Product use: guides, military police, film shooting, explosion-proof and flood to direct
product features: 1. power big sound far
2. clear voice loud and
use:
combines advanced modeling and using a new type of integrated circuits for the amplifier output, high power sound louder, Bulky, novelty, transmission distance, and so on. Handheld power music propaganda with propaganda and music features, easy to use and reliable, better than similar products. This product is suitable for tourism, group meetings, mini-games, traffic policing, emergency command and other occasions.




1.信号流程：
MIC (microphone) receives the → sound → into weak voltage signals amplified by the small-signal amplifiers → volume potentiometer (you can control
Volume) → PA → Loudspeaker (speaker).    

2. Note:
Require power from the circuit, such as battery, AC power supply, is generally based on the size requirements to determine power supply voltage. 
Regulator (regulator IC, voltage regulator tubes) converts the voltage into a relatively stable and low voltage provided to the MIC, small-signal amplifier
Circuit power amplifier section does not need to be regulated.
Card making is more complicated, if you want to consider self-excited, voice distortion, noise, energy saving and other issues.
