Smartphone et Ultrason?


Recommended Posts


À toutes et à toutes, j'ai une question concernant nos smartphones (ancien ou nouveau). 

Est-ce que nos smartphones de nos jours peuvent emettre / recevoir des ultrasons? 

D'après mes recherches sur google, il me semble que non, mais je voudrais avoir votre confirmation. 

Merci et bonne soirée.
