Son device of interphone

Abstract

A talkback door bell handset apparatus is provided which can arrange a talkback door bell handset in an outer box to unitize the handset and can mount the handset in an outer shell used for presenting the appearance of the handset apparatus. The invention prevents the rainwater from intruding the unitized handset in the outer shell not in the handset so as to realize simplification of the structure and assembly and the simple whole apparatus. The apparatus is provided with a talkback door bell handset arranged in an outer box made of synthetic resin, a long rectangle outer shell made of synthetic resin with opening backside, and circumferential walls around the left and right and the upper side and the lower side formed by extending from the periphery of a front panel to the backside. A receiving part enclosed by the circumferential walls is formed at the lower part of the backside of the front panel, and the outer shell will not project from the circumferential walls to the backside at the status of being carried and clamped by a lower supporting part. A water drop removing eave, which is in hill type and projecting from the front panel to the backside, covers the talkback door bell handset received in the receiving part from the upside. Water discharge grooves are formed among the left end and the right end of the eave and the left side and the right side of the circumferential walls. A water discharge part formed by cutting a break on the circumferential walls is formed on the bottom side of the circumferential wall corresponding to the lower support part.

Description

technical field [0001] The present invention relates to an intercom doorbell device accommodating the intercom doorbell device, in particular to an intercom doorbell device suitable for multi-family houses, the intercom doorbell device has an electromechanical The connected sound element and camera are housed in a synthetic resin case. Background technique [0002] As an intercom doorbell machine with a camera, there has been an intercom doorbell machine with the following structure: the circuit board 5 is screwed on the part corresponding to the mounting plate in the housing 8, and the monitor camera 2 is installed on the circuit board 5 , and make the claws on the upper end of the surrounding wall of the housing 8 engage with the mounting plate 18 of the porch etc. [0003] In addition, there is also an intercom doorbell device that protects the circuit board from contact with rainwater or dew in the device through the sound hole of the outer cover (refer to Patent Docume...

AI Technical Summary

Problems solved by technology

In addition, since the circuit board 2 and the rainwater intrusion prevention plate 5 are accommodated between the body 1 and the outer cover 4, the number of assembly components is large, and the assembly becomes complicated.
