The utility model provides a kind of In-Ear noise cancelling headphone, comprises auricular concha, places transducer, driver and circuit board in the auricular concha, also comprises a housing that places in the auricular concha, and described transducer, driver and circuit board are positioned in the described housing.
In the utility model,, on the one hand, guaranteed that above-mentioned device places the sealing of environment, reduced the influence of external noise, made the picking up more comprehensively of noise, more stable by transducer, driver and circuit board one are positioned in the housing; On the other hand, increased the integrated level of Headphone structure, made that the auricular concha internal structure is compacter, the earphone volume is littler, wears more comfortablely, carries more convenient.
Be described in detail below in conjunction with the specific implementation of accompanying drawing the utility model embodiment.
Referring to figs. 1 through Fig. 4, the structural representation of a preferred embodiment of the In-Ear noise cancelling headphone that provides for the utility model.Described In-Ear noise cancelling headphone comprises an irregular auricular concha 1, places transducer 2, driver 3 and circuit board 4 in the auricular concha 1, also comprises a housing 5 that places in the auricular concha 1, and transducer 2, driver 3 and circuit board 4 are positioned in the housing 5.
Particularly, as an embodiment of the present utility model, housing 5 is one to have the cylinder of step 51, and housing 5 has the inner chamber 52 of hollow.And in step 51 places inner chamber 52 is divided into ante-chamber 521 with little internal diameter and the back cavity 522 with large diameter, wherein transducer 2 places in the ante-chamber 521, and driver 3 and circuit board 4 place in the back cavity 522.
As an embodiment of the present utility model, ante-chamber 521 has an opening 5211, and the sensitive surface of transducer 2 is towards opening 5211.Be positioned over back cavity 522 after driver 3 is inverted and near ante-chamber 521 places, the top of driver 3 is towards ante-chamber 521 like this, and the top of driver 3 is provided with the diaphragm (not shown).Like this, the sensitive surface of transducer 2 keeps identical with the direction of vibration of diaphragm, it is consistent with the direction that driver 3 passes through the diaphragm radiative acoustic wave to be that transducer 2 receives the direction of sound waves, helps transducer 2 and detect noise in duct and the auricular concha 1 better, more in all directions in real time after In-Ear Headphones is worn use.
Further, in order better driver 3 to be positioned in the housing 5,, also be provided with a support 6 in the housing 5 as an embodiment of the present utility model.Support 6 places in the ante-chamber 521 and covers on the transducer 2, and the top of support 6 is stretched in the back cavity 522, and driver 3 places on the support 6, and circuit board 5 places on the driver 3.
Particularly, with reference to Fig. 3, Fig. 4, support 6 comprises at least two legs 61 (shown in the figure being four) and is located at each leg 61 top and with its annular support plate 62 that is connected as a single entity.The outward flange of support plate 62 protrudes four circumferential edges that leg 61 surrounds, like this, support 6 is when putting into ante-chamber 521 in the back cavity 522, and the edge that support plate 62 protrudes is stuck in step 51 places between ante-chamber 521 and the back cavity 522 just, and four legs 61 then stretch in the ante-chamber 521.The inwall at opening 5211 places of ante-chamber 521 bends inwards and forms the leg 61 that supporting surface support is stretched into, and support 6 promptly is positioned in the ante-chamber 521 like this.The bottom of each leg 61 all has the grab 611 of inside level bending, and a plurality of grabs that bend inwards 611 also form a supporting surface, after putting in the mesopore of transducer 2 by annular support plate 62, and the supporting surface support fixation that the bottom forms by four grabs 611.
As an embodiment of the present utility model, paste fixing by double faced adhesive tape 7 between driver 3 and the support 6.Two-sided sticking two-sided sticking for EVA, the two-sided sticking adhesion strength of EVA is strong, good seal performance.On the one hand, driver 3 is firmly fixed on the support plate 62, on the other hand, also driver 3 tops is not had the diaphragm place and effectively seal, prevent that the sound wave of ante-chamber 521 and back cavity 522 from interfering mutually.
Further, in the present embodiment, circuit board 4 is fixedly welded on the bottom of driver 3.Adopt the fixing mode of this welding, fixation on the one hand, and convenient welding.
In the present embodiment, when In-Ear noise cancelling headphone is assembled, earlier transducer 2 is positioned on the leg 61 of support 6 bottoms, the driver 3 and the circuit board 4 that will be welded in one again are fixed on the support plate 62 by two-sided sticking 7, again the above-mentioned integral body that assembles is put into by the back cavity 522 of housing 5, at last place a ring-type gland 8 in opening 5221 places of back cavity 522, and adopt impact style that gland 8 is embedded in the back cavity 522, thereby circuit board 4 is fixed, and then placed the above-mentioned components and parts in the housing 5 to fix whole.At last, the more above-mentioned housing 5 that is built-in with above-mentioned components and parts is positioned in the auricular concha 1.Like this, by with transducer 2, circuit board 4, driver 3 in being positioned over housing 5, on the one hand both fixation of sensor 2, circuit board 4, driver 3 preferably, reduce it and occupy auricular concha 1 volume inside, can guarantee simultaneously each device mutually noninterfere again, and be not subjected to the influence of external environment condition, guarantee the tonequality that transmits.
As an embodiment of the present utility model, with reference to Fig. 1, also be provided with a cosmetic sheet 9 on the outside of auricular concha 1, cosmetic sheet 9 is provided with the mesh 91 that is connected with auricular concha 1.Mesh 91 forms the acoustic resistance mouth of earphone.These acoustic resistance mouths have the characteristic of adjusting damping coefficient and sound press output, and its perforated area and entrant sound amount are the balanced arrangement of noise reduction amplitude and frequency response response.
In the present embodiment, auricular concha 1 outside is provided with a dismountable ear muff 10.Ear muff 10 removably is sheathed on the auricular concha 1, makes things convenient for the user to change the ear muff of different size, therefore, uses more convenient.
In the present embodiment, also offer one on the outside of earmuff 1 and can stretch into the interface 11 that is connected with circuit board 4 for the audio signal connecting line.By interface 11 incoming audio signal connecting lines, earphone is connected with extraneous music player, and by the earphone listoning music.When earphone is worked, the environmental noise that transducer 2 detects between duct and the auricular concha, be transferred to an external noise reduction module (not shown) then, external noise reduction module feeds back to circuit board 4 after the overcoupled circuits computing, thereby transfer to the control signal that driver 3 obtains an optimum through circuit board 4 again and produce a sound wave and a noise waves counteracting opposite with the noise waves phase place, that energy equates, thereby reach the purpose of noise reduction.
Below only be preferred embodiment of the present utility model,, all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model not in order to restriction the utility model.
