Abstract
This utility model embodiment discloses a kind of structure for mobile phone charge port transmission voice data, including OTG adapter and operational amplifier, it is connected by D/A change-over circuit between described OTG adapter and described operational amplifier, described operational amplifier is at least connected with a speaker, and described OTG adapter at least includes a Micro USB male joint connected with mobile phone charging USB interface.The beneficial effects of the utility model are: a kind of structure for mobile phone charge port transmission voice data that this utility model provides, by the layout of structure, realize mobile phone charging port transmission voice data, i.e. maintain the original function of charging port, port versatility is provided, and then improves adnexa portability；Make full use of this port simultaneously and realize voice data transmission, and be prevented effectively from the quality distortion of audio signal by this kind of structure.
Description
Technical field
This utility model relates to voice data transmission structure, particularly a kind of for mobile phone charge port transmission audio frequency
The structure of data.
Background technology
Along with the development of the Internet science and technology, mobile electronic product is more and more universal, especially this daily as mobile phone
Communication equipment, has become as indispensable instrument in life, people to the intellectuality of mobile phone, personalized with
And practicality proposes requirements at the higher level, but current mobile phone charge data port is generally not capable of with earphone mouth
With, say, that directly audio frequency can not be play adnexa and directly be play by charge data port, very the biggest
Limit mobile phone just uses property, and needs to connect different adnexa when using and realize respective performance, extremely inconvenience.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that one for mobile phone charge oral instructions
The structure of defeated voice data, by the layout of structure, it is achieved mobile phone charging port transmission voice data,
I.e. maintain the original function of charging port, it is provided that port versatility, and then improve adnexa portability；Simultaneously
Make full use of this port and realize voice data transmission, and be prevented effectively from the sound of audio signal by this kind of structure
Matter distortion.
In order to solve above-mentioned technical problem, the one that this utility model embodiment provides transmits sound for mobile phone charge port
The structure of frequency evidence, it thes improvement is that: include OTG adapter and operational amplifier, described OTG
Being connected by D/A change-over circuit between adapter with described operational amplifier, described operational amplifier at least connects
A speaker, described OTG adapter is had at least to include a Micro USB connected with mobile phone charging USB interface
Male.
In said structure, described operational amplifier is power amplifier, described power amplifier and described Micro USB
Power supply wiring foot and the low level wiring pin of male are electrical connected.
In said structure, described Micro USB male joint includes an ID pin being connected with described low level wiring pin.
Implement this utility model embodiment, have the advantages that
In this utility model embodiment, the one that this utility model provides transmits audio frequency number for mobile phone charge port
According to structure, by the layout of structure, it is achieved mobile phone charging port transmission voice data, i.e. maintain
The original function of charging port, it is provided that port versatility, and then improve adnexa portability；Make full use of simultaneously
This port realizes voice data transmission, and is prevented effectively from the quality distortion of audio signal by this kind of structure.
Accompanying drawing explanation
Fig. 1 is a kind of structured flowchart for mobile phone charge port transmission voice data in this utility model embodiment.
Detailed description of the invention
Below in conjunction with the accompanying drawings and this utility model is further described by detailed description of the invention:
With reference to Fig. 1, this utility model discloses a kind of structure for mobile phone charge port transmission voice data, bag
Include OTG adapter 2 and operational amplifier 4, between OTG adapter 2 and operational amplifier 4, pass through D/A
Change-over circuit 3 is connected, and operational amplifier is at least connected with a speaker 5, and OTG adapter 2 at least includes one
The Micro USB male joint connected with mobile phone charging usb 1, it will of course be understood that, put in computing
It is provided with level setting switches greatly, in order in use between device 4 and speaker 5, on the basis of keeping primary sound,
Strengthen user's control to volume.
Further, operational amplifier 4 is power amplifier, power amplifier and Micro USB male joint
Power supply wiring foot and low level wiring pin are electrical connected, and so can detect the transmitting terminal of place's audio signal, from
And the directive sending of beneficially audio signal.
Further, Micro USB male joint includes an ID pin being connected with low level wiring pin.
Described above is only preferred embodiment of the present utility model, and above-mentioned specific embodiment is not to this reality
With novel restriction.In technological thought category of the present utility model, various deformation and amendment can occur,
Retouching, amendment or the equivalent that all those of ordinary skill in the art are made as described above, belongs to
The scope that this utility model is protected.
