What is the principle for megaphone?

The sound is introduced into the narrow end of the megaphone, by holding it up to the face and speaking into it, and the sound waves radiate out the wide end. The megaphone increases the volume of sound by increasing the acoustic impedance seen by the vocal cords, matching the impedance of the vocal cords to the air, so that more sound power is radiated. It also serves to direct the sound waves in the direction the horn is pointing. It somewhat distorts the sound of the voice because the frequency response of the megaphone is greater at higher sound frequencies.

What are the main differences between brass and wind instruments in terms of their construction, sound production, and playing techniques?

Brass instruments are made of metal and have a mouthpiece that players buzz their lips into to produce sound. Wind instruments are typically made of wood or metal and have a reed or mouthpiece that players blow air through to produce sound. Brass instruments have a bright and bold sound, while wind instruments have a softer and more mellow sound. Playing techniques for brass instruments involve using the lips and breath control, while wind instruments require precise fingerings and breath control.
