Sound on a brass instrument comes from a vibrating column of air inside the instrument. The player makes this column of air vibrate by buzzing the lips while blowing air through a cup or funnel shaped mouthpiece. To produce higher or lower pitches, the player adjusts the opening between his/her lips.
What is the principle of electric horns?
Electronic horns are used on vehicles to give out warning signals generated by an electronic circuit. A solenoid is magnetized and demagnetized to produce the fundamental frequency and cause the diaphragm to vibrate. This generates high pressure that passes through the trumpet horn to generate a sound.
