Abstract: To provide a sound absorbing structure having a superior sound absorbing characteristic and an external appearance of the sound absorbing structure which does not cause flicker or the like, by disposal, for example, in the front of an air chamber, a plurality of ribs (2a) are disposed on one surface of the sound absorbing board body (2), and a plurality of through-holes (3) are provided in basal portions (2b) between the ribs (2a) to form a porous structure. Concealing materials (5) are provided between the ribs (2a) of the sound absorbing board body to conceal the through-holes (3), respectively.

Abstract: A sound absorbing structure including a sound absorbing member, an air layer, and a resonant sound absorbing structure. The air layer is formed in the rear of the sound absorbing member. The resonant sound absorbing structure includes a slit and is formed in the rear of the sound absorbing member. The sound absorbing member is a surface plate covering the rear air layer and the resonant sound absorbing structure, and the sound absorbing member is shaped in one of a plate and plane.
