摘要:
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. The LCD 20 is operable to perform a predetermined operation 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.
