上述以外のピンは非接続である。
順接続時には、(レセプタクル側のピンA1-プラグ側のピンA1)(レセプタクル側のピンB1-プラグ側のピンB1)(レセプタクル側のピンA12-プラグ側のピンA12)(レセプタクル側のピンB12-プラグ側のピンB12)が接続される。
逆接続時には、(レセプタクル側のピンA1-プラグ側のピンB1)(レセプタクル側のピンB1-プラグ側のピンA1)(レセプタクル側のピンA12-プラグ側のピンB12)(レセプタクル側のピンB12-プラグ側のピンA12)が接続される。
図6は第1の実施の形態における変換ケーブルの構成を示す。図4と同様にヘッドセットが接続されるジャック11とプラグPL1がケーブルを介して接続されている。ヘッドセットは、ジャック11に挿入される丸型の4極プラグに対してイヤホンケーブルを介してイヤホンが接続された構成を有する。さらに、左右のチャンネルに対して共通のグラウンドラインのイヤホンケーブルが設けられる。ジャック11はプラグが挿入されるとONする検出スイッチ13を有する。
図7は、受信機側のレセプタクルRE1に関連する構成を示している。本技術の第1の実施の形態では、レセプタクル(又はプラグ)を正面から見た時に対角位置に存在するピンA1(GND)及びB1(GND)を通じてRF信号を伝送する。前述したように、RF信号としてのアンテナ信号がプラグPL1のピンB1に対して供給されている。プラグPL1がレセプタクルRE1に順接続される場合には、レセプタクルRE1のピンB1にアンテナ信号が供給され、プラグPL1がレセプタクルRE1に逆接続される場合には、レセプタクルRE1のピンA1にアンテナ信号が供給される。すなわち、表面及び裏面のどちらを上にしてもプラグPL1がレセプタクルRE1に挿入できるので、レセプタクルRE1のピンA1及びB1の一方からアンテナ信号が受信機に対して入力される。
図8は第1の実施の形態におけるケーブルの構成例(プラグPL2)を示す。上述した変換ケーブルは、ジャック11とプラグPL1がケーブルを介して接続されている構成であるのに対して、プラグPL2はジャック11(検出スイッチ13)を有しない構成である。オーディオアダプタアクセサリーモードが認識されるために、プラグPL2のピンA5(CC)及びB5(VCONN)が互いにピンA12(GND)及びB12(GND)に接続される。
「第2の実施の形態における変換ケーブルの構成例」
図9は第2の実施の形態における変換ケーブルの構成を示す。図6に示す第1の実施の形態の変換ケーブルと同様にヘッドセットが接続されるジャック11とプラグPL3がケーブルを介して接続されている。ヘッドセットは、ジャック11に挿入される丸型の4極プラグに対してイヤホンケーブルを介してイヤホンが接続された構成を有する。さらに、左右のチャンネルに対して共通のグラウンドラインのイヤホンケーブルが設けられる。ジャック11はプラグが挿入されるとONする検出スイッチ13を有する。
図11は、受信機側のレセプタクルRE2に関連する構成を示している。本技術の第2の実施の形態では、レセプタクル(又はプラグ)を正面から見た時に対角位置に存在するピンA1(GND)及びB1(GND)の両方に対してRF信号が供給される。前述したように、RF信号としてのアンテナ信号がプラグPL3のピンA1及びピンB1に対して供給されている。プラグPL3がレセプタクルRE2に順接続及び逆接続のいずれの場合でも、レセプタクルRE2のピンA1及びピンB1にRE信号が供給される。すなわち、表面及び裏面のどちらを上にしてもプラグPL3がレセプタクルRE2に挿入できるので、レセプタクルRE2のピンA1及びB1の両方からアンテナ信号が受信機に対して入力される。かかる第2の実施の形態は、第1の実施の形態と異なり、受信機側にRF信号を切り替えるためのスイッチを設ける必要がない。
上述した第2の実施の形態のピークアンテナゲインをシミュレーションにより求めた結果を図13A及び図13Bに示す。図13Aは、プラグをレセプタクルに順接続した場合のピークアンテナゲインであり、図13Bは、プラグをレセプタクルに逆接続した場合のピークアンテナゲインである。横軸は、地上波デジタルテレビジョン放送が行われている周波数帯域UHF(Ultra High Frequency )帯(470MHz~800MHz)を示している。縦軸がピークゲイン(dBd)を示す。dBdは、ダイポールアンテナとの比較の値である。(dBd=2.15dBi)の関係にある。dBiは、アンテナ利得(絶対利得)である。
