  • On-vehicle acoustic device and method of assembling the same
    Patent number: 8776944
    Abstract: An opening is formed in a ceiling lining of a vehicle cabin part. The diameter of the opening in the ceiling lining is smaller than a diameter of a speaker, which has a frame. The speaker is disposed at the opening, and a fixing screw is inserted into a fixing aperture formed in a central part of the speaker. A fixing screw is screwed to a screw hole formed in a reinforcing brace positioned at an inner side of a top plate proximate the ceiling of the vehicle. A central part of the speaker is fixed to the reinforcing brace while a circumferential periphery of the frame is pressed against a peripheral edge of the opening in the ceiling lining via a frame interposing material.
