Wireless ultra-long distance audio broadcasting device capable of performing secondary modulation and amplification

Abstract

The invention discloses a wireless ultra-long distance audio broadcasting device capable of performing secondary modulation and amplification. The device comprises a bottom plate, bases are fixedly connected to the two sides of the bottom of the bottom plate; a balancing weight is arranged between the two bases; the top of the bottom plate is fixedly connected with a shell; a first-stage amplification chip is mounted at the bottom of an inner cavity of the shell; a second-stage amplification chip is mounted above the first-stage amplification chip; circuit boards are installed on the inner walls of the two sides of the shell; the circuit board penetrates through the side wall of the shell and extends out of the shell; the circuit boards are electrically connected with an antenna, signal transmission lines are electrically connected between the first-stage amplification chip and the two circuit boards, a plurality of wires are electrically connected between the first-stage amplificationchip and the second-stage amplification chip, the top of the shell is fixedly connected with a sound amplification cover, and a broadcasting mechanism is arranged in the sound amplification cover.

Description

Technical field [0001] The invention relates to the technical field of broadcasting equipment, in particular to a wireless ultra-long-distance audio broadcasting equipment capable of secondary modulation and amplification. Background technique [0002] A wireless audio transmitter is an audio transmitter that can wirelessly transmit audio signals in real time. It can achieve long-distance wireless audio transmission functions, and is usually used in broadcast equipment. However, due to the structural design of the existing audio broadcasting equipment, its amplification effect on audio signals is limited, which makes the sound propagation distance unable to meet higher demands. Therefore, there is an urgent need to improve the existing wireless audio broadcasting equipment. Summary of the invention [0003] The technical problem solved by the present invention is to overcome the shortcomings of wireless audio broadcasting in the prior art with short propagation distance and low so...
