Beschreibung
Zusammenfassung:	An infrared emitter comprises a preamplifier, an infrared RF emitter, an infrared channel controller and a photodiode emitting-medium. With the emitter, by switching between two channels with an infrared channel controller, and by the mode of arrangement of a plurality of infrared emitting diodes and two Darlington amplifying circuits on the parts in a photodiode emitting-medium, crosstalk disturbance during transmitting carrier waves to a wireless earphone is inhibited. The emitter is applied to industries of audio/video playing, car audio/video equipment and hi-fi equipment.
