现在将参照附图来详细描述本发明的各种示例性实施例。应注意到：除非另外具体说明，否则在这些实施例中阐述的部件和步骤的相对布置、数字表达式和数值不限制本发明的范围。
以下对至少一个示例性实施例的描述实际上仅仅是说明性的，决不作为对本发明及其应用或使用的任何限制。
对于相关领域普通技术人员已知的技术、方法和设备可能不作详细讨论，但在适当情况下，所述技术、方法和设备应当被视为说明书的一部分。
在这里示出和讨论的所有例子中，任何具体值应被解释为仅仅是示例性的，而不是作为限制。因此，示例性实施例的其它例子可以具有不同的值。
应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步讨论。
本发明提供了一种用于扬声器的后盖。参照图1-3，该后盖包括：后盖本体1和连接组件2。其中，后盖本体1的一边设有第一连接部101。第一连接部101一般是由后盖本体1的一边向外延伸而成。为使加工方便并节省空间，在本发明的一种实施方式中，参照图3，后盖本体1的一边向外延伸并向下弯折成直角形成第一连接部101。这样，第一连接部101位 于扬声器的侧面，连接组件2设于侧边，节省了高度方向的空间，适于待安装设备轻薄化的要求。当然，弯折的角度可以根据需要进行选择，而不限于直角。第一连接部101也可以单独制作，然后连接到后盖本体1上，本发明对此不做限定。
通常情况下，后盖本体1单独制造。后盖本体1为片状，其材质为金属。优选的实施方式是，后盖为不锈钢材质。考虑到长期使用时，不锈钢也会生锈，更加优选的方式是，在后盖的表面镀一层镍金属，以延长后盖的使用寿命。后盖的厚度为0.15-0.2mm。当然，后盖的形状和材质可以根据需要进行选择，只要满足强度要求以及耐用性要求即可，本发明对此不做限定。
使用时，参照图5，后盖安装到中盖3的一侧。后盖的平整度以及加工的尺寸应具有设定的加工精度，以保证其安装到中盖3上后密封性良好。为了确保平整度以及尺寸的加工精度，在本发明的一种实施方式中，后盖本体1采用冲压成型的方式，将不锈钢片一体冲压成型。后盖与中盖3的连接方式可以为卡接，即在中盖3的侧壁的内侧设有卡槽，安装时，将后盖的边缘嵌入卡槽即可。当然，根据需要，连接方式也可以采用其他方式，如粘接等。
参照图2，连接组件2设有相互连接的第一表面和第二表面。连接组件2的材质采用金属，优选的实施方式为，连接组件2为不锈钢、铜合金或者铝合金。当然，根据需要，连接组件2也可以采用其他材质，如塑料、塑胶或者硅胶等。为了使加工方便并节省空间，在本发明的一种优选的实施方式中，第一表面与第二表面垂直，连接组件2采用冲压成型工艺加工而成。当然，根据需要，第一表面与第二表面可以呈设定角度，本发明对此不做限定。第二表面设有第二安装部，连接组件2通过第二连接部203与后盖本体1的第一连接部101连接。第一连接部101与第二连接部203之间的连接方式为焊接、铆接或者弹性接触连接。
为使连接更加稳固，参照图4，在发明的一种实施方式中，连接方式为弹性接触连接。由第二连接部203的相对的两侧弯曲并延伸，以形成“U”字形结构。“U”字形结构的开口可以是水平或者竖直，也可以成其他角度。 第一连接部101设有相对的第一外壁和第二外壁，第一外壁与第二外壁的之间距离大于“U”字形结构的两条边之间的距离。为了加工方便，第一连接部101为矩形，该矩形相对的两条边为第一外壁和第二外壁。“U”字形结构的两条边夹在第一外壁与第二外壁的外侧，形成设定的夹紧力，以使连接稳固。当然，第一连接部101的也可以为柱形，或者其他形状，只要具有相对设置的第一外壁和第二外壁，并且第一外壁与第二外壁的之间距离大于“U”字形结构的两条边之间的距离，以使“U”字形结构的两条边能夹住第一外壁与第二外壁的外侧即可，本发明对此不做限定。
可选择地，在发明的另一种实施方式中，连接方式为弹性接触连接。由第一连接部101的相对的两侧弯曲并延伸，以形成“U”字形结构。同样地，“U”字形结构的开口可以是水平或者竖直，也可以成其他角度。第二连接部203设有相对的第一外壁和第二外壁，第一外壁与第二外壁的之间距离大于“U”字形结构的两条边之间的距离。为了加工方便，第二连接部203为矩形，该矩形相对的两条边为第一外壁和第二外壁。“U”字形结构的两条边夹在第一外壁与第二外壁的外侧，形成设定的夹紧力，以使连接稳固。当然，第二连接部203的也可以为柱形，或者其他形状，只要具有相对设置的第一外壁和第二外壁，并且第一外壁与第二外壁的之间距离大于“U”字形结构的两条边之间的距离，以使“U”字形结构的两条边能夹住第一外壁与第二外壁的外侧即可，本发明对此不做限定。
