Embodiment Construction

[0040] Features described with reference to different embodiments may be combined with another feature, if they are not mutually substituted. For example, that is to say, elements described in accordance with one embodiment, such as phase correction elements, various chambers, and resonators, and their characteristics also apply to corresponding elements and characteristics in another embodiment.

[0041] attached Figures 1 to 4An exemplary embodiment of a loudspeaker system 100 is shown schematically with varying illustrations. The speaker system 100 includes a speaker enclosure 10 forming a first enclosure chamber 20 and a second enclosure chamber 30 . The woofer 50 is installed on the partition plate 40 that separates the first cabinet chamber 20 and the second cabinet chamber 30 .

[0042] For example, the speaker enclosure 10 has a width W in the Y direction, a height H in the Z direction, and a depth T in the X direction. W, H and T are each larger than 20cm, 40cm, 6...

Abstract

A loudspeaker system has a loudspeaker housing that comprises at least a first and a second housing chamber. The loudspeaker system has a bass loudspeaker that is mounted on a partition between the first housing chamber and the second housing chamber, wherein the back of the bass loudspeaker has the first housing chamber present and the front of the bass loudspeaker has the second housing chamber present. The partition contains at least one bass reflex opening. A phase correction element is arranged at the front of the bass loudspeaker in the second housing chamber. The bass reflex opening opens into the second housing chamber and is arranged in a region adjacent to the phase correction element.

Description

technical field [0001] The present invention relates to a bass reflex loudspeaker system having a phase correcting element. Background technique [0002] Bass reflex loudspeaker systems are frequently used in audio engineering. In a bass reflex speaker system, the speaker cabinet is not closed, but has channels leading to the outside. Vents or ventilation systems are also used. The sound element emits sound from the rear of the speaker to increase the efficiency of the speaker system in its resonant frequency region. This makes possible a significant increase in sound pressure levels and a significant extension of the power bandwidth. [0003] It is known practice to use multi-room loudspeaker systems. In a multi-chamber loudspeaker system, the individual chambers interact with each other as resonators. [0004] Furthermore, it is known practice to equip loudspeakers with something called a phase plug. Phase plugs are phase correcting elements with a reduced number of ...
