Microphone Array Features:
A microphone array is a system that consists of a certain number of acoustic sensors (generally microphones) that sample and process the spatial characteristics of the sound field. Its main functions are sound source location, suppression of background noise, interference, reverberation, echo, and signal extraction and separation. Sound source localization refers to the use of a microphone array to calculate the angle of the sound source from the array, and to track the target sound source based on TDOA (Time Difference Of Arrival). Signal extraction and separation refers to effectively forming a beam in the desired direction, only picking up the signal in the beam, so as to achieve the purpose of extracting the sound source and suppressing noise at the same time: In addition, the information provided by the microphone array can be effectively realized based on the deep neural network. The reverberation is removed, which greatly improves the effect of voice interaction in real application scenarios.
Hardware Introduction:
The microphone array adopts a planar distributed structure, including 6 microphones, which can achieve 360-degree equivalent sound pickup, and the wake-up resolution is 1 degree. You can use the microphone array to get the original and reduced noise frequency, get the wake-up angle, and the main microphone number.
Applications:
- Ackerman differential cars
- Mecanum wheel cars
- Omni wheel cars
- Tracked cars
- 4WD cars
Package Included:
- 1 x Set of Voice Module
