Description

扬声器壳体和扬声器单体 技术领域
本实用新型属于微型扬声器技术领域，具体地，本实用新型涉及一种扬声器壳体和一种扬声器单体。
背景技术
微型扬声器是现代消费类电子产品中重要的声学器件，随着电子产品的不断发展，微型扬声器的性能也不断提升。增强扬声器的声音性能往往需要增加磁路系统的尺寸，但是手机、平板电脑等电子产品对微型扬声器的体积大小有所限制。所以，为了增加磁路系统的尺寸，本领域技术人员往往通过减薄外壳的厚度来平衡体积的增长。
但是，上述减薄外壳的技术手段易造成外壳强度下降，导致扬声器的可靠性降低。所以，本领域技术人员进一步采用了将部分华司直接注塑在外壳中的方法，以同时达到增加磁路系统尺寸和保证外壳强度的目的。然而，由于华司的尺寸存在制造公差，所以不可避免的，在一体注塑的过程中，华司与塑料外壳的拼接处会出现塑料毛刺，这些毛刺可能伸到扬声器单体的磁间隙或其它结构处，从而对扬声器的声学性能、装配过程以及结构稳定性造成影响。
综上所述，为了保证微型扬声器的声学性能，有必要避免伸出的塑料毛刺对扬声器单体造成的影响。所以，需要对一体注塑有华司的外壳进行改进。或者，可以采用新的技术方案，防止塑料外壳产生毛刺。
实用新型内容
本实用新型的一个目的是避免伸出的塑料毛刺对扬声器单体造成不良影响。
根据本实用新型的一个方面，提供了一种扬声器壳体，其中包括：
围合的侧壁框，所述侧壁框围合的部分为所述侧壁框的内侧；
华司，所述华司一体注塑在所述侧壁框中并且至少一部分暴露在所述侧壁框的内侧，暴露在所述侧壁框内侧的华司的表面与所述侧壁框的表面之间具有接合缝；
所述接合缝两侧的所述华司和侧壁框的表面上设置有避让凹进。
优选地，所述避让凹进可以设置在朝向所述侧壁框内侧的所述接合缝的两侧。
优选地，所述避让凹进还可以设置在朝向所述侧壁框的上方或下方的所述接合缝的两侧。
可选地，所述接合缝可以位于所述华司的两端。
特别地，所述侧壁框可以呈矩形框结构，更优地，所述扬声器壳体可以包括四支华司，所述华司分别位于所述侧壁框的四边上。
优选地，所述侧壁框可以具有华司部，所述华司部位于所述侧壁框内侧，所述华司注塑在所述华司部中。
进一步地，本实用新型还提供了一种扬声器单体，其中包括：
上述扬声器单体；
设置在所述侧壁框内侧的磁路系统，以及设置在所述扬声器壳体上的振动组件；
所述磁路系统与所述华司之间形成有磁间隙。
本实用新型的一个技术效果在于，所述避让凹进在所述接合缝周围产生凹陷，使所述接合缝向所述侧壁框中凹陷一定距离，防止从所述接合缝处伸出的塑料毛刺对扬声器的声音性能造成影响。
通过以下参照附图对本实用新型的示例性实施例的详细描述，本实用新型的其它特征及其优点将会变得清楚。
附图说明
构成说明书的一部分的附图描述了本实用新型的实施例，并且连同说明书一起用于解释本实用新型的原理。

图2是图1的局部放大图；
图3是本实用新型具体实施例中扬声器壳体的局部俯视图；
图4是本实用新型具体实施例中装有部分磁路系统的扬声器单体的俯视图。
具体实施方式
现在将参照附图来详细描述本实用新型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实用新型的范围。
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，决不作为对本实用新型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和设备可能不作详细讨论，但在适当情况下，所述技术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。
本实用新型提供了一种扬声器壳体，其中包括侧壁框，所述侧壁框围合构成闭合的结构，其围合的部分为所述侧壁框的内侧。所述侧壁框中一体注塑有华司，所述华司至少有一部分暴露在所述侧壁框的内侧。例如，所述华司的下表面和部分侧壁可以注塑在所述侧壁框中，华司另一侧表面和上表面则暴露在所述侧壁框的内侧。暴露在所述侧壁框内侧的华司的表面与所述侧壁框的表面之间存在接合缝，在所述接合缝处，所述侧壁框容易生成向外伸出的塑料毛刺。特别地，本实用新型在所述接合缝两侧的所述华司和/或所述侧壁框的表面上设置有避让凹进，所述避让凹进向所述侧壁框中凹陷一定距离，在接合缝周围形成内凹的台阶结构。所述避让凹进使所述接合缝在一定程度上凹入侧壁框中，与华司和侧壁框的原始位置之 间形成一小段避让距离。避让距离的长度通常大于塑料毛刺伸出的长度，这样，即使有塑料毛刺从接合缝处伸出，也不会伸到华司和侧壁框的原始位置处。华司、侧壁框原始位置处的表面作为装配的接触面以及磁间隙等结构的表面，塑料毛刺不会伸到这些位置，也就不会对装配、扬声器性能造成影响。
