Embodiment one
As shown in Figure 1, providing a kind of live streaming microphone A100 of the embodiment of the present invention, comprising:
Microphone module A101, for picking up the first sound；
Microphone module A101 includes microphone to monitor and pick up the first sound；
Microphone also known as miaow core, microphone, microphone, microphone are the energy converters that voice signal is converted to electric signal
Part is a device (energy conversion device that converts electrical signals to voice signal) exactly the opposite with loudspeaker.Both are all
It is two terminals of sound device, microphone is input, and loudspeaker are output.
Noise reduction module A102 connects microphone module A101, for carrying out noise reduction process to the first sound to obtain second
Sound；
Noise reduction module A102 includes A/D chip to carry out noise reduction process to the first sound to obtain second sound.
A/D chip is to carry out the chip of analog-to-digital conversion conversion, is specifically analog signal to be converted into digital letter
Number.
The basic principle and feature of the AD of common several types is as follows:
1. integral form (such as TLC7135).Integrated AD working principle is that input voltage is converted into time (pulse width letter
Number) or frequency (pulse frequency), digital value is then obtained by timer/counter.Its advantage is that can be obtained with ball bearing made
High-resolution, but the disadvantage is that conversion rate is extremely low since conversion accuracy depends on the time of integration.The monolithic AD conversion at initial stage
Device mostly uses greatly integral form, and gradually compare type now gradually becomes mainstream.
2. gradually comparing type (such as TLC0831).Gradually comparison A/D is by a comparator and DA converter by gradually comparing
Compared with logical constitution, since MSB, sequentially input voltage and the output of built-in D/A converter are compared by each, through n times
Compare and exports digital value.Its circuit scale belongs to medium.Its advantage is that speed is higher, low in energy consumption, low resolution (< 12)
When it is cheap, but high-precision (> 12) when price it is very high.
3. type (such as TLC5510) is compared in relatively type/serial parallel parallel.Parallel comparison A/D uses multiple comparators, only makees
It is primary relatively to carry out conversion, also known as FLash (quick) type.Since conversion rate is high, n conversions need 2n-1 comparison
Device, therefore circuit scale is also very big, price is also high, is only applicable to the extra high field of video AD converter uniform velocity.Serial parallel
Between parallel and gradually compare between type in comparison A/D structure, most typically by 2 n/2 parallel converters
Cooperate D/A converter composition, carry out conversion with comparing twice, so referred to as Half flash (half quickly) type.Also it is divided into three steps
Or multistep realizes that AD conversion is called classification (Multistep/Subrangling) type AD, and can claim from conversion timing sequence angle
For assembly line (Pipelined) type AD, it is also added into modern classification-type AD and digital operation is made to multiple conversions result and is repaired
The functions such as positive characteristic.This kind of AD speed ratio gradually compares type height, and circuit scale is smaller than parallel.
Sigma-delta 4. (Sigma/FONT > delta) modulation type (such as AD7705).Sigma-delta type AD is by integrator, comparator, 1
The position composition such as D/A converter and digital filter.It is similar to integral form in principle, input voltage is converted into the time, and (pulse is wide
Degree) signal, digital value is obtained after being handled with digital filter.The numerical portion of circuit is substantially easy singualtion, therefore is easy
Accomplish high-resolution.It is mainly used for audio and measurement.
5. capacitor array gradually compares type.Gradually comparison A/D uses capacitance matrix to capacitor array in built-in D/A converter
Mode, alternatively referred to as Charge scaling type.The value of most resistance must be consistent in general electric resistance array D/A converter, in single
On piece generates high-precision resistance and is not easy to.If replacing electric resistance array with capacitor array, height can be made with low cost
Precision monolithic converter.Nearest successive comparison type AD converter is mostly capacitor array type.
6. voltage to frequency conversion type (such as AD650).Voltage to frequency conversion type (Voltage-Frequency Converter) is to pass through
Indirect conversion mode realizes analog-to-digital conversion.Its principle is that the analog signal of input is converted into frequency first, then with counting
Device is by frequency conversion at digital quantity.Theoretically the resolution ratio of this AD almost can infinitely increase, as long as the time of sampling
It can satisfy the width of the pile-up pulse number of output frequency resolution ratio requirement.Its advantage is that high resolution, low in energy consumption, price
It is low, but external counting circuit is needed to complete AD conversion jointly.
