Problems solved by technology

[0007] 1. The traditional car audio system cannot automatically increase or decrease the volume during the gradual acceleration of the vehicle, so the driver needs to manually control the volume, which distracts the driver's attention and reduces the safety of the vehicle.
[0008] 2. Traditional audio cannot automatically lower the volume when someone is talking or answering the phone while the vehicle is driving, so as to maintain the intelligibility of the conversation in the car
[0009] 3. When the traditional audio is played in the vehicle, it does not consider the change of the sound quality caused by the change of the environment in the car space

Embodiment 1

[0059] The in-vehicle intelligent processor obtains and processes signals according to the noise generated by other devices while the vehicle is running.

[0060] Other equipment when the vehicle is running includes the air conditioner and the on-board ventilation system in the vehicle. The main noise of the air conditioner and the on-board ventilation system in the vehicle comes from the speed of the air conditioner fan. A fan speed detector is installed at the fan circuit, and the speed data is fed back after detection. In the intelligent audio processing system of the present invention, the sound source can be adjusted according to the noise data monitored by the intelligent audio system.

Embodiment 2

[0062] The on-board intelligent processor can judge the difference between the sound source signal and the noise data signal monitored by the acoustoelectric transducer.

[0063] The driver of the vehicle is listening to the radio in the car. At this time, the acoustic-electric transducer detects that there is a sound in the car, and compares this sound with the sound of the sound source. During the comparison, it is found that the approximation is greater than 50% (set as a reference value) , because the sound source is the sound of the radio at this time, the vehicle intelligent processor does not regard the sound as noise data, but processes the sound as the sound source amplified effect, so the vehicle will not make any changes to the sound source.

[0064] The intelligent audio system provided by the present invention and the sound source adjustment method for the intelligent audio system are currently best promoted in the vehicle-mounted market. However, it can also be a...

Abstract

The invention relates to an intelligent audio system for a vehicle and a sound source adjustment method for the intelligent audio system. The intelligent audio system comprises an on-board diagnosis (OBD) system, pressure sensors, acoustical-electrical transducers, a sound source and an on-board intelligent processor, wherein the pressure sensors with data detectors are arranged on the back surfaces of surface layers of vehicle seats, and sense pressure on the vehicle seats; the data detectors monitor the pressure data on the vehicle seats, and transmit the pressure data to the on-board intelligent processor; the acoustical-electrical transducers monitor noise data in the vehicle, and transmit the noise data to the on-board intelligent processor; and the on-board intelligent processor judges the noise data in the vehicle, and adjusts the sound source according to the judged noise data. Spatial changes made by passengers in the vehicle are automatically monitored, and a sound system is automatically adjusted, so that the function of enhancing tone quality is realized; and talks and voices produced when a call is made in the vehicle are automatically monitored, and changes such as reduction, closing and recovery in the sound source can be intelligently made.

Description

technical field [0001] The invention relates to an intelligent audio system used in the vehicle interior, and also relates to a sound source adjustment method using the intelligent audio system. Background technique [0002] With the rapid development of automotive electronics technology, automotive audio systems are constantly being upgraded to meet consumers' higher requirements for audio experience. For example, it supports a variety of external audio sources (such as DVD, SD card, Bluetooth, digital broadcasting, etc.); the radio reception is better; the sound effect processing is more abundant and other home audio effects. At the same time, car manufacturers and design companies hope to shorten the product development cycle and speed up the time to market, all of which put forward higher requirements for in-vehicle power amplifiers and audio processing circuits. [0003] Vehicle power amplifier and audio processing circuit is an indispensable function module in vehicle...
