Loudspeaker with several loudspeakers - has several loudspeaker housing in common casing, each housing with preset vol.

摘要

The loudspeakers have each a housing with vibration elements in radiation mechanisms. Several housings (6, 8), each with a loudspeaker (12, 13) are enclosed in a common casing (10). Each housing has a preset vol. and surrounds one side of the vibration elements. The common casing has also a preset vol. The other side of each loudspeaker vibration element is surrounded by the casing. The housings have acoustic radiation devices (14-16) with different resonance frequencies. Pref. the common casing also extends between two housings such that two loudspeakers are located opposite each other. The common casing may be fitted round the middle region and the housings round its periphery. ADVANTAGE - Simple design and improved adaptability for acoustic frequencies.
