PURPOSE: A transparent electromagnet film and a thin film speaker device using the same are provided to use vertical vibration by inputting a frequency of a transparent electromagnet cell, thereby generating a sound on an LCD screen without a separate speaker device. CONSTITUTION: A first transparent electromagnet coil film(100a-3) is formed on one side of each vibration point. The first transparent electromagnet coil film comprises a first transparent electromagnet coil(100a-1) and a first transparent conductive electrode(100a-2). A second transparent electromagnet coil film is formed in the lower part of the first transparent electromagnet coil film. The second transparent electromagnet coil film comprises a second transparent electromagnet coil and a second conductive electrode. A transparent electromagnet film(100) includes the first transparent electromagnet coil film and an interlayer connection electrode. A lower transparent electromagnet film(102) is formed in the lower part of an upper transparent electromagnet film. |
