Description

Counter intercom with telescopic microphone

Technical Field

The utility model relates to the technical field of counter conversation, in particular to a counter interphone with a telescopic microphone.

Background

When the banking counter handles financial business, because the counter uses the bulletproof glass, the sound insulation performance can lead to small communication sound between staff and clients on two sides of the counter and can not effectively communicate, so that interphones can be used for improving communication effects.

For example, chinese patent CN218006455U discloses a novel interphone, in which the existing interphone is generally directly placed on a desk of a worker, and a gooseneck is generally used to connect a microphone with a base. Although the microphone can be fixed in any space direction to the gooseneck, the length of the gooseneck is not suitable to be set too long, otherwise, the gooseneck cannot be effectively fixed, and the gooseneck is not telescopically prolonged, so that the movable distance of the microphone is greatly limited, when a call is conducted, a worker is required to pick up an interphone or body tilts forwards to be close to the microphone of the interphone, the use of the worker is inconvenient, and the cost of the gooseneck is high.

The other scheme is that the microphone is connected with the counter interphone of the interphone main body through the wire harness, and the staff can directly pick up the microphone without being limited by the length, but the problem that the plastic shell of the wire harness is easy to wear and age and the wire harness is too long to wind on a tabletop and is on an object or knotted is also existed.
