ところで、携帯電話機など通話可能な携帯端末の場合、通話中に一時的にマイク用の貫通孔を塞いで通話相手に聞こえないようにするハンドミュートを行うことがある。   By the way, in the case of a portable terminal such as a mobile phone, there is a case where hand mute is performed so as to temporarily close a through-hole for a microphone during a call so that the other party cannot hear it.

マイク用の貫通孔が筐体のカバーに設けられている場合、カバーの貫通孔の裏側周縁にクッション部材を貼り付けていると、カバーの脱着の際に剥がれてしまうので、クッション部材をカバーと筐体との間に密着させることができない。このため、ハンドミュートを行おうとしてもカバーと筐体との間で音が漏れてしまうという問題がある。   When the through hole for the microphone is provided in the cover of the housing, if the cushion member is attached to the back side periphery of the through hole of the cover, the cushion member is peeled off when the cover is detached. It cannot be in close contact with the housing. For this reason, there is a problem that sound leaks between the cover and the housing even if hand mute is performed.

本発明は、かかる点に鑑みてなされたものであり、その目的とするところは、筐体を覆うカバーにマイク用の貫通孔がある場合でも、ハンドミュートを確実に行えるようにすることにある。   The present invention has been made in view of such a point, and an object of the present invention is to ensure that hand mute can be performed even when a cover for covering the housing has a through hole for a microphone. .

上記の目的を達成するために、この発明では、カバーの脱着時にマイク用クッションが剥がれないようにした。   In order to achieve the above object, according to the present invention, the microphone cushion is not peeled off when the cover is attached or detached.

具体的には、本発明では、内部にマイクが内蔵され、該マイクへの音声が通過する第１マイク用貫通孔を有する筐体と、
上記筐体を覆い、上記第１マイク用貫通孔に対応する第２マイク用貫通孔を有するカバーと、
上記第１マイク用貫通孔の周縁である第１周縁及び上記第２マイク用貫通孔の周縁である第２周縁のいずれか一方に貼り付けられ、上記カバーで上記筐体を覆ったときに、上記第１周縁と上記第２周縁との間に圧縮状態で挟持される貫通孔を有するマイク用クッションとを備えた携帯端末を対象とする。 Specifically, in the present invention, a housing with a built-in microphone and having a first microphone through-hole through which sound to the microphone passes,
A cover that covers the housing and has a second microphone through hole corresponding to the first microphone through hole;
Affixed to either the first peripheral edge that is the peripheral edge of the first microphone through hole or the second peripheral edge that is the peripheral edge of the second microphone through hole, and when the casing is covered with the cover, A portable terminal including a microphone cushion having a through-hole sandwiched between the first peripheral edge and the second peripheral edge in a compressed state is an object.

そして、上記携帯端末は、
上記第１周縁及び上記第２周縁の上記マイク用クッションの外側には、上記カバーの脱着時に互いに当接することで、上記カバーを撓ませて上記第２周縁を上記第１周縁から遠ざける突部がそれぞれ形成されている。 And the mobile terminal
Protrusions on the outside of the microphone cushions on the first and second peripheral edges abut against each other when the cover is attached and detached, thereby bending the cover and moving the second peripheral edge away from the first peripheral edge. Each is formed.

上記の構成によると、カバーで筐体を覆ったときに、筐体側の第１周縁とカバー側の第２周縁との間にマイク用クッションを圧縮状態で挟持させるようにすることにより、ハンドミュート時にカバー裏面と筐体表面との間で音が漏れない。一方で、カバーの脱着時には、第１突部と第２突部とが当接することで、カバーが撓んで第２周縁が第１周縁から遠ざかるので、マイク用クッションが剥がれない。   According to the above configuration, when the casing is covered with the cover, the microphone cushion is sandwiched in a compressed state between the first peripheral edge on the casing side and the second peripheral edge on the cover side, thereby hand mute Sometimes sound does not leak between the back of the cover and the surface of the housing. On the other hand, when the cover is detached, the first protrusion and the second protrusion are brought into contact with each other, so that the cover is bent and the second peripheral edge moves away from the first peripheral edge, so that the microphone cushion is not peeled off.

以上説明したように、本発明によれば、マイク用クッションを筐体の貫通孔の第１周縁とカバーの貫通孔の第２周縁との間に圧縮状態で挟持し、カバーの脱着時に第１周縁の突部と第２周縁の突部とを当接させて第１周縁から第２周縁を遠ざけるようにしたことにより、筐体を覆うカバーにマイク用の貫通孔がある場合でも、ハンドミュートを確実に行えるようにする。   As described above, according to the present invention, the microphone cushion is sandwiched in a compressed state between the first peripheral edge of the through hole of the housing and the second peripheral edge of the through hole of the cover. Even if there is a microphone through hole in the cover that covers the housing, the peripheral protrusion and the second peripheral protrusion are brought into contact with each other so that the second peripheral edge is away from the first peripheral edge. To ensure that

