Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an intercom apparatus.

2. Description of the Related Art As is well known, intercom devices are devices that allow conversation with other places indoors or outdoors, and intercom master units are mostly installed indoors, and there are wall-mounted and stationary types. Are divided into an embedded type and an exposed type, and are roughly classified into a handset type shown in FIG. 4 and a hands-free type shown in FIG. In addition, 9 and 10 are housings, 8 is a handset, and 11 is a call button.

Problems to be Solved by the Invention At present, the intercom system is becoming a part of the interior of the house, and the exposure amount has been reduced, in other words, thinning has become a requirement of the age. It is an issue to measure it.

Means for Solving the Problems In the intercom apparatus of the present invention, therefore, a housing is provided with a hole in which a handset receiver is detachably locked, and a ventilation hole for a speaker is provided at a position facing the handset that is hung on the handset receiver. By forming a ventilation hole for a microphone in the housing, the housing can be shared by both the handset system and the hands-free system.

Action To use the handset type case as a hands-free type case, it can be shared by removing the handset receiver from the case.

Embodiment FIG. 1 and FIG. 2 show an embodiment of the present invention, and FIG. 3 is a view showing a handset receiver 1.

FIG. 1 shows an intercom device with a handset 2.
The handset receiver 1 is a separate piece and the housing 3 has nails 7
Is detachably attached.

FIG. 2 shows a hands-free intercom device using the housing 3 of FIG. 1, and a panel 1a is attached to the mounting portion of the handset receiver 1 from the back side, and a ventilation portion 1b in the housing 3 is provided. A speaker 4 and a microphone 5 are incorporated in the parts 1 and 1c, a hole is further formed in the housing 3, and a call button 6 is newly provided therein. The call button 6 is a switch used for starting and ending a call with another intercom device as well as detecting whether or not the handset 2 is hung up.

FIG. 3 shows a component diagram of the handset receiver 1 of FIG. 1, which has an undercut-provided pawl 7 and is press-fitted into the housing 3 so as to prevent it from coming off and to be fixed.

As described above, according to the present embodiment, the housing can be shared and the intercom device with a handset can be changed to a hands-free intercom device, resulting in a thin and inexpensive intercom device.

As described above, according to the present invention, the handset receiver of the intercom apparatus is configured to be detachable from the housing, and the housing has the ventilation holes for the speaker and the ventilation holes for the microphone. Since the body can be shared by both the handset system and the hands-free system, it is possible to provide an inexpensive intercom device. Further, since the housing is shared, only one molding die needs to be prepared, and the housing molded by the molding die is 1
Since there are different types, there is no need for extra inventory and inventory space for the housing, and storage management costs can be reduced. Further, by positioning the ventilation hole for the speaker and the ventilation hole for the microphone formed in the housing so as to face the handset when using the handset method, even if the housing is used for the handset method, When the handset is hung on the handset receiver, the ventilation hole for the speaker and the ventilation hole for the microphone are hidden by the handset and there is no problem in appearance.
