摘要： The present invention provides an electronic apparatus including a touch pad. The electronic apparatus also includes a housing and a mechanical acoustic transducer. The housing supports an outer circumferential portion of the touch pad via a suspension to provide a space for sound emission between the housing and the touch pad. The electromechanical acoustic transducer is connected to the housing, and emits sound into the space. When the electromechanical acoustic transducer emits the sound into the space, an energy of the sound emitted causes the touch pad to vibrate and thereby to output sound outside the electronic apparatus.

摘要： 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.

摘要： A sound-driving loudspeaker system is achieved with a simple structure and is capable of easily improving acoustic characteristics. The loudspeaker system emits sound by driving a diaphragm panel by an electromechanical acoustic transducer. The loudspeaker system includes a board, the diaphragm panel whose rim is fixedly attached to the board so as to form a space and which has a stiffness lower than that of the board, and the electromechanical acoustic transducer for emitting sound into the space. With this structure, the diaphragm panel is flexed to be vibrated by the sound emitted from the electromechanical acoustic transducer.
