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、正面方向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 range, and the sound in the middle and high range is directly heard from the speaker facing the front direction.

本考案は、内蔵スピーカーの開口部が、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安価に改善する、携帯端末用音響装置を提供することを目的とする。 An object of the present invention is to provide an audio device for a mobile terminal in which the opening of the built-in speaker prevents the diffusion of sound generated from the mobile terminal on the back or side surface and improves the reduction in sound quality and volume at low cost. To do.

上記課題を達成するために請求項１の考案では、携帯端末の背面用スピーカー開口部または、側面用スピーカー開口部を覆うように装着し、携帯端末との間にできた空洞により、内蔵スピーカーが発した音を出口方向に誘導し、音の出口を正面に向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 built-in speaker is mounted by a cavity formed so as to cover the speaker opening for the back surface or the speaker opening for the side surface of the portable terminal and between the portable terminal. The sound emitted is guided in the direction of the exit, and the sound exit is directed to the front.

請求項２の考案では、背面用スピーカー開口部がある携帯端末に装着し、内部の空洞が、仕切板で仕切られていることを特徴とする。 The invention of claim 2 is characterized in that it is mounted on a portable terminal having a rear speaker opening, and the internal cavity is partitioned by a partition plate.

請求項３の考案では、側面用スピーカー開口部がある携帯端末に装着し、内部の空洞が、仕切板で仕切られていることを特徴とする。 The invention of claim 3 is characterized in that it is mounted on a portable terminal having a side speaker opening, and an internal cavity is partitioned by a partition plate.

請求項１の考案によれば、内蔵スピーカーの音は、携帯端末用音響装置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の改善にもなる。 According to the first aspect of the present invention, the sound of the built-in speaker passes through the cavity formed between the portable terminal acoustic device and the portable terminal and is not diffused and is emitted from the front of the portable terminal. It can also produce high-frequency sounds with strong directivity, improving the sound quality.

請求項２の考案では、内部の空洞を仕切板で段違いに仕切ることにより、バックロードホーンを形成し、低音域の増強をしている。 According to the second aspect of the present invention, a back load horn is formed by partitioning an internal cavity in steps with a partition plate, thereby enhancing the low frequency range.

請求項３の考案では、内部の空洞を仕切板で長手方向に仕切ることにより、バスレフ型を形成し、低音域の増強をしている。 According to the third aspect of the present invention, a bass reflex type is formed by partitioning the internal cavity in the longitudinal direction with a partition plate, thereby enhancing the bass range.

（実施形態１）
図１は本考案の実施形態１にかかる携帯端末用音響装置の斜視図である。図１に示されるように、形状が内側に湾曲しているため携帯端末１に装着した場合には、携帯端末１と携帯端末用音響装置との間に空洞を形成し、内蔵スピーカーの音がその空洞を通って、携帯端末１の正面に向いた出口から出るようになっている。 (Embodiment 1)
FIG. 1 is a perspective view of an audio device for a portable terminal according to Embodiment 1 of the present invention. As shown in FIG. 1, since the shape is curved inward, when it is attached to the mobile terminal 1, a cavity is formed between the mobile terminal 1 and the mobile terminal acoustic device, and the sound of the built-in speaker is heard. It passes through the cavity and exits from the exit facing the front of the mobile terminal 1.

図２は本考案の実施形態１を携帯端末１に装着した側面図である。携帯端末１に内蔵された背面内蔵スピーカー２の背面用スピーカー開口部３または、側面内蔵スピーカー４の側面用スピーカー開口部５を覆うように装着し、背面内蔵スピーカー２または、側面内蔵スピーカー４の音が携帯端末１との間にできた空洞を通って、正面に出るようになっているため、音の拡散を防止し、音量や高音域の音質の低下を改善できる。 FIG. 2 is a side view of Embodiment 1 of the present invention mounted on the mobile terminal 1. It is mounted so as to cover the rear speaker opening 3 of the rear built-in speaker 2 built in the portable terminal 1 or the side speaker opening 5 of the side built-in speaker 4, and the sound of the rear built-in speaker 2 or the side built-in speaker 4. However, the sound can be prevented from diffusing and the deterioration of the sound volume and the sound quality in the high range can be improved.
