A kind of method that more equipment play audio simultaneously, step include:
(1) mobile phone speaker plays；
(2) information is delivered to main system control module by BLE bluetooth module in such a way that BLE is transmitted by mobile phone；
(3) main system control module is by instructing information conveyance to audio output module；
(4) audio output module is played by device speaker；
(5) it completes while playing audio, terminate.
Further, instruction is also delivered to audio collection module and handled information by (3) main system control module.
Beneficial effects of the present invention:
Bluetooth BLE, that is, low-power consumption bluetooth, predecessor are the Wibree technologies of NOKIA exploitation, are mainly used for realizing intelligent movable
Being continuously connected between terminal and periphery accessory, is the extremely low short-distance wireless communication technology of power consumption, and effective propagation path
It has been thus lifted to 100 meters or more.The advantages of bluetooth BLE is relative to conventional Bluetooth: maximized stand-by time, quickly connection and low
The transmission of peak value/reception power consumption.
This project is that the transmission that audio is realized using customized agreement and Wireless Losses inspection are transmitted based on BLE agreement
It surveys, to reach maximum data integrity, best data playback effect is provided, so that loudspeaking of the voice transmission to equipment
In device, to play sound.
This method does not influence mobile phone not only and normally uses function, can realize hand with normal play sound of mobile phone audio
Machine sowing playback frequency or while answer the call, translation stick can also play audio, ensure that the normal continuous of work carries out.
Detailed description of the invention
Fig. 1 is the connection schematic diagram for the method that the more equipment of the present invention play audio simultaneously；
Fig. 2 is the flow diagram for the method that the more equipment of the present invention play audio simultaneously.
Specific embodiment
The present invention will be further described in detail below based on the drawings and embodiments.
Fig. 1 is the connection schematic diagram for the method that the more equipment of the present invention play audio simultaneously, referring to Fig.1, the present invention, more equipment
The method for playing audio simultaneously, comprising:
Main system control module 1, BLE bluetooth module 2, audio collection module 3, audio output module 4, volume control module 5,
System power management module 6, ESD protective module 7.
Main system control module 1 is the instruction source of whole device, uses as the core component of apparatus of the present invention
DA14681, which is used as, uses model, which supports newest 4.2 standard of bluetooth, integrated power supply pipe
Unit (PMU) is managed other than it can efficiently power for an on piece charger and voltameter, additionally provides 3 independent power supplys
Rail is more external system power elements, and can be battery charging by USB interface, its unique architecture can be complete for one
Whole Internet of things system power supply, without additional external electrical power management circuits.
BLE bluetooth module 2 is embedded in above system main control module, for being connect by the transmission of BLE agreement with mobile phone.It is logical
Cross setting BLE bluetooth module 2, may be implemented with BLE and mobile communication, transmit the function of audio.
Audio collection module 3 connects main system control module 1, handles for receiving instruction audio-frequency information, at this
In case study on implementation, double MIC modules are used, this double MIC module can have the processing capacity that noise reduction is carried out to audio-frequency information,
Echo can also be eliminated simultaneously.
Audio output module 4 connects main system control module 1, exports audio-frequency information for receiving instruction, uses
Model nau88l24 can provide excellent audio performance with the battery capacity of power saving, and it is good vertical to include energy-saving effect
Body sound D class loudspeaker driver and the G class headphone driver for carrying powerful earphone detecting circuit technology, at the same support jack insertion/
It exits, microphone detecting, different key/short key/long keys/cipher key distribution detecting, microphone has detecting, loudspeaker impedances are detectd
Survey, the detecting of earphone cross-talk and elimination etc., can play highest sound quality and eliminate any undesirable frequency component.
Audio frequency control module 5 is connected to above system main control module 1, for adjusting volume.
System power management module 6 is connected to above system main control module 1, for receiving instruction control power supply.
