背景技术
随着社会经济发展与消费升级，消费者对电子设备例如手机音频性能指标有了更高的要求，这就需要更多的手机空间用于音腔设计，但互相矛盾的是，客户端同时还要求手机应尽量轻薄，提高持握手感，便于携带，因此音腔空间扩容受到限制，甚至需要压缩。
为了扩大音腔体积，一般会在音腔内灌装吸音颗粒，在不扩大音腔物理体积的情况下，提高了音频后腔的等效体积。但目前来看，该技术主要存在如下问题：对于后装隔离板的结构方式，其只能做“平面”设计，而对于拐角区域，需要分别放置两个不同的隔离板和网布，并将两个网布或者将两个隔离板拼接，避免两者之间出现安装间隙；并且对于不同的拐角区域，两个隔离板的拼接方式不同，使得制作复杂，模具及物料成本高，对性能提升、成本控制、产品交付等方面均产生了一定的不利影响。

本发明提出一种透气隔离组件，用于扬声器模组。
具体的，请结合参考图1至图6，扬声器模组包括外壳10、扬声器单体30、及透气隔离组件20，外壳10具有收容腔(图未标)，扬声器单体30收容于该收容腔内，并将该收容腔隔离成前声腔101和后声腔102；透气隔离组件20设置于后声腔102，并与外壳10组配以在后声腔102隔离出第一后腔1021和第二后腔1022，第一后腔1021内填充有吸音材料。如此，通过设置第一后腔1021，并在第一后腔1021内填充吸音材料，以提高扬声器模组的声学性能。
其中，透气隔离组件20为通气阻物部件，可允许气流通过，但阻止吸音材料通过。吸音材料可设置为吸音颗粒，比如沸石颗粒、活性炭等。
在本发明一实施例中，如图-所示，透气隔离组件20包括至少两个隔离件，每一隔离件均包括隔离框21和透气件22，隔离框21具有通气口211，透气件22与隔离框21固定，并且透气件22盖设通气口211。具体的，透气隔离组件20为通气阻物部件，可允许气流通过，但能阻止吸音材料通过；其中，透气件22主要起通气阻物的作用。
一实施例中，在隔离框21和透气件22之间设有胶层，隔离框21与透气件22通过 胶层连接。进一步地，胶层设置为双面胶。如此，不仅可保证透气件22与隔离框21之间的连接强度，还可简化透气件22与隔离框21的装配。当然，胶层也可设置为其它胶，以使透气件22与隔离框21粘接。本实施例中，透气件22与隔离框21采用双面胶或热固胶粘合，制作工艺简单，自动化程度高，因此成本较低。
一实施例中，隔离框21与透气件22注塑结合，即将透气件22作为嵌件而与隔离框21一体注塑，如此能够免去后续安装步骤，避免隔离框21与透气件22之间安装间隙的产生。
本发明实施例中，隔离框21通过冲压或激光切割等工艺方式成型，隔离框21的材质为聚对苯二甲酸乙二醇酯(PET)、聚酰亚胺(PI)、FR4树脂等其中的任意一种。需要说明的是，本发明不限于此，于其它实施例中，隔离框21也可由其材料制成。
本发明实施例中，透气件22既可为网布例如无纺布、尼龙编织网或金属网等其中的任意一种，也可为滤纸、杜邦纸、淋膜纸、网纹纸等其中的任意一种；但不限于此，只要为透气材质制成或为透气形式即可，即可实现通气阻物的目的即可。
一实施中，每一隔离框21上设有多个通气口211，多个通气口211在隔离框21的长度方向上间隔分布。可以理解，通过将通气口211设置有多个，相邻的通气口211之间就会形成有加强筋，如此可提高隔离框21的结构强度，从而可提高透气隔离组件20的结构强度，进而有利于提高透气隔离组件20在扬声器模组外壳10内的稳定性，有利于提高扬声器模组的性能。当然，也可以只设置一个通气口211。比如，当隔离框21尺寸较小时，通气口211的数量可选地设置为一个。
本发明实施例中，相邻两隔离件之间通过连接部221连接，连接部221为弹性件或软质件，以使得两隔离件之间能够相对转动，而改变两隔离件之间的夹角。具体而言，弹性件可为硅胶、橡胶或者是金属片等具有弹性的材质，软质件可为硅胶、橡胶、布或纸等较为柔软的能够产生变形的材质。具体地，连接部221可采用与透气件22相同的材质，例如连接部221采用网布例如无纺布、尼龙编织网、金属网等，或者滤纸、杜邦纸、淋膜纸或网纹纸。
