An electronic apparatus connection cable includes: a first plug including a first power reception terminal; a first switch coupled to the first power reception terminal; a power transmission line coupled to the first switch; a second plug coupled to the power transmission line; and a first light emitting element coupled to the power transmission line. The distance between the first light emitting element and the second plug is smaller than a distance between the first emitting device and the first plug. When the first power reception terminal receives a first input voltage and the first switch is conducted, the first light emitting element emits light.

Electronic apparatus connection cable with identification information providing function

An echo-cancelling device includes an audio input/output (I/O) terminal, an audio-receiving module, an analog-to-digital (A/D) converter, and a processor is provided. The A/D converter is electrically connected to the audio-receiving module. The processor is electrically connected to the A/D converter and the audio I/O terminal. The audio I/O terminal receives an external reference signal from an electronic device. The audio-receiving module receives an input audio and an output audio from the electronic device, and generates an analog input signal having the input audio and the output audio. The A/D converter generates a digital input signal according to the analog input signal. The processor cancels the output audio to generate a second (digital) sound signal according to the digital input signal and the external reference signal. Finally, the processor transmits the second (digital) sound signal to the electronic device via the audio I/O terminal.
