The loudspeaker demonstrates the principle of electroacoustic sound transduction. See the video “Sound emission at the loudspeaker”.
Information and ideas:
The process of electroacoustic sound transduction can be explained very well to the students with the help of a technical device that is familiar to all of them. Furthermore, the production and propagation of sound waves – important in human physiology for hearing and speaking – can be shown.
Relevant for teaching:
Communication and understanding
Vibrations and waves
