| titleOfInvention | Manufacturing method of transparent acoustic speaker using femtosecond laser treatment process |
| abstract | A method of manufacturing a transparent acoustic speaker using a femtosecond laser processing method using a glass and a PVDF-based flexible transparent piezoelectric element is disclosed. In the method of manufacturing a transparent acoustic speaker using the femtosecond laser processing method according to the present invention, (a) forming a first electrode and a second electrode on the upper and lower surfaces of the piezoelectric film, respectively, and then covering the first and second electrodes, respectively. Forming a first and a second insulating film to provide a piezoelectric element; (b) processing the upper and lower glass primarily with a femtosecond laser to form first and second micro cavities, and then secondly processing with a femtosecond laser to connect with the first and second micro cavities, respectively. Forming first and second through holes; (c) forming a second adhesive member on the upper surface of the lower glass, and then attaching the piezoelectric element on the upper surface of the lower glass via the second adhesive member; And (d) forming a first adhesive member on an upper surface of the piezoelectric element, and then attaching the upper glass to the upper surface of the piezoelectric element via the first adhesive member to bond the lower glass to the lower glass. In the step (b), the femtosecond laser is characterized in that for irradiating with a beam size of 10 ~ 30㎛. |
