Buzzer volume control method and control system

Abstract

The invention belongs to the field of control, and particularly relates to a household appliance buzzer volume control method and control system. The embodiment of the invention provides a buzzer volume control method and control system. Duty ratio information of corresponding PWM square waves is taken according to collected controlling parameters of the buzzer volume under the current working environment of household appliances, and an MCU controller outputs PWM square waves with fixed-frequency according to the duty ratio information to adjust the volume of a buzzer. Various forms of controlling parameters of the buzzer volume are provided, but the volume of the buzzer is mainly adjusted through changing the duty ratio of the PWM square waves, outputting fixed-frequency PWM square waves is conducted to keep the tone of the buzzer unchanged, and it is only need to adjust the volume to adapt to different usage scenarios. The buzzer volume control method and control system have the advantages of being high in portability, simple, convenient and fast, and easy to achieve.

Description

technical field [0001] The invention belongs to the control field, and in particular relates to a control method and a control system for the volume of a household appliance buzzer. Background technique [0002] At present, the buzzer of most home appliances has a single notification volume. When the home appliance with this type of buzzer needs to be controlled in a quiet environment, the sound of the buzzer will become noise; and when the home appliance with this type of buzzer is controlled in a noisy environment, the buzzer The sound of the buzzer is not loud enough, so the single notification volume of the existing buzzer is difficult to meet the different experiences and needs of users in different application scenarios. Contents of the invention [0003] In view of this, the object of the present invention is to provide a control method and control system for the volume of the buzzer of household appliances, so as to solve the problem that the single notification v...
