Abstract

PURPOSE:To improve the howling preventing effect, and to enlarge the degree of freedom at the time of using by constituting the titled device of a main transmission line consisting of an input part, a converting part of a multi-sequence, an amplifying part and an output part, and a control part for selecting one transmission line of transmission lines of a multi- sequence by receiving a signal of the input part. CONSTITUTION:This device is constituted of an input part 1 consisting of a microphone and a correcting device, a converting part 2 consisting of phase converters which have formed plural phase converters to two paths, and a selector, an amplifying part 3, an output part 4 consisting of a loudspeaker, a high-pass filter, a low-pass filter, a frequency converter 6, and a control part 5 consisting of a computing element. As for a sound signal which is inputted to the control part 5, in a state that howling is generated, a voltage output of a high frequency or a low frequency continues to remain a reference potential. In such a case, the computing element decides whether a high frequency portion of the sound signal is the reference potential or not, and whether a low frequency portion is the reference potential or not, detects howling in a main transmission line, receives the result of its decision, controls the selector in the converter 2, and switches a transmission path which the sound signal has passed through until that time to a transmission path having an entirely different phase characteristic.
