Embodiment

By describing technology contents of the present utility model, structural feature in detail, being realized purpose and effect, below in conjunction with execution mode and coordinate accompanying drawing to be explained in detail.

See also Fig. 1 to Fig. 4, the utility model toneable earphone comprises an earphone case, is located at a sound-producing device 30 and a tuning device 40 in earphone case.Form resonant cavity between sound-producing device 30 and earphone case.Particularly, earphone case comprises bass housing 10 and covers together high pitch housing 20 with bass housing 10.20 of described sound-producing device 30 and high pitch housings form earphone high pitch inner chamber 50, and described sound-producing device 30 surrounds earphone bass inner chamber 60 with bass housing 10.

Offer a sound regulating hole 12 on bass housing 10, high pitch housing 20 rear ends are formed with a sender 21.Offer a bleeder port 11 on bass housing 10, particularly, bass housing 10 has the horn body that a column and stretches out and forms from column one end, offer a described sound regulating hole 12 on column and run through the described bleeder port 11 that bass housing 10 top sidewalls communicate with sound regulating hole 12, making earphone bass inner chamber 60 communicate with extraneous space.Bass housing 10 tops offer a loose slot 13 corresponding to bleeder port 11 places, and air-flow will be beneficial to regulate the air pressure in resonant cavity by flowing out by sound regulating hole 12 and bleeder port 11 in earphone bass inner chamber 60, and then reaches the effect of tuning.The experiment proved that, the difference of the aspects such as bleeder port 11 quantity, shape, size designs can make earphone have different sound performances, therefore in actual applications, and can be according to different demands and quantity, shape and the size of flexible design bleeder port 11.Bass housing 10 top outer rims are concaved with a groove 14.

Please continue and consult Fig. 2 and Fig. 3, tuning device 40 comprises that one is rotatably mounted in tuning bonnet 41 and the damping body 42 on bass housing 10.Tuning bonnet 41 further comprises a cylindrical shell (not indicating in figure) and an adjustable baffle 413 that covers all or part of bleeder port 11.Cylindrical shell has a closing cap 411 and and vertically extends to form sealing cylinder 412 from closing cap 411 peripheries, sealing cylinder 412 medial margins inwardly convex with a guide vane end stop 414, guide vane end stop 414 is placed in loose slot 13, and guide vane end stop 414 can rotate between loose slot 13 both sides cell walls.Baffle 413 is assembled in bass housing 10 inboards corresponding to bleeder port 11, be interspersed in sound regulating hole 12, and the inside die-cut short slot 415 that has of the corresponding bleeder port 11 of a side of baffle 413, sealing cylinder 412 inwardly convexes with fin 416 away from closing cap 411 1 end medial margins, fin 416 rotatably is sticked in groove 14, and baffle 413 1 ends are connected with closing cap 411.When the cylindrical shell of turn tuning device 40, cylindrical shell can drive baffle 413 synchronous rotaries, blocks all or part of described bleeder port 11 thereby baffle 413 is rotating.

The rounded sheet of the corresponding sound regulating hole 11 of damping body 42 can be made by the material that wire netting, nylon cloth etc. has a gas permeability, and damping body 42 gears are located at sound regulating hole 12 places between column and horn body.

See also Fig. 5, the figure shows when baffle 413 rotates to diverse location the variation of the frequency curve of the utility model toneable earphone.This figure has intercepted the frequency range of human auditory system, and (in 20HZ ~ 20KHZ), the utility model toneable earphone is in bleeder port 11 reflection to sound during in different shielding status.By the relative position of rotation baffle 413 and then adjustment short slot 415 and bleeder port 11, can reach the gas output of control sound intracavity gas and the purpose of flow velocity, thereby different auditory perceptions is brought up in the reflection that produces different bass frequencies response curve.Particularly, when rotation baffle 413 is not communicated with bleeder port 11 to short slot 415, namely close fully, this moment, bass was the most weak, and the frequency response curve of its bass is curve III demonstration in figure; When rotation baffle 413 short slots 415 were communicated with fully with bleeder port 11, this moment, bass was the strongest, and the frequency response curve of its bass is curve I demonstration in figure; When short slot 415 with bleeder port 11 not fully at once, the frequency response curve of its bass is that in figure, curve II shows.

In sum, the utility model toneable earphone drives baffle 413 synchronous rotaries by the cylindrical shell of turn tuning device 40, block all or the described bleeder port 11 of part thereby baffle 413 is adjustable, and sound regulating hole 12 place's gears are established described damping body 42, the auxiliary pressure of adjusting in earphone bass inner chamber 60, so can make the utility model toneable earphone that different low-frequency sound performances can be arranged, thereby can satisfy better different users's demand.
