摘要

The device has a hollow body (10) divided into a set of spaces (14a, 14b) by an acoustically inactive wall (12). A sound transmitting device (16) includes a set of vibratable elements (20a-20b) dividing the spaces (14a-14b) into a set of subspaces (18a-18d). The space (14b) is acoustically coupled with an inner space of a motor vehicle and/or a space surrounding a vehicle over a sound outlet (24). The subspace (18b) includes a switchable separator (28) that divides the subspace (18b) into a set of partial spaces (30a-30b) for adjustment of a sound transmission.