进一步地，第二表面还设有限位装置204。该装置用于固定多股线缆206的位置，以防止待安装设备使用过程中，线缆206任意移动，造成绝缘皮划破或者造成其他元件松动，而损坏设备。为了加工简单和使用方便，参照图3，在本发明中，限位装置204的横截面为“C”字形。使用时，线缆206从“C”字形限位装置204的开口处放入，依次放入多股线缆206。该装置可以有效地固定多股线缆206的位置。为了避免线缆206安装时开口处划伤线缆206的绝缘皮，开口处的边缘弯折180°，使开口处与线缆206接触的地方变平滑，以免造成划伤。
更进一步地，参照图2，连接组件还设有触点，第一表面延伸并弯曲，以形成触点201，弯曲的方向可以根据需要进行设计。该触点201可以用 于扬声器与其他元器件的电连接，为了保证电连接的可靠性，触点201设有导体。连接时，线圈的导线与外界的导线在触点201处连接，可以采用锡焊的方式将待连接的导线焊接到触点201上，由于触点201上导体的存在可以有效地实现电连接。当然，连接方式不限于焊接，也可以采用其他方式，如接触式电连接，只要能保证电连接的有效性和稳定性即可，本发明对此不做限定。
为保证导体与触点201接触面积大且连接牢固，在本发明的一种实施方式中，导体通过电镀或者化学镀的方式设于触点201。分体式的设置方式还可以避免电镀或者化学镀时，污染后盖本体1。导体的材质为材质为金、锡或者镍中的一种。当然，导体也可以采用其他方式设于触点201，只要该连接方式能保证足够的连接稳定性即可，本发明对此不做限定。此外，导体的材质也可也为其他金属，只要能保证导电性能良好即可。
参照图2-3，为了便于扬声器与待安装设备的连接，如手机、平板电脑或者智能手表等待安装设备，第一表面还设有连接孔202。在本发明的一种优选的实施方式中，连接孔202内设有内螺纹，连接孔202还安装有与内螺纹配合的螺钉205。安装时，将连接孔202与待安装设备的安装孔对准，连接孔202位于安装孔的下面；然后，把螺钉205穿过安装孔，再旋紧至连接孔202即可，安装十分方便。当然，连接孔202也可以不设置内螺纹，而采用螺栓连接的方式，将扬声器通过连接孔202安装到设定位置的安装孔中，本发明对此不做限定。
此外，连接孔202还可以具有电连接的功能，在本发明的又一种实施方式中，连接组件2的材质为铜合金或者铝合金。铜合金或者铝合金具有良好的导电性能。通过与外界导线的连接，可以实现扬声器内部电路与外界电路的电性导通。连接时，将连接组件2与扬声器内部电路的导线，如音圈的导线，与连接组件2相连接；然后，将外界电路的导线的电缆接线片，即线鼻子，或者馈电点的安装孔与连接孔202用螺钉205或者螺栓进行电连接，即可实现扬声器内部电路与外界电路的电性导通。连接十分方便。
为了加工制造方便，后盖本体1和/或连接组件2分别采用一体成型 的加工工艺，如，通过一块板材一体冲压成型。加工时，第一连接部101与第二连接部203的结构应当相互匹配，以便于连接。分别成型后，再将后盖本体1的第一连接部101与连接组件2的第二连接部203进行连接，即形成本发明提供的后盖。此外，冲压成型工艺可以根据需要制造出结构复杂的连接组件。加工十分方便，而且由于采用分体式制造，使得加工工序减少，加工难度降低，进而提高了成品率。
本发明提供的用于扬声器的后盖，设有后盖本体1和与后盖本体1相连接的连接组件2，该组件包括设有导体的触点201、连接孔202以及限位结构。该触点201用于扬声器与外界的导通；该连接孔202用于扬声器的固定或者用于扬声器与其他元器件的导通；该限位装置204用于线缆206的固定。由于采用分体式设计，该后盖结构简单，制造方便，成品率高。该后盖集多种功能于一体。
本发明还提供一种扬声器，参照图5，该扬声器包括：上盖4、中盖3、后盖以及磁路系统。后盖安装到中盖3的一侧，上盖4安装到中盖3的与后盖相对的另一侧。上盖4、中盖3和后盖相连接，内部形成容纳腔。容纳腔内安装有磁路组件5。该扬声器的后盖设有连接组件2，扬声器的内部线路通过触点201与外部线路实现电性连接。设有该扬声器的待安装设备的线缆206通过连接组件2的限位装置204进行限位。该扬声器通过连接孔202安装到待安装设备上。该扬声器具有集成度高，安装方便，适用广泛的特点。
虽然已经通过例子对本发明的一些特定实施例进行了详细说明，但是本领域的技术人员应该理解，以上例子仅是为了进行说明，而不是为了限制本发明的范围。本领域的技术人员应该理解，可在不脱离本发明的范围和精神的情况下，对以上实施例进行修改。本发明的范围由所附权利要求来限定。
