1. A sound-output device, comprising:
a vibration speaker configured to generate a bone-conducted sound wave;
an air-conducted speaker coupled to the vibration speaker through a mechanical structure and configured to generate an air-conducted sound wave; and
a signal processing module configured to generate a control signal, including:
a microphone configured to collect an ambient noise signal,
a bone-conducted signal processing circuit configured to generate a bone-conducted control signal, and
an air-conducted signal processing circuit configured to generate an air-conducted control signal;
wherein the bone-conducted signal processing circuit includes a full frequency signal processing module configured to generate a bone-conducted output signal based on an initial sound wave signal, the full frequency signal processing module includes a phase processor,
the vibration speaker includes a vibration assembly electrically connected to the signal processing module to receive the control signal, and generate the bone-conducted sound wave based on the control signal, and
the air-conducted speaker includes a housing coupled to the vibration assembly to generate the air-conducted sound wave under an actuation of the vibration assembly.
