Abstract
The invention relates to the technical field of interphones, in particular to a DMR digital/analog dual-mode frequency point interphone. The interphone comprises an interphone casing and a protective sheath, wherein the outer wall of the interphone casing is sleeved by the protective sheath; a transmitting antenna is arranged at the upper part of the interphone casing; a switch mounting groove is formed on the outer wall of the interphone casing; a switch mounting seat is arranged in the inner chamber of the switch mounting groove; a change-over switch is mounted on the switch mounting seat; a protective cover is arranged on the right side of the switch mounting groove; a rotating shaft is fixedly connected to the upper end of the protective cover, and is rotationally connected with the protective sheath; a wedge block is integrally formed at the lower end of the protective cover; a limit block is arranged on the protective sheath and corresponding to the wedge block. The DMR digital/analog dual-mode frequency point interphone has the advantages that the mode change-over switch on the interphone can be protected, so that voice information receipt failure due to a wrong mode caused by a mistaken touch on the switch is avoided, and higher convenience and reliability in use are achieved.
