GENDER CHANGER DEVICE IN WHICH POWER-FREE NOISE CANCELLER IS EMBEDDED

WIPO Patent Application WO/2020/256158

A1

One embodiment of the present invention relates to a gender changer device in which a power-free noise canceller is embedded, comprising: a main body (100) including a female connector (102) coupled to a radio-side male connector (300), a barrel (104) coupled to the female connector (102), and a male connector (106) of which one side is coupled to the barrel (104) and of which the other side is coupled to a handset-side female connector (400); and a noise canceller (200) mounted in the main body (100) so as to be electrically connected to the radio-side male connector (300) and the handset-side female connector (400), thereby cancelling noise. According to the present invention, a gender changer in which a noise canceller is embedded is serially connected, as an adapter type, to a conventional handset so as to cancel surrounding noise with a simple connection and without a structure change and damage of the handset, thereby transmitting only clear voice signal information, and a noise canceller that can operate even without a battery or a separate power supply is formed as a gender changer type so as to cancel only mixed noise in a power-free state, thereby transmitting/receiving clear and distinct voice information.
