A sound prompt and alarm system based on a car audio system

Abstract

The invention discloses a sound prompt and alarm system based on a car audio system. A car reversing radar sends a detection signal to a car meter, and the meter sends an alarm signal to the sound through CAN, and the sound uses a loudspeaker to give an alarm. Under the premise of not changing the current electronic structure and increasing the cost, the present invention uses the in-vehicle entertainment system to alarm related sounds, and the in-vehicle audio system has better speaker effects and DSP sound effect processing software with a larger adjustable range. To remind the driver at the same time, make the sound softer, sweeter and more pleasing to the ear. Different alarm functions are alarmed by speakers in different positions. Users can easily determine which functional module has a problem and is sending out a warning / prompt sound. At the same time, it can reduce the probability of accidents caused by frequent lowering of the driver's head.

Problems solved by technology

The unfavorable factors of the car buzzer alarm are many and complex, narrow space, irregular objects, complex environment (noise, vibration, car materials, etc.) limited by the shape of the instrument), more importantly, the listening position is not good, left, right, etc., and the alarm frequency is less, which affects the user's experience of the sound alarm

In addition, the speakers used in the combination instrument are generally very small, and cannot present a soft and pleasant alarm effect, especially some instruments use the Buzzer buzzer alarm, and the alarm sound is not effective. When such an alarm is made, it is often in a high degree of tension, and because the alarm with poor sound quality is likely to bring a sense of irritability and changes in mood and mentality to the driver, thereby affecting driving safety
