Summary of the invention
The purpose of this utility model provides a kind of communication public address set, it can realize communication and sound amplification function simultaneously, and can overcome existing public address set acoustic shortcoming clearly inadequately, realize the real-time clear transmission of voice signal, this communication public address set is simple and compact for structure in addition, when the setting of not having a plug-in communication annex makes it be used for safety eyewear, can improve its safety in utilization.
According to the foregoing invention purpose, the utility model proposes a kind of communication public address set, it is connected with a microphone, and described communication public address set also is connected with external communications equipment, and described communication public address set comprises:
One power supply is for described communication public address set provides electric power output;
One receiver unit, it comprises: a receiver; And a callee signal receiving and analyzing device that is connected with receiver, described callee signal receiving and analyzing device is connected with described external communications equipment, transmits it to receiver after receiving the signal of external communications equipment transmission;
One communication/mode conversion device amplifies, it comprises: a communication module, one amplifies trigger switch that module and is connected with the module that amplifies with communication module respectively, described trigger switch control communication module is connected with callee signal receiving and analyzing device, voice signal transfers to callee signal receiving and analyzing device after microphone is converted into the signal of telecommunication, callee signal receiving and analyzing device transmits it to described external communications equipment, thereby realizes and extraneous communication;
One speaker unit, it comprises: a loud speaker; An and loud speaker end signal receiving and analyzing device that is connected with described loud speaker, described trigger switch is controlled the module that amplifies and is connected with described loud speaker end signal receiving and analyzing device, voice signal transfers to loud speaker end signal receiving and analyzing device after microphone is converted into the signal of telecommunication, loud speaker end signal receiving and analyzing device transfers to loud speaker with the described signal of telecommunication, loud speaker broadcasts after the signal of telecommunication is converted into voice signal, thereby realizes the amplification of sound.
Preferably, described communication public address set also comprises an arc bracing frame, and described callee and loud speaker end are located at the two ends of described arc bracing frame respectively.The setting of this arc bracing frame is to wear the communication public address set for the ease of operating personnel.
Preferably, described speaker unit also is covered with a dust cover outward, thereby prevents that speaker unit is subjected to the influence of dust atmosphere, thereby causes the reduction of its operating accuracy.
Preferably, described communication public address set and external communications equipment wireless connections.
Communication public address set of the present invention can be realized communication state and the conversion of the state that amplifies by trigger switch in the course of the work.
When operating personnel need carry out speech communication with the external world, by pushing trigger switch, communication module is connected with receiver unit, this moment, voice signal was converted to the signal of telecommunication by microphone, this signal of telecommunication imports the callee signal receiving and analyzing device that is connected with communication module via connector, the callee signal analysis device transfers to connected external communications equipment with this signal of telecommunication again, thereby operating personnel's voice transfer is arrived communication object.Correspondingly, the signal of the corresponding feedback of communication transfers to receiver via the callee signal analysis device, and receiver is a voice signal with this conversion of signals, transfers in operating personnel's the ear.
When operating personnel need amplify its voice, by pushing trigger switch, the module that amplifies is connected with loud speaker end signal receiving and analyzing device, this moment, voice signal was converted to the signal of telecommunication by microphone, this signal of telecommunication imports the loud speaker end signal receiving and analyzing device that is connected with the module that amplifies via connector, transfer to loud speaker by it again, thereby realize the amplification of sound.
This shows, communication public address set described in the utility model can be realized communication and sound amplification function according to operating personnel's different needs, and can overcome existing public address set acoustic shortcoming clearly inadequately, realize the real-time clear transmission of voice signal, this communication public address set is simple and compact for structure in addition, when the setting of not having a plug-in communication annex makes it be used for safety eyewear, can improve its safety in utilization.
