Embodiment
Main design of the present invention is: the loud speaker that utilizes portable terminal (for example mobile phone) generally to have, the magnetic signal that produces by loud speaker is that carrier carries out the information transmission.Exactly, be that the leakage field that utilizes the loud speaker of portable terminal to produce when sounding carries out the information transmission.
Below in conjunction with accompanying drawing principle of the present invention and feature are described, institute gives an actual example and only is used for explaining the present invention, is not for limiting scope of the present invention.
Fig. 1 is the flow chart of information transferring method in the embodiment of the invention.As shown in Figure 1, in the present embodiment, the flow process of information transferring method comprises:
Data to be transmitted information can be short message data, voice data, Still image data etc.
The data to be transmitted information translation is that magnetic field data mainly comprises following process:
(a1) magnetic signal framing;
(a2) magnetic channel transfer encoding;
(a3) magnetic signal modulation.
In short, by magnetic signal framing, magnetic signal transfer encoding and modulation, namely generate magnetic field data.
Waveform after the magnetic field data modulation can be sawtooth waveforms, sine wave, impulse wave etc.The speed of magnetic field data modulation is 20Hz---20KHz.
Magnetic field data can be converted to voice data and store with the form of audio file.Audio file is easy to storage, and can play by various players, is easy to the interface operation on portable terminals such as mobile phone.
Be that the process of audio file is with the data to be transmitted information translation:
(b1) with the magnetic field data of above-mentioned generation as audio data sample, this audio data sample is quantized and encodes;
(b2) to quantize and coding after data operation such as can compress; This step is inessential step;
(b3) add file header, end-of-file in the signal after compression, and be stored as audio file according to the storage format of audio file, namely obtained audio file.
In short, magnetic field data is quantized and encode after store according to the storage format of audio file again and namely obtained audio file.
Audio file can be sound waveform file, third generation audio files compressed format etc.
What wherein, aforesaid coded system was the most basic is the natural binary coding mode.Especially, when data to be transmitted was converted to audio file, coded system can be pulse code modulation, differential pulse code modulation, adaptive differential pulse-code modulation, sub-band coding etc. usually.Pulse code modulation can be linear impulsive coded modulation or logarithm pulse code modulation.
In first processing procedure, data to be transmitted information can be made up according to certain frame format definition.Can be the frame of regular length with the data to be transmitted information combination, also can be combined as the frame of on-fixed length.For the frame of regular length, can earlier data to be transmitted information be divided into a plurality of, adopt the coded system that is adapted at transmitting in the magnetic channel to encode to different pieces.The Frame of being formed a regular length then by the sign of the data behind a plurality of codings and some identification frames.For the frame of on-fixed length, can encode and add identification code the data to be transmitted information of regular length.In being combined as the process of frame, the position of the identification code of frame can be fixed also and can not fix.For the frame of regular length, identification code can be placed on the beginning of a frame, also can be positioned at the center of a frame.For the frame of on-fixed length, identification code is placed on the beginning of a frame.The identification code of frame can be chosen as unique, also can be not exclusive, and to distinguish dissimilar frames.

When audio file passes through player plays, remove some file format information earlier, the operations such as (not necessarily) that decompresses again, sending into digital to analog converter after decoding is analog signal again, carry out power amplification again, drive electro-acoustic conversion devices such as loudspeaker at last.
So on the whole, data message waiting for transmission can be converted to magnetic field data, these data directly drive loudspeaker by hardware corridor; Or magnetic field data is converted to audio file again, drive loudspeaker in the mode of displaying audio file.This dual mode finally all is that the data that will transmit this carrier of leakage field during by sound horn transfers out.
Under the driving that drives signal, on the one hand, electro-acoustic conversion device produces the magnetic signal that comprises data message, by magnetic signal data message is sent; On the other hand, electro-acoustic conversion device also produces the voice signal that comprises data message, by voice signal data message is sent.
