Abstract

The invention discloses an output processing method of audio signals of wearable equipment and the wearable equipment. The method includes: obtaining to-be-output audio signals of the wearable equipment; obtaining a phase adjusting parameter corresponding to each bone conduction oscillator of a bone conduction oscillator matrix of the wearable equipment; performing phase adjustment on the to-be-output audio signals based on the phase adjusting parameter corresponding to each bone conduction oscillator to obtain a target audio signal corresponding to each bone conduction oscillator; and outputting the target audio signal to the corresponding bone conduction oscillator, controlling all the bone conduction oscillators of the bone conduction oscillator matrix, converting the corresponding target audio signals to vibration signals, and transmitting the vibration signals through skin and bone media so that the vibration signals of all the bone conduction oscillators of the bone conduction oscillator matrix are superposed with the same phase at a certain position in a transmission process through the skin and the bone media. According to the method and the wearable equipment, the attenuation of the audio signals in the transmission process is reduced, the tone quality is guaranteed, the sound leakage is prevented, and the user privacy is protected.

Description

technical field [0001] The invention relates to the technical field of wearable devices, in particular to a method for outputting audio signals of a wearable device and the wearable device. Background technique [0002] Wearable devices (such as wrist-worn smart phones, smart watches, smart bracelets, etc.) are becoming more and more popular and accepted by people. However, wearable devices usually use the external sound mode during the process of calling and playing music. When the external sound is released, it may interfere with others, and may also cause the user's privacy to be eavesdropped by the surrounding people, which is not conducive to protecting user privacy. Safety reduces the user experience. Contents of the invention [0003] The embodiment of the present invention discloses an output processing method of an audio signal of a wearable device and the wearable device, which are used to reduce the attenuation of the audio signal during transmission, ensure so...
