Description

Technical Field

[0001] The utility model relates to the technical field of automobile safety driving auxiliary equipment, and specifically to a decibel alarm device inside a vehicle. Background Art

[0002] The decibel meter is the most basic noise measuring instrument. It is an electronic instrument, but it is different from objective electronic instruments such as voltmeters. When converting sound signals into electrical signals, it can simulate the time characteristics of the human ear's reaction speed to sound waves; it has characteristics of different sensitivities and intensity characteristics of changing characteristics at different loudness. The decibel meter is a subjective electronic instrument. The sound level meter uses advanced digital detection technology, which greatly improves the stability and reliability of the instrument. The sound level meter has the advantages of simple operation and easy use; it has the characteristics of a large dynamic range, a large-screen LCD digital display, and automatic measurement and storage of various data. The decibel meter can be widely used in industrial noise measurement and environmental noise measurement of various machines, vehicles, ships, electrical appliances, etc. It is suitable for the sound testing field of factories, enterprises, architectural design, environmental protection, labor hygiene, transportation, teaching, medical care, scientific research and other departments.

[0003] With the popularity of online ride-hailing and smart driving cars, passengers' behaviors such as chatting loudly, playing videos and music in the car may interfere with the driver's driving safety. The traditional verbal prompting method of the driver may cause discomfort to the passengers. Therefore, it is particularly important to develop a device that can actively prompt passengers to reduce the noise in the car.

[0004] The patent specification with announcement number CN219370613U discloses a high-decibel alarm buzzer, wherein a movable frame is arranged inside the shell, the movable frame is cylindrical, a sleeve is fixedly arranged on the outer ring of the movable frame, a buffer air cushion is fixedly arranged on the outer wall on one side of the bottom of the movable frame, a buffer air ring is fixedly arranged on the inner wall on one side of the upper end of the shell close to the movable frame, and a vibration wall is arranged inside the movable frame. The utility model has the following advantages: when the buzzer body starts the alarm, the vibration wall can produce a certain resonance, thereby increasing the decibel of the sound. Similarly, when the sound is transmitted from the top of the movable frame, it can contact the protective cover to produce resonance. If the car is bumpy during movement, it can be buffered by the buffer air rings and buffer air cushions at the upper and lower ends of the movable frame respectively. This operation can effectively reduce the impact force on the movable frame when bumps occur, and the protective cover can block external dust and rain, thereby avoiding entering and contacting the internal buzzer body.

[0005] However, in the implementation of relevant technologies, it was found that the above technical solution has the following problems: the above device is not convenient for performing multiple decibel alarms and warnings in the car during use. If the prompt is inappropriate or the prompt sound is too small, it will cause friction between the occupants and the driver, making it difficult to ensure traffic safety during driving. Therefore, further improvement is needed. Utility Model Content
