[0051] Please refer to figure 1 , is a three-dimensional exploded view of the button for reducing resonance noise of the present invention. This embodiment provides a key that can reduce resonance noise, figure 1 Take a long multiple key as an example, such as a blank key, or a Shift key, or an Enter key, etc. The button includes a substrate 10, a conductive film layer 20 placed on the substrate 10, an elastic conducting member 30 placed on the conductive film layer 20, a connecting rod 40 above the substrate 10, and a The keycap 50 above the connecting rod 40 .

[0052] The substrate 10 has a first support portion 11 and a second support portion 12 . The connecting rod 40 has a body 44 , a first arm portion 41 connected to one end of the body 44 , and a second arm portion 42 connected to the other end of the body 44 . The first arm portion 41 is pivotally mounted on the first support portion 11 , and the second arm portion 42 is pivotally mounted on the second support por...

[0060] The difference between this embodiment and the above-mentioned embodiments is that the plurality of openings 101, 102, 103, 104 of the button are formed on the substrate 10, along the lower position of the connecting rod 40 and adjacent to the first supporting portion 11 and and the second supporting part 12. In this embodiment, except that the holes 101, 102, 103 correspond to the two ends of the body 44 of the connecting rod 40 and are adjacent to the positions of the first arm portion 41 and the second arm portion 42; The plurality of openings 104 are located below the body 44 of the connecting rod 40 and adjacent to the middle of the body 44 , so that the plurality of openings 104 further reduce the resonance effect of the clacking sound generated when the keycap 50 is pressed in the keycap 50 . This embodiment can further reduce the slapping sound generated when the middle part of the keycap 50 is pressed down.

[0061] Furthermore, the conductive film layer 20 of...

Abstract

A key with reduced resonant noise includes a base plate formed with a first supporting portion and a second supporting portion, a conductive film layer, an elastic conducting element, a linking rod, and a keycap on the linking rod. The linking rod has a main portion, a first arm extended from one end of the main portion and pivotally connected to the first supporting portion, and a second arm extended from the other end of the main portion and pivotally connected to the second supporting portion. The key cap has a bottom surface pivotally connected to the main portion of the linking rod. The base plate has openings under the linking rod and adjacent to the first supporting portion and the second supporting portion. The openings are adjacent respectively to the two ends of the main portion and adjacent to the first arm and the second arm, thereby reducing resonant effect of clapping sound in the keycap, when the keycap is pressed.

Description

technical field [0001] The present invention relates to a button and a keyboard that reduce resonance noise, in particular to a button that can reduce the noise generated during operation. Background technique [0002] The development of the manufacturing technology of the keyboard has been towards the reduction of the height, so all the components of the key are getting closer and closer, however, it is required to maintain a sufficient pressing stroke. Therefore, in terms of structural design, the distance originally used to reduce noise is sacrificed. At present, keycaps often directly hit the conductive film and the underlying substrate. [0003] According to the current notebook computer keyboard, the measured noise value is about 60db at a distance of 26 cm above the keyboard. Based on the standard of human factors engineering, this noise value will cause enough noise to interfere with nearby operators. [0004] To explore the source of the sharpest sound when the key...
