In the utility model, unless otherwise clearly defined and limited, term " installation ", " connected ", " connection ", " Gu It is fixed " etc. term should be interpreted broadly, for example, it may be being fixedly connected or being detachably connected, or be integrally connected；Can To be mechanical connection or be electrically connected；It can be directly connected, can also be indirectly connected by intermediary, Ke Yishi Connection inside two elements.For the ordinary skill in the art, above-mentioned term can be understood as the case may be Concrete meaning in the utility model.Term as used herein " and/or " include one or more relevant Listed Items Arbitrary and all combination.

Please refer to Fig.1 and Fig. 2, the earphone 100 that the embodiment of the utility model proposes, including auricular concha 10 and arranged on institute The cover 20 on auricular concha 10 is stated, loudspeaker 30, one end peace of the cover 20 away from the auricular concha 10 are fixed with the cover 20 Equipped with ear muff 40.

Fig. 2 and Fig. 3 is referred to, the ear muff 40 is equipped with ear muff tuning portion 41, and the cover 20 is equipped with cover tuning Portion 21, specifically, the cover tuning portion 21 include cover sound regulating hole 211 and above the cover sound regulating hole 211 the One groove 212, the ear muff tuning portion 41 include 411 and second groove 412 of ear muff sound regulating hole.

Specifically, first groove 212 has the first end 2121 and second end 2122 being oppositely arranged, the ear muff tune Sound hole 411 is set close to the first end 2121, and the cover sound regulating hole 211 is set close to the second end 2122.

Fig. 2 to Fig. 4 is referred to, the internal diameter of the ear muff sound regulating hole 411 is more than the internal diameter of the cover sound regulating hole 211.

First groove 212 can be integrally formed with the cover sound regulating hole 211, the axis of the ear muff sound regulating hole 411 The axle center of the heart and the cover sound regulating hole 211 shifts to install in vertical direction.

Second groove 412 is arranged on the top of the ear muff sound regulating hole 411, and second groove 412 and the ear Set sound regulating hole 411 communicates.Specifically, second groove 412 can be integrally formed with the ear muff sound regulating hole 411.Described One groove 212 is communicated with the ear muff sound regulating hole 411 and the cover sound regulating hole 211 respectively.

Specifically, the ear muff sound regulating hole 411 is located at the centre position of second groove 412.

In the present embodiment, first groove 212 and second groove 412 are oval.

Since the second groove 412 of the top of ear muff sound regulating hole 411 is oval, and the second groove 412 is in concave configuration, this Sample ear muff sound regulating hole 411 will not be blocked by auricle, be further ensured that tonequality will not be impacted.

And the first groove 212 of the top of cover sound regulating hole 211 is oval, and the first groove 212 is in concave configuration, so Ear muff 40 is effectively avoided to block cover sound regulating hole 211, while cover sound regulating hole 211 and ear muff sound regulating hole 411 when touching cover 20 It is not located on same axle center, material is thus formed one of bending channel, adds electrostatic climbing distance.

In addition, as a specific example, the diameter of the short axle of first groove 212 is more than the cover sound regulating hole 211 internal diameter.

The diameter of the short axle of second groove 412 is more than the internal diameter of the ear muff sound regulating hole 411.

And the diameter of the major axis of first groove 212 is more than the internal diameter of the cover sound regulating hole 211 and the ear muff tune The sum of internal diameter of sound hole 411.

The utility model proposes earphone 100, due to ear muff sound regulating hole 411 and cover sound regulating hole 211 in vertical direction Shift to install, i.e., ear muff sound regulating hole 411 is not located on same axle center with cover sound regulating hole 211, and the top of cover sound regulating hole 211 is set There is the first groove 212, ultimately form curved tuning passage together, add electrostatic climbing distance, weaken electric stress, And then electrostatic has been blocked in the cover external world, since the earphone is while electrostatic problem is solved, remain ear muff sound regulating hole 411 With cover sound regulating hole 211, therefore tonequality will not be damaged, in addition, the earphone can be solved effectively without additionally increase Anti-static device Certainly electrostatic problem, therefore cost is relatively low.

In the description of this specification, reference term " one embodiment ", " some embodiments ", " example ", " specifically show The description of example " or " some examples " etc. means specific features, structure, material or the spy for combining the embodiment or example description Point is contained at least one embodiment or example of the utility model.In the present specification, to the schematic table of above-mentioned term State and may not refer to the same embodiment or example.Moreover, particular features, structures, materials, or characteristics described can be Combined in an appropriate manner in any one or more embodiments or example.
