Embodiment Construction

[0041] A built-in audio system of a flat panel TV, as shown in Figures 1, 2, 3, and 4, what the audio system uses is a two-way frequency-dividing labyrinth phase-inverted sound box, which includes a loudspeaker, a frequency divider, a guide tube, and a box body 1 , Tweeter 3, woofer 4 and built-in BBE electronic adjustment system. The audio system uses a two-way labyrinth phase-inverted speaker.

[0042] As shown in Figures 1, 3 and 4, the structure of the cabinet 1 is manufactured according to the internal space and capacity requirements of the video equipment, and it is a special-shaped cabinet. The special-shaped surface of the special-shaped box matches the special-shaped structure in the flat-panel TV, and the special-shaped box is fixed to the special-shaped structure, which can reduce the space occupied by the special-shaped box. The special-shaped box includes a front frame 11 and a rear cavity 12 fixedly connected by screws, and a buffer pad with an anti-vibration ef...

Abstract

The invention discloses a built-in sound system for thin video equipment, which uses two-fractional frequency labyrinth inverter speaker, and includes the loudspeaker, frequency divider, pilot pipe, box, althorn and sackbut. The structure of box is produced based on the internal space of video equipment and capacity requirement, and the labyrinth pilot pipe is installed on the wall of box cavity. In this invention, maze pilot pipe forms a longer bass channel in the box, to make the bass reflex in the channel for many times and double the strength, then after the collision reflection of the wall and desk, the air audio pressure is enhanced greatly, to achieve a HI-FI sound.

Description

technical field [0001] The present invention relates to a built-in sound system of thin video equipment. Background technique [0002] With the development of society and technology, thin video devices, such as flat-panel TVs and notebook computers, are favored by consumers because of their clear picture, thinness and small footprint. The traditional concept is that video equipment is used to watch programs, resulting in the sound quality performance of many brand video equipment, only using ordinary speaker units and simple technical processing. At the same time, as the requirements of existing consumers continue to improve, more and more consumers hope for a thin-shaped video device that not only advocates high-quality picture quality, but also needs a sound system with professional sound effects. There are large-scale video equipment with professional sound effects on the existing market, but the existing thin-shaped video still has the disadvantages that the low-frequen...
