Novel interphone

Abstract

The invention relates to a novel interphone. The top of an interphone body is provided with an antenna; the antenna comprises a connection part and an antenna part; the connection part is connected with the antenna part through a damping revolving shaft; the connection part is in threaded connection with the interphone body; the antenna part comprises a protection sleeve on an outer layer, a protection cover on a middle layer and an antenna core on an inner layer; a buffer spring is arranged between the protection sleeve and the protection core in a sleeving way; the outer surface of the protection sleeve is provided with a plurality of ring slots which are formed side by side; an acquisition circuit, an audio amplifying circuit, a modulated transmission circuit, and a gating circuit which is connected with the acquisition circuit, the audio amplifying circuit and the modulated transmission circuit are arranged inside the interphone body; a back cover comprises a back cover body; an end part of the back cover body is provided with a buckle; an end part of a side wall of the back cover body is provided with an insertion block; an edge of the back cover body is provided with a raised bar; the raised bar is provided with a sliding chute; a card slot is formed in a position which is adjacent to the insertion block; and the end part of the back cover body is also provided with an assembly hole.

Description

technical field [0001] The invention relates to an instant communication product, in particular to a novel walkie-talkie. Background technique [0002] The walkie-talkie is a two-way mobile communication tool, which is mainly used for communication and command and dispatch among group members, so as to improve communication efficiency and improve the rapid response ability to deal with emergencies, especially suitable for the situation where there is no communication network in the wild. In order to increase the communication distance, the existing walkie-talkies generally use an external antenna, which can increase the sensitivity of signal receiving and sending, thereby enhancing the communication effect. [0003] The external antenna is generally installed on the top of the walkie-talkie. Whether it is in use or in storage, the antenna may be accidentally impacted due to misoperation, which is very easy to bend the antenna and cause the connection between the antenna and ...

Problems solved by technology

[0003] The external antenna is generally installed on the top of the walkie-talkie. Whether it is in use or in storage, the antenna may be accidentally impacted due to misoperation, which is very easy to bend the antenna and cause the connection between the antenna and the walkie-talkie to break. damage, or even break the antenna, and ultimately affect the communication of the walkie-talkie

The reason for the above problems is that the structural design of the e
