Description

Technical Field

[0001] This utility model relates to the field of fan technology, and in particular to a fan with anti-interference function. Background Technology

[0002] In the application of voice-controlled fans, the vibration of the device itself is a key issue affecting the accuracy of voice recognition. Traditional fan designs are not optimized for the anti-interference requirements of the voice acquisition module. The connection between the fan housing and the support frame is mostly rigid, and the vibration energy is directly transmitted through the metal or plastic parts. The mechanical vibration generated by the fan rotating components (such as motors and fan blades) during operation is transmitted through the fan housing to the support frame, and then to the sound acquisition unit (such as microphone), causing vibration noise to be superimposed on the voice signal, reducing the accuracy of voice recognition.

[0003] Therefore, in order to solve the problem of fan vibration being transmitted to the microphone, a new type of fan with anti-interference function is proposed. Utility Model Content
