Embodiment Construction

[0020] Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used throughout the drawings to refer to the same or like parts.

[0021] The present invention includes microphones installed at various positions of a listener seated in a vehicle, and analyzes sound input through a microphone selected by the listener, and automatically controls volume level and sound image of sound output through a speaker.

[0022] In addition, the present invention receives a listener position signal caused by a seated listener, and upon receiving said listener position signal, reads the pre-set volume and sound image information of each loudspeaker according to the listener position, and according to The read information automatically controls the sound output through the speaker.

[0023] The construction and operation of the sound equalization system...

Abstract

A vehicle acoustic system with a plurality of speakers and a control method thereof are provided. The system includes a plurality of microphones installed at a listener position, and outputting an audible sound; a position selector for selecting one of audio signals; an audio measurement unit for analyzing the audio signal and generating signal level and sound image information; an audio signal generator for generating audio data; a digital signal processor for controlling a signal level and a sound image of the audio data, converting the audio data into an audio signal, and outputting the converted audio signal; and a microcomputer for receiving the signal level and sound image information, and comparing the received signal level and sound image information with previously stored reference signal level and sound image information.

Description

technical field [0001] The present invention relates to a vehicle sound system, and more particularly, to a vehicle sound equalization system and a control method thereof for allowing listeners on board to perceive sound imaging and sound images according to their positions in the vehicle. Background technique [0002] Generally, vehicles are basically equipped with sound systems. The vehicle sound system includes a vehicle audio, and front left speakers (FL), front right speakers (FR), rear left speakers (RL) and rear right speakers (RR) installed at an upper portion of a dashboard in the vehicle. [0003] Audio signals from the respective left and right speakers, that is, FL and FR (or RL and RR) are set to have the same output level. However, in terms of vehicle structure, a listener sitting in the vehicle sits on an asymmetrical seat between the speakers. For example, the driver has a seat biased toward said FL and the passenger has a seat biased toward said FR. There...