本发明中，通过将两个或者多个隔离件采用连接部221连接起来，并且该连接部221能够产生变形，使得相邻的两个隔离件能够相对转动，而改变两者之间的夹角，即使得该透气隔离组件20实现折弯，在安装到扬声器模组内对应第一后腔1021的拐角位置时，根据拐角处的具体情况来将透气隔离组件20折弯到合适的角度，满足拐角处的安装，而不需要针对不同的拐角来生产不同的透气隔离组件20，故而能够解决其拐角区域设置透气隔离组件 20时拼接复杂的问题，且也有使得制作更加简单，模具及物料成本较低，对性能提升、成本控制、产品交付等方面均产生了一定有利的影响。
一实施例中，相邻两隔离框21间隔设置，相邻两隔离件上的透气件22相互连接而呈一体设置，并且透气件22的位于两隔离框21的间隔处的部分构成连接部221。该实施例中，相当于多个隔离框21上仅需要设置一块大的透气件22即可，多个隔离框21通过透气件22实现连接，不需要再额外设置其它的连接结构，故而能够简化整体结构。在针对不同数量的拐角情况时，也仅需要延长透气件22的长度以及增加隔离框21的数量即可，因此制作流程更加简单。并且采用透气件22形成连接部221的形式，由于透气件22本身是透气阻物的功能，故而能够避免两个隔离框21之间由于装配间隙的存在而导致吸音颗粒通过的现象。再者，连接部221采用透气件22的形式，还能够增加第一后腔1021和第二后腔1022之间的连通面积，即除了通气口211之外，还额外通过连接部221进行通气，因此能够保证第一后腔1021和第二后腔1022之间的气流通畅。另外，将两个隔离框21间隔设置的目的是为了实现形成折弯间隙，以实现折弯功能。
一实施例中，连接部221还可以为单独安装在两个隔离框21上的网布，该网布与透气件22为两个单独的部件。或者，一实施例中，连接部221还可以为单独安装在两个隔离框21上的金属片。
本发明还提出一种扬声器模组。扬声器模组包括：
外壳10，具有收容腔；
扬声器单体30，扬声器单体30收容于收容腔，并将收容腔隔离成前声腔101和后声腔102；以及
透气隔离组件20，透气隔离组件20设置于后声腔102，并与外壳10组配以在后声腔102隔离出第一后腔1021和第二后腔1022，第一后腔1021用于填充吸音材料。
具体的，透气隔离组件20具体结构参照上述实施例，由于本发明扬声器模组采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
其中，扬声器单体30包括振动系统(图未示)和磁路系统(图未示)；其中，振动系统包括振膜和音圈。
通常地，外壳10内设置有限位结构，透气隔离组件20固定装设于该限位结构以防止透气隔离组件20晃动。具体的，限位结构的结构形式有很多，只要能够固定透气隔离组 件20即可，比如，限位结构可以设置为设于外壳10的内壁上的限位槽；又比如，限位结构还可以设置为凸设于外壳10的内壁上的限位凸壁，透气隔离组件20通过双面胶粘接在该限位凸壁上；等等。在本发明的示例中，限位结构设置为插槽，装配时，透气隔离组件20插接于插槽内。
本实施例中，外壳10的内壁上成形有插槽，透气隔离组件20插接于插槽。如此，在装配透气隔离组件20时，只需要将透气隔离组件20从插槽的槽口处插入插槽即可，从而使得透气隔离组件20的装配变得简单、方便，且牢固、稳定。
具体地，插槽包括两个端插槽115和至少一个中间插槽；透气隔离组件20的两端部插接于端插槽115；透气隔离组件20的相邻两隔离件之间呈夹角设计，两隔离件的与连接部221连接的边缘和连接部221形成拐角部分，拐角部分插接于中间插槽。本实施例中，通过设置端插槽115能够对透气隔离组件20的端部进行限位，防止透气隔离组件20的两端部移动。而通过设置中间插槽，能够对拐角部分进行限位，保持透气隔离组件20的相邻两隔离件之间的夹角不变，即防止连接部221变形。
具体地，外壳10具有相对设置的两第一侧壁112，第一侧壁112上凸设有间隔设置的两第一挡壁113，两第一挡壁113之间形成端插槽115，透气隔离组件20具有沿两隔离件的排布方向分布(即沿透气隔离组件20的长度方向分布)的两端部，两端部一一对应插接于两端插槽115。如此，通过固定透气隔离组件20的端部即可固定透气隔离组件20；而且，以上设置结构简单、制作方便。
