Specific embodiment

In order that technical problem, technical scheme and beneficial effect that this utility model is solved become more apparent, below In conjunction with drawings and Examples, this utility model is further elaborated.It should be appreciated that described herein be embodied as Example only in order to explain this utility model, is not used to limit this utility model.

Refering to a kind of headphone of Fig. 1 and Fig. 2, including arc headgear assemblies 10 and two earphone bodies 20, this arc head Left and right two ends with assembly 10 are respectively provided with an earphone body 20.

Refering to Fig. 3 to Fig. 4, this earphone body 20 includes first shell 30 and second shell 40, between first shell 30 and second shell 40 It is provided with buckle structure, this first shell 30 and second shell 40 snap together through buckle structure.

This first shell 30 is plastic housing, and this second shell 40 is metal-back.

Include engaging protuberances 50 and the engaging recessed part for receiving engaging protuberances 50 refering to this buckle structure of Fig. 6 to Figure 11 60, engaging protuberances 50 are on one of first shell 30 and second shell 40 part, and engaging recessed part 60 is located at first shell 30 He On another part in second shell 40, when first shell 30 is fastened with second shell 40, this engaging protuberances 50 is absorbed in engaging recessed part 60 In and be interlocked with engaging recessed part 60.

This second shell 40 is the cover body of a hollow, and this second shell 40 is placed on outside first shell 30.

This first shell 30 has lateral surface 301, and this second shell 40 has medial surface 401, and the medial surface 401 of this second shell wraps Enclose the lateral surface 301 of first shell, this engaging protuberances 50 is in first shell 30, and this engaging protuberances 50 is from the lateral surface of first shell 301 protrude to the outside of first shell 30, and this engaging recessed part 60 is in second shell 40, and this engaging recessed part 40 is from second shell Side 401 is to the inner recess of second shell 40.

This engaging protuberances 50 and engaging recessed part 60 interference fit.

This engaging protuberances 50 is a circular protrusion, and this engaging recessed part 60 is an annular recess.

This earphone body 20 also includes the case ring 70 of an aluminum alloy material, and it passes through extrusion process machine-shaping, this enforcement In, this case ring 70 uses 6061 grade aluminium alloys.

This first shell 30 is plastic cement material, and it passes through mold injection machine-shaping, and wherein this engaging protuberances 50 is in molding Molding simultaneously during first shell 30.

This second shell 40 is also aluminum alloy material, and it first passes through extrusion process machine-shaping main part, after by master Body portion uses cnc (computer numerical control Computerized digital control system) this engaging recessed part 60 of machine-shaping (i.e. annular recess).In this enforcement, this second shell 40 uses 6061 grade aluminium alloys.

The size of engaging protuberances 50 should be slightly bigger than the size of engaging recessed part 60, and both are interference fit, so can lift One shell 30 and the fastening reliability of second shell；This buckle structure design and assembly process is simple is it is not necessary to be glued using glue auxiliary Connect, improve production assembling concordance and production efficiency, reliability is high, and can be with cost efficiency.For example, engaging recessed part 60 is recessed Sunken depth is 0.17mm, and the protrusion height of engaging protuberances 50 is 0.2mm, and so, engaging recessed part 60 is had with engaging protuberances 50 The interference fit of 0.03mm.Because second shell 40 is metal material, there is not the stress cracking problem leading to because of interference fit； After second shell 40 and first shell 30 fasten and fit together, fit together second shell 40 and the being assemblied in case ring 70 On one shell 30, form the bonnet of the shell of headphone.

This utility model is simple for assembly process, and the mechanical lock of first shell 30 and second shell 40 and dynamics height are it is not necessary to use Glue auxiliary bonding, it is possible to resolve deformation, the problem of dislocation, lifting between first shell 30 and second shell 40 during assembling and use Produce assembling concordance and production efficiency, can cost efficiency.

The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all this Any modification, equivalent and improvement made within the spirit of utility model and principle etc., should be included in this utility model Protection domain within.
