In a preferred embodiment, the light-sensitive element is any of photo resistance, photodiode and phototriode
It is a kind of.Photo resistance is made using semi-conducting material, and its resistance can diminish in the presence of light, therefore can be used for visible ray
Carry out light sensing or light measurement, at the same photo resistance reaction speed is fast, small volume, sensitivity high, good reliability and into
This is relatively low, is highly suitable for being used in buzzer control system of the present utility model.Photodiode and phototriode are also
Conventional light-sensitive element, can become electric signal by optical signal, when there is no light irradiation, reverse current very little, and therefore flow through buzzing
The electric current of device is also smaller, reduces the volume of buzzer；When there is illumination, the intensity of light is bigger, and the photoelectric current of generation is bigger, therefore
The electric current increase of buzzer is flowed through, the volume of buzzer is improved.
In another preferred embodiment, also including control device and first electric current in parallel with the light-sensitive element 3
Branch road, the control device is used for according to user instruction, using the second electric current where the first current branch or light-sensitive element
Branch road connects the buzzer.By setting first current branch in parallel with the light-sensitive element 3, can be according to user's needs
Be turned on or off control function of the present utility model, such as when the volume of buzzer need not be controlled using light-sensitive element,
Can be connected with buzzer using the first current branch, when needing light-sensitive element to control the volume of buzzer, can be using the
Two current branch are connected with buzzer, and control mode is more flexible.Specific embodiment passes through embodiment 2 and embodiment 3 simultaneously
It is described with reference to the drawings.
As shown in Fig. 2 a kind of connection diagram of buzzer control system that the utility model embodiment 2 is provided, including
The second current branch 4 where power supply 1, buzzer 2, light-sensitive element 3, light-sensitive element 3, first electric current in parallel with light-sensitive element
Branch road 5, the control device includes that controller (not shown) and the hilted broadsword being arranged between power supply 1 and light-sensitive element 3 are double
Throw switch 6, the single-pole double-throw switch (SPDT) 6 includes that binding post A, binding post B and binding post C, the binding post A connect power supply 1, institute
One end that binding post B connects second current branch 4 is stated, binding post C connects one end of first current branch 5；It is described
Controller is used to be instructed according to user's control, and control binding post A is connected with binding post B, or control binding post A and binding post C
Connection.In the particular embodiment, when user needs to use light-sensitive element to control the volume of buzzer, control single-pole double throw is opened
The binding post A of pass is connected with binding post B, and now electric current flows through power supply, light-sensitive element and buzzer, is detected according to light-sensitive element
Light intensity control buzzer sound size；When user need not use light-sensitive element, control single-pole double-throw switch (SPDT)
Binding post A is connected with binding post C, and now electric current flows only through power supply and buzzer, is not passed through light-sensitive element, thus buzzer sound
Sound size keeps constant.
As shown in figure 3, a kind of connection diagram of buzzer control system that the utility model embodiment 3 is provided, including
The second current branch 4 where power supply 1, buzzer 2, light-sensitive element 3, light-sensitive element, first electric current in parallel with light-sensitive element
Branch road 5, the control device includes controller (not shown), the second controlling switch 7 and the first controlling switch 8, described the
Two controlling switches 7 are arranged in second current branch 4, and are connected with the light-sensitive element 3, first controlling switch 8
It is arranged in first current branch 5；The controller is used to control the logical of the first controlling switch 8 and the second controlling switch 7
It is disconnected.In the particular embodiment, when user needs to use light-sensitive element to control the volume of buzzer, the second current branch is controlled
Conducting, the first current branch disconnects, and now electric current flows through power supply, light-sensitive element and buzzer, is detected according to light-sensitive element
Light intensity controls the sound size of buzzer；When user need not use light-sensitive element, the second current branch of control disconnects,
First current branch conductive, now electric current flow only through power supply and buzzer, be not passed through light-sensitive element, therefore the sound of buzzer is big
It is small to keep constant.
Above in association with Fig. 1~Fig. 3, the structure of the buzzer control system of the utility model embodiment is described in detail.This
Utility model also provides a kind of household electrical appliance, as shown in figure 4, being the structural representation of household electrical appliance, the household electrical appliance include
Above-described buzzer control system.In the particular embodiment, the household electrical appliance can be air-conditioning, humidifier, air
Clarifier and other electrical equipment of buzzer is installed.
The utility model has been connected a light-sensitive element in the control circuit of buzzer, and light-sensitive element is arranged on outside household electrical appliances
The position towards indoor light source of shell, therefore the light intensity of indoor light source can be detected, when light illustrates that more by force interior is opened
Lamp, user has not been entered into sleep state, now the reduction of light-sensitive element resistance, is raised by the electric current of buzzer, buzzer
Loudness is improved, and user will not be interfered；And work as the weaker explanation interior of indoor light and closed lamp or only opened sleeping lamp,
User is likely to be at sleep state, and now light-sensitive element does not receive light or the light that receives is weaker, light-sensitive element resistance
Value is raised, and by the current reduction of buzzer, the reduction of buzzer loudness, therefore does not interfere with the sleep state of user, is improved
User's usage comfort and the satisfaction to household electrical appliances.
