Sound absorption device capable of adjusting sound absorption frequency
The invention discloses a sound absorption device capable of adjusting sound absorption frequency. According to the sound absorption device, a first casing and a second casing are rotationally connected, an opening is formed between the edge of the first casing and the edge of the second casing, a sound absorption filling layer is located between the first casing and the second casing, a sound absorption cavity is formed between the sound absorption filling layer and the opening, the first casing or the second casing rotates to enable an opening angle to change, the sound absorption cavity changes correspondingly, frequency of absorbed sounds also changes, a positioning structure is connected with the first casing and the second casing and enables the first casing and the second casing tobe positioned, and therefore, the adjusted opening angle is fixed. By means of rotation of the first casing or the second casing, the sound absorption cavity changes, and the frequency of the absorbedsounds also changes, so that the sound absorption device can absorb sounds at different frequencies and is suitable for different places; the sound absorption filling layer is detachably connected with a shell, the sound absorption filling layer with different thickness can be replaced through the opening, and the absorption efficiency is changed; and the whole device is simple in structure and convenient to use.
本发明公开了一种能够调节声音吸收频率的吸音装置，第一壳体以及第二壳体转动连接，第一壳体边缘以及第二壳体边缘之间形成开口，吸音填充层位于第一壳体以及第二壳体之间，吸音填充层与开口之间形成吸音腔，第一壳体或第二壳体转动使开口角度变化，吸音腔对应发生变化，吸收的声音频率也随之改变，定位结构与第一壳体以及第二壳体连接并使第一壳体以及第二壳体定位，使调节后的开口角度固定。通过转动第一壳体或第二壳体，吸音腔发生变化，吸收的声音频率也随之改变，由此吸音装置能够吸收不同频率的声音，适用不同场合；吸音填充层与壳体可拆卸连接，通过开口能够更换不同厚度的吸音填充层，改变吸收效率；整个装置结构简单，使用方便。
