Title: Noise suppressor
Inventor: YAMAUCHI NAOKI
IPC: G10K11/178
Filed: 1991-12-09
Abstract: PURPOSE:To improve noise suppression effect without degrading the function native to a transfer passage by arranging a secondary sound source to face the sound wave front of sound wave from a primary sound source and providing a diaphragm with permeability. CONSTITUTION:In a transfer passage 22 for sound wave coming from a primary sound source 21, a speaker 23 which generates the second sound wave through a diaphragm 23b which is set facing the sound wave front of sound wave and provided with a vent hole 23c and a driving process circuit 25 which sends the driving signal for generating the second sound wave with reverse phase characteristics against the sound wave from the primary sound source 21 to the speaker 23 are provided. The wave form of the noise transferred from the primary sound source 21 is detected by a detecting microphone 24 and then signal-processed by the driving process circuit 25. Then, a driving signal is sent to the speaker 23 and the diaphragm 23b of the speaker 23 vibrates to generate the sound wave with reverse phase against the wave form of the noise. Since the sound wave front is coincident with that of the noise, suppression effect of noise improves. Meanwhile, the low speed constant air flow such as ventilation is transmitted outside through the vent hole 23c.
