Abstract
A smart device for reducing sound leakage includes a frame, a main sound-generating device, an auxiliary sound-generating device, and a controller. The controller is configured to generate a control signal based on an electrical signal of the main sound-generating device to trigger the auxiliary sound-generating device to generate sound, so that the sound generated by the auxiliary sound-generating device and sound generated by the main sound-generating device through the sound outlet hole are superposed on each other, or the sound generated by the auxiliary sound-generating device and sound leakage generated by the main sound-generating device through the sound leakage hole form a dipole effect and counteract each other. The smart device according to the present disclosure can further reduce the sound leakage to improve privacy of the smart device for reducing sound leakage, which can also achieve an effect of improving sound quality.
