The signal line 61 is inserted through the holes 52 c and 52 d of the second hinge part 52 and the hole 58 a of the packing 58. Further, since the passage 59 formed in the base 57 is formed by the groove 57f, when the cellular phone 1 is assembled, the signal line 61 is connected to the circuit board 31 and the second casing 3 as shown in FIG. The base 57 can be attached even after connecting to the electronic component. The signal line 61 is configured by, for example, a cable in which a metal wire is covered with an insulator.

図９は、第２ヒンジ部５２の内部構成等を示す分解斜視図である。第２ヒンジ部５２の内部には、音響／電気変換手段としてのスピーカ７１と、スピーカ７１を収容するインナーブラケット７２とが設けられる。なお、インナーブラケット７２は音道体として機能する。   FIG. 9 is an exploded perspective view showing an internal configuration and the like of the second hinge portion 52. Inside the second hinge portion 52, a speaker 71 as acoustic / electrical conversion means and an inner bracket 72 for housing the speaker 71 are provided. The inner bracket 72 functions as a sound road body.

スピーカ７１は、例えば、携帯電話機１に対して送信された電波を携帯電話機１が受信したときに受信をユーザに通知する着信音の鳴動用に利用される。スピーカ７１は、略円盤状に形成され、一方の面には放音部７１ａが、他方の面には電極部７１ｂが設けられる。電極部７１ｂは、信号線６１を介して回路基板３１と電気的に接続される。   The speaker 71 is used, for example, for ringing a ring tone that notifies the user of reception when the mobile phone 1 receives a radio wave transmitted to the mobile phone 1. The speaker 71 is formed in a substantially disk shape, and a sound emitting portion 71a is provided on one surface and an electrode portion 71b is provided on the other surface. The electrode part 71 b is electrically connected to the circuit board 31 through the signal line 61.

インナーブラケット７２は、本体部７５と、支持部７６とを備えている。本体部７５及び支持部７６は、例えば樹脂の一体成形によりそれぞれ形成される。本体部７５は、スピーカ７２を収容する略円盤状の収容部７５ａと、収容部７５ａから第２ヒンジ部５２内部側（図中上方側）へ突出する音道部７５ｂとを備えている。収容部７５ａの第２ヒンジ部５２の外部側にはスピーカ７１を収容可能な不図示の凹部が設けられている。音道部７５ｂは、収容部７５ａ側から第２ヒンジ部５２内部側へ向かって徐々に細くなるように形成されている。音道部７５ｂの内部には、収容部７５ａの凹部から音道部７５ｂの頂部７５ｃへ貫通する音道７５ｄが形成されている。なお、音道７５ｄも音道部７５ｂと同様に収容部７５ａ側から頂部７５ｃ側へ向かって徐々に細くなるように形成されている。   The inner bracket 72 includes a main body portion 75 and a support portion 76. The main body portion 75 and the support portion 76 are each formed by integral molding of resin, for example. The main body 75 includes a substantially disc-shaped housing portion 75a that houses the speaker 72, and a sound path portion 75b that protrudes from the housing portion 75a toward the inside of the second hinge portion 52 (upper side in the drawing). A recess (not shown) that can accommodate the speaker 71 is provided on the outside of the second hinge portion 52 of the housing portion 75a. The sound path portion 75b is formed so as to become gradually narrower from the housing portion 75a side toward the inside of the second hinge portion 52. Inside the sound path portion 75b, a sound path 75d penetrating from the concave portion of the housing portion 75a to the top portion 75c of the sound path portion 75b is formed. In addition, the sound path 75d is formed so as to be gradually narrowed from the housing part 75a side to the top part 75c side, similarly to the sound path part 75b.

支持部７６は、枠部７６ａと、枠部７６ａから収容部７５ａを囲むように延びる複数の足部７６ｂと、枠部７６ａの第１ヒンジパーツ５３側（図中奥手方向）に設けられる位置決め部７６ｃとを有している。本体部７５は、音道部７５ｂが枠部７６ａの孔部７６ｄに嵌入されるとともに、収容部７５ａが足部７６ｂへ嵌入されて支持部７６に固定される。支持部７６は、枠部７６ａ等に設けられた貫通孔７６ｅに挿通される不図示のネジが正面側ケース３ｃに螺合されることにより第２筐体３に固定される。   The support portion 76 includes a frame portion 76a, a plurality of feet 76b extending from the frame portion 76a so as to surround the accommodating portion 75a, and a positioning portion provided on the first hinge part 53 side (the back direction in the drawing) of the frame portion 76a. 76c. In the main body 75, the sound path portion 75b is fitted into the hole 76d of the frame portion 76a, and the accommodating portion 75a is fitted into the foot portion 76b and fixed to the support portion 76. The support portion 76 is fixed to the second housing 3 by screwing a screw (not shown) inserted through a through hole 76e provided in the frame portion 76a and the like into the front side case 3c.

