It, can be in the U frequency ranges frequency modulation and institute by the high-gain aerial under bifrequency working condition in above structureIt states and is carried out at the same time middle rotating function between V-band frequency modulation, can be shown simultaneously by U channels viewing area and V channels viewing areaShow the working condition in the frequency zones U and the frequency zones V, and the blue bottom gradation split screen display available screen can be with by the photo resistanceAutomatically adjust susceptibility of the screen to light so that the indigo plant bottom gradation split screen display available screen is used in sunlight and bright placeAlso the content that can clearly see U channels viewing area and V channels viewing area, in making for duplexing double frequency type intercomWith in the process, sound size can be adjusted by the volume adjustment plectrum, by the encryption chip to intercomIt is protected.
In order to further increase the convenience that intercom uses, connected with buckle between the shell and the high-gain aerialIt connects, with snapping connection between the shell and the U frequency ranges frequency modulation.
In order to further increase the convenience that intercom uses, connected with buckle between the shell and the V-band frequency modulationIt connects, the loud speaker is embedded in the shell.
In order to further increase the convenience that intercom uses, the indigo plant bottom gradation split screen display available screen and the shell itBetween connected with gluing, the keyboard is embedded in the shell.
In order to further increase the convenience that intercom uses, it is connected between the microphone and the shell, instituteVolume adjustment plectrum is stated to inlay in the housing.
In order to further increase the convenience that intercom uses, it is connected between the rear cover and the shell, instituteIt states and is connected by card slot between battery and the shell.
In order to further increase the convenience that intercom uses, it is connected between the controller and the shell,It is connected between the encryption chip and the shell.
Advantageous effect is：The utility model can carry out transmitted in both directions in synchronization information, can be while sayingAlso it can listen, be listened when saying, additionally be able to carry out protection encryption, safety more convenient to use to intercom.
