Specific embodiment
Refering to Fig. 1, Fig. 2 and Fig. 3, one embodiment of the Trackpad of present invention tool decrease of noise functions includes a lower plate list
First 1, upper plate unit, 2, trigger elements 3 and a noise reduction components 4.
The lower plate unit 1 includes a lower plate body 11 and one is connected to the lower plate body in a manner of integrally formed
11 lower articulated part 12.There are one lower inner surfaces 111 and one to be arranged at 111 one side of lower inner surface for lower plate body 11 tool
And in contrast to the lower end edge portion 112 of the lower articulated part 12.There are six pivoted holes 121 for the lower tool of articulated part 12.
The upper plate unit 2 and the lower plate unit 1 are separately and Chong Die, and including 21, glass back plates of a circuit board
22nd, a load-bearing part 23 and a upper articulated part 24 being mutually articulated with the lower articulated part 12 for being used to carry the circuit board 21.
There are one the upper inner surface 211, one towards the lower inner surface 111 is upper in contrast to the upper inner surface 211 for the circuit board 21 tool
Outer surface 212 and a upper end edge portion 213 in contrast to articulated part on this 24 and compared with the lower end edge portion 112.The upper edge
Portion 213 be arranged at 211 one side of upper inner surface and can become compared with the lower end edge portion 112 close or remote from.The glass back plate 22 is glutinous
It is affixed on the upper outer surface 212.The load-bearing part 23 is positioned at the upper inner surface 211, and articulated part 24 is connected to the load-bearing part 23 on this
And with three metal clips 241.Each metal clips 241 corresponds to two of which pivoted hole 121 and is respectively pivoted to corresponding
Pivoted hole 121.
The trigger element 3 includes a relief in the touch switch 31 of the upper inner surface 211 and one compared with the shake-up
Switch 31 and relief in the touch part 32 of the lower inner surface 111.There are one periphery 311 and a settings for the touch switch 31 tool
Striking portion 312 in the periphery 311.During the 213 convergence lower end edge portion 112 of upper end edge portion, the striking portion 312 and the shake-up
Part 32 contacts and triggers the touch switch 31.It should be noted that the touch switch 31 and the touch part 32 in the present embodiment
Relief is in the upper inner surface 211 and the lower inner surface 111 respectively, but the touch switch 31 and the touch part 32 can also be point
Other relief is in the lower inner surface 111 and 211 (not shown) of upper inner surface.
The noise reduction components 4 are enclosed around shape outside the touch switch 31 in hollow ring, and stick in the circuit board 21, and by
The lower inner surface 111 of the upper inner surface 211 of the upper plate unit 2 towards the lower plate unit 1 extends.The noise reduction components 4 include an energy
Defining the 41, outer rims 42, one in contrast to the inner edge 41 in inner edge of an endoporus 411, to be connected to the inner edge 41 outer with this
Inner face 43 and an outer end face 44 in contrast to the inner face 43 between edge 42.The outer rim 42 and the distance of the inner edge 41
Between 2 to 5 millimeters, in the present embodiment, the outer rim 42 and the distance of the inner edge 41 are essentially 3 millimeters.The trigger switch
31 striking portion 312 is stretched in the endoporus 411, and the position in the striking portion 312 is located at the inner face 43 and the outer end face 44
Between, which compels tightly to contact at the periphery 311 of the touch switch 31.The periphery 311 of the touch switch 31 is between this
Between the inner edge 41 of noise reduction components 4 and outer rim 42.4 material of noise reduction components is foam, and the upper end edge portion 213 is away under this
During end edge portion 112,44 convergence of outer end face or stick in the lower inner surface 111 (state as shown in Figure 3), and the upper end edge portion
During 213 convergence lower end edge portion 112, which is compressed, which compels tightly to stick in the lower inner surface 111
(not shown).The noise reduction components 4 need simple and directly stick in the circuit board 21 during due to assembling, indirectly so that this hair
Bright cost reduction.
From the point of view of further, when the sound wave Producing reason of noise is that the touch switch 31 is triggered caused by sky
Gas vibrates.When the touch switch 31 is triggered and when generating noise, since the noise reduction components 4 are compressed, and the outer end face 44 is compeled
Tightly stick in the lower inner surface 111, thus the noise reduction components 4 by source of sound be closed in the endoporus 411, the upper inner surface 211 with
In the space that the lower inner surface 111 defines jointly, and compel tightly to contact at the periphery 311 using the inner face 43 and inhibit should
The vibration of touch switch 31 so that the frequency of vibration reduces.When sound wave is by the noise reduction components 4, the resistance of air vibration is added
Power, and the intensity of vibrations is reduced.Sound wave as the aforementioned generates and transmittance process, caused by preferably reducing the present invention
High frequency noise.Further, since the sound wave reflected is transferred still in the space of closing and constantly absorbed, and have preferably every
Audio fruit.Via experimental measurement, the noise average out to 65 for being generally not provided with the Trackpad institute striking generation of the noise reduction components 4 divides
Shellfish, and the Trackpad of present invention tool decrease of noise functions can be reduced the noise of striking to 45 decibels, while high frequency section is also effectively
Attenuation 40%.
In conclusion the Trackpad of present invention tool decrease of noise functions can reduce high frequency noise by the setting of the noise reduction components 4,
The noise reduction components 4 also can be assembled simply and directly simultaneously, cause the cost reduction of the present invention indirectly, so can reach this really
The purpose of invention.
