Embodiment

For clearly demonstrating content of the present utility model, sincerely arrange in pairs or groups in the following instructions graphic, for making to be convenient to understand, the same components in following embodiment illustrates with identical symbology.

Refer to Fig. 2 to Fig. 5, it be the exploded view of the utility model preferred embodiment, the schematic diagram of stereogram, catch net and use schematic diagram.As shown in Figures 2 to 5, the earphone structure 2 of In-Ear Headphones of the present utility model, it has two housings 21, a loud speaker 22 is provided with in this each housing 21, and this each housing 21 one end has extended to form a sender 214, the sound wave spread out of from this loud speaker 22 has been enable to have enough organ for resonance to produce sufficient sympathetic response like this.

Of the present utility modelly to be characterised in that: this each housing 21 is by a fore shell 211, one inner casing 212 and a back cover 213 formed, this inner casing 212 is fixed in this back cover 213 and this fore shell 211 and this back cover 213 are formed closed, this loud speaker 22 is connected with this inner casing 212, this sender 214 is located on this fore shell 211, and the outer surface of this back cover 213 is more provided with an installing hole 215, this installing hole 215 is not in relative position with this sender 214, a vibrational structure 23 corresponding with this installing hole 215 shape this installing hole 215 be equipped with, this vibrational structure 23 contacts with the auricular concha 3 of ear, this vibrational structure 23 has vibrating diaphragm sheet 231 and an extensible member 232, this vibrating diaphragm sheet 231 is fixedly arranged on this extensible member 232, the material of this vibrating diaphragm sheet 231 is thin metal, and the material of this extensible member 232 is flexible material, when the sound wave sent from this loud speaker 22 is in described housing 21 internal vibration, this extensible member 232 and this vibrating diaphragm sheet 231 can pass through along with sound wave and vibrate thereupon, and the sound wave do not spread out of from this sender 214 is spread out of by this vibrational structure 23.

In use, earphone structure 2 made by the utility model is filled in duct by user, built-in this loud speaker 22 of earphone structure 2 starts to play music, music is from after this loud speaker 22 sends and constantly vibrates the closed organ for resonance that rear elder generation formed at this fore shell 211 and this back cover 213, and the sound wave of most of music can spread out of directly to reach ear-drum from this sender 214 and ear-drum be vibrated allow user hear play music thereupon.And this vibrational structure 23 that the sound wave of remainder music is installed from this installing hole 215 outwards broadcasts.

Again, this vibrational structure 23 go out sound direction can with this sender 214 go out the angle that sound direction accompanies 30 degree to 120 degree, be denoted as θ in figure 3, preferably, is illustrated in figure 3 85-90 degree or 90-95 degree, but not as limit, different according to this housing 21, folded by it, angle is also different.So this vibrational structure 23 go out the scope that auricular concha 3 that sound direction is positioned at ear contains, if exceed outside this angular range, the sound wave spread out of from this vibrational structure 23 just almost cannot again received by user, and this vibrational structure 23 designed by the utility model can contact with the auricular concha 3 of ear, so the sound wave spread out of via this vibrational structure 23 can be transmitted by auricular concha 3 and again reach ear-drum.And by the air sound wave transmitted and the sound wave transmitted by human body, in acoustically having difference, and then strengthening the effect of bass, just can bring user different pleasures of the senses.Simultaneously because part sound wave spreads out of from this vibrational structure 23, so the moment impact suffered by ear-drum just can reduce effectively, and then reduce the ear-drum of sense of discomfort user impacts to(for) sound wave.

In addition, on this installing hole 215, cover has a catch net 24, and this material such as vibrating diaphragm sheet 231 or oil stain remained on hand, sweat that this catch net 24 prevents dust from touching this vibrational structure 23 touches this vibrating diaphragm sheet 231 or this extensible member 232.If this vibrating diaphragm sheet 231 or this extensible member 232 speckle with the words of oil stain, dust or sweat, this vibrating diaphragm sheet 231 or this extensible member 232 may be made when vibrating because of the unequal reason of weight proportion, cannot produce as usual normal vibration, so can make this vibrational structure 23 cannot normal operation, and then cause the sound wave that spreads out of from this vibrational structure 23 not as expected.The material of this catch net 24 is metal; and this catch net 24 forms for the laminating that changes mutually of double layer of metal net; and the grid of this double layer of metal net is also not exclusively overlapping; the grid of this catch net entirety formed after changing mutually so more reduces; the net footpath of this catch net 24 is approximately reduced between 0.05mm to 0.1mm, allows dust is more difficult touches this vibrational structure 23.

By design so, the utility model can reach the impact reducing this loud speaker 22 pairs of ear-drums, and can again collect originally in order to reduce impact and the part sound wave that releases and again by user the effect of listening to.And let out sound hole 112 compared to the prior art shown in Fig. 1, arround can not making, crowd feels noisy or uncomfortable, because the sound wave that spread out of by this vibrational structure 23 can by the auricular concha 3 of ear for sound wave be reached ear-drum by vibration medium again, produce sensation as circulating type audio to make user.The utility model is more provided with an annular recess 216 on this fore shell 211, engages thereon for an earplug 25, allows the utility model be easier to be fixed in duct and difficult drop-off.

More than illustrate the utility model just illustrative; and it is nonrestrictive; those of ordinary skill in the art understand; when not departing from the spirit and scope that the utility model claims limit; many amendments can be made; change, or equivalence, but all will fall in protection range of the present utility model.
