Abstract

本发明涉及一种无线传声器系统。本发明的一个目的是进一步开发这种无线传声器系统，同时本发明的另一个目的是改进高频发射器的互调间隔以便更多的发射器可以用在同一频带。所述目的通过以下一种无线传声器系统来实现，该系统包括与之相连的多个天线、与该天线或该多个天线相连的循环器和/或高频隔离器。

Description

包含高频发射器的传声器
技术领域
本发明涉及一种无线传声器系统。
背景技术
这样的无线传声器已经应用在许多不同方面。在那个方面可以关注Lectrosonics公司的目录，美国：超高频(UHF)无线传声器目录03/03，第4页，US 4 430 619和DE 2 226 515 A。
本发明的目的是进一步开发这种无线传声器系统。本发明的另一目标是提供一种对高频发射器的互调间隔的改进以便更多的发射器可以用在同一频带。
本发明并不局限于无线传声器系统，而是包括所有带有可移动天线的高频发射器。
在此，必须指出：已知高频循环器、隔离器或滤波器固定地安装在高频发射器或无线传声器中，其中高频发射器或无线传声器必须随频率改变适当地进行交换。显然该交换操作相当复杂和昂贵，并且还经常带来困难的技术问题。
发明内容
根据本发明，其目的通过一种无线传声器系统来得到。有利的发展在所附的权利要求中阐明。
根据本发明的一方面，提供了一种无线传声器系统，具有高频发射器，所述高频发射器包含：发射放大器；所述发射放大器的壳体；至少一个天线单元，具有天线和连接至所述天线的循环器或高频隔离器，所述循环器或高频隔离器将所述天线单元从所述发射放大器上去耦以保证所述发射放大器能够在恒定的操作范围内进行操作；所述天线和所述天线的循环器或高频隔离器被设置在所述天线单元的公共壳体中；及所述天线单元被调谐到给定频率范围或频率响应；其中所述天线单元可被插入所述发射放大器的所述壳体中或被拧在所述发射放大器的所述壳体上以使所述天线单元作为一个单元可被另一天线单元所替换，所述另一天线单元具有天线和循环器或高频隔离器且被调谐到给定频率范围或频率响应。
根据本发明，根据本发明的无线系统的天线或多个天线具有一个与其固定关联的循环器/高频隔离器或者连接到这样的循环器/高频隔离器，其中然后所述循环器/高频隔离器还可以分别配置在发射或接收装置中。但是如果天线可以插入地安装到发射或接收装置并且循环器/高频隔离器也被集成在天线中，那么就可以得到特别的优点。具体地，在这种情况下，全部天线被预调谐到一个期望的范围并且不需要后来再分别调整。如果是在集成天线(例如在手持无线传声器(手持发射器))的情况下，天线电性连接和机械连接到循环器/高频隔离器并且天线循环器/高频隔离器单元能够为一个完全的结构体被替换，这也是非常有利的。同样的也适用于接收装置。
循环器/高频隔离器通常分别在发射或接收方向具有低的传输衰减水平，而在发射或接收方向的相反方向具有高的阻塞衰减水平。循环器/高频隔离器的输入处的阻抗是恒定的并且与随后组件的阻抗无关。在这种方式下，在发射设备的情况中，保证了发射放大器能够在恒定的操作范围内进行操作。这样，例如在接触天线从而解调谐天线的情况下，导致对发射放大器或整个发射装置的较低反馈水平。通过循环器/高频隔离器将天线从发射放大器上去耦的一个基本优点在于两个相邻发射器仅仅仍然轻微地互相影响；发射器之间的互调被大大地降低。在这种方式下，多个发射器传声器能够在更窄的频率范围内以无干扰的方式来协同工作。从而提高了频率效率。在相反的情况下，利用同样的技术特征(互调产品)，发射器要操作的调谐范围可以提高。
