Embodiment Construction

[0032] Outdoor audio equipment may be located on vehicles (such as cars, taxis), elevators and other mobile carriers, and may also be located in conspicuous positions in commercial areas, residential areas, or some important intersections. In these places, background noise can vary greatly from time to time and from situation to situation. In the existing technology, the set volume is used for playback, and the volume is adjusted or reset by maintenance personnel on a regular basis. The volume cannot be adjusted in real time according to the background situation, so that the sound content cannot be heard clearly in the noisy environment. And when the environment becomes quiet, the sound played becomes noise itself.

[0033] The first embodiment of the present invention includes a background noise monitoring module and a volume control module. The background noise monitoring module detects the background noise in real time and records the value of the background noise. Accordi...

Abstract

The invention discloses a system for adjusting the volume of an outdoor sound device which can adapt to environmental background noise and a device thereof. By using a background noise monitoring module, the background noise can be monitored at real-time; and when the background noise exceeds a preset threshold value and the time length of the background noise achieves a definite value, a volume control module automatically adjusts the volume of the sound device, thereby overcoming the defect that the traditional outdoor sound device can not adjust the volume at real-time. Therefore, the outdoor sound device can adapt to complicated noise environment, meet sound control standards set under different environment, and perform the communication function of the outdoor sound device.

Description

technical field [0001] The invention relates to the technical field of outdoor audio equipment, in particular to a volume adjustment system and method for outdoor audio equipment. Background technique [0002] With the improvement of people's living standards and the improvement of the influence of outdoor audio equipment on people, various audio equipment appear around us, including outdoor mobile TV, audio advertising machines, fixed broadcasting equipment and so on. These devices may be located on mobile carriers such as public transportation (such as cars, taxis), elevators, etc., or may be located in prominent positions in some commercial areas, residential areas, or some important intersections. [0003] In the prior art, the volume of the above-mentioned audio devices is basically set according to experience during installation, and the volume is adjusted or reset by maintenance personnel on a regular basis. The volume cannot be adjusted in real time according to the ...
