On-off controls, pedals

Abstract

The invention discloses a switching-type control device and pedal, and the device is used for modifying the sound condition of an electronic musical instrument. The device comprises an upper board and a bottom board, wherein the upper board can move up and down relative to the bottom board. The device also comprises a connecting arm which is disposed at one end of the upper board, and comprises a projection which extends towards the bottom board; and an electromagnetic induction power generation module which is located between the upper board and the bottom board, and comprises an electromagnet and an electromagnetic induction coil. The electromagnet or the electromagnetic induction coil is suitable to be driven by the projection to enable the electromagnetic induction coil to make relative movement in the magnetic field of the electromagnet, so as to generate an induced electromotive force. Through the pressing and loosening mechanical energy of the upper board and the self-generation power of the electromagnetic induction power generation module, the device directly supplies power to a wireless circuit module, thereby reducing the supply requirements of a switching-type control device battery and other power supplies, reducing the weight of the switching-type control device, enabling the switching-type control device to be lighter, and enabling the device to save energy and be environment-friendly.

Description

technical field [0001] The invention relates to an electronic musical instrument controller, in particular to a switch type control device and a pedal. Background technique [0002] Pedals are necessary control devices for various electronic instruments such as digital pianos, electronic organs, electric pianos, and electronic drums. They generally include switch-type control devices for changing the sound conditions of electronic instruments. [0003] The traditional pedal signal pickup method is: install a switch button on the pedal, when the pedal is pressed, the switch button is pressed, the power is turned on, corresponding to the level change of the pedal connection, and the pedal signal is sent back to the main controller through the pedal connection , to realize the pedal corresponding function. [0004] Pedals rely on wires to transmit signals. For example, when an electronic piano is placed on the table for performance, traditional pedals need to connect the wires...

AI Technical Summary

Problems solved by technology

[0006] The problem of the prior art is: pedals must rely on batteries or other power sources, which increases the weight of the pedals, makes the pedals not light enough, and is not energy-saving and environmentally friendly. It is also extremely inconvenient to use and carry
