Embodiment

[0030] An embodiment of the present invention provides a voice-controlled smart fan, see figure 1 , the voice-controlled smart fan includes:

[0031] Motor 1 is used to drive the voice-controlled intelligent fan to rotate. In practical applications, the noise of the smart fan mainly comes from the operation of the motor 1 and the rotation of the blades of the smart fan. Since the rotation of the motor 1 is not always at the same frequency, the noise of the smart fan is mainly nonlinear noise. voice commands can cause strong interference.

[0032] The first microphone 2 is set facing the smart fan, and is used to obtain the noise signal emitted by the smart fan when it is working. In practical applications, the first microphone 2 can be a unidirectional microphone, and it is set facing the noise source, and is mainly used to collect noise signals from the smart fan, especially nonlinear noise.

[0033] The second microphone 3, which may be an omnidirectional microphone, is s...

Abstract

A voice-controlled smart fan, comprising: a motor (1) driving a fan to rotate, a first microphone (2), a second microphone (3), a noise cancellation module (4), a voice storage module (5), a voice recognition module (6), and a processor (7). The first microphone (2) obtains noise signals sent by the smart fan, and the second microphone (3) obtains voice instruction signals sent by a user; and then, according to a nonlinear noise cancellation algorithm pre-stored in the noise cancellation module (4) and the noise signals obtained by the first microphone (2), noise signals needing to be filtered out are simulated, and the voice instruction signals obtained by the second microphone (3) are filtered; finally, the voice recognition module (6) recognizes the voice instruction signals in which the noise signals are filtered out, to obtain corresponding voice instruction information, and the processor (7) controls the smart fan to execute the voice instructions. The voice-controlled smart fan is simple to use and provides good user experience.

Description

technical field [0001] The invention relates to the technical field of smart home appliances, in particular to a voice-controlled smart fan. Background technique [0002] In recent years, with the rapid development of the Internet and the Internet of Things technology, smart home appliances relying on these two technologies have also developed rapidly, and have begun to be widely used in people's daily life, greatly enriching people's daily life. [0003] In the rapidly developing field of smart home appliances, voice control of home appliances is popular due to its convenience in operation. However, in household appliances, the fan generates a lot of noise during its operation, which seriously interferes with the recognition of the user's voice, which makes it difficult to prepare a voice-controlled smart fan. Contents of the invention [0004] In order to solve the problem that a fan generates a lot of noise and interferes with voice recognition, making it difficult to ...
