Volume control method for air conditioner sound production device

Abstract

The invention relates to a volume control method for an air conditioner sound production device, and belongs to the field of air conditioners. The volume control method comprises the following steps: 1, detecting the illumination value of the environment where an indoor unit is located; 2, comparing the illumination value with a preset illumination value to obtain a comparison result; and 3, controlling the output volume of the sound production device according to the comparison result. In other words, when the ambient light is bright, the output volume is large, but when the ambient light is dark, the output volume is small. The volume control method can be implemented independently or implemented in cooperation with adjustment of the brightness of a display screen. In other words, when the ambient light is bright, the output volume is large, and the brightness of the display screen is high, but when the ambient light is dark, the output volume is small, and the brightness of the display screen becomes low or zero. The volume control method has the advantages that full-automatic operation is achieved, user operation is not needed, implementation is simple and convenient, the light detection precision is high, the implementation difficulty is low, and the cost is low.

Description

technical field [0001] The invention relates to a volume control method of an air conditioner sounding device, belonging to the field of air conditioners. Background technique [0002] Traditional air conditioners are equipped with buzzers, which are used as reminders for receiving remote control signals or other alarms; with the development of intelligent air conditioners, some air conditioners have added speakers for music or voice playback. [0003] But at night, when some users are adjusting the air conditioner, there may be someone nearby who is resting or sleeping. At this time, the air conditioner emits a buzzer, music, or voice broadcast, which will affect the rest of others. [0004] The sounding devices of existing air conditioners in the industry generally do not consider volume adjustment, and a small number of smart air conditioners are equipped with mobile phone APPs to adjust the volume of the sounding device. In addition, the application document of patent p...

AI Technical Summary

Problems solved by technology

[0006] 1) The application limitations are large, the air conditioner must have intelligent functions such as WIFI, and ordinary air conditioners cannot be used;

[0007] 2) The operation is relatively troublesome, and the elderly may not use it

[0009] 1) It is impossible to distinguish the noise source, that is, it is impossible to distinguish whether it is the environmental noise brought by external TVs, cars, etc., or the noise generated by the air conditioner itself, such as wind noise and various motor running sounds, transformer electromagnetic sound, refrigerant flow sound, etc., so its The detection of background noise will be interfered by the operating noise of the air conditioner itself, which is technically difficult to implement, high in cost, and unsatisfactory in effect

[0010] 2) Due to the complexity and diversity of the background noise detection algorithm, the method of controlling the volume by detecting the background noise is prone to false triggers, that is, it makes a sound when it should not sound, and outputs a low volume when it should be loud, etc.
