Problems solved by technology
Due to cost issues, most smartphones currently on the market do not have an integrated LED status indicator function. When there are missed calls or unread text messages, they can only be displayed on the screen of the mobile phone. You need to turn on the screen of the mobile phone to see can not be known to users in time
Although some machines can provide status prompts through the built-in LED flash, due to the serious fragmentation of smartphones, the control interface of the built-in LED flash is not uniform, resulting in poor controllability of the LED flash; plus the rear LED flash is used as an indicator light relatively poor practicality

Abstract
The invention discloses an external LED light emitting device based on audio signal control. The external LED light emitting device comprises a power supply module, a switch control module, an LED lamp and an audio plug; an output end of the audio plug is separately connected with an input end of the switch control module and the input end of the power supply module; and the audio plug is connected with a mobile phone through an audio socket of the mobile phone. The external LED light emitting device disclosed by the invention does not need to be provided with special decoding chip or power supply battery, but is controlled and powered by the audio interface of the mobile phone. The external LED light emitting device can be compatible with two occasion applications, firstly, the external LED light emitting device can be used as a state indicator lamp of the mobile phone, comprising missed call reminding, unread short message reminding and charging state reminding of the mobile phone; and secondly, the external LED light emitting device can be used as a data sending end device to modulate to-be-sent data in the mobile phone in an audio signal, and send the data in a lamp extinguishment mode by driving the LED lamp; and the external LED light emitting device is widely used in the field of mobile phones.
Description
technical field [0001] The invention relates to the field of mobile phones, in particular to an external LED lighting device controlled based on audio signals. Background technique [0002] There is a huge amount of mobile phone usage today, especially smartphones. Smartphones have powerful functions, and various software can be used to enrich the functions of mobile phones. Due to cost issues, most smartphones currently on the market do not have an integrated LED status indicator function. When there are missed calls or unread text messages, they can only be displayed on the screen of the mobile phone. You need to turn on the screen of the mobile phone to see , and cannot be known to users in a timely manner. Although some machines can provide status prompts through the built-in LED flash, due to the serious fragmentation of smartphones, the control interface of the built-in LED flash is not uniform, resulting in poor controllability of the LED flash; plus the rear LED fl...
