Loudspeaker arrangement for producing low frequencies - has flexible acoustic conduit connecting speaker diaphragm to air via predetermined length

摘要

The arrangement includes a loudspeaker coupled to a tube forming an acoustic load. The tube is flexible and has one end abutting the face of the loudspeaker, and is coiled around with the other end free. The length of the tube is half a wavelength for the sound which is to be partic. augmented by the arrangement. A seal ensures a tight connection between the loudspeaker and the tube. The coupling may also include deflectors in order to ensure that the maximum acoustic pressure is applied to the tube. The system enables an increased stereophonic image to be produced by more adequate reproduction of low frequency (less than 100 Hz) notes.
