Generally, the general population, the light emitting module 6 and the audio module 14 respond at the same time, and emit visible light and audio to realize calls; When sleeping with infants, the mute key 23 is pressed, and the doorbell only emits visible light when calling outside the door, and flashes with conspicuous lights to realize an effective call.

During specific implementation, the circuit board assembly 2 is powered by connecting the external power supply through the plug 5; the control module sends an execution command to the audio module 14 and the light emitting module 6; Corresponding audio chime and visible light. Complete a call by seeing a visible light with your eyes; complete a call with your ears hearing an audio ring; and respond to a call by seeing both a visible light and an audio ring. Among them, people with good hearing can call through sound, and people with poor hearing can call through visible light. After the light source is output to the light-emitting area 4, in order to avoid eye discomfort caused by direct light hitting the eyes, this product uses the light to irradiate the wall or the carrier for visible light reflection, mapping and refraction, etc., to soften and spread the direct visible light , to achieve rear projection effect, high security.

In summary, the present invention arranges the light-emitting area 4 on the back of the housing 1, and the visible light emitted by the light-emitting module 6 of the circuit board assembly 2 is transmitted to the light-emitting area 4, and the visible light passing through the light-emitting area 4 Diffusion is carried out to achieve the effect of calling; the shell 1 has the effect of protecting the internal components, and at the same time can prevent the visible light of the light-emitting module 6 from being exposed from other positions; the external power supply is connected to the circuit board assembly 2 through the plug 5. Drive; since the pin 5 is arranged on the back of the housing 1, when the pin 5 is fixedly connected to the wall, the visible light emitted from the light-emitting area 4 is reflected by the wall to achieve the effect of rear projection, avoiding the discomfort caused by direct visible light to the eyes , high security. Connect the external power supply through the plug 5 to supply power for the circuit board assembly 2; the control module sends execution instructions to the audio module 14 and the light emitting module 6; according to the audio module 14 and the light emitting module 6 receive the execution instructions and send out corresponding audio bells and visible light. Complete a call by seeing a visible light with your eyes; or complete a call with your ears hearing an audio ring; and respond to a call by seeing both a visible light and an audio ring. Among them, people with good hearing can call through sound, and people with poor hearing can call through visible light, which has a wide range of applications and high safety.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the protection of the present invention. within range.
