Device connection, the host and the hand-held microphone carry out the transmission of voice signal by shielding line.
Preferably, have the function of selecting channel and send words and called on the host, send speech phase for passing hand-held microphone
The defeated voice signal to come is sent to radio frequency processing chip, and the voice signal modulated is then sent to radio frequency amplifying circuit,
The voice signal for being used to receive radio frequency amplifying circuit by speech phase demodulates, and is then sent to hand-held microphone by shielding line.
Preferably, have the function of selecting channel and transmitting in the hand-held microphone and listen to voice, transmitting voice is used for language
The collected voice signal of sound acquisition device is sent to the radio frequency processing chip of host by shielding line, listens to voice for will be from
The voice signal that host is sent is sent to loudspeaker arrangement.
Preferably, the voice acquisition device is microphone.
Preferably, the loudspeaker arrangement is loudspeaker.
Compared with prior art, the utility model has the beneficial effects that
The utility model host is only responsible for merely processing radiofrequency signal, and hand-held microphone is only responsible for merely processing audio signal, this makes
Small volume and less weight can be accomplished by obtaining host and hand-held microphone, and host is by carrying out transmitting voice signal between shielding line and hand-held microphone, as far as possible
Reduce the interference of external signal, communication quality is good, can allow user can be host is placed on loins in hand-held microphone shouldering
It can be carried out transmitting and listen to voice, carry easy to use, reduction radiation effect.
Detailed description of the invention
