Embodiment Construction

[0011] The present invention is a method for improving the sound field of a TV. By utilizing the function of EQ adjustment of the TV, aiming at the two installation and use situations of the LCD TV hanging on the wall or being placed in the TV cabinet, different sound systems suitable for the LCD TV are set respectively. curves, and then save them in different modes. After the user purchases the machine, he can use the remote control to set it according to different specific situations such as hanging on the wall or placing it in a TV cabinet, and then the ideal sound effect can be obtained.

[0012] see figure 1 As shown, the present invention uses the AP test system to test an audio frequency response curve. First, the frequency sweep signal is sent from the AP system to the TV, and after the audio processing of the TV, it is output from the speaker. The microphone receiving head receives the sound signal, converts the sound signal into an electrical signal, sends it back ...

Abstract

The invention discloses a method for improving the sound field of a TV. The method comprises the following steps: a sound frequency response curve is tested out by an AP test system; the sound frequency response parameter curve tested out by the AP test system is adjusted to be relatively flat by EQ function of the TV, so as to obtain better sound effect; the parameter of the adjusted EQ curve issaved to a mode and set to a state which is cured in a software and called by users according to the practical service condition. Different curves suitable for an LCD TV sound system are respectivelyset for two arrangement situations of the LCD TV, wall mounting or positioning on a TV stand, by the EQ adjustment function of the TV, and then saved as different modes, thus causing the users to obtain suitable sound field effect when the LCD TV is hung on the wall or arranged on the TV stand.

Description

【Technical field】 [0001] The invention relates to the technical field of consumer electronics, in particular to a method for improving the sound field of a TV. 【Background technique】 [0002] With the development of LCD TV technology, LCD TVs have begun to be more and more popular among ordinary consumers. At the same time, traditional color tube TVs tend to be eliminated. At present, there are generally two installation methods for LCD TVs in users' homes, namely: wall-mounted installations and ordinary placement on TV cabinets. However, when the LCD TV is hung on the wall and placed on the TV cabinet, the positions of the speakers in the two placement methods are different for the user, so the sound field is also different when the user uses it, so that the sound effect when the user listens There will be some differences. Although there are various curves adjusted inside the LCD TV to adapt to various signal sources, such as music, movies, news and so on. However, ther...
