Low-power consumption working mechanism is mutually switched by the activity pattern and deep sleep mode of chip to realize low-power consumption.
3. a kind of audio compression Transmission system based on low-power consumption bluetooth according to right 1, which is characterized in that described
Low-power consumption working mechanism is mutually switched by the activity pattern and deep sleep mode of chip to realize low-power consumption.
4. a kind of audio compression Transmission system based on low-power consumption bluetooth according to right 1, which is characterized in that institute
Stating more times of audio compression work principles is compressed encoding guaranteeing signal under the premise of not generating distortion in terms of the sense of hearing, to audio
Data-signal carries out compression as big as possible, and the method that Digital Audio Compression Coding takes existence of redundant in removal voice signal is come
It realizes.
5. a kind of audio compression Transmission system based on low-power consumption bluetooth according to right 4, which is characterized in that institute
It states existence of redundant and refers to the signal that cannot be perceived by the human ear in audio, they are to the tone color for determining sound, the information such as tone
There is no any help, redundant signals include audio signal outside human auditory system range and it is masked fall audio signal etc.,
That section of increment variation in sampled sound sample realizes lossless 2 times of compressions, is then based on sub-band adaptive differential pulse volume
The signal of code principle is divided into two subbands, and is encoded using ADPCM technology to the sample of two subbands, and realization has
Damage more times of compressions.
Compared with prior art, the invention has the following beneficial effects:
In the present invention, using more times of audio compressions, compressed encoding guarantee signal under the premise of not generating distortion in terms of the sense of hearing,
Compression as big as possible is carried out to voiceband data signal, Digital Audio Compression Coding takes existence of redundant in removal voice signal
Method realizes that so-called existence of redundant refers to the signal that cannot be perceived by the human ear in audio, they are to the sound for determining sound
Color, the information such as tone do not have any help, redundant signals include audio signal outside human auditory system range and it is masked fall
Audio signal etc., that section that increment changes in sampled sound sample realize lossless 2 times of compressions, be then based on subband from
The signal for adapting to differential pulse coding principle is divided into two subbands, and using ADPCM technology to the sample of two subbands
It is encoded, realizes more times of compressions, due to the limit of the limitation of single transmission data length and transmission speed between ble and mobile phone
System, we must optimize the transport protocol of oneself, so that our audio transmission is gone out under very narrow bandwidth, we pass through
Data and more bag datas one verification are continuously transmitted to guarantee that transmission speed and transmission packet loss re-transmission are asked with each band serial number
Topic, our primary recipient ends often receive n packet and wrap to a verification, and transmitting terminal sends to be feedback, such classes such as each 2n packet
The mode for being similar to sliding window guarantees that feedback is withouted waiting for when sending n-th of packet can send next n packet, in next n packet
Last packet verification packet is received in transmission process, if error serial number data is retransmitted in error, do not malfunction then the current packet of hair backward
Concurrent next packet, guarantees to send in this way and does not have the waiting time and reach high-speed transfer, reduces battery consumption, enhancing battery life,
Realize the transmission of ble audio data, transmission speed is very fast, realizes ios, and all kinds of Android mobile phones receive audio data by ble, and real
Translation result is handed down to bluetooth equipment by ble by existing mobile phone translation, brings better prospect of the application.

Specific embodiment
In a specific embodiment, it will describe clear and complete the audio compression based on low-power consumption bluetooth in conjunction with attached drawing and pass
The detailed process of defeated system.It should be pointed out that these descriptions are example, the range being not intended to limit the present invention.In addition,
In the following description, descriptions of well-known structures and technologies are omitted, obscures idea of the invention to avoid unnecessary.
Specific step is as follows:
To guarantee to realize the function of low-power consumption, it can decide whether suspend mode according to the state of recording, the power consumption of waste is reduced with this, lead to
Cross key press indicate microphone start to record, recording is detected, in certain time without recording enter semidormancy state,
Again it is more than certain time to enter complete dormant state, there is the non-suspend mode live pick-up of recording, there is recording semidormancy state setting
State is recorded again, is had the complete dormant state of recording to reinitialize and is recorded again, to realize low-power consumption, recording data passes through more multiplication of voltages
By equipment Bluetooth transmission to Bluetooth of mobile phone, Bluetooth of mobile phone changes into text by speech recognition for contracting, is turned over by character translation generation
Transliteration frequency generates translation audio and is transmitted to equipment under more times of compressions, and equipment, which receives compressed data and carries out decompression Data Concurrent, to be sent
Audio is played to playback equipment, the low-power consumption working mechanism is mutually cut by the activity pattern and deep sleep mode of chip
Realization low-power consumption is brought, using more times of audio compressions, compressed encoding does not generate the premise of distortion in guarantee signal in terms of the sense of hearing
Under, carry out compression as big as possible to voiceband data signal, Digital Audio Compression Coding take in removal voice signal redundancy at
Point method realize that so-called existence of redundant refers to the signal that cannot be perceived by the human ear in audio, they are to determining sound
Tone color, the information such as tone do not have any help, and redundant signals include audio signal outside human auditory system range and covered
The audio signal etc. fallen is covered, that section that increment changes in sampled sound sample realizes lossless 2 times of compressions, be then based on son
Signal with adaptive difference pulse code principle is divided into two subbands, and using ADPCM technology to two subbands
Sample is encoded, and realizes more times of compressions, due to the limitation of single transmission data length and transmission speed between ble and mobile phone
Limitation, we must optimize the transport protocol of oneself, so that our audio transmission is gone out under very narrow bandwidth, Wo Mentong
Cross continuously transmit data and more bag datas one verification come and each band serial number guarantee transmission speed and transmission packet loss re-transmission
Problem, our primary recipient ends often receive n packet and wrap to a verification, and each 2n packet of transmitting terminal transmission etc. is to be feedback, in this way
Guarantee that feedback is withouted waiting for when sending n-th of packet can send next n packet similar to the mode of sliding window, in next n
Last packet verification packet is received in packet transmission process, if error serial number data is retransmitted in error, not malfunctioning then, hair is current backward
Concurrent next packet is wrapped, guarantees that transmission does not have the waiting time and reaches high-speed transfer in this way.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
