Abstract
The present disclosure relates to a piano-action. The piano-action may comprises a first moving component including a concavity structure, a second moving component including a convexity structure, wherein the convexity structure and the concavity structure are configured to match each other and capable of being clipped together, and a third moving component being thin and flexible and configured to fixedly fit between the first moving component and the second moving component when the convexity structure of the second moving component is clipped into the concavity structure of the first moving component.
Claims9
A piano-action, comprising:
- a moving device, the moving device including one or more moving components, wherein at least one of the moving components includes an elastic portion, wherein the one or more moving components include:
- a first moving component having a convexity structure;
- and
- a second moving component having a concavity structure,
- wherein the first moving component includes the elastic portion, the convexity structure of the first moving component is configured to extrude into the concavity structure of the second moving component through elastic deformation of the elastic portion, and a second end of the first moving component is configured to move, relatively to the second moving component, through deformation of the elastic portion.
A piano-action, comprising:
- a first moving component including a convexity structure;
- a second moving component including a concavity structure;
- and
- a connecting component configured to rotatably connect the first moving component to the second moving component by assembling the convexity structure into the concavity structure,
- wherein the connecting component has elasticity, the convexity structure and the concavity structure have different radians and are configured to match each other, and the convexity structure is assembled into the concavity structure through a resilience force imposed by an elasticity deformation of the connecting component.
