ない。Problem to be Solved by the Invention However, with the conventional speaker device shown in FIG.
Since the sound pressure level is higher and the response time is faster than the response from the left channel speaker 17 passing through A, the localization of the sound image is largely biased to the right, making it impossible to obtain a natural stereo feeling.

音場はより不自然なものとなってしまう。In order to solve the above problem, an attenuator and a delay means are used to optimize the sound pressure level and time response from the right channel speaker 16 to be equal to the response from the left channel speaker 17 in the driver's seat. However, the left and right responses in the passenger seat 6 at that time are greatly different in sound pressure level and arrival time, and the sound field reproduced in the passenger seat 6 becomes even more unnatural.

するように設置されている。In FIG. 1, speakers 1 to 4 all have rectangular diaphragms that are elongated in the horizontal direction. Generally, the directional characteristics of sound emitted from a long and narrow rectangular sound source become sharp in the longitudinal direction of the sound source. Therefore, by elongating the shape of the diaphragm of the speakers 1 to 4 in the horizontal direction, the directivity characteristics can be controlled and the area from which the sound of each speaker is radiated can be limited. Therefore, in this embodiment, the speakers 1 and 3 are installed so that they radiate sound from the left and right front pillars 8 toward the side window 7, and the reflected sound reaches only the listening points A and 3, respectively. The speakers 2 and 4 are installed so as to radiate sound from the corners of the front end of the side window 7 to the listening points A and B, respectively.
