Various terminal equipments are in short distance during with wireless mode transmission information in the prior art, need terminal equipment to possess independently hardware module and support employed short range wireless transmission technology, cause in short distance the cost of transmitting information wirelessly higher.To this problem, the embodiment of the invention has proposed to carry out in short distance with sound wave the scheme of message transmission.
The flow chart of the method for sending information that Fig. 1 provides for one embodiment of the invention.As shown in Figure 1, the method for present embodiment comprises:
Usually; Terminal equipment all has audio frequency output module, audio frequency receiver module, modulation module and demodulation module etc.; These modules are used for accomplishing voice signal (in various embodiments of the present invention; Can be called voice signal by the acoustic signals that people's ear is heard) reception and transmission; Wherein, the frequency of normal sound signal is 20-20KHz.
Present embodiment utilizes the modulation module of terminal equipment, and digital signal information to be sent is corresponding according to preset modulating frequency is modulated to acoustic signals.Wherein, preset modulating frequency can be greater than 20KHz, and the acoustic signals that then modulates is a ultrasonic signal, and after promptly this acoustic signals was exported by the audio frequency output module, extraneous personnel can't hear; In addition, preset modulating frequency also can be greater than 20Hz less than 20KHz, and the acoustic signals that then modulates is a voice signal, and after promptly this acoustic signals was exported by the audio frequency output module, extraneous personnel can hear.
Terminal equipment in the present embodiment can be various equipment with audio signal sending function, for example: mobile phone, personal digital assistant (Personal Digital Assistant; Abbreviate as: PDA), panel computer, portable personal computer (Personal Computer such as IPad; Abbreviate as: PC), point-of-sale terminal (Point Of Sale; Abbreviate as: POS) machine etc., and the audio frequency output module of terminal equipment can be Mike, loudspeaker etc.
In the practical implementation process, when terminal equipment has information to send, at first information to be sent is handled through the transmission processing module of terminal equipment, generate digital signal, be meant that mainly with information translation to be sent be digital signal.Then; Send processing module digital signal is sent to modulation module; By modulation module according to pre-set modulating frequency; Digital signal is modulated, with digital signal be modulated to acoustic signals (for example: frequency greater than the ultrasonic signal of 20KHz or frequency at 20Hz to the voice signal between the 20KHz).Then, modulation module offers the audio frequency output module with the acoustic signals that modulates.
Wherein, The information that terminal equipment need send has multiple source, and for example: the user is the short message content of input manually, the various jokes that terminal equipment is downloaded from webpage, news etc.; Can also be the various information that are stored in advance on the terminal equipment, for example: the password of miscellaneous service, user name etc.Wherein, because of the information of transmission to be sent is different, the mode of obtaining information to be sent is also different.
In this explanation, present embodiment is not done qualification to the employed modulation system of modulation module, for example: can use amplitude-shift keying (Amplitude Shift Keying; Abbreviate as: ASK) modulation system, frequency shift keying (Frequency-shift keying; Abbreviate as: FSK) modulation system etc.Wherein, the modulation principle and the implementation of modulation module are similar in the modulation principle of modulation module and implementation and the existing terminal equipment, so do not do detailed argumentation at this.
The audio frequency output module sends to receiving terminal with acoustic signals after receiving the acoustic signals that modulation module provides.Wherein, receiving terminal can be for having the various terminal equipments that receive acoustic signals, for example mobile phone, PDA, PC, POS machine etc.
The method for sending information of present embodiment; Terminal equipment is modulated to acoustic signals through its modulation module with digital signal; By its audio frequency output module acoustic signals is sent to receiving terminal then; Message transmission between realization and the receiving terminal; Compared with prior art, this enforcement does not need terminal equipment to increase the additional hardware module, has simplified the implementation structure of terminal equipment; Practice thrift the expense that terminal equipment is reequiped, and then reduced the required cost of message transmission.
Further, when present embodiment adopted ultrasonic wave that information is transmitted, the characteristics of utilizing ultrasonic signal to be heard by people's ear need not to worry leaking of information in the transmission course, and information is had certain confidentiality; Moreover, because people's ear can't hear ultrasonic wave, so with not producing noise in the process of ultrasonic transmission information.
The flow chart of the method for sending information that Fig. 2 provides for another embodiment of the present invention.As shown in Figure 2, the method for present embodiment comprises:
In the present embodiment, when terminal equipment will send information, trigger to send processing module and obtain information to be sent, and be digital signal information translation to be sent.
Send processing module and digital signal is encrypted, to improve the fail safe of message transmission according to the cryptographic algorithm of making an appointment.Then, the digital signal of sending after processing module will be encrypted sends to modulation module, triggers modulation module digital signal is modulated.Wherein, send processing module and can directly send the digital signal after encrypting to modulation module.In addition, send processing module and also can send notice message to modulation module earlier, prepare so that modulation module is carried out to receive, and then the digital signal after will encrypting sends to modulation module.
Wherein, preset modulating frequency can be greater than 20KHz, and the acoustic signals that then modulates is a ultrasonic signal.In addition, preset modulating frequency also can be greater than 20Hz less than 20KHz, and the acoustic signals that then modulates is a voice signal.
Concrete, modulation module receives the digital signal after encrypting, and then digital signal is carried out modulation treatment, obtains acoustic signals.Wherein, digital signal has been carried out encryption, so the waveform of the acoustic signals that present embodiment modulates is different with the waveform of middle acoustic signals embodiment illustrated in fig. 1 owing to send processing module in the present embodiment.
