That is, the annular microphone array can identify the type of the user according to the acquired sound information, and when the types of the users are multiple and have priority levels, the air supply mode of the fan can be determined according to the priority levels.
For example, the priority of children may be set higher than that of the elderly people, the priority of the elderly people may be set higher than that of the adults people, and when the types of the users including children and adults are detected at the same time, it is determined that the fan blows air according to the type of the children.
It should be understood that the type of the user may be obtained from the energy of the sound collected by the ring-type microphone array, for example, when the energy of the sound collected by the ring-type microphone array is larger, it is determined that the corresponding user is better in physique and may be a man or an adult, and when the energy of the sound collected by the ring-type microphone array is smaller, it is determined that the corresponding user is weaker in physique and may be a woman or an old man. Therefore, the type of the user can be determined by collecting the voice energy of the user from the annular microphone to the array, the air supply type can be adjusted according to the type of the user, and further, the air supply type can be directly adjusted according to the energy.
The blowing type may include a blowing air volume and a blowing speed, for example, when the user is an adult or a man, the blowing air volume may be larger, the blowing speed may be higher, and when the user is a woman or an old, the blowing air volume may be smaller, and the blowing air speed may be lower. Wherein the air supply speed may comprise a yaw speed.
In summary, according to the control method of the fan in the embodiment of the present invention, the sound collection device array collects the sound information of the user, and determines the horizontal included angle and the vertical included angle between the user and the center line of the fan according to the collected sound information, so as to adjust the pitch angle and the panning angle of the fan according to the horizontal included angle and the vertical included angle.
