Walkie talkie long in transmission distance

Abstract

The invention discloses a walkie talkie long in transmission distance. The walkie talkie comprises a walkie talkie body, an AVR processor, a recording chip and a radio frequency transceiver, wherein the radio frequency transceiver is mounted in the walkie talkie body and electrically connected with the AVR processor, the output end of the AVR processor is electrically connected with the input end of an audio power amplifier, the output end of the audio power amplifier is electrically connected with the input end of a loudspeaker, the input end of the AVR processor is electrically connected with an input keyboard, the output end of the AVR processor is electrically connected with the input end of a liquid crystal display screen, the output end of the AVR processor is electrically connected with the input end of an MIC audio circuit, the output end of the MIC audio circuit is electrically connected with the input end of the recording chip, and the output end of the recording chip is electrically connected with the input end of storage. The walkie talkie has the advantages that by the radio frequency transceiver comprising a radio frequency transceiving chip, a frequency modulation and demodulation chip and a radio frequency power amplifier chip, the walkie talkie is good in expansibility and long in transmission distance.

Description

technical field [0001] The invention relates to the technical field of walkie-talkies, in particular to a walkie-talkie with a long transmission distance. Background technique [0002] The walkie-talkie is a two-way mobile communication tool, which plays an important role in both production and life. However, the existing walkie-talkies have many defects, such as short transmission distance, and the inability to connect to earphones, which is prone to eavesdropping. , the safety is poor, and the walkie-talkie cannot locate the user. In an emergency, it cannot arrive at the scene in time, often breaks, and has a short service life. Contents of the invention [0003] The purpose of the present invention is to provide a walkie-talkie with a long transmission distance to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a walkie-talkie with a ...
