通过以下参照附图对本发明的示例性实施例的详细描述，本发明的其它特征及其优点将会变得清楚。

具体实施方式
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。
参照图1、图2和图3，本发明公开了一种用于发声装置的音圈，包括：
音圈本体和补强部，所述音圈本体包括音圈骨架1和缠绕在所述音圈骨架1外侧的音圈线5，所述补强部包括第一补强部2和第二补强部3，所述第一补强部2设置于所述音圈骨架1的内侧，所述第二补强部3设置于所述音圈骨架1的外侧；
所述补强部被配置为增强所述音圈的高频强度。
现有技术中的音圈骨架通常采用单层铝镁合金或聚酰亚胺薄膜制成，并在音圈外部增加一层补强纸等结构来提高音圈的强度，但该结构的音圈骨架强度较差，进而影响扬声器的高频声学性能。本发明通过在所述音圈骨架1的内侧和外侧同时设置补强部，防止了所述音圈骨架1由于一侧强度较低而发生朝向所述强度较弱一侧的变形；而且可以通过对补强部的材料、厚度尺寸和设置位置的进一步限定，达到对所述音圈高频强度的提升，抑制高频时所述音圈产生的分割振动，最终应用到发声装置中，所述发声装置可以是扬声器，通过内外补强部补强后的所述音圈可以减少所述发声装置的声音失真，提高所述发声装置的高频声学性能。
传统的发声装置的高频工作范围一般不会超过20KHz，而设置本发明所述音圈的发声装置高频工作范围可以达到40KHz，大大增加了所述发声装置的高频延展性。
可选地，参见图6，所述第一补强部2沿所述音圈骨架1轴向的宽度为h 1，所述第二补强部3沿所述音圈骨架1轴向的宽度为h 2，所述h 1为所述音圈骨架1轴向宽度的5％-30％。
所述音圈骨架1为环形设置，所以在其轴向方向有较长的延伸，所述音圈骨架1在高强度和高频率的振动过程中会受到很大的振动冲击。但由于所述音圈骨架1与所述发声装置的连接部位一般位于所述音圈骨架1的上部，所以所述音圈骨架1的上部受到的振动冲击最大，集中在所述音圈骨架1上部的应力也就越多，所述音圈骨架1的上部成为了主要的受损区域，所以本发明在所述音圈骨架1的上部内侧设置宽度h 1为所述音圈骨架1轴向宽度的5％-30％的所述第一补强部2，便可以有针对性的提高所述音圈骨架1上部易损区域的强度，达到对所述音圈骨架1上部内侧的保护。
同样的，所述h 2可以为所述音圈骨架1轴向宽度的5％-30％。在所述 音圈骨架1的外侧，同样是上部的连接区域最容易受到损坏，所以本发明在所述音圈骨架1的上部外侧设置宽度h 2为所述音圈骨架1轴向宽度的5％-30％的所述第二补强部3，便可以有针对性的提高所述音圈骨架1上部易损区域的强度，达到对所述音圈骨架1上部外侧的保护。
可选地，所述第一补强部2和所述第二补强部3中的至少一个的上端与所述音圈骨架1的上端平齐。
可以理解为，在一种具体的实施方式中，所述第一补强部2的上端与所述音圈骨架1的上端平齐，这样就可以保证所述音圈骨架1的上端内侧从最上端的结构强度就得到增强，而且一直向下延伸到所述第一补强部2设置的整个范围内，这样就更加增强了所述音圈骨架1与所述发声装置连接部位的牢固性和可靠性；在另一种具体的实施方式中，可以是所述第二补强部3的上端与所述音圈骨架1的上端平齐，这样就可以保证所述音圈骨架1的上端外侧从最上端的结构强度就得到增强，而且一直向下延伸到所述第二补强部3设置的整个范围内，这样就同样增强了所述音圈骨架1与所述发声装置连接部位的牢固性和可靠性。
在又一种具体的实施方式中，参见图4，所述第一补强部2的上端和所述第二补强部3的上端均与所述音圈骨架1的上端平齐，这样就进一步保证所述音圈骨架1的上端两侧从最上端的结构强度就得到增强，而且一直向下延伸到所述补强部设置的整个范围内，而且两侧补强不会造成所述音圈骨架1朝向强度较弱一侧的弯曲变形，这样就更加增强了所述音圈骨架1上段的强度，保证了所述音圈骨架1与所述发声装置连接部位的强度和连接寿命。
可选地，参见图5，所述第一补强部2和所述第二补强部3的上端均低于所述音圈骨架1的上端。
