LOUDSPEAKER

摘要

A module of loudspeaker 1 for high-quality reproduction of music and voice has a direct radiating base electrodynamic driver (EDD) 2 transforming an electric signal to acoustic one at least in the middle-frequency part of the acoustic frequency range and an enclosure cabinet 3 of this driver 2, the cone 5 of which overlaps the mounting hole in the outside surface of this cabinet. The device is provided with an axial-symmetric acoustic reflector 4 faced the radiating aperture of base EDD 2 and placed outside the enclosure cabinet 5 coaxially with axis 6 of base EDD 2 wherein <DF>0,5 RE < DELTA < 0,25 lambda max, and SR = (1/3 DIVIDED 4)SE , </DF> where RE - radius of the effective area of the radiating surface of base EDD 2; DELTA - distance from the radiating aperture of base EDD 2 to the acoustic reflector 4; lambda max - maximal acoustic wavelength in air, which is reproduced by base EDD 2; SR - area of acoustic reflector 4; SE - effective area of the radiating surface of base EDD 2. The device may have a direct radiating low-frequency EDD with the corresponding acoustic reflector of the low-frequency radiation and also high-frequency electrodynamic drivers. <IMAGE>
