Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-4 is please referred to, the utility model provides a kind of technical solution: a kind of high-fidelity headphone with noise reduction, including
Rear cover 1 is fixed with sound deadening sheet 2 inside rear cover 1, and 1 rear of rear cover is fixed with connection shell 11, is connected with positioning in front of sound deadening sheet 2
Block 3, and baffle 9 is fixed with inside sound deadening sheet 2, and sound deadening sheet 2 is externally connected to barney 10 is inside sound deadening sheet 2
Hollow structure, and sound deadening sheet 2 uses elastic sponge material, the sound deadening sheet 2 of this structure plays the role of sound insulation, inside sound deadening sheet 2
Hollow structure can sponge most of noise, reduce propagation of the noise inside the device, tie inside baffle 9 for perforation
Structure, and it is evenly distributed in 2 hollow structure of sound deadening sheet, and 9 quantity of baffle is three, the baffle 9 of this structure can be with
Noise is reflected, noise is reflected can inside sound deadening sheet 2, to reduce the energy inside noise, plays absorption noise
Effect, and the perforation structure inside baffle 9 facilitates the circulation of air, prevents from being extruded appearance inside sound deadening sheet 2 damaged
The case where, fixed link 4 is installed outside locating piece 3, and fixed link 4 is externally connected to rear cover 1, is cylindrical outside locating piece 3
Structure, and its center line and 2 center line of sound deadening sheet are on the same line, and the height of locating piece 3 is greater than 4 thickness of fixed link
Degree, the locating piece 3 of this structure can inwards push up sound deadening sheet 2, and 2 surface of sound deadening sheet is made to form concave-convex shape, improve and absorb
The effect of noise, connection 11 lower end of shell is fixed with connecting line fixing piece 5, and 5 lower end of connecting line fixing piece is equipped with connecting line 6,
And connecting line 6 is externally connected to plug 7, phonation unit 8 is fixed with inside barney 10, and be fixed with outside phonation unit 8
Shell 11 is connected, and connects shell 11 and is externally connected to silica gel ear muff 12, remote 2 end of sound deadening sheet of barney 10 is groove structure, and every
Sound covers 10 groove structure interior shapes, 2 end outer shape of sound deadening sheet close with phonation unit 8 and matches, and barney 10 is using more
The barney 10 of hole sponge material, this structure can wrap nearly 2 end of sound deadening sheet of phonation unit 8, make phonation unit 8 reduce by
To external influence, and the porous structure inside barney 10, play the role of absorbing remaining noise, improves the drop of the device
It makes an uproar effect.
Working principle: when having the high-fidelity headphone of noise reduction using this, plug 7 is first fixed to extraneous player
In, then the silica gel ear muff 12 connected on shell 11 is fixed in ear again, so that rear cover 1 is in the outside of ear, then makes
During, phonation unit 8 is made a sound by connecting line 6, is then transmitted to sound in ear by silica gel ear muff 12,
If there is bigger noise in the external world, extraneous noise can be transmitted on rear cover 1, and then sound deadening sheet 2 can sponge noise
Most of, such noise can be reflected under the action of baffle 9 in sound deadening sheet 2, and the noise of absorption is consumed with this
Energy, noise reduction is achieved the effect that with this, and remaining noise can be sponged by cavernous barney 10, make sounding list
