Abstract

Interior rearview mirror for motor vehicles

Interior rearview mirrors for motor vehicles are known in whose mirror housing is arranged a speaker. However, the sound they produce frequently does not satisfy sound quality requirements in motor vehicles.

So that the interior rearview mirror ensures high quality of sound reproduction from its speaker while being easy to assemble, the speaker is part of a bass reflex system that is accommodated in the mirror housing. The result of this design is optimum sound quality. The bass reflex system can simply be built into the mirror housing with no additional installation space required.

The interior rearview mirror is installed in motor vehicles.
