Abstract

[Problem] To reduce, in a cellular phone, the space taken up by a microphone in the directions orthogonal and parallel to the thickness direction of a case. [Solution] An inner surface of a front case (1), said inner surface being at the periphery of the innermost portion of a sound path (11), is formed as a tilted surface (1a), which is tilted approximately 45° with respect to the thickness direction of the front case (1), and a microphone unit (21) is fixed to the tilted surface (1a) with a water-resistant film unit (12) therebetween. As a result, compared with when a microphone (25), including a water-resistant film unit (22), is disposed such that a sound collecting surface of the microphone is orthogonal or parallel to the thickness direction of the front case (1), the space taken up by the microphone (25) including the water-resistant film unit (22) can be reduced in the directions orthogonal and parallel to the thickness direction of the front case (1).

Description

携帯型電子機器Portable electronic devices
　この発明は携帯電話等の携帯型電子機器に関する。 The present invention relates to a portable electronic device such as a cellular phone.
　従来の携帯電話には、マイクロホンに呼気が直接当たらないようにすることにより、マイクロホンに入る雑音を低減するようにしたものがある（例えば、特許文献１参照）。特許文献１に記載の携帯電話では、ケースの厚さ方向の一面に音孔が設けられている。ケースの音孔の部分の内側には、溝からなる音道を有する音道形成部材が設けられている。音道の一端部は音孔に連通されている。音道形成部材の他端部に設けられたマイクロホン取付部にはマイクロホンが取り付けられている。この携帯電話では、音孔から入った呼気が音道を介してマイクロホンに入ることにより、呼気がマイクロホンに直接当たらないようにすることができる。 Some conventional mobile phones reduce noise entering the microphone by preventing direct exposure of the microphone (for example, see Patent Document 1). In the mobile phone described in Patent Document 1, a sound hole is provided on one surface in the thickness direction of the case. A sound path forming member having a sound path made of a groove is provided inside the sound hole portion of the case. One end of the sound path communicates with the sound hole. A microphone is attached to a microphone attachment portion provided at the other end of the sound path forming member. In this mobile phone, the exhaled air entering from the sound hole enters the microphone through the sound path, so that the exhaled air does not directly hit the microphone.
特開平７－２０２９９７号公報JP-A-7-202997
　ところで、音道形成部材の他端部に設けられたマイクロホン取付部にマイクロホンを取り付けるのではなく、ケースの内面にマイクロホンを両面接着テープを介して固着することが考えられる。しかしながら、このようにした場合には、両面接着テープを含むマイクロホンのケースの厚さ方向と直交する方向に占めるスペースが比較的大きくなってしまうという問題がある。 By the way, it is conceivable that the microphone is fixed to the inner surface of the case via a double-sided adhesive tape, instead of attaching the microphone to the microphone mounting portion provided at the other end of the sound path forming member. However, in this case, there is a problem that the space occupied in the direction orthogonal to the thickness direction of the microphone case including the double-sided adhesive tape becomes relatively large.
　そこで、この発明は、マイクロホンのケースの厚さ方向と直交する方向に占めるスペースは勿論のこと平行する方向に占めるスペースをも小さくすることができる携帯型電子機器を提供することを目的とする。 Therefore, an object of the present invention is to provide a portable electronic device that can reduce not only the space in the direction perpendicular to the thickness direction of the microphone case but also the space in the parallel direction.
　この発明に係る携帯型電子機器は、音孔を有するケースと、前記ケース内に、集音面が前記ケースの厚さ方向に対して傾斜するように設けられたマイクロホンと、前記音孔と前記マイクロホンの集音面との間に設けられた音道とを備えていることを特徴とするものである。 A portable electronic device according to the present invention includes a case having a sound hole, a microphone provided in the case so that a sound collection surface is inclined with respect to a thickness direction of the case, the sound hole, And a sound path provided between the microphone and the sound collection surface.
