Method and system for optimizing television sound effect and television

Abstract

The invention discloses a method and system for optimizing a television sound effect and a television. The method for optimizing the television sound effect comprises the steps of receiving, through a signal receiving module, audio signals input by an information source; receiving, through a volume adjustment module, volume adjustment information input by a user, and adjusting a volume value of the television; judging, through a judging module, volume section information of the television according to the current volume value; calling, through a calling module, a corresponding frequency response curve according to the volume section information of the current volume value; performing corresponding sound effect processing on the audio signals according to the frequency response curve through a signal processing module, and dynamically calling the corresponding frequency response curve according to a volume section of the current volume value, so that audio data of different volumes is dynamically processed. The hearing of the human ears is guaranteed when output power is low, distortion or cracking voice caused by the use of the same frequency response curve when the output power is too high can be avoided, and user experience is improved.

Description

technical field [0001] The invention relates to the technical field of televisions, in particular to a method for optimizing sound effects of a television, an optimization system and a television. Background technique [0002] In the traditional TV field, the audio signal is input to the SOC chip for demodulation processing, and then output to the digital power amplifier with DSP for signal amplification and sound processing through I2S, or output to the analog power amplifier, and then passed through a specific impedance and rated power The speaker output, which is the sound that can be heard by the human ear. [0003] The traditional TV sound adjustment method is to use 0.5Vrms, 1KHz sinusoidal audio signal to adjust the volume, and when the power reaches 1W, the frequency response curve is obtained by sweeping. However, this cannot meet consumers' hearing comfort requirements for TV treble (high frequency) and bass (low frequency) at different volumes, and the adjustment...

Problems solved by technology

However, this cannot meet consumers' hearing comfort requirements for TV treble (high frequency) and bass (low frequency) at different volumes, and the adjustment of the sound curve is carried out in separate channels, and only focuses on the 0.5Vrms input amplitude at 1KHz Output power curve, under the same volume, programs under different signal sources show inconsistent sound output
