Description

扬声器电话和使用其建立会议电话的方法
本专利申请要求2004年4月16日提交的相同发明人和相同标题的临时专利申请序列号60/562,782的优先权，在此将其引用。该专利申请涉及由Jed Wilson、Kate Nogarede和Greg Rousch转让给相同受让人的另一个专利申请，标题为“Method and Apparatus forVideoconference Interaction with Bluetooth-enabled CellularTelephone”，与该申请在同一日期提交，编号为199-0225US。
技术领域
本发明涉及一种扬声器电话，更具体地，涉及一种具有蜂窝电话连接的扬声器电话。
背景技术
电话已经成为通信的主要工具。根据对电话系列(family)的多种分类方式，存在许多类型的电话。电话可以使用陆地线路，可以是作为普通电话业务(POTS)线路，或者是例如综合业务数字网络(ISDN)线路的数字业务线路，也可以使用连到T1或PRI线路的到PBX的数字接口。电话可以使用无线通信连接到电话网络，并由此连接到另一个电话。公知的是，如果使用蜂窝网络连接到电话网络，则为蜂窝电话；如果通过卫星连接到电话网络，则为卫星电话。电话可以使用无线电波来连接到基站，基站利用陆地线路依次连接到电话网络。这就是典型的无绳电话。
电话可以包括手持机(handset)，它包括麦克风和送话器(earphone)。用户必须手持手持机并将其靠近头部，以便与电话网络的远端上的另一个用户进行交谈。许多电话具有免提选择，使用户不必手持手持机。头戴式送受话机(headset)是一种这样的选择，这是用于一对一私密交谈的较好选择。另一个选择是典型地扬声器电话(speakerphone)。在扬声器电话选择中，通过扬声器再现来自远端的语音。来自该扬声器的音量通常远大于手持机上的受话器或头戴式送受话机，因此许多人可以听到。该电话还具有能够接收近端用户的语音的麦克风。由于来自扬声器电话中的扬声器的声音能够到达扬声器电话中的麦克风，可能会产生正反馈。因此，扬声器电话不得不进行比常规电话更多的处理以使其可工作。扬声器电话可以工作在具有一些回波抵消作用的全双工模式中。在这种模式中，扬声器电话的临近用户能够听到远端用户的谈话，同时与他进行谈话。扬声器电话也可以工作在半双工模式中，此时只有一个人能够同时讲话和被听到。另一个人不能被听到，直到第一个人完全停止了讲话。这需要额外的处理，尤其是在全双工模式中，使得扬声器电话通常比没有扬声器电话功能的电话更加复杂并更加昂贵。允许进行免提电话交谈的能力使扬声器电话在某些场合中成为较好的选择。这种允许许多用户参加电话会议的能力使扬声器电话在许多场合中成为设备的必要部分，例如在商务活动中。实际上，在所有商业办公室的所有会议室安装了许多具有全功能(full-featured)的扬声器电话。
由于扬声器电话的复杂性，其通常更为笨重并且消耗更多电能。其通常设置在会议室的桌子上，与陆地线路和电源插座相连。扬声器电话不使用无线连接。这种不能使用无线连接限制了全功能扬声器电话的使用。
存在许多需要扬声器电话的其它场合，例如，在移动办公室或临时办公室中。在移动办公室或临时办公室中常常难以接入陆地线路，更难以添加更多的陆地线路，但是添加无线连接相对便宜和容易。在许多场合中，通过将无线电话手持机引入所在位置能够简单地进行添加无线连接。在没有发展陆地线路电话网络的世界上的许多地方，蜂窝或卫星连接是接入电话网络的唯一经济方式。在难以接入陆地线路的地方有使用扬声器电话需求。
