Problems solved by technology

[0002] Before the meeting, it is usually necessary to manually debug the audio collection equipment (such as the microphone) in the conference system, so that the volume of the output sound can meet the requirements of the meeting, and at the same time, there will be no howling; nowadays, it is usually performed by the staff based on their experience. Repeated adjustments can meet its requirements, and there are disadvantages of slow debugging speed and low debugging accuracy, and the staff who carry out debugging at the same time need certain experience

Embodiment 1

[0037] Embodiment 1. A method for debugging an audio collection device, such as Figure 1 to Figure 3 As shown, in a silent environment (20dB and below), debug N audio collection devices sequentially according to the following method, N≥1:

[0038] Note: During the debugging stage, only one audio collection device is turned on at the same time, that is, each audio collection device is debugged in turn according to the following steps. Since the debugging methods of each audio collection device are the same, only one audio collection device is debugged in this manual. For a detailed introduction, the workflow for debugging a single audio collection device is as follows: figure 1 shown.

[0039] S1. Set the speaker volume of the K-th audio acquisition device as the initial volume, K≤N, the method is as follows:

[0040] Determine whether there is an audio collection device that has been successfully debugged. If it does not exist, the initial volume corresponding to the K-th a...

Embodiment 2

[0082] Embodiment 2, a device for debugging audio collection equipment, such as Figure 4 As shown, it includes an initial volume setting module 1 , a howling detection module 2 and a volume adjustment module 3 which are sequentially connected by signals; the initial volume setting module 1 is connected to the volume adjustment module 3 by signals.

[0083] The initial volume setting module 1 is used to set the voice playback volume of each audio acquisition device as the initial volume;

[0084] The initial volume setting module 1 includes a judgment unit, a volume setting unit and a volume calculation unit, the judgment unit is connected with the volume adjustment module 3, the volume setting unit and the volume calculation unit signal respectively, and the volume setting unit is connected with the howling detection module 2 signals;

[0085] The judgment unit is used to judge whether there is an audio collection device that has been successfully debugged. When it does not e...

Abstract

The present invention proposes a method for debugging audio collection devices, which is applied in a sound field environment below 20dB, and N audio collection devices are sequentially debugged according to the following method, N≥1: S1, and the playback volume of the K-th audio collection device is set as initial Volume, K≤N; S2. Judging whether the audio currently input by the K-th audio collection device produces howling, and when the judgment result is no howling, increase the volume of the speaker according to the adjusted value, and repeat step S2 until it is judged As a result, howling is generated, and the volume of the speaker preamp is reduced according to the adjusted value. At this time, the Kth audio acquisition device is successfully debugged. The method for debugging audio collection equipment proposed by the present invention can achieve the global optimal effect through single debugging, can reduce debugging time, improve work efficiency, have high debugging accuracy, and can also reduce the experience requirements for debugging staff .

Description

technical field [0001] The invention relates to a method and device for debugging audio collection equipment. Background technique [0002] Before the meeting, it is usually necessary to manually debug the audio collection equipment (such as the microphone) in the conference system, so that the volume of the output sound meets the requirements of the meeting, and at the same time, there will be no howling; nowadays, it is usually performed by the staff based on their experience. Only repeated adjustments can meet its requirements, and there are disadvantages of slow debugging speed and low debugging accuracy, and the staff who carry out debugging at the same time need certain experience. [0003] In summary, it is necessary to further improve the prior art. Contents of the invention [0004] Aiming at the shortcomings in the prior art, the present invention provides a method for debugging audio collection equipment and a device for debugging audio collection equipment. ...
