DSP sound system and sound system acoustic automatic test method

Abstract

The invention relates to a DSP sound system and a sound system acoustic automatic test method, the DSP sound system comprises a microphone module, an execution module, an analog-to-digital conversion module, a DSP digital signal module, an MCU control module, a digital-to-analog conversion module, a power amplifier module and a loudspeaker module, the DSP digital signal processing module is used for testing a digital audio signal and forming a test result; the MCU control module outputs a control signal according to a test result and controls a sound system to adjust parameters, the digital-to-analog conversion module is used for converting a digital audio signal into an analog audio signal, the power amplifier module is used for amplifying the analog audio signal, and when the loudspeaker module receives the analog audio signal, the loudspeaker module plays sound. According to the invention, the acoustic test efficiency of the sound system is improved, the sound system has a better sound listening effect, and the acoustic test of the sound system can be conveniently completed by general users.

Description

technical field [0001] The present application relates to the technical field of audio system debugging, in particular to a DSP audio system and an automatic acoustic testing method for the audio system. Background technique [0002] With the technological development of audio systems, users have higher demands on intelligent audio systems. In order to achieve the best listening effect of the audio system in the audio room, it is usually necessary to perform an acoustic test on the audio system before using the audio system, and then adjust the audio system to achieve the best music playback effect. [0003] Most of the existing audio systems are composed of multiple speakers. At present, the acoustic test method of the audio system composed of speakers requires professional tuning engineers to adjust various parameters of the speakers in the audio system. The acoustic effect of the system, repeatedly adjust the parameters of each speaker, so that the sound system can achie...

Problems solved by technology

The operation process of the acoustic test method of the sound system is complex and cumbersome, and the amount of engineering is large, and there are many factors that affect the sound effect of the sound system. In many cases, in order to save test time, which parameters to adjust the sound system are judged by the experience of professional engineers. For the acoustic test of the home audio system, it is almost impossible for non-professionals to perform the acoustic test of the audio system. Therefore, the existing acoustic test method of the audio system cannot be applied to the general users, and the acoustic test results of the audio system are directly It affects the listening effect of the audio system playing music. When the acoustic test effect of the audio system is not ideal, it is easy to cause the user to use the audio system to have poor listening effect.
