Description
Technical field
The utility model is related to a kind of voice-control toy.
Background technology
At present, due to different people or equipment, all there is more or less difference in its sound so that the sound of voice-control toy
Signal processing chip is difficult to correctly recognize the sound that different people or equipment send（That is sound control signal）, discrimination is relatively low,
This results in sound signal processing chip and is difficult to send correct sound or work according to the sound control toy that people or equipment send
Go out correct action.Often user wants toy and answers a question, but toy is but given an irrelevant answer；User wants toy forward
Walk or move forward, but toy is but walked backward or travelled backward.
This defect has had a strong impact on the playability of voice-control toy so that these voice-control toys cannot be easily accepted by a user, because
This is difficult to see the trace of voice-control toy in the market.
Content of the invention
Technical problem to be solved in the utility model is low for prior art sound control accuracy rate, has a strong impact on
The shortcoming of the playability of toy, provides a kind of voice-control toy, and this voice-control toy can greatly improve the accuracy rate of sound control,
Greatly increase the playability of toy.Using technical scheme as follows：
A kind of voice-control toy, including toy body, is provided with control circuit in toy body, it is characterised in that：The control
Circuit includes voice signal input unit, receives receivable voice signal；Sound signal outputting device, sends with high frequency sound
The voice signal of sound control signal；High-frequency sound signal processing apparatus, process receivable voice signal, will be with high-frequency sound
The voice signal of control signal is sent to sound signal outputting device；Power supply, power supply.
Preferably scheme, the high-frequency sound signal processing device are set to high-frequency sound signal processing chip.
Preferably scheme, the receivable voice signal be another equipment send with high-frequency sound control signal
Voice signal.
Preferably scheme, the voice signal with high-frequency sound control signal, be the sound that can be heard by human ear and
The mixing sound that the high-frequency sound that human ear cannot be heard is mixed.
Below its principle is simply introduced：Voice signal, i.e. audio signal are actually a kind of energy wave, its profit
Propagated with air or other media, the sense of hearing is to the size of sound experience degree with loudness energy decibel (dB) as estimating list
Position.It is referred to as audible ripple (audible sound) when the vibration frequency of this energy wave is in the range of human ear can sense.When frequency
Then claim ultrasonic (ultrasound) when rate is higher than heard sound, be referred to as high-frequency sound in the application, be typically used for medical science or work
The detection of journey or the processing of material.As for frequency ratio audible ripple low when be referred to as bass ripple (infrasound), such as earthquake drawn
The seismic wave for rising.The audibility range of the mankind is the sound of 20Hz to 20kHz, and most sensitive scope is between 2kHz to 4kHz.Profit
After being tested to human ear with different simple signals, definitely masking curve (absolute can be described with a curve
Threshold curve) or quiet masking curve (quiet threshold curve).And human auditory system
Model (psychoacoustic model) is to emulate human auditory system using a frequency analyzer, and this frequency is divided
Parser is made up of many bandpass filters, its frequency be about 20Hz to 20kHz between, each bandpass filter
Bandwidth is different from, and the bandwidth of these bandpass filters is referred to as critical band (critical bands).Thus human ear is listened
Feel that model can summarize two important masking characteristics, real-time domain capture-effect and frequency domain capture-effect.The former is subdivided into elder generation
Masking (pre-masking), rear masking (post-masking) and synchronous masking (simultaneous-masking).When
Audio frequency has multi-frequency composition while when occurring, then now different frequency composition capture-effect will accumulation calculating simultaneously, hide
Covering curve becomes very complicated, can be different with energy size, the change of frequency location and characteristics of signals of signal.
The big signal of energy can cover the shielding of larger noise, non-single-frequency (non-tonal) signal than single-frequency (tonal) signal
Good, high-frequency signal has stronger shielding than low frequency signal.Audio frequency watermark (audio watermark) is to be intended to embedded water
Official seal number, causes the watermark signal randomization after processing after encryption, coding, spread spectrum or other process.And according to the mankind
The capture-effect (masking effect) of auditory system (Human Auditory System, HAS), after process
Watermark or its spectral components control and are embedded in the shieldable scope of original audio signal, you can be smoothly hidden in watermark
In audio signal, and people will not be allowed to feel the difference on audio quality.Steganography (steganography) is also numeral
A kind of application of watermark, both sides can be linked up using the information that hides in a digital signal.Usual high-frequency sound signal transacting
Chip and miscellaneous equipment be by selecting several frequencies in the less sensitive high frequency section of human ear, being entered using frequency in audio frequency
Mobile state blind code, Min. destroy original sound frequency characteristic on the premise of hide encoded signal, and this with
The sound of frequency can relatively resist the interference of context to encode.
Due to sending and receiving the voice signal with high-frequency sound control signal using high-frequency sound signal processing apparatus,
Therefore the sound for allowing user be thought that human ear can be heard is controlled to toy, indeed through with high-frequency sound control
High-frequency sound control signal control in the voice signal of signal, this causes the control of toy very accurate, and in accuracy rate
While significant increase so that toy can be interactive with user：Mutually speech exchange, or toy to user by mobile phone,
The voice that another identical voice-control toy etc. sends（Voice signal with high-frequency sound control signal）Make in action
Reaction.
Preferably scheme, the frequency range of the high-frequency sound is 17-21kHz.
More excellent scheme, the frequency range of the high-frequency sound is 19.1-19.9kHz.Certain so can be avoided as far as possible
A little higher people of sensitive ears degree hear high-frequency sound, do not feel like oneself.
More excellent scheme, another equipment are that the acoustic control that can send the voice signal with high-frequency sound control signal is played
Tool or mobile phone.
More excellent scheme, the mobile phone are smart mobile phone.
Preferably scheme, the voice signal input unit are microphone.
Preferably scheme, the sound signal outputting device are loudspeaker.
Preferably scheme, the toy body are additionally provided with executing mechanism, the executing mechanism and high-frequency sound signal transacting
Chip is electrically connected.The high-frequency sound signal processing chip control action mechanism work.
The utility model beneficial effect against existing technologies is, due to employing high-frequency sound signal processing chip, because
This can receive and send the voice signal with high-frequency sound control signal so that the acoustic control of toy is very accurate, playability
Higher, and the effective control cost of toy.