根据本发明的天线和循环器/高频隔离器的可插入/可互换机械单元的解决方案，有可能将每个无线传声器与分配给各个工作频率范围的最佳天线组合相关联。那不仅应用于刚刚安装的无线传声器装置而且尤其应用于已经在操作中的系统。通过已经在操作中的无线传声器系统的翻新(retro-fitting)，由于在同样的安装中操作的相邻信道发射安装，有可能显著地降低其干扰。然后，另外的无线传声器可以在同样的频率范围中操作；其相当地提高了频率效率。其在带有许多传声器的无线传声器系统，如剧院/音乐舞台的情况下尤其重要。
如果具有不同方向特征如线性极化或圆形极化的天线要操作在无线传声器的预定发射放大器上，循环器的使用也非常重要。这里循环器/高频隔离器还允许从发射放大器高度去耦，从而提供最佳工作范围。根据本发明的解决方案，由于天线和循环器/高频隔离器的机械单元，允许两个组件的最佳匹配。在生产或随后在用户那里，由于可插入/可互换的天线循环器/高频隔离器单元，频率范围和/或天线特征可以容易地适应而没有任何问题。
对于手持发射器传声器(手持发射器)有两种配置：具有固定连接或可插入天线的手持发射器和具有集成在壳体中的天线的设计。同样可应用于插入式天线，如同应用于上述的袖珍发射器。对于具有集成在壳体中的天线的手持传声器，一种适当的设计配置是一种天线和循环器/高频隔离器在其中机械连接地布置在分离的联合壳体中。然后随频率变化而交换。
实质上，上述讨论还应用于无线传声器系统所需的接收器中。在这种情况下，接收器灵敏度水平或者(接收器)互调间隔也可以通过将循环器/高频隔离器结合进接收器的高频支路来提高。在这种情况下更多的接收器也可以操作在现有频率范围内，其中该频率范围通过利用发射器输出中的循环器/高频隔离器来适应上述的更多发射器的操作。在这种情况下频率效率也可以提高。
另一方面，通过在接收器的高频支路使用循环器/高频隔离器，有可能显著地扩大接收器的(可调谐)接收频带宽度。这提供给用户迅速适应在使用地所使用的频率的可能性。
利用根据本发明的(接收)天线循环器/高频隔离器的可插入/可互换机械单元的解决方案，除了接收器中的频率改变之外，用户只需要交换天线循环器/高频隔离器单元。这提供了对当前操作情形的迅速、简单的适应。
上述描述应用于包含通常在无线传声器系统中的袖珍接收器，还用于例如以耳内监听器系统形式应用于播送或音乐家的现场访谈中。在这种情况下，由于天线循环器/高频隔离器单元的互调的减少，多个无线系统还可以通过根据本发明的解决方案在同样的频率范围内操作。
本发明的特别的优点在于比至今为止更多的发射器可以实现在一个频带内，能够容易地实现频率的改变，并且甚至现有的高频发射器、发射装置以及无线传声器都能够被容易地翻新。
附图说明
以下将通过附图中所说明的实施例对本发明进行更加详细的说明。
图1显示了天线中设置有循环器(高频隔离器)的高频发射器的平面图；以及
图2显示了带有天线的传声器的视图，其中循环器和/或高频隔离器被设置在天线中以便各自的频带能够通过天线的替换被容易地设定。
具体实施方式
对于本申请中所描述的无线传声器系统，可以理解，这将不止应用于此，而且还可应用于具有天线的高频发射器中。
对于天线来说，外部地设置识别符将格外有利，该识别符与循环器和/或循环器单元的各个频率范围相关联。该识别符可以由诸如编码或彩色识别符构成，以便专家，这里指声音技术员或声音工程师，能够从一定距离以外非常容易地识别无线传声器的高频发射器所调谐的频率或其操作的频率。
循环器或高频隔离器还可设置有调谐装置以便在需要时将其调谐到给定频率范围或频率响应。