现有解决该问题的一些尝试。一些卖主出售用于某些蜂窝电话的附件，以便将扬声器电话功能添加到这些特定蜂窝电话中。例如，CCMClip n Go附件可以向Motorola Vxx系列或Nokia 33xx系列的蜂窝电话添加扬声器电话功能。Dock‘N’Talk扬声器电话系统可以向Motorola StarTalk系列蜂窝电话添加扬声器电话功能。所有这些附件均为具有非常有限功能的低质量附件(add-ons)。其也许能够支持免提交谈，但通过蜂窝电话线路只能勉强地在电话会议中使用。因此，仍然需要制造可用于蜂窝电话用户的全功能的、能够进行会议的扬声器电话。
希望具有一种方法和设备，使其能够利用现已投入使用的大量的全功能扬声器电话并且使它们更有用。希望将全功能扬声器电话功能引入到陆地线路不能服务的位置。
发明内容
根据本发明的实施例使用了普通插座和电缆，将无线联接(linkage)添加到全功能扬声器电话中。还将使全功能扬声器电话能到任何能用无线电话手持机的地方使用。根据本发明的一个实施例，将插孔添加到扬声器电话。具有两个连接器的电缆用于连接一端处的扬声器电话和另一端处的无线电话。将电缆的一个连接器插入新的头戴式送受话机插孔中。将电缆的另一个连接器插入无线电话的头戴式送受话机连接器中。对于无线电话手持机，扬声器电话只是具有麦克风和受话器的一般头戴式送受话机。对于扬声器电话，无线电话手持机是用于已处理麦克风信号的出口和用于馈入扬声器的入口(inline)。
在一个实施例中，扬声器电话上的插孔是常用的三线头戴式送受话机插孔，一个电线触点对应三个信号中的一个信号：：麦克风信号、扬声器信号和地信号。
在另一个实施例中，扬声器电话上的插孔是标准插孔，例如USB插孔。
在另一个实施例中，扬声器电话是电池供电的扬声器电话。
附图说明
当结合附图考虑优选实施例的以下详细说明时，能够更好的理解本发明，其中：
图1示出了本发明的一个实施例，其中扬声器电话通过电话线(cord)与陆地线路相连。扬声器电话具有插孔，通过该插孔与无线电话手持机相连，以便与电话网络进行无线链接。
图2示出了本发明的另一个实施例，其中扬声器电话通过RF和基站与陆地线路相连，基站与有线电话网络相连。扬声器电话具有插孔，通过该插孔与无线电话手持机相连，以便与电话网络进行无线链接。
图3示出了与图1类似的实施例，除了附加电缆。
图4示出了标准三线插孔以及插头。
图5示出了四线插孔。
具体实施方式
根据本发明，将无线电话连接添加到基于陆地线路的扬声器电话。这一新的连接使现有扬声器电话更适用于难以发现陆地线路或陆地线路不能支持扬声器电话的区域。
参考图1，扬声器电话100通过电话绳150与陆地线路160相连。扬声器电话100可以具有多个麦克风(102，104，106)和扬声器(112，114)。尽管在图1所示的实施例中安装了两个扬声器(112，114)和三个麦克风(102，104，106)，但是只有一个扬声器和一个麦克风是必需的，安装任意数目的扬声器或麦克风都可以。扬声器电话100还具有与不同组件相连的电子模块120。该全功能扬声器电话100具有许多功能和能力。例如，可以具有常规电话小键盘、挂机/摘机、会议、静音、音量上/下键、菜单和导航键。还可以具有三个根据使用环境可调整的(context sensitive)自定义功能键，包括重拨、保持和可编程会议键。扬声器具有较大的频率响应范围，可以从300-4000Hz，或200-12,000Hz。控制台(console)麦克风可以具有类似的响应范围。扬声器电话可以有全双工的声响清晰度，使麦克风的拾取范围最高达9英尺的自动增益控制，具有智能麦克风混合功能和动态噪声减小功能的选通(gated)麦克风。具有这些大致性能的扬声器电话的实例是来自本申请的受让人Polycom Corp.的VTX 1000。
