With the continuous upgrading of household appliance technology, voice control has become a standard function. IPRO acoustic vents provide comprehensive protection for acoustic components of various household appliances, including range hoods, sweeping robots, gas water heaters, intelligent doorbells, intelligent toilets, electric razors, electric toothbrushes, bathroom control panels, etc. For example, the IPRO acoustic vent installed at the microphone and speaker areas of the range hoods not only blocks the entry of oil fume, but also maintains a perfect sound transmission.
