Zusammenfassung:The present invention is directed to a sound reproduction device which includes an LCD (20), which is an exemplary front panel, a case (22), and an electromechanical acoustic transducer (23). TheLCD (20) isoperabletoperformapredeterminedoperation in response to an electrical signal applied thereto. A space (24) for sound emission is formed between the case (22) and the LCD (20). The electromechanical acoustic transducer (23) is connected to the case (22), and emits sound to the space (24). If the electromechanical acoustic transducer (23) emits the sound to the space (24), energy of the emitted sound causes the LCD (20) to vibrate and thereby to externally output the sound.
