This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1 and 2, a conference room public address method of the present invention is schematically shown, including:
step S10, obtaining the public address data of the array sound pickup assembly, where the array sound pickup assembly includes a plurality of sound pickup devices 600 arranged in a matrix, and the public address data includes the identification information of the sound pickup devices 600 and the audio signals collected by the sound pickup devices 600. Specifically, each sound pickup apparatus 600 has its own identification information, and a specific sound pickup apparatus 600 can be located by the identification information.
Step S11, determining whether the volume of the audio signal satisfies the positioning threshold, if yes, executing step S12. The locating threshold is a preset volume threshold, and when the volume of the audio signal exceeds the locating threshold (in some optional embodiments, the locating threshold is 70dB), the step S12 is continuously executed, and if the volume of the audio signal does not exceed the locating threshold, the step S10 is repeated to continuously acquire the audio signal.
Step S12, the sound pickup device 600 with the largest volume for collecting audio signals is screened, and the sound pickup device 600 is recorded as the positioning sound pickup device 600, wherein during screening, the volumes of the audio signals collected by the plurality of sound pickup devices 600 are compared, the audio signal with the largest volume is selected, and the sound pickup device 600 collecting the audio signal is marked as the positioning sound pickup device 600. In fact, it can be determined by the positioning sound pickup apparatus 600 that the speaker is located near the positioning sound pickup apparatus 600.
Step S20, determining the speaking position of the speaker in the conference room according to the identification information of the positioning sound pickup device 600 and the audio signal, because the plurality of sound pickup devices 600 are pre-installed in the conference room and each sound pickup device 600 has the identification information, the position of the sound pickup device 600 in the conference room can be known according to the identification information, and then the speaking position of the speaker can be known, so that the speaking position of the speaker can be known by collecting the audio through the array sound pickup assembly.
Step S30, adjusting the amplification intensity of each speaker device 700 in the array speaker assembly according to the speaking position, where the array speaker assembly includes a plurality of speaker devices 700 arranged in a matrix, and the speaker devices 700 play the audio signal according to the amplification intensity. Specifically, the amplification intensity of each speaker device 700 increases as the distance between the speaker device 700 and the speaking position increases, that is, the amplification intensity of the speaker device 700 farther from the speaking position is higher than that of the speaker device 700 closer to the speaking position, which allows the conference participants farther from the speaker to hear the voice of the speaker through the speaker device 700, while the conference participants closer to the speaker can hear not only the voice of the speaker through the speaker device 700 but also the voice of the speaker himself, and the voice of the speaker himself is kept to the maximum.
In some optional embodiments, the conference room includes a first area 800 and a second area 900 disposed around the first area 800, specifically, the first area 800 is a rectangular area in the middle of the conference room, and the second area 900 is a square ring area around the conference room. When the speaking position is in the first area 800, the sound amplification intensity of each speaker device 700 increases as the distance between the speaker device 700 and the speaking position increases, so that the conference participants who are farther away from the speaker can hear the sound of the speaker through the speaker device 700, and the conference participants who are closer to the speaker can hear not only the sound of the speaker through the speaker device 700 but also the sound uttered by the speaker himself/herself. When the speaking position is in the second area 900, the sound amplification intensity of each speaker device 700 is uniform, and it is because the sound-absorbing material is disposed on part of the wall of the conference room, most of the sound spoken by the speaker standing in the second area 900 will be absorbed by the sound-absorbing wall of the conference room, so that it is difficult for the conference participants far away from the speaker to hear the sound of the speaker, and therefore, the sound amplification intensity of each speaker device 700 needs to be adjusted to be uniform.
As shown in fig. 3, in order to solve the same technical problem, the present invention also provides a conference room public address set, comprising:
audio acquisition module 100 for obtain array pickup assembly's public address data, array pickup assembly includes a plurality of pickup apparatus 600 that are the matrix and arrange, and public address data includes pickup apparatus 600's identification information and the audio signal that pickup apparatus 600 gathered.
And the positioning module 200 is configured to determine a speaking position of the speaker in the conference room according to the identity information and the audio signal.
The public address adjusting module 300 is configured to adjust the public address intensity of each loudspeaker 700 in the array loudspeaker assembly according to the speaking position, where the array loudspeaker assembly includes a plurality of loudspeakers 700 arranged in a matrix, and the loudspeakers 700 play the audio signal according to the public address intensity.
The screening module 400 is configured to screen the sound pickup apparatus 600 that collects audio signals and has the largest volume, and record the sound pickup apparatus 600 as the positioning sound pickup apparatus 600.
A threshold determining module 500, configured to determine whether the volume of the audio signal meets a positioning threshold.
