Problems solved by technology

However, there are still defects in the microphone array in the prior art, which affect the sound collection and extraction of the robot's voice interaction. For example, due to the problem of the microphone installation structure, many sounds cannot be directly received by the microphone, but will be reflected. Ensure the directness of the sound source and form a masking effect; in addition, since the robot is equipped with a speaker in addition to a microphone, the sound from the speaker can easily interfere with the microphone from the cavity in the robot

Abstract

A microphone array structure of a robot comprises at least two microphones which are installed on the robot, installation holes which are used for installing the microphones and correspond to the microphones in number are formed in a shell of the robot, the microphones are installed in the installation holes, and no shielding object exists above the top faces of the microphones. The microphone array structure has the beneficial effects that the human sound energy directly reaches each microphone, so that the accuracy is improved when the microphones collect and extract the sound. The sound isprevented from leaking from the inside of the shell.

Description

technical field [0001] The invention relates to a robot, in particular to a microphone array structure of the robot. Background technique [0002] Anything that involves voice interaction between humans and robots is inseparable from the collection and extraction of sounds. As far as the current intelligent robots are concerned, sound extraction and collection in voice interaction are even more important. The accuracy of sound collection and extraction is an important point of user experience. [0003] Then came the microphone array, which refers to a system that uses multiple microphones to sample and process the spatial characteristics of the sound field. The microphone array can achieve multiple effects such as noise suppression, echo suppression, and reverberation. However, there are still defects in the microphone array in the prior art, which affect the sound collection and extraction of the robot's voice interaction. For example, due to the problem of the microphone ...
