VEHICLE ENGINE SUSPENSION ASSEMBLY Russian patent published in 2013 - IPC B60K5/12 F16F13/00 

FIELD: transport.

SUBSTANCE: invention relates to automotive industry, particularly, top-rank cars exploiting acoustic vibrations for warning the drive about engine operating conditions. Proposed assembly differs from known designs in that acoustic signal generator 7 is composed of hollow deformable chamber 8 confined by elastic sidewall 9 and top and bottom covers 10, 11 connected with support attachments to engine 2 and vehicle body structural element 3. Restricting hole 12 s made in one of said covers 10, 11. Inner space of chamber 8 is communicated via restricting regular 19 with car drive cabin by air tube 14, 25 that houses separation diaphragm 15. Wall 9 is made of elastic polymer material, for example, rubber, and shaped to, preferably, bellows. Sound-transmitting absorbing baffle 17 made of porous material is arranged in tube 14, 25 nearby its outlet end 16. Diaphragm 15 is arranged in extra hollow chamber 18 integrated in tube 14, 25. Intrinsic frequency of free vibrations of diaphragm 14 in chamber 13 falls in the range of desirable warning sound.

EFFECT: comfortable noise in car cabin.
