摘要： One form of an in-vehicle sound emitting device includes a front case and a rear case. The front case is partitioned from the rear case by a partition plate made from a metal plate. Rear space inside the rear case is sealed, and an electronic circuit is disposed in the rear space. A loudspeaker is mounted in front space inside the front case. By using two of the partition plates having the same structure, the front case having the incorporated loudspeaker and the rear case having the incorporated electronic circuit can be disposed separately.
