Description

Technical Field

[0001] The invention relates to a module, and in particular to a noise reduction keyboard module for reducing the noise generated by tapping or pressing keys. Background Art

[0002] See also Figure 1 , Figure 2 and Figure 3 , Figure 4 As shown, they are respectively a bottom stereogram of a key (1) of an existing keyboard, a side view of a key (1) of an existing keyboard combined with a circuit board (PCB), and a bottom stereogram of a key (2) of an existing keyboard, and a side view of a key (2) of an existing keyboard combined with a circuit board (PCB). Since the bottom 10 structure of the existing key 1 is provided with a raised portion 11, when it is combined with the circuit board (PCB) 2, there is a gap between the key 1 and the circuit board (PCB) 2. Therefore, when the key 1 of the keyboard is struck or pressed, the gap formed therebetween provides an air medium for transmitting noise. In addition, the raised portion 11 of the existing product causes a knocking sound between the circuit board (PCB) 2, which will make the user feel annoyed for a long time. In addition, the key 1 of the existing product is intended to be connected to the circuit board (PCB) 2 through the material The material structure is changed, usually the cost increases, and it is necessary to ensure that it can perfectly match the circuit board (PCB) 2, and whether the overall combination can be completed in time, which causes it to be inconsistent with the commonly used standard specifications. This causes users to need time to adapt to the new keys, which seriously affects work efficiency. Therefore, the keyboard key 1 is subject to various restrictions. So far, no one has invented a method to reduce the noise generated when tapping or pressing the keyboard key 1 by changing the bottom of the keyboard key 1 and combining it with a noise reduction material structure. There is a raised part 1 under the original key 1, so even if a layer of cushion is added, the noise reduction effect is still poor, which will make the gap smaller during use and reduce flexibility, making it greatly reduced in practicality. This is what technicians in the field and consumers are eager to break through. Summary of the invention
