Essay about loudspeaker 500

What is a loudspeaker used for? You must be saying: "A loudspeaker? Isn't it just used for amplification? What else is it used for?" Don't worry, please listen to me slowly -

Teacher Wang, the head teacher of our class, is the backbone teacher of the school. Because I often worry about things in our class and often attend public classes, my voice is a little hoarse. Teacher Wang bought a loudspeaker and put it next to his jacket pocket during class. Teacher Wang was afraid that someone would call during class and affect the class, so he changed the call ring to vibrate. Who knows, this tune also created a little joke.

One day during class, a person called Teacher Wang. It's funny, when the phone vibrates, the loudspeaker also vibrates and makes a "beep-beep-" sound. At first, Teacher Wang and we were confused: Huh? What is this? After we thought about it for a while, ah! It turned out to be a loudspeaker! I saw Teacher Wang taking out his mobile phone in an orderly manner and looking at it. His expression was really dumbfounding. "Hahahaha!" The class laughed into a mess. When Teacher Wang saw that the discipline in the class was extremely poor, he hung up his phone angrily. Teacher Wang shouted loudly: "What's so funny! That's an important call, but I can't answer it!" Zhang Dezhen, the "live treasure" of our class, asked again: "Teacher Wang! What about the loudspeaker?" Teacher Wang just wanted to criticize Zhang Dezhen, "beep-beep-", the phone rang again. "Hahahahaha!" The whole class laughed wildly again.

After reading the above, you know, right? A loudspeaker is just an electrical appliance!
