Vehicle-mounted audio prompting device and system

Abstract

The invention discloses a vehicle-mounted audio prompting device and system. The device comprises a signal receiving module, a microprocessor module, an audio decoding module, a power amplifier selection module and a power amplifier module; the signal receiving module receives an input signal; the signal receiving module is connected with the microprocessor module so as to send the processed inputsignal to the microprocessor; the microprocessor is connected with the audio decoding module so as to perform audio data transmission according to the processed input signal; the microprocessor is connected with the power amplifier selection module so as to select a corresponding power amplifier module and a corresponding sound channel according to the processed input signal; the audio decoding module is connected with the power amplifier module so as to decode the audio data and send the decoded audio data to the selected power amplifier module; and the power amplifier module is connected with the corresponding loudspeaker according to the selected sound channel so as to carry out audio prompt. Various audio prompts can be integrated, repeated waste is removed, the installation positionis optimized, wiring is reduced, and the fault probability and the maintenance cost are reduced.

Description

technical field [0001] The invention relates to the field of vehicle technology, in particular to a vehicle audio prompt device and system. Background technique [0002] In the prior art, there are many kinds of audio prompting devices on automobiles, including overspeed alarms, seat belt alarms, high temperature alarms, back-up alarms, and exit bells. Each audio prompt device includes a power processor, a signal receiving device, a power amplifier, an audio processing unit, a speaker, etc., resulting in repeated waste of parts such as a power processor, a signal receiving device, a power amplifier, an audio processing device, and a speaker. With more and more types of audio prompts, multiple installations and wiring in the limited space of the car will inevitably bring a heavy workload, and increase the probability of failure and maintenance costs. In addition, since various audio prompting devices are arranged separately, in terms of audio, the types of sounds and prompti...

AI Technical Summary

Problems solved by technology

Each audio prompt device includes a power processor, signal receiving device, power amplifier, audio processing, speaker, etc., which causes repeated waste of components such as power processor, signal receiving device, power amplifier, audio processing, and speaker

With more and more types of audio prompts, multiple installations and wiring in the limited space of the car will inevitably bring a heavy workload, and increase the probability of failure and maintenance costs

In addition, since various audio prompting devices are arranged separately, in terms of audio, the types of sounds and prompting sounds do not form certain rules, which may cause some sounds to be the same or similar, making it difficult for drivers and passengers to distinguish

Further, since various audio prompt devices have no distinction between primary and secondary, each broadcasts its own prompt sound, which may cause sound overlap, making it difficult for drivers and passengers to distinguish
