Description

一种双喇叭式入耳式耳塞 技术领域
本实用新型涉及一种入耳式耳塞，更具体地说，涉及一种双喇叭式入耳式耳塞。
背景技术
随着信息科技的发展与进步，各式各样的科技产品正不断地进入人们的日常生活当中，此外，这些科技产品正逐渐地影响并改变着人们的生活。其中，耳塞作为一种音频输出装置而被广泛应用于人们的生活中，对于各种音频播放设备来说，耳塞已经成为一种必要装置。
随着人们对耳塞质量要求的不断地提高，基本的音频输出功能已经远远不能够满足人们的要求，耳塞的音质效果越来越被人们所重视，耳塞的音质效果已经成为评价耳塞质量的一个重要参照。然而，现有技术中的耳塞一般仅在壳体内安装一个喇叭，其仅能发出单一频率的声音，完全不能实现高、低音频互补，声音的立体感效果较差；针对于此，现在市面上出现有双喇叭甚至是多喇叭的耳塞，如中国专利申请号ZL201410151138.1，申请公告日为2014年8月6日，发明创造名称为：双喇叭耳机，该申请案涉及一种双喇叭耳机，包括有壳体、固定件、高音喇叭以及低音喇叭，该壳体内具有一第一出音通道和一容置空间，所述固定件安装于该容置空间内，该固定件的两端分别设有一第一容置腔以及第二容置腔，所述高音喇叭安装在该第一容置腔内，所述低音喇叭安装在所述第二容置腔内，该高音喇叭的出音侧面正对连通前述第一出音通道，该高音喇叭的外壁面与第一容置腔的内壁之间形成一第二出音通道，该第二出音通道连通第一出音通道，该低音喇叭的出音侧面正对连通该第二出音通道。该申请案中高音喇叭和低音喇叭均设置在固定件内，且高音喇叭设置在低音喇叭的前方，高音喇叭的声音能够直接通过第一出音通道向外传播，而低音喇叭发出的声音必须经第二出音通道后从第一出音通道向外传出，又因为低音喇叭是为发散型发声的，因此将高音喇叭设置在低音喇叭的前方使得低音喇叭发出的声音部分会被高音喇叭阻挡，进而造成声音耗损的问题。
