EXAMPLE III

Referring to fig. 12, fig. 12 is a flowchart of a calling method of a doorbell according to the present invention. The invention also provides a calling method of the doorbell, which comprises the following steps:

and S101, connecting an external power supply through the plug pins 5 to supply power to the circuit board assembly 2.

The doorbell is only an electronic device, and has no power supply, so that an external power supply needs to be connected to supply power to the doorbell, and the internal electronic element is driven by the power supply to work. Because the main electronic component in the doorbell is all installed on circuit board 13, comes the power supply to electronic component through circuit board 13, has reduced the arrangement of wire for the doorbell is smaller and more exquisite, simple to operate.

Furthermore, an external power supply is connected through a lead to supply power to the circuit board assembly 2, and the safety is not high because the external power supply is directly connected to the circuit board assembly 2 through the lead.

Further, the circuit board assembly 2 is powered by a built-in power supply. The power supply is safe, but the built-in power supply occupies a certain space, so that the doorbell is crowded inside and inconvenient to assemble.

S102, the control module sends an execution instruction to the circuit board assembly 2; the circuit board assembly 2 comprises a circuit board 13, an audio module 14 with wires arranged on the circuit board 13 and a light emitting module 6.

The audio module 14 and the light module 6 only emit sound and visible light, and cannot control the sound and the visible light by themselves. The control module gives an execution instruction to the audio module 14 and the light emitting module 6, and the audio module 14 and the light emitting module 6 are controlled by the execution instruction.

Further, the execution instruction includes a single light call, a single sound call, and a common sound and light call.

And S103, sending out corresponding audio ring tone and visible light according to the execution instruction received by the audio module 14 and the light-emitting module 6.

Specifically, the invention has two different modes of use scenarios: firstly, in general conditions, the light emitting module 6 and the audio module 14 respond at the same time to emit visible light and audio to realize calling; II, under special conditions: when the old with ears and back, the people with hearing impairment and the infants sleep, the mute key 23 is pressed, and the doorbell only emits visible light when the door is called outside, so that the visible light flickers to realize effective calling.

In specific implementation, the plug pin 5 is connected with an external power supply to supply power to the circuit board assembly 2; the control module sends an execution instruction to the audio module 14 and the light-emitting module 6; and sending out corresponding audio ring tone and visible light according to the execution instruction received by the audio module 14 and the light-emitting module 6. Visible light is seen through eyes to complete the call; or hear an audio ring tone through the ear to complete the call; and simultaneously seeing a visible light and hearing an audio ring tone to collectively respond to the call. The voice call can be made to a person with good hearing, and the visible light call can be made to a person with poor hearing. Because the light is output to the luminous zone 4 through the light source, in order to avoid the light from directly irradiating the eyes to cause discomfort, the product adopts the light irradiation wall body or the bearing object to carry out the transmission forms of visible light reflection, mapping, refraction and the like, and the directly emitted visible light is transmitted in a softening way, thereby realizing the rear projection effect and having high safety.

In summary, the light emitting region 4 is disposed on the back of the housing 1, the light emitting module 6 of the circuit board assembly 2 transmits the emitted visible light to the light emitting region 4, and the light emitting region 4 disperses the transmitted visible light to realize the calling effect; the shell 1 has a protection effect on internal components, and can prevent visible light of the light-emitting module 6 from being exposed from other positions; an external power supply is connected through a bolt 5 to provide driving for the circuit board assembly 2; because the bolt 5 is arranged on the back of the shell 1, when the bolt 5 is fixedly connected to the wall, the visible light emitted from the luminous zone 4 is reflected by the wall to realize the rear projection effect, the discomfort of eyes caused by the direct irradiation of the visible light is avoided, and the safety is high. An external power supply is connected through a bolt 5 to supply power to the circuit board assembly 2; the control module sends an execution instruction to the audio module 14 and the light-emitting module 6; and sending out corresponding audio ring tone and visible light according to the execution instruction received by the audio module 14 and the light-emitting module 6. Visible light is seen through eyes to complete the call; or hear an audio ring tone through the ear to complete the call; and simultaneously seeing a visible light and hearing an audio ring tone to collectively respond to the call. The system can call a person with good hearing through sound, and can call a person with poor hearing through visible light, so that the system is wide in application range and high in safety.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
