Abstract:
An acoustic transducer with an acoustic element that emits or receives front-side acoustic radiation from its front side, and emits or receives rear-side acoustic radiation from its rear side. A housing directs the front-side acoustic radiation and the rear-side acoustic radiation. A plurality of sound-conducting vents in the housing allow sound to enter the housing or allow sound to leave the housing. A distance between vents defines an effective length of an acoustic dipole. The housing and its vents are constructed and arranged such that the effective dipole length is frequency dependent.

Claim (Index 15):
A loudspeaker, comprising:\n first and second acoustic drivers that each emit front-side acoustic radiation from a front side of the driver and rear-side acoustic radiation from a rear side of the driver; a housing that comprises a rear acoustic volume that receives the rear-side acoustic radiation of both drivers and a front acoustic volume that receives the front-side acoustic radiation of a driver; a plurality of sound-emitting openings in the housing, wherein a distance between sound-emitting openings defines an effective length of a loudspeaker dipole, and wherein the housing and its sound-emitting openings are constructed and arranged such that the effective dipole length is frequency dependent wherein the effective dipole length is larger at lower frequencies than it is at higher frequencies; wherein first and second rear sound-emitting openings are acoustically coupled to the rear acoustic volume and wherein first and second front sound-emitting openings are acoustically coupled to the front acoustic volume, wherein the first rear sound-emitting opening is closer to the first front sound-emitting opening than is the second rear sound-emitting opening; a resistive screen covering the first rear sound-emitting opening; and an acoustic transmission line that is acoustically coupled to the rear acoustic volume and comprises the second rear sound-emitting opening.
