Abstract
The utility model discloses a self-adaption volume regulating and controlling device of an advertisement terminal. The self-adaption volume regulating and controlling device of the advertisement terminal is characterized in that the self-adaption volume regulating and controlling device of the advertisement terminal comprises a control module, the control module comprises an analog to digital (A/D) converter, a micro processing chip and a volume regulating module, an output end of the A/D converter is connected with an input end of the micro processing chip, an output end of the micro processing chip is connected with an input end of the volume regulating module, an input end of the A/D converter is further connected with a sound sensor, and an output end of the volume regulating module is connected with an audio output module which is arranged inside the advertisement terminal. The sound sensor is arranged outside the advertisement terminal. The self-adaption volume regulating and controlling device of the advertisement terminal is simple in principle, surrounding noise volume is detected through the sound sensor, processed by the A/D converter and transmitted to the micro processing chip, the surrounding noise volume is analyzed by the micro processing chip, and the volume of the advertisement terminal can be automatically regulated according to the surrounding noise volume to meet different environment requirements.
Description
Technical field
The utility model relates to a kind of self adaptation volume control device of advertisement terminal.
Background technology
Along with the development and progress of society, bus, subway, square, hotel and many public arenas all are provided with the advertisement terminal, and continual broadcast advertisement and news information circulate.But fixing often at the sound of the advertisement terminal plays of these public arenas, relatively quietly the time, can seem very noisy; And when environment is more noisy around, seem that again sound is too little, do not hear at all.
The utility model content
The purpose of this utility model provides a kind of self adaptation volume control device of advertisement terminal.
To achieve these goals, by the following technical solutions, a kind of self adaptation volume control device of advertisement terminal, it is characterized in that: the self adaptation volume control device of described advertisement terminal comprises control module, this control module comprises A/D converter, little process chip and volume adjusting module, wherein, the output of A/D converter connects the input of little process chip, and the output of little process chip connects the input of volume adjusting module; The input of described A/D converter also is connected with sound transducer, and the output of volume adjusting module links to each other with the audio frequency output module of advertisement terminal inner.
In order effectively to survey the noise content in the advertisement terminal surrounding environment, described sound transducer is arranged at the advertisement terminal outside.
The utility model principle is simple, survey noise content on every side by sound transducer, after A/D converter is handled, pass to little process chip then, analyzed by it, and according to the automatic sound size of regulating the advertisement terminal of the size of noise content, to be adapted to different environmental demands.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the scheme of installation of the utility model embodiment.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described further.
Extremely shown in Figure 2 as Fig. 1, a kind of self adaptation volume control device of advertisement terminal, comprise control module 1, this control module 1 comprises A/D converter 1-1, little process chip 1-2 and volume adjusting module 1-3, wherein, the output of A/D converter 1-1 connects the input of little process chip 1-2, and the output of little process chip 1-2 connects the input of volume adjusting module 1-3; The input of described A/D converter 1-1 also is connected with sound transducer 2, and the output of volume adjusting module 1-3 links to each other with the audio frequency output module 3 of advertisement terminal 4 inside.
In order effectively to survey the noise content in the advertisement terminal surrounding environment, described sound transducer 2 is arranged at advertisement terminal 4 outsides.
In the use, noise content around sound transducer is surveyed, then the noise content that detects after handling, A/D converter is passed to little process chip, little process chip is analyzed it, and make judgement according to the size of noise content, determine the volume that current advertisement terminal should be exported, then the control signal of correspondence is exported to volume adjusting module, audio frequency output module by volume adjusting module control advertisement terminal inner, realize regulating automatically the function of advertisement terminal sound size, to be adapted to different environmental demands.
The utility model not only can be used for also can be used for making it possess the self-adapting volume control function on the multiple electronic products such as domestic TV, mobile phone, sound equipment on the advertisement terminal of public arena.
