Problems solved by technology

However, due to the limitation of the structure of the traditional full-range speaker box, it is impossible to obtain a good subjective listening effect with only one full-range speaker
The general design is to use a combined speaker unit, and a tweeter unit is added to a woofer unit to form a TV audio system. The disadvantage is that the structure is too large and is not suitable for new flat-panel TV designs. It is also relatively high, which does not meet the requirements of performance-price ratio of information appliances

Abstract

The present invention relates to a sound box used for loudspeakers, in particular to the television sound box of a loaded double folding type acoustic horn. A casing body is provided with loudspeakers according to the technical proposal provided by the present invention. The present invention is characterized in that the casing body comprises a middle casing body and an internal casing body, wherein the middle casing body has a bottom part and a loudspeaker shaped side wall expanding outwards, and mounting holes used for the installation of loudspeakers are arranged at the center of the bottom part of the middle casing body; the internal casing body is positioned in the middle casing body, also has a bottom part and a loudspeaker shaped side wall, the opening of the internal casing body is pointed at the bottom part of the middle casing body, and an acoustic horn cavity folded forwards is formed between the internal casing body and the middle casing body. The present invention adopts an entire frequency band loudspeaker unit, to enhance the sound pressure of the loudspeaker unit and the efficiency of low frequency band better, thus enhancing the acoustic quality of television sound boxes.

Description

technical field [0001] The invention relates to a sound box for a loudspeaker, in particular to a sound box for a TV loaded with a double folding horn. Background technique [0002] Speakers currently used in flat-panel video equipment such as LCDs and PDPs require small size, thin structure, high sound pressure, and good low-frequency expansion. However, due to the limitation of the structure of the traditional full-range speaker box, it is impossible to obtain a good subjective listening effect with only one full-range speaker. The general design is to use a combined speaker unit, and a tweeter unit is added to a woofer unit to form a TV audio system. The disadvantage is that the structure is too large and is not suitable for new flat-panel TV designs. It is also relatively high, and does not meet the requirements of the performance-price ratio of information appliances. Contents of the invention [0003] The purpose of the present invention is to design a double-foldi...
