The utility model discloses a light material alleviates the dead weight to adopt active noise reduction circuit noise reduction, develop the rescue work under the adaptable strong noise environment, make to keep clear accurate information to communicate between the first -aid staff, improved the efficiency of rescue work.
Description
Technical field
The utility model relates to communication technical field, is specifically related to a kind of light-duty active anti-noise earphone and telephone transmitter.
Background technology
Existing earphone and telephone transmitter communication speech poor definition under high-noise environment, carries out rescue work under being difficult to adapt to high-noise environment, affects the communicating information between rescue personnel, reduce the efficiency of rescue work.And weight is large, wearing comfort is poor.
Summary of the invention
The technical problem that the utility model solves: a kind of light-duty active anti-noise earphone and telephone transmitter of design, adopt light material, alleviate deadweight, and adopt active noise reduction circuit to reduce noise, rescue work is carried out under can adapting to high-noise environment, make between rescue personnel, to keep clear communicating information accurately, improve the efficiency of rescue work.
Technical solution of the present utility model: a kind of light-duty active anti-noise earphone and telephone transmitter, comprise left earmuff, right earcup, headring, transmitter and cable plug, described left earmuff, right earcup are connected to the two ends of headring, transmitter and cable plug are connected to the below of left earmuff, it is characterized in that: described left earmuff and right earcup internal upper part are all equipped with noise reduction receiver, Dolby circuit and pick-up noise electret are all equipped with in middle part, and communication receiver is all housed in bottom and the back side of communication receiver is coated with dust-proof screen cloth; Described noise reduction receiver is electrically connected with pick-up noise electret by Dolby circuit.
Described transmitter is connected to the below of left earmuff by rotating seat, and can rotate within the scope of 300 °.
Ear pad is provided with inside described left earmuff and right earcup.
Described left earmuff and right earcup all adopt carbon fibre material to make, and described ear pad adopts polyurethane foam material to make.
The utility model compared with prior art has following beneficial effect:
1, the utility model communication receiver separates with noise reduction receiver and works, and by the break-make of switch control rule noise reduction receiver, improve the independence of product, also can carry out voice call when not opening decrease of noise functions;
2, the utility model transmitter is articulated with below left earmuff outside, can 300 ° of flexible rotatings, and improve the up-down adjustment scope of transmitter bar, easy to use, user can regulate transmitter to the distance of mouth according to actual conditions, guarantees that communication effect is best;
3, the utility model cup material adopts light carbon fibre material, and overall weight alleviated about 30% than originally, and ear pad uses polyurethane foam material simultaneously, wear soft comfortable, coincide tightly with around people ear, reduce leakage sound, alleviate the fatigue problem wearing generation for a long time.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is the internal structure schematic diagram of the left earmuff of the utility model and right earcup.
Embodiment
1,2 a kind of embodiment of the present utility model is described by reference to the accompanying drawings.
A kind of light-duty active anti-noise earphone and telephone transmitter, comprise left earmuff 1, right earcup 2, headring 3, transmitter 4 and cable plug 5, described left earmuff 1, right earcup 2 are connected to the two ends of headring 3, and transmitter 4 and cable plug 5 are connected to the below of left earmuff 1.Described left earmuff 1 and right earcup 2 internal upper part are all equipped with noise reduction receiver 7, and Dolby circuit 8 and pick-up noise electret 9 are all equipped with in middle part, and communication receiver 10 is all housed in bottom and the back side of communication receiver 10 is coated with dust-proof screen cloth 11; Described noise reduction receiver 7 is electrically connected with pick-up noise electret 9 by Dolby circuit 8.
Described transmitter 4 is connected to the below of left earmuff 1 by rotating seat, and can rotate within the scope of 300 °.Ear pad 6 is provided with inside described left earmuff 1 and right earcup 2.Described left earmuff 1 and right earcup 2 all adopt carbon fibre material to make, and described ear pad 6 adopts polyurethane foam material to make.
The utility model is to leaking into the ambient noise in earmuff by after the pickup of pick-up noise electret, undertaken amplifying by Dolby circuit again and after anti-phase process, release via noise reduction receiver, this anti-phase noise and the noise bled in earmuff are cancelled out each other, and realize the object of noise reduction.
Above-described embodiment, just preferred embodiment of the present utility model, is not used for limiting the utility model practical range, therefore all equivalent variations done with content described in the utility model claim, all should be included within the utility model right.
