New description: [New technical field] This creation is a kind of sound reduction button structure. The button structure with buffer to reduce noise. Guan Wenwen [Prior Art] People shop, 'has a wide variety of electronic products for people to use, and / various interfaces to communicate with electronic products, such as press / month', touchpad, tablet, etc. With the sensing technology and the development of human technology, the movement of the human eye can also be a kind of control and input mode. However, in daily life, the button is still the most common man-machine cleaning mode. In addition to the computer keyboard, most of the operations of photocopiers, washing machines, microwave ovens, and mobile phones in the office are performed by buttons. Today's computer input method is based on tapping the keyboard with the control mouse or touchpad as the main axis. First, please refer to FIG. 1, which is a schematic diagram of a button structure of the prior art. As shown in Figure 1, an electronic device has a housing 11, a substrate 12, and two button structures 10a, 1b. The button structure i〇a includes a switching element 14a and a button portion 13a. The button structure 10b includes a switching element 14b and a button portion 13b. The electronic device 1 in the figure is a touch panel of a notebook computer. The structure of the button portion is taken as an example, and the substrate 12 is a circuit board. The switching elements 14a and 14b are disposed on the upper surface of the substrate 12. The button portions 5 M341887 13a and 13b are respectively disposed on the button openings 11〇a and u〇b, and are exposed to the casing 11, and the button portions 13a and 13b are respectively provided. The button openings 11a, 11b, and the outer portion are provided in the body 11, and the button portions 13a, 13b have a regenerative force. When the upper surfaces of the button portions 13a, 13b are pressed, the button portions 13a, 13b The lower surface touches the switching elements 14a, 14b, and when the pressing force is applied, the key portions 13a, 13b can be returned to the position by the elastic restoring force. However, when the button structures l〇a, l〇b are actuated, the sound source is always accompanied by a relatively disturbing actuating sound, which is caused by the internal structure of the switching elements 14a, 14b. However, due to the various types of switching elements 14a, 14b, the cause of the noise generated by the internal structure is also different. In the following, only the touch switch is taken as an example to explore the effect of noise noise. Press, today's touch-open relationship is widely used in consumer electronics, such as desktop computers, notebook computers (for touchpad buttons, hotkeys, etc.), computer peripherals (such as display buttons, mouse buttons, etc.) Audio and video equipment, etc. Please refer to Figure 2. This figure is a schematic structural view of a switching element 14. As shown in FIG. 2, a switching element 14 includes a key cap 141, a metal piece 142, and a base 143. The base 143 has a first electrode 151 and two second electrodes 152a and 152b. The metal piece 142 is a The circular cap conductive sheet 'overlies the inner bottom of the base 143, and the key cap 141 is disposed above the metal piece 142. Next, please refer to FIG. 3A and FIG. 3B, which are schematic cross-sectional views of the switching element 14 of FIG. As shown in FIG. 3A, the switching element 14 is not activated, and the first electrode 151 and the second electrode 152a, 152b 6 M341887 are not turned on; as shown in FIG. 3B, the switching element 14 is actuated. In this case, the key cap 141 is actuated downward by an external force. At this time, the lower edge of the key cap 141 applies a force to the top end of the metal piece 142 to deform the metal piece 142, thereby turning on the first electrode 151 and the second electrode 152a, 152b. When the force applied to the upper surface of the keycap 141 is removed, the metal piece 142 is restored to the shape of the original circular top cover by an elastic restoring force, and the key cap 141 is also returned to the position. The actuating noise of the switching element 14 is derived from the deformation process of the metal piece 142, and is attached to the internal space of the electronic device 1 to be a closed space. Referring to FIG. 1, the above-mentioned switching element 14 which generates the actuating noise is located here again. In the space, the speaker effect is formed in this way, and the sound is further amplified. The actuation noise of the above-mentioned switching element 14 is particularly obvious in electronic products such as notebook computers and mouse, because the computer and its peripheral devices are indispensable devices for modern work and leisure, and the input and click actions are usually transmitted through With the push of a button, the user and the people around him often have trouble with this noise. Therefore, how to use materials and various structures to reduce or even eliminate the sound of this consistent button, so that users and surrounding people can not be disturbed by button noise when using electronic devices, and the designers of the real system often think And the subject. [New Content] The main purpose of this creation is to provide a sound-reducing button structure that can effectively reduce the key-acting noise and prevent the user from disturbing the button noise M341887.

The circuit board 420 is provided with a circuit board 42 on which the circuit board 42 is placed. The scissor structure 41 is further placed with a key cap = the switch of the scissors type switch 420, and the film circuit board 42 and the chain are connected. In order to facilitate the opening of an elastic body 44, the elastic body 44 is disposed between the circuit=40 and further disposed on the scissors structure 41. The scissors structure 4 is connected to the other switch 420 and connected through the plate 43. Therefore, the keycap 40 is different from the bottom plate I, the cap 40 and the bottom, which is different from the prior art, and the scissors bell moves up and down. A buffer member 440 is provided in the middle, and in the fourth embodiment, the 哕41 and the bottom plate 43 of the body 44 (Rubber Dome) are formed, and the 440 system is integrally formed with the elastic body 44.忒 忒 Η 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 剖面 剖面 剖面 剖面 剖面 剖面 剖面 : : : : : : : : : : : : : : : : : : : : : The buffer member 44〇 is first contacted, so that the lowering force of the keycap 4〇 is first absorbed by the buffer member 440, so that the click sound when the keycap 40 is tapped can be reduced. Fig. 6 is a cross-sectional view of the structure of the reduced-key button of the present invention, which shows an example of the cross-section, which is omitted for convenience, and the scissors structure, the elastic body and the circuit board are omitted.
