Abstract
PURPOSE: To prevent the speaker from rain water and to exclude the interference of car chamber due to resonance, allowing to reproduce audio in excellent manner, by providing the sound absorption body of foam and perforated material having a specific porosity and the thin film of non-porosity covering the outside.
CONSTITUTION: The porous sound absorbing body 6 such as polyurethane foam and felt is formed at the back of the speaker 1 fitted to the door 2 having the window glass 3 so that the porosity can be less than 70cc/cm2/second by taking it as the thickness of 10mm. The thin film 7 of non-porosity such as polyvinyl and silicone resin is laminated outside the main body 6 or sticked. The thickness of the film 7 can be below 200μ. By constituting the sound absorbing body 5, the through- hole 8 having the sectional area of 1W100% to the front aperture area of the speaker 1 is provided with the sound absorption body 5 to improve the sound absorption of low frequency band.
