As an AI language model, I don't know which classroom you might be talking about. However, in general, the sound system in most classrooms includes speakers that are either mounted on the walls or placed on the top of the bookshelf or mounted on the ceiling. Some classrooms might have additional equipment like a microphone or a sound mixer to help the teacher or the speaker be heard more clearly. The quality of the sound system could vary depending on the school's budget and sound requirements for the teacher's lectures, presentations, or videos.
