Anti-howling system for artificial intelligence conference

Abstract

The invention discloses an anti-howling system for an artificial intelligence conference, and particularly relates to the anti-howling field, the anti-howling system comprises an inner shell and an outer shell sleeving the inner shell, the inner shell is detachable, the top of the inner shell is provided with a loudspeaker used for sounding, the outer shell comprises a top plate attached to the top of the inner shell, and the top plate is provided with a plurality of through holes; the bottom of the edge of the top plate is provided with an interlayer part for sound insulation, a sound insulation plate is attached to the outside of the interlayer part, the interlayer part and the sound insulation plate are used for shielding a radiation area of the loudspeaker, the outer wall of the sound insulation plate is provided with a plurality of microphone heads, and the top and the bottom of the vacuum plate are provided with anti-howling assemblies. The anti-howling assemblies are used for separating the pickup areas of the plurality of microphone heads from the radiation area of the loudspeaker. According to the invention, when the microphone head is used, the sound playing area of the loudspeaker is avoided, the sound radiation area of the loudspeaker is not overlapped with the use area of the microphone head, and the effect of suppressing audio howling can be well realized.

Description

technical field [0001] The invention relates to the field of anti-howling, and more specifically, the invention relates to an anti-howling system for artificial intelligence conferences. Background technique [0002] The use of voice systems is common. For example, in a teleconferencing system, the participants are usually gathered in an office or conference room and are seated at different locations in the room. The rooms being used are often not equipped with special sound-cutting materials, and echoes of near-end and far-end sounds add to the noise level. If the room is large enough, some participants can sit away from the phone table, keeping themselves away from the microphone. Some participants may not actively speak, or speak only occasionally. However, their presence increases the number of noise sources in the room, as pencils are tapped, papers rustle, and private conversations are produced. These noise sources further degrade the sound quality experienced by t...

AI Technical Summary

Problems solved by technology

For example, the acoustic echo from the feedback in the acoustic path between the speaker of the phone and its microphone, since the speaker and the microphone are installed in the same box, the sound vibration from the speaker will be transmitted to the microphone, which will affect the sound pickup effect of the microphone
