Description

Technical Field

[0001] This utility model relates to the field of walkie-talkie technology, specifically a full-duplex voice walkie-talkie. Background Technology

[0002] A voice intercom, also known as a two-way radio voice intercom, is a portable two-way communication device that uses radio signals for point-to-point or point-to-multipoint communication. It requires no network support, incurs no call charges, and is suitable for situations requiring frequent calls. It is an intercom device that can simultaneously send and receive data. A full-duplex voice intercom means that during voice communication, both parties can speak and hear each other's speech at the same time. Full-duplex communication relies on two independent transmission channels: one for sending data (voice) and the other for receiving data (voice). The intercom uses a full-duplexer or similar signal processing technology to separate and manage the transmitted and received signals, ensuring that both parties can communicate simultaneously.

[0003] When using walkie-talkies, users often hold them directly in their hands. However, during prolonged use or when running, the walkie-talkie can easily slip from the user's hand, causing it to collide with the ground and become damaged, affecting its normal use and performance. To address this, a full-duplex voice walkie-talkie is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a full-duplex voice intercom to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a full-duplex voice intercom, comprising an intercom body, a display screen on the upper part of the front surface of the intercom body, a control keyboard on the lower part of the front surface of the intercom body, a slot on the upper part of the front surface of the intercom body, a strip inserted into the inner wall of the slot, a transparent protective shell fixedly connected to the front surface of the strip, a cover hinged to the lower left side of the front surface of the intercom body, a blind groove on the right side of the rear surface of the cover, magnetic strips fixedly connected to the lower right side of the front surface of the intercom body and the inner wall of the blind groove, and an elastic rope fixedly connected to the middle of the rear surface of the intercom body. One end of the elastic cord is fixedly connected to an elastic ring, and a sleeve post is fixedly connected to the upper rear surface of the walkie-talkie body. A baffle is fixedly connected to the rear surface of the sleeve post. When the walkie-talkie is not in use, the magnetic strips between the cover are magnetically attracted to lock the cover, protecting the control keypad and preventing accidental touches. The display screen can be protected by inserting the insert strip and the transparent protective shell, reducing dust corrosion and preventing scratches on the display screen. When using the walkie-talkie, the elastic ring is removed from the sleeve post and put on the operator's wrist. Even if the walkie-talkie slips from the operator's hand during use, the elastic cord will pull it in place, preventing the walkie-talkie from falling directly to the ground and being damaged.

[0006] As a further preferred embodiment of this technical solution: an antenna is mounted on the left side of the upper surface of the walkie-talkie body; a channel adjustment knob and a volume adjustment knob are mounted on the right side of the upper surface of the walkie-talkie body; an intercom button is mounted on the upper part of the right side wall of the walkie-talkie body; a microphone hole is provided on the right side of the front surface of the walkie-talkie body; a speaker hole is provided on the left side of the front surface of the walkie-talkie body; and a power indicator light is mounted on the side of the front surface of the walkie-talkie body near the speaker hole. The walkie-talkie body has two independent transmission channels, one for transmitting data (voice) and the other for receiving data (voice). The walkie-talkie body uses a duplexer or similar signal processing technology (this is a mature technology in the market and will not be elaborated on here) to separate and manage the transmitted and received signals, ensuring that both parties can communicate simultaneously.

[0007] As a further preferred embodiment of this technical solution: a light is installed on the rear side of the upper surface of the walkie-talkie body; this facilitates increased illumination in the dark.

[0010] As a further preferred embodiment of this technical solution: a knob is fixedly connected to the right end of the pin; this facilitates turning the pin.

[0011] As a further preferred embodiment of this technical solution: a silicone strip is adhered to the right side wall of the cover.

[0012] As a further preferred embodiment of this technical solution: two rubber pads are symmetrically bonded to the lower part of the outer side wall of the walkie-talkie body.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] When the walkie-talkie is not in use, the magnetic strips on the closed cover lock the cover in place, protecting the control keypad and preventing accidental touches. The display screen is protected by inserting the insert strip and transparent protective shell, reducing dust erosion and preventing scratches. When using the walkie-talkie, the elastic ring is removed from the sleeve and placed on the operator's wrist. Even if the walkie-talkie slips from the operator's hand, the elastic cord will hold it in place, preventing it from falling directly to the ground and being damaged. This effectively protects the full-duplex voice walkie-talkie, ensuring its normal use and improving its performance. Attached Figure Description
