[0002] The built-in venetian hollow glass is a new type of external sunshade product. By adjusting the closing, lowering or deflection of the venetian blind blades, the required indoor lighting requirements, sunshade effect and privacy protection can be obtained. Most of the existing built-in venetian hollow glasses control the flipping of the blades and the lifting and lowering of the venetian blind through manual magnetic control and electric control.

[0003] The built-in venetian hollow glass driven by electricity realizes the lifting and lowering of the venetian blind as needed and the flipping of the blades as needed by effectively controlling the working state of the motor, such as forward rotation or reverse rotation, the degree of rotation, etc. In this control process, a control mechanism with relatively reasonable structure must be provided. Moreover, with the extensive and in-depth promotion of fully automatic intelligent products in society, the built-in venetian hollow glass driven by electricity is also showing an increasingly intelligent development trend.

[0004] The working principle of the voice control device of the existing hollow venetian glass: The user issues a voice command through an online voice device such as Tmall Genie or Baidu Smart Speaker. The online voice device converts the voice command into a wireless signal and transmits it to the wireless repeater. The wireless repeater transfers the wireless signal to the receiving controller to control the opening and closing and flipping of the venetian blind. The above operations rely on the wireless network and the online voice device, are restricted in use in areas without network, and have relatively high costs.

[0005] Therefore, it is urgent to design an off-line voice control device for an electric hollow venetian glass that can be controlled off-line. Content of the Utility Model
