Acoustic-optical matching system and method

Abstract

The invention discloses an acoustic-optical matching system which comprises a conversion module used for converting an audio signal to frequency components of different frequency points of a frequency domain, a sorting module used for sorting each frequency component, a value-taking module used for taking a value with the highest amplitude from a result after sorting as an audio feature value, a comparison module used for comparing the audio feature value and multiple groups of to-be-selected light-emitting feature vectors, a selection module used for selecting one group of light-emitting feature vectors which are the same as or are most similar to the audio feature value from the groups of to-be-selected light-emitting feature vectors, and a display module used for displaying the light-emitting feature vectors. According to the acoustic-optical matching system and method, the light and the audio frequency are matched, so that the pleasant feeling can be improved, or people can feel relaxed, and furthermore, when the people have high pressure, listening more to sounds at the specific frequency helps to relieve the pressure.

Description

technical field [0001] The invention relates to the field of acousto-optic technology, in particular to an acousto-optic matching system and method. Background technique [0002] With the development of technology, various IoT smart devices have emerged, especially more and more products that combine Bluetooth speakers with LED lights. Bluetooth speakers can be conveniently connected to smartphones wirelessly, which can solve the needs of people to enjoy and share music; LED lighting can save energy and electricity, which can not only meet the role of lighting, but also meet people's higher-level requirements for atmosphere effects. Require. However, many products combining Bluetooth audio and LED lighting simply put together functional products in the two fields, that is, the lighting effect is stored in the memory in a fixed form, and the lighting effect is displayed in a fixed form when playing music. , this lighting effect cannot match the playing music. For example, i...

However, many products combining Bluetooth audio and LED lighting simply put together functional products in the two fields, that is, the lighting effect is stored in the memory in a fixed form, and the lighting effect is displayed in a fixed form when playing music. , this lighting effect cannot match the playing music. For example, if the playing track is a high-pitched track, the lighting effect displayed cannot highlight the high-pitched track, or when the playing track is a low-pitched track, the lighting effect displayed does not. Can't highlight the bass tracks, that is, the displayed lighting effect can't match the tone of the playing music, which will give users a sense of incongruity or dislocation from the visual and auditory experience. Therefore, the current lighting speakers cannot solve people's deeper problems. When people face pressure from various aspects and need to relax through lights, the existing products lack the real solution to eliminate the psychological and social factors such as tension, anxiety, depression, terror and other bad psychological states.
