Electroacoustic call or wireless communication operating mode are selected by key, while the gas breathed out is by the outlet valve on breathing mask
Exhalation path flow direction on when air-breathing (open when expiration, close), shell is extraneous；When not in use, it turns off the switch, from breathing mask
On unload sound pick-up and communication main body, be packed into dedicated box in case saving.
Wireless communication：The voice signal of sound pick-up acquisition wearer is sent to audio codec, and analog signal is converted shape
At digital signal, digital signal is then sent to digital signal processor (DSP) and carries out the compression of multi-slot speech information, frame data
Transmitting, multi-path voice data multiplexing synthesize and the place of the bulk informations such as related control information, data information, external data interface
Reason, distribution and coordination.Frame data are sent to modulation of the RF transmit-receive circuit completion to information, the radiofrequency signal for carrying information is sent
Power is improved toward radio-frequency front-end amplifier, is launched finally by antenna.Reception is to believe the radio frequency that information is carried in space
Number by antenna receive, amplify, demodulate, decompressing, frame data receive, D/A convert to form simulated voice information, pass through ear
Plug receiver restores speech information.Channel, volume can be adjusted, be selected by key " △ ", " setting " and " ▽ "
Same channel, suitable volume can be conversed.
Electroacoustic call：Sound pick-up gives speech information to audio codec and analog signal is converted to digital signal, so
Digital signal is given afterwards and gives audio codec D/A conversion after DSP is handled, gives analogue voice signal to audio function
Rate amplifier improves power, and the speech of clear amplification can be heard by loudspeaker.It can be to loudspeaking by key " △ " and " ▽ "
Device volume is adjusted.
The present invention can select electroacoustic call or wireless communication operating mode by key, and the functional and operating process of institute is logical
Menu setting is crossed, earphone voice prompting facilitates personnel to use.And having the function of automatic voice PTT, when speech, does not need to operate
Ptt switch, speech automatically activate transmit circuit, control transmitting.Wireless communication uses time-division duplex working method (TDD),
Realize duplex call.Group-net communication uses time division multiple acess (TDMA) asynchronous communication Networking protocol, can both realize a little to any multiple spot
Broadcast type call, can also be achieved between more people duplex call simultaneously.
Above-described embodiment, only presently preferred embodiments of the present invention, is not intended to limit the invention practical range, therefore all with this
The equivalent variations that content described in invention claim is done should all be included within scope of the invention as claimed.
