Handheld Megaphone

Description
The handheld megaphone is also called mini megaphone. Receiving the sound, the MIC changes it into a micro voltage signal by its amplifier. Then after passing the volume potentiometer (controlling the volume), the signal enters into the power amplifier. Finally, the micro voltage signal reaches the loudspeaker. Considering self-excitation, sound distortion factor, and noise energy conservation, this kind of handheld megaphone is more complex.

Application
The handheld megaphone is mainly used for teaching, tourist guiding, and outdoor activities.

Features
1. This megaphone enjoys longer service time, with lithium battery, and it can work for a long period as much as 5 to 6 times than that of other similar products.
2. With the power of 15w, this mini megaphone is better at amplifying sound, and the effect of amplifying sound is 5 to 6 times than that of common loudspeakers.
3. Ordinary loudspeakers adopt common rechargeable batteries that are replaced once a year. But, this handheld loudspeaker is equipped with lithium batteries with a service life of 5 to 6 years.
4. This min megaphone can also broadcast MP3 music and computer music.
5. Compared with handheld mikes, this handheld megaphone has the absolute advantage of freeing users' hands.

Notice: Power is needed for the handheld megaphone's circuit. If batteries or alternating currents are used, the power's voltage can be decided in terms of the power. Regulators (voltage regulator IC, voltage regulator tubes, etc) are used to transform the power voltage into a more stable low voltage for MIC, micro signal amplifiers and other circuits. The power amplifier does not need a voltage regulator.