第２ヒンジ部５２は、第２筐体３の正面側（図中上方側）であって、連結される側と反対側（図中左側）において、第２筐体３から正面側に向かって延びる突出面５２ｅと、突出面５２ｅから第２筐体３の連結される側へ折れ曲がる折れ面５２ｆとを有し、突出面５２ｅと折れ面５２ｆとの接続部にはパネル取り付け部５２ｇが設けられている。パネル取り付け部５２ｇの第２ヒンジパーツ５４側（図中手前側）には、スピーカ７１の放音のための音孔５２ｈが複数設けられている。音孔５２ｈは、突出面５２ｅから折れ面５２ｆに亘って延びるスリット状に形成され、第１ヒンジパーツ５３側から第２ヒンジパーツ５４側へ配列されている。インナーブラケット７２の頂部７５ｃは、パネル取り付け部５２ｇの筐体内部側に合致する。また、音道７５ｄの頂部７５ｃ側の開口部は、突出面５２ｅ及び折れ面５２ｆに向かって開口し、音孔５２ｈが設けられた範囲と略一致する大きさに形成されている。   The second hinge portion 52 is the front side (upper side in the figure) of the second casing 3 and is directed from the second casing 3 toward the front side on the opposite side (left side in the figure) to the connected side. It has a projecting surface 52e that extends and a bent surface 52f that bends from the projecting surface 52e to the side to which the second housing 3 is connected. A panel attachment portion 52g is provided at the connection between the projecting surface 52e and the folded surface 52f. ing. A plurality of sound holes 52h for sound emission of the speaker 71 are provided on the second hinge part 54 side (the front side in the figure) of the panel mounting portion 52g. The sound holes 52h are formed in a slit shape extending from the protruding surface 52e to the bent surface 52f, and are arranged from the first hinge part 53 side to the second hinge part 54 side. The top portion 75c of the inner bracket 72 matches the inside of the housing of the panel attachment portion 52g. The opening on the top 75c side of the sound path 75d opens toward the projecting surface 52e and the bent surface 52f, and is formed in a size that substantially matches the range in which the sound hole 52h is provided.

パネル取り付け部５２ｇには、導電部材としてのリンガーパネル７３が設けられる。リンガーパネル７３は、例えば金属により形成され、音孔５２ｈよりも小さい孔部が複数設けられた金網やパンチングメタルにより構成される。パネル取り付け部５２ｇは突出面５２ｅ、折れ面５２ｆの表面に凹状に形成されており、リンガーパネル７３はパネル取り付け部５２ｇに嵌合するとともに、例えば両面テープにより固定される。   The panel attachment portion 52g is provided with a ringer panel 73 as a conductive member. The ringer panel 73 is made of, for example, metal, and is made of a metal mesh or punching metal provided with a plurality of holes smaller than the sound holes 52h. The panel attaching portion 52g is formed in a concave shape on the surface of the protruding surface 52e and the bent surface 52f, and the ringer panel 73 is fitted to the panel attaching portion 52g and fixed by, for example, a double-sided tape.

インナーブラケット７２は、第２ヒンジ部５２の突出面５２ｅと、インナーブラケット７２の音道部７５ｂとが当接するように配置される。なお、突出面５２ｅ及び音道部７５ｂの突出面５２ｅと対向する面は、徐々に勾配が大きくなるように形成されており、互いに合致する。一方、音道部７５ｂの突出面５２ｅとは反対側には、音道部７５ｂと第２ヒンジ部５２内側面との間にスペースが確保される。第２ヒンジパーツ５４内部に形成された通路５９から延出した信号線６１は、当該スペースを通過して位置決め部７６ｃに設けられた位置決め通路７６ｆに挿通され、第２筐体３の内部へ延びる。従って、筐体の開閉により信号線６１がたわんだりしても、信号線６１は、音道部７５ｂの外側面により音道部７５ｂの側方に位置決めされるとともに、リンガーパネル７３に対し信号線６１が第２ヒンジパーツ５４よりも近くなることのないよう位置決めされる。また、位置決め部７６ｃは第２ヒンジ部５２の孔部５２ｃよりも筐体内部側（図中下方）に位置するから、第２ヒンジパーツ５４から延出した信号線６１は筐体内部側へ向かって延び、リンガーパネル７３は、信号線６１よりも第１及び第２ヒンジパーツ５３、５４の近くに配置されることになる。   The inner bracket 72 is disposed so that the protruding surface 52e of the second hinge portion 52 and the sound path portion 75b of the inner bracket 72 are in contact with each other. Note that the surface of the protruding surface 52e and the surface of the sound path portion 75b facing the protruding surface 52e are formed so that the gradient gradually increases and match each other. On the other hand, a space is secured between the sound path portion 75b and the inner surface of the second hinge portion 52 on the opposite side of the projecting surface 52e of the sound path portion 75b. The signal line 61 extending from the passage 59 formed inside the second hinge part 54 passes through the space and is inserted into the positioning passage 76f provided in the positioning portion 76c, and extends into the second housing 3. . Therefore, even if the signal line 61 bends due to the opening and closing of the housing, the signal line 61 is positioned on the side of the sound path part 75 b by the outer surface of the sound path part 75 b and the signal line with respect to the ringer panel 73. 61 is positioned so as not to be closer than the second hinge part 54. Further, since the positioning portion 76c is located on the inner side (lower side in the figure) of the hole portion 52c of the second hinge portion 52, the signal line 61 extending from the second hinge part 54 faces the inner side of the housing. The ringer panel 73 is arranged closer to the first and second hinge parts 53 and 54 than the signal line 61.

