Embodiment Construction

[0041] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0042] The invention proposes a sound effect adjustment method, which is applied to an electronic device with a sound output function.

[0043] refer to figure 1 , figure 1 It is a flowchart of an embodiment of the sound effect adjustment method of the present invention.

[0044] In this embodiment, the sound effect adjustment method includes the following steps:

[0045] S10: Divide the volume of the electronic device into preset intervals;

[0046] S20: According to the corresponding relationship between the audio frequency response curve and the electrical frequency response curve, the audio frequency response curve and the standard sound pressure curve of each preset interval segment, obtain the gain value and Q value of each preset interval segment at the corresponding frequency point;

[0047] S30: Adjust th...

Abstract

The invention provides a sound effect adjusting method and device and a television set. According to the sound effect adjusting method, through dividing the volume of electronic equipment into preset intervals, according to the corresponding relation between an audio frequency response curve and an electric frequency response curve and the relation between the audio frequency response curve and a standard sound pressure curve of each preset interval, the gain value and Q value of each preset interval at a corresponding frequency point are obtained, the compensation of the gain value is carried out on a frequency band range where the corresponding frequency point of each preset interval is located according to the Q value, problems of amplitude limiting distortion and dynamic range shortage caused by a condition that different volumes output a same power in a large volume are effectively improved, and thus a sound effect with increased loudness and no distortion can be continuously obtained when the volume of electronic equipment is increased to the maximum.

Description

technical field [0001] The invention relates to the technical field of equalizer adjustment, in particular to a sound effect adjustment method, device and television. Background technique [0002] Usually the sound pressure curve of the speaker is relatively flat, but after matching the speaker and structure, the sound frequency response of the whole machine will change, the sound pressure of some frequency points will increase, and the sound pressure of some frequency points will decrease. In order to make the sounds in each frequency domain perceived by the human ear have equal loudness or balance the sound components, it is necessary to keep the audio frequency response of the whole machine flat in the entire range. The conventional method is to choose positive and negative compensation for each fluctuating frequency at the volume of 50. This method only makes the sound of the whole machine have a good sound effect at the volume of 50 and below, and is limited by power am...
