Title: On-vehicle speaker system
Inventor: DATE TOSHIHIKO
IPC: H04R1/30
Filed: 1992-12-14
Abstract: PURPOSE:To correct a sound field in an automobile compartment by controlling reflected sound by an acoustic method by connecting one end of a sound tube whose length and cross-sectional area are different to one or plural speakers and connecting the other end to a horn shaped sound aperture part. CONSTITUTION:The response of reflected waves 1-b and 1-c is close to a time difference between both ears from the view point of its time order and acts as phase interference to a direct wave 1-a. Also, since the reflectivity of a dash board 6 or window glass 7 is high and energy attenuation by reflection is small, influence on the direct wave 1-a is large and the reflected waves 1-b and 1-c disturb the frequency characteristics of a listening position and hinder sound image localization. In regard to this, direct sound waves 3-b and 3-c radiated from the speaker 2 of an auxiliary sound source separated from a main sound source are generated at the listening position of a driver's seat 5 so as to respond to the reflected waves 1-b and 1-c. Thus, unrequired reflected waves 1-b and 1-c components can be cancelled and the frequency characteristics and the sound image localization can be improved.
