Assignee: SHENZHEN SHOKZ CO., LTD.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
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,
wherein 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;
the signal processing module includes:
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,

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 air-conducted signal processing circuit includes:
a frequency divider module configured to decompose the initial sound signal into a high frequency signal component and a low frequency signal component,
a high frequency signal processing module coupled to the frequency divider module and configured to generate a high frequency output signal based on the high frequency signal component, and
a low frequency signal processing module coupled to the frequency divider module and configured to generate a low frequency output signal based on the low frequency signal component.
