Problems solved by technology

Evaluating the quality of a headset varies from person to person. Everyone has different feelings about music. High-frequency analysis, mid-frequency dynamics, and low-frequency sinking all have their own advantages, but for those who love bass and heavy bass In other words, the heavy bass of headphones is far inferior to the experience of audio

Embodiment Construction

[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0036] The present invention divides the audio signal into equal unit lengths by preprocessing the audio signal, and calculates the energy of the audio signal input to the earphone; then proceeds to feature extraction of the input audio signal, and extracts the energy of the audio signal as required For low-frequency, medium-low-frequency, and high-frequency signals, according to the range and amplitude of human hearing and vibration perception frequencies, judge the time to add vibration perception and calculate the magnitude of the vibration perception amplitude; after completing the judgment and calculation, the vibration amplitude corresponds to the time of the audio The shaft is ...

Abstract

The invention discloses a method for extracting features from songs and transforming them into tactile sensations. The audio signal is divided into equal unit lengths, the energy of the audio signal of each unit length is calculated, and then the audio frequency is adjusted according to the calculated energy of the audio signal. The signal is subjected to feature extraction, the low frequency band and the high frequency band are extracted, and the auditory perception amplitude is calculated correspondingly, and then the auditory perception amplitude calculation is converted into a vibration perception amplitude; according to the vibration perception amplitude ratio of the low frequency band and the high frequency band, the corresponding frequency range The time axis of the audio corresponding to the low frequency band in the audio frequency band is converted into a voltage command, which is sent to the vibration sensor, and the vibration sensor vibrates in response to the voltage command. In this way, the corresponding low audio frequency is converted into tactile vibration perception.

Description

technical field [0001] The invention relates to the technical field of signal processing, in particular to a method for extracting features from songs and converting them into tactile sensations. Background technique [0002] As a portable music listening device, earphones allow people to enjoy music anytime and anywhere. With the improvement of people's music appreciation level, many people have higher requirements for the sound quality of headphones. In addition to the high requirements for sound quality, the experience of music is also more and more valued. Many enthusiasts spend a lot of money to upgrade their equipment to get a better experience, especially the on-the-spot experience. The immersive feeling cannot be achieved by ordinary headphones. Evaluating the quality of a headset varies from person to person. Everyone has different feelings about music. High-frequency analysis, mid-frequency dynamics, and low-frequency sinking all have their own advantages, but for...
