Embodiment

By describing feature of the present utility model in detail, realized purpose and effect, give explanation below in conjunction with execution mode and conjunction with figs. are detailed.

See also Fig. 3, earphone 100 of the present utility model comprises an earphone case 110, a loudspeaker monomer 120 and an adjusting device 130.

Earphone case 110 is insulation crusts of a hollow, has a front bulkhead 111, one and the aft bulkhead 112 that is oppositely arranged of described front bulkhead 111 and be connected sidewall 113 between described front bulkhead 111 and the aft bulkhead 112.The front group of earphone case 110 inside is equipped with loudspeaker monomer 120, and the sound that this loudspeaker monomer 120 sends passes through the front bulkhead 111 of earphone case 110 to external communication.Be formed with a resonant cavity S10 between the rear portion of loudspeaker monomer 120 and earphone case 110, this resonant cavity S10 is used to change the sound that loudspeaker monomer 120 sends, thus the feature of the sound that adjustment earphone 100 is sent.

Offer a plurality of sound regulating holes 114 on the earphone case 110, make resonant cavity S10 communicate with the extraneous space of earphone 100.Empirical tests, the difference of aspects such as sound regulating hole 114 quantity, shape, size designs can make earphone 100 have different sound performances, therefore in actual applications, can be according to different demands and quantity, shape and the size of flexible design sound regulating hole 114.In the present embodiment, the quantity of the sound regulating hole of being offered 114 is four, and regulates opening or sealing of sound regulating hole 114 for the ease of unified, and sound regulating hole 114 is on the rear wall 112 that a horizontally-arranged is arranged on earphone case 110.Pivot dress hole 115 is offered in sound regulating hole 114 belows of earphone case 110, in order to install described adjusting device 130.

Adjusting device 130 comprises that one adjusts button 131, a shielding plate 132 and a connecting rod 133, wherein, this adjustment button 131 is assembled on the lateral surface of rear wall 112 of earphone case 110, this shielding plate 132 is assembled on the medial surface of rear wall 112 of earphone case 110, this connecting rod 133 passes described pivot dress hole 115, is connected and fixed this adjustment button 131, shielding plate 132 respectively.When the adjustment button 131 of turn adjusting device 130, drive shielding plates 132 by connecting rod 133 and rotate synchronously, shielding plate 132 will block described sound regulating hole 114.

Seeing also Fig. 4,5,6, is the lateral side view of the utility model earphone 100 shown in Fig. 4,5,6.Corresponding to four sound regulating holes 114 offering on the earphone case 110, the adjustment button 131 of adjusting device 130 is provided with " 1 ", " 2 ", " 3 ", " 4 " four gears.When adjusting the above-mentioned gear of button 131 whizs, the utility model earphone 100 is an open earpiece, and when adjusting button 131 and rotate to " 1 " retaining, 132 pairs of sound regulating holes 114 of shielding plate block, and makes this sound regulating hole 114 change closed state into by open mode.When adjustment button 131 rotated to " 2 ", " 3 ", " 4 " retaining respectively, shielding plate 132 covered two, three or whole four of described sound regulating hole 114 respectively.When whole sound regulating hole 114 cresteds, earphone 100 changes the closed type earphone into.

See also Fig. 7, what this figure was represented is when shielding plate 132 covers the sound regulating hole 114 of different numbers, the variation of the frequency curve of the sound that the utility model earphone 100 is sent.This figure has intercepted the frequency range of human auditory system, and (in the 20Hz～20KHz), the utility model earphone 100 is in sound regulating hole 114 reflection to sound during at different shielding status.As shown in the figure, curve I is sound regulating hole 114 frequency curve when all not covering, and curve II, III, IV are respectively the curve of shielding plate 132 when covering one, two and whole four sound regulating holes 114.By this curve chart as seen, the utility model earphone is clearly more demarcated through the difference of adjusting device 130 adjusted each wave bands of frequency curve, high frequency is more outstanding, low frequency is finer and smoother, the sound performance is also better, and can have the sound of different characteristics to show, therefore, the utility model earphone can satisfy different users's multiple demand.

Above embodiment is only in order to illustrate principle of the present utility model.Aforementioned adjustment button 131 is to utilize may command hop count or the adjustable structure of the section of nothing to carry out the displacement adjustment, drives shielding plate 132 and blocks sound regulating hole 114.When actual design was made, the number of the sound regulating hole 114 of earphone can increase and decrease according to actual conditions, and the gear number of adjusting button 131 also can change to some extent with the increase and decrease of sound regulating hole 114 numbers.The concrete form of shielding plate 132 can be a baffle arrangement, also can be gear stick structure or other shape and structure, even can set up a plurality of shielding plates to control opening and closure of a plurality of sound regulating holes 114 as required.
