Embodiment
Mobile device is modal flip type electronic device, and wherein, the mobile device of flip-shell all has a loam cake and a lower cover.The present invention is provided with a loud speaker and a microphone respectively at the loam cake and the lower cover of flip type electronic device.
As shown in Figure 3, the disclosed flip cover of the present invention is opened the closed condition method, comprises the following steps:
Step 100: make loud speaker export a special sound wave, execution in step 110 then.Because, the frequency range that common people can hear is 20Hz～20KHz, hear the special sound wave that loud speaker sends for fear of the user, therefore, the special sound wave that loud speaker is sent can not be in the scope of 20Hz～20KHz, wherein, this special sound wave is just exported by loud speaker every a set time T.Therefore, the special sound wave that loud speaker is exported is an one-period property interruption voice signal, to reduce the electric energy that this loud speaker is consumed.
The special sound wave that loud speaker is sent can be a melody, in order to increase identifiability.In addition, and the loudness of the special sound wave that loud speaker is exported needs greater than background noise, if the loudness that loud speaker is exported is too big, will causes the sensitivity of opening closed condition of flip cover formula electronic installation to reduce, and increases the power consumption of flip type electronic device.The background noise of general environment is about 30 decibels, and in the present embodiment, the loudness that loud speaker is exported is about 40～60 decibels.
Step 110: microphone receives one and detects sound wave, and execution in step 120 then.Because microphone can receive the sound wave in the fixed frequency band, therefore, the first frequency of the special sound wave that loud speaker is sent and first loudness need in the scope that microphone can receive.During minimum loudness that first loudness of the special sound wave of exporting when loud speaker more can receive near microphone, the sensitivity of opening closed condition of the expression judgement flip type electronic device height of healing then.
Suppose that loud speaker is arranged at the loam cake of flip type electronic device, and microphone is arranged at the lower cover of flip type electronic device.Because the mechanism design difference of flip type electronic device will have an attenuation decibel between loud speaker and the microphone, therefore, the loudness that loud speaker is exported deducts the loudness behind the attenuation decibel, need be positioned at the scope that microphone can receive.If the mechanism design of electronic installation is good, then attenuation decibel is near 0 decibel.
Step 120: frequency and the loudness of judging the detection sound wave that microphone received.Because sound wave comprises frequency and loudness, therefore,, can learn just whether microphone receives the special sound wave that loud speaker is exported so as to judging the frequency and the loudness of the detection sound wave that microphone received.
Equal the first frequency of special sound wave when the frequency of the detection sound wave that microphone received, the expression detection sound wave that microphone received is the special sound wave that loud speaker is exported, and when the loudness that detects sound wave is preset loudness more than or equal to one, the expression special sound wave that microphone received meets the loudness size that lid is closed, execution in step 130.
If the frequency of the detection sound wave that microphone is received is not equal to first frequency, the expression detection sound wave that microphone received not is the special sound wave that loud speaker is exported.Or the frequency of the detection sound wave that microphone received equals first frequency but loudness during less than default loudness, and at this moment, then execution in step 140.
Wherein, because the loudness of the sound wave that loud speaker is exported need be positioned at the loudness scope that microphone can detect, therefore, above-mentioned default loudness is in the loudness scope that microphone can detect.When default loudness by microphone during the detected minimum loudness of energy, then expression judges that the sensitivity of opening closed condition of flip type electronic device is the highest.
When the angle of the loam cake of flip type electronic device and lower cover during, then be judged as closed condition less than a predetermined angle.In the present embodiment, suppose that default angle is 5 degree.Therefore, equal 5 when spending with the angle of loam cake and lower cover, the loudness size that microphone received is default loudness.
Step 130: because loud speaker and microphone are arranged at the loam cake and the lower cover of flip type electronic device respectively, therefore, when the frequency of the detection sound wave that microphone received equals first frequency, and when the loudness of the sound wave that microphone received during also more than or equal to default loudness, loam cake and the lower cover of then representing flip type electronic device are very approaching, so judge that flip type electronic device is a closed condition, then, execution in step 100 again, make loud speaker continue to send special sound wave, can continue the closed condition of opening of flip cover formula electronic installation.
