Three ribs 56 are equipped with, ribs 56 are protruded into tone channel 55 along the radial direction of filtering chamber 51.
Referring to Fig. 7 and Fig. 8, wave filter 2 has sound mouth 21, into sound mouth 22, chamber 24, housing 23, identification pattern 25.And
Wave filter 2 is manufactured so that it possesses corrosion-resistant, non-friable and durable characteristic and is convenient for processing by using metal material
Production, and work as the earplug for being equipped with earplug filtering fuse once falling on the ground, can be by using equipment such as such as metal detectors
To recover.
Referring to Fig. 7, when from being carried out from 2 lower end of wave filter with the visual angle looked up to wave filter 2, sound mouth 21 is formed in
In chamber 24, the cross-sectional area of sound mouth 21 is less than the cross-sectional area into sound mouth 22.
Referring to Fig. 8, the shape of earplug body 3 can be determined according to different use environments, in the present embodiment, earplug body 3
Oriented duct extension convex block is set, wave filter 2 is placed in earplug body 3, and two end faces of wave filter 2 with earplug body 3
External world's connection, so that sound wave enters in wave filter 2.The both ends of the surface of wave filter 2 can be directly exposed to the end face of earplug body 3
On, it can also be connected with a passage in earplug body 3, the other end of the passage is extended on the end face of earplug body 20.
The chamber 24 that is internally formed certain depth of the chamber 24 from the lower end of housing 23 to housing 23.In the present embodiment,
Shell selects cylinder, and chamber selects cylindrical cavity, the length in the axial direction of housing 23 it is bigger 0.2mm than the depth of chamber 24 or with
On.Sound mouth 21 is formed in the upper end of housing 23, the lower end of chamber 24 is formed into sound mouth 22.
The periphery wall of housing 23 formed with identification pattern 25, identification pattern 25 to the size of the cross-sectional area of sound mouth 21 into
Line identifier.In the present embodiment, used identification pattern 25 is two annulus, and two annulus are mutual on the longitudinal direction of housing
Parallel, identification pattern 25 is arranged to circumferentially extend to 23 periphery wall of housing, and the number of rings of identification pattern 25 can be according to going out sound
The size of mouthful cross-sectional area and select varying number, such as when the cross-sectional area of sound mouth 21 is different by size and it is transversal to be divided into first
When area, the second cross-sectional area, the 3rd cross-sectional area etc., the number of rings of identification pattern 25 can correspond to selection one respectively
Bar, two, three etc..And mainly it is subject to sound mouth horizontal since the high frequency noise of the wave filter 2 in the utility model weakens function
The influence of sectional area, therefore the identification pattern 25 that cross-sectional area size is identified also is played and is made an uproar to the high frequency of wave filter 2
Sound weakens the effect that the power of function is identified.
In addition, on the one hand because the location dimension of sound mouth 21 and the dimension precision requirement of form dimension are higher, the opposing party
Face is because the small volume of wave filter 2 causes processing inconvenience, so that in the present embodiment, sound mouth 21 passes through cold laser processing side
Method and be made to ensure that the location dimension of sound mouth 21 and the dimensional accuracy of form dimension are met the requirements.
When external sound wave into sound mouth 21 from when entering in the chamber 24 of wave filter 2, high frequency sound wave is due to its weaker diffraction
Ability and cause its energy when through chamber 24 significantly to be weakened so that cause through sound mouth 21 enter human antrum auris in
Sound wave be essentially the stronger middle low-frequency range sound wave of diffracting power.
In this way, after wearing earplug, extraneous voice signal can be conducted to wave filter 2, and wave filter 2 can be effectively by high frequency
Noise attenuation, and useful middle low-frequency sound wave is sent in human antrum auris.After wearing earplug, user can still hear that the external world has
Middle low frequency sound signals, will not produce blocking sense.
Referring to Fig. 1, switch member 6 includes limited block 7, and limited block 7 is assemblied in mounting portion 143.Two ends of limited block 7
Portion, guide pad 30 and gib block 10 are respectively positioned in the sliding eye 13 of sliding part 1, simplify switch member structure, reduce production cost.Open
The limited block 7 and the limited wall 11 of sliding part 1 for closing part 6 are oppositely arranged.Gib block 10 is connected to the bearing surface 34 of fixing piece 3 with supporting
Junction 35, sliding part 1 make displacement under the action of guide pad and gib block 10, optimize the performance of ear plug 8.
The movement of limited wall 11 and limited block 7 to sliding part 1 rise position-limiting action, make user by the moving limit position of sliding part 1 and
Accurately hold the working status of switch member 6.Acoustic portion 32 is covered by sound proof part 12 to optimize the noise control filter function of switch member 6.
The top of sliding part 1 is assemblied in cavity formed with cavity, cover board 100.Cover 4 outer surface of moving magnet being assemblied in magnet chamber 50
Silica gel is stamped to slow down impact of the moving magnet 4 to switch member 1.In the present embodiment, moving magnet 4 is close to one end of limit hole 31
Polarity is arranged to the South Pole, and polarity of first magnet close to one end of limit hole 31 is the South Pole, and the second magnet is close to limit hole 31
The polarity of one end is the arctic.
When moving magnet 4 is mutually close with the second magnet, guide pad 30 is connected to limited block 7, and moving magnet 4 and fixed magnet are mutual
Attract, moving magnet 4 is moved to cylindrical hole 311 and is connected to the side of cylindrical hole 311 and the bottom of round platform hole 310.At this time, magnetic is moved
Iron 4 stops movement, and one part is protruded into round platform hole 310, and sound proof part 12 covers acoustic portion 32, and buffer action is played to sound
It is sound proof part 12, moving magnet 4 and wave filter 2.When sliding part 1 slides into guide pad 30 along gib block to be abutted with limited wall 11,
Second magnet 4 is away from moving magnet, and moving magnet 4 is close to the first magnet, and moving magnet 4 and the first magnet are mutually exclusive, and moving magnet 4 moves
To ribs 56 and it is connected to ribs 56.At this time, sound proof part 12 leaves acoustic portion 32, and sound enters tone channel by acoustic portion 32
55 and through being assemblied in filtering chamber 51 wave filter 2 filtering after enter human antrum auris.
Sliding part 1 is attracted or repelled by mobile to make two fixed magnets be realized respectively to moving magnet 4, when fixed magnet and is moved
When magnet 4 is attracting, ear plug 8 completely cuts off external sound；When fixed magnet and moving magnet 4 repel each other, external sound access switch
Filtered in part 6 and by wave filter, so as to avoid noise from entering human antrum auris.It therefore meets user is in different noisy environments
Under noise control demand.
Finally it is emphasized that the utility model is not limited to the above embodiment, the foregoing is merely the utility model
Preferred embodiment, be not intended to limit the utility model, where within the spirit and principles of the present invention, made
Any modification, equivalent substitution, improvement and etc., should be included within the scope of protection of this utility model.
