Description

Technical Field

[0001] This utility model relates to the field of sensing and detection equipment, specifically a piano key force sensing structure. Background Technology

[0002] Piano keys, pronounced as "keys," are the black and white keys on organs and pianos used to adjust the pitch. A piano has 88 keys: 52 white keys and 36 black keys. Ordinary piano keys are made of ABS plastic through injection molding and then attached to colored wood cut into the shape of piano keys. Modern high-end pianos often use ebony black keys, which are absorbent and have a better feel.

[0003] For example, the piano key force sensing structure described in (Authorization Announcement No. CN218996345U) relates to the field of sensing and detection equipment technology. It solves the problem that after piano key maintenance, adjustments still need to be made based on the user's feel, leading to cumbersome key force maintenance and adjustment due to repeated user trials. The piano key force sensing structure includes an upper frame; a lower frame is provided below the upper frame; a sensing frame slides vertically on the top of the upper frame; upper rollers are arrayed at the bottom of the upper frame; and a force display panel is fixed to the front top of the upper frame.

[0004] The aforementioned device displays the force numerically using a force indicator panel, providing users with an intuitive comparison of the feel of the piano keys before and after repair, reducing the time spent repeatedly adjusting the key force. However, the aforementioned device does not have a mechanism to emit an indicator light after pressing the key, which means that customers cannot intuitively observe the pressure applied to the key after pressing it.
