Problems solved by technology

[0004] In the existing helmets with bone conduction oscillators on the inner surface, there are still the following defects: that is, the anti-interference ability is relatively weak, and the bone conduction oscillators are provided with predetermined positions of the helmets. When the user is in a relatively stable environment ( For example, when walking or riding), the sound transmission effect of the helmet is good, but when the user is in a relatively unstable environment (such as during motorcycle riding), the sound transmission effect of the helmet is relatively poor

[0056] Wind noise includes variable noise, such as variable noise generated by motion, the intensity of which is proportional to motion acceleration or speed, and inherent noise, such as the current environment is relatively noisy. The above technical solution is intended to suppress variable noise, but cannot suppress inherent noise. When the intensity of inherent noise exceeds the threshold state, its users may not be able to continue to realize sound transmission.

Abstract

The invention belongs to the technical field of communication equipment, and concretely relates to an information transmission device and method based on a mobile terminal. The device comprises: an acquisition unit, which obtains a current vibration frequency of the information transmission device after the information transmission device is started and forms an acquisition information output; an information reception unit, which receives an audio signal output by the mobile terminal; a control unit, which forms a control signal output according to the received acquisition information and the audio signal; and a bone conduction unit, which generates mechanical vibration matching the audio signal under the effect of the control signal. The acquisition unit acquires the acquisition information that matches variable noise, the control unit forms a compensation signal output that can inhibit the variable noise on the basis of the acquisition information, the audio signal and / or a feedback signal, and the compensation signal and the variable noise are opposite in phase and consistent in amplitude. A wind noise resistance capability of the information transmission device is provided through the compensation signal, and an anti-interference capability of the information transmission device is improved.

Description

technical field [0001] The invention belongs to the technical field of communication equipment, and in particular relates to an information transmission device and a transmission method based on a mobile terminal. Background technique [0002] There are two ways for the human body to obtain sound. One way of sound transmission is air conduction, that is, the audio signal (sound wave) vibrates from the inner and outer lymph fluid of the inner ear, the cochlea senses the vibration and recognizes the sound process, and then the auditory nerve generates nerve impulses. Presented to the auditory center, after a comprehensive analysis by the cerebral cortex, the sound is finally heard. Specifically, the air conduction path is sound wave-auricle-external auditory canal-tympanic membrane-malleus-incus-stapes-vestibular window-external and endolymphatic-spiral organ-auditory nerve-auditory center; another sound transmission method is bone conduction In this way, the audio signal (ac...
