本发明实施例提出了一种天线，包括：压电陶瓷喇叭的电极、高通滤波器；
其中，压电陶瓷喇叭的电极包含有射频信号馈点，射频信号馈点与射频电路相连；高通滤波器的一端与射频电路相连，另一端和射频信号馈点相连。

可选的，还包括：低通滤波器；
压电陶瓷喇叭的电极还包括电极信号馈点；
所述低通滤波器的一端与所述电极上的电极信号馈点相连，另一端与音频输出电路相连。
本发明实施例还提出了一种终端，所述终端包括如上所述的天线。
与相关技术相比，本发明实施例的技术方案包括：压电陶瓷喇叭的电极、高通滤波器；其中，压电陶瓷喇叭的电极包含有射频信号馈点，射频信号馈点与射频电路相连；高通滤波器的一端与射频电路相连，另一端和射频信号馈点相连。上述方案中，通过压电陶瓷喇叭的电极来实现天线，由于压电陶瓷喇叭同时能实现音频功能，因此，天线不需要专门占用一定的结构空间，提高了空间使用率。

附图概述
图1为本发明实施例天线的结构组成示意图。
本发明的实施方式
为了便于本领域技术人员的理解，下面结合附图对本发明实施例作进一步的描述，并不能用来限制本发明的保护范围。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的各种方式可以相互组合。

其中，压电陶瓷喇叭的电极包含有射频信号馈点，射频信号馈点与射频电路相连；高通滤波器的一端与射频电路相连，另一端和射频信号馈点相连。
通过本发明实施例的方案，通过压电陶瓷喇叭的电极来实现天线，由于压电陶瓷喇叭同时能实现音频功能，因此，天线不需要专门占用一定的结构空间，提高了空间使用率。
其中，如图1所示，压电陶瓷喇叭包含有陶瓷材料(具有压电效应的单晶体或多晶体材料)和两个电极(即涂在陶瓷材料两个面上的两个金属导电层)。当在两个电极上施加音频电信号时，相当于给陶瓷材料的两端施加了一定的电压，这时，由于陶瓷材料的压电效应而产生机械应力变化，从而发出声音。
其中，射频信号馈点不同于电极信号馈点。
可选的，还可在音频输出电路和压电陶瓷喇叭的电极上的电极信号馈点之间连接低通滤波器。低通滤波器设置为让音频信号无衰减的通过，同时隔离射频信号，使得射频信号的能量不会衰减，保证天线功能的实现，又不影响音频功能。具体如何实现低通滤波器属于本领域技术人员的公知技术，并不用于限定本发明的保护范围，这里不再赘述。
其中，高通滤波器设置为让射频信号无衰减的通过，而隔离音频信号，使得音频信号不会对射频信号产生干扰，提高了天线的精度。具体如何实现高通滤波器属于本领域技术人员的公知技术，并不用于限定本发明的保护范围，这里不再赘述。

其中，接地馈点不同于电极信号馈点和射频信号馈点。
其中，射频信号馈点和接地馈点的具体位置可以根据实际的设计和仿真来进行调整。
本发明实施例还提出了一种终端，包括如上所述的天线。
以上内容是结合具体的实施方式对本发明所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明。
上述实施例中的各装置/功能模块/功能单元可以采用通用的计算装置来实现，它们可以集中在单个的计算装置上，也可以分布在多个计算装置所组成的网络上。
