Embodiment 1

[0030] Such as figure 1 As shown, the sound amplifying device of the present invention includes a sound amplifying device main body 1 and a high-decibel speaker 2 , and the high-decibel loudspeaker 2 is fixed to the sound amplifying device main body 1 through a mounting clip 3 .

[0031] Such as figure 2 As shown, the main circuit board of the sound amplification device 1 includes a voice intercom module, a power amplifier module, and a control module. The signal layer of the circuit board is covered with copper on a large area, and both sides and the bottom layer of the audio signal line and the radio frequency signal are grounded. At the same time, the circuit board follows the principles of separating digital signals from analog signals, and separating radio frequency signals from low-frequency signals, effectively reducing electromagnetic interference and anti-interference performance. The thickness of the circuit board is 0.9-1.3mm, preferably 1.0mm. Since the thicker...

Abstract

The invention provides a wireless air loudspeaking and communication device for a miniature unmanned aerial vehicle, and belongs to the field of wireless loudspeaking. The loudspeaking device provided by the invention comprises a loudspeaking device host and a high-decibel horn, the high-decibel horn is fixed to the loudspeaking device host through a mounting clip, the loudspeaking device host comprises a channel display screen, a frequency alignment turn button and a power line, and the channel is adjusted by adjusting the frequency alignment turn button to keep communication with an interphone. According to the loudspeaking device provided by the invention, performance parameters of a circuit board are calculated, and element placement and circuit wiring are reasonably designed to solve the problem that an analog signal output by a voice intercom module is vulnerable to electromagnetic interference, resulting in signal distortion.

Description

technical field [0001] The invention belongs to the field of wireless sound amplification, and in particular relates to a wireless aerial sound amplification and communication device that can be used for micro-miniature unmanned aerial vehicles. Background technique [0002] In recent years, the UAV industry has developed rapidly. UAVs are not restricted by take-off and landing sites, can take off and land vertically, hover in the air, and can fly flexibly in any direction. Based on the above advantages, drones are now used in many fields, and have shown a booming trend at home and abroad, such as agriculture, detection, meteorology, disaster forecasting and rescue, etc., such as film and television shooting, search and rescue, fire command Wait. [0003] In the process of urbanization, the population gathers and the traffic in the city is congested. It is often necessary to evacuate the crowd and direct the traffic. In addition, the number of high-rise and super high-rise ...
