Inductive percussion instrument based on wood grain style printing and conductive ink

Abstract

The invention provides an inductive percussion instrument based on wood grain style printing and color conductive ink. The inductive percussion instrument comprises a percussion panel. Conductive color ink blocks are coated on the upper surface of the percussion panel. Sound generating speakers powered by a power supply module are arranged on the lower surface of the percussion panel. The sound generating speakers are connected with the conductive color ink blocks on the upper surface of the percussion panel through conductive color ink lines. According to the inductive percussion instrument based on wood grain style printing and the color conductive ink, vibration and sound generation of the conventional percussion instrument depend on physical percussion, the multipart mode of the capacitive touch percussion instrument is eliminated, and on / off of the sound generating device is realized by using the capacitive induced conductivity of the color conductive ink so that the manufacturing technology is simple, parts are less and the percussion instrument is safe and stable and suitable for children in comparison with the conventional capacitive touch percussion instrument.

Description

Technical field [0001] The invention relates to an induction percussion instrument based on wood grain printing and conductive ink, and belongs to the technical field of children's toys and conductive ink. Background technique [0002] One type of sensor used in games, toys, and books is a capacitive touch sensor. Capacitive touch sensors are typically small capacitors enclosed in electrical insulators. This capacitor has the ability to store charge, which is called capacitance. When the power supply applies an increased voltage across the capacitor, the charge flows into the capacitor until the capacitor is charged to the increased voltage. Likewise, when the power supply applies a reduced voltage to the capacitor, the charge flows out of the capacitor until the capacitor is discharged to the reduced voltage. The amount of time it takes for the capacitor to charge or discharge depends on the change in the applied voltage and the capacitance of the capacitor. If the capacitan...

Problems solved by technology

[0003] This type of capacitive touch percussion instrument often requires a multi-layer structure, including at least a substrate, a capacitive touch sensor protected by glass wrapped on the substrate, exposed wires, a sounding device, and a power module. On the one hand, the process is complex and the production cost Large, on the other hand due to the large number of parts, children have a high probability of damage when playing
