Description

免提车载安装套件
技术领域
本发明涉及一种用于移动电话的免提车载安装套件,所述移动电话通过短程通信链路,如蓝牙型短程通信链路,连接至耳机,所述安装套件包括位于盒内的通信单元,该盒连接至电源,如车辆内的12V插座端子,所述盒具有支座或固定件,可以将耳机放置在其中并连接至所述通信单元,所述盒包括扬声器和麦克风,其中,在支座或固定件内提供至耳机的电连接。
背景技术
“FreeTop”公司公开了类似的车载安装套件。该公知的车载安装套件由具有独立的蓝牙无线模块的通信单元组成,可以将耳机安装在该通信单元内,从而可以通过汽车的12V插座端子对其充电。当耳机安置在支座上时,耳机被关闭,由通信单元取代耳机的功能。
因此,在该系统内,耳机和通信单元是两个分离的单元,每个单元有各自独立运行的蓝牙无线模块,但是,如上所述,当耳机被放置在通信单元的支座上时,耳机被关闭。
应注意,在开车时,在耳朵上戴耳机的用户当然把移动电话作为免提装置来进行操作,但是,经过长距离、长时间之后,即使目前的耳机是用轻型材料制成的,在耳朵上戴耳机无疑会使人感到有负担。
专利文献GB2277422A公开了一种免提车载安装套件。所述安装套件包括位于盒内的通信单元,该盒连接至电源,如车辆内的12V插座端子,所述盒具有支座或固定件,可以将所述耳机放置在其中并连接至所述通信单元,所述盒包含扬声器和麦克风,其中,在所述支座或固定件内提供至所述耳机的电连接。
发明内容
本发明的一个目的是提供一种包括耳机的免提车载安装套件,具有无源元件,结构比较简单,同时保持上述免提套件相同的舒适度。
通过本发明的免提车载安装套件来实现本发明的目的,该免提车载安装套件的特征在于通信单元包含无源元件,当耳机放置在支座上时,这些无源元件受耳机的电路控制,无源元件包括扬声器和麦克风。
这里,所述通信单元可以由无源元件组成,这些无源元件可以由与耳机结合的电路来控制。但是,应注意在该连接中,没有任何东西阻碍由所结合的放大器来放大扬声器的信号。
本发明通信单元的连接优点在于耳机里含有开关电路,该开关电路适于切换所述耳机的所述电路,当耳机放置在支座内时,用于使所述电路连接至通信单元的扬声器和可选麦克风,或当从支座上取下耳机时,用于使所述电路连接至耳机的麦克风和扬声器。
根据本发明,耳机的电路是具有蓝牙无线模块的数字信号处理器,该蓝牙无线模块可选地包括降低噪音电路,保证在所述移动电话和所述通信单元之间的最佳声音质量。
所述降低噪音电路包括回音衰减电路,当所述耳机放置在所述支座上时,所述回音衰减电路适于连接至所述通信单元。
所述耳机具有多个控制旋钮,如音量控制、打开/关闭开关、功能开关,当所述耳机放置在所述通信单元的所述支座上时,这些旋钮的功能控制所述通信单元。
附图说明
下面将参照附图更详细地说明本发明,其中,
图1示出了根据本发明的所结合的各单元;
图2说明了图1所示各单元之间的连接。
具体实施方式
在图1中,标号1表示根据本发明的通信单元,其由盒组成,在该盒内结合了扬声器2和麦克风5。此外,通信单元配置有插头3,其优选为用于汽车点烟器的12V插头。
所述盒可以可选地包括放大器(未显示),用于放大扬声器信号。
从图1中还可以看到,耳机4设置在盒内的支座上,所述耳机装配有麦克风10和扬声器9以及公知的电路。
此外,支座包括与耳机的双线电连接,用于把耳机所接收到的信号传输给通信单元的扬声器;并且,如果通信单元配备有麦克风,支座还包括与耳机的双线电连接,用于把通信单元所发送的信号传输给耳机。此外,支座包括用于给耳机充电的双线。
最后,图1示出了能够通过蓝牙型的短程通信链路与耳机4进行通信的移动电话6。
下面将参考图2说明图1中的各单元之间的连接。
为了清晰明了,在耳机的外部,按包括蓝牙无线模块的数字信号处理器7的形式示出了包含在耳机内的电路。
当耳机放置在支座或固定件上时,该数字处理器检测把耳机连接至通信单元1的线路8。现在,数字信号处理器影响开关电路11,开关电路11也可以合并在耳机内,这样,通信单元的扬声器2和可选麦克风5连接至耳机,而耳机的扬声器9和可选麦克风10被关闭。
如图2所示,开关电路有两对开关,S1和S2以及S3和S4。当开关位于图2中所示的位置时,通信单元连接至耳机的所述电路,开关S1和S2断开,开关S3和S4闭合,从而通过耳机的蓝牙无线模块连接至移动电话6。
如果从通信单元取下耳机,则开关S1和S2闭合(如虚线所示),同时开关S3和S4断开(如虚线所示),从而使耳机作为普通的耳机使用。
