In class exercise 9

In this week I need to find some symbols about sound.




I found 3 logos from interenet . I think there are representative. First icon is about a note, it's a musical note. As we know it is a notation representing he pitch and duration of a music sound.






This icon is about a microphone，as the dictionary says, a microphone a device used in sound-reproduction systems for converting sound into electrical energy, usually by means of a ribbon or diaphragm set into motion by the sound waves. The vibrations are converted into the equivalent audio-frequency electric currents Informal name mike. Therefore I think its related to sound.






A loudspeaker is always used for representing a sound symbol because it's a device that converts electric signals to audible sound.









I designed this symbol, the concept is a loudspeaker and the sound waves.
