Voice prompt and alarm system based on vehicle-mounted sound system

Abstract

The invention discloses a voice prompt and alarm system based on a vehicle-mounted sound system. An automobile reversing radar sends detection signals to an automobile instrument, the instrument sends alarm signals to a sound device through a CAN, and the sound device carries out alarming through loudspeakers. On the premise of not changing a current electronic frame and not increasing cost, an entertainment system in an automobile is used for carrying out relevant voice alarming, the vehicle-mounted sound system has the better loudspeaker effect and is provided with DSP sound processing software with the wider adjustable range, a driver is prompted, and meanwhile sounds are softer, more sweet-sounding and more beautiful. The loudspeakers at different positions carry out alarming to achieve different alarming functions, and a user can easily judge which function module breaks down and gives alarming / promoting sounds. Meanwhile, the probability that the driver frequently lowers the head to cause accidents can be reduced.

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