根据本发明的一个实施例，将新插孔130安装到这种扬声器电话100中。利用能够容纳三个有线插头132的这种插孔130，电缆136能够将扬声器电话100与手持机型蜂窝电话140相连。电缆136优选具有两个连接器132和134。每一个具有三线插头(132和134)。每一根电线承载不同的信号，一个用于麦克风信号，一个用于扬声器信号，并且一个用于公共或地信号。插头132或134之一设计用于与扬声器电话100中的插孔(130)相兼容。另一个插头134或132能够插入到蜂窝电话手持机140上的头戴式送受话机插孔(未示出)中。典型地，插孔130是2.5mm的蜂窝电话头戴式送受话机连接器，所述连接器从蜂窝电话提供输出以驱动头戴式送受话机受话器，以及从头戴式送受话机麦克风向蜂窝电话输入。对于蜂窝电话手持机140，扬声器电话100的作用如同只是具有麦克风和受话器的头戴式送受话机。扬声器电话100上的麦克风(102，104，106)拾取来自会议参加者的语音并对这种语音信号执行某些处理。例如，扬声器电话100上的麦克风(102，104，106)拾取会议参加者的语音和来自扬声器电话的扬声器(112，114)的声音。扬声器电话100会抵消或减小响应于扬声器电话100中扬声器(112，114)的信号的幅度，从而避免回波或前馈效应。然后，将已处理的麦克风信号发送到麦克风线路以进入蜂窝电话140中，如同信号直接来自头戴式送受话机中的麦克风。将来自蜂窝电话手持机140的用于听筒的信号提供给扬声器电话100。对该信号进行进一步处理、放大，然后通过扬声器电话100上的扬声器112和114进行重放。对于扬声器电话100，蜂窝电话手持机140只是用于已处理麦克风信号的输出和用于扬声器放大器的输入。
尽管该新插孔在机械上可能非常类似于在某些现有技术扬声器电话中出现的通用头戴式送受话机插孔，但是该新插孔对扬声器电话的其它部分而言，它的电连接和功能性方面有很大区别。对于典型的现有技术扬声器电话头戴式送受话机插孔，当将头戴式送受话机插入到插孔中时，插孔断开了扬声器电话中的麦克风和扬声器并使其不可用。扬声器电话充当基座，而头戴式送受话机充当头戴式送受话机。从扬声器电话提供扬声器信号，并且向扬声器电话提供麦克风信号。
相反，当将类似插头插入该新插孔中时，扬声器电话中的麦克风和扬声器并没有不可用。扬声器电话充当用于相连无线电话的头戴式送受话机，而相连的无线电话充当基座。利用该新插孔，将扬声器信号提供给扬声器电话，并从扬声器电话提供麦克风信号。
当将头戴式送受话机插入到头戴式送受话机连接器中时，蜂窝电话手持机通常使手持机上的麦克风和扬声器不可用。蜂窝电话手持机能够机械地或电子地自动感知头戴式送受话机的插入。类似地，当将插头插入扬声器电话的插孔中时，扬声器电话会自动地检测到来自蜂窝电话手持机的信号的存在，并断开与陆地线路的连接。按照这种方式，通过陆地线路到电话网络的连接和通过蜂窝电话到电话网络的连接不会彼此冲突。与蜂窝电话手持机相似，利用机械微型开关(micro-switch)或电子逻辑，可以自动进行陆地线路链接或蜂窝电话链接之间的切换。机械微型开关可以嵌入到插孔中。
现在参考图2，其示出了本发明的另一个实施例200。该实施例200实质上与图1所示的实施例100相同，除了扬声器电话200没有通过电缆250直接与陆地线路260相连以外。相反，扬声器电话200通过扬声器电话200上的天线252和基站256上的天线254之间的无线电链接与陆地线路电话网络260相连。基站256利用电缆250直接与陆地线路电话网络260相连。扬声器电话100和基站256之间的连接是多种射频技术之一。射频技术可以是具有语音加密的2.4GHzWDTC技术，或900MHz射频连接。扬声器电话200的其它所有功能与图1所示的相同。例如，扬声器电话200具有相同的麦克风202、204和206，相同的扬声器212和214、电子模块220以及能够通过电缆236和插头232和234与蜂窝电话手持机240相连的插孔230。
仍然参考图2所示的实施例，由电池(未示出)对扬声器电话200供电，因此在扬声器电话200和电话网络之间没有电线。可以将该扬声器电话200设置在会议室的任意位置，无需缠绕电线。该扬声器电话200具有附加插孔230，用于通过蜂窝电话手持机240进行无线连接。在这种场合中，扬声器电话200不与基站256进行通信。因此，利用蜂窝电话手持机和电池供电的扬声器电话能够在蜂窝电话能够连接到系统的任意位置进行高质量的会议电话。此外，如果无线手持机240是卫星电话，则能够在看得到天空的任意地方举行全功能电话会议。
