Abstract

该花岗岩音箱仍具有箱体、喇叭,其特点是花岗岩制成的箱体其内表面呈粗糙不规则凹凸状。具有上述结构特点的本实用新型利用天然石材特有的物理性能与结构,完全消除了音箱设计制作中最难克服的箱体自谐振及驻波共振等不利因素。

Description

花岗岩音箱
本实用新型关于一种音箱。
传统的音箱采用木质或胶合板材做为箱体材料，这种材料属固体有机物，一般固体有机物的谐振频率约100HZ以下，当物体在它的谐振点附近时，只要外加能量很小的振幅，就能使物体产生很大的振幅，即为材料的自谐共振，所以用木材做音箱，它的谐振频率落在人耳可闻的频段内，音箱工作时，实际上人耳听到的不完全是扬声器发生的纯净的低音，同时还夹杂箱体振动时发生的不需要的有害音质的混合声，也称”声染色”，木质板材制作的音箱，其箱体内表面平整光滑的结构，很容易受到箱内驻波叠加干扰，产生损害音质的驻波共振，可以肯定带有“声染色”效应和驻波箱振的音箱不是一个真正的高保真声音重放系统。
本实用新型之目的就是要克服现有技术存在的不足而提供一种结构及其相应材质合理、可靠的花岗岩音箱。
该花岗岩音箱仍具有箱体、喇叭，其特点是花岗岩制成的箱体其内表面呈粗糙不规则凹凸状。
具有上述结构特点的本实用新型利用天然石材特有的物理性能与结构，完全消除了音箱设计制作中最难克服的箱体自谐振及驻波共振等不利因素。
附图1为本实用新型实施例结构剖视图。
如图所示箱体1系花岗岩材料，根据需要及音箱对喇叭2分布的要求设置相应的喇叭2，箱体2内装面最好是全部呈粗糙不规则凹凸状，这种花岗石箱体2表面形成的粗糙不平不规则起伏的结构特点正好破坏了有序反射的条件，使入射波与反射波不再沿轴向相向方向传播，而以杂乱无序散射的方式使声波能量均匀分布于箱室内，非常有效地抑制驻波的形成，使音箱设计中最为有害的叠加驻波共振荡然无存。
