Title:
ACOUSTIC DEVICE WITH VENTILATION FUNCTION AND ELEVATOR SYSTEM
Document Type and Number:
Japanese Patent JP2023122019
Kind Code:
A
Abstract:
To form an acoustic environment capable of improving sound quality in a ventilated space while ventilating the ventilated space.SOLUTION: An acoustic device with a ventilation function comprises an acoustic duct provided in a ventilated space of a ventilation target and having an inlet port and an exhaust port, a fan provided in the acoustic duct and exhausting air sucked from the inlet port to the ventilated space through the exhaust port by performing rotational drive, and two or more speaker cabinets provided on the acoustic duct and radiating acoustic waves toward the inside of the acoustic duct. Each of the speaker cabinets has a speaker unit having a radiation plane for radiating acoustic waves, the radiation plane being arranged toward the inside of the acoustic duct. The acoustic wave radiated from the radiation plane is radiated toward the ventilated space from the exhaust port of the acoustic duct. The wall surface of the acoustic duct forms a channel for ventilation air flowing from the inlet port to the exhaust port and functions as a diaphragm.SELECTED DRAWING: Figure 5
