Document Type and Number:
WIPO Patent Application WO/2020/168687
Kind Code:
A1
Abstract:
Provided in the present application is a dual protruding mesa sound-producing key structure, comprising a substrate, a flexible component, a button, a cap, and an engaging spring. A first recessed cavity used for accommodating the button is provided on the base. A hollow first guide column is provided at the center at the bottom of the first recessed cavity. A second guide column is provided at the bottom of the button; the second guide column movably runs through a cavity of the first guide column. The flexible component is sleeved on the exterior of the first guide column and is abutted respectively on either end to the lower end of the first guide column and to the top end of the second guide column. The engaging spring is a symmetric structure and comprises two acting parts and a connecting part connecting the two acting parts. The engaging spring is arranged within a second recessed cavity on one side of the first recessed cavity. The button is provided on the side thereof above the engaging spring with a protruding block fitting the acting parts. The acting parts comprise protruding mesas. The protruding mesas are connected at one end to the connecting part and are outwardly extended on the other end to form protruding dots. The distance between the two protruding dots provided opposite each other is less than the maximum width of the protruding block. The present application is for use in providing a structurally simple and dustproof sound-producing key structure.
