Multiple screw holes for being used to for panel being fixedly mounted on intercommunication terminal shell 4, after intercommunication terminal shell 4 is adapted to front panel 1
It is installed with fastened by screw, then carries out front panel 1 and intercommunication terminal shell 4 to assemble installation, form an intercommunication terminal equipment.
Further, the pickup microphone 244, position are located at the parallel position of postposition chamber 243, pickup microphone 244
Installation chamber be greater than postposition chamber 243, two chambers herein cross to be formed a step for limit pickup microphone 244 pacify
Holding position recycles microphone PCB component 245 that pickup microphone 244 is fixed in microphone sheath body 24.
Further, intercommunication terminal mainboard 3 is fixed in intercommunication terminal front panel 1 by screw rod, is provided with master control electricity
Road and control module, due to need to consider winter rain and snow weather cause mesh enclosure 21 and film 22 can freeze endure cold so that influence radix saposhnikoviae
It makes an uproar effect, microphone sheath body is set in the surface of microphone sheath body 24 or the sheath body parallel with 244 installation site of pickup microphone and is added
Thermal modules 246, microphone sheath body heating module 246 accesses intercommunication terminal mainboard 3 by conducting wire, when microphone sheath body heating module 246
On temperature-detecting device when detect environment temperature lower than set temperature, would automatically turn on heating module to melt mesh enclosure
21 and 22 surface of film icing, when temperature rises to the preset temperature upper limit, intercommunication terminal mainboard 3 will stop to microphone sheath body
Heating module 246 is powered.
Specifically, intercommunication terminal mainboard 3 is provided with governor circuit and control module, the governor circuit detects microphone sheath body
Temperature sensor signal on heating module 246, when environment temperature is lower than 1 DEG C, the governor circuit of intercommunication terminal mainboard 3 is to control
Module sends power supply instruction, and microphone sheath body heating module 246 starts to heat；When detecting 246 temperature of microphone sheath body heating module
Inductive signal feedback information, when real time environment temperature is higher than 20 DEG C, the governor circuit of intercommunication terminal mainboard 3 is automatically stopped control mould
Block, for electricity output, as long as the process intercommunication terminal is powered at the beginning, will constantly recycle inspection to microphone sheath body heating module 246
It surveys, heat up and automatically powers off.
By both examples above as it can be seen that
When air-flow by film and is arranged in preposition chamber and postposition chamber after the dual reduction wind speed of sponge, pickup miaow
Wind noise in collected voice signal will decrease to the noise signal of very little, then be filtered by intercommunication terminal main circuit
Wave and digital processing, wind make an uproar influence will be reduced to it is minimum, thus achieve the effect that radix saposhnikoviae make an uproar；Winter rain and snow weather, mesh enclosure and thin
Film, which can freeze, to be endured cold and then influences radix saposhnikoviae and make an uproar effect, surface or the set parallel with pickup microphone installation site in microphone sheath body