　この発明によれば、マイクロホンのケースの厚さ方向と直交する方向に占めるスペースは勿論のこと平行する方向に占めるスペースをも小さくすることができる。 According to the present invention, the space occupied in the direction parallel to the direction perpendicular to the thickness direction of the microphone case can be reduced as well as the space occupied in the parallel direction.

A sound hole 8 is provided on the right side of the front side wall of the front case 1.
　次に、図４は図３の切り欠いた部分を右側から見た断面図を示す。フロントケース１の所定の箇所には空洞からなる音道１１が設けられている。音道１１は、音孔８に連通され、且つ、フロントケース１の厚さ方向（図４において上下方向）とほぼ直交する第１の音道１１ａと、第１の音孔１１ａの奥部に連通され、且つ、フロントケース１の厚さ方向とほぼ平行して下方に延びる第２の音道１１ｂとによってほぼＬ字形状に曲がるように形成されている。 Next, FIG. 4 shows a cross-sectional view of the notched portion of FIG. 3 as viewed from the right side. A sound path 11 made of a cavity is provided at a predetermined location of the front case 1. The sound path 11 communicates with the sound hole 8 and is formed in a first sound path 11a that is substantially orthogonal to the thickness direction of the front case 1 (vertical direction in FIG. 4), and at the back of the first sound hole 11a. The second sound path 11b that communicates and extends downward in parallel with the thickness direction of the front case 1 is formed to be bent in an approximately L shape.
　第２の音道１１ｂの奥部の周囲におけるフロントケース１の内面は、フロントケース１の厚さ方向に対してほぼ４５°で傾斜する傾斜面１ａとなっている。傾斜面１ａには防水膜ユニット１２が固着されている。防水膜ユニット１２は、シート状の防水膜１３の上面外周部および下面外周部に両面接着テープ１４、１５が貼り付けられた構造となっている。防水膜１３は、空気は通すが水は通さないポリエチレンテレフタレート等の樹脂によって形成されている。両面接着テープ１４、１５の中央部つまり第２の音道１１ｂの奥部に対応する部分には開口部１６、１７が設けられている。 The inner surface of the front case 1 around the back of the second sound path 11b is an inclined surface 1a that is inclined at approximately 45 ° with respect to the thickness direction of the front case 1. A waterproof membrane unit 12 is fixed to the inclined surface 1a. The waterproof membrane unit 12 has a structure in which double-sided adhesive tapes 14 and 15 are affixed to the outer periphery of the upper surface and the outer periphery of the lower surface of the sheet-like waterproof film 13. The waterproof film 13 is formed of a resin such as polyethylene terephthalate that allows air to pass but not water. Openings 16 and 17 are provided in the center portion of the double-sided adhesive tapes 14 and 15, that is, the portion corresponding to the back portion of the second sound path 11b.
　そして、上側の両面接着テープ１４の上面がフロントケース１の傾斜面１ａに固着されている。下側の両面接着テープ１５の下面にはマイクロホンユニット２１が固着されている。マイクロホンユニット２１は、補強板２２の下面にフレキシブル配線板２３の一端部上面が接着剤（図示せず）を介して固着され、フレキシブル配線板２３の一端部下面に両面接着テープ２４を介してマイクロホン２５の集音面側が固着されている。補強板２２、フレキシブル配線板２３および両面接着テープ２４の中央部つまり両面接着テープ１５の開口部１７に対応する部分には開口部（符号省略）が設けられている。 The upper surface of the upper double-sided adhesive tape 14 is fixed to the inclined surface 1a of the front case 1. A microphone unit 21 is fixed to the lower surface of the lower double-sided adhesive tape 15. In the microphone unit 21, the upper surface of one end portion of the flexible wiring board 23 is fixed to the lower surface of the reinforcing plate 22 via an adhesive (not shown), and the microphone is attached to the lower surface of one end portion of the flexible wiring board 23 via a double-sided adhesive tape 24. The sound collecting surface side of 25 is fixed. An opening (reference numeral omitted) is provided in the central portion of the reinforcing plate 22, the flexible wiring board 23 and the double-sided adhesive tape 24, that is, the portion corresponding to the opening 17 of the double-sided adhesive tape 15.
