The invention relates to a silencer, a preparation method of the silencer, an air conditioner and an automobile, the silencer comprises a shell, an inner container and a power supply device, a first cavity is formed in the shell, the inner container is made of a piezoelectric material, the inner container is arranged in the first cavity, and the power supply device is electrically connected with the inner container. The inner container is laid on the inner wall of the silencer, the inner container is made of the piezoelectric material, the inverse piezoelectric effect of the piezoelectric material is utilized, that is, the inner container laid in the silencer is powered on, the inner container deforms towards the center position of the silencer, and the purpose of adjusting the length and the expansion ratio of an expansion cavity in the silencer can be achieved; continuous adjustment of the noise elimination amount of the silencer is achieved, the noise elimination amount is increased under the condition that the structural appearance of the silencer is not changed, and the noise elimination performance of the silencer is improved.
本公开是关于一种消音器、消音器的制备方法、空调及汽车,所述消音器包括壳体、内胆以及供电器,所述壳体内设置有第一腔,所述内胆的材质为压电材料,所述内胆设置在所述第一腔内,所述供电器与所述内胆电连接。本公开通过在消音器的内壁上敷设内胆,且内胆的材质为压电材料,利用压电材料的逆压电效应,即给敷设在消音器内部的内胆通电,使内胆向消音器的中心位置发生变形,可以达到调整消音器内部扩张腔长度及扩张比的目的,实现了消音器消声量的连续调节和在不改变消音器结构外形情况下增大消声量,提高了消音器的消声性能。
