【発明の属する技術分野】
１．発明の属する技術分野
本発明はフリップ型携帯電話に係り、特にフリップカバーに設けられたマイクロフォンを電話機本体内のオーディオ回路と電気的に接続する装置に関する。
【０００２】
【従来の技術】
２．関連技術の説明
一般的に、携帯用端末機はバータイプとフリップタイプに大別される。フリップ型携帯電話は、フリップ上のマイクロフォンが使用者の口に接近するため、バータイプの携帯電話より優れた音質を有する。フリップ型携帯電話の開発は、電話機の小型化趨勢と、これに伴いバータイプ携帯電話のマイクロフォンが使用者の口から遠くなることにより、要請が高まっている。また、フリップカバーは電話機のボタンを保護してボタンの誤動作を防止する役割を果たす。
【０００３】
通常のフリップ型携帯電話はフリップカバー、電話機本体及びフリップカバーと電話機本体を機械的に連結するヒンジ装置を含む。このフリップ型携帯電話はフリップカバーの閉時には通話待機モード、フリップカバーの開時には通話モードに設定されうる。この場合、マイクロフォンはフリップ型電話機本体の下端部又はフリップカバーに設けることができる。
【０００４】
携帯電話は使用者の口と耳との平均距離、すなわち、マイクロフォンと受話部との距離を確保しなければならないことからその小型化には限界がある。すなわち、マイクロフォンが設けられている送話部とスピーカーが設けられている受話部との距離は１４ｃｍ以上を維持すべきである。そこで、電話機本体長の減少を補うべく、フリップはフリップカバーにマイクロフォンを設けて通話距離を確保するのに用いられる。
【０００５】
ヒンジ装置を介してリングやマイクロフォンが設けられたフリップ要素を有する携帯電話技術が Beutlerなどにより米国特許第４，８９７，８７３号に開示されている。しかしながらBeutlerなどにより提案された携帯電話のフリップカバーは電話機本体と固着されてフリップカバーを電話機本体から分離することが不可能であることから、フリップカバーに過大な力が加えられると、フリップカバーは破損し、フリップに設けられたマイクロフォンが電話機からはずれることになるので、電話機としての使用が不可能となる。
【０００６】
発明の概要
電話機本体、フリップカバー及びフリップカバーを電話機本体と連結するためのヒンジ装置を備えるフリップ型携帯電話のマイクロフォン接続装置において、フリップカバーに設けられたマイクロフォンと、フリップカバーの一端の両側に備わり、外周面にガイド溝とガイド溝に備わる開口部とを備える一対のナックルと、平面部、曲面部、摺動面部及び係止面部から成り、フリップカバーの各ナックルに取り付けられており、摺動面部がナックルの開口部に挿入されてナックルの外周面から露出するとともに、マイクロフォンに電気的に接続されナックルに固定される第１接続端子と、平面部、接触面部及び係止面部を含み、接触面部は電話機本体の回転面から突出してナックルのガイド溝に当接するとともにナックルのガイド溝をヒンジ装置の回転軸方向と略垂直な方向に付勢し、電話機本体の両側に位置して電話機本体のオーディオ回路に接続される第２接続端子と、を備え、フリップカバーを電話機本体へ閉じたときにナックルの外周面から露出した第１接続端子の摺動面部が、電話機本体の回転面から突出した第２接続端子の各接触面部から離れ、フリップカバーを電話機本体から開くと、ナックルの外周面から露出した第１接続端子の摺動面部と、電話機本体の回転面から突出した第２接続端子の各接触面部が接触し、フリップカバーの開状態でマイクロフォンが第１接続端子を通じてオーディオ回路に電気的に接続される。

【００１３】
フリップカバー２００はレーザ融着によりケースに取り付けられた別途のラベルやシートカバーを有する。本発明では耳と口との平均距離（１４ｃｍ）を考慮して好ましくはマイクロフォン８０はフリップカバー２００の下部に設けられる。マイクロフォン８０を本体１００のオーディオ回路に電気的に接続する構造を説明すると、以下の通りである。
【００１４】
図２は第１接続端子９０をフリップカバー２００のナックル２１０に装着する状態を示す斜視図である。図３は第１接続端子９０がフリップカバー２００に装着された状態を示す平面図である。図４は図３の断面線Ｘ２−Ｘ２の断面図である。
【００１５】
図１〜図４に示したように、本発明の実施態様によるフリップカバー２００に取り付けられた接続装置は、フリップカバー２００に設けられる第１接続端子９０と本体１００に設けられる第２接続端子９５（図５）を有する。フリップカバー２００を開状態にすると、二つの接続端子９０，９５は互いに接触する。マイクロフォン８０はフリップカバー２００に設けられる。マイクロフォン８０のワイヤ８１は第１接続端子９０に電気的に接続される。一方、プリント回路基板(図示せず)に接続された第２接続端子９５は第１接続端子９０に対応する位置で本体１００に設けられる。ここで、第１及び第２接続端子９０，９５はフリップカバーの開状態で相互に接触する。
【００１６】
