Embodiment 1, this embodiment, the wireless earphone of children is also one in the wireless earphone such as bluetooth headset, involves technical principles such as the constitution and the data communication of bluetooth headset, and this embodiment does not need to be repeated. Such as a processor chip, a power supply, a receiver, a transmitter, a codec function unit, etc. included in the bluetooth headset itself, are not considered to be within the scope of the present embodiment.
According to the scheme, application upgrading is carried out only by depending on the basic functions of the wireless earphone, and the wireless earphone is used as a management background (such as APP for data interaction with the wireless earphone) of the wireless earphone and needs to participate in data processing.
As shown in fig. 1, in one aspect, the present application provides a wireless headset for children with a function of promoting sleep, the wireless headset comprising:
1. the audio signal acquisition unit is used for acquiring noise audio data around the wireless headset of the child and transmitting the noise audio data to the processor through a receiver of the wireless headset of the child;
the audio signal acquisition unit is mainly used for acquiring noise audio data around the wireless earphone of the child in real time, acquiring the real-time noise data through a built-in audio data stream acquisition program and transmitting the acquired noise data to the processor through the receiver of the wireless earphone of the child, and the processor can further analyze and process the noise data;
as shown in fig. 2, in this embodiment, when noise audio data around the wireless headset of the child is collected, a built-in audio data stream collection program firstly needs to collect and send a current audio value to a processor, and after the current audio value is calculated by the processor, whether the current audio value exceeds a preset noise protection value is determined, for example, whether the current audio value exceeds 40 decibels is determined, and if the current audio value exceeds 40 decibels, the current audio value is processed by the processor, and a next phase reversal cancellation step is performed; if not, the process is abandoned.
And audio data flow, namely acquiring audio data according to the sampling frequency, and reporting the currently acquired audio data flow regularly according to 1-3 sampling periods.
2. The frequency spectrum inverse generation unit is used for calculating to obtain a frequency spectrum interference signal opposite to the frequency spectrum information of the noise audio data according to the frequency spectrum information of the noise audio data;
the currently collected audio data stream, namely the audio data collected from the noise audio data around the wireless earphone of the child, can obtain the frequency spectrum signal data in the current noise audio data through the extraction and processing of the frequency spectrum signal, so as to obtain the frequency spectrum of the current noise. If the spectrum shows more than e.g. 40 db, a harmonious processing is required.
An audio frequency with a frequency spectrum opposite to the noise frequency is generated through the wireless earphone, and the audio frequency is harmoniously counteracted.
When the audio frequency spectrum of the currently collected audio data stream is analyzed and obtained, a symmetrical inverse frequency spectrum can be generated, and offset audio is regenerated according to the symmetrical inverse frequency spectrum.
As shown in fig. 3, a graph of the spectral signal of a noisy audio data stream during one sampling period a. In this embodiment, an inverse frequency spectrum is generated according to the noise spectrum in the period, as shown in fig. 4, the frequency spectrum signal of the inverse frequency spectrum and the frequency spectrum signal of the noise audio data stream are symmetrical to each other, and after the inverse frequency spectrum generates the corresponding audio data stream, the audio data stream is played to cancel the inverse frequency spectrum.
In this embodiment, although the period from the collection to the noise audio data stream will be subjected to the spectrum signal mirroring and playing, the time for the processor to process the signal data is calculated by microseconds and can be ignored. Within the sampling period, for example, 0.05 to 0.5 second, the inverse audio signal at the current time node can be emitted at almost the same time, except for the propagation distance of the sound wave.
3. The audio interference unit is used for generating corresponding audio interference data based on the frequency spectrum interference signal and sending the audio interference data to the playing unit of the wireless headset of the child through the processor;
the audio interference unit is mainly used for generating a corresponding audio signal according to a frequency spectrum signal in the currently acquired noise audio data stream, and when the audio is played, a sound wave which is symmetrical to the current noise is emitted so as to counteract the noise.
