Description

Counter weight keyboard of simulation weight key effect Technical Field The utility model relates to the technical field of musical instruments, in particular to a weight keyboard simulating the effect of a weight key. Background The key weight is a touch design in a keyboard instrument (e.g., an electronic piano, an electronic organ, or a MIDI keyboard) intended to simulate the mechanical touch of a conventional piano. The key principle of the piano is that through a physical structure, the piano key generates resistance and inertia similar to those of a real piano when being pressed down, and the piano key provides playing experience more similar to that of an acoustic piano. The traditional electronic keys are used for simulating the touch feeling of the piano weights, and mechanical weights or lever structures are adopted, so that the problems of complex parts, high cost, hard touch feeling and the like exist. Disclosure of utility model The utility model mainly aims to provide a counterweight keyboard simulating the effect of a heavy hammer key, aiming at improving the touch feeling of the key and reducing the production cost of the key.
