Abstract
The utility model provides an audio conference system, which structurally comprises an audio signal input end for inputting audio signals, a first operational amplifier for amplifying the audio signals, a second operational amplifier for converting alternating-current analogue signals into digital signals, and a main control chip for reading the signals. Compared with the prior art, the audio conference system has the characteristics of reasonable design, simple structure and good use convenience. The audio conference system provided by the utility model effectively solves the manual switching problem of a conference microphone, automatically switches on and off the microphone according to the speaking condition of a speaker, and greatly improves troubles resulted from the fact that conference participants are unfamiliar with devices or inconvenient to carry out manual operation.
Description
Technical field
The utility model relates to field of intelligent control technology, specifically a kind of speech conference system of opening and closing automatically realized.
Background technology
Existing conference system, mainly comprise conference microphone and conference host, conference microphone when in use, all need the manual speech button of pressing, just can open the public address function, make a speech complete after, need the speech button that clicks again initiatively to close microphone, have sometimes that the participant does not know out microphone or the complete situation of closing microphone of forgetting of making a speech, brought certain impact for the process of meeting, this just is unfamiliar with the puzzlement that equipment or inconvenient manually operated participant bring.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of simple in structure, speech conference system is provided.
The technical solution of the utility model realizes in the following manner, the first transport and placing device that this a kind of speech conference system, its structure comprise the audio signal input end of input speech signal, amplify audio signal, convert the AC analogue signal to the second transport and placing device of digital signal, the main control chip of read signal.
As preferably, described audio signal input end refers to microphone.
As preferably, be provided with the reshaping device that AC signal is made into direct current signal between described the first transport and placing device and the second transport and placing device.
As preferably, described reshaping device is constituted by a diode.
In sum, the beneficial effect that compared with prior art produces of the utility model is:
That a kind of speech conference system of the present utility model has is simple in structure, be skillfully constructed, the characteristics such as reasonable in design, this speech conference system is realized Based Intelligent Control, in use fully without any need for manual operation, just can finish smoothly whole conference speech, the meeting keeper from using the work of microphone, loaded down with trivial details training participant is freed, simultaneously, and the application of voice-activated function, greatly reduce the frequency of utilization of mechanical key, improve the useful life of whole voice system.
Description of drawings
Accompanying drawing 1 is structured flowchart of the present utility model.
Mark in the accompanying drawing represents respectively:
1, audio signal input end, the 2, first transport and placing device, 3, diode, the 4, second transport and placing device, 5, main control chip.
Embodiment
Below in conjunction with accompanying drawing a kind of speech conference system of the present utility model is described in detail below.
As shown in Figure 1, the first transport and placing device 2 that this a kind of speech conference system, its structure comprise the audio signal input end 1 of input speech signal, amplify audio signal, convert the AC analogue signal to the second transport and placing device 4 of digital signal, the main control chip 5 of read signal.The MIC voice signal is that audio signal is amplified through first order amplifier, and second level amplifier is again the level conversion of square-wave signal to be become Transistor-Transistor Logic level after the audio signal of amplifying is converted to the square wave that can reflect the audio signal size, reads for main control chip 5.
Described audio signal input end 1 refers to microphone.
Be provided with the reshaping device that AC signal is made into direct current signal between described the first transport and placing device 2 and the second transport and placing device 4; Described reshaping device is comprised of diode 3.
When conference host is adjusted to the voice-activated pattern, all conference microphones will be according to spokesman's speech situation and the automatic switch microphone, when people's on-mike and speech are arranged, conference microphone can be opened automatically, sound is sent to sound reinforcement system, after speech finishes or after interrupting 3～5 seconds midway, conference microphone meeting autoshutdown, perhaps non-speech content sends in some secrets with the spokesman to avoid.In addition, according to the use habit of different user, the sensitivity that microphone opens and closes automatically is adjustable, and when spokesman's voice intensity reached the threshold values of microphone setting, microphone just can be opened.
Should be noted that at last; above content is only in order to illustrate the technical solution of the utility model; but not to the restriction of the utility model protection range; although this embodiment part has been done to explain to the utility model; those of ordinary skill in the art is to be understood that; can make amendment or be equal to replacement the technical solution of the utility model, not break away from essence and the scope of technical solutions of the utility model.
