When you are listening to a song with other people, you have to increase the speaker volume or you could just put it into this paper cup. The paper cup acts like the loudspeaker. This speaker is highly portable. If you are working outside, it can be folded and is easy to carry. The speaker’s lightweight and compact produce good sound quality. Two products, the loudspeaker and the rubber lens hood, have been combined in this design. This small-sized speaker packs a lot of power.
