくい。 In FIG. 9 or FIG. 10 of the conventional portable terminal cover 1 used in the portable terminal 4 having the speaker opening 5 on the back surface or the side surface, the outlet opening 3 is opened so as not to block the speaker opening 5. As a result, the sound generated from the speaker is diffused, and the amount going to the front is reduced, resulting in a decrease in sound quality and volume, making it difficult to hear.

特許文献１に開示されているような、携帯パソコンのバスレフポートの音を取り入れて、音質を改善する携帯パソコン用拡張音響箱が提案されている。 There has been proposed an extended acoustic box for a portable personal computer that improves the sound quality by incorporating the sound of the bass reflex port of the portable personal computer as disclosed in Patent Document 1.

特開２０００−５０３７７号公報JP 2000-50377 A

特許文献１の提案で改善される音域は低音域であり、中高音域の音は、正面を向いているスピーカーの音を直接聞いている。 The sound range improved by the proposal of Patent Document 1 is a low sound range, and the sound in the middle and high sound range is heard directly from the sound of the speaker facing the front.

本考案は、スピーカー開口部が、背面または側面にある携帯端末から発生する音の拡散を防ぎ、音質や音量の低下を改善する、携帯端末用カバーを提供することを目的とする。 An object of the present invention is to provide a cover for a portable terminal in which a speaker opening prevents diffusion of sound generated from a portable terminal on the back surface or a side surface, and improves a decrease in sound quality and volume.

上記課題を達成するために請求項１の考案では、携帯端末の背面にあるスピーカー開口部を携帯端末用カバーの取込口で覆い、携帯端末との間に作った空洞により、スピーカーの音を出口開口方向に誘導し、出口開口を携帯端末用カバーの正面に設けたことを特徴とする。 In order to achieve the above object, according to the first aspect of the present invention, the speaker opening on the back surface of the portable terminal is covered with the inlet of the portable terminal cover, and the sound of the speaker is produced by the cavity created between the portable terminal and the portable terminal. It is guided in the direction of the outlet opening, and the outlet opening is provided in front of the cover for the portable terminal.

請求項２の考案では、携帯端末の側面にあるスピーカー開口部を携帯端末用カバーの取込口で覆い、携帯端末との間に作った空洞により、スピーカーの音を出口開口方向に誘導し、出口開口を携帯端末用カバーの正面に設けたことを特徴とする。 In the invention of claim 2, the speaker opening on the side surface of the mobile terminal is covered with the intake of the cover for the mobile terminal, and the sound of the speaker is guided in the direction of the exit opening by the cavity created between the mobile terminal and An outlet opening is provided in front of the cover for the portable terminal.

請求項３の考案では、携帯端末の背面にあるスピーカー開口部を携帯端末用カバーの取込口で覆い、取込口から出口開口までの間を、周りの部分より薄くすることで携帯端末との間に空洞を作り、スピーカーの音を出口開口方向に誘導し、出口開口を携帯端末用カバーの正面に設けたことを特徴とする。 In the invention of claim 3, the speaker opening on the back of the portable terminal is covered with the inlet of the portable terminal cover, and the distance from the inlet to the outlet opening is made thinner than the surrounding portion to A cavity is formed between the two, and the sound of the speaker is guided toward the exit opening, and the exit opening is provided in front of the cover for the portable terminal.

請求項４の考案では、携帯端末の側面にあるスピーカー開口部を携帯端末用カバーの取込口で覆い、取込口から出口開口までの間を、周りの部分より薄くすることで携帯端末との間に空洞を作り、スピーカーの音を出口開口方向に誘導し、出口開口を携帯端末用カバーの正面に設けたことを特徴とする。 In the invention of claim 4, the speaker opening on the side surface of the portable terminal is covered with the intake of the cover for the portable terminal, and the distance from the intake to the outlet opening is made thinner than the surrounding portion to A cavity is formed between the two, and the sound of the speaker is guided toward the exit opening, and the exit opening is provided in front of the cover for the portable terminal.

請求項１または請求項２の考案によれば、スピーカーの音は、携帯端末用カバーと携帯端末との間にできた空洞を通って、拡散せず携帯端末用カバーの正面から出るため、音量の低下を防ぐことができ、指向性の強い高音域の音も出て音質も改善できる。 According to the first or second aspect of the present invention, the sound of the speaker passes through a cavity formed between the portable terminal cover and the portable terminal and does not diffuse but comes out from the front of the portable terminal cover. Can be prevented, and high-frequency sound with strong directivity is also emitted, improving the sound quality.

請求項３または請求項４の考案によれば、スピーカーの音は、携帯端末用カバーと携帯端末との間にできた空洞を通って、拡散せず携帯端末用カバーの正面から出るため、音量の低下を防ぐことができ、指向性の強い高音域の音も出て音質も改善できる。さらに取込口から出口開口までの空洞部分は、携帯端末用カバーの厚さを周りの部分より薄くすることで作っているため、請求項１または請求項２よりもコストが削減できる。 According to the invention of claim 3 or claim 4, since the sound of the speaker passes through the cavity formed between the mobile terminal cover and the mobile terminal, and does not diffuse, it comes out from the front of the mobile terminal cover. Can be prevented, and high-frequency sound with strong directivity is also emitted, improving the sound quality. Furthermore, since the hollow portion from the intake port to the outlet opening is made by making the thickness of the cover for the portable terminal thinner than the surrounding portion, the cost can be reduced more than in the first or second aspect.
