Abstract
The utility model discloses a mobile phone realizing data interaction through a microphone and a loudspeaker. The mobile phone comprises a base band chip, a coding module, the loudspeaker, the microphone and a decoding module which are arranged in a mobile phone body, wherein the coding module is respectively connected with the base band chip and the loudspeaker, the coding module is respectively connected with the base band chip and the loudspeaker, and the decoding module is respectively connected with the base band chip and the microphone. The mobile phone realizing data interaction through the microphone and the loudspeaker adopts the technical scheme that the microphone and the loudspeaker arranged on the mobile phone can be used for carrying out data transmission, so the cost is reduced, but the same mutual data transmission effect between the mobile phones is reached.
Description
Technical field
The utility model relates to cell phone apparatus, particularly a kind of mobile phone by microphone and loud speaker interaction data.
Background technology
Two kinds nothing but of transfer of data between general mobile phone: the data transfer mode that depends on operator: as, phone, note.Another is to utilize the mobile phone device to carry out transfer of data, as, utilize bluetooth, WIFI, mode such as infrared.First kind scheme can produce communication cost, and second kind owing to needing to add extra device, so the cost of mobile phone is increased.
Transfer of data, in transfer of data, the processing of bottom must be that transformation of data is propagated for the most basic binary form.It the most also is the unique data mode that can " discern " that binary system is only computer (or other electronic products).As, an English alphabet is preserved as using ASCII, and he can take a byte so, just 8 binary systems.ASCII character as " h " is 104, and being converted into binary system then is 01101000; Audio frequency and binary digital-to-analogue conversion, in the binary system owing to have only 0 and 1, so usually can with mutual mapping such as closing of circuit in the reality, disconnection.For audio frequency, can be with quiet representative 0, sound represents 1.
In view of this, those skilled in the art provide a kind of mobile phone by microphone and loud speaker interaction data at the problems referred to above.
The utility model content
The utility model provides a kind of mobile phone by microphone and loud speaker interaction data, overcome the difficulty of prior art, the scheme that can utilize receiver that mobile phone carries and loud speaker to carry out transfer of data, thus but cost squeeze reach equally makes between the mobile phone effect of transmission data mutually.
The utility model adopts following technical scheme:
The utility model provides a kind of mobile phone by microphone and loud speaker interaction data, comprises the baseband chip, coding module, loud speaker, microphone and the decoder module that are arranged in the mobile phone body;
Described coding module connects described baseband chip and loud speaker respectively, and described decoder module connects described baseband chip and microphone respectively.
Preferably, described mobile phone body is a bar phone.
Preferably, described mobile phone body is a clamshell phone.
Preferably, described mobile phone body is a smart mobile phone.
Preferably, described mobile phone body is a game mobile phone.
Preferably, described mobile phone body is a multimedia handset.
Owing to adopted above-mentioned technology, compared with prior art, the scheme that mobile phone by microphone and loud speaker interaction data of the present utility model can utilize receiver that mobile phone carries and loud speaker to carry out transfer of data, thus but cost squeeze reach equally makes between the mobile phone effect of transmission data mutually.
Further specify the utility model below in conjunction with drawings and Examples.

Embodiment
Introduce a kind of specific embodiment of the present utility model below by Fig. 1 and 2.
Embodiment 1
As shown in Figure 1, a kind of mobile phone by microphone and loud speaker interaction data of the present utility model comprises the baseband chip, coding module, loud speaker, microphone and the decoder module that are arranged in the mobile phone body; Described coding module connects described baseband chip and loud speaker respectively, and described decoder module connects described baseband chip and microphone respectively.
Described mobile phone body is a bar phone, or clamshell phone, or smart mobile phone, or game mobile phone, or multimedia handset.
The actual operating position of the mobile phone by microphone and loud speaker interaction data of the present utility model is as follows:
The utility model carries out digital-to-analogue conversion to the data that needs send, and data is become make the recipient sense after audio frequency changes.The recipient carries out the one-off pattern number conversion again, with Data Receiving.By this process, make the data that send on the mobile phone can be sent on the another one mobile phone.
Crucial part of the present utility model is the digital-to-analogue conversion between audio frequency and the binary data.Both sides need arrange a time interval.Can send the unit that an audio frequency changes as per 50 milliseconds.
Connecting the example of literary composition, as shown in Figure 2, is 104 as the ASCII character of English " h ", and the content of its actual storage on mobile phone is a Binary Zero 1101000 so.By to binary digital-to-analogue conversion (with quiet performance 0, sound performance 1), can obtain one section special audio volume control (if audio frequency transmission here is 50 milliseconds at interval, beginning has 50 milliseconds quiet so, be 100 milliseconds sound subsequently, being again the sound of 50 milliseconds quiet and 50 milliseconds afterwards, is 150 milliseconds quiet at last).By this audio frequency of loudspeaker plays, recipient's mobile phone carries out analog-to-digital conversion again can be with reduction of data.Analog-to-digital process is as follows.
As shown in Figure 3, then represent to receive 1 when the microphone that puts the cell phone when reception receives sound, otherwise be 0.Binary system assembly unit preservation then can be reduced to the letter " h " that the transmit leg mobile phone is sent.
In order to reduce the noise jamming of process of transmitting, can select the insensitive sound frequency of human auditory to the user., between 20-20000Hz, be used to transmit data frequency so and can select to be lower than 20HZ or to be higher than 20000HZ as human ear's audibility range.
In order to improve the antijamming capability of transmission course, can set an audiorange, can think down quietly as certain decibel, think generation more than certain decibel.Thereby avoid the external interference in the transport process as far as possible.Also can add some data check modes for data, as simple parity check or method that some are more complicated.
In order to make the recipient know the start and end time that audio frequency transmits, we also can define beginning and end that two more special audio frequencies are used to identify transmission course.
For example:
(1) the A mobile phone need send to electronic business card of B mobile phone.
(2) A mobile phone and B mobile phone switch to the audio transmission pattern.The microphone of B is near the loud speaker of A mobile phone.
(3) the handset-selected electronic business card of A sends according to the audio transmission pattern, and the B mobile phone is received voice data and is stored to mobile phone this time.
(4) transmission course is finished.
In summary, owing to adopted above-mentioned technology, the scheme that mobile phone by microphone and loud speaker interaction data of the present utility model can utilize receiver that mobile phone carries and loud speaker to carry out transfer of data, thus but cost squeeze reach equally makes between the mobile phone effect of transmission data mutually.
Above-described embodiment only is used to illustrate technological thought of the present utility model and characteristics, its purpose is to make those skilled in the art can understand content of the present utility model and implements according to this, can not only limit claim of the present utility model with present embodiment, be all equal variation or modifications of doing according to the spirit that the utility model disclosed, still drop in the claim of the present utility model.
