Description

扬声器模组 技术领域
本发明涉及电声技术领域。更具体地，涉及一种扬声器模组。
背景技术
扬声器模组通常会在模组外壳上开设出声孔，振膜发出的声音通过出声孔向外界传播。为了保证扬声器模组与整机装配后的密封性，一般会在出声孔的四周粘贴密封圈，密封圈的材料大都是硅橡胶。但在密封圈的粘贴过程中，不易对密封圈进行定位，密封圈容易贴偏，会遮挡住一部分出声孔，从而导致整机的一致性较差，影响整机的声学效果且密封不良。
目前有一种扬声器模组通过二次成型的方式，将硅橡胶注塑到模组壳体的出声孔上形成密封圈，但此种方法就得需要模组壳体的塑胶材料要耐高温，一般会选择PEI材料，PEI材料相对于普通模组外壳的材料，如D151、D251等要高很多，从而会提高模组外壳的成本。并且扬声器模组外壳都是结构复杂的注塑件，采用二次注塑的二射模具也将会变得结构复杂，一方面会整体提高扬声器模组的制作成本，另一方面二射之后的模组外壳的整体尺寸也不易保证。因此，发明人提出一种技术方案，在扬声器模组中增加一个环形的分离声孔，密封圈通过二次注塑的方式与分离声孔一体形成，分离声孔环绕出声孔设置，并通过胶水与模组壳体粘接固定。
但是此种结构的扬声器模组在跌落可靠性测试时，分离声孔与模组外壳的结合强度不足以克服跌落冲击时的弯矩，分离声孔会从模组外壳上脱落，从而使可靠性测试失败。
发明内容
本发明的目的在于提供一种分离声孔难以从模组壳体上脱落、可靠性高的扬声器模组。
根据本发明的一个方面，提供了一种扬声器模组，包括形成容纳空间的模组壳体，以及设置在所述容纳空间中的扬声器单体，所述扬声器单体将所述容纳空间分隔为前声腔和后声腔，所述模组壳体开设有与前声腔连通的出声孔，靠近所述出声孔处的模组壳体外侧表面固定结合有固定部，该扬声器模组还 包括环形的分离声孔，所述分离声孔靠近模组壳体的一侧表面向外凸起形成插接部，所述插接部具有与所述出声孔的内侧表面匹配对应的外形，所述插接部与出声孔设置为过盈配合，且所述分离声孔通过软韧性粘接剂粘接于所述固定部的表面。
优选地，所述固定部由所述模组壳体的外侧表面向外凸起形成，所述固定部的截面形状为U型。
优选地，所述分离声孔的外形为矩形，与所述U型固定部匹配对应，所述软韧性粘接剂包括沿所述U型固定部的两内侧棱边分别延伸的条型的第一胶条，所述第一胶条位于分离声孔的底面外侧边缘与U型固定部的两内侧棱边之间。
优选地，所述分离声孔的底面外侧边缘向内凹陷形成第一容胶槽，所述第一胶条的一侧位于所述第一容胶槽内。
优选地，所述软韧性粘接剂还包括沿所述U型固定部顶面内侧边缘延伸的U型第二胶条，所述第二胶条位于所述分离声孔的外侧表面与U型固定部顶面内侧边缘之间。
优选地，所述U型固定部顶面内侧边缘向内凹陷形成第二容胶槽，所述第二胶条的一侧位于所述第二容胶槽内。
优选地，所述出声孔的截面形状为矩形，所述分离声孔插接部的截面形状为U型。
优选地，所述U型插接部为倒U型设置，且U型的开口与所述分离声孔的底面齐平。
优选地，所述插接部的两侧壁均位于所述分离声孔侧壁边缘的内侧。
优选地，所述插接部的宽度小于或等于所述模组壳体上出声孔的宽度。
本发明的有益效果如下：
本发明扬声器模组的分离声孔插接部设置为与壳体出声孔过盈配合，同时分离声孔还通过软韧性粘接剂与壳体上突出的固定部粘接固定，使得跌落测试时，分离声孔产生的弯折力由壳体承担，减少分离声孔与固定部之间产生分离力，同时，由软韧性粘接剂提供缓冲吸能、吸收振动冲击，从而不易在分离声孔与壳体之间产生裂缝，造成分离声孔从壳体上脱落，提高了本扬声器模组的可靠性。
附图说明
下面结合附图对本发明的具体实施方式作进一步详细的说明。
图1示出本发明的分解结构示意图。
具体实施方式
为了更清楚地说明本发明，下面结合优选实施例和附图对本发明做进一步的说明。附图中相似的部件以相同的附图标记进行表示。本领域技术人员应当理解，下面所具体描述的内容是说明性的而非限制性的，不应以此限制本发明的保护范围。
如图1所示，本实用新型提供了一种扬声器模组，该模组包括模组壳体和扬声器单体，模组壳体中形成有容纳空间，扬声器单体收容于该容纳空间中，并将该容纳空间分隔成前声腔和后声腔。扬声器单体为动圈式单体或者动铁式单体。为了便于说明，在本实施例中以动圈式单体为例。动圈式单体包括振动组件和磁路组件。振动组件包括振膜和音圈，振膜与音圈固定连接。所述磁路系统包括磁轭以及设置于所述磁轭一侧表面上的中心磁铁和边磁铁，中心磁铁和边磁铁之间形成磁间隙，音圈的一端插入磁间隙中。当音圈通电后，音圈会在磁路系统的作用下振动，与此同时，音圈驱动振膜一同振动，实现振膜的发声。模组壳体包括相互配合的上壳1和中壳2，中壳2的侧壁上开设有出声孔，出声孔与前声腔连通，振膜发出的声音通过出声孔向外界传播。这属于本领域技术人员的公知常识，在此不再具体说明。