具体地，如图1、2所示，在本实用新型的一个具体实施例中，所述侧壁框1围合呈矩形框结构，所述华司2注塑在所述侧壁框1靠内侧的一边。所述华司2朝向侧壁框1内侧的一侧以及上侧均暴露在所述侧壁框1内侧，所述接合缝3从华司2上表面的边缘一直延伸到侧面，部分接合缝3还延伸到了华司2的下表面。特别的，如图2、3所示，所述避让凹进4设置在华司2侧表面的接合缝3周围，所述避让凹进4包括在华司2的侧表面上形成的台阶结构41，并从台阶结构41经接合缝3延伸到侧壁框1上，整个避让凹进4向侧壁框1中凹陷，使接合缝3相对于华司2原始的侧边位置具有一段避让距离。
特别的，在图1-3所示的实施例中，只有华司2上形成有台阶结构41，所述侧壁框1的内表面没有形成台阶结构，也即没有将所述接合缝3周围的侧壁框1内表面恢复到原始位置。在本实用新型的其它实施例中，所述避让凹进的台阶结构可以同时设置在接合缝两侧的华司和侧壁框上，即所述避让凹进形成一个凹槽或者凹坑，将接合缝陷入其中。或者，所述台阶结构只设置在侧壁框上，所述避让凹进从台阶结构经接合缝延伸到华司上。本实用新型并不对避让凹进的台阶结构设置的位置进行限制，本领域技术人员可以根据扬声器壳体的实际情况，将台阶结构设置在华司和/或侧壁框的不同位置。
可选地，在图1-3所示的实施例中，所述避让凹进4设置在朝向所述侧壁框1内侧的接合缝3的两侧，这种避让凹进4可以防止接合缝3处的塑料毛刺伸入到磁间隙中。在本实用新型的其它实施例中，所述避让凹进4还可以设置在其他位置。例如，以图2中的结构为例，所述避让凹进4可以设置在朝向所述侧壁框1的上方或下方的所述接合缝3的两侧，即避让凹进设置在华司2的上表面或下表面，使接合缝向下或向上凹进一段距 离。这样，当有其它扬声器部件安装在华司的上表面或下表面时，装配面不会受到接合缝处的塑料毛刺影响，能够增强扬声器的结构稳定性。
另外，在实际应用中，由于对扬声器的结构、性能有不同的要求，所以所述侧壁框、华司的结构并不统一，所述接合缝出现的位置也不相同。例如，在图1-3所示的实施例中，所述接合缝3出现在所述华司2的两端，接合缝3从华司的上表面经侧面延伸到下表面。但是在其它实施例中，所述接合缝可以只出现在华司的侧面或者上表面。例如，当所述华司的下表面和侧面均嵌入所述侧壁框，仅有上表面暴露在侧壁框内侧时，所述接合缝仅出现在华司2的上表面；当所述华司只有一个侧面从所述侧壁框的内侧暴露出来时，所述接合缝只出现在所述华司的侧面。
可选地，如图1、3所示，所述侧壁框1可以具有四条直边，围合形成矩形框结构，这种结构装配较容易。优选地，当所述侧壁框1呈矩形框结构时，所述扬声器壳体可以包括有四支华司2，四支华司2分别设置在侧壁框1的四条边上。当然，本领域技术人员也可以根据实际情况，对所述侧壁框的为何形状进行修改，例如使用椭圆形侧壁框；另外，也可以在侧壁框上设置不同数量的华司，例如三支或五支华司，本实用新型不对此进行限制。
特别地，如图1、2所示，所述侧壁框1可以具有华司部11，所述华司部11通常位于所述侧壁框1的内侧，对所述华司2起承载作用，所述华司2设置在所述华司部11中。在扬声器单体结构中，往往需要在华司2的上、下表面设置其它部件，所述华司部11能够对华司2起到良好的支撑作用，并且使华司2向侧壁框的内侧伸出一部分，便于在其上、下表面设置零部件。
进一步地，本实用新型还提供了一种扬声器单体，其中包括上述扬声器壳体。在所述扬声器壳体上设置有振动组件，在所述侧壁框1的内侧设置有磁路系统。图4为装有部分磁路系统的扬声器壳体俯视图，如图4所示，所述磁路系统与所述华司2之间形成有磁间隙。所述避让凹进4可以使所述接合缝3向远离所述磁间隙的方向凹进一小段距离，从而防止塑料毛刺伸入到所述磁间隙中。由于振动组件的音圈位于所述磁间隙中，如果 塑料毛刺伸入所述磁间隙，会对音圈的振动产生影响。在图4示出的实施例中，本扬声器壳体能够避免塑料毛刺对扬声器单体的声音性能造成影响。在本实用新型的其它实施例中，当所述避让凹进设置华司的上表面或下表面时，本扬声器壳体还可以避免塑料毛刺对磁路系统的安装稳定性造成影响。
虽然已经通过示例对本实用新型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，以上示例仅是为了进行说明，而不是为了限制本实用新型的范围。本领域的技术人员应该理解，可在不脱离本实用新型的范围和精神的情况下，对以上实施例进行修改。本实用新型的范围由所附权利要求来限定。
