由于电子科技的进步与高度的普及化， 一般人在日常生活中都会与各 种不同的电器设备接触， 并操作这些设备， 由于利用遥控技术， 人们只需 要执行简单的按键动作， 即可在稍远处直接遥控这些电器设备执行各种动 作， 例如： 电视、 影音播放机、 音响、 冷气机等家电， 另如车库车门、 汽 车防盗及家庭防盗等等亦广泛运用遥控技术， 由此可见， 一般人对于遥控 器倚重之深。 但由于遥控技术的普遍应用， 一般家庭光是家电用品可能就 有数个遥控器， 无形中已造成遥控器泛滥的现象， 对于使用者而言是十分 困扰的， 因此， 简化与整合遥控器是一个亟待解决的问题。 发明内容
本发明主要目的在提供一种可有效解决目前遥控器泛滥问题的整合 型遥控装置， 其可利用普及率极高的有线或无线话机作为各种遥控信号共 同输入接口， 并利用音频辨识配合既有遥控技术， 以达成单一设备遥控多 个受控设备的目的。
为达成上述目的釆取的主要技术手段是令所述遥控装置至少包括有 一音频解码发射器， 其设于话机的特定距离以内， 以便接收使用者按下话 机按键时所产生的音频信号（DTMF) , 并将其转换为遥控信号予以发射， 而 该音频解码发射器包含：
一拾音器， 其用以接收话机产生的音频信号；
一 DTMF 解码器， 其输入端连接前述拾音器， 以便将音频信号转换为 对应的数字信号；
一微控制器， 其用以将 DTMF 解码器送出的数字信号转换为特定的遥 控密码；
一放大暨发射电路， 其设于微控制器的输出端上， 用以对其输出的遥 控密码载上载波后予以发射；
由于所述音频解码发射器具有音频辨识及密码转换功能， 当使用者在 话机上按下特定的按键后， 其因按下按键所产生的音频信号将为拾音器所 接收， 经解译为数字信号， 再由微控制器转换成一组密码予以发射， 即可 遥控一对应的受控设备； 换言之， 使用者利用话机输入的每一组数字分别 代表一组密码， 而不同的密码即可分别遥控不同的受控设备， 尽管如此， 却未增加遥控器的数目， 故可达到简化与整合的目的。 附图说明

26 指示灯 27 蜂鸣器 具体实施方式
首先请参阅图 1所示， 主要是令一音频解码发射器 1 0邻近一话机在 一特定距离以内 （如 1 0公分以内） ， 为方便使用， 可将音频解码发射器 10与话机 100结合在一起， 其一种可行方式是将该音频解码发射器 10以 胶合方式结合在话机 1 00的背面，由此，当话机 100因按键按下而产生 DTMF 音频信号时， 即可为该音频解码发射器 1 0所接收， 另一种方式如图 2所 示， 当话机 1 00是置放于一话机护套 1 01内时， 则前述音频解码发射器 1 0 可直接置入话机护套 101 内即可。 以上所述， 仅为该音频解码发射器 10 与话机 100结合的少数方式而已， 而前述方式仅为少数实施方式的呈现而 已， 非用以限制特定的实施方式。 又前述话机 1 00可为有线或无线话机， 其中无线话机又可为一般家用的市话无线话机或行动电话， 本实施例图中 所示者即为一行动电话。
由于话机 100上的按键被按下时， 将产生一符合 DTMF标准的音频信 号（一般称为 TONE音）， 不同按键其按下所产生音频信号的频率亦不相同， 本发明即利用此项特性， 以话机 1 00作为遥控指令的输入接口， 并以不同 组合的数字组代表不同的遥控指令， 而由音频解码发射器 10接收后转换 为特定的遥控密码， 并传送予受控设备的接收器， 以达成遥控执行特定功 能的目的。 至于音频解码发射器 10的电路构造请参阅图 3所示, 其包括有： 一拾音器 11， 由一般所称的微音器或麦克风 (MIC)构成， 其用以接收 前述话机 1 00上按键按下时产生的 DTMF音频信号；
一 DTMF解码器 12， 其输入端是通过一放大器 1 3连接前述拾音器 11， 以便将音频信号先经过放大后再转换为对应的数字信号；
一^ 空制器 14 , 其主要构成包含一功能控制器 1 41及一编码器 142 , 而由功能控制器 141将 DTMF解码器 12送出的数字信号转换为特定的遥控 密码， 再由编码器 142进行编码后送出；
一放大暨发射电路 15 , 其设于微控制器的输出端上， 用以对其输出的 遥控密码载上载波后予以发射； 其可采用红外线调制或射频（RF)调制。
又请参阅图 4所示， 是前述音频解码发射器 1 0的 细电路图， 该微 控制器 14并与一内存 16连接， 以储存的预设的遥控密码； 另于本实施例 中， 该放大暨发射电路 15的发射部分采取射频（RF)方式调制。
利用前述音频解码发射器 1 0 的音频辨识及密码转换功能， 当使用者 在话机 100上按下特定的按键后， 其因按下按键所产生的音频信号即为前 述拾音器 11所接收， 经放大后由解码器 12解译为数字信号， 再由微控制 器 14转换成一组密码予以发射， 即可遥控一对应的受控设备。
至于受控设备的接收部分除可为其本身所设的接收器外， 也可为一独 立的接收解码器， 该电路构造首先请参阅图 5所示， 其包括有：
一接收暨放大电路 21 , 其用以接收前述音频解码发射器 1 0发射的遥 控信号， 并作信号放大处理；
一微控制器 22 , 主要由一解码器 221及一功能控制器 222组成， 其中 解码器 221是对前述接收暨放大电路 21输入的遥控信号进行解码， 随后 解码完成的数字信号送至功能控制器 222产生执行特定控制功能的输出信 号；
一接口电路 23 , 其设于微控制器 22的输出端上， 用以与受控设备连 结， 以便输出控制信号至受控设备执行特定的驱动或控制动作。
又请参阅图 6所示， 是前述接收解码器的详细电路图， 其中， 该微控 制器 22又与一内存 24连接， 以储存预设的密码与控制信号； 又微控制器 22于特定接脚上分设有一开关 25、 一指示灯 26及一蜂呜器 27， 其中， 开 关 25是用于切换一般使用状态或学习状态， 蜂鸣器 27是在开关 25切换 时产生声响， 又指示灯 26则在指示工作状态。
由上述说明可看出本发明的具体电路构造与工作原理， 其主要特色在 于利用音频解码发射器的特殊设计， 利用目前已人手一机而高度普及的手 机或一般家用话机作为共同的输入接口， 再利用使用者由话机输入的每一 组数字分别代表一组密码， 以不同的密码分别遥控不同的受控设备， 由此， 可在不增加遥控器数目的前提下， 达到遥控多个受控设备目的， 并有效解 决目前遥控器泛滥的问题。