　フロントケース１の傾斜面１ａと対向する部分におけるリアケース２の内面は、フロントケース１の傾斜面１ａと平行する傾斜面２ａとなっている。傾斜面２ａには発泡ウレタンゴム等からなるシート状のクッション部材２６が固着されている。そして、フロントケース１とリアケース２とをネジ（図示せず）で一体化した状態では、マイクロホン２５の下面（非集音面）がクッション部材２６に圧接され、且つ、補強板２２が両面接着テープ１５に圧接され、これによりマイクロホン２５の固定の安定化が図られている。 The inner surface of the rear case 2 at a portion facing the inclined surface 1a of the front case 1 is an inclined surface 2a parallel to the inclined surface 1a of the front case 1. A sheet-like cushion member 26 made of foamed urethane rubber or the like is fixed to the inclined surface 2a. When the front case 1 and the rear case 2 are integrated with screws (not shown), the lower surface (non-sound collecting surface) of the microphone 25 is pressed against the cushion member 26, and the reinforcing plate 22 is bonded on both sides. It is pressed against the tape 15 to stabilize the fixing of the microphone 25.
　フロントケース１の下面外周部には防水用溝３１がリング状に設けられている（図３参照）。防水用溝３１の内部にはシリコーンゴム等からなるシール部材３２が圧入されている。リアケース２の上面外周部において防水用溝３１に対応する部分には突起３３がリング状に設けられている。そして、フロントケース１とリアケース２とをネジ（図示せず）で一体化した状態では、突起３３がシール部材３２に圧接されることにより、フロントケース１とリアケース２との間がシールされている。 A waterproof groove 31 is provided in a ring shape on the outer periphery of the lower surface of the front case 1 (see FIG. 3). A sealing member 32 made of silicone rubber or the like is press-fitted inside the waterproof groove 31. A protrusion 33 is provided in a ring shape at a portion corresponding to the waterproof groove 31 in the outer peripheral portion of the upper surface of the rear case 2. In a state in which the front case 1 and the rear case 2 are integrated with screws (not shown), the protrusion 33 is pressed against the seal member 32 to seal between the front case 1 and the rear case 2. ing.
　なお、図４において、符号３４で示すものは、タッチパネル５の下面外周部をフロントケース１の上面に固着するための両面接着テープである。符号３５で示すものは、リアケース２と電池蓋３との間をシールするためのシール部材である。 In FIG. 4, what is indicated by reference numeral 34 is a double-sided adhesive tape for fixing the outer peripheral portion of the lower surface of the touch panel 5 to the upper surface of the front case 1. What is indicated by reference numeral 35 is a sealing member for sealing between the rear case 2 and the battery lid 3.
　以上のように、この携帯電話では、第２の音道１１ｂの奥部の周囲におけるフロントケース１の内面を、フロントケース１の厚さ方向に対してほぼ４５°で傾斜する傾斜面１ａとし、この傾斜面１ａに防水膜ユニット２２を介してマイクロホンユニット２１を固着しているので、両ケース１、２内にマイクロホン２５がその集音面がフロントケース１の厚さ方向に対してほぼ４５°傾斜するように配置されることになる。 As described above, in this mobile phone, the inner surface of the front case 1 around the back of the second sound path 11b is an inclined surface 1a that is inclined at approximately 45 ° with respect to the thickness direction of the front case 1, Since the microphone unit 21 is fixed to the inclined surface 1 a via the waterproof membrane unit 22, the microphone 25 in both cases 1 and 2 has a sound collection surface of approximately 45 ° with respect to the thickness direction of the front case 1. It will be arranged to incline.
