A sound reproduction device 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.