本发明的扬声器模组还包括分离声孔3，分离声孔3设置为环形，其靠近中壳2一侧的表面向外凸起形成插接部31，插接部31的形状与出声孔的内侧表面匹配对应，插接部31与出声孔设置为过盈配合。分离声孔3的侧壁设有与出声孔连通的开口，出声孔以及分离声孔3的侧壁围合形成的空间共同形成出音通道，振膜发出的声音通过该出音通道向外界传播。
中壳2靠近出声孔的外侧表面固定结合有固定部22，分离声孔3的插接部31插入出声孔后，分离声孔3通过软韧性粘接剂粘接于固定部22表面。软韧性粘接剂可以是硅胶，所述硅胶固化后具有一定的弹性。
插接部31可以位于分离声孔3的侧面使分离声孔3横向插入中壳2的出声孔中，插接部31也可以位于分离声孔3的端面使分离声孔3纵向插入中壳2的出声孔中。如图1所示的本实施方式中，插接部31位于分离声孔的侧面，当进行跌落可靠性测试时，由于插接部31与出声孔紧密配合，使得分离声孔 3受到的弯折力由中壳2承担，增强了分离声孔3与中壳2的结合强度，同时软韧性粘接剂能够吸收冲击振动，减少分离声孔3与固定部21之间产生裂缝的情况发生，使得分离声孔3难以从中壳2上脱落，提高了本发明扬声器模组的可靠性。
进一步地，如图1所示的本实施方式的固定部22由中壳2的外侧表面凸起形成，固定部22位于出声孔的下方，分离声孔3横向与中壳2插接后，再利用软韧性粘接剂将分离声孔3粘接于固定部22的表面。固定部22的形状与分离声孔3的外形相对应，本实施方式中固定部22设置为U形，分离声孔3的外形设置为与U型固定部对应的矩形。具体地，分离声孔3的底面粘接于U型固定部22内侧表面，软韧性粘接剂沿U型固定部的两内侧棱边延伸，分别形成两条第一胶条4，第一胶条4粘接在U型固定部的两内侧棱边与分离声孔3的两侧边缘之间。分离声孔3通过第一胶条4与固定部22粘接固定，由于第一胶条4为软韧性材料，具有一定的弹性，因此第一胶条4可吸收振动冲击，在跌落时可防止分离声孔3与固定部22之间出现裂缝，一方面保证了出音通道的密封性能，另一方面提高了本扬声器模组的可靠性。
进一步地，本实施方式中分离声孔3的底面外侧边缘向内凹陷形成第一容胶槽32，第一胶条4的一侧位于第一容胶槽32内与分离声孔3粘接。此种结构可防止溢胶现象发生，提高产品的美观程度。
为了提高分离声孔3与U型固定部22之间的粘接牢固度，提高胶条吸收振动冲击的能力，本实施方式进一步地包括有第二胶条5，第二胶条5沿固定部22顶面内侧边缘延伸形成U型。第二胶条5粘接在固定部顶面内侧边缘与分离声孔3的外侧表面之间，分离声孔3的上部通过第二胶条5与固定部22粘接固定，分离声孔3的底部通过第一胶条4与固定部22粘接固定。分离声孔3的上部与下部通过多个胶条与固定部22粘接固定，进一步提高对振动冲击的吸收，能够提供更良好的减震吸能效果。
进一步地，固定部22顶面内侧边缘向内凹陷形成第二容胶槽23，第二胶条5的一侧位于位于第二容胶槽23内，此种结构可防止溢胶现象发生，提高产品的美观程度。
在另一实施方式中，固定部22设置为平板状，分离声孔4仅通过位于底面边缘的第一胶条4粘接在平板状固定部22的表面。
进一步地，插接部31需要具有与出声孔对应的形状，插接部31的外侧 表面需要与出声孔的内侧表面紧密贴合，实现二者的过盈配合。本实施方式中出声孔的截面形状为矩形，插接部31的截面形状为U型，U型的插接部外表面与出声孔的三侧内侧表面贴合。在另一实施方式中，出声孔的截面形状为矩形，插接部31的截面形状为矩形。优选地，本实施方式的U型插接部31设置为倒U型，U型插接部31的开口与分离声孔3的底面齐平，插接部31的两侧壁位于分离声孔3边缘的内侧。插接部31的侧壁厚度以能保证插接部与出声孔过盈配合的强度为准，如厚度过大将影响出声孔的截面面积，减小出音通道的截面面积，进而降低扬声器模组的声学效果。由于本实施方式中的插接部31全部插入出声孔内，因此插接部31的宽度，也就是插入出声孔内的深度小于或等于中壳2的侧壁厚度，避免插接部31伸入中壳内部与其它部件产生干涉。
显然，本发明的上述实施例仅仅是为清楚地说明本发明所作的举例，而并非是对本发明的实施方式的限定，对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动，这里无法对所有的实施方式予以穷举，凡是属于本发明的技术方案所引伸出的显而易见的变化或变动仍处于本发明的保护范围之列。
