Abstract

The invention provides an intelligent device and a control method. The intelligent device comprises a first sound collection unit, at least one second sound collection unit and a control device, wherein the second sound collection unit is provided with a working state and a non-working state, when at least one second sound collection unit stays at the non-working state, the first sound collection unit stays at the working state; and the control device is used for controlling at least one part in the at least one second sound collection unit to stay at the working state under the situation that a sound signal meets a predetermined condition. The control method comprises the steps of collecting the sound signal through the first sound collection unit when the at least one second sound collection unit stays at the non-working state; and controlling at least one part in the second sound collection unit to stay at the working state under the situation that the sound signal meets the predetermined condition.

Description

technical field [0001] The present invention relates to the control of smart devices, and in particular to an smart device and a control method thereof. Background technique [0002] Currently, a smart device includes a central control device, a sound source localization device independent of the central control device, and a dedicated microphone array composed of four microphones connected to the sound source localization device, such as Figure 7 shown. [0003] Normally, the sound signal is directly transmitted to the dedicated microphone array, and the sound source localization device then processes the sound signal received by the dedicated microphone array, and uses the sound signal received by the dedicated microphone array to perform sound source localization. On the other hand, the sound source localization device also transmits the sound signal received from the dedicated microphone array to the central control device, and the central control device processes the r...
