具体实施方式
下面结合附图对本发明的较佳实施例进行详细阐述，以使本发明的优点和特征能更易于被本领域的技术人员理解。在此需要说明的是，对于这些实施方式的说明用于帮助理解本发明，但并不构成对本发明的限定。
参照图1至图3所示，本实施例提供一种扬声器系统，具体为一种推-推结构的扬声器系统。该扬声器系统包括箱体1及设置于箱体1内的多个相互并联的低音扬声器2，至少其中两个低音扬声器2镜面对称设置。各低音扬声器2分别包括盆架21、设置于盆架21上的振膜22及用于带动振膜22振动的音圈23，各低音扬声器2的振膜22的正面相对设置，各振膜22之间形成有音腔3，音腔3连通至箱体1外，各盆架21位于相应的振膜22的背面和箱体1的内壁之间。各低音扬声器2还分别包括电容24，电容24和音圈23通过导线相串联。本发明中，“振膜的正面”是指振膜的距盆架和磁路系统较远的一侧表面，“振膜的背面”是指面向盆架和磁场系统且距盆架和磁炉系统较远的一侧表面。
具体如图1所示，本实施例中的扬声器系统包括两个相互并联的低音扬声器2，即两个低音扬声器2的正极相互连接，两个低音扬声器2的负极相互连接，且各低音扬声器2的音圈23分别串接一个电容24。两个低音扬声器2镜面对称设置，且两个低音扬声器2的振膜22的正面彼此相对，所述的音腔3位于两个振膜22的正面之间。
该扬声器系统包括固定设置于箱体1内的支架6。具体地，参照图2所示，支架6和箱体1的四周内壁通过螺钉相固定连接。各低音扬声器2均设置于支架6上，其盆架21的外缘固定连接于支架6，上述音腔3被支架6包围。支架6的上部形成有一个波导管4，该波导管4和音腔3相互连通从而和箱体1外界连通。即音腔3通过波导管4连接外界，从而将音腔3内的声音输出。并且，仅音腔3的一侧通过一个波导管4连通至箱体1外，即声音仅从一个波导管4中输出。箱体1上开设有一个用于设置波导管4的开口，其他部分则基本密封，波导管4的管壁41的一端部固定连接于箱体1的开口处，另一端部固定连接于各低音扬声器2的盆架21。上述的电容24具体位于相应的盆架21背面和箱体的内壁之间。
参照图4所示，分别对本实施例图1所示的扬声器系统和传统扬声器系统(包括两个相互独立的扬声器)进行了频率响应测试，并进行了比对。其中，浅色的频响曲线为本实施例图1所示的扬声器系统的频响曲线，深色的频响曲线为传统扬声器系统的频响曲线。由图4所示可知，本实施例图1所示的扬声器系统的低频响应高于传统扬声器系统。
本发明中，先将各低音扬声器2的音圈23分别与电容24串联连接，再将多个串联电容24后的低音扬声器2并联连接，通过波导管4输出，增加了低音扬声器2系统的效率，提高了低音扬声器2系统的低频输出，在不需要很大的箱体1的前提下，就能拥有很好的低频响应，且能有效提高扬声器系统的效率，从而增加低音扬声器系统的声压输出。
上述实施例只为说明本发明的技术构思及特点，是一种优选的实施例，其目的在于熟悉此项技术的人士能够了解本发明的内容并据以实施，并不能以此限定本发明的保护范围。
