First cylinder 310 may include material identical with hollow shaft 100, and the second cylinder 330 may include and outer thin The identical material of piece 200, to improve the fixed characteristic of the first cylinder 310 and the second cylinder 330.In addition, 310 He of the first cylinder Second cylinder 330 may include material identical with disk body 320, effectively to absorb external force and noise.In this case, flexible Component 300 may include that have durometer hardness be about 10 ° to about 70 ° of silicon rubber.

Specifically, the first groove 131 can be set together and the second groove 201 with the second end 102 of hollow shaft 100 It can be set together with the inside of exterior sheet 200.

First groove 131 can have can from the first depth d1 of the outer surface depressions of ontology 130 and with the first cylinder 310 The corresponding first length l1 of height h1.First groove 131 may be arranged at the exterior circumference of the second end 102 of hollow shaft 100 On surface.Second groove 201 can have can from the inner surface of exterior sheet 200 be recessed the second depth d2 and with the second cylinder The corresponding second length l2 of 330 height h2.Second groove 201 may be arranged on the inner circumferential surface of exterior sheet 200.

Therefore, the first cylinder 310 is positively retained in the first groove 131 and can be tightly fastened by interference engagement to hollow The ontology 130 of axis 100, and the second cylinder 330 is positively retained in the second groove 201 and can be fixed to by interference engagement outer Portion's thin slice 200.Therefore, the first cylinder 310 and the second cylinder 330 can be individually secured to hollow shaft 100 and exterior sheet 200, As sealing ring.Annular disk body can be integrally connected to the first cylinder 310 and the second cylinder 330, and can be in radial direction r Upper extension.It therefore, can be from the sufficiently sealed air gap G of ambient enviroment.

Although this illustrative embodiment disclose the first cylinder 310 and the second cylinder 330 to be positively retained at first respectively recessed In slot 131 and the second groove 201, with for being fixed to hollow shaft 100 and exterior sheet 200, but the first cylinder 310 and second Cylinder 330 can be directly fixed to the original form of hollow shaft 100 and exterior sheet 200 in the case where no groove, as long as can Relative to the sufficiently sealed air gap G of ambient enviroment.

In the illustrative embodiments of modification, the first cylinder 310 can be fixed to hollow shaft by first adhesive 410 100, and the second cylinder 330 can be fixed to exterior sheet 200 by second adhesive 420.

A variety of jointing materials be can use as first adhesive 410 and second adhesive 420, as long as flexible member 300 Hollow shaft 100 and exterior sheet 200 can be still sufficiently adhering under conditions of external force.For example, silicon adhesive can be in the first groove Be arranged between the first cylinder 310 and hollow shaft 100 in 131, and in the second groove 201 setting the second cylinder 330 with it is outer Between portion's thin slice 200.

It can be arranged under flexible member using air pressure according to above-mentioned eartip 500, the air gap G full of air, so that gas Air in gap G can sufficiently resist the external force that may be applied to exterior sheet.Accordingly it is possible to prevent exterior sheet is due to air gap G Air pressure caused by distortion caused by external force or deformation, and although external force applies so far, eartip can still remain former Beginning shape.In addition, flexible member can be individually secured to hollow shaft and exterior sheet, so that exterior sheet can be substantially prevented from in Empty axis separation, and therefore prevent from overturning due to the axial force along hollow shaft.In addition, when flexible member may include having It, can be by external noise and gravitational attraction into flexible member, to make to pass through when the relatively low soft material or ductile material of hardness Minimizing deformation caused by external force and improve the sound quality in user's ear.

In view of the use environment of earphone, the various modifications of above-mentioned eartip 500 are allowed.

Fig. 2A and Fig. 2 B is to show the sectional view of the first modification of the eartip shown in fig. ib.In addition to for controlling Except the pressure controller of the air pressure of air gap G processed, the eartip 501 of the first modification has and ear shown in Figure 1A and Figure 1B 500 basically same structure of machine end.As shown in Figure 2 A, it may be provided in as pressure controller pressure hole APH in flexible member At 300, or as shown in Figure 2 B, it is arranged at exterior sheet 200.

With reference to Fig. 2A and Fig. 2 B, pressure hole APH can be arranged at least one of exterior sheet 200 and flexible member 300 Together.Because air gap G can be limited by hollow shaft 100, exterior sheet 200 and flexible member 300, and be used for transmission audio letter Number sound conduit C may be provided with hollow shaft 100, the hole of hollow shaft 100 will make the sounds quality degradations of sound conduit C.Therefore, Pressure hole APH may be provided at least one of exterior sheet 200 and flexible member 300 place, so as not to make sounds quality degradations.