具体的，两第一侧壁112上均设置有端插槽115，透气隔离组件20的两端部分别插接于两端插槽115内。如此，可使得透气隔离组件20固定的牢固、稳定。
在具体实施例中，第一侧壁112的结构形式有很多，本发明对此不作限定。
一实施例中，中间插槽包括第一中间插槽123，外壳10还具有相对设置的底壁121和顶壁111，底壁121上凸设有间隔设置的两第二挡壁122，两第二挡壁122之间形成第一中间插槽123，拐角部分的底部插接于第一中间插槽123；和/或，中间插槽包括第二中间插槽116，顶壁111上凸设有间隔设置的两第三挡壁114，两第三挡壁114之间形成第二中间插槽116，拐角部分的顶部插接于第二中间插槽116。
上述中，和/或的意思是，在一实施例中，底壁121上设有第一中间插槽123，顶壁111上设有第二中间插槽116。一实施例中，底壁121上设有第一中间插槽123，或者，顶壁111上设有第二中间插槽116。
本发明实施例中，通过设置第一中间插槽123和第二中间插槽116能够分别对拐角部 分的顶部和底部进行限位，即将透气隔离组件20的弯折处进行固定，防止透气隔离组件20继续弯折；而将第一中间插槽123和第二中间插槽116对应拐角部分设置，即相当于对透气隔离组件20的容易变形的位置进行了固定，能够起到更好的防变形的效果。另外，第一中间插槽123和第二中间插槽116仅是对拐角部分的上下两端进行固定，即仅遮挡拐角部分的较小的位置，而拐角部分的较大的区域仍然能够进行透气，故而可大大减小对透气的影响。
一实施例中，第二挡壁122呈弯折状而具有一弯折部；第三挡壁114呈弯折状而具有一弯折部。本实施例中，由于透气隔离组件20是通过连接部221弯折连接的，故而通过将第二挡壁122设置为弯折状，使得第二挡壁122与透气隔离组件20的配合度更好，即第二挡壁122能够沿着相邻两个隔离件之间的拐角部分延伸，同时对相邻两个隔离件以及连接部221进行限位，因此限位效果更好。同理，通过将第三挡壁114设置为弯折状，使得第三挡壁114与透气隔离组件20的配合度更好，即第三挡壁114能够沿着相邻两个隔离件之间的拐角部分延伸，同时对相邻两个隔离件以及连接部221进行限位，因此限位效果更好。可选地，第二挡壁122和第三挡壁114均呈L形设置，如此使得透气隔离组件20弯折形成L状，且两个隔离件之间的夹角为90°。
为方便透气隔离组件20插入插槽，插槽的槽口在透气隔离组件20的插入方向上呈导向缩口设置。具体的，插槽具有相对设置的两内壁面，插槽的槽口呈导向缩口设置指的是，在透气隔离组件20的插入方向上，至少一插槽内壁面在靠近插槽的槽口处向另一插槽内壁面倾斜延伸设置。如此，在装配透气隔离组件20时，导向缩口会对透气隔离组件20起导向作用，从而可便于安装透气隔离组件20的对位与安装。
具体的，端插槽115的槽口在透气隔离组件20的插入方向上呈导向缩口设置，第一中间插槽123的槽口在透气隔离组件20的插入方向上呈导向缩口设置；第二中间插槽116的槽口在透气隔离组件20的插入方向上呈导向缩口设置。如此，当透气隔离组件20插入端插槽115时，可对透气隔离组件20起导向作用；当透气隔离组件20插入第一中间插槽123时，可对透气隔离组件20起导向作用；当透气隔离组件20插入第二中间插槽116时，可对透气隔离组件20起导向作用。
具体的，在透气隔离组件20的插入方向上，至少一第一挡壁113在靠近端插槽115的槽口处具有向另一第一挡壁113倾斜延伸的第一导向面(图未示)，而使得端插槽115的槽口呈缩口。其中，第一导向面可以设置为斜面、或弧面、或曲面、或多段斜面等。
具体的，在透气隔离组件20的插入方向上，至少一第二挡壁122在靠近第一中间插 槽123的槽口处具有向另一第二挡壁122倾斜延伸的第二导向面，而使得第一中间插槽123的槽口呈缩口。其中，第二导向面可以设置为斜面、或弧面、或曲面、或多段斜面等。
