Problems solved by technology

The above-mentioned answering machines are mainly used for voice prompts in small areas. Since their purpose is mainly for leaving messages, the appealing answering machines all adopt the method of recording and playing, which is extremely inconvenient when the content needs to be replaced, so the above-mentioned devices cannot be used for playing radio advertising field
Moreover, the above-mentioned equipment is mainly implemented by integrated circuits, and its functions and storable content are greatly restricted, and its functions cannot be further expanded, and its humanized control cannot be performed.

Abstract

The invention relates to audio player trigged by wireless induction. The structure includes CPU, memory, inductor for sensing existence or movement of human body such as infrared inductor, audio decoding circuit, loudspeaker and power. CPU is connected to memory, inductor, decoding circuit; audio playing back circuit is connected to loudspeaker. Power provides electricity for relevant devices.

Description

technical field [0001] The invention relates to the field of audio playback equipment installed in public places or indoors, and more specifically relates to a wireless induction audio player that activates audio playback through wireless induction. technical background [0002] The existing advertising players or music players installed in public places mainly adopt three modes of continuous playback, timing playback and artificially controlled playback or a mixed mode of these three modes. [0003] The continuous playback mode is generally suitable for places with relatively dense traffic. It will be played continuously when the traffic is large. When the traffic is small, the playback will be turned off in order to save resources. However, since the traffic of people changes all the time, this method can only be used It is based on the daily traffic statistics, such as playing during the day and not playing at night, so the place where the continuous broadcasting method i...
