Description

一种扬声器模组壳体、扬声器模组及发声装置 技术领域
本发明涉及声学器件领域，更具体地，本发明涉及一种扬声器模组壳体，具有该扬声器壳体的扬声器模组，及应用了该扬声器模组的发声装置。
背景技术
移动互联时代，消费类电子产品越来越受青睐，大量的智能设备出现在人们的日常生活里。扬声器作为一种发声器件，被广泛应用于消费电子产品中。目前常见的扬声器主要有动圈式扬声器、电磁式扬声器、电容式扬声器、压电式扬声器等，动圈式扬声器因其具有制作相对简单、成本低廉、有较好的低频发声优势等特点，而得以广泛应用。但在设备轻薄化、大功率化的趋势下，留给扬声器的空间越来越小，合理设计扬声器模组，使其既能适应轻薄化手机的要求，又能适应大功率输出下高振动位移的需求变得越来越重要。
为了达到轻薄化设计的目标，通常使用轻薄的金属材质薄片嵌入到扬声器的塑料壳体中，代替原有的全塑料壳体，来达到减小模组厚度的目的，但该设计存在以下缺陷：大面积的金属片导致模组外壳***，受挤压容易变形，影响扬声器装配及振动空间，以及扬声器受热时大面积的金属片产生的形变程度与塑料外壳不同，导致金属片与塑料外壳粘接部分产生失效，容易出现声腔泄露等影响扬声器性能的现象。
发明内容
本发明的一个目的是提供一种扬声器模组壳体，以在减小扬声器模组的厚度的同时，有效地避免壳体变形以及保证扬声器的声学性能。
根据本发明的一个方面，提供一种扬声器模组壳体，包括壳体主体和至少两片与所述壳体主体固定连接的金属片，其中，所述壳体主体包括连 接部，所述连接部将相邻的所述金属片彼此分隔，所述金属片的边缘与所述连接部搭接在一起。
可选地，所述金属片与所述连接部邻近外界的一面搭接在一起。
可选地，所述连接部与所述金属片搭接的部分的厚度小于所述连接部未与所述金属片搭接的部分的厚度。
可选的，所述金属片与所述连接部搭接的部分的厚度小于所述金属片未与所述连接部搭接的部分的厚度。
可选的，所述金属片具有矩形形状。
可选的，各所述金属片之间彼此绝缘。
可选的，所述扬声器模组壳体为一体成型结构。
本发明的另一个目的是提供一种扬声器模组，以保护扬声器的声学性能。
根据本发明的另一个方面，提供一种包括本发明的扬声器模组壳体的扬声器模组。
可选的，所述金属片上设有焊盘结构。
本发明还有一个目的是提供一种发声装置，以方便对发声装置中的扬声器进行定位。
根据本发明的第三方面，提供一种发声装置，包括本发明的扬声器模组，其中，所述金属片与所述连接部搭接的部分的外表面和所述金属片未与所述连接部搭接的部分的外表面不共面，以形成相对于所述金属片未与所述连接部搭接的部分的外表面所在平面的凸起或凹陷，所述发声装置上设有与所述凸起或所述凹陷相配合的结构。
本发明的发明人发现，在现有技术中，确实存在扬声器模组壳体因大面积的金属片导致容易变形，以及大面积金属片与塑料外壳连接易失效导致影响扬声器声学性能的问题。因此，本发明所要实现的技术任务或者所要解决的技术问题是本领域技术人员从未想到的或者没有预期到的，故本发明是一种新的技术方案。
本发明的一个技术效果在于，在扬声器模组壳体中设置有多个通过连接部彼此分隔的金属片，连接部的设置有效加强了对金属片的支撑，以克 服金属片面积过大导致扬声器模组壳体容易变形的缺陷，而且多个金属片受温度影响的变形可被分散，不易因金属片变形过大而与壳体主体连接失效，有效保证了扬声器的声学性能。
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。

壳体主体-1，连接部-11，金属片-2。
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。
本发明为了解决扬声器模组壳体因大面积的金属片导致容易变形，以 及大面积金属片与塑料外壳连接易失效导致影响扬声器声学性能的问题，提供了一种扬声器模组壳体，如图1和图2所示，包括壳体主体1和至少两片与所述壳体主体1固定连接的金属片2，其中，所述壳体主体1包括连接部11，所述连接部11将相邻的所述金属片2彼此分隔，所述金属片2的边缘与所述连接部11搭接在一起，上述固定连接可通过焊接或一体成型等方式实现，上述金属片2的数量和材质可根据实际需求灵活需求，例如，如本发明的具体实施例中金属片2为两片，如有必要，金属片2的数量也可为三片或四片或更多，金属片2的材质可为本领域常用的钢，即金属片2为钢片。本领域技术人员应当清楚，壳体主体1通常为塑料材质，连接部11在相邻金属片2之间起到与金属片2连接以及将相邻金属片2隔开的作用，连接部11与金属片2之间通过搭接的方式连接还更有利于连接部11对金属片2进行支撑。
