Title:
ACOUSTIC MATERIAL STRUCTURE AND METHOD FOR ASSEMBLING SAME AND ACOUSTIC RADIATION STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2018/192484
Kind Code:
A1
Abstract:
An acoustic material structure and a method for assembling same and an acoustic radiation structure. The acoustic material structure comprises an acoustic unit. The acoustic unit is used for attaching to a surface of the acoustic radiation structure (1). The acoustic unit comprises: a sheet (2), a cavity (4) being provided between the sheet (2) and the acoustic radiation structure (1); and an opening (3) running through the acoustic unit, one end of the opening (3) being communicated with the cavity (4). The opening (3) can reduce the spring effect of a medium in the cavity (4), so that the acoustic unit attached to the surface of the acoustic radiation structure can also achieve a low frequency sound insulation effect. The acoustic unit may further comprise a supporting body (5), a mass block (6), and a constraining body (63). The operating frequency of the acoustic unit can be adjusted by means of the supporting body (5), the mass block (6), and the constraining body (63).