As shown in fig. 5, the audio interference data of the inverse audio frequency spectrum generated by the audio interference unit is sent to the playing unit of the wireless headset of the child through the processor for playing, so as to perform ablation and cancellation processing on the noise audio frequency of the current time period.
The playing unit is used for receiving the audio interference data and playing the audio interference data so as to offset the noise audio data;
the playing unit can be the original playing unit of the wireless earphone, and the audio interference data forwarded by the processor is received and played to offset the noise audio data.
The audio signal acquisition unit, the frequency spectrum inverse generation unit, the audio interference unit and the playing unit are respectively and electrically connected with the processor.
Functional modules of the respective units will be described below.
As an optional implementation of the present application, optionally, the audio signal collecting unit includes:
the audio acquisition module is used for acquiring noise audio data around the wireless earphone of the child in real time;
the compression module is used for performing real-time lossless data compression on the noise audio data according to a preset data compression algorithm to obtain a compression packet of the noise audio data;
and the transmitting module is used for transmitting the compressed packet of the noise audio data to the processor according to the sampling frequency of the noise audio data.
The audio acquisition module is started regularly according to a preset acquisition frequency and acquires noise data around the earphone. In order to save electricity, the audio acquisition module does not need to be continuously started and is started according to the set sampling frequency. For example, every 3 seconds, or when the processor or the background finds that the size of the received external audio exceeds 30 db, the collection program of the noise audio is started. Less than 30 db does not require start-up.
The noise audio data stream collected in real time can be coded and decoded according to the format of the original coding and decoding unit of the wireless earphone. In order to improve the transmission efficiency, the embodiment uses a data compression algorithm to perform real-time lossless compression on the encoded file of the noise audio data stream, so as to obtain a compressed packet of the noise audio data. The data compression algorithm is not limited, and the data encoding and decoding mode of the embodiment only needs to refer to the original functions of the wireless earphone.
And the transmitting module, namely the transmitter, of the earphone transmits the sampling frequency of the noise audio data to the processor, and waits for further calculation and analysis of the processor.
As an optional implementation of this application, optionally, the audio signal acquiring unit further includes:
the frequency setting module is used for setting the sampling frequency of the audio acquisition module and the reporting frequency of the transmitting module;
the audio acquisition module acquires the noise audio data in real time according to the sampling frequency;
and the transmitting module reports the compressed packet of the noise audio data to the processor according to the reporting frequency.
The audio acquisition module and the transmission module both need to work according to a set working frequency, so a frequency setting module is needed for setting the sampling frequency of the audio acquisition module and the reporting frequency of the transmission module. The user can operate the frequency setting module to set the sampling frequency of the audio acquisition module and the reporting frequency of the transmitting module in a background parameter configuration mode. After setting, the operation is carried out according to the sampling frequency.
In this embodiment, regarding the calculation of the sampling frequency and the sampling period, the processor performs the calculation according to the specific parameters set.
As an optional embodiment of the present application, optionally, the wireless headset for children further includes:
the data processing unit is used for receiving the noise audio data and analyzing the noise audio data to obtain frequency spectrum information of the noise audio data;
the data processing unit is electrically connected with the processor.
The noise audio data is a segment of audio data stream, and the frequency spectrum information on the current time segment is recorded on the noise audio data stream. Therefore, it is necessary to analyze the data to obtain spectral information of the noise audio data. The analysis here is performed similarly following the set operating frequency/period.
As an optional embodiment of the present application, optionally, the data processing unit includes:
the receiving module is used for receiving the compressed packet of the noise audio data and forwarding the compressed packet to the analysis module;
the analysis module is used for analyzing the compressed packet of the noise audio data obtained under each sampling frequency according to a preset analysis algorithm to obtain noise audio information;
and the frequency spectrum processing module is used for generating the frequency spectrum information of the noise audio data according to the noise audio information.
