Abstract: A structure of a sounding device primarily includes a plurality of holding chambers dug on a floor tile and are kept a distance from an opposite surface of the floor tile. A sounding device and a button circuit are located in the holding chambers, and the sounding device can give off sound upon pressing the button. Upon laying the floor tile, the surface of the aforementioned device is faced down on ground, so as to isolate children or people with a contact surface of the aforementioned device.

Abstract: A method of transfer printing includes first pasting an adhesive of a solvent-type on an object, then covering a transfer film on the object under a condition of half-dry of the adhesive, and next exerting pressure according to a form of the object for uniformly gluing an ink of the transfer film onto the object, and finally tearing off a plastic film on a surface of the transfer film, thereby accomplishing the transfer printing. In addition, a mold release agent is pasted between the plastic film and the ink, and the viscosity of the adhesive is larger than that of the mold release agent, so as to uniformly and firmly attach the ink to the object, and to remove the mold release agent along with the plastic film, during the aforementioned workflow.