　この結果、マイクロホン２５をその集音面がフロントケース１の厚さ方向に対して直交するように配置する場合および平行するように配置する場合と比較して、マイクロホン２５のフロントケース１の厚さ方向と直交する方向に占めるスペースおよび平行する方向に占めるスペースを小さくすることができる。 As a result, the thickness of the front case 1 of the microphone 25 is compared with the case where the microphone 25 is disposed so that the sound collection surface thereof is orthogonal to the thickness direction of the front case 1 and parallel. The space occupied in the direction orthogonal to the direction and the space occupied in the parallel direction can be reduced.
　ここで、防水膜ユニット１２の両面接着テープ１４の貼付幅は防水信頼性を得るために１～１．５ｍｍ程度は必要である。したがって、防水膜ユニット１２を含むマイクロホン２５のサイズは比較的大きくなってしまう。そこで、両ケース１、２内に防水膜ユニット１２を含むマイクロホン２５をその集音面がフロントケース１の厚さ方向に対してほぼ４５°傾斜するように配置すると、防水膜ユニット２２を含むマイクロホン２５のフロントケース１の厚さ方向と直交する方向に占めるスペースおよび平行する方向に占めるスペースを小さくすることができる。 Here, the width of the double-sided adhesive tape 14 on the waterproof membrane unit 12 needs to be about 1 to 1.5 mm in order to obtain waterproof reliability. Therefore, the size of the microphone 25 including the waterproof membrane unit 12 is relatively large. Therefore, when the microphone 25 including the waterproof membrane unit 12 is disposed in both the cases 1 and 2 so that the sound collection surface is inclined by approximately 45 ° with respect to the thickness direction of the front case 1, the microphone including the waterproof membrane unit 22 is disposed. The space occupied in the direction orthogonal to the thickness direction of the 25 front cases 1 and the space occupied in the parallel direction can be reduced.
　また、この携帯電話では、音道１１を、音孔８に連通され、且つ、フロントケース１の厚さ方向とほぼ直交する第１の音道１１ａと、第１の音道１１ａの奥部に連通され、且つ、フロントケース１の厚さ方向とほぼ平行して下方に延びる第２の音道１１ｂとによってほぼＬ字形状に曲がるように形成しているので、例えば図５に示すように、音孔８から細い棒状の異物４１が挿入されても、防水膜２３およびマイクロホン２５の集音面が破損しないようにすることができる。 Further, in this mobile phone, the sound path 11 is communicated with the sound hole 8, and the first sound path 11 a that is substantially orthogonal to the thickness direction of the front case 1 and the back of the first sound path 11 a. The second sound path 11b that is communicated and extends downward substantially parallel to the thickness direction of the front case 1 is formed so as to be bent substantially in an L shape. For example, as shown in FIG. Even if a thin rod-like foreign material 41 is inserted from the sound hole 8, the sound collecting surface of the waterproof film 23 and the microphone 25 can be prevented from being damaged.
　また、この携帯電話では、図１に示すように、フロントケース１の手前側の側壁の右側に音孔８を設けているので、通常の通話状態において音孔８が頬や指で塞がれることはなく、したがってユーザが意図せずに通話困難となる可能性を回避することができる。 Further, in this mobile phone, as shown in FIG. 1, since the sound hole 8 is provided on the right side of the front side wall of the front case 1, the sound hole 8 is blocked by a cheek or a finger in a normal call state. Therefore, it is possible to avoid the possibility that the telephone call becomes difficult unintentionally by the user.
