Counter weight device used for electronic piano

Abstract

The invention relates to the technical field of electronic musical instruments, and in particular relates to a counter weight device used for an electronic piano. The counter weight device comprises afixing base, a counter weight part, a first connector for connecting with a key of the electronic piano, and a second connector used for connecting with a piano body of the electronic piano, whereinthe counter weight part is connected with one end of the fixing base, the second connector is rotatably connected with the other end of the fixing base, the first connector is rotatably connected withthe fixing base, and the joint of the first connector and the fixing base is positioned between the counter weight part and the second connector. For the device provided by the invention, the counterweight device capable of being arranged at the end part of the key and having the center of gravity capable of changing along with the different pressing degrees of the user is utilized for replacinga counter weight rod needing to be arranged below the key, so that under the premise that the pressing hand feeling of the key is guaranteed, the length of the key can be arranged to be shorter, andmeanwhile, the effect that the miniaturization of the electronic piano is realized so that the portability of the electronic piano is improved is achieved.

Description

technical field [0001] The invention relates to the technical field of electronic musical instruments, in particular to a counterweight device for an electronic piano. Background technique [0002] In order to make the electronic piano have the feel of a traditional piano, manufacturers of electronic pianos often use counterweight devices to counterweight the keys. The existing electronic piano with full counterweight utilizes the counterweight bars arranged under the keys to carry out the counterweight. One end of the counterweight rod is provided with a counterweight, the other end is connected with the pressed part of the key, and the middle part is hinged with the piano body. The center of gravity of the counterweight rod will change during the rotation process, which can better simulate the feeling of the traditional piano that the resistance will change when playing. In order to make the weight bar have a long enough moment arm so that there is strong resistance when...

AI Technical Summary

Problems solved by technology

When the user presses the keys, the spring will stretch to make the user feel the resistance, but the effect of using the spring to imitate the traditional piano feel is not satisfactory, because the spring cannot provide strong resistance, and the resistance provided by the spring is constant, and the resistance change cannot be simulated feel
