Abstract
The invention provides an audio-frequency USB key with multiple earphone interfaces and belongs to the mobile payment field. The USB key comprises earphone interfaces, an audio-frequency decoding circuit, an audio-frequency coding circuit and an encryption and decryption/storage circuit. The left channels L or right channels R in the earphone interfaces are employed as outputs of audio-frequency signals of a cellphone, and the audio-frequency decoding circuit decodes the audio-frequency signals. Grounds G are connected with the ground wires of the audio-frequency USB key. The data are subjected to audio-frequency coding by the audio-frequency coding circuit codes and input into microphone inputs M. The encryption and decryption/storage circuit is connected with the audio-frequency decoding circuit and the audio-frequency coding circuit respectively. The number of the earphone interfaces is 2 or more. The line sequences and sizes of each earphone interface are different. The left channels L, the right channels R, the grounds G and the microphone inputs M of each earphone interface are connected in one-to-one correspondence. The audio-frequency USB key can provide multiple earphone interfaces at the same time, so different earphone line sequences can be adapted and different earphone jack sizes can be met. The audio-frequency USB key has advantages of convenient usage and wide range of application.
Description
Technical field
The invention belongs to mobile payment field, particularly the audio intelligent cipher key of plurality of earphone interface.
Background technology
At present; Web bank generally adopts intelligent code key (USB KEY) to protect user's trading activity; because cipher key adopts multiple encryption algorithms and software and hardware security mechanism; therefore hacker and bogusware are difficult to the internal data of cipher key and password to steal; in process of exchange, cipher key adopts enciphered data and bank's background system to carry out alternately; even if data are monitored, also cannot forge and crack, protected to a great extent user's safety.
But, for mobile payment field, because mobile phone terminal lacks main frame USB interface, so traditional intelligent code key is difficult to be widely applied.Now, occurred that a kind of earpiece audio interface by mobile phone carries out the novel intelligent cipher key that enciphered message is transmitted in communication, this intelligent code key is by becoming sound signal by Data Modulation, then the Mike of the earphone interface by mobile phone input sends the data to mobile phone, and mobile phone passes to intelligent code key by left and right acoustic channels by data.Because nearly all mobile phone all has audio interface, so this audio intelligent cipher key has obtained certain application.
, in actual applications, run into a problem: earphone jack size and the line order of a lot of mobile phones are inconsistent.Conventional stereophone line order comprises two kinds, L/R/M/G and L/R/G/M, and two kinds of line orders are adopted by different cell phone manufacturers respectively.The size of earphone jack is also not quite similar, as 3.5mm and 2.5mm etc.
Audio intelligent cipher key of the prior art, generally only supports a kind of line order, a kind of size, and as shown in Figure 1, this mobile phone for not collinear order or size need to provide different intelligent code keys.In the sale and service process of intelligent code key, need to select applicable audio intelligent cipher key according to type that client provides, increased the complexity of selling and serving.In addition, if user in use need to change mobile phone, intelligent code key also will synchronously be changed so, has increased client's cost, also affects using and promoting of audio frequency cipher key.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the object of this invention is to provide a kind of audio intelligent cipher key of plurality of earphone interface.It can provide a plurality of earphone interfaces simultaneously, to adapt to different earphone cord orders and to meet different earphone jack sizes, has feature easy to use, applied widely.
In order to reach foregoing invention object, technical scheme of the present invention realizes as follows:
An audio intelligent cipher key for plurality of earphone interface, it comprises earphone interface, audio decoding circuit, audio coding circuit and encryption and decryption/memory circuit.In earphone interface, be equipped with L channel L, R channel R, G and Mike input M.L channel L or R channel R are as the sound signal output of mobile phone, and audio decoding circuit is decoded to this sound signal, recovers its data; Ground G is connected with the ground wire of audio intelligent cipher key; Audio coding circuit carries out audio coding and is input to Mike inputting M to data.Encryption and decryption/memory circuit interconnects with audio decoding circuit and audio coding circuit respectively.Its design feature is, the quantity of described earphone interface is two or more, and line order or the size of each earphone interface are not identical.L channel L between each earphone interface, R channel R, G and Mike input M respectively one by one correspondence be connected.
The present invention is owing to having adopted said structure, and a plurality of earphone interfaces can adapt to the demand of various mobile phone terminals, facilitates user to select as required suitable earphone cord order and earphone interface size.The present invention has feature easy to use, applied widely.
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art sound intermediate frequency intelligent code key;
Fig. 2 is the structural representation of the embodiment of the present invention.
Embodiment
Referring to Fig. 2, the present invention includes two or more earphone interface 4, audio decoding circuit 1, audio coding circuit 2 and encryption and decryption/memory circuit 3.4 li of earphone interfaces be equipped with L channel L, R channel R, G and Mike input M, line order or the size of each earphone interface 4 are not identical, but L channel L, R channel R between each earphone interface 4, G and Mike input M respectively one by one correspondence be connected.The L channel L that each earphone interface is 4 li is not used; Use R channel R as the sound signal output of mobile phone, 1 pair of this sound signal of audio decoding circuit is decoded, and recovers its data; Ground G is connected with the ground wire of audio intelligent cipher key; 2 pairs of data of audio coding circuit carry out audio coding and are input to Mike inputting M.Encryption and decryption/memory circuit 3 interconnects with audio decoding circuit 1 and audio coding circuit 2 respectively.
In the embodiment of Fig. 2, only provided two earphone interfaces, it is can use on the mobile phone terminal of L/R/M/G and L/R/G/M in earphone cord order.
The R channel R that in the example of Fig. 2, each earphone interface 4 is used, is not used L channel, when actual realization, can use L channel L yet.
The above; it is only a kind of example of the specific embodiment of the present invention; but protection scope of the present invention is not limited to this; allly be familiar with these those skilled in the art in technical scope disclosed by the invention; according to the apparent conversion of technical thought of the present invention or replacement, all should be encompassed in protection scope of the present invention.
