Fig. 1 is noise reduction verbal system overall schematic；

Fig. 2 is the composition structural representation of radome.

Specific embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment for being obtained, belongs to the scope of the utility model protection.

Fig. 1 is noise reduction verbal system overall schematic, and noise reduction verbal system includes illuminating lamp 28, luminous lamp switch 27th, terminal box 26, industrial telephone set 24, installation backboard 23, blimp 22, acousto-optic bell ringing device 21 and noise cancelling headphone.Illuminating lamp 28 Typically energy-saving LED lamp is adopted, directly powered using low-voltage dc power supply, it is safer.Luminous lamp switch 27 is used using band The microwave inductive switch of light intensity sensor realizing, the light intensity of microwave inductive switch automatic detection surrounding enviroment, when light intensity reaches Regardless of whether there is librarian use all to open illuminating lamp 28 during certain brightness；It is microwave induced when light intensity is less than certain brightness Device is checked in current environment with the presence or absence of human body, worked if there is then automatic-control illumination lamp 28 automatically.Industrial telephone set 24 It is fixed in blimp 22 by installing backboard 23, acousto-optic bell ringing device 21 is fixed on the outside top of blimp 22.

Earphone wiring hole 25 is additionally provided with industrial telephone set 24, user as needed can connect the tone frequency channel wire of noise cancelling headphone To on earphone wiring hole 25, realize being received calls content by noise cancelling headphone.Typically adopt headphone.When local environment is made an uproar When sound is not more than 85dB levels, preferentially connection is set up using the hanging high-performance anti-noise industry telephone terminal being installed in blimp Network, such as experience communication effect is not good, can flexibly switch to earphone call mode, it is ensured that normal talking is not affected by environment.Work as institute When place's ambient noise is more than 85dB levels, can directly select and be conversed using head-mounted noise reduction earphone, can effectively intercept outside height and make an uproar Impact of the sound to normal talking.

When there is incoming call, signal is given microprocessor by bell sound detecting circuit, and microprocessor is beaten to acousto-optic bell ringing device signal Switch triggering is opened, ringing signal is sent on loudspeaker by operation amplifier 120DB signals, is also turned on the power supply of flash lamp, is made Flash lamp is started working, and microprocessor automatically can close the loudspeaker of acousto-optic bell ringing device and flashing light when receiving calls.Electricity Phone has also done dial-up circuit, and we can be dialled the number by dial setting speed, carry machine auto dialing number and dial electricity Words number, carries out usual telephonic communication.The busy tone detecting module of telephone set will detect that busy tone, automatic hand-up, prevent that the line is busy, Guarantee that phone at any time can jingle bell.

Fig. 2 is the composition structural representation of radome, and the cover wall of blimp is made to being respectively arranged with fiberglass outside to inside Shell 1, deadening felt 2, acoustical cotton 3, non-woven fabrics 4 and abatvoix 5, abatvoix using regularly arranged full aperture plastic material, As PVC board is made.Wherein non-woven fabrics 4 and deadening felt 2 can be arranged according to selection.Noise is successively through shell 1, deadening felt 2, sound-absorbing Effectively reduced after cotton 3 and non-woven fabrics 4, realized good soundproof effect.Simultaneously when the noise of periphery passes through sound insulation Cover and entered other openings or gap is entered when conversing space, because abatvoix 5 is provided with regularly arranged aperture, can have The effect for playing sound-absorbing of effect, therefore be capable of achieving further to reduce the noise in call space.Blimp with elimination except making an uproar The effect of sound, is also particularly industrial telephone set and has preferable protective action to the miscellaneous equipment of its inside.Shell 1 adopts glass Steel material, with high anticorrosive property and anti-riot effect.Being frequently encountered in actual communication process according to user needs record Need, desk, the important information in convenient use person's record communication process are provided with radome or in radome.

It may also be necessary to preventing ambient noise from scurrying into microphone, in the voice of the user that is added to, other end is affected to use The reception of person.Industrial telephone set adopts dual microphone Dolby circuit, dual microphone Dolby circuit to include two same sizes Electret Condencer Microphone and microphone process circuit, one be main microphon, another is noise microphone；Noise microphone and main words Cylinder is separately positioned on the two sides of microphone, and centre is provided with sound-insulating member, and noise microphone is connected on respectively microphone with the output end of main microphone Two inputs of the difference amplifier of process circuit；Sound-insulating member can be realized by directly pcb board being arranged on into centre Or realized using other sheet materials with soundproof effect.When normal voice is conversed, near main microphone, it produces larger sound to face Frequency signal Va, at the same time, noise microphone more or less can also obtain some voice signals Vb, but it is more much smaller than Va, this Two differential input ends of the difference amplifier of two signal input microphone processors, that is, put again after two paths of signals is subtracted each other Greatly, the signal for then obtaining is Vm=Va-Vb.If having powerful connections noise in use environment, because source of sound is remote from telephone set , so as the intensity of sound wave is almost when reaching two microphones of telephone set, that is, the Va ≈ Vb of background noise, in It is that, for background noise, although two microphones are all to pick up, but Vm=Va-Vb ≈ 0 are as can be seen from the above analysis, so Design can effectively resist the ambient noise interference of telephone set periphery, greatly improve the definition of normal talking.

Disclosed above is only a kind of embodiment of the utility model, can not limit the utility model with this certainly Interest field, one of ordinary skill in the art will appreciate that realize all or part of flow process of above-described embodiment, and according to this reality The equivalent variations made with new claim, still fall within the scope that utility model is covered.