以上の実施形態によれば、第２ヒンジパーツ５４に形成された通路に信号線６１が配置され、第２ヒンジパーツ５４がシールドケース３２に電気的に導通されているから、静電気は第２ヒンジパーツ５４によりシールドケース３２に誘導され、さらには回路基板３１のグランドに誘導され、静電気が信号線６１に及ぼす影響が緩和される。また、回路基板３１は電池に接続されているから、静電気は大きな容量をもつ電池に吸収される。   According to the above embodiment, since the signal line 61 is disposed in the passage formed in the second hinge part 54 and the second hinge part 54 is electrically connected to the shield case 32, static electricity is generated in the second hinge. By being guided to the shield case 32 by the part 54 and further to the ground of the circuit board 31, the influence of static electricity on the signal line 61 is mitigated. Since the circuit board 31 is connected to the battery, static electricity is absorbed by the battery having a large capacity.

ヒンジパーツ５３、５４及びシールドケース３２は、ネジ５０１により第１筐体２に共締めされ、互いに圧着されるから、回路基板３１だけにヒンジパーツ５４を取り付ける場合に比較して、厚みのあるネジ止めができる。これによりねじれに強い固定ができ、携帯電話機１の開閉の際に負荷がかかるヒンジパーツを堅固に固定できる。なお、シールドケース３２だけでなく、回路基板３１も共締めするようにしてもよい。   Since the hinge parts 53 and 54 and the shield case 32 are fastened together with the first housing 2 by screws 501 and are crimped to each other, the screws are thicker than when the hinge parts 54 are attached only to the circuit board 31. Can be stopped. Thereby, it is possible to fix firmly against twisting, and it is possible to firmly fix the hinge part that is loaded when the mobile phone 1 is opened and closed. Note that not only the shield case 32 but also the circuit board 31 may be fastened together.

第２ヒンジ部５２には、音孔５２ｈが設けられるが、音孔５２ｈを覆うリンガーパネル７３が設けられているため、静電気はリンガーパネル７３により吸収され、信号線６１に直接放電されない。リンガーパネル７３に吸収された静電気はヒンジパーツ５３、５４へ飛び、シールドケース３２に誘導されるから、信号線への静電気の影響が緩和される。リンガーパネル７３とヒンジパーツ５３、５４との距離を、リンガーパネル７３と信号線６１との距離よりも短くなるように設定している上、シールドケース３２に導通されるため、より効果的にリンガーパネル７３からヒンジパーツ５３、５４へ静電気を誘導できる。本実施形態では、リンガーパネル７３とヒンジパーツ５３、５４とは接触していないが、接触させてもよい。   The second hinge portion 52 is provided with a sound hole 52h, but since a ringer panel 73 covering the sound hole 52h is provided, static electricity is absorbed by the ringer panel 73 and is not directly discharged to the signal line 61. The static electricity absorbed by the ringer panel 73 jumps to the hinge parts 53 and 54 and is guided to the shield case 32, so that the influence of static electricity on the signal line is mitigated. Since the distance between the ringer panel 73 and the hinge parts 53 and 54 is set to be shorter than the distance between the ringer panel 73 and the signal line 61, the ringer panel 73 is electrically connected to the shield case 32. Static electricity can be induced from the panel 73 to the hinge parts 53 and 54. In the present embodiment, the ringer panel 73 and the hinge parts 53 and 54 are not in contact, but may be in contact with each other.

インナーブラケット７２を設けることにより、音道７５ｄを確保することができるとともに、信号線６１を音孔５２ｈから遠ざけ、音孔５２ｈから進入した静電気が信号線６１へ落ちることを防止できる。   By providing the inner bracket 72, the sound path 75d can be secured, and the signal line 61 can be kept away from the sound hole 52h, and static electricity that has entered from the sound hole 52h can be prevented from falling to the signal line 61.
