Interphone capable of increasing reception and sound amplification and effectively preventing dust

Abstract

The invention relates to the technical field of communication signal products, and discloses an interphone capable of increasing reception and amplification and effectively preventing dust. The interphone comprises a body, and a button panel and a display screen are connected to the front surface of the body; a sound outlet hole and a chute are formed in the front surface of the body, and a sliding shell is connected to the surface of the body; a sound amplification hole is formed in the front surface of a sliding block, and a clamping groove is connected to the surface of a fixed seat; a sliding block is connected to the back face of the sliding shell, a sound receiving hole is formed in the back face of the sliding shell, a dustproof film is connected to the back face of the sliding shell, a sound outlet horn is arranged in the machine body, and a dustproof net is connected to the surface of the sound outlet horn. According to the interphone capable of increasing reception and amplification and effectively preventing dust, through the use of the sliding shell and the dustproof film, dust is isolated outside the sound outlet horn, noise can be effectively reduced, through the useof the sound receiving hole and the sound amplification hole, sound emitted by the interphone is amplified, sound emitted by personnel is concentrated, the dialogue effect can be enhanced, and the information is effectively transmitted.

Description

Technical field [0001] The present invention relates to the technical field of communication signals, in particular a walkie-talkie that increases radio and ambiguous and effective dust. Background technique [0002] During the large-scale construction project, the cooperation between various departments and various positions can be used to complete the construction work accurately. In the process of collaboration, it is essential to exchange between staff. Exchange will need to use communication tools. In the construction site, most signals are poor, and there is more noise, and the general mobile phone does not meet the requirements of the accurate call, so there is no need to network, and the conversation is good. [0003] The walkie-talkie is a two-way mobile communication tool. If you do not need any network support, you can call, no phone bills, applicable to relatively fixed and frequent calls, walkie-talkie in architecture, mining, KTV, and security systems The applicatio...