一旦通过蜂窝电话链接连接了扬声器电话，则对于蜂窝电话会议，在扬声器电话或在蜂窝电话上可用的所有功能现在均可用，尤其是音频处理。在发送到远端之前，由扬声器电话中的音频处理器处理来自扬声器电话的麦克风的音频信号。取决于在扬声器电话上可用的功能和具体会议的需要，可以执行以下处理中的一个或多个或一些组合。一个处理是回波抵消，使得能够进行全双工音频会议。在全双工音频会议中，会议参加者能够完全自然地讲话，并且能够被蜂窝电话连接的另一侧上的人听到，而不是轮流讲话或冒在语句的中间被打断的危险。扬声器电话还可以开启动态噪声减小和补偿功能，以使背景噪声处于令人舒服的水平。第三附加处理可以是自动增益控制，以使要发送到远端的声音电平稳定并且可理解。第四处理可以是麦克风的动态选通。在多麦克风扬声器电话系统中，只有当某人向其讲话时，才选通或打开麦克风。当麦克风中只存在背景噪声时，则将其关闭，即，音频混频器忽略其信号。然后，混合所有的选通麦克风信号以形成音频信号。最终信号具有改进的信噪比。在具有无线电话链接的扬声器电话中可以采用许多其它的处理。上述四个只是用于演示目的的一些实例。
图3示出了本发明的另一个实施例。除了具有附加到扬声器电话300本身的电缆336以外，其与图1和图2中的实施例类似。在电缆336的另一端，有能够插入蜂窝电话手持机340的插头334。优选的插头是标准的2.5mm蜂窝电话头戴式送受话机连接器。在本实施例中，不需要有另外的带两个连接器电缆，这样在使用时，就不会丢失用于连接扬声器电话-蜂窝电话的电缆。
图4示出了标准2.5mm蜂窝电话头戴式送受话机连接器和电缆450、扬声器电话上的插孔430(扬声器电话未示出)和无线电话手持机440。有三条电线或三个触点来进行三种连接。一种连接针对一个信号，包括用于麦克风(431，441和451)的信号、用于扬声器(433，443，453)的信号和用于公共地(435，445，455)的信号。当将插头插入扬声器电话上的插孔430中时，用于麦克风和扬声器的触点431和433分别微微移动并机械地断开电话电缆(例如350)和扬声器电话(300)中的电子模块(例如320)之间的连接。
除了标准2.5mm蜂窝电话头戴式送受话机连接以外，根据本发明的另一个实施例，还可以使用另一个插孔/连接器。参考图5，该连接器可以是四线连接器510。四个线或触点是：一个511用于电源，一个514用于地，中间两个512和513用于数据信号。这种连接器的实例是标准USB连接器。现在，许多蜂窝电话不仅能够发送模拟语音信号，还能够利用数字信号，通过USB连接器与例如笔记本电脑或PDA的其它电子设备进行通信。
USB连接器的添加可以更容易地将蜂窝电话与扬声器电话相连，提供附加数字数据，其数字数据可用于传播其它信息，例如控制信息、帐单信息和与在会议电话期间讨论的文件相关的其它数据。
本发明不仅可以应用于窄带蜂窝电话，还能够应用于宽带蜂窝电话。
在本发明中，插座或插孔是电子电路中用于插头与其它电路进行连接的阴接头。插头是用于进行连接的对应阳接头。电缆可以具有两个或更多插头以及多条电线，从而对于多个电子路径进行连接。插头可以与图4所示的相同，其中两个插头均是标准2.5mm立体声插头。插头可以具有不同的尺寸，甚至不同类型，从而适合连接扬声器电话和无线电话手持机。
如上所述，根据本发明的实施例扩展了全功能扬声器电话的功能；使这些功能在无线电话业务可用的任何地方均可用；以及即使在没有电力供应或陆地线路电话业务的地方，也使这些功能可用。
尽管已经演示并说明了本发明的典型实施例，可以理解，对本发明可以进行各种修改，均不脱离本发明的精神和范围。