　次に、マイクロホンユニット２１を組み込む場合について、図６に示す一部の斜視図を参照して説明する。まず、フロントケース１を裏返しにして、傾斜面１ａを上側とする。この場合、傾斜面１ａの左右両側におけるフロントケース１の内面には位置決め用凹部４２が設けられている。次に、マイクロホンユニット２１の下面に防水膜ユニット１２の両面接着テープ１５を貼り付けたものを準備する。この場合、補強板２２の左右両端部には位置決め用突起４３が設けられている。 Next, the case of incorporating the microphone unit 21 will be described with reference to a partial perspective view shown in FIG. First, the front case 1 is turned over, and the inclined surface 1a is set to the upper side. In this case, positioning concave portions 42 are provided on the inner surface of the front case 1 on both the left and right sides of the inclined surface 1a. Next, the microphone unit 21 is prepared by attaching the double-sided adhesive tape 15 of the waterproof membrane unit 12 to the lower surface of the microphone unit 21. In this case, positioning protrusions 43 are provided on both left and right ends of the reinforcing plate 22.
　次に、フロントケース１の位置決め用凹部４２にマイクロホンユニット２１の位置決め用突起４３を嵌め込みながら、フロントケース１の傾斜面１ａに防水膜ユニット１２の両面接着テープ１４を貼り付けると、図７に示すように、マイクロホンユニット２１が組み込まれる。この場合、傾斜面１ａに対してその上側から両面接着テープ１４を貼り付けることができるので、作業性が良い上、両面接着テープ１４を所期の荷重で所期の時間押え付けることができ、両面接着テープ１４の固着を良好とすることができる。なお、フロントケース１の傾斜面１ａに防水膜ユニット１２のみを貼り付け、その後に、防水膜ユニット１２にマイクロホンユニット２１を固着するようにしてもよい。 Next, when the double-sided adhesive tape 14 of the waterproof membrane unit 12 is attached to the inclined surface 1a of the front case 1 while the positioning protrusion 43 of the microphone unit 21 is fitted in the positioning recess 42 of the front case 1, as shown in FIG. Thus, the microphone unit 21 is incorporated. In this case, since the double-sided adhesive tape 14 can be affixed to the inclined surface 1a from above, the workability is good and the double-sided adhesive tape 14 can be pressed with the intended load for the intended time, Adhesion of the double-sided adhesive tape 14 can be made favorable. Note that only the waterproof membrane unit 12 may be attached to the inclined surface 1 a of the front case 1, and then the microphone unit 21 may be fixed to the waterproof membrane unit 12.
　ところで、この携帯電話では、より一層の薄型化を図ることができるようになっている。すなわち、図８に示すように、音道１１を音孔８と防水ユニット１２の両面接着テープ１４の開口部１６とを斜めの直線で結ぶ空洞とした場合には、音道１１の近傍におけるフロントケース１の防水用溝３１の部分の厚さが極端に薄くなってしまう。音道１１の近傍におけるフロントケース１の防水用溝３１の部分はシール部材３２の圧縮に伴う圧力を受けるため、ある程度の剛性すなわち厚さが必要である。 By the way, this cellular phone can be made thinner. That is, as shown in FIG. 8, when the sound path 11 is a cavity that connects the sound hole 8 and the opening 16 of the double-sided adhesive tape 14 of the waterproof unit 12 with an oblique straight line, the front in the vicinity of the sound path 11 is used. The thickness of the waterproof groove 31 of the case 1 becomes extremely thin. A portion of the waterproof groove 31 of the front case 1 in the vicinity of the sound path 11 receives pressure accompanying compression of the seal member 32, and therefore needs a certain degree of rigidity, that is, thickness.
　そこで、フロントケース１の防水用溝３１の部分の厚さをある程度厚くすると、必然的にリアケース２を図８において下側にある程度ずらして配置することになり、その分厚型化してしまう。これに対し、図４では、音道１１をほぼＬ字形状に曲がった空洞とし、このほぼＬ字形状に曲がった音道１１の内側にシール部材３２の一部を配置しているので、音道１１の近傍におけるフロントケース１の防水用溝３１の部分の厚さを十分確保することができ、ひいてはより一層の薄型化を図ることができる。 Therefore, if the thickness of the waterproof groove 31 of the front case 1 is increased to some extent, the rear case 2 is inevitably shifted to the lower side in FIG. 8 and the thickness is increased accordingly. On the other hand, in FIG. 4, the sound path 11 is formed as a cavity bent in a substantially L shape, and a part of the seal member 32 is disposed inside the sound path 11 bent in a substantially L shape. A sufficient thickness of the waterproof groove 31 of the front case 1 in the vicinity of the road 11 can be secured, and as a result, the thickness can be further reduced.
