Problems solved by technology
However, due to differences in the tightness, angle, and strength of electronic equipment worn by different users, or even the same user, the optimal frequency division point of the bone conduction sensor will also change accordingly. Therefore, in related technologies, a fixed frequency division point is used to control electronic equipment The equipment solution has the disadvantage of poor universality, which reduces the signal quality of the audio signal collected by the electronic equipment

Embodiment Construction
[0036] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0037] In the bone conduction device, due to the hardware defect of the bone conduction sensor itself, the audio signal collected by the bone conduction sensor will have serious high-frequency attenuation. This results in incomplete audio signals collected by the bone conduction audio collection device. In related technologies, in order to solve the problem of incomplete audio signals collected by bone conduction audio collection equipment, a microphone and a bone conduction sensor are generally installed in the electronic device at the same time, and a fixed frequency division point is set to collect the frequency value through the microphone. For high-frequency audio higher than the fixed frequency crossover point, the bone conduction sensor collects low-frequency audio whose frequency value is lower than the freque...

The invention discloses an audio signal processing method. The method comprises the following steps: acquiring a first audio signal received by a bone conduction sensor and a second audio signal received by a microphone; determining a frequency division value according to the first audio signal and the second audio signal; and processing the first audio signal and the second audio signal accordingto the frequency division value to obtain an audio output signal of the electronic equipment. The invention further discloses the electronic equipment and a computer readable storage medium, and theeffect of improving the quality of the audio signals collected by the electronic equipment is achieved.
Description
technical field [0001] The invention relates to the technical field of audio collection, in particular to a processing method for audio signals, electronic equipment and a computer-readable storage medium. Background technique [0002] Bone conduction is a sound conduction method, which converts sound into mechanical vibrations of different frequencies, and transmits sound waves through the human skull, bone labyrinth, inner ear lymph fluid, spiral organ, and auditory center. Compared with the classic sound conduction method of generating sound waves through the diaphragm, bone conduction saves many steps of sound wave transmission, and can achieve clear sound reproduction in a noisy environment, and the sound waves will not affect others due to diffusion in the air . Due to the above-mentioned advantages of bone conduction, there have been devices that collect user voice signals based on bone conduction. [0003] However, in the bone conduction device, due to the hardware...
