Bone conduction oscillator control method based on acceleration sensor, computer readable storage medium and bone conduction earphone

Abstract

The invention provides a bone conduction oscillator control method based on an acceleration sensor, a computer readable storage medium and a bone conduction earphone. The bone conduction oscillator control method comprises the following steps of: periodically utilizing the three-axis acceleration sensor to collect acceleration values of a bone conduction oscillator in X / Y / Z axes, and normalizing the acceleration values to obtain a total acceleration value A; with a fixed time length B as a boundary, accumulating the total acceleration values A collected within fixed time length B to obtain exercise intensity E1; and comparing the exercise intensity E1 with a set threshold value, and adjusting the vibration amplitude of a bone conduction vibrator based on the comparison result. According to the bone conduction oscillator control method, the bone conduction vibrator can be ensured to vibrate in a normal vibration frequency, and the condition of large vibration frequency fluctuation is avoided, so that the use experience of a user on the bone conduction earphone is improved, and the production and popularization of the bone conduction earphone are facilitated.

Description

Technical field [0001] The present invention relates to the technical field of controlling bone conduction vibration, and is mainly related to a bone conduction-controlled method of an acceleration sensor, a computer readable storage medium, and a bone conduit. Background technique [0002] At present, the oscillator is not the same as the traditional electromagnetic speaker, and the audio signal is transformed into a vibration signal via the bone conductor via the bone conductor, and the vibration signal is transmitted to the skull of the bone conduction to the listening nerve, which makes people I heard the audio, but since the bone conduction also vibrates the air, the sound waves are generated, and the sound wave is incorporated into the human ear, and the people can hear part of the audio. [0003] Based on the working principle of bone conduction, when using bone conductive earphones, it is necessary to control the vibration amplitude of the bone conduction vibrator, ensuri...

AI Technical Summary

Problems solved by technology

However, in the actual use of bone conduction earphones, due to special circumstances such as abnormal startup system of bone conduction earphones, user misoperation to adjust the bone conduction vibrator to the maximum volume, or abnormality of bone conduction vibrator during use, the vibration frequency of bone conduction vibrator will be generated. Relatively large fluctuations, but for users wearing bone conduction earphones, the vibration frequency of the bone conduction vibrator increases, and the user will feel that the bone conduction vibrator is hitting the head hard, which reduces the user experience. Comfortable; in addition, in the case of normal bone conduction headphones playing normally, the vibration frequency of the bone conduction vibrator should not be too small, otherwise the user will not be able to perceive the audio received through the bone conduction vibrator
