A loudspeaker radiating diaphragm can be stiffened to help increase the breakup frequency to above the working frequency range of the driver concerned, by forming it of a moulded part and an attached formed part. The moulded part is a radiating surface with stiffening ribs. The formed part is a thin surface of high modulus material, attached to the rear of the ribs. The overall structure can have significantly higher stiffness than either of the two parts. This helps in designing a loudspeaker driver that does not breakup within its working frequency range. 1.

Acoustic enclosure for loudspeakers

Acoustic enclosure for mounting loudspeakers ( 1 ) that contains a certain number of curved-profile guides ( 8 ) arranged radially beside one another at a specific distance and forming a ring ( 7 ), between which the sound from the loudspeaker is propagated from the central space ( 6 ) to the outer ring ( 9 ), which it enters obliquely as a result of the curvature of the guides. Since said ring ( 9 ) contains no elements against which the sound can be reflected back into the conduits, it works like a closed circuit or track that the sound passes through until it is exhausted, keeping the inner face of the membrane of the loudspeaker free of disturbances that, in conventional enclosures, are caused by the reflected sound when it hits the membrane during the lifetime of the sound, thereby eliminating the distortion and alterations of the natural response linearity of the loudspeaker from this source.