図２〜図４に示すように、フリップカバー２００は、それから延びるネック部２０１とそのネック部２０１から延びるナックル２１０を左右に備える。フリップカバー２００は本体１００からの着脱が可能であり、ナックル２１０の内部には係止部２２０が形成される。第１接続端子９０はナックル２１０と係止部２２０との間に図２記載の矢印方向へ装着される。ナックル２１０の外周面の所定位置にはガイド溝２１４が形成され、このガイド溝２１４には第１接続端子９０の一部が突出するための開口２１５が形成される。係止部２２０は着脱溝２２１を備え、ネック部２０１の周辺には第１接続端子９０の挿入のための溝２１２が形成される。
【００１７】
本発明の実施形態による第１接続端子９０は平面部９１、曲面部９２及び摺動面部９３を含む。平面部９１はワイヤ８１によりマイクロフォン８０に電気的に接続され、曲面部９２はナックル２１０と係止部２２０との間に挿入装着され、摺動面部９３はナックル２１０の外周面に形成された開口２１５に挿入されるとともに突出する。第１接続端子９０の端部９４は摺動面部９３が開口２１５に嵌合するように形成される。弾性的な曲面部９２を有する第１接続端子９０はナックル２１０の内周面に密着接触する。ナックル２１０の外周面に形成されたガイド溝２１４はフリップカバー２００を開く場合に第２接続端子９５の移動をガイドする。
【００１８】
図５は本発明の実施態様による第２接続端子９５が本体１００に設けられている状態を示した平面図であり、図６は図５の断面線Ｙ２−Ｙ２の断面図である。図５及び図６に示したように、第１及び第２ヒンジモジュールＭ１，Ｍ２は本体１００の下部に位置する収納部１０５の両側に設けられ、第２接続端子９５はバー形状の導電性弾性物質を曲げ処理することにより得られる。第２接続端子９５は平面部９６、接触面部９７及び係止面部９８を備える。この第２接続端子９５の平面部９６は本体１００のメインプリント回路基板１３０に固定され、それによってフリップカバー２００のマイクロフォン８０を本体１００のオーディオ回路に接続させる。頂点が本体１００の回転面１１０に突出する接触面部９７はフリップカバー２００の開状態で第１接続端子９０と接触する。係止面部９８は接触面部９７の移動を抑制して接触面部９７の過度の突出を防止する役割を果たす。第２接続端子９５も弾性を保持する。
【００１９】
図７は本発明の実施態様によるフリップカバー２００を本体１００に装着する状態を示す斜視図である。図８ａはフリップカバー２００の閉状態におけるマイクロフォン接続装置を示した断面図であり、図８ｂはフリップカバー２００の開状態におけるマイクロフォン接続装置を示した断面図である。
【００２０】
図７、図８ａ及び８ｂを参照すると、フリップカバー２００の係止部２２０にヒンジシャフト２の端部２２ａを強制的に挿入する。図８ａに図示したように、フリップカバー２００が約０゜の角度で待機状態にある場合、第１接続端子９０の摺動面部９３は第２接続端子９５の接触面部９７から離れる。一方、図８ｂに図示したように、フリップカバー２００が約１３５゜の角度で通話状態にある場合、摺動面部９３は回転面１１０に沿って面接触状態で移動するとともに、接触面部９７はガイド溝２１４に応じて面接触状態で移動する。次いで、第１接続端子９０は第２接続端子９５と接触してマイクロフォン８０を本体１００のプリント回路基板に接続させる。第１接続端子９０と第２接続端子９５との接触は弾性により維持される。
【００２１】
このようにフリップカバー２００の開状態でマイクロフォン８０はワイヤ８１を介して第１接続端子９０に接続される。第１接続端子９０の摺動面部９３は第２接続端子９５の接触面部９７と接触する。接触面部９７は平面部９６を介してプリント回路基板内のオーディオ回路に接続される。摺動面部９３と接触面部９７の両方が弾性を保持することで、接触状態を維持する。さらに、外部の衝撃が発生する場合でもその接触状態を維持することができる。
【００２２】
フリップカバー２００の閉状態では摺動面部９３が接触面部９７から離れてマイクロフォン８０と本体１００のオーディオ回路との接続状態を解除する。
【００２３】
仮に、フリップカバー２００に強い衝撃や過度の力が加えられるとしてもフリップカバー２００は容易にはずれ、使用者はフリップカバー２００を本体１００に容易に再装着することができる。
【００２４】
以上、本発明を特定の実施形態に基づいて説明したが、各種の変形が可能であることは請求の範囲により決められる本発明の範囲を逸脱しない限り、当該技術分野における通常の知識を持つ者により可能なのは明らかである。

BACKGROUND OF THE INVENTION
1. TECHNICAL FIELD The present invention relates to a flip-type mobile phone, and more particularly to an apparatus for electrically connecting a microphone provided on a flip cover to an audio circuit in a telephone body.