由于所述音圈为所述发声装置的重要组件，所述音圈骨架1可能需要与其他部件进行粘接，而粘接其他部件本身就起到了增强所述音圈骨架1结构强度的作用，所以在所述音圈骨架1的上端需要留出粘接空间，这就需要将所述第一补强部2和所述第二补强部3的上端均设置为低于所述音圈骨架1的上端。
可选地，参见图6，所述h 1与所述h 2相等，也就是所述第一补强部2沿所述音圈骨架1轴向的宽度与所述第二补强部3沿所述音圈骨架1轴向的宽度相等，这样设置的好处是平衡所述音圈骨架1内外侧的补强作用，防止所述音圈骨架1向补强较弱的一侧发生弯曲变形。
可选地，参见图4和图5，所述第一补强部2和所述第二补强部3对称设置在所述音圈骨架1的两侧。
在所述第一补强部2沿所述音圈骨架1轴向的宽度与所述第二补强部3沿所述音圈骨架1轴向的宽度相等的基础上，将所述第一补强部2和所述第二补强部3对称设置在所述音圈骨架1的两侧就进一步平衡了所述音圈骨架1内外侧的强度，给所述音圈骨架1补强阶段的强度提供了保证，提高了所述音圈的高频强度。
可选地，参见图6，所述第一补强部2和所述第二补强部3沿所述音圈骨架1轴向的高度差为h 3，所述h 3为所述h 1的5％-80％。
所述第一补强部2和所述第二补强部3沿所述音圈骨架1轴向设置高度差可以提高所述音圈骨架1轴向的补强宽度，例如所述h 3为所述h 1的50％时，也就是所述第一补强部2和所述第二补强部3重叠补强的部分为所述第一补强部2的一半，也就是说所述音圈骨架1轴向的整体补强宽度为所述第一补强部2的一半和全部的所述第二补强部3，这样就结合了所述第一补强部2和所述第二补强部3的补强宽度，最终达到增加所述音圈骨架1轴向的补强宽度的目的。
但是所述第一补强部2和所述第二补强部3沿所述音圈骨架1轴向设置高度差不宜太小，当所述h 3小于所述h 1的5％时，就达不到增加所述音圈骨架1轴向的补强宽度的目的，而当所述h 3大于所述h 1的80％时，所述第一补强部2和所述第二补强部3的补强效果就相当于独立设置，起不到相互补充补强效果的作用。
可选地，所述补强部的材料为铝镁合金、聚酰亚胺薄膜、玻璃纤维和胶水中的一种或多种组合。具体地，所述第一补强部2和所述第二补强部3的材料可以相同。
不同补强材料的密度、力学强度和连接强度均不同，所以为了保证所 述第一补强部2和所述第二补强部3在所述音圈骨架1的两侧达到相同的补强效果，并使两者的补强作用可以相辅相成，共同起到增强所述音圈强度的作用，需要将所述第一补强部2和所述第二补强部3的材料设置为同一种材料，可以都是铝镁合金材料，或者都选择聚酰亚胺薄膜材料，本发明对此不做限制。
当然，所述第一补强部和所述第二补强部的材料也可以不同，可以通过对所述补强材料的密度、尺寸的选择，使得所述第一补强部2和所述第二补强部3在所述音圈骨架1的两侧达到相同的补强效果。
可选地，参见图2，所述第一补强部2呈环形设置。
由于所述音圈骨架1为环形设置，为了达到对所述音圈骨架1内侧的全面补强作用，可以将所述第一补强部2设置为环形，将所述第一补强部2全面贴合在所述音圈骨架1的内侧。
当然，所述第二补强部3也可以设置成环形，将所述第二补强部3全面贴合在所述音圈骨架1的外侧，达到对所述音圈骨架1外侧的全面补强作用。
可选地，所述音圈骨架1侧壁上设置有多个通孔4，多个所述通孔4沿所述音圈骨架1的周侧均匀设置。
具体地，多个所述通孔4设置于所述音圈骨架1上，所述通孔4的设置可以便于所述音圈与其他组件之间连接，比如定心支片可以通过所述通孔4连接至所述音圈，保证所述音圈的稳定连接和有效振动。
本发明还公开了一种发声装置，所述发声装置包括壳体及位于所述壳体内的振动组件；
所述振动组件包括振膜及与所述振膜连接的所述音圈。
所述发声装置可以为扬声器，包括但不限于低音、中音、高音和全频扬声器。特别是在中高音扬声器和全频扬声器的设置中，设置有两侧补强的所述音圈可以显著提高所述扬声器的高频声学性能，增强所述扬声器的高频延展性。
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。