As described in step 100,, but when the detected loudness variation of microphone is preset changing value greater than one, then reduce set time T just loud speaker is sent special sound wave every a set time T.When the detected loudness variation of microphone is preset changing value less than one, then increase set time T.
Step 140:, make microphone can't receive the special sound wave that loud speaker is exported when the loam cake of flip type electronic device is started.Therefore, when the loudness of the detection sound wave that microphone received less than default loudness, or the frequency that detects sound wave is when being not equal to first frequency, represents that then the loam cake of flip type electronic device is started, is in open mode.Then, execution in step 100 makes loud speaker continue to send special sound wave, can continue the closed condition of opening of flip cover formula electronic installation.
Below will embodiments of the present invention be described at clamshell handset.Fig. 4 a shows the schematic diagram of clamshell handset.As shown in the figure, clamshell handset 30 is an open mode, and is made up of a loam cake 31 and a lower cover 32, and wherein, loam cake 31 comprises: a loud speaker 33 (being commonly called as loudspeaker) and a screen 35.Lower cover 32 comprises: a keyboard 34 and a microphone 36.Be positioned at the loud speaker 33 and the microphone 36 that is positioned at lower cover 32 of loam cake 31, be arranged on corresponding position.According to the mechanism design difference of flip type electronic device, the position of microphone and loud speaker is different, generally speaking, is arranged on corresponding position.
Fig. 4 b shows clamshell handset schematic internal view of the present invention.As shown in the figure, loud speaker 33 is just sent a special sound wave every an interrupt cycle, and microphone 36 is in order to receive sound wave, and wherein, scope detection time of microphone 36 need comprise the time range of the special sound wave of loud speaker 33 outputs.In the present embodiment, the detection time of microphone is between 1/100 second to 1 second.
When mobile phone remained on closed condition or open mode, then the detected loudness of microphone changed less; When mobile phone becomes open mode by closed condition, or when becoming closed condition by open mode, the detected loudness of microphone changes greatly.
When the loudness variation is preset changing value less than one, represent that then mobile phone remains on closed condition or open mode, at this moment, be first interrupt cycle interrupt cycle of the special sound wave that loud speaker is sent.
When the loudness variation is preset changing value greater than one, the expression mobile phone is that open mode becomes closed condition, or becomes open mode by closed condition, and then be second interrupt cycle interrupt cycle of the special sound wave sent of loud speaker, wherein, first interrupt cycle is greater than second interrupt cycle.
In other words, when mobile phone is that open mode becomes closed condition, or when becoming open mode by closed condition, then the interrupt cycle between each special sound wave of sending of loud speaker is shorter; When mobile phone remained on closed condition or open mode, then the interrupt cycle between each special sound wave of sending of loud speaker was longer.
After microphone 36 receives sound wave, then judge the frequency F and the loudness A of the sound wave that microphone 36 is received by processing unit 40, wherein, processing unit 40 is analog-digital converter ADC and the digital signal processor DSP in the present ubiquity electronic product.Processing unit 40 is judged the closed condition of opening of mobile phone 30 according to frequency F and loudness A.
When mobile phone 30 was closed condition, then loam cake 31 was very near lower cover 32, and therefore, microphone 36 can correctly receive the special sound wave that loud speaker 31 is sent.When processing unit 40 detects, the frequency F of the sound wave that microphone 36 is received equals first frequency, and the loudness A of sound wave judges that then mobile phone 30 is closed condition during more than or equal to default loudness.
When mobile phone 30 was open mode, then loam cake 31 increased with the distance of lower cover 32, causes, and the loudness A of the sound wave that microphone 36 is received diminishes.When processing unit 40 detects, the frequency F of the sound wave that microphone 36 is received is not equal to a predeterminated frequency, or loudness A represents that then mobile phone 30 is open mode, and starts corresponding function during less than a default loudness.
Because under the situation that the volume of electronic product day by day dwindles, profit of the present invention has existing assembly, need not increase other assembly, just can correctly judge the closed condition of opening of flip type electronic device, not only saves hardware space at present, and reduce the cost of electronic installation.
Though the present invention with preferred embodiment openly as above; right its is not in order to qualification the present invention, any insider, without departing from the spirit and scope of the present invention; when can doing a little change and retouching, so protection scope of the present invention is as the criterion when looking claims person of defining.
