Problems solved by technology

[0002] As a means of transportation, automobiles are fully enclosed compared to other means of transportation such as motorcycles, battery cars, and bicycles. Tragedy of parent's negligence, child's death by mistakenly locking child in car
After analysis, the main reason is that the sound insulation effect in the car is better after the car is turned off and locked. Broken car window escape, due to the fully enclosed design of the car, the sound of the people inside the car will not be transmitted to the outside of the car, which will easily cause tragedy, especially for cars with large passenger capacity such as school buses and travel buses. , the consequences are unimaginable

Abstract

The invention, which relates to the emergency call field, particularly provides an emergency call device that can be applied to an automobile. The emergency call device comprises a switch, a microphone, a loudspeaker, and a warning lamp. The loudspeaker and the warning lamp are arranged outside the automobile; and the switch and the microphone are arranged inside the automobile. The microphone and the loudspeaker are coupled; the switch is connected with the microphone and the loudspeaker electrically; and the warning lamp and the microphone are electrically connected. According to the device, the microphone can collect the sound inside the automobile; the sound collected by the mcirophone is amplified by the loudspeaker coupled to the microphone and then is transmitted outside the automobile; and meanwhile, the warning lamp carries out warning to attract the attention of people outside the automobile, thereby achieving an objective of calling for help. The provided device has advantages of simple structure, easy production and high practicability; and the probability of rescue of the trapped people can be increased.

Description

technical field [0001] The invention relates to the field of emergency calling, in particular to a calling device. Background technique [0002] As a means of transportation, automobiles are fully enclosed compared to other means of transportation such as motorcycles, battery cars, and bicycles. The negligence of the parents, the tragedy of locking the child in the car by mistake, resulting in the death of the child. After analysis, the main reason is that the sound insulation effect in the car is better after the car is turned off and locked. Broken car window escape, due to the fully enclosed design of the car, the sound of the people inside the car will not be transmitted to the outside of the car, which will easily cause tragedy, especially for cars with large passenger capacity such as school buses and travel buses. , the consequences are unimaginable. At this time, it becomes an urgent problem to promptly and effectively feed back the distress information in the car...
