Sound hammer device for electronic keyboard instrument

Abstract

The invention discloses a sound hammer device for an electronic keyboard instrument. The sound hammer device comprises a connecting rod, and two telescopic rods are arranged on each of the two sides of the connecting rod in a front-back symmetrical mode; the outer side faces of the telescopic rods are connected with damping springs in sleeved mode, second mounting plates are arranged on the lowerend faces of the telescopic rods, and a supporting plate is arranged in the middle of the outer side face of the connecting rod; supporting columns are arranged at the upper end of the outer side faceof the connecting rod and rotationally connected with levers through hinges arranged on the upper surfaces of the supporting columns; and second magnetic sheets are arranged on the right side of theupper surface of the supporting plate. According to the sound hammer device for the electronic keyboard instrument, the structure is simple, operation is convenient, the occupied space is small duringusing, the sensitivity of a sound production part of the electronic keyboard instrument can be effectively improved, when the sound hammer device is collided, the damping springs can achieve a good damping effect, through arrangement of balancing weights, knocking hammers quickly rebound advantageously, and through combined arrangement of the second mounting plates and a first mounting plate, thesound hammer device can be mounted and fixed very conveniently.

Description

technical field [0001] The invention relates to the technical field of musical instrument hammers, in particular to a hammer device for electronic keyboard musical instruments. Background technique [0002] A hammer device is disclosed in Japanese Laid-Open Patent Publication (Kokai) No. 2010-262129. Such a hammer device is applied to a keyboard device of an electronic piano. The hammer device includes an action chassis formed by metal extrusion, and a plurality of hammers pivotally supported by the action chassis and arranged side by side in a left-right direction. The action chassis includes a hammer support portion having a fulcrum portion extending in the left-right direction and is provided on an upper portion of the hammer support portion in such a manner as to extend obliquely forward and upward from the hammer support portion. in the switch installation section. A key switch for detecting key depression information on the associated key is mounted to the switch mo...

AI Technical Summary

Problems solved by technology

The hammer device used for electronic keyboard instruments has an excessively large stroke between the percussion part and the sounding part, resulting in insufficient sensitivity of the sounding response of the hammer device, and the hammer device is bulky and cannot meet the needs of small electronic keyboard instruments.
