Embodiment Construction

[0032] Hereinafter, the present disclosure will be described in detail with reference to the accompanying drawings.

[0033] In general, the present disclosure provides a technique of controlling sound in a vehicle in which a specific sound is synthesized by reducing roaring noise or arbitrarily generating engine sound. In order to implement the basic functions for generating engine sound and active noise control (ANC) for sound reduction, a combination of a controller and an in-vehicle microphone is required.

[0034] According to the present disclosure, a conventional controller and a room microphone are replaced by a smartphone, and the microphone installed in the smartphone is used for an error signal of noise inside the car. Also, instead of the conventional controller of the audio unit, a control algorithm is employed in the smartphone application, so that the smartphone with the microphone acts as the controller.

[0035] refer to figure 1 , The system for controlling...

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...
