The display module includes mobile phone screen or palm PC or LCDs or can show result equipment.
Fig. 2 shows that its is detailed another object of the present invention is to provide a kind of flow chart of the implementation method of acoustic keyboard
State as follows：
Step S1, sound is tapped to each button on keyboard and carries out predeterminated frequency signal setting；, can be with curved using flexible material
It song, can carry with, each button on the keyboard made is subjected to predeterminated frequency signal setting；Every time one is tapped to press
Key can all send the sound of specific frequency corresponding with the button；In order to which other sound of frequency identical with environment differentiate
Come, the sound sent is modulated.
Step S2, tap keyboard generation keypad sounds and carry out keypad sounds collection；To each button on keyboard
Tapped, the sound of each button is gathered during key tap；The predeterminated frequency sound sent to key tap enters
Row modulation treatment.Mobile device is gathering the voice signal of surrounding always；Key is determined whether according to voice signal is collected into
Disk taps the appearance of event.
Step S3, judge that what is tapped is that button in keyboard according to the keypad sounds signal collected；In step S2
In the keypad sounds that collect, the not only knock of keyboard, while also with the noise hum pinched, in order to judgement
It is more accurate, it is necessary to be removed to noise noise, its process is as follows, whether have in S31, the voice signal for judging to gather by
Key taps sound, in this way, then performs step S32, such as otherwise deletes the voice signal of collection and perform step S31；S32, judgement
Whether there is noise in the voice signal of collection, in this way, then perform step S33, such as otherwise perform step S4；S33, the sound to collection
Sound signal denoising retain modulation after button tap voice signal and perform step S4；The process for removing noise is divided into two parts,
First, fixed frequency scope is set by target signal filter not in this range by Butterworth bandpass filter, in this step
In, remove the noise that other random frequency ranges are brought in surrounding enviroment.Secondly, with Wavelet Denoising Method or Kalman the methods of,
The removal of noise is carried out for the signal in the range of fixed frequency, in this step, removes those random noises or system noise
Sound.
Fixed frequency scope, refer in the system schema, on keyboard sound signal frequencies caused by all buttons be
In the range of specified interval.
Step S4, its corresponding character is shown according to the button judged.The character is fed back after character is shown
Key tap acoustic information carry out data preserve for contrast denoising.
Fig. 3 shows that this makes another object of the present invention is to provide a kind of flow chart of the application method of acoustic keyboard
Include mobile device and keyboard with method, details are as follows for it：
Step S10, mobile device and keyboard are fixed and open connecting valve startup fixed mode；Mobile terminal and keyboard are consolidated
It is fixed, junction switch is automatically opened up while fixed, starts fixed mode；One is set in mobile terminal and the junction of keyboard to open
Close, while connection in mobile terminal with keyboard, open switch, start mobile terminal and the relatively-stationary pattern of keyboard position.
Step S20, tap the corresponding button on keyboard according to the prompting on mobile device and be trained；Carried according to mobile terminal
Show button, i.e. training process corresponding to percussion.The process collection of training corresponds to the voice signal of button, calculates MFCC, LPCC etc.
Characteristic value；Button is trained as follows, S201, collects the voice signal that button is sent in each button on training keyboard；
S202, calculate each button MICC and LPCC characteristic value and store and arrive key value database；S202, according to the sound of button believe
Number, MICC and LPCC characteristic value calculates the weight data information for producing each button and preserves.Training obtains each keyboard
The data of button；The characteristic values such as the MFCC of each training data, LPCC are calculated, obtain training pattern.
Step S30, training finish percussion keyboard and send keypad sounds signal；Begin to use after training, tap
Keyboard, send the voice signal modulated of specific frequency corresponding with button；Tapping a button every time can all send
The sound of specific frequency corresponding with the button；, be to sending in order to which other sound of frequency identical with environment are distinguished
Sound be modulated.Begin to use after training, tap keyboard, send the modulation of specific frequency corresponding with button
Good voice signal.
Step S40, mobile device judge to tap that button of keyboard according to the voice signal of collection；Mobile device is collected
Sound, which key judge to tap jointly in combination with MFCC characteristic values according to the modulated signal of specific frequency is；According to frequency
Judge corresponding to keyboard percussion event it is which button；Judge that keyboard taps event according to characteristic values such as MFCC, LPCC simultaneously
For be which button；State further comprising the steps of in step S40：S401, according to the predeterminated frequency of each button judge
The voice signal collected corresponds to that button on keyboard；It is further comprising the steps of in the step S401：S4011, judgement are adopted
Whether there is button to tap sound in the voice signal of collection, in this way, then perform step S4012, such as otherwise delete the sound letter of collection
Number and perform step S4012；S4012, judge whether there is noise in the voice signal of collection, in this way, then perform step S, 4013,
As otherwise performed step S402；S4013, the voice signal tapped to button after the voice signal denoising reservation modulation of collection are simultaneously held
Row step S402.Button in S402, the MFCC in collected sound signal and LPCC characteristic value and key value database
MFCC and LPCC characteristic value contrast determines that button in corresponding keyboard；S403, using weights COMPREHENSIVE CALCULATING obtain tapping by
The weight data information of key finally gives the button result for tapping keyboard with the weight data information contrast preserved.
Step S50, corresponding character is shown in the plane of mobile device according to judged result.Comprehensive according to weights
To the button result finally tapped；Character corresponding to button is shown on the screen of the mobile device；Pressed according to the character of display
The weight feedback of key is adjusted to the weight data information that button is corresponded in database.
Have devised using flexible material can the Wireless Keyboard carried with of bending energy.Utilize keyboard simultaneously so that each
Individual button can send the voice signal modulated of predeterminated frequency, to reach mobile device only can be distinguished by sound
The function of the button tapped.The identification to Wireless Keyboard key tap can be met, identification stability is good, can carry with.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement made within refreshing and principle etc., should be included in the scope of the protection.
