Equipment.
Background technology
At present, the function such as the video playback of mobile phone, game, online, office is more and more stronger, especially smart mobile phone, can be with
By installing the various functions of various application software extended mobile phones, and mobile phone is limited by its own screen size, viewing film,
It is preferable not to the utmost to play game, online, office and other effects, this just needs the content shown by it being output to such as television set, projection
Instrument, computer monitor other display devices on, and when mobile phone is connected on other display devices by sound, video signal cable
When, operate just inconvenient.In the market pushes away screen equipment a bit, video can be pushed into display by USB interface and set
Standby upper display, but USB interface can not push audio.
Utility model content
In view of this, it is defeated to be to provide a kind of traditional USB interface voiceless sound of solution for the technical problems to be solved in the utility model
The equipment gone out, by wireless network by the audio video transmission on mobile device to display device, while export audio.
In order to solve the above-mentioned technical problem, the utility model employs following technical scheme.
A kind of equipment for solving traditional USB interface voiceless sound output, based on ARM frameworks and runs OpenWRT systems, including
CPU, power supply module, WIFI modules, signal conversion IC, 3.5mm COBBAIFs, USB interface；Described in the CPU inputs access
Power supply module, the WIFI modules, the CPU output ends access signal conversion IC, HDMI, the signal conversion IC output
Terminate into the 3.5mm COBBAIFs, USB interface；
Wherein, mobile device accesses what the traditional USB interface voiceless sound of solution exported by ANT antennas, WIFI modules
Equipment, the equipment for solving traditional USB interface voiceless sound output are connect by 3.5mm COBBAIFs, USB interface, HDMI
Enter display device；The mobile device includes mobile phone, tablet personal computer, notebook computer, and the display device includes TV, display
Screen, the projecting apparatus for being equipped with stereo set.
Further, including MCU, indicator lamp, the MCU inputs access the power supply module, described in output end access
Indicator lamp.
Further, including built-in power, the built-in power connect the power supply module, CPU, MCU respectively.
Beneficial effect：A kind of equipment for solving traditional USB interface voiceless sound output of the utility model, mobile device pass through
ANT antennas access this device, allow display device to play the audio frequency and video on mobile device, have an easy to operate, low-power consumption, it is low into
Originally, the advantages that easy exploiting；3.5mm interfaces+a variety of audio frequency and video output ports of USB interface/HDMI can access different type
Display device, extend the use range of this device.
Brief description of the drawings
Fig. 1 is the EM equipment module structured flowchart for solving traditional USB interface voiceless sound output.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
It should be noted that when element is referred to as " being fixed on " or " being arranged at " another element, it can be directly another
On one element or it may be simultaneously present centering elements.When an element is known as " being connected to " another element, it can
To be directly to another element or may be simultaneously present centering elements.
It should also be noted that, the orientation term such as left and right, upper and lower in the utility model embodiment, is only relative each other
Concept or using the normal operating condition of product as reference, and should not be regarded as restrictive.
Illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by embodiment.
Understand, a kind of equipment for solving traditional USB interface voiceless sound output, based on ARM frameworks and run as shown in Figure 1
OpenWRT systems, including the conversion of CPU, power supply module, WIFI modules, signal, 3.5mm COBBAIFs, USB interface；The CPU
Input accesses the power supply module, the WIFI modules, and the CPU output ends access signal conversion IC, HDMI are described
Signal conversion IC output end accesses the 3.5mm COBBAIFs, USB interface；Include modular converter on the CPU, for sound
Video format is changed；The power supply module is Micro USB charging inlets, is powered for device；The signal conversion IC carries out letter
Number digital-to-analogue conversion, can convert digital signals into analog signal；Due to USB interface and do not have audio frequency transmission function, therefore need
Coordinate 3.5mm COBBAIFs, could so play audio.The CPU inputs access power supply module, are to set by power supply module
Available electricity, the CPU inputs access WIFI modules, and mobile device audio frequency and video are inputted CPU by WIFI modules, and the CPU passes through
The HDMI of connection can be by audio/video pushing to display device.
Mobile device includes mobile phone, tablet personal computer, notebook computer, by being set described in ANT antennas, the access of WIFI modules
It is standby, audio, video data is transferred to by the CPU by the WIFI modules, audio, video data is changed by CPU modular converter
After form, through signal conversion IC, audio frequency and video are output to display device by HDMI includes the projecting apparatus of TV, outfit stereo set
Play out, signal conversion IC is converted to audiovisual digital signal after analog signal by 3.5mm COBBAIFs and USB interface
Projecting apparatus of the display device including TV, outfit stereo set is output to play out.
Further, including MCU, indicator lamp, the MCU inputs access the power supply module, described in output end access
