Specific embodiment

In the following description, for purposes of illustration, in order to provide the comprehensive understanding to one or more embodiments, explain Many details are stated.It may be evident, however, that these embodiments can also be realized in the case of without these details. In other examples, for the ease of describing one or more embodiments, known structure and equipment show in block form an.

To describe the structure of the sound tube adjustable angle earphone of the utility model embodiment in detail, below with reference to accompanying drawing pair Specific embodiment of the utility model is described in detail.

Fig. 1 shows the cross-section structure according to sound tube adjustable angle earphone of the present utility model；Fig. 2 is shown according to this The overall structure of the sound tube adjustable angle earphone of utility model.

As Fig. 1 and Fig. 2 jointly shown in, sound tube adjustable angle earphone of the present utility model, including adaptation connection protecgulum 4 With bonnet 1, the horn single body being housed in protecgulum 4 and bonnet 12；It is embedded with the inner surface of protecgulum 4 and is mutually fitted with the structure of protecgulum 4 With and with the inner cap 3 that is flexibly connected of protecgulum 4, one end of inner cap 3 is fixedly connected with horn single body 2, is set in the other end of inner cap 3 It is equipped with sound tube 5；The breach 42 for extending is provided with the position of the correspondence sound tube 5 of protecgulum 4, inner cap 3 can be in the inward turning of protecgulum 4 Turn, the adjustment angle in breach 42 of sound tube 5, different user can be according to wearing the angle of custom and comfort level to sound tube 5 Degree is adjusted.

Specifically, the diameter of the breach 42 of protecgulum 4 is set greater than the diameter of sound tube 5, can allow for sound tube 5 at this Adjustment angle in breach 42, sound tube 5 can be in breach 42 it is arbitrarily angled between switch, its rotatable maximum angle with The diameter of breach 42 is related.

Additionally, to simplify earphone packaging technology, it is ensured that the firmness that sound tube 5 is connected with inner cap 3, in the utility model In embodiment, sound tube 5 can be set with inner cap 3 and be structure as a whole, when 5 angle of sound tube is adjusted, inner cap 3 drives loudspeaker Monomer 2 is rotated in protecgulum 4.

In sound tube adjustable angle earphone of the present utility model, protecgulum 4 is similar semicircle knot with the structure of bonnet 1 Structure, connection between protecgulum 4 and bonnet 1 can be using fastening or the various ways such as be threadedly coupled.For example, working as protecgulum and bonnet When being fixedly connected using manner, the first buckling parts 41 of projection can be provided with protecgulum 4, in the correspondence of bonnet 1 first The position of buckling parts 41 sets corresponding second buckling parts 11；It is real by the first buckling parts 41 and the fastening of the second buckling parts 11 The connection of existing protecgulum 4 and bonnet 1.Alternatively, it is also possible to the screw thread that the position being combined in protecgulum and bonnet, setting are mutually matched, Protecgulum and bonnet tighten fixation by screw thread.

During sound tube angular adjustment, for the acoustical behavior for ensuring earphone keeps stabilization, of the present utility model another In one specific embodiment, restricted inner cap 3 is set along the spacing of the axis direction movement of horn single body 2 in the inner side of protecgulum 4 Structure (not shown), the axial direction of horn single body 2 is in the axis direction of the vibrating diaphragm of horn single body 2 or voice coil loudspeaker voice coil Axis direction, is able to ensure that inner cap 3 fits with protecgulum 4 all the time in rotary course by position limiting structure, it is to avoid protecgulum 4 with it is interior Lid 3 is separated.

In addition, the cavity that inner cap 3 and bonnet 1 are formed is divided into the preceding operatic tunes and the rear operatic tunes, horn single body 2 by horn single body 2 The preceding operatic tunes is formed with inner cap 3, the preceding operatic tunes is turned on sound tube 5；The operatic tunes after horn single body 2 and the formation of bonnet 1, the rear operatic tunes is closed Structure, is only turned on by damping hole or rear acoustic aperture with extraneous, realizes the air pressure balance of the preceding operatic tunes and the rear operatic tunes.When inner cap 3 exists In protecgulum 4 during rotation, the volume of the rear operatic tunes keeps constant, so that it is guaranteed that the acoustical behavior stabilization of the adjustable angle earphone of sound tube 5.

In another specific embodiment of the present utility model, horn single body 2 includes vibrational system and magnetic circuit system；Its In, vibrational system includes the voice coil loudspeaker voice coil of vibrating diaphragm and combination in vibrating diaphragm side；Magnetic circuit system include combine successively washer, magnet and Conductive magnetic yoke, magnetic gap is formed between the side wall and washer and magnet of conductive magnetic yoke, and voice coil loudspeaker voice coil is hung in magnetic gap.

Specifically, the magnetic circuit system of horn single body 2 could be arranged to single magnetic structure or two magnetic route structure；When magnetic circuit system Unite during for two magnetic route structure, magnet includes centring magnet and the side magnet set around centring magnet, washer is included respectively with Heart magnet and while the corresponding center washer of magnet and while washer；Centring magnet and center washer and while magnet and while washer between shape Into magnetic gap, voice coil loudspeaker voice coil is hung in magnetic gap, when the voice coil loudspeaker voice coil in magnetic field has tone currents to flow through, can be subject to an alternation Motive force produces alternate motion, so as to drive vibrating diaphragm to shake, and then promotes air repeatedly and sounding.

In the assembling process of the sound tube adjustable angle earphone of the utility model embodiment, horn single body 2 is filled first It is assigned on inner cap 3, horn single body 2 is fixedly connected to form preceding acoustic cavity portion with inner cap 3；Then, will assemble in horn single body 2 Lid 3 is assembled in protecgulum 4, and inner cap 3 free angle can be rotated in protecgulum 4；Finally, bonnet 1 is assembled with protecgulum 4, Acoustic cavity portion after formation, earphone packaging technology simplifies, while being able to ensure that the assembling quality and acoustical behavior of earphone.

Furthermore it is also possible to set the pleasant gum cover of adaptation connection and the acoustics of regulation horn single body 2 on sound tube 5 The tuning sheet material of energy；Wherein, tuning sheet material is using screen cloth, sponge or non-woven fabrics etc.；Pleasant gum cover can use silica gel or height The materials such as elastic polyester are made, its insert duct after can be in close contact with duct, with completely cut off sound into middle ear with In inner ear, the purpose of sound insulation is reached.

The sound tube adjustable angle earphone of the utility model embodiment, also including earphone cord, one end of earphone cord and loudspeaker Monomer is turned on, and the other end of earphone cord is provided with the plug turned on exterior terminal equipment (or external portable electronic product).

The sound tube adjustable angle earphone that the utility model is provided can be seen that by above-mentioned implementation method, using inner cap Can in protecgulum free angle rotate characteristic, enable sound tube that the voluntarily tune of angle is carried out according to the different ducts of user Whole, from being brought into close contact for sound tube and duct is ensured, allow earphone wears is more comfortable.

Described in an illustrative manner according to sound tube adjustable angle earphone of the present utility model above with reference to Fig. 1 and Fig. 2.But It is, it will be appreciated by those skilled in the art that the sound tube adjustable angle earphone proposed for above-mentioned the utility model, can be with Various improvement are made on the basis of the utility model content is not departed from.Therefore, protection domain of the present utility model should be by institute The content of attached claims determines.
