Description
Technical field
The utility model belongs to multimedia transmission equipment technical field, is related to a kind of audio conversion separator.
Background technology
Audio frequency apparatus input is applied to each occasion, and with the continuous improvement of technical merit, people start to carry out audio
Processing, optimization, therefore audio separator by production application in field of audio processing, particularly in recording sites such as meeting, law courts
Application it is especially extensive, the audio separator on existing market due to relatively simple for structure, collecting audio carry out modulus turn
When changing, because sample frequency is not high enough, aliasing occurs for digital audio and video signals, can cause the phenomenon of audio distortions, simultaneously as existing
Some audio converters all realize the connection with equipment using HDMI mostly, when needing to access microphone, often through
Translation interface carries out transition, uses unusual inconvenience.
The content of the invention
The purpose of this utility model is to be directed to the above-mentioned problems in the prior art, there is provided a kind of easy to connect, quilt
The audio conversion separator of the audio sound clarity of separation.
The purpose of this utility model can be realized by following technical proposal：A kind of audio changes separator, including body
Be arranged at intrinsic mainboard, it is characterised in that be provided with power module on described mainboard, the sound being connected with power module
Frequency process chip, if be additionally provided with described mainboard be connected respectively with audio processing chip several DIN input interfaces,
Dry HDMI output interface, several XLR output interfaces, a DAC digital-to-analogue conversions module and a noise reduction processing
Module.
In a kind of above-mentioned audio conversion separator, described DIN input interfaces are to be available for external microphone to be directly connected to
Eight core ports, described HDMI output interface is connected by HDMI connecting lines with external computer main frame, and described XLR outputs connect
Mouth is connected by XLR balanced lines with the stereo set of outside.
In a kind of above-mentioned audio conversion separator, described DIN input interfaces, HDMI output interface and XLR outputs
Interface is respectively positioned on the outside portion of mainboard.
Compared with prior art, this audio conversion separator has the advantage that：
1st, noise reduction processing module is integrated with mainboard so that the sound of output can become apparent from.
2nd, the DIN input interfaces of eight cores are directly integrated and be attached on mainboard, avoid external conversion equipment, make its application
The wider model of scene, connection are more convenient.
Brief description of the drawings
Fig. 1 is the dimensional structure diagram of this audio conversion separator.
Fig. 2 is the schematic diagram of mainboard in this audio conversion separator.
Fig. 3 is the circuit block diagram of this audio conversion separator.
In figure, 1, body；2nd, mainboard；3rd, power module；4th, audio processing chip；5th, DIN input interfaces；6th, HDMI is exported

Embodiment
It is specific embodiment of the utility model and with reference to accompanying drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these embodiments.
As shown in Figure 1, Figure 2, Figure 3 shows, this audio conversion separator includes body 1 and the mainboard 2 being arranged in body 1, main
Power module 3 is provided with plate 2, the audio processing chip 4 being connected with power module 3, be additionally provided with mainboard 2 respectively with audio
Several DIN input interfaces 5 that process chip 4 is connected, several HDMI output interfaces 6, several XLR output interfaces 7, one
Individual DAC digital-to-analogue conversions module 8 and a noise reduction processing module 9, DIN input interfaces 5, HDMI output interface 6 and XLR
Output interface 7 is respectively positioned on the outside portion of mainboard 2, and exposes and be connected outside body 1 for external equipment, and wherein DIN input interfaces 5 use
The ports of eight cores.
When in use, microphone is inserted directly into DIN input interfaces 5 by connecting line, HDMI output interface 6 passes through
HDMI connecting lines are connected with external computer main frame, and XLR output interfaces 7 are connected by XLR balanced lines with the stereo set of outside.
The effect of wherein audio processing chip 4 is the transmission of control signal.The audio of microphone input passes through DIN input interfaces
5 transmit to noise reduction processing module 9, and noise reduction processing module 9 carries out noise reduction process to the audio of input, the sound after noise reduction
Frequency is transmitted separately to HDMI output interface 6 and DAC digital-to-analogue conversions module 8.The audio transmitted to HDMI output interface 6 is direct
It is transferred in the sound card of host computer, achieves and analyze for the later stage；Transmit to the audio quilt of DAC digital-to-analogue conversions module 8
Analogue audio frequency is converted into, is transmitted to stereo set and played by XLR output interfaces 7.
Specific embodiment described herein is only to the utility model spirit explanation for example.The utility model institute
Category those skilled in the art can make various modifications or supplement to described specific embodiment or using similar
Mode substitute, but without departing from spirit of the present utility model or surmount scope defined in appended claims.
Although body 1, mainboard 2, power module 3, audio processing chip 4, DIN input interfaces have more been used herein
5th, the term such as HDMI output interface 6, XLR output interfaces 7, DAC digital-to-analogue conversions module 8, noise reduction processing module 9,
But it is not precluded from the possibility using other terms.It is used for the purpose of more easily describing and explaining this practicality using these terms
New essence；Any additional limitation is construed as all to disagree with the utility model spirit.
