將從會議參加者採集語f，並纟此語音信號上執行某些處 理。例如，對講機電話100上之麥克風（1〇2, 1〇4, 1〇6)將採 集會議參加者之語音以及來自對講機電話之擴音器（ιΐ2, 114)之聲音。對講機電話1〇〇將回應於對講機電話1〇〇之擴 音器（112, 114)取消或減小信號之振幅，以避免回音以及前 饋效應。然後，處理後之麥克風信號將被傳送至麥克風線， 進入行動電話140,就像該信號係直接來自一耳機受話器之 麥克風一樣。來自行動電話手機14〇之用於耳機之信號被提 供給對講機電話100。該信號還被進一步處理、放大，並接 著藉由對講機電話110上之擴音器112和114重播。就對講機 電話100而言，行動電話手機140正好係一用於經處理麥克 風信號之輸出以及一用於擴音器放大器之輸入。 雖然此新插口可能在機械上與某些先前技術之對講機電 活中出現之普通耳機又活器插口非常類似，但在電連接以 及功能上，此新插口與對講機電話之其他部分非常不同。 對於典型先#技術對講機電話耳機受話器插口，當耳機受 話器被插入插口時，該插口斷開並停用對講機電話中之麥 克風與擴音姦。對溝機電話充當一基礎機，而耳機受話器 充* 一耳機受話器。擴音器信號由對講機電話提供，並且 100756-950912.doc 11 1276345 麥克風信號被提供至對講機電話。 之下’ ^ 一類似插頭插入至此新插口内時，對講機 電忐中之麥克風和擴音器未被停用。對講機電話為已連接 之無線電話充當耳機受話器，而該已連接之無線電話充當 基座。利用此新插口，擴音器信號被提供至對講機電話内， 而麥克風信號由該對講機電話提供。 通常’在耳機受話器插入至耳機受話器連接器時，行動 電話手機停用手機上之麥克風及擴音器。該行動電話手機 可以自動地以機械或電子方式感測耳機受話器之存在。類 似地，當插頭插入至對講機電話之插口内時，對講機電話 將自動偵測來自行動電話手機之信號的存在，並可斷開與 陸上通彳§線路之連接。藉此方法，經由陸上通信線路至電 話網路之連接以及經由行動電話至電話網路之連接將不會 相互衝突。與行動電話手機類似，陸上通信線路鏈路或行 動電話鏈路之間之切換也可利用機械微型開關或電子邏輯 來自動進行。機械微型開關可以嵌入插口本身内。 現在，參考圖2，其描述了本發明另一具體實施例2〇〇。 此具體實施例200基本上與圖i所示之具體實施例1〇〇相 同’除對講機電話2〇〇未藉由一電纜250直接連接至陸上通 信線路260外。相反，藉由對講機電話2〇〇上之天線252與基 地台256上之天線254之間之無線電鏈路將對講機電話2〇〇 連接至陸上通信線路電話網路260。利用一電纜250，將該 基地台256直接連接至陸上通信線路電話網路260。對講機 電話100與基地台256之間之連接係許多射頻技術中之一。 100756-950912.doc -12- 1276345 δ亥射頻技術可為具有語音加密之2.4 GHz WDTC技術，或者 為900 MHz射頻連接。對講機電話2〇〇之其他所有功能與圖 所示相同。例如，對講機電話2〇〇具有相同之麥克風2〇2、 204寿206相同之擴音器212和214，電子模組220以及能藉 由電纜236以及插頭232和234連接至行動電話手機24〇之插 口 230。 仍然參考圖2所示之具體實施例，對講機電話200可由一 電池（未示出）供電，以便對講機電話200與電話網路之間不 存在線路。由於沒有線路之_，此對講機電話㈣可被放 置在會議室之任何地方。此對講機電話扇可具有附加插口 230’以便藉由行動電料機24()形成—無線連接4此情 況中，對4機電話扇不與基地台256進行通信。因而，利 用=行動電話手機及該電池供電電話，使得在行動電話可 以接至系統之任何場所進行高品質之電話會議。此外， ^無線手機㈣係—衛星電話，則在能夠看見天空之任何 i方都可以舉行全功能之電話會議。 ^藉由-行㈣話鏈路連接對講機電話 之電話會議即可獲得在對講機電話或行動電話上可^ 所有功能，特別係音頻處理。來自對講 獲传之 音頻信？卢偟…Z：、dL §之麥克風之 、。A ^至^端之前，被對講機電話中之立$ 器處理。根攄f +^ ^ T之曰頻處理 根據對錢電話上可獲得之功能 議之需求，可以勃片T U + 人付緣電話會 以執仃下列處理中之一或多個 合。一處理係聲波回音消除，Α 次者—些組 在一全雙工音频八允4進仃全雙工音頻會議。 曰頻會議中’會議參加者均可自然地講話並被 100756-950912.doc -13· 工276345

除了標準2.5毫米行動電話耳機受話器連接外，根據本發 明另一具體實施例，可以採用另一插口 /連接器。參考圖5， 此連接器可以係一四線連接器51〇。該四線或接觸係：一線 51丨用於電源，一線514用於接地，中間兩線512和513用於 資料信號。此連接器之一實例係標準USB連接器。現在， 許多行動電話不僅能夠傳送類比語音信號，而且還可以利 用數位信號藉由USB連接器與其他電子裝置（例如筆記型電 腦或個人數位助理）進行通信。 附加之USB連接器可使得易於將一行動電話連接至一對 講機電話’提供可用於傳達其他資訊的附加數位資料，例 如’控制資訊、帳務資訊、以及其他與在電話議會當中討 論之文件相關之資料。 本發明不僅可應用於窄頻帶手機，其還可以應用於寬頻 帶行動電話。 ' 在本申請案中’插座或插口係電子電路中之母接頭，其 與插頭結合使用，以便與另一雷 为電路形成連接。插頭係用來 形成連接之相應公接頭。—電纜可以具有兩個或兩個以上 插頭以及複數根線路，以便形成複數個電子路徑的連接。 此等插頭可以與圖4所示之相同，在圖4中兩個插頭均係標 準2.5¾米立體插頭。此等插 ’、 田具J以係不冋尺寸的，甚至不 100756-950912.doc 1276345 同類型，以便配合所連接之對講機電話及無線電話手機。 如上所述，根據本發明之具體實施例擴展了全功能對講 機電話之能力；使得在無線電話服務有效之任何場所均可 獲得這些功能；以及使得即使在沒有電服務或陸上通信線 路電話服務之情況下也可獲得這些功能。 雖然本發明之說明性具體實施例已經圖示出並進行了說 明，但應瞭解，在不脫離本發明之精神與範圍之情況下， 可以作出各種變化。 【圖式簡單說明】 當結合下列圖式考慮下列較佳具體實施例的詳細說明 時’可以對本發明更好的瞭解，其中·· 圖1描述了本發明一具體實施例，其中，使用一電話線將 對講機電話連接至一陸上通信線路。該對講機電話具有一 插口，藉此連接一無線電話手機，以便形成一連接至電話 網路之無線鏈路。 圖2描述了本發明之另一具體實施例，其中，藉由rF及一 基地台將對講機電話連接至一陸上通信線路，該基地台連 接至一有線電話網路。該對講機電話具有一插口，藉此連 接一無線電話手機，以便形成一連接至該電話網路之無線 鍵路。 圖3描述了 一與圖1類似之具體實施例，惟具有一附加電 纜除外。 圖4描述了一具有插頭之標準三線插口。 圖5描述了 一四線插口。 100756-950912.doc -16- 1276345 【主要元件符號說明】