而且，扬声器模组壳体的典型结构包括采用粘接或超声焊接方式连接在一起的上壳(或上盖)和下壳，金属片2通常设于上壳上，但本领域技术人员可容易想到，金属片2不仅限于设在上壳上，对于扬声器模组壳体的其它塑料材质的部件上也可设有金属片2，例如，扬声器模组壳体的下壳。
本发明在扬声器模组壳体中设置有多个通过连接部11彼此分隔的金属片2，连接部11的设置有效加强了对金属片2的支撑，以克服金属片2面积过大导致扬声器模组壳体容易变形的缺陷，而且多个金属片2受温度影响的变形可被分散，不易因金属片2变形过大而与壳体主体1连接失效，有效保证了扬声器的声学性能。
为了进一步加强连接部11对金属片2的支撑效果，所述金属片2与所述连接部11邻近外界的一面搭接在一起，上述外界是指与扬声器模组壳体远离其内部装设的扬声器零部件的表面相通的空间。
在本发明扬声器模组壳体的一个具体实施例中，所述连接部11与所述金属片2搭接的部分的厚度小于所述连接部11未与所述金属片2搭接的部分的厚度，这种设置有利于避免扬声器模组壳体上的连接部11与金属片2搭接的部分的厚度过厚导致的搭接处的应力集中，从而防止连接部11与金 属片2之间的连接失效，在实际操作中，可对连接部11上的搭接部分进行减薄处理。
在本发明扬声器模组壳体的另一个具体实施例中，所述金属片2与所述连接部11搭接的部分的厚度小于所述金属片2未与所述连接部11搭接的部分的厚度，这种设置有利于避免扬声器模组壳体上的金属片2与连接部11搭接的部分的厚度过厚导致的搭接处的应用集中，从而防止金属片2与连接部11之间的连接失效，在实际操作中，可对金属片2上的搭接部分进行减薄处理。
金属片2的具体形状可根据实际需求设置，在一个具体的实施例中，所述金属片2如图1所示具有矩形形状，本领域技术人员可容易想到，金属片2也可具有圆形或正方形等形状。
为了防止各金属片2的变形相互影响，以及方便在金属片2上设置例如PAD(焊盘)等结构，各所述金属片2之间彼此绝缘，也即是，壳体主体1完整包覆金属片2的边缘。
为了方便扬声器模组壳体的强度，所述扬声器模组壳体为一体成型结构。
如图2所示，本发明还提供了一种扬声器模组，其包括本发明的扬声器模组壳体，扬声器模组的典型结构包括扬声器模组壳体和扬声器单体，其中扬声器模组壳体具有用于收容扬声器单体的腔体，扬声器单体定位在腔体中，扬声器单体的典型结构包括振动***、磁路***及辅助***，上述辅助***包括可收容振动***和磁路***的外壳，上述振动***包括振膜和固定于振膜一侧的振动音圈，振膜包括与外壳固定的固定部、与固定部一体设置的凹或凸结构的折环部及位于折环部内的平面部；上述磁路***包括盆架、固定在盆架上的磁铁和华司。
本发明的扬声器模组的扬声器模组壳体中设置有多个通过连接部11彼此分隔的金属片2，连接部11的设置有效加强了对金属片2的支撑，从而克服金属片2面积过大导致扬声器模组壳体容易变形的缺陷，而且多个金属片2受温度影响的变形可被分散，不易因金属片2变形过大而与壳体主体1连接失效，有效保证了扬声器模组的声学性能。
在本发明扬声器模组的一个具体实施例中，所述金属片2上设有焊盘结构。
本发明还提供了一种发声装置，其包括本发明的扬声器模组，其中，所述金属片2与所述连接部11搭接的部分的外表面和所述金属片2未与所述连接部11搭接的部分的外表面不共面，以形成相对于所述金属片2未与所述连接部11搭接的部分的外表面所在平面的凸起或凹陷，所述发声装置上设有与所述凸起或所述凹陷相配合的结构，本领域技术人员可容易想到，发声装置上与扬声器模组上的凸起相配合的结构为凹陷或凹槽等结构，发声装置上与扬声器模组上的凹陷相配合的结构为凸台或凸出等结构，这种配合结构有利于扬声器模组在发声装置中的定位或固定，从而减小扬声器模组的装配难度，而且，扬声器模组上的凸起或凹陷还有利于将壳体主体1与金属片2之间的搭接处的应力分散减弱，从而更好地防止壳体主体1与金属片2之间的连接失效。
虽然已经通过示例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，以上示例仅是为了进行说明，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。