以下、本発明の実施形態を図面に基づいて説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１〜図５は本発明の実施形態の携帯端末としての携帯電話機１を示し、この携帯電話機１は、例えば表面側にタッチパネルを含む表示部２を有するスマートフォンよりなる。表示部２は、正面側キャビネット３に収容され、その背面に背面側キャビネット４が結合されている。本実施形態では、正面側キャビネット３及び背面側キャビネット４が筐体を構成する。この筐体の背面をカバーとしてのリアカバー５が覆っている。正面側キャビネット３、背面側キャビネット４及びリアカバー５は、例えば樹脂成形品とするが、金属成形品でもよい。正面側キャビネット３と背面側キャビネット４とは、例えば、ビス８で締結されて枠状の防水パッキン６で防水されている。図７に示すように、リアカバー５の周縁には、複数の係合爪５ａが形成され、この係合爪５ａを正面側キャビネット３又は背面側キャビネット４に形成した係合穴４ａに係合するように、リアカバー５が筐体に嵌め込まれ、使用時に誤って外れてしまわないようになっている。   FIGS. 1-5 shows the mobile telephone 1 as a portable terminal of embodiment of this invention, and this mobile telephone 1 consists of a smart phone which has the display part 2 which contains a touch panel on the surface side, for example. The display unit 2 is accommodated in a front cabinet 3 and a back cabinet 4 is coupled to the back thereof. In this embodiment, the front side cabinet 3 and the back side cabinet 4 comprise a housing | casing. A rear cover 5 as a cover covers the back surface of the housing. The front side cabinet 3, the back side cabinet 4 and the rear cover 5 are, for example, resin molded products, but may be metal molded products. The front side cabinet 3 and the back side cabinet 4 are fastened with, for example, screws 8 and waterproofed with a frame-shaped waterproof packing 6. As shown in FIG. 7, a plurality of engagement claws 5 a are formed on the periphery of the rear cover 5, and the engagement claws 5 a are engaged with engagement holes 4 a formed in the front side cabinet 3 or the back side cabinet 4. As described above, the rear cover 5 is fitted into the housing so that it cannot be accidentally removed during use.

図１に拡大して示すように、携帯電話機１の内部には、マイク１０が内蔵され、このマイク１０が回路基板７に接続されている。正面側キャビネット３には、マイク１０への音声が通過する第１マイク用貫通孔１１が形成されている。なお、本実施形態では、正面側キャビネット３の下端は化粧カバー３ａで覆われているが、この化粧カバー３ａは、正面側キャビネット３と一体でもよい。背面側キャビネット４側にこの第１マイク用貫通孔１１が形成されていてもよい。マイク１０は、携帯電話機１の厚さをできるだけ薄くするために真下ではなく、斜めに向いている。マイク１０は、貫通孔を有してクッション性のある両面テープ１０ａで第１マイク用貫通孔１１の奥側周縁に貼り付けられている。第１マイク用貫通孔１１は、下方に向かって徐々に内径が大きくなっている。   As shown in an enlarged view in FIG. 1, a microphone 10 is built in the mobile phone 1, and the microphone 10 is connected to the circuit board 7. The front cabinet 3 is formed with a first microphone through-hole 11 through which sound to the microphone 10 passes. In the present embodiment, the lower end of the front cabinet 3 is covered with the decorative cover 3 a, but this decorative cover 3 a may be integrated with the front cabinet 3. The first microphone through hole 11 may be formed on the back side cabinet 4 side. The microphone 10 is directed not diagonally but diagonally to make the thickness of the mobile phone 1 as thin as possible. The microphone 10 has a through hole and is attached to the inner periphery of the first microphone through hole 11 with a cushioned double-sided tape 10a. The first microphone through-hole 11 has an inner diameter that gradually increases downward.

この第１マイク用貫通孔１１に対応するようにリアカバー５の下端側壁には、円形の第２マイク用貫通孔１２が形成されている。本実施形態では、第２マイク用貫通孔１２は、外観をよくするために第１マイク用貫通孔１１よりも内径が小さくなっているが、第１マイク用貫通孔１１と同程度の大きさでもよい。   A circular second microphone through hole 12 is formed in the lower end side wall of the rear cover 5 so as to correspond to the first microphone through hole 11. In the present embodiment, the second microphone through-hole 12 has an inner diameter smaller than that of the first microphone through-hole 11 in order to improve the appearance, but is approximately the same size as the first microphone through-hole 11. But you can.

図１及び図６に示すように、第１マイク用貫通孔１１の周縁である第１周縁１１ａは、矩形状平坦面が形成され、この平坦面にマイク用クッション１３が貼り付けられている。例えば、このマイク用クッション１３は、中心に貫通孔１３ａを有する矩形板状で、正面側キャビネット３側の片面に接着層が形成されている。   As shown in FIGS. 1 and 6, a rectangular flat surface is formed on the first peripheral edge 11a, which is the peripheral edge of the first microphone through hole 11, and a microphone cushion 13 is attached to the flat surface. For example, the microphone cushion 13 has a rectangular plate shape having a through hole 13a at the center, and an adhesive layer is formed on one side of the front cabinet 3 side.

