Problems solved by technology

The current bone conduction earphones mainly use a single bone conduction vibrator, which converts the electrical signal carrying the sound into mechanical vibration and then transmits it to the bone labyrinth through the skull. Distortion, which is the main reason for the poor sound quality and poor user experience of current bone conduction headphones

Abstract

The invention discloses a tone quality improvement method and a bone conduction earphone. The bone conduction earphone comprises at least one bone conduction vibrator and a signal processing unit; each bone conduction vibrator is arranged at a corresponding position point on the skull; and different signal paths are formed between the bone conduction vibrators and the signal processing unit. The method comprises the following steps: after being received, an audio signal is responded through a first frequency response function corresponding to each signal path to obtain a corresponding responsesignal; and the response signals corresponding to all the signal paths are sent to the corresponding bone conduction vibrators respectively, so that the response signals are transmitted to the cochlea after being responded through second frequency response functions corresponding to conduction paths between the position points corresponding to the bone conduction vibrators and the cochlea. According to the technical scheme, the tone quality of the bone conduction earphone can be improved, the sound recovery degree is higher, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of bone conduction earphones, in particular to a method for improving sound quality and bone conduction earphones. Background technique [0002] Most traditional earphones use air conduction to achieve sound transmission, and the sound passes through the external auditory canal-tympanic membrane-hammerbone-incus-stapes-vestibular window-outer and inner shower-spiral organ-auditory nerve-auditory center. In the above-mentioned conduction process, the conduction link is complex, and once one of the links is obstructed or the function declines, it will seriously affect our hearing. [0003] When the performance of the human eardrum declines, the sound will be severely lost or even completely unable to stimulate the auditory nerve of the inner ear through air conduction. At this time, bone conduction can solve the above problems. [0004] The way of bone conduction of sound is directly through the skull-bone la...
