Sound quality improvement for speaker of vehicle, by selecting standard sound range corresponding to detected number and positions of passengers in vehicle, then searching corresponding speaker angles and sound pressure output levels

摘要

#CMT# #/CMT# A memory table is created with data describing the most appropriate speaker angles and sound pressure output levels for each standard sound range. The standard sound range corresponding to the detected number and positions of passengers in the vehicle is then selected, after which the corresponding speaker angles and sound pressure output levels are searched from the memory table. #CMT# : #/CMT# Each speaker is then adjusted to satisfy the searched speaker angles and sound pressure output levels. #CMT#USE : #/CMT# For speaker of vehicle. #CMT#ADVANTAGE : #/CMT# Ensures optimum sound quality in the vehicle by detecting the number, position, and height of passengers, and adjusting the mounted angles and positions of the speakers. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows the flowchart for executing a speaker angle adjustment.
