实现本发明的最佳方式
图1为根据本发明的声音数据播放系统的第一实施例的功能方块图，请参照图1，声音数据播放系统包含两声音播放装置(为方便描述，两声音播放装置分别称之为第一声音播放装置10及第二声音播放装置20)。第一声音播放装置10包含第一射频电路11、第一播放电路12及第一控制电路13。第二声音播放装置20包含第二射频电路21及第二播放电路22。
第一控制电路13耦接于第一播放电路12与第一射频电路11之间，第二射频电路21耦接第二播放电路22，且第一射频电路11耦接第二射频电路21于第一控制电路13与第二播放电路22之间，且于第一播放电路12与第二播放电路22之间。
第一射频电路11发送一时间信息T，时间信息T对应于一声音数据的播放时间点，举例来说，以声音数据为一首时间长度为5分钟的音乐为例，时间信息T表示声音数据于5分钟内任意的播放时间点，例如，第0秒、第2秒、第42秒、第1分2秒、第2分22秒等；第二射频电路21接收第一射频电路11发送的时间信息T，第二射频电路21再将时间信息T传送至第二播放电路22，第二播放电路22在接收时间信息T后，第二播放电路22中储存有声音数据，第二播放电路22以时间信息T对应声音数据的播放时间点来播放声音数据，以前述时间信息T对应的播放时间点可为第42秒为例，第二播放电路22于声音数据的第42秒开始播放声音数据(即，第二播放电路22不播放声音数据于第42秒之前的声音片段)。
在一些实施态样中，时间信息T可为一默认值，由默认的时间信息T来控制第二播放电路22于声音数据的默认播放时间点开始播放声音数据。在实作上，第一控制电路13可为中央处理器、微处理器或微控制器，可藉由软件或固件控制第一控制电路13来产生时间信息T；或可将时间信息T预先储存在内存中，并藉由第一控制电路13传送至第一射频电路11。
在一些实施态样中，时间信息T对应声音数据于第一播放电路12中播放当下的播放时间点，也就是说，第一播放电路12中储存有声音数据，在第一射频电路11发送时间信息T之前，第一播放电路12正播放声音数据，第一控制电路13根据声音数据播放当下的播放时间点来产生时间信息T，第一控制电路13检测声音数据于第一播放电路12中播放当下的播放时间点，并根据声音数据播放当下的播放时间点来产生时间信息T，也就是说，第一控制电路13可实时地产生对应于声音信息的播放时间点的时间信息T，举例来说，当声音数据播放至第2秒时，第一控制电路13可据以产生对应于第2秒的时间信息T，并传送至第一射频电路11；此时，若第二射频电路21位于第一射频电路11的通讯范围内，第二射频电路21接收对应于第2秒的时间信息T，使第二播放电路22于声音数据的第2秒开始播放声音数据。如此一来，第二播放电路22与第一播放电路12可于相同的播放时间点同步播放声音数据。
在实作上，第一射频电路11包含第一天线111及调变模块112，调变模块112将第一控制电路13产生的时间信息T进行调幅或调频处理，第一射频电路11再藉由第一天线111来发送属于射频信号的时间信息T，第一天线111所发送的时间信息T的射频频率小于30MHz。第二射频电路21包含第二天线211及解调模块212，第二射频电路21藉由第二天线211接收属于射频信号的时间信息T，解调模块212将时间信息T进行解调以获得调幅或调频前的时间信息T，并将时间信息T传送至第二播放电路22。
第一控制电路13中包含计数器，计数器计数声音数据于第一播放电路12中当下的播放时间点，以产生一递增或递减的计数值来做为时间信息T，详言之，计数器可在第一播放电路12开始播放声音数据后以固定频率进行计数来产生计数值，例如，每64ms递增一次或递减一次。第二播放电路22在接收以计数值表示的时间信息T后，第二播放电路22可根据计数值对应的声音数据的播放时间来播放声音数据，详言之，第二声音播放装置20更可包含由多个开关或 多个多工器，第二播放电路22可藉由多个开关或多个多工器根据计数值来选择对应的音乐片段进行播放。举例来说，假设为5的计数值对应于声音数据的播放时间点为第5秒的音乐片段，第二播放电路22在接收时间信息T后即选择由第5秒对应的音乐片段开始播放声音数据。
在应用上，以声音数据为音乐为例，声音数据播放系统的设计者可在第一播放电路12与第二播放电路22中储存相同的音乐，使第二播放电路22在接收时间信息T后可与第一播放电路12同步播放同一音乐，且第一播放电路12及第二播放电路22可在音乐结束时同时停止播放；或者，第一播放电路12与第二播放电路22中可分别储存具有相同旋律但不同人声的音乐，使第二播放电路22在接收时间信息T后可与第一播放电路12同步播放具同一旋律的音乐。
图2为根据本发明的声音数据播放系统的第二实施例的功能方块图，请参照图2，第二实施例与第一实施例的差异在于，声音数据播放系统更包含射频标签30耦接于第一声音播放装置10，且第一射频电路11耦接于射频标签30与第一播放电路12之间，且第一射频电路11的输出端耦接第一播放电路12的输入端。
