The invention discloses a siphon type straight air exhaust sound receiving box, and belongs to an industrial product. The siphon type straight air exhaust sound receiving box comprises a centrifugal motor, an inner holed sound receiving wall, a middle holed sound receiving wall, an outer holed sound receiving wall, a plurality of foam balls different in size, a sound insulation sponge a and a sound insulation sponge b. The siphon type straight air exhaust sound receiving box is characterized in that the centrifugal motor is covered with the inner holed sound receiving wall, the inner holed sound receiving wall is covered with the middle holed sound receiving wall, the foam balls are fixed to the inner side of the top of the middle holed sound receiving wall in a suspension mode, the middle holed sound receiving wall is covered with the outer holed sound receiving wall, the sound insulation sponge a is attached to the inner holed sound receiving wall, and the sound insulation sponge b is attached to the middle holed sound receiving wall. The siphon type straight air exhaust sound receiving box has the advantages that noise generated by the centrifugal motor is attenuated in a hedging mode layer by layer through the inner wall, the sound insulation sponge a, the middle wall, the sound insulation sponge b, the foam balls and the outer wall, and therefore the sound receiving function is achieved.
Description
[0001] The invention relates to an industrial product, more specifically a wind exhaust nanoacoustic device. Background technique [0002] Ordinary exhaust devices are only covered with a shell with an exhaust outlet on the outside of the air source, which cannot effectively reduce the noise produced by the air source, so that workers cannot work in a noisy environment with peace of mind. Contents of the invention [0003] The object of the present invention is to provide a nanosonic box capable of effectively sonicating to meet more industrial production needs, so that workers can work in a relatively comfortable environment. [0004] The purpose of the present invention can be achieved in the following ways: a rainbow-type direct-exhaust wind nano-acoustic box, including a centrifugal motor, a sound-insulating sponge a, a holed nano-acoustic inner wall, a sound-insulating sponge b, and a holed nano-acoustic middle wall, ranging in size A number of foam balls, with open-hol...
