Embodiment
The embodiments of the invention provide a kind of ears wireless headset and the audio frequency playing method of ears wireless headset, main earphone1 by wireless communication module receive audio frequency apparatus 3 transmission come voice data, then main earphone 1 by NFMI by after codingVoice data is sent to from earphone 2 so that main earphone 1 and from the playing audio-fequency data simultaneously of earphone 2, is solved and is regard RF as earsTechnical difficulty that the application of bluetooth earphone is caused is big, radiation hazradial bundle and the big technology of transmission power consumption may be caused to ask to human bodyTopic.
To enable goal of the invention, feature, the advantage of the present invention more obvious and understandable, below in conjunction with the present inventionAccompanying drawing in embodiment, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that disclosed belowEmbodiment be only a part of embodiment of the invention, and not all embodiment.Based on the embodiment in the present invention, this areaAll other embodiment that those of ordinary skill is obtained under the premise of creative work is not made, belongs to protection of the present inventionScope.
Fig. 1, Fig. 4 are referred to Fig. 6, the embodiments of the invention provide a kind of one embodiment of ears wireless headset, bagInclude：Main earphone 1, from earphone 2, the wireless communication module 11 being arranged in main earphone 1, main earphone 1 passes through wireless communication module 11It is connected with audio frequency apparatus 3, main earphone 1 is connected by NFMI with from earphone 2；It is understood that main earphone 1 passes through radio communicationModule 11 receives the voice data of audio frequency apparatus 3, and voice data is sent to from earphone 2 by NFMI, completes the main He of earphone 1Played from the audio of earphone 2；
It should be noted that the advantage that NFMI is applied to earpiece audio playback equipment has at 3 points；First, as shown in figure 1,NFMI power consumptions are ultralow, and transmission power is only 1.6Mw, and transmission rate is more suitable for minimizing the continuous of wireless headset up to 596kbpsETS estimated time of sailing；Second, as shown in Fig. 2 NFMI is operated under 10MHz~14MHz carrier frequency, tissue can be penetrated, to peopleBody more meets the usage scenario of wireless binaural ear speaker device almost without radiation injury；3rd, as shown in figure 3, NFMI transmission distanceSmall by external disturbance from short, ears wireless headset is an entirety.
Main earphone 1 also includes the first codified processor 12, the first coding and decoding module 13, the first audio player 14；Wireless communication module 11 is communicated to connect with the first codified processor 12, and connected mode is preferably by I2S link connections；FirstCodified processor 12 is connected by NFMI with from earphone 2, and is communicated to connect with the first coding and decoding module 13, the first codifiedThe communication connection mode of the coding and decoding module 13 of processor 12 and first is preferably by I2S link connections；First coding and decodingModule 13 is communicated to connect with the first audio player 14, and connected mode is preferably by I2S link connections.
Include the second codified processor 21, the second coding and decoding module 22, the second audio player 23 from earphone 2；TheTwo codified processors 21 are connected by NFMI with the first codified processor 12, and with the communication link of the second coding and decoding module 22Connect, the communication connection mode of the second codified processor 21 and the second coding and decoding module 22 is preferably by I2S link connections；Second coding and decoding module 22 is communicated to connect with the second audio player 23, and connected mode is preferably by I2S link connections.
Wherein the first codified processor 12 and the second codified processor 21 are both preferably NXH2280 chips, becauseNXH2280 chips possess super low-power consumption, and an integrated high-performance- M0 control system, a magneticSense (MI) transmitter, a voice data road strength and a power management subsystem.NXH2280 chips are based on high-performance- M4 kernels, and carry- M0+ coprocessors, are a double-core low-power chips.WhereinNXH2280 magnetic induction transceiver, its transmission rate is up to 596kbps, and carrier frequency is 10.579MHz, the humorous line of internal adjustableResonance is enclosed, low delay ear is optimized and is communicated to ear.NXH2280 audio transmission link is transmitted by I2S COBBAIFs, support pairMultiple audio sampling frequencies can arrive 48KHz, and internal mac accelerates to magnetic induction transmitter, the integrated delay control of internal 2 RX passagesDevice processed and adaptively sampled rate converter, using Programmable DSPs.NXH2280 chips have a variety of Peripheral Interfaces, includingUART/I2C/SPI/I2S etc..
Wireless communication module 11 can be bluetooth module, and when wireless communication module 11 is bluetooth module, the present invention is implementedThe ears wireless headset that example is provided is ears wireless Bluetooth headsets.
In embodiments of the present invention, main earphone 1 first can by bluetooth module receive audio frequency apparatus 3 transmission come audioData, are then converted into I2S data formats, then the NXH2280 chips by I2S link transmissions to main earphone by voice data,NXH2280 chips do appropriate delay to the voice data of main earphone, and wherein delay duration can be calculated by actual testArrive, while by audio data coding for G.722, and be sent to by NFMI from earphone 2；Then from the NXH2280 chips of earphone 2The voice data being encoded to G.722 can be received by NFMI and I2S data formats are decoded as, now, delay terminates, main earphone1 NXH2280 chips and NXH2280 chips from earphone 2 simultaneously by voice data by I2S link transmissions to the first coding solutionThe code coding and decoding module 22 of module 13 and second, the last audio player 23 of first audio player 14 and second plays the respectivelyOne coding and decoding module 13 and the second coding and decoding module 22 decode the voice data come, realize ears radio play soundFrequently.
Referring to Fig. 2, the embodiments of the invention provide a kind of implementation of the first of audio frequency playing method of ears wireless headsetExample, including：
101, main earphone receives the voice data that audio frequency apparatus transmission comes.
102, main earphone will be sent to from earphone by NFMI after audio data coding so that main earphone and from earphone simultaneouslyPlaying audio-fequency data.
In embodiments of the present invention, then main earphone passes through firstly the need of the voice data that audio frequency apparatus transmission comes is receivedNFMI will be sent to from earphone after audio data coding so that main earphone and from earphone playing audio-fequency data simultaneously.
Referring to Fig. 3, the embodiments of the invention provide a kind of implementation of the second of audio frequency playing method of ears wireless headsetExample, including：
201, main earphone receives the voice data that audio frequency apparatus transmission comes.
202, main earphone makees delay process to voice data, then by audio data coding be I2S voice datas form simultaneouslySent by NFMI to from earphone, after after the voice data for receiving I2S voice data forms from earphone, main earphone and from earphoneWhile playing audio-fequency data.
In embodiments of the present invention, main earphone is firstly the need of the voice data that audio frequency apparatus transmission comes is received, then to soundThen audio data coding is sent to from earphone for I2S voice datas form and by NFMI, treated according to delay process is made by frequencyAfter the voice data for receiving I2S voice data forms from earphone, main earphone and from earphone simultaneously playing audio-fequency data.