[0002]
[Prior art]
2. 2. Description of Related Art Generally, portable terminals are roughly classified into a bar type and a flip type. The flip type mobile phone has better sound quality than the bar type mobile phone because the microphone on the flip approaches the mouth of the user. The demand for development of flip-type mobile phones has increased due to the trend toward miniaturization of telephones and the accompanying increase in the microphones of bar-type mobile phones from the user's mouth. The flip cover also protects the buttons of the telephone and prevents the buttons from malfunctioning.
[0003]
A typical flip-type mobile phone includes a flip cover, a telephone body, and a hinge device that mechanically connects the flip cover and the telephone body. This flip-type mobile phone can be set in a call waiting mode when the flip cover is closed and in a call mode when the flip cover is opened. In this case, the microphone can be provided on the lower end portion of the flip-type telephone body or the flip cover.
[0004]
Since the mobile phone must secure the average distance between the user's mouth and ear, that is, the distance between the microphone and the receiver, there is a limit to downsizing the mobile phone. That is, the distance between the transmitter section provided with the microphone and the receiver section provided with the speaker should be maintained at 14 cm or more. Therefore, in order to make up for the decrease in the length of the telephone body, the flip is used to secure a conversation distance by providing a microphone on the flip cover.
[0005]
A mobile phone technology having a flip element provided with a ring or microphone via a hinge device is disclosed by Beutler et al. In US Pat. No. 4,897,873. However, since the flip cover of the mobile phone proposed by Beutler and the like is fixed to the phone body and it is impossible to separate the flip cover from the phone body, if an excessive force is applied to the flip cover, the flip cover Since it is damaged and the microphone provided on the flip is detached from the telephone, it cannot be used as a telephone.
[0006]
