1. A sound-output device, comprising:
a vibration speaker configured to generate a bone-conducted sound wave; and
an air-conducted speaker configured to generate an air-conducted sound wave, wherein
the vibration speaker is coupled to the air-conducted speaker through a mechanical structure, wherein
a first mechanical vibration is generated by the vibration speaker to cause the bone-conducted sound wave, a second mechanical vibration is generated under an actuation of the first mechanical vibration, and the second mechanical vibration causes the air-conducted sound wave, such that a vibration derived from the vibration speaker is input to the air-conducted speaker at least in part as an input signal.