具体的，在透气隔离组件20的插入方向上，至少一第三挡壁114在靠近第二中间插槽116的槽口处具有向另一第三挡壁114倾斜延伸的第三导向面，而使得第二中间插槽116的槽口呈缩口。其中，第三导向面可以设置为斜面、或弧面、或曲面、或多段斜面等。
可选地，透气隔离组件20与插槽紧配插合，从而实现更好的密封，阻止吸音颗粒从透气隔离组件20与外壳10的连接缝隙通过。另外，透气隔离组件20与外壳10的内表面也可粘接固定，避免连接缝隙的产生。
具体而言，外壳10包括上壳11和下壳12，上壳11和下壳12围合形成收容腔，扬声器单体30与上壳11共同围成前声腔101，扬声器单体30、下壳12和上壳11共同围合形成后声腔102。可选地，扬声器单体30与上壳11之间粘接固定。
本实施例中，上壳11呈朝下壳12敞口的空腔状，下壳12可呈板状或者是朝上壳11敞口的空腔状。具体地，外壳10包括上壳11和下壳12，上壳11和下壳12围合形成收容腔，扬声器单体30与上壳11共同围成前声腔101，扬声器单体30、下壳12和上壳11共同围合形成后声腔102。上壳11包括顶壁111和第一围壁，第一围壁围设于顶壁111的周缘。下壳12包括底壁121和第二围壁，第二围壁围设于底壁121的周缘，第一围壁和第二围壁相互连接而共同构成外壳10的周壁，周壁包括第一侧壁112。
本实施例中，端插槽115是沿着上下方向延伸从第一围壁延伸至第二围壁的，即端插槽115分别接触底壁121和顶壁111，使得透气隔离组件20的整个端部均为端插槽115包裹，避免缝隙的产生。在其它实施例中，端插槽115也可仅位于第一围壁上或者是仅位于第二围壁。
需要说明的是，本发明并不限于此，于其它实施例中，外壳10还可以设置为其它结构形式，在此不必一一赘述。
本发明一实施例中，发声装置还包括电路板40(FPCB)，该电路板40是分别与扬声器单体30以及外界电源或者内部电源电性连接的，使得扬声器单体30接通电源实现振膜的振动发声。具体地，电路板40一端靠近扬声器单体30并与扬声器单体30电性连接，另一端在第二后腔1022延伸并穿设第二后腔1022，即该另一端穿出第二后腔1022而与外界电源或者内部电源电性连接。本实施例中，透气隔离组件20弯折设置而避开电路板40。
现有的为了增大第一后腔1021的体积，一般是设置一个隔离件，并且隔离件的延伸 方向是与电路板40的延伸方向交叉的，故而为了避免两者干涉，隔离件的高度较低，电路板40从隔离件的上端伸出，即电路板40是伸入到第一后腔1021内后再伸出收容腔的，这就导致第一后腔1021没有被充分利用。另外一种结构中，隔离件沿着电路板40的延伸方向延伸，而为了形成第一后腔1021，故而需要在靠近扬声器单体30的位置设置一堵挡墙，该挡墙的延伸方向与电路板40的延伸方向交叉或是垂直，隔离件一端安装在挡墙上，另一端与收容腔的腔壁连接。然而挡墙的设置占用较多的后腔的空间，导致用于填充吸音材料的第一后腔1021的空间减小。
为解决上述问题，本发明实施例中，通过将透气隔离组件20设置为可弯折形状，其中一个隔离件能够沿着电路板40的长度方向延伸，而避开电路板40，防止电路板40伸入到第一后腔1021内而占用第一后腔1021的空间；另外一个隔离件则靠近扬声器单体30设置，替换原有的挡墙，由于隔离件一般较薄，故可减小对整体空间的占用，能够最大化利用后声腔102的空间；并且由于隔离件替换原有挡墙后，隔离件具有透气功能，因此增大了第一后腔1021和第二后腔1022之间的透气区域，保证了第一后腔1021和第二后腔1022之间的气流通畅。再者，可弯折的透气隔离组件20中部可折弯的结构设计及布局灵活多变，如可适当增加折弯区域，可实现两段及多段折弯，对模组腔体内复杂结构具有较强的适应性。
以上仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是在本发明的发明构思下，利用本发明说明书及附图内容所作的等效结构变换，或直接/间接运用在其它相关的技术领域均包括在本发明的专利保护范围内。
