扩音器 / Loud-speaker


The design is derived from classic gramophone which is simple in modeling, small in size and easy to carry. The sound will be enlarged over and over again in the spindly microphone through the miniwatt built-in speaker with the features of propagation of sound waves, which reduces power loss and enables your mobile devices work longer and energy conservation and environmental protection.