図14は第2の実施の形態におけるケーブルの構成の他の例(プラグPL4)を示す。上述した変換ケーブルは、ジャック11とプラグPL3がケーブルを介して接続されている構成であるのに対して、プラグPL4はジャック11(検出スイッチ13)を有しない構成である。オーディオアダプタアクセサリーモードが認識されるために、プラグPL4のピンA5(CC)及びB5(VCONN)が互いにピンA12(GND)及びB12(GND)に接続される。
上述した第1及び第2の実施の形態は、単一のRF信号を伝送する例であるのに対して、第3の実施の形態は、複数のRF信号を伝送する場合に適用される。例えばダイバーシティ方式、MIMO(Multiple Input Multiple Output)のような複数のアンテナを用いる場合では、複数のアンテナ信号を伝送する必要がある。
図17は第3の実施の形態におけるケーブルの構成の例(プラグPL5)を示す。オーディオアダプタアクセサリーモードが認識されるために、プラグPL4のピンA5(CC)及びB5(VCONN)が互いにピンA12(GND)及びB12(GND)に接続される。プラグPL5には、ここでは、図示しないが、基板が接続されており、2本のアンテナ信号入力ライン21、22が、基板上に形成されている。この2本のアンテナ信号入力ラインを用いて、ダイバーシティを構成している。この基板上において、一方のアンテナ信号入力ライン21は、プラグPL5のピンB1に対して接続される。このアンテナ信号入力ライン21に、ここで図示しないが、直接受信したい周波数の約λ/4(λ:受信周波数の波長)のアンテナ素子を接続して、モノポールアンテナを構成している。他方のアンテナ信号入力ライン22は、プラグPL5のピンA1に対して接続される。このアンテナ信号入力ライン22に、ここで図示しないが、直接受信したい周波数の約λ/4(λ:受信周波数の波長)のアンテナ素子を接続して、モノポールアンテナを構成している。但し、両アンテナ素子の長さは、接続される機器によっても変わるので、必ずしもこの長さである必要はない。また、同軸ケーブルを介して直接アンテナ信号をプラグPL5に対して入力してもよい。すなわち、2本の同軸ケーブルの芯線がそれぞれのアンテナ信号入力ライン21、22に接続され、プラグPL5のA1とB1のそれぞれに対して接続される。図示しないが2本の同軸ケーブルのシールド線が対角線方向に位置するピンB1及びA1以外のGNDピンここでは、A12,B12に接続されて50Ω等のRFラインが構成される。また、2本同軸ケーブルのプラグPL5と反対端にそれぞれRFコネクタ例えばFコネクタが接続され、それぞれの外部のテレビアンテナと接続することも可能である。
図18は、受信機側のレセプタクルRE3に関連する構成を示している。本技術の第3の実施の形態では、レセプタクル(又はプラグ)を正面から見た時に対角位置に存在するピンA1(GND)及びB1(GND)のそれぞれに独立した二つのRF信号が供給される。
以上、本技術の実施の形態について具体的に説明したが、上述の各実施の形態に限定されるものではなく、本技術の技術的思想に基づく各種の変形が可能である。例えば、上述の実施の形態において挙げた構成、方法、工程、形状、材料及び数値などはあくまでも例に過ぎず、必要に応じてこれと異なる構成、方法、工程、形状、材料及び数値などを用いてもよい。例えば第2の実施の形態のレセプタクルRE2(図11)において、RF信号が供給されるピンA1及びB1を互いに接続するようにしてもよい。さらに、以上の説明では、USB Type-Cのインターフェースを通じてアナログオーディオ信号を伝送する例について説明したが、オーディオアクセサリー側にD/Aコンバータを設け、USB Type-Cのインターフェースを通じてデジタルオーディオデータを伝送する場合に対しても本技術を適用することができる。
