Problems solved by technology
[0002] In the on-duty business of the police handling the scene, there is only a police light device above the police car, and there is no voice prompt device on the police car. If it is necessary to shout, it is usually shouted by the police with a loudspeaker. Due to the personal reasons of the police, sometimes in Some personal emotions, or accents, or dialects are included in the shouting, which leads to poor shouting effect. In serious cases, it will cause disputes and affect the effect of duty. Therefore, some voices are standardized, and the voice device is installed on the police car as the equipment for the police. Change the existing police equipment, and the color expression of the police lights is not very rich, and needs to be improved

The present invention discloses a LED alarm lamp device with voice. The LED alarm lamp device with voice is provided with a single chip microcomputer; the input end of the single chip microcomputer is connected with a key array (2); one group of output ends of the single chip microcomputer is connected with the display circuit of the LED lamp, and the other group of output ends of the single chip microcomputer is connected with a voice chip (4); and one output end of the voice chip is configured to output assigned voice to a voice amplifying circuit (5). Signals are inputted to the single chip microcomputer through the key array at the input end, the single chip microcomputer is configured to perform various logic processings according to the signals inputted by the keys, and control the display circuit and the voice circuit to output corresponding display data and voice, therefore the synchronization of voice and data is achieved.
Description
technical field [0001] The invention generally relates to a police device, in particular to an LED police light device with voice. Background technique [0002] In the on-duty business of the police handling the scene, there is only a police light device above the police car, and there is no voice prompt device on the police car. If it is necessary to shout, it is usually shouted by the police with a loudspeaker. Due to the personal reasons of the police, sometimes in Some personal emotions, or accents, or dialects are included in the shouting, which leads to poor shouting effect. In serious cases, it will cause disputes and affect the effect of duty. Therefore, some voices are standardized, and the voice device is installed on the police car as the equipment for the police. Change the existing police equipment, and the color expression of the police lights is not very rich, and needs to be improved. Contents of the invention [0003] The purpose of the present invention ...
