Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the invention will be further described.
Realize the autism of children auxiliary therapeutic equipment of class dolphin sound Vltrasonic device, as it is shown in figure 1, include master controller, DAC modulus conversion chip, ultrasonic transmission device；Master controller carries out data communication with DAC modulus conversion chip by IIC interface, and DAC modulus conversion chip and ultrasonic transmission device carry out data communication by IIC interface.
Master controller U1, by the multiple dolphin audio sample signal that will gather, carries out FFT, thus obtains dolphin audio frequency characteristics value；
DAC modulus conversion chip U2, the dolphin audio frequency characteristics value of the multiple sample obtained by master controller carries out frequency band and chooses, and chooses the audio frequency characteristics value output of multiple different frequency section, the audio frequency characteristics value choosing out is converted to analogue signal；
Ultrasonic transmission device, including the supersonic generator of multiple different frequency sections；The audio frequency characteristics value that will export through DAC modulus conversion chip, is converted into mechanical output, according to the difference of frequency, selects the supersonic generator output of respective frequencies section, thus simulates the sound wave being similar to dolphin sound.
The following is a specific example.
100 the dolphin audio sample signals collected can be passed through FFT by master controller, former sound is carried out signal processing, dolphin audio sample signal is converted into discrete digital signal, obtains the eigenvalue of these dolphin audio samples；The dolphin audio frequency characteristics value of the multiple sample obtained after FFT processes then is chosen by DAC modulus conversion chip, select 8 frequency bands that in eigenvalue, signal is more concentrated (can choose multiple, select 8 for citing) herein, and respectively take a signal from these 8 frequency bands, the signal of these 8 different frequency sections is converted into analogue signal, IIC signaling interface is pushed in ultrasonic transmission device the supersonic generator output of different output frequency；
100 dolphin audio samples (citing 100 herein that master controller can will collect, quantity is indefinite according to the actual requirements) signal passes through FFT, former sound is carried out signal processing, dolphin audio sample signal is converted into discrete digital signal, obtain the eigenvalue of these dolphin audio samples, the eigenvalue of each sample is ranked up；And the dolphin sound eigenvalue of all samples of acquisition after FFT processes is chosen by user according to the actual requirements by DAC modulus conversion chip, select the signal of 8 different frequencies, the signal (dolphin sound eigenvalue) of these 8 different frequencies is converted into analogue signal, is pushed to ultrasonic transmission device output from 8 analog signal outputs of DAC modulus conversion chip respectively；
The signal behavior of 8 different frequencies can be function user-defined according to client, such as: 8 frequency bands more can concentrated according to signal in all sample characteristics, a signal (dolphin sound eigenvalue) is selected as DAC output signal, the signal of these 8 different frequency sections to be converted into analogue signal from each frequency band respectively；
One dolphin audio sample dolphin audio frequency characteristics value after FFT is probably 40K, 100K, 30K, 50K, 60K, 3K ...；Another dolphin audio sample dolphin audio frequency characteristics value after FFT is probably 35K, 90K, 60K, 50K, 2K, 3K ...；
Such as the 1st, 2,3 ... 100 dolphin audio samples are through FFT, then after sequence, frequency signal (eigenvalue of dolphin audio sample) between 35KHz-40khz is concentrated the most, and namely the dolphin audio frequency characteristics value frequency of occurrences in this 35KHz-40khz frequency band is the highest；In 35KHz-40khz frequency band, then take a signal as the audio frequency characteristics value choosing out；Analogize in this approach, until selecting the audio frequency characteristics value of 8 different frequency sections；
Selecting 8 frequency signals in this case is due to only with a DAC chip, according to 2 DAC chip, i.e. may select 16 frequency signals, therefore chooses how many frequency signals and select the quantity of DAC chip to determine by client.
Master controller uses SP3306 or SP3308 of Wuxi silicon utility companies；The part signal that dolphin audio sample signal exports after FFT is as shown in Figure 2；
The electric principle of the present invention is as shown in Figure 3；Master controller U1 connects DAC modulus conversion chip U2 by IIC interface；The reference voltage input terminal of DAC modulus conversion chip U2 meets the reference voltage VREF of a 10v；Reference voltage VREF by reference voltage chip U5 by supply voltage VCC(12v) convert；
DAC modulus conversion chip U2 uses AD5669R chip, for a kind of high integration Direct Digital Frequency Synthesizers (DDS), this chip internal is integrated with at a high speed, high-performance D/A converter and comparator, maximum clock reference frequency is up to 125MHz, it is possible to choosing the signal (the audio frequency characteristics value selected) of multiple different frequency section in the eigenvalue by multiple collecting samples exported by master controller U1 and exporting；Through DAC modulus conversion chip U2 conversion rear section signal output example as shown in Figure 4；
Ultrasonic transmission device includes supersonic generator T1～T8 of 8 different frequency sections；Supersonic generator includes ultrasonic transducer；Eight analog signal outputs of DAC modulus conversion chip U2 connect supersonic generator T1～T8 of 8 different frequency sections respectively；
The photovoltaic conversion of 12V is become the reference voltage of 10V by reference voltage chip U5, the signal of 8 different frequency sections that DAC modulus conversion chip U2 chooses is carried out dividing potential drop, it is converted into the pulse signal that maximum amplitude is 10V, is pushed on the ultrasonic transducer of different frequency section, thus reduce class dolphin sound；
Ultrasonic transmission device includes that supersonic generator T1～T8 of 8 different frequency sections, corresponding frequency band are: 2000Hz-10000Hz, 10000Hz-20000Hz, 20000Hz-30000Hz, 30000Hz-50000Hz, 50000Hz-70000Hz, 70000Hz-80000Hz, 80000Hz-90000Hz, 90000Hz-100000Hz.Owing to the Hz-KHz of single sonotrode is limited, it is therefore desirable to the supersonic generator combination of multiple different frequency sections；DAC modulus conversion chip U2 difference output signal can superposition, therefore ultrasonic transmission device can accept different frequency section signal value input；In such as Fig. 3, tri-analog signal outputs of A, B, F of DAC modulus conversion chip U2 export the signal being positioned at 2000Hz-10000Hz, 10000Hz-20000Hz, 70000Hz-80000Hz different frequency section respectively；The sound wave of supersonic generator T1, T2 and T6 output respective frequencies.
Dolphin occurrence frequency is the sound wave of the multi-wavelength of 2000Hz～100000Hz, the high frequency sounds of this uniqueness, cannot capture higher than 20kHz part normal human, the sound wave of the multi-wavelength of 2000Hz～100000Hz however but can be to infantile autism, cerebral palsy, the patients such as mongolism are in the neuronal cell of " dormancy " state and produce strong impact and stimulation, it can make child have one to loosen sense, for the central nervous system of child, there are good facilitation and medical value, autism children can be improved by easy stages link up, cognition and linguistic competence, stop the intensification of its stereotyped behavior.But, fostering of one dolphin is with high costs, for marine organisms, each patient home is allowed to have the real genus of a dolphin unrealistic, dolphin sound is effective in cure to autism children, if being realized by technological means by the sound of dolphin, allows each patient home be carved with the scene that dolphin is accompanied when can have seemingly, become the auxiliary therapeutic equipment of autism children, abundant autism children treatment technology field.
Some technical terms that the present invention relates to are explained as follows:
FFT:Fast Fourier Transform, is the highly effective algorithm of a kind of discrete Fourier transform (DFT), referred to as fast fourier transform.
DAC:Digital to Analog Converter, digital analog converter.
IIC:Inter-Integrated Circuit, IC bus.
