具体实施方式
以下，参照附图对本发明的实施方式进行说明。
首先对目前的便携式纯立体声音乐播放系统的现状做简单介绍。市场上有很多多发声单元立体声耳塞，有些耳塞在左右声道内各设置超过10个发声单元，声称多发声单元能改善耳塞的表现。但是，实际效果远未能达到，究其原因是左右声道耳塞各只有两条导线与播放机连接，各左、右声道耳塞内的所有发声单元都是并联的，各发声单元都接收同样的电信号，所以，发出的声音也基本相同，与只用一个发声单元的情况下差不多。
本申请发明是在便携式纯立体声音乐播放机上将左右声道各加上两个或者两个以上电子分频电路，每个电子分频电路的频率是连贯的，但是又是彼此独立的，即，用多个(即，两个以上)电子分频电路将左声道的输出音频进行分频，从而输出多个频率不同且频率依次连续的音频，此外，还可以有各自的增益控制，每个分频电路有独立电路经由多接点连接器输出，这些对于右声道也是同样的，此外，通常在播放机中所使用的多点连接器是阴连接器。在与便携式纯立体声音乐播放机配用的耳机内设置有与便携式纯立体声音乐播放机中的各电子分频电路分别对应的两个或者两个以上的具有不同频率响应特性的发声单元，各 单元(或者单元组)用独立的导线连接到多接点连接器，通常，耳机所使用的多点连接器是阳连接器。在使用时，耳机的多点连接器插入到播放机的多点连接器中，从而将二者连接起来。耳机的多接点连接器和播放机的多接点连接器在频率上是对应的，播放机内有多少个电子分频电路，耳机内就有多少个不同频段的发声单元，这样，耳机内的每个发声单元(或单元组)接收的是相应频段且强弱可控的电信号，发出相应频段声音。此外，上述的耳机还可以是耳塞式耳机。
本申请发明的便携式纯立体声音乐播放系统的播放机上有多少段分频输出电路，耳机(例如，耳塞式耳机)内就有多少个与这些分频输出电路一一对应的相应频段的发声单元(或者单元组)，各发声单元用独立的导线经多接点连接器连接到播放机的相应频段的电路输出端。
在图2中示出了3分频便携式纯立体声音乐播放系统的情况。具体地，在图2所示的便携式纯立体声音乐播放系统中，播放机的输出为共地式，播放机在左声道具有三个电子分频电路，对左声道进行高音分频、中音分频以及低音分频并且分别输出高频、中频以及低频频段的声音，此外，分别利用高频放大器、中频放大器以及低频放大器对被分频后的高频、中频以及低频频段的声音进行放大，高频放大器、中频放大器以及低频放大器的输出可经由播放机所具备的7接点连接器向外部输出，即，高频放大器、中频放大器以及低频放大器的输出连接于7接点连接器(连接器为阴连接器)，在图2所示的情况下是播放机的7点连接器与耳机的7点连接器(相应地，连接器为阳连接器)相连接而将播放机的左声道与左声道耳机连接，并且，高频放大器、中频放大器以及低频放大器输出的高频、中频以及低频频段的声音分别被输入到左声道耳机的高频发声单元(或者单元组)、中频发声单元(或者单元组)以及低频发声单元(或者单元组)。此外，关于右声道，也是与左声道的情况同样地，播放机在右声道具有三个电子分频电路，对右声道进行高音分频、中音分频以及低音分频并且分别输出高频、中频以及低频频段的声音，此外，分别利用高频放大器、中频放大器以及低频放大器对被分频后的高频、中频以及低频频段的声音进行放大，高频放大器、中频放大器以及低频放大器的输出可经由上述的7接点连接器向外部输出，即，高频放大器、中频放大器以及低频放大器的输出连接于上述的7接点连接器，在图2所示的情况下是播放机的7点连接器与耳机的7点连接器相连接而将播放机的右声道与右声道耳机连接，并且，高频放大器、中频放大器以及低频放大器输出的高频、中频以及低频频段的声音分别被输入到右声道耳机的高频发声单元(或者单元组)、中频发声单元(或者单元组)以及低频发声单元(或者单元组)。
