Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The working principle of the scheme is briefly described as follows:

when the sound box works, the temperature sensor detects the temperature inside the sound box and sends the temperature to the first wireless communication module connected with the control system through the third wireless communication module, after the control module receives relevant temperature data, the preset temperature data is extracted from the storage module and compared, when the real-time temperature exceeds a set critical value, the control module controls the fan driver to start the fan inside the sound box to cool the inside of the sound box, the damage to internal components and devices caused by overhigh temperature is avoided, the illumination intensity of the outside is detected by the illumination sensor and sent to the control module through the second wireless module, when the real-time temperature is lower than the critical value, the system judges that the sound box is in the evening, when the sound box is started but is not controlled by people, the system automatically selects a small playing volume to store a first player with a comparatively mild music type to play music, and when the illumination intensity exceeds the critical value, control module will select the volume great, the comparatively fast second player of storage music, through this kind of mode, the system is when unmanned control audio amplifier, the broadcast volume, the more suitable music of kind, audio amplifier is D class amplifier, efficient low distortion has, frequency response curve is good, peripheral components and parts advantage few, under the normal broadcast condition, a size for can adjust the volume in the button module on the audio amplifier, accessible bluetooth pairs the external other broadcast sources of button simultaneously, the accessible charges the interface and charges for the audio amplifier, when charging successfully simultaneously, the charge pilot lamp can light.

Furthermore, the key module comprises a volume adjusting key, a Bluetooth pairing key and a power key, the volume can be adjusted, and meanwhile, the Bluetooth pairing key is externally connected with other playing sources.

Furthermore, the first player is a player with low volume and relatively gentle music storage; the second player is a player with large volume and fast music storage, and by the mode, the system plays music with more appropriate volume and type according to time intervals when the loudspeaker box is not controlled by a person.

Further, the temperature sensor adopts a non-contact temperature sensor, and the upper limit of measurement is not limited by the temperature resistance degree of the temperature sensing element, so that the maximum measurable temperature is not limited in principle. For high temperature above 1800 ℃, a non-contact temperature measurement method is mainly adopted. With the development of infrared technology, radiation temperature measurement is gradually expanded from visible light to infrared, and the radiation temperature measurement is adopted from below 700 ℃ to normal temperature and has the advantage of high resolution.
