The utility model content
The purpose of this utility model provides a kind of intercommunication noise reduction public address set for commander.
According to an aspect of the present utility model, a kind of intercommunication noise reduction public address set for commander is provided, comprise noise cancelling headphone, to the microphone of noise cancelling headphone input audio signal, receive noise cancelling headphone output audio signal loudspeaker and with the intercom of noise cancelling headphone transmission of audio signal.
The utility model adopts noise cancelling headphone, in fight or training, can effectively reduce the noises such as shot, report, noise cancelling headphone has been equipped with intercom simultaneously, make the commander in fight or training, can clearly grasp combat or transmit war communique by intercom, and noise cancelling headphone has been equipped with loudspeaker, make that the commander can information clearly be delivered in team member's ear with fighting all, improved and fought or the efficient of training.
In some embodiments, noise cancelling headphone can be the active mode denoise earphone.Thus, the active mode denoise earphone not only can reduce the noises such as shot, report effectively, and, can also amplify the bass such as speech etc., the sense of hearing of battlefield or training place noise circumstance there is very big help.
In some embodiments, loudspeaker can be waist-mounted type loudspeaker.Thus, loudspeaker can be hung on the tactics waistband, easy to carry.
In some embodiments, intercom can be wireless interspeaker.Thus, can in movement, use, and some multiple spot ground be carried out communication.
In some embodiments, can also comprise the audio signal wire that is provided with switching device, intercom is by audio signal wire and noise cancelling headphone transmission of audio signal.Thus, can control switching on and off of intercom by the switch on the audio signal wire.
In some embodiments, can be provided with clip on the switching device of audio signal wire.Thus, audio signal wire can be clipped on the clothes, thereby alleviate audio signal wire to the heavy burden of noise cancelling headphone.
Description of drawings
Fig. 1 is the principle of compositionality block diagram of the intercommunication noise reduction public address set that is used for commander of a kind of execution mode of the utility model.
Fig. 2 is the structural representation of an embodiment that has comprised the intercommunication noise reduction public address set that is used for commander of each functional unit shown in Figure 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in more detail.
Fig. 1 has schematically shown the principle of compositionality block diagram of the intercommunication noise reduction public address set that is used for commander of a kind of execution mode of the utility model.
As shown in Figure 1, microphone 2 is to noise cancelling headphone 1 input audio signal, and noise cancelling headphone 1 is transferred to loudspeaker 3 after audio signal analysis is processed, and loudspeaker 3 amplifies the audio signal that receives and the loud speaker that drives loudspeaker 3 is sounded; Simultaneously, noise cancelling headphone 1 is transferred to intercom 4 after the audio signal analysis of microphone 2 inputs is processed, intercom 4 sends to other intercom with the audio signal that receives, perhaps intercom 4 receives the audio signal that other intercom sends, and audio signal transmission carried out analyzing and processing to noise cancelling headphone 1, and the loud speaker that drives noise cancelling headphone 1 is sounded.
Fig. 2 has schematically shown the structural representation of an embodiment of the intercommunication noise reduction public address set that is used for commander that has comprised each functional unit shown in Figure 1.
As shown in Figure 2, the intercommunication noise reduction public address set for commander comprises noise cancelling headphone 1, microphone 2, loudspeaker 3 and intercom 4.In addition, can also comprise audio signal wire 5.
In the present embodiment, noise cancelling headphone 1 adopts the active mode denoise earphone.In other embodiments, noise cancelling headphone 1 also can adopt the passive type noise cancelling headphone.
Microphone 2 is located on the noise cancelling headphone 1, to noise cancelling headphone 1 input audio signal.
Loudspeaker 3 is connected with noise cancelling headphone 1 by the first audio signal wire 11, namely the first audio signal 11 is plugged on the corresponding interface of loudspeaker 3, loudspeaker 3 receives the audio signal of noise cancelling headphone 1 input, and audio signal is amplified, thereby the loud speaker that drives loudspeaker 3 is sounded.
In the present embodiment, loudspeaker 3 adopts waist-mounted type loudspeaker.In other embodiments, loudspeaker 3 also can adopt the public address equipments such as megaphone.
Intercom 4 is connected with noise cancelling headphone 1 by audio signal wire 5, the second audio signal wire 12.
Audio signal wire 5 is provided with switching device 51, paste a clip 52 on the switching device 51, be that switching device 51 can be controlled being switched on or switched off of intercom 4, clip 52 can be clipped in audio signal wire 5 on the clothes, alleviates the heavy burden of 5 pairs of noise cancelling headphones 1 of audio signal wire.
The second audio signal wire 12 is plugged in the corresponding jack of switching device 51, and the other end of audio signal wire 5 is plugged in the corresponding interface of intercom 4.
Intercom 4 transmits audio signal with noise cancelling headphone 1, and microphone 2 is to noise cancelling headphone 1 input audio signal, and noise cancelling headphone 1 is transferred to intercom 4 after audio signal analysis is processed, and intercom 4 sends to other intercom with the audio signal that receives; Intercom 4 receives the audio signal that other intercom sends, and audio signal transmission is carried out analyzing and processing to noise cancelling headphone 1, and the loud speaker of driving noise cancelling headphone 1 is sounded.
