Abstract
A keyless control device is provided, wherein the first infrared sensor module generates an infrared trigger signal when the earphone is in a wearing state; the Bluetooth controller generates enable signals according to the infrared trigger signal, and the left-ear infrared sensor module generates a first detection signal according to a first enable signal; the right-ear infrared sensor module generates a second detection signal according to the second enable signal; the left-ear acceleration sensor module generates a third detection signal according to the third enable signal when detecting that the left-ear component is knocked; the right-ear acceleration sensor module generates a fourth detection signal according to the fourth enable signal when detecting that the right-ear component is knocked; and finally, the Bluetooth controller performs the functions according to the detection signals.
