Electronic percussion instrument with knocked area detection function

Abstract

The invention provides an electronic percussion instrument with a knocked area detection function. The electronic percussion instrument comprises an elastomer, a membrane switch, and a knocked position detecting circuit. The membrane switch comprises a first elastic insulated layer, a second elastic insulated layer, an insulation isolation structure, conductive films, and an insulated isolation belt. The first elastic insulated layer is pasted right under the elastomer. The second elastic insulated layer is arranged right under the first elastic insulated layer. The insulation isolation structure is arranged between the first elastic insulated layer and the second elastic insulated layer. The conductive films are arranged on the surface of the first elastic insulated layer and the surface of the second elastic insulated layer. The insulated isolation belt divides one conductive film into multiple conductive areas. The knocked position detecting circuit is electrically connected with the membrane switch. The conductive film is divided into the multiple conductive areas and the insulation isolation structure is arranged between the conductive films. Thus, knocking signals in the knocked areas can be accurately detected. Different music is provided by detecting different positions. Thus, good hearing feeling can be provided for a bandsman.

Description

technical field [0001] The invention relates to the field of electronic percussion instruments, in particular to an electronic percussion instrument with a percussion area detection function. Background technique [0002] In the prior art, electronic percussion instruments that can detect percussion areas such as figure 1 , which has: a drumhead 14 (elastic beating surface), an upper layer of conductive film 15, a middle grid-shaped insulating isolation layer 13, a bottom layer of conductive film 17 and an insulating support substrate 16. The underlying conductive film is divided into a plurality of concentric conductive regions 17a, 17b and 17c. When the drumhead 14 is struck, the deformation of the drumhead 14 makes the upper and lower conductive films contact each other, thereby forming a conduction loop. [0003] However, in the above-mentioned electronic percussion instrument, the grid-like insulating spacer 13 is as figure 2 It is shown as a grid, and the grid-like...