射频标签30用以储存一时间信息(为方便描述，称之为第一时间信息T1)，预存的第一时间信息T1对应于声音数据的播放时间点，第一射频电路11读取射频标签而接收第一时间信息T1，第一射频电路11将第一时间信息T1传送至第一播放电路12，播放电路12在接收第一时间信息T1后，第一播放电路12根据第一时间信息T1所对应的声音数据的播放时间点来播放声音数据，也就是说，第一播放电路12可由声音数据的任意起始位置开始播放声音数据。
在第一播放电路12根据第一时间信息T1开始播放声音数据后，第一控制电路13根据声音数据于第一播放电路12中播放当下的播放时间点来产生另一时间信息(为方便描述，另一时间信息称为第二时间信息T2)，第一射频电路11将第二时间信息T2发送至第二射频电路21，第二射频电路21将第二时间信息T2传送至第二播放电路22，第二播放电路22可根据第二时间信息T2所对应的声音数据的播放时间点来播放声音数据。
基此，假设第一时间信息T1对应的播放时间点为第0秒，第二时间信息T2对应的播放时间点为第20秒，第一播放电路12由声音数据的第0秒开始播放声音数据，第二播放电路22由声音数据的第20秒开始播放声音数据，换言 之，从声音数据的第20秒开始，第二播放电路22与第一播放电路12同步播放声音数据。
图3为根据本发明的声音资料播放方法的第一实施例的流程图，请同时参照图1及图3，首先，定义一时间信息(步骤S10)，时间信息对应于一声音数据的播放时间点，以第一射频电路11发送时间信息T(步骤S11)，以第二射频电路21接收时间信息T(步骤S12)，第二射频电路21将时间信息T传送至第二播放电路22(步骤S13)，使第二播放电路22以时间信息T所对应的声音数据的播放时间点播放声音数据(步骤S14)。其中，第一射频电路11所发送的时间信息的射频频率小于30MHz。
在一些实施态样中，时间信息T对应声音数据于第一播放电路12中播放当下的播放时间点，因此，在执行步骤S11之前，计数声音数据于第一播放电路12中播放当下的播放时间点以产生计数值以作为时间信息T，如此一来，第二播放电路22与第一播放电路12可同步地播放声音数据。
图4为根据本发明的声音资料播放方法的第二实施例的流程图，请同时参照图2及图4，定义一时间信息，称之为第一时间信息T1(步骤S20)，第一时间信息T1对应声音数据的播放时间点，以射频标签30储存第一时间信息T1(步骤S21)，以第一射频电路11读取射频标签而接收第一时间信息T1(步骤S22)，第一射频电路11将第一时间信息T1传送至第一播放电路12(步骤S23)，使第一播放电路12根据第一时间信息T1所对应的声音数据的播放时间点播放声音数据(步骤S24)。
在一些实施态样中，第一时间信息T1对应声音数据于第一播放电路12中播放当下的播放时间点，因此，在执行步骤S24之后，计数声音数据于第一播放电路12中播放当下的播放时间点以产生计数值以作为第二时间信息T2(步骤S25)，以第一射频电路11发送第二时间信息T2(步骤S26)，以第二射频电路21接收第二时间信息T2(步骤S27)，第二射频电路21将第二时间信息T2传送至第二播放电路22(步骤S28)，使第二播放电路22根据第二时间信息T2所对应的声音数据于第一播放电路12中播放当下的播放时间点来播放声音数据(步骤S29)。
图5为根据本发明的声音资料播放方法的第三实施例的流程图，请同时参照图1及图5，在本实施例中，欲播放的声音信息包含多个小节，各小节包含 音符、休止符、变音记号或前述项目的组合。基此，以第一射频电路11发送一小节信息(步骤S30)，小节信息可为一代码，而此代码可对应至前述声音信息的指定小节的音轨、音符、休止符、变音记号或前述项目的组合，也就是说，小节信息可对应至声音信息的一播放位置；并且，以第二射频电路21接收小节信息(步骤S31)，且第二射频电路21传送小节信息至第二播放电路22(步骤S32)，第二播放电路22以小节信息所对应的播放位置播放声音数据(步骤S33)。其中，第一射频电路11所发送的小节信息为射频信号，其射频频率小于30MHz。
在本实施例中，在执行步骤S33之前，声音数据播放方法更包含比对小节信息与声音数据的多个小节以获得小节信息所对应的播放位置，举例来说，以小节信息为代码为例，声音信息中的多个小节对应至不同的代码，分别比对小节信息对应的代码与各小节对应的代码以获得小节信息所对应的播放位置。
在一些实施态样中，小节信息对应声音数据于第一播放电路12中播放当下的播放位置，因此，在执行步骤S30之前，可计数声音信息于第一播放电路12中播放当下的小节来产生小节信息对应的代码，如此一来，第二播放电路22与第一播放电路12可同步地播放声音数据。
综上所述，根据本发明的声音资料播放方法可藉由射频电路发送时间信息，而此时间信息对应一声音数据的一播放时间点，使接收时间信息的播放电路根据时间信息所对应的任意播放时间点来播放声音数据，甚至是使不同的播放电路之间可同步播放声音数据，如此便提升生活上的便利性。
虽然本发明已以实施例揭露如上然其并非用以限定本发明，任何所属技术领域中具有通常知识者，在不脱离本发明的精神和范围内，当可作些许的更动与润饰，但这些更动与润饰均应包含于本发明所附权利要求的保护范围。