図６に示すように、背面側キャビネット４は、この第１周縁１１ａに対応して矩形状に切欠４ｂが形成されている。切欠４ｂの正面側端部は、他の部分よりも低くなり、そのことで第１周縁１１ａを挟み込む一対の段部が形成され、この一対の段部の背面側の高くなった部分で第１突部１１ｂが構成されている。なお、この第１突部１１ｂは、背面側キャビネット４ではなく、正面側キャビネット３側を隆起させて設けてもよい。   As shown in FIG. 6, the back side cabinet 4 has a rectangular cutout 4b corresponding to the first peripheral edge 11a. The front side end of the notch 4b is lower than the other part, thereby forming a pair of stepped parts sandwiching the first peripheral edge 11a, and the first part is the raised part on the back side of the paired stepped parts. The protrusion 11b is configured. In addition, you may provide this 1st protrusion 11b by raising the front side cabinet 3 side instead of the back side cabinet 4. FIG.

図７に一部拡大して示すように、リアカバー５側の第２マイク用貫通孔１２の裏面側周縁である第２周縁１２ａは、マイク用クッション１３が当接する部分が矩形状の平坦面で構成されている。この第２周縁１２ａを挟み込むように、一対の第２突部１２ｂが形成されている。なお、第１周縁１１ａ側ではなく、第２周縁１２ａ側にマイク用クッション１３が貼り付けられていてもよい。   As shown in a partially enlarged view in FIG. 7, the second peripheral edge 12a, which is the rear peripheral edge of the second microphone through hole 12 on the rear cover 5 side, is a flat surface with a rectangular contact with the microphone cushion 13. It is configured. A pair of second protrusions 12b is formed so as to sandwich the second peripheral edge 12a. Note that the microphone cushion 13 may be attached to the second peripheral edge 12a side instead of the first peripheral edge 11a side.

図１に示すように、リアカバー５で正面側キャビネット３及び背面側キャビネット４を覆ったときには、第１突部１１ｂは、第２突部１２ｂよりもリアカバー５の取り外し方向（白抜き矢印で示す）にあり、隙間Ｘが保たれている。マイク用クッション１３は、第１周縁１１ａと第２周縁１２ａとの間に圧縮状態で挟持される。このため、第２マイク用貫通孔１２を手で塞げば、背面側キャビネット４をリアカバー５で覆っていても、マイク１０に音声が届かなくなり、ハンドミュートの機能を果たすことができる。   As shown in FIG. 1, when the front cover 3 and the back cabinet 4 are covered with the rear cover 5, the first protrusion 11b is removed from the rear cover 5 more than the second protrusion 12b (indicated by a white arrow). And the gap X is maintained. The microphone cushion 13 is sandwiched in a compressed state between the first peripheral edge 11a and the second peripheral edge 12a. For this reason, if the 2nd microphone through-hole 12 is plugged with a hand, even if the back side cabinet 4 is covered with the rear cover 5, an audio | voice will not reach the microphone 10 and the function of a hand mute can be achieved.

一方で、リアカバー５を外すときには、リアカバー５が筐体にある程度堅固に嵌め込まれているので、リアカバー５に爪等を引っ掛けて剥がすようにして取り外す。この剥がす動作において、第２突部１２ｂが第１突部１１ｂに乗り上げるので、第２周縁１２ａが第１周縁１１ａから遠ざけられる。このため、マイク用クッション１３には、こすりあげて剥がすような力が加わらないようになっている。   On the other hand, when the rear cover 5 is removed, the rear cover 5 is firmly fitted to the housing to some extent, so that the rear cover 5 is removed by hooking a nail or the like. In the peeling operation, the second protrusion 12b rides on the first protrusion 11b, so that the second peripheral edge 12a is moved away from the first peripheral edge 11a. For this reason, the microphone cushion 13 is prevented from being rubbed and peeled off.

このように、本実施形態では、リアカバー５で筐体を覆っているときには、第１突部１１ｂと第２突部１２ｂとが当接せず、マイク用クッション１３が第１周縁１１ａと第２周縁１２ａとで密閉状に挟持されるので、音漏れの少ないハンドミュートを行える。一方で、リアカバー５の脱着時には、第１突部１１ｂと第２突部１２ｂとが確実に当接するので、マイク用クッション１３が剥がれない。   Thus, in this embodiment, when the housing is covered with the rear cover 5, the first protrusion 11b and the second protrusion 12b do not come into contact with each other, and the microphone cushion 13 has the first peripheral edge 11a and the second edge. Since it is clamped between the periphery 12a, hand mute with little sound leakage can be performed. On the other hand, when the rear cover 5 is attached and detached, the first protrusion 11b and the second protrusion 12b reliably come into contact with each other, so that the microphone cushion 13 is not peeled off.

したがって、本実施形態に係る携帯端末によると、正面側キャビネット３及び背面側キャビネット４を覆うリアカバー５にマイク１０の貫通孔がある場合でも、ハンドミュートを確実に行えるようにする。   Therefore, according to the mobile terminal according to the present embodiment, even when the rear cover 5 covering the front side cabinet 3 and the back side cabinet 4 has a through hole of the microphone 10, the hand mute can be reliably performed.
