Title:
ULTRA COMPACT DEVICE AND PROGRAM
Document Type and Number:
Japanese Patent JP2018164247
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To solve a conventional problem in which an ultra-compact device connected to a computer uses a method using radio waves, such that there are few corresponding computers, and manufacturing cost of devices to be connected is high.SOLUTION: A program that requires a code signal based on audio is used for an ultra-compact device that can transmit a code signal from a built-in speaker by audio including audible range audio and inaudible range audio and a computer with built-in microphone that can receive an audio, such that the number of corresponding computers increases. Since no radio waves are used for the connection, the number of parts used is reduced. This not only reduces the manufacturing cost of the device to 1/10 but also allows further miniaturization.SELECTED DRAWING: Figure 3
