description The utility model discloses a novel interphone. The interphone comprises an interphone aluminum shell, a mainboard, a battery, an antenna interface, a first antenna used for receiving and transmittingfrequency modulation mode radio frequency, a channel switching button, a mode switching button and a second antenna used for receiving and transmitting public network mode radio frequency, the channel switching button and the mode switching button are both electrically connected with the mainboard, a support is arranged in the interphone aluminum shell, an installation groove is formed in one side edge of the support, and the second antenna is arranged on the installation groove and connected with the mainboard through a cable. According to the utility model, switching between the first antenna and the second antenna is realized through the mode switching button, and a frequency modulation and public network dual-mode interphone is realized; by arranging the built-in second antenna, the hardware structure of the
