PURPOSE: To provide a trunk resonator for reducing the specific confined sound in a car room, by using a trunk room as resonator for the sound hall in a car room. CONSTITUTION: A resonator is constituted by drilling a hole (e) having a flange part (d) formed at the peripheral edge of a panel (c) installed between a car room (a) and a trunk room (b), forming the trunk room (b) as cavity, when the car room (a) is used as sound hall, and using the hole (e) having the flange part (d) formed, a neck part, and the max. sound absorbing frequency of the resonator which is determined according to the sectional area of the hole (e), height of the flange part (d), and the capacity of the trunk room is tuning- performed in a specific confined sound frequency region in the car room (a). |