And after receiving the compressed packet, the processor forwards the compressed packet to the analysis module. And the analysis module analyzes the compressed packet of the noise audio data according to a preset analysis algorithm (only conventional data file analysis software) to obtain the noise audio data stream and the noise audio information in the noise audio data stream. The noisy audio information is shown according to the sampling frequency, and the audio signal values at the nodes of each sampling period are shown on a frequency spectrum diagram, such as the frequency spectrum diagram shown in fig. 2. The frequency spectrum processing module adopts corresponding frequency spectrum processing software to analyze and process the current audio data stream, and carries out pattern drawing on the obtained noise audio information to generate a frequency spectrum signal in a corresponding sampling period. Conventional spectrum processing programs can be adopted for processing, for example, existing recording software or song listening software can analyze and output the recorded spectrum signal graph of the audio data stream in real time.
As an optional implementation of this application, optionally, the spectrum inverse generation unit includes:
the frequency spectrum importing module is used for importing the frequency spectrum information of the noise audio data into frequency spectrum application, generating a corresponding frequency spectrum signal diagram of the noise audio data and storing the frequency spectrum signal diagram;
the frequency spectrum mirror image module is used for carrying out mirror image processing on the frequency spectrum signal image to obtain a frequency spectrum signal mirror image which is symmetrical to the waveform of the frequency spectrum signal image;
the frequency spectrum processing module is used for detecting signal wave crests and/or wave troughs in the frequency spectrum signal mirror image and judging whether wave crests and/or wave troughs exceeding a signal preset value exist or not:
and if so, moving the corresponding signal wave crest and/or wave trough to the position where the signal preset value is located, and obtaining an interference spectrum opposite to the spectrum information of the noise audio data.
The frequency spectrum reverse generation unit mainly has the functions of generating a symmetrical reverse frequency spectrum according to a noise frequency spectrum signal diagram and then generating a corresponding interference frequency spectrum according to the reverse frequency spectrum.
After the processor obtains a frequency spectrum signal image of noise audio data, a frequency spectrum signal image which is symmetrical to the waveform of the frequency spectrum signal image is generated by adopting a mirror image frequency spectrum technology. Mirror spectrum, see the prior art explanation of frequency mirror or DDS mirror spectrum provided by "https:// blog.csdn.net/hunterhuang 2013/article/details/55098924".
And the frequency spectrum processing module is mainly used for detecting signal wave crests and/or wave troughs in the frequency spectrum signal mirror image and judging whether the wave crests and/or the wave troughs exceeding the preset value of the signal exist. The reason for this is that if some peaks and/or valleys are too large, if a corresponding audio data stream is generated according to a spectral signal mirror image and played, an inverse noise as large as noise may be generated, and although the inverse noise may be reduced as compared to the original noise, the inverse audio frequency having a high decibel continuously may not be excluded, which may cause a sleep effect. Therefore, the corresponding signal peak and/or trough is moved to the position where the signal preset value is located, and then the corresponding interference spectrum is generated.
As an optional embodiment of the present application, optionally, the audio interference unit includes:
the interference audio frequency generation module is used for receiving and generating corresponding audio frequency interference data according to the interference frequency spectrum;
and the audio distribution module is used for synchronously distributing the audio interference data to each playing unit of the wireless headset for children through the processor.
With the interference frequency spectrum, the interference audio generation module can generate corresponding audio interference data, namely the interference audio data stream for counteracting the noise data stream at the current frequency, according to the interference frequency spectrum, and distribute the interference audio data stream to each playing unit of the earphone for playing so as to counteract the external noise.
In this embodiment, the earphone is not only provided with one playing unit, but also provided with a plurality of playing units, and simultaneously receives the interference audio data streams forwarded by the processor, and after playing, the interference audio data streams resist noise from the outside.

The earphone shell cover 1 of each wireless earphone for children is internally provided with three playing units which send out audio data streams for offsetting external noise together.
Consequently, this application carries out noise audio frequency harmony, filtration processing with external noise through the children wireless headset who uses this product at children when sleeping, through launching the sound wave with noise frequency antiphase, offsets noise data.