（第２実施形態）
　図９はこの発明の第２実施形態としての携帯電話の図４同様の断面図を示す。この携帯電話において、図４に示す携帯電話と異なる点は、音道１１を、ほぼＬ字形状に曲げるのではなく、ほぼ円弧形状に曲げた点である。この場合も、図５に示す場合と同様に、音孔８から細い棒状の異物４１が挿入されても、防水膜２３およびマイクロホン２５の集音面が破損しないようにすることができる。また、ほぼ円弧形状に曲がった音道１１の内側にシール部材３２の一部を配置することにより、音道１１の近傍におけるフロントケース１の防水用溝３１の部分の厚さを十分確保することができる。 (Second Embodiment)
FIG. 9 is a sectional view similar to FIG. 4 of a mobile phone as a second embodiment of the present invention. This cellular phone is different from the cellular phone shown in FIG. 4 in that the sound path 11 is not bent in a substantially L shape but is bent in a substantially arc shape. In this case as well, as in the case shown in FIG. 5, even if a thin stick-shaped foreign object 41 is inserted from the sound hole 8, the sound collecting surfaces of the waterproof film 23 and the microphone 25 can be prevented from being damaged. In addition, by arranging a part of the seal member 32 inside the sound path 11 bent in a substantially arc shape, a sufficient thickness of the waterproof groove 31 of the front case 1 in the vicinity of the sound path 11 is ensured. Can do.
（第３実施形態）
　図１０はこの発明の第３実施形態としての携帯電話の図４同様の断面図を示す。この携帯電話において、図４に示す携帯電話と大きく異なる点は、音孔８および音道１１を、フロントケース１ではなく、リアケース２に設けた点である。したがって、音道１１の奥部の周囲におけるリアケース２に設けられた傾斜面２ｂには防水ユニット１２を介してマイクロホンユニット２１が固着されている。リアケース２の傾斜面２ｂと対向する部分におけるフロントケース１に設けられた傾斜面１ｂにはクッション部材５１が設けられている。 (Third embodiment)
FIG. 10 is a sectional view similar to FIG. 4 of a mobile phone as a third embodiment of the present invention. This cellular phone is greatly different from the cellular phone shown in FIG. 4 in that the sound hole 8 and the sound path 11 are provided not in the front case 1 but in the rear case 2. Therefore, the microphone unit 21 is fixed to the inclined surface 2 b provided in the rear case 2 around the back of the sound path 11 via the waterproof unit 12. A cushion member 51 is provided on the inclined surface 1 b provided on the front case 1 in a portion facing the inclined surface 2 b of the rear case 2.
　また、この場合、リアケース２の上面外周部には防水用溝５２がリング状に設けられている。防水用溝５２の内部にはシール部材５３が圧入されている。フロントケース１の下面外周部において防水用溝５２に対応する部分には突起５４がリング状に設けられている。そして、フロントケース１とリアケース２とをネジ（図示せず）で一体化した状態では、突起５４がシール部材５３に圧接されることにより、フロントケース１とリアケース２との間がシールされている。 In this case, a waterproof groove 52 is provided in a ring shape on the outer periphery of the upper surface of the rear case 2. A seal member 53 is press-fitted inside the waterproof groove 52. A protrusion 54 is provided in a ring shape at a portion corresponding to the waterproof groove 52 in the outer peripheral portion of the lower surface of the front case 1. In a state where the front case 1 and the rear case 2 are integrated with screws (not shown), the projection 54 is pressed against the seal member 53 to seal between the front case 1 and the rear case 2. ing.
