Abstract

PURPOSE:To harmonize a ventilator with an acoustic device by detecting noise at the time of operating the ventilator and varying an output of a speaker in response to the detected noise in the ventilator with a speaker function to be mounted behind a ceiling. CONSTITUTION:A connection port 3 connected to a ventilator to become a supplied air suction inlet or discharge outlet is formed at one side face of a box-shaped body box 2 in which its lower surface is opened and a sound absorber 1 is lined on its inner surface to be able to be connected to a duct. A decoration panel 4 is detachably mounted on the lower surface. An indoor air supply/ discharge gap 5 is formed between the panel 4 and the box 2, and a speaker 6 is mounted. An external voice signal 8 is input to the speaker 6 through sound volume and tone control means 9. When noise at the time of operating the ventilator is detected by a sensor 11 disposed in the gap 5, etc., and input to control signal generating means 10, the means 10 forms a control output of the speaker 6 responsive to the magnitude of the noise, thereby controlling the output of the speaker 6.
