Active noise control system and method using smartphone

Abstract

A system for controlling vehicle interior sound using a smart phone and a method thereof include a driving information provider to provide driving information while a vehicle is being driven. A smart phone includes a microphone which senses interior noise or sound of the vehicle and generates a sound control signal to diminish or amplify the interior noise based on the driving information from the driving information provider. An audio amplifier amplifies the sound control signal received from the smart phone and outputs an amplified signal though a speaker.

Description

technical field [0001] The present disclosure relates to a system and method for controlling sound in a car using a smartphone. More particularly, the present disclosure relates to a system and method for controlling in-vehicle sound using a smartphone capable of reducing or increasing in-vehicle sound and serving as a controller for controlling noise. Background technique [0002] In-vehicle sound control technology, that is, active noise control technology, is applied to an audio system or an additional controller in a vehicle to reduce in-vehicle noise or reproduce arbitrary sounds. [0003] In addition, there is a technology to implement sound settings according to user preferences in smartphone applications. For example, a system for synthesizing and reproducing vehicle sounds disclosed in Korean Patent Application Publication No. 2013-0054031 (published on May 24, 2013), synthesizing sounds reproduced and downloaded through smartphones according to user preference and...

Problems solved by technology

Since this technology simply adds the user's preferred sound to the engine noise, the combination of vehicle sounds such as engine noise and user's preferred sound can be quite uncomfortable for the driver and passengers
