Abstract

PURPOSE:To remove resonance of a dome and to improve an acoustic pressure frequency characteristic, by providing an air vent having 1/100-1/10 area of the whole surface area of the dome, on the dome of a loudspeaker of which an edge and a dome are formed to one body by use of resin. CONSTITUTION:An air vent 14 is provided on a dome 2 of a loudspeaker consisting of an edge 1 and the dome 2 which have been molded to one body. In this case, size of the air vent is made >=1/100 of an area of the dome 2 in order to make air resistance small enough, and also is made <=1/10 of the area of the dome 2 in order to control a drop of acoustic pressure within 1dB. According to this constitution, compliance by an air chamber 10 in the dome 2 is removed, and unnecessary unevenness of an acoustic pressure frequency characteristic is suppressed.
