Problems solved by technology

Under normal circumstances, this wiring method is a simple and effective way to implement, but there are also shortcomings. The typical problem is that when the speaker forgets to press the microphone button, the voice of the speaker cannot be collected, and all subsequent sound effect processing will also be difficult. won't work

Embodiment 1

[0059] The working method of the conference room dual-control pickup system of the present embodiment includes:

[0060] Before the meeting starts, the microphone is turned off, at this time switch a is switched to its first movable end 1, and switch b is switched to its second movable end 4;

[0061] When the microphone is collecting sound, if switch b is switched to its first movable end 3, at this time, switch b, signal line 1, switch a, mixer power supply and reference level line form a loop, and the microphone works normally and collect sound;

[0062] When the microphone is collecting sound, if the state of switch b remains unchanged, switch a to its second active end 2. At this time, switch a, signal line 2, switch b, reference level line and mixer The power supply forms a loop, and the microphone works normally and collects the sound.

[0063] Specifically, when the microphone is collecting sound, if the state of the switch b remains unchanged, switch the switch a to...

Embodiment 2

[0065] The working method of the conference room dual-control pickup system of the present embodiment includes:

[0066] Step (1): Before the meeting starts, turn off the microphone, at this time switch a is connected with its first movable end 1, and switch b is connected with its second movable end 4;

[0067] Step (2): After the meeting starts, monitor the indicator light of the mixer in real time;

[0068] Step (3): When the speaker presses the button to speak, the switch b is connected to the first movable end 3 at this time, the circuit forms a loop, the indicator light of the mixer is on, the microphone works normally, and the sound can be collected; If the indicator light of the sound station is off, it means that the speaker has not pressed the button, and then proceed to the next step;

[0069] Step (4): Press the button of the mixer, at this time the switch a is connected to the second movable end 2, the circuit forms a loop, the indicator light of the mixer is on,...

Embodiment 3

[0072] The difference from the second embodiment is that a buzzer is connected in series between the fixed end of the switch a and the power supply of the mixer, and the buzzer is used to represent the working state of the microphone.

Abstract

The invention discloses a dual-control pickup system for a conference room and a working method thereof. The dual-control pickup system for the conference room comprises a first switch and a second switch, wherein the first switch is disposed on the mixer; the second switch is disposed on the microphone; the fixed end of the first switch is connected to the power supply of the mixer; the power supply of the mixer is connected to the fixed end of the second switch through the reference level line; the first switch and the second switch are respectively switched between the corresponding first active end and the second active end; the first active end of the first switch is connected to the first active end of the second switch through the first signal line; and the second active end of thefirst switch is connected to the second active end of the second switch through the second signal line. The invention is capable of effectively solving the pickup problem of the microphone when the switch is not switched, and ensuring the smooth progress of the conference.

Description

technical field [0001] The invention belongs to the field of sound pickup control, and in particular relates to a conference room dual-control sound pickup system and a working method thereof. Background technique [0002] Microphone equipment is an important part of the conference room audio system, which plays a role in collecting the sound of the venue. The reliability of the microphone equipment directly determines the reliability of the sound of the entire conference system. The traditional microphone wiring method is to place a microphone in the venue, connect it to the background mixer through an audio cable, and then send it to the speakers and other equipment in the venue through the mixer. The microphone itself has a button, and the corresponding port of the mixer also has a mute button. The sound input of the microphone can be controlled on and off. Under normal circumstances, this wiring method is a simple and effective way to implement, but there are also short...
