AI Technical Summary

Problems solved by technology

Due to the relatively limited installation position of the pedal, the rotation angle is also limited. When the transmission part of the pedal pushes the rod of the sensor, the maximum rotation angle of the potentiometer (that is, the sensor) cannot be realized, and the sound effect range is narrow.

Abstract

The invention discloses a pedal device of an electronic keyboard instrument. The pedal device comprises a pedal body and a potentiometer, wherein a rod part for driving the potentiometer to rotate isarranged on the potentiometer; an extending part extending towards the front end side of the pedal body is arranged on the rod body; a transmitting part is arranged at the position, corresponding to the extending part, of the bottom of the pedal body, wherein the upper surface of the extending part abuts against the lower surface of the transmitting part, the upper surface of the extending part isa cambered surface and always keeps in contact with the bottom surface line of the transmitting part in the relative moving process. The pedal device has the advantages that the extending part is arranged on the rod part of the potentiometer so as to obtain greater rotation angle of the potentiometer by using smaller rotation angle of the pedal, so that a larger range of sound effect is obtained.

Description

technical field [0001] The invention relates to the technical field of musical instruments, in particular to a pedal device of an electronic keyboard musical instrument. Background technique [0002] In recent years, electronic keyboard instruments such as electronic pianos that simulate the timbre, operability, appearance, etc. of an acoustic piano have been widely used. As the pedal device used in this electronic keyboard instrument, disclosed in the Chinese patent disclosed on September 21, 2011: the pedal device of electronic keyboard instrument, application number: 201110050844.3, the sensor is to detect the pedals of each pedal, The member that outputs the resistance value corresponding to the amount of depression, has a rod that rotates with the depression operation of each pedal, and outputs the rotation amount corresponding to the rod, that is, the depression amount of each pedal. A variable resistor (not shown) of resistance value is constructed. In addition, the...
