Description

一种采用热塑性硫化橡胶一体成型的被动喇叭及其制备方法
技术领域
本发明涉及一种喇叭，尤其是涉及一种采用热塑性硫化橡胶一体成型的被动喇叭及其制备方法。
背景技术
目前业界使用的被动喇叭传统制备工艺是：音响的硬胶外壳、折环、铁片等单独加工完成，然后再经过表面处理、涂胶、贴合、压实等等加工工序。
这种多工序加工方式生产效率低，产成品合格率低，折环使用的是热固性橡胶材料热压成型，边角料不能再次使用，造成浪费。表面处理和涂胶工艺的挥发物容易造成环境污染，手工贴合往往造成边界线不平齐，影响产品外观。
发明内容
为了解决现有技术存在的上述问题，本发明提供了一种采用热塑性硫化橡胶一体成型的被动喇叭及其制备方法。
为实现上述目的，本发明提供了如下技术方案：
一种采用热塑性硫化橡胶一体成型的被动喇叭，包括：第一外壳、第二外壳、内壳和铁片；所述第一外壳包括密封圈、折环和振动膜，所述密封圈、折环和振动膜一体注塑成第一外壳；所述第二外壳内设有凹槽，所述第一外壳置于凹槽内；所述振动膜背面设有外壳凹槽，所述外壳凹槽依次嵌入内壳和铁片。
进一步地，所述内壳的剖面为T型结构，所述铁片的剖面为倒T形结构，所述T型结构和倒T形结构相配合。
进一步地，所述铁片上设有2个定位孔。
进一步地，所述定位孔形状为条形孔或圆孔。
本发明还提供了上述采用热塑性硫化橡胶一体成型的被动喇叭的制备方法，具体包括以下步骤：
S1、铁片依靠定位孔在模具中定位；
S2、将熔融的塑胶原料注射到模具中，同时注塑成型第一外壳、第二外壳和内壳包铁片，形成一体结构，其中，第一外壳由密封圈、折环、振动膜一体注塑形成；
S3、注塑完成后，经过运水冷却后顶出脱模。
其中，所述步骤S2中，也可采用包胶的形式，将熔融的塑胶原料注射到模具中，先注塑成型第二外壳、内壳包铁片，再注塑成型第一外壳形成一体结构，其中，第一外壳由密封圈、折环和振动膜一体注塑形成。
进一步地，步骤S2中，所述第一外壳的材质为热塑性硫化橡胶。
进一步地，步骤S2中，所述第二外壳和内壳的材质均为PP和玻纤的复合材料。
进一步地，步骤S3中，所述注塑温度为180-350摄氏度，注塑压力为40-200MPa。
基于上述的技术方案，本发明取得的技术效果为：
（1）本发明提供的采用热塑性硫化橡胶一体成型的被动喇叭，采用一体注塑成型工艺将密封圈、折环和振动膜注塑成一体式结构，注塑过程容易实现、封装稳定，其结构简单，密封效果好，结构牢固，外观完美，没有结合线。
（2）本发明提供的采用热塑性硫化橡胶一体成型的被动喇叭，在一体注塑成型条件下能提高良品率，保证产品质量，节省了装配时间和人力成本，提高生产效率。
