由于扩音座 2作为扩音功能，所以由扬声器 23出来的音量会非 常大声， 麦克风 24收到此音量， 即会产生一共鸣信号。 控制器 21 将此共鸣信号通过内部模拟 /数字转换器转成第二数字信号，并与之 前所记录的第一数字信号相互做比对。 假如第二数字信号符合第一 数字信号时，控制器 21会将此第二数字信号抑制，进而达到消除共 鸣声音（ECHO) 的功能。 再配合图 5， 参考图 4， 本发明的扩音座 2进一步包括一功能键单元 28， 功能键单元 28 由电阻元件 R56、 R57连接开关 Sl、 S2所组成。该功能键单元 28连接于该控制器 21， 传送一控制指令 S2给该控制器 21 , 以提供音量大小的调整功能。
此外，本发明的控制器 21还可以通过车辆信号连接器 3与车辆 音响 7、 车辆发电装置 8做电性连接。 当本发明连接于车辆音响 7 时， 控制器 21可控制该来电信号 Sl， 使它被切换至该车辆音响 7， 以利用车辆音响 7达到双向语音传输及扩音功能。
再配合图 5，参考图 4，本发明的控制电路板进一步包括一充电 单元 26、一电池 25及一指示灯 27。充电单元 26由型号 BQ24010DRC 的集成电路连接电容元件 C47、 C48及电阻元件 R52、 R53、 R55、 R56所组成。 指示灯 27由电阻元件 R36、 R37连接发光元件 Dl、 D2所组成。 该电池 25连接于该控制器 21， 提供控制器 21用电。 充电单元 26连接该电池 25与该指示灯 27。当本发明连接于车辆发 电装置 8时，充电单元 26通过车辆信号连接器 3接受车辆发电装置 8送过来的电力，并根据该电力对该控制电路板上的电池 25进行充 电。 再参考图 4， 蓝牙耳机 1从远程接收来电信息 SI， 并且通过信 号传输端 10将来电信息 S1传送到扩音座 2的控制器 21。 控制器 21处理来电信息 Sl， 并且根据功能键单元 28输出的控制指令 S2， 以进行声音传输路径的切换。 根据控制指令 S2, 控制器 21可以切 换声音传输路径到扬声器 23与麦克风 24，而由扬声器 23与麦克风 24进行双向声音传输及扩音。 或者， 根据控制指令 S2, 控制器 21 可以控制切换声音传输路径到车辆音响 7， 而由车辆音响 7进行双 向声音传输及扩音。
综上所述， 本发明蓝牙耳机与扩音座的结合装置， 使用磁性吸 附原理， 以提供蓝牙耳机与扩音座快速结合以及快速定位。 当蓝牙 耳机 1接近扩音座 2时， 蓝牙耳机 1的可吸附件 12会被扩音座 2 的耳机容置槽 20两侧的磁性元件 22吸引， 而让蓝牙耳机 1快速的 被容置于耳机容置槽 20内， 同时达到定位的准确性。
此外， 蓝牙耳机 1与扩音座 2定位结合后， 蓝牙耳机 1的信号 传输端 10会与扩音座 2的控制电路板上的控制器 21电性连接。 此 时， 当蓝牙耳机 1从远程接收来电信息 S1时， 通过信号传输端 10 将来电信息 S1传送到扩音座 2的控制器 21。控制器 21处理来电信 息 Sl， 并且根据功能键单元 28输出的控制指令 S2， 以进行声音传 输路径的切换。 根据控制指令 S2， 控制器 21可以切换声音传输路 径到扬声器 23与麦克风 24， 而由扬声器 23与麦克风 24进行双向 声音传输及扩音。 或者， 根据控制指令 S2， 控制器 21可以控制切 换声音传输路径到车辆音响 7， 而由车辆音响 7进行双向声音传输 及扩音。
以上所述， 仅为本发明优选的具体实施例， 然而本发明的特征 并不局限于此， 所属领域的技术人员在本发明的领域内， 可轻易思 及的变化或修饰， 皆可涵盖在以下本发明的专利范围内。
