Embodiment Construction

[0039] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] The present invention provides a method for sending short messages using the audio effect adjustment device of the above-mentioned TV set, referring to figure 1 , the method includes the following steps:

[0041] Step S10, preset the sound effect power table corresponding to the sound effect value and the volume power table corresponding to the volume value; in the sound effect power table, each sound effect value corresponds to a sound effect power value; in the volume power table, each volume value will be Corresponds to a volume power value. In the embodiment of the present invention, the above-mentioned steps can be realized by software. For example, in step S10, the sound effect power P can be obtained by looking up the table in the following programming language 音效1 : Power_soundeffect_before=GetPowe(u8...

Abstract

The invention discloses a sound effect adjusting method of a television, comprising the following steps of: pre-arranging a sound effect power table which corresponds to a sound effect value, and a sound volume power table which corresponds to a sound volume value; recording the sound effect value and the sound volume value before the sound effect is adjusted, and obtaining corresponding sound effect power and sound volume power from the sound effect power table and the sound volume power table; reading the adjusted sound effect value when a user adjusts a sound effect setting value; checking the table to calculate the adjusted sound effect power; comparing the sound effect power before and after adjusting the sound effect to see whether the sound effect power is changed or not; calculating a sound effect power changing value if the sound effect power is changed; calculating the adjusted sound volume power according to the sound effect power changing value; checking the table to obtain the corresponding sound volume value according to the adjusted sound volume power; and transmitting the adjusted sound volume value to a sound volume register to adjust the sound volume. The invention further provides the television and a sound effect adjusting device of the television. According to the invention, the hardware cost does not need to be increased, the output power is guaranteed to have no obvious changes, the sound distortion is reduced and the user experience is improved.

Description

technical field [0001] The present invention relates to the field of televisions, and more specifically, to a method and device for adjusting sound effects of a television, and the television. Background technique [0002] With the further improvement of the integration level of TV processing chips, the main control chip has integrated a sound effect processing module, which can perform sound effect processing such as treble (Treble) and bass (Bass). At present, the power generated by the sound effect processing part in most TV main control chips is superimposed on the power generated by the volume processing part. For example, the power before sound effect processing is P 音量 , the total power P after adjusting the sound effect (assuming that the sound effect is increased) 总功率 . From the measurement P 总功率 >P 音量 , that is, after adjusting the sound effect, the total power becomes larger. The increased power is to adjust the P produced by the sound effect. 音效 , P 音效...
