Abstract: The feature of the present invention is to provide a photograph frame having a sound source output function, comprising: a case (110) having thereinside a space unit (111) for receiving a photograph (10) in which at least one person's image (I1) is included; a touch panel (120) which is disposed inside the case (110), wherein the photograph (10) is secured on the upper part of the case in a stacked manner, the touch panel comprising a plurality of touch cells (121) which sense a user's touch operation being input through the upper surface of the photograph (10) and generate a touch signal; a memory unit (130) in which sound source output source data including sound source output touch region (R1) information which is configured to be matched with the form of the person's image (I1) within the entire touch region of the touch panel (120) and sound source setting information of sound source data which is matched with each of the sound source touch regions (R1), and the sound source data are stored; a control ci

Abstract: A film-type audio-speaker is provided that uses a piezoelectric film as a vibration element to provide a reinforcement of the low to medium frequency band sound waves generated. The film-type audio-speaker uses a piezoelectric film as a vibration element and comprises a piezoelectric film with an electrically conductive polymer or metal layer coated on its surface, a terminal portion electrically connected to the piezoelectric film; and an audio-speaker driving unit connected to the terminal portion. The film-type audio-speaker has a cover member that is made of a porous material attached to the front surface and/or the rear surface of the piezoelectric film.

Abstract: The invention is a contact structure of a film-type audio-speaker of a structure appropriate for transmitting audio signal current to the entire audio-speaker surface without attenuating the strength of the signals while achieving enhanced durability. There is provided a contact structure for use in a film-type audio-speaker including a piezoelectric film unit having a piezoelectric film which is obtained by surface-treating a film and coating an electrically conductive polymer layer on the surface of the film, and one or more terminal portions which are electrically connected to a piezoelectric film unit, the contact structure of the film-type audio-speaker comprising: a metal electrically conductive layer coated around the circumference of the piezoelectric film unit, and having a relatively excellent electrical conductivity in comparison with the electrically conductive polymer layer, wherein the terminal portions are in close contact with the metal electrically conductive layer.
