Abstract

PURPOSE:To control the directivity, by fixing plural speaker units for the same frequency band at proper intervals and giving a level difference, a time difference, and a phase difference to speaker units. CONSTITUTION:A woofer 2 is fixed in the lower part of the front of a speaker box 1, and one side in the upper part of the front is cut to form a slope 3, and tweeters 41 and 42 are fixed to the upper part of the front of the speaker box 1 and the slope 3. When a pair of speaker systems is so installed that tweeters 42 fixed to slopes 3 are placed nearer to walls of a listening room 6, tweeters 41 provided in upper parts of the front of speaker boxes 1 take charge of direct sound components to a listener 7, and tweeters 42 provided on slopes 3 take charge of reflected sound components. Attenuators 52 and 53 are operated to change input signal levels to tweeters 41 and 42, thus making them suitable for the sound absorptivity of walls or the like to obtain an optimum reproducing sound field. Delay elements are effective besides attenuators.
