The utility model can replace the existing special equipment, has the advantages of simplicity, low price, convenient use and the like, and can be instantly used after being inserted.
Description
Technical field
The utility model relates to the electronic product field, relates in particular to a kind of USB phone and USB headset based on mobile phone.
Background technology
In order to use VOIP (the Voice OVer IP) networking telephone more easily, such as Skype (a kind of widely used network telephone software), can realize better communication effect by USB phone or USB headset, use more conveniently simultaneously, meet the common conversation of people custom.Present mobile phone is all supported USB and camera basically, and most mobile phones are supported the USB camera function, are exactly that mobile phone connects PC by USB, can realize the USB camera use of the camera of mobile phone as PC, as the shooting instrument of Internet video chat.But microphone on the mobile phone and loudspeaker, keyboard are not utilized, connect by USB equally, based on the USB audio protocols can be to realize mobile phone as USB phone or USB headset, simultaneously based on USB HID (HumanInterface Device man-machine interaction agreement) agreement with the keyboard of cell phone keyboard as the USB phone.The utility model just is based on such technical background to realize USB phone or USB headset on mobile phone, has strengthened cell-phone function, makes carrying of USB phone and USB headset become more convenient.
Summary of the invention
At the deficiency of prior art, the purpose of this utility model is to provide a kind of USB phone or USB headset based on mobile phone, and mobile phone links to each other with computer by USB.
The utility model is achieved by the following technical solution:
A kind of USB phone or USB headset based on mobile phone, comprise mobile phone baseband, microphone, loudspeaker, A/D, USB, computer, the Internet, described mobile phone is connected with computer by USB, utilize the microphone of mobile phone itself and audio frequency output, input and the keypad function that loudspeaker, keypad function are realized computer, utilize the related protocol of USB, with audio amplifier, microphone and the keyboard equipment of mobile phone as computer.Adopted Windows audio frequency, the keypad protocol standard mode of standard to realize that computer-side need not to install and drives, and can accomplish plug and play.The sound that microphone collects is sampled as the pcm encoder voice data by the built-in A/D of mobile phone baseband processor (conversion of Analog/Digital analog signal figure), passes to computer by USB, is transferred to the Internet by the computer code compression again.
The voice data that computer is received from the Internet, the decompress(ion) of decoding is condensed to the PCM data, pass to mobile phone by USB, be converted to analog signal by the built-in D/A of mobile phone baseband processor (Digital/Analog digital signal analog-converted) and output to loudspeaker through amplifying.The utlity model has realize simple, cheap, easy to use can plug and play etc. advantage.

The number in the figure explanation
1-mobile phone baseband, 2-microphone, 3-loudspeaker, 4-A/D
5-USB, 6-computer, 7-the Internet
Embodiment
How further specify the utility model below in conjunction with accompanying drawing realizes:
Audio (audio frequency) agreement of utilizing USB can be based on the compatible USB1.1 version of USB2.0 as the host-host protocol between computer and the mobile phone.
Utilize the HID agreement of USB that cell phone keyboard is invented the USB keyboard, can realize basic functions such as digit dialling.
As shown in Figure 1, mobile phone is connected with computer 6 by USB interface 5, based on USB Audio agreement, the A of employing standard rule PCM (Pulse Code Modulation pulse code coded modulation) coding, i.e. ITU (International Telecommu nication Union International Telecommunications Union) standard G.711.The 1. flow process of Fig. 1, the sound that microphone 2 collects is sampled as the pcm encoder voice data by the built-in A/D4 of mobile phone baseband 1 processor (conversion of Analog/Digital analog signal figure), pass to computer 6 by USB, be transferred to the Internet 7 by the computer code compression again.
The 2. flow process of Fig. 1, the voice data that computer 6 is received from the Internet, the decompress(ion) of decoding is condensed to the PCM data, pass to mobile phone by USB interface 5, be converted to analog signal by the built-in D/A4 of mobile phone baseband 1 processor (Digital/Analog digital signal analog-converted) and output to loudspeaker 3 through amplifying.
