Description
技术领域
本发明涉及音响设备技术领域，特别是涉及一种吸顶式平板音响。
背景技术
音响是指除了人的语言、音乐之外的其他声响，包括自然环境的声响、动物的声音、机器工具的音响、人的动作发出的各种声音等。音响主要包括功放、周遍设备（包括压限器、效果器、均衡器、VCD、DVD等）、扬声器（音箱、喇叭）调音台、麦克风、显示设备等等。其中，音箱就是声音输出设备、喇叭、低音炮等等。一个音箱里通常包括高、低、中三种扬声器。
随着科技的发展出现了一种藏墙式音响，这种音响采用180度平面发声无锥形喇叭且音箱与艺术相结合，使得音箱就是画，是传统音响的替代品，而且这种音响十分小巧能够嵌入在墙壁内，不会占用室内空间。这种音响具有超溥、智能、节省空间等特性；它适用于家庭个性化装饰，咖啡厅、茶馆、餐厅、电教室、会议室、酒店、公众交通工具、公众休闲娱乐场所、公众广播等场所。现有的藏墙式音响在安装时通常需要先在墙壁上凿出个和音响大小相互匹配的安装洞，由于藏墙式音响安装在墙壁内，因此需要对墙壁进行适当的处理，以避免灰尘的进入，导致音响损坏，因此安装起来相当不便。
发明内容
本发明所要解决的技术问题是提供一种吸顶式平板音响，使得音响安装过程方便，并且能够提升音响音质。
本发明解决其技术问题所采用的技术方案是：提供一种吸顶式平板音响，包括发声板、声音传感器和音效室，所述发声板背面安装有所述声音传感器，所述声音传感器与音效室内的驱动器相连，所述音效室安装在发声板背面；所述发声板安装在天花吊顶上。
所述声音传感器共有四个，所述四个声音传感器的连接线呈平行四边形。
所述的平行四边形较小的夹角满足以下公式：
其中，A为平行四边形的短边长度；B为平行四边形的长边长度；C为声音传感器的频响系数，α为平行四变形中较小的夹角。
所述声音传感器位于所述音效室内。
所述发声板和音效室之间还设有泡棉条。
所述音效室的顶面为网格结构。
有益效果
由于采用了上述的技术方案，本发明与现有技术相比，具有以下的优点和积极效果：本发明能和普通的天花吊顶，完全融合，巧妙的充分利于吊顶后的巨大顶部空间，形成音响箱体，大大提升低频表现，便于简单安装、维护、非常适合于公共空间。
附图说明
图1是本发明的爆炸图。
具体实施方式
下面结合具体实施例，进一步阐述本发明。应理解，这些实施例仅用于说明本发明而不用于限制本发明的范围。此外应理解，在阅读了本发明讲授的内容之后，本领域技术人员可以对本发明作各种改动或修改，这些等价形式同样落于本申请所附权利要求书所限定的范围。
本发明的实施方式涉及一种吸顶式平板音响，如图1所示，包括发声板1、声音传感器2和音效室3，所述发声板1背面安装有所述声音传感器2，所述声音传感器2与音效室3内的驱动器相连，所述音效室3安装在发声板1背面，并使所述声音传感器2位于所述音效室3内；所述发声板1安装在天花吊顶上。其中，发声板1的板面的尺寸大小可根据实际安装需要，进行现场裁切。
本发明在安装时，只需要在原先的天花吊顶上取下一块后再将本发明安装到天花吊顶空缺的位置，安装固定方式与普通的天花吊顶，即安装主龙骨、安装副龙骨、安装吸顶式平板音响，由于本发明的发声板与天花吊顶的形状相互匹配，因此可以和天花吊顶完全融合，为了使天花吊顶看上去更为自然，可在发声板表面贴上与天花吊顶图案相互匹配的墙纸等等。
所述发声板1和音效室3之间还设有泡棉条4，从而形成两层新型结构。其中，泡棉条4最好使用的是高密度的泡棉条，其硬度适中即可。改变原来的二层刚性连接结构，可以克服无法接入震动音源的缺点，大大改善音质，且在小震动下对墙体没有损伤、减震，同时原来的二层刚性结构束缚了震动的空间，利用高密度泡棉条可以使低频的效果更好。
所述声音传感器2共有四个，所述四个声音传感器2的连接线呈平行四边形，如此设置可以提高音响的音质效果。形成的平行四边形中较小的夹角满足以下公式：
其中，A为平行四边形的短边长度；B为平行四边形的长边长度；C为声音传感器的频响系数，α为平行四变形中较小的夹角。
所述音效室的顶面为网格结构，采用网格结构可以充分利用天花吊顶后的巨大顶部空间，形成音响箱体，产生更好的音质和更好的低音效果。
不难发现，本发明能和普通的天花吊顶，完全融合，巧妙的充分利于吊顶后的巨大顶部空间，形成音响箱体，大大提升低频表现，便于简单安装、维护、非常适合于公共空间。
