Speaker arrangement structure for vehicle

Abstract

The purpose of the present invention is to provide a speaker arrangement structure for a vehicle, the speaker arrangement structure being capable of transmitting sound (port playback sound) that is played out from a port opening to a cabin, suppressing the falling of mud or water on the port opening, and suppressing the generation of wind noise caused by the flow of air exiting from the port opening. In the speaker arrangement structure, a port opening portion (46) communicating with internal spaces (S2, S3, S4) of the speaker box (40) is provided in a front side surface portion (42i) of the speaker box (40) to form a space portion (70) surrounded by the front side surface portion (42i) of the speaker box (40), the dash panel (37), the hinge column (30), and the partition member (50), and the space portion (70) communicates with a passenger space above or below the space portion (70). The size (L2) of the space (70) in the front-rear direction from the port opening (46) is set to be at least larger than the maximum size (L1) of the port opening (46).

Description

technical field [0001] The present invention relates to a loudspeaker arrangement structure for a vehicle. Specifically, it relates to a loudspeaker arrangement structure for a vehicle comprising: left and right paired hinge pillars extending in the vertical direction of the vehicle; A dash panel at the front of the paired left and right hinge pillars; a speaker box with a closed interior space that accommodates a speaker and is fixed at the lower portion of the hinge pillar; and a partition member located inside the speaker box in the vehicle width direction. Background technique [0002] As disclosed in Patent Document 1, there is conventionally known a structure in which a speaker box is provided at the position of the occupant's feet on the hinge pillar. [0003] If the above-mentioned speaker box is a bass reflex type speaker box, the above-mentioned hinge pillar is generally covered by the side trim, so if the port opening is arranged toward the interior of the cockpit...

AI Technical Summary

Problems solved by technology

Therefore, the transmission of the port playing tone to the cabin is suppressed

[0004] In addition, in order to prevent the speaker box from compressing the cabin, if the cabin inner side of the speaker box and the side trim are arranged in a close state, and the port opening is arranged to face the cabin interior as described above, the air coming out of the port opening will Wind noise flows in the narrow space between the cabin side of the speaker box and the side trim

[0005] In order to transmit the sound played by the above-mentioned port to the cabin and prevent wind noise, it is conceivable to install a grille as a lattice structure on the side trim, but since the above-mentioned speaker box is arranged at the foot of the occupant, there may be mud or water falling on the port opening Ministry, the new problem of induced loudspeaker failure
