A main body is formed by integrally attaching a plurality of panels provided in the form of a rectangular parallelepiped. An insertion groove is formed on at least one of the plurality of panels to insert a smart phone. A plurality of inlet holes are formed integrally on each panel so that sound generated in the speaker of the smart phone passes through. A loudspeaker hole is formed in a stepped manner on both sides or center of the plurality of panels so that the sound passing through the inlet hole can be loud. The present invention is designed to provide a method for manufacturing a powerless speaker capable of performing a speaker function which can make small sound generated in the smart phone loud as well as reducing the amount of power used for increasing the sound of a smart phone so as to minimize battery consumption, wherein the appearance is good and thus the speaker can be utilized as an interior piece. |
