 本发明的实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
参阅附图1-附图10，一种物理扩音装置，用于手机1，手机1上设有扬声器出声孔10，该物理扩音装置还包括扩音音箱2，扩音音箱2还设有空气腔道20，空气腔道20分为进音腔道201和出音腔道202，进音腔道201第一端为进音口23，进音口23与扬声器出声孔10紧密贴合，出音腔道202一端与进音腔道201的第二端连接，另一端在扩音音箱2内延伸并穿透其一外壁且穿透处为出音口24，进音腔道201的第一端与第二端之间设有喉口230，出音口24的面积大于喉口230的面积。
具体的，扩音音箱2在与扬声器出声孔10紧密贴合处均设有进音口23，扬声器出声孔10所播放出的声音从进音口23进入并沿空气腔道20传播至出音口24处，再从出音口24处扩音发出，实现提高手机1扬声器的播放音量和播放效果的功能。同时，由于利用了号筒扩音的原理，该物理扩音装置全过程无需电源供电，并且可随时随地的实现该装置的扩音功能。
进一步的，为了便于实际生产中空气腔道20的成型，扩音音箱2包括固定箱21和腔道柱22，进音口23和进音腔道201设置在固定箱21上，固定箱21上还设有柱形孔210，腔道柱22固定安装于柱形孔210中，出音腔道202设置于腔道柱22上。
进一步的，腔道柱22的一端还设有定位凸台220，固定箱21上柱形孔210的一端设有定位槽211，定位凸台220固定安装于定位槽211中。上述设置用于腔道柱22在柱形孔210中的定位，确保腔道柱22上的出音腔道202与固定箱21中的进音腔道201顺畅连接。
进一步的，本发明的其中一种实施例中，出音口24设置于腔道柱22上的一侧端。
进一步的，本发明的其中一种实施例中，出音口24设置于固定箱21的外侧壁。
进一步的，出音腔道202在伸出扩音音箱2的部分由喇叭形状的管状结构形成，形成如同留声机外放声音的喇叭形状结构。
进一步的，进音口23的面积大于喉口230的面积，进音口23与喉口230之间形成空气压力腔室结构。扬声器出声孔10发出的声音振动并挤压空气，使空气从相对较大的空间进入相对较小的空间，增加空气流速，提高声音的传播速度，因而也加大了声辐射阻抗，减少发出的声音失真。
进一步的，空气腔道20在靠喉口230一侧截面积缓慢增大，靠出音口24一侧截面积快速增大。空气腔道20的长度以及出音口24面积的大小，密切关系着其播放出声音的特性。空气腔道20在靠近喉口230的一侧，呈细长状缓慢增大；靠出音口24的一侧，截面积快速增大，以使出音口24面积尽可能增大，从而降低可播放声音的最低频率。
进一步的，空气腔道20中声音的传播行程越长，空气腔道20播放出的声音频率越低。空气腔道20长度越长，经手机1外放发出的声音频率越低，即低音效果越好。
进一步的，为了尽可能的增加空气腔道20的长度，出音腔道202盘绕设置于腔道柱22上。
进一步的，扩音音箱2上还设置有用于放置手机1的倾斜平面和用于固定手机1的沟槽，进音口23设置于沟槽中或垂直于所述倾斜平面的平面上。该扩音装置也起到了作为手机支架的作用，解放使用者的双手，为使用者提供方便。
进一步的，扩音音箱2设有多个进音口23和多个喉口230形成多条空气腔道20，而多条空气腔道20均共用一个出音口24，或多条空气腔道20设置有多个出音口24。上述设置使该装置平放于放置平面或竖放于放置平面，均不影响其功能；同时手机1平放或竖放于该装置上，也均不影响该装置的功能。确保了无论怎么放该装置或手机1，扩音音箱2上与扬声器出声孔10贴合处均有进音口23接收声音。
进一步的，进音口23处还设有密封圈。密封圈的设置使进音口23与扬声器出声孔10贴合更紧密。
