Embodiment Construction

[0011] As shown in the figure: the woofer unit 2 provided on the speaker casing 1 is provided with a conduit 9 connected at both ends in the speaker casing 1, and the sound outlet 4 of the conduit 9 is on the side close to the woofer unit 2, The sound inlet opening 8 of the duct 9 is on the side away from the woofer unit 2, the sound inlet opening 8 of the duct 9 communicates with the inner cavity 7 of the sound box housing 1, and the inner cavity 7 is also communicated with the woofer unit 2, the duct The orientation of the sound outlet opening 4 of the duct is consistent with that of the woofer unit 2, and the sound outlet opening 4 of the duct is connected to the outside air.

[0012] The sound outlet opening 4 of the duct 9 is preferably arranged on the side directly below the woofer unit 2 and close to the woofer unit 2, and the sound inlet opening 8 of the duct 9 is preferably arranged directly below the woofer unit 2 and away from the woofer unit. Unit 2 side. One side...

Abstract

The invention is composed of two speaker units and a canal with the shape like Chinese character 'hui', and can be mounted in flat panel TV system. A woofer is located on the case of the sealed speaker box; an canal is located in the case; the sound-outgoing opening of the canal is located at the side near the woofer, and the sound-incoming opening of the canal is located at the side apart from the woofer; the sound-incoming opening of the is connected to the internal chamber of the speaker box; the sound-outgoing opening of the canal faces a direction identical with the woofer; the sound-outgoing opening of the canal is connected to air out of the box.

Description

technical field [0001] The invention relates to a thin sound box, in particular to a thin integrated loudspeaker system which is composed of two loudspeaker units and has a loop-shaped conduit and can be built into a flat-panel TV system. Background technique [0002] Now the speaker system design of LCD, PDP and other flat-panel TVs, small-sized flat-panel TVs generally use two full-band speaker units, and use the volume of the TV casing as the cavity to form a stereo or virtual surround sound system; large-sized flat-panel TVs , a pair of speaker systems are used, which generally consist of a mid-bass speaker unit and a tweeter unit. The first solution has poor sound quality and is suitable for low-end flat-panel TV design; the second solution has good sound quality, but because the cavity volume of its speaker system is limited by the overall structure of the flat-panel TV, coupled with the limitation of the speaker unit itself, the low-frequency expansion poor. Conten...
