Description

喇叭及耳塞式耳机
本申请要求于2017年03月01日提交中国专利局、申请号为201710117347.8、发明名称为“喇叭及耳塞式耳机”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及耳机技术领域，尤其涉及一种喇叭及耳塞式耳机。
背景技术
随着科技的快速发展，人们对生活品质的要求越来越高，消费类电子产品正朝着高品质化方向发展，这种趋势在耳机的研发、生产中尤为明显。像目前的诸多品牌的手机一样，也都在朝着防水功能发展，不仅仅再局限于可实现防水功能的耳机，还希望能够在满足防水功能的前提下，还可以进一步的提升音质效果。
目前具有防水功能的耳机采用如下技术：现有的调音技术，即为喇叭后声腔做泄声孔的设计来扩展低频，泄声孔需要通畅并且具有较高的透气量；但由于IPX7的防水材料透气量均很低，均基本为不透气型，不能达到泄声孔所要求的两个条件：一是通畅、二是要有高的透气量，而致低频效果较差。如果是仅通过增加后声腔的体积的方式来提升低频效果，则会导致产品体积增大，使产品显得笨重，破坏了产品的美观性。封闭的后声腔在喇叭工作过程中，即振膜振动时，振膜会压缩后声腔体积，造成后声腔内部压强增大，而反作用力到振膜，从而使振膜振动力减弱，而导致不能释放出足够强的低音效果。
发明内容
本发明的第一个目的在于提供一种喇叭，能够增强振动性能增强低音效果。
本发明是这样实现的，一种喇叭，所述喇叭包括喇叭支架，所述喇叭支架包括呈筒状的喇叭壳体，在所述喇叭壳体围成腔体内设有沿径向设置的分隔板；在所述分隔板的两侧分别设有第一喇叭、第二喇叭，所述第一 喇叭、所述第二喇叭均包括固定在所述分隔板上的磁路***、以及边缘部固定在对应侧所述喇叭壳体端部的振动***；所述磁路***包括依次固定在所述隔板上的磁铁和华司，所述磁铁和所述华司与所述喇叭壳体之间设有磁间隙，位于所述磁间隙位置的所述分隔板上设有气压平衡孔；所述振动***包括音圈、以及盖设在所述喇叭壳体端部的振膜，所述音圈与所述振膜的侧面固定连接。

作为一种改进，所述气压平衡孔设有多个。
作为一种改进，多个所述气压平衡孔呈环状阵列排列。
由于采用了上述技术方案，本发明的喇叭包括呈筒状的喇叭壳体，在喇叭壳体围成腔体内设有沿径向设置的分隔板；在分隔板的两侧分别设有第一喇叭、第二喇叭，第一喇叭、第二喇叭均包括固定在分隔板上的磁路***、以及边缘部固定在对应侧喇叭壳体端部的振动***；磁路***包括依次固定在隔板上的磁铁和华司，磁铁和华司与喇叭壳体之间设有磁间隙，位于磁间隙位置的分隔板上设有气压平衡孔；振动***包括音圈、以及盖设在喇叭壳体端部的振膜，音圈与振膜的侧面固定连接。工作时分别给第一喇叭的音圈、第二喇叭的音圈通入不同极性的信号电流，电磁感应产生同方向的振动力，使第一喇叭的振膜、第二喇叭的振膜的振动方向相同，增强了振动性能提高了低音效果，提升了声学性能。
本发明的第二个目的在于提供一种防水的耳塞式耳机，旨在解决现有耳塞式耳机低音效果差的问题，能够提高声学性能。
本发明是这样实现的，一种耳塞式耳机，所述耳塞式耳机包括扣合在一起的耳机前壳与耳机后壳，在所述耳机前壳与所述耳机后壳所围的空间内安装有上述喇叭，在所述耳机前壳上设有若干前壳出声孔，在若干所述前壳出声孔与所述喇叭之间设有声学防水膜。
作为一种改进，所述喇叭的第一喇叭或者所述第二喇叭朝向所述耳机前壳设置。
作为一种改进，在所述耳机后壳远离所述耳机前壳的一端处设有耳机出线孔，在所述耳机出线孔上安装有柔性的线卡。
由于采用了上述技术方案，本发明提供的耳塞式耳机包括扣合在一起的耳机前壳与耳机后壳，在耳机前壳与耳机后壳所围的空间内安装有喇叭，在耳机前壳上设有若干前壳出声孔，在若干前壳出声孔与喇叭之间设有声学防水膜。由于在耳机前壳与耳机后壳所围的空间内安装有上述喇叭，该喇叭的第一喇叭的振膜、第二喇叭的振膜的振动方向相同，增强了振动性能提高了低音效果，提升了耳塞式耳机的声学性能，同时由于在若干前壳出声孔与喇叭之间设有声学防水膜，在耳机后壳上没有设置泄声孔，增强了耳塞式耳机的防水性能。

在喇叭壳体的两端部的外侧均设有凸缘，振动***的边缘部固定在凸缘上，具体的说是，振膜的边缘部固定在凸缘上，在凸缘相对的两侧分别设有通孔；在靠近第一喇叭105a一侧的凸缘上对应两侧通孔处分别设有第 一喇叭正极206a、第一喇叭负极207a，第一喇叭正极206a、第一喇叭负极207a分别与音圈203a的两端电连接；在靠近第二喇叭105b一侧的凸缘上对应两侧通孔处分别设有第二喇叭正极206b、第二喇叭负极207b，分别与音圈203b的两端电连接。
工作时，分别给第一喇叭105a的音圈203a、第二喇叭105b的音圈203b通入不同极性的信号电流，电磁感应产生同方向的振动力，使第一喇叭105a的振膜201a、第二喇叭105b的振膜201b的振动方向相同，增强了振动性能提高了低音效果，提升了声学性能。
由图3可知，该耳塞式耳机包括扣合在一起的耳机前壳101a与耳机后壳101b，在耳机前壳101a与耳机后壳101b所围的空间内安装有上述喇叭，喇叭将耳机前壳101a与耳机后壳101b所围的空间分隔为前声腔和后声腔106，在耳机前壳101a上设有若干前壳出声孔104，在若干前壳出声孔104与喇叭之间设有声学防水膜102，声学防水膜102与第一喇叭105a的振膜201a之间围成第一腔室109；该喇叭的第一喇叭105a或者第二喇叭105b朝向耳机前壳101a设置，便于声音的传递，在耳机前壳101a的外侧上安装有耳塞部103，利于将耳塞式耳机安放在耳朵上。
由于在耳机前壳101a与耳机后壳101b所围的空间内安装有上述喇叭，该喇叭的第一喇叭105a的振膜201a、第二喇叭105b的振膜201b振动方向相同，增强了振动性能提高了低音效果，提升了耳塞式耳机的声学性能；同时由于在若干前壳出声孔104与喇叭之间设有声学防水膜102，在耳机后壳101b上没有设置泄声孔，增强了耳塞式耳机的防水性能。
在本实施例中，声学防水膜102的防水等级为IPX7，当然也可以根据具体工作环境选择更高的防水等级，或者低级别的防水等级。
在本实施例中，在耳机后壳101b远离耳机前壳101a的一端处设有耳机出线孔110，在耳机出线孔110上安装有柔性的线卡111，可以防止耳机线折断增长使用寿命。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含 在本发明的保护范围之内。
