Specific implementation mode
Refering to fig. 1, Fig. 2 and Fig. 3, the utility model has one embodiment of the Trackpad of decrease of noise functions, including under one
The trigger element 3 of upper plate unit 2, one of plate unit 1, one and a noise reduction components 4.
The lower plate unit 1 includes that a lower plate body 11 and one are 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 set to 111 side of lower inner surface for the lower plate body 11 tool
And in contrast to the lower end edge portion of the lower articulated part 12 112.There are six pivoted holes 121 for the lower articulated part 12 tool.
The upper plate unit 2 and the lower plate unit 1 are separately and Chong Die, and include 21, glass back plates of a circuit board
22, a load-bearing part 23 and a upper articulated part 24 being mutually articulated with the lower articulated part 12 for carrying 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 one are in contrast to articulated part on this 24 and relative to the upper end edge portion of the lower end edge portion 112 213.The upper end
Edge 213 be set to 211 side of upper inner surface and can become relative to the lower end edge portion 112 close or remote from.The glass back plate 22
Stick in 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 on this
23 and have three metal clips 241.Each metal clips 241 corresponds to two of which pivoted hole 121 and is respectively pivoted to correspondence
Pivoted hole 121.
The trigger element 3 is including a relief in the touch switch 31 of the upper inner surface 211 and one relative to the shake-up
Switch 31 and relief are 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.When the upper end edge portion 213 approaches the lower end edge portion 112, 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 in the present embodiment and the touch part 32
Relief is in the upper inner surface 211 and the lower inner surface 111 respectively, but the touch switch 31 can also be with the touch part 32
Relief is in the lower inner surface 111 and 211 (not shown) of upper inner surface respectively.
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
Outer rim 42, one of the inner edge 41, one in contrast to the inner edge 41 for defining an endoporus 411 is connected to the inner edge 41 and is somebody's turn to do
Inner face 43 between outer rim 42 and an outer end face 44 in contrast to the inner face 43.The outer rim 42 and the inner edge 41 away from
From between 2 to 5 millimeters, in the present embodiment, which is essentially 3 millimeters at a distance from the inner edge 41.The shake-up is opened
The striking portion 312 of pass 31 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
Between 44, which compels tightly to contact at the periphery 311 of the touch switch 31.The periphery 311 of the touch switch 31 between
Between the inner edge 41 and outer rim 42 of the noise reduction components 4.4 material of noise reduction components is foam, and the upper end edge portion 213 is away from this
When lower end edge portion 112, which approaches or sticks in the lower inner surface 111 (state as shown in Figure 3), and the upper end
When edge 213 approaches the 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 when due to assembling, make indirectly
The cost reduction of the utility model.
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 when generating noise, since the noise reduction components 4 are compressed, and the outer end face 44 is compeled
It tightly sticks in the lower inner surface 111, so source of sound is closed in the endoporus 411, the upper inner surface 211 by the noise reduction components 4
In the space defined jointly with the lower inner surface 111, and compel tightly to contact at the periphery 311 and inhibit using the inner face 43
The vibration of the touch switch 31 so that the frequency of vibration reduces.When sound wave is by the noise reduction components 4, air vibration is increased
Resistance, and the intensity of vibrations is reduced.Sound wave as the aforementioned generates and transmittance process, preferably reduces the utility model institute
Caused by high frequency noise.In addition, since the sound wave reflected transmits still in closed space and is constantly absorbed, and have compared with
Good soundproof effect.Via experimental measurement, the noise average out to that the Trackpad institute striking of the noise reduction components 4 generates is not set generally
65 decibels, and the Trackpad of the utility model tool decrease of noise functions can be reduced the noise of striking to 45 decibels, while high frequency section
Also effectively decay 40%.
In conclusion the Trackpad of the utility model tool decrease of noise functions can reduce high frequency by the setting of the noise reduction components 4
Noise, while the noise reduction components 4 also can be assembled simply and directly, make the cost reduction of the utility model indirectly, so really
It can reach the purpose of this utility model in fact.
