Referring to fig. 1 to 3, an embodiment of the invention provides a multipoint far-field voice interaction device, which includes:
The microphone assembly comprises a plurality of microphones 20, and the microphones 20 are arranged in gaps formed by adjacent Micro LED lamp beads 11.
And the controller 30 is electrically connected with the display screen 10 and the microphone assembly to control the operation of the Micro LED lamp beads 11 on the display screen and receive the voice signals collected by the microphone assembly.
In this embodiment, the multipoint far-field speech interaction device is an electronic device with a display screen, such as a television, an intelligent tablet or other tablet, and the present invention is not limited in particular. Wherein, especially, the display screen of the multi-point far-field voice interaction device is a Micro LED-based display screen. And the distance between the adjacent Micro LED lamp beads is 0.5mm to 1 mm.
In the present embodiment, the microphone assembly includes a plurality of microphone arrays, each distributed in a different area of the display screen 10, for collecting voice signals from a plurality of directions; wherein each microphone array forms a path of voice signal.
For example, as shown in fig. 1, the number of the microphone arrays is 5, and the 5 microphone arrays include a first microphone array 21 disposed at an upper left area of the display screen 10, a second microphone array 22 disposed at an upper right area of the display screen 10, a third microphone array 23 disposed at a lower left area of the display screen 10, a fourth microphone array 24 disposed at a lower right area of the display screen 10, and a fifth microphone array 25 disposed at a center position of the display screen 10.

Specifically, the controller 30 performs a voice interactive operation as an example. The controller 30 is specifically configured to:
firstly, filtering voice signals outside a human voice signal frequency range through a band-pass filter to obtain five paths of filtered voice signals; the voice signal is an analog signal.
Because the frequency range of human voice signals of people is concentrated between 260Hz and 3100Hz, signals below 260Hz and above 3100Hz are filtered by a band-pass filter, and only voice signals between 260Hz and 3100Hz need to be reserved.
And then, filtering noise of the five paths of filtered voice signals by utilizing phase interpolation.
The principle of phase interpolation is that the difference is measured and calculated according to the different distances between each microphone array and a sound source, then delay is carried out, the distance far away is used as noise, and the distance near the distance far away is used as required voice. The person calculates the 1kH phase at different positions, up to the latest as noise. Delaying to the opposite phase, and performing addition and subtraction operation with the required voice to remove noise.
As shown in fig. 5 and 6, the specific process is as follows:

adding a voice signal a1 acquired by the first microphone array, a voice signal a3 acquired by the second microphone array, a voice signal a4 acquired by the third microphone array, a voice signal a6 acquired by the fourth microphone array and a voice signal a7 acquired by the fifth microphone array, and subtracting b1 and b2 to obtain a voice signal c; the speech signal c is the speech signal with the environmental noise filtered.
Then, the voice signal with noise filtered is filtered, amplified and AD converted to obtain a digital voice signal;
and finally, executing corresponding voice interaction operation according to the digital voice signal.
In this embodiment, for example, after the final digital voice signal is obtained, voice recognition may be performed on the final digital voice signal to obtain corresponding text data, and then the text data is recognized to generate a corresponding control instruction, so as to implement control on the multi-point far-field voice interaction device according to the control instruction, for example, control on, off, channel change, volume adjustment, and the like of the multi-point far-field voice interaction device.
In conclusion, the multi-point far-field voice interaction device provided by the embodiment realizes the non-shielding installation of the microphone 20 on the premise of not additionally arranging a frame by arranging the microphone 20 between the gaps of the Micro LED lamp beads 11. The embodiment can get rid of the limitation of the traditional microphone to the exposed structural part, so that the display screen can realize a real frameless design.
