Liquid crystal television bass boost system

Abstract

A liquid crystal television bass boost system comprises a front frame, a rear cover, a screen and a vibration speaker, wherein the vibration speaker is fixed to the front frame through a speaker support, the vibration speaker and the speaker support are fixedly connected through a spring cushion, an elastic cushion is installed on an vibration head of the vibration speaker, a metal plate is arranged between the rear cover and the vibration speaker and is fixed to the rear cover, and the metal plate and the vibration head of the vibration speaker are connected tightly through the elastic cushion. By the aid of the system, a flat television has good bass effect under the condition that the thickness of a mainframe is not changed.

Description

technical field [0001] The invention belongs to the field of household electrical appliances, in particular to a TV shell structure with a bass sound device. Background technique [0002] At present, China's color TV industry is developing rapidly. Color TV products of different brands and specifications developed by various manufacturers have their own styles and characteristics. It contains rich low frequency, rich and powerful tone, and strong stereoscopic effect. It sounds very popular. The existing subwoofer forms are as follows. The first type is to directly fix the speaker on the rear shell without a cavity. The effect is very poor, basically can not reflect the effect of the bass; the second type is the built-in subwoofer, the audio part is installed in the casing, the typical Toshiba rocket launcher, it is in the casing, above the picture tube, horizontal A speaker with a built-in speaker is cylindrical in shape and long.

[0002] At present, China's color TV industry is developing rapidly. Color TV products of different brands and specifications developed by various manufacturers have their own styles and characteristics. It contains rich low frequency, rich and powerful tone, and strong stereoscopic effect. It sounds very popular. The existing subwoofer forms are as follows. The first type is to directly fix the speaker on the rear shell without a cavity. The effect is very poor, basically can not reflect the effect of the bass; the second type is the built-in subwoofer, the audio part is installed in the casing, the typical Toshiba rocket launcher, it is in the casing, above the picture tube, horizontal A speaker with a built-in speaker is cylindrical in shape and long. Although it is better than the first type of speaker, it leads to a bulky cabinet. Because the volume of the speaker in the cabinet is also limited, the diameter of the speaker is also relatively large. Small; the third type is the top-mounted type, which installs the speaker part on the top of the TV casing. Typical brands include Sony and Panasonic. It is a flat box placed on the top of the rear casing. This structure has high cost and low volume. It cannot be made bigger. Although it has a certain bass effect, its shape is irregular and it is easily affected by the outside world, which also affects the sound quality.

These three categories have their own deficiencies that need to be improved, especially in recent years with the development of liquid crystal technology, TVs have become thinner and thinner, and ordinary speakers cannot fit, let alone woofers or larger ones. The subwoofer, and even if it is hard-installed, it will make the appearance very ugly. For this reason, many manufacturers have worked hard in this area and invested a lot of research and development, but a more troublesome problem is that the acquisition of bass requires a relatively large speaker. The vibration surface, or a relatively large amplitude, is in conflict with the development of ultra-thin LCD TVs, so we need to adopt new technologies to solve the problem.
