Description
Technical Field
The invention relates to the technical field of intelligent wearable equipment, in particular to a bone wheat receiving and processing device for a neck-worn voice interaction earphone.
Background
Along with the development of intelligent wearing equipment and the continuous improvement of people's standard of living, the use of various intelligent wearing equipment like intelligent wrist-watch is more and more popularized, and intelligent wearing equipment has become the indispensable communication instrument in people's life.
A person can hear sound because vibrations in the air transmit vibrations through the external ear canal to the eardrum, and the vibrations formed by the eardrum drive the auditory nerve of the person. When the middle and outer ear of a person is damaged or the ear canal is plugged by a hand, sound can transmit sound vibration through the skin and bones of the person to drive the auditory nerve of the person.
Bone conduction is a sound conduction mode, and sound waves are transmitted through skull, temporal bone, bone labyrinth, inner ear lymph fluid transmission, cochlea, auditory nerve and auditory center of a human, which is a bone conduction technology. Bone conduction is the vibration of the skull or temporal bone, which is transmitted directly into the inner ear without passing through the outer and middle ear. Compared with the traditional air conduction mode of generating sound waves through a loudspeaker diaphragm, the bone conduction mode omits a plurality of sound wave transmission steps, can realize clear sound restoration in noisy pipe diameters, and does not influence her people due to the fact that the sound waves are diffused in the air.
However, bone conduction techniques also have several disadvantages: (1) the amount of bone conduction sound is related to the location of contact with the bone and also to the characteristics of the human tissue. For example: the differences of the users such as age, gender and weight can cause different users to have different experiences when using the same bone conduction headset, and the different experiences are often performance deterioration. (2) When a user receives or sends a call by using a bone conduction technology, the bone conduction device is required to be tightly attached to a bone, a sinking wave is directly transmitted to an auditory nerve through the bone, the wearing mode determines that the bone conduction device is required to be highly pressed on the bone to be transmitted, the quality of audio transmission is affected if the bone conduction device is loosened, and the wearing mode of the highly pressed bone enables the comfort and the skin health of the user to be affected to different degrees in the using process. (3) Bone and human tissue produce frequency selective amplitude attenuation and delay for the shendong signal, and high fidelity or broadband audio signals are difficult to conduct to the auditory nerve through the bone, so most users based on the prior art complain about poor "tone quality" and "timbre" of bone conduction headphones. (4) Bone conduction sound leakage. Most of the existing bone conduction technologies cannot really solve the problem of bone conduction sound leakage because the existing technologies compensate the frequency-dependent real-world situation of human bone and tissue attenuation vibration signals by large volume and large vibration signals, which is equivalent to Yinzi 40489, and the user complains that the sound leakage is serious, or because more power is needed, the volume weight of the bone conduction sound is greatly increased, and the whole device is too heavy. (5) The bone conduction headset is an open binaural system, and when a user is in a noisy environment, the user cannot hear sound transmitted from the headset at all due to the openness of the bone conduction headset.
Patent application No. 102084668A discloses a method and system for processing signals, the system comprising: (a) a processor arranged to process a first input signal detected by the first microphone at a detection time, a second input signal detected by the second microphone at the detection time, and a third input signal detected by the first microphone at the detection time to produce a corrected signal responsive to the first, second and third input signals; and (b) a communication interface configured to provide the corrected signal to an external system. The method carries out noise reduction processing on the sound through a convolution function, and obtains a more accurate sound signal. However, since several sounds are mixed, some sounds are easily mistakenly determined as correct sounds and recorded in the track, and thus the output sound is not completely accurate and clear.
The patent application with the application number of 105721973a discloses a bone conduction headset and an audio processing method thereof, wherein the bone conduction headset comprises a human skeleton and tissue model modeling module, a mathematical pre-corrector, a delay estimation unit, a digital-to-analog converter, an analog-to-digital converter, a first low-pass filter, a second low-pass filter, an audio amplifier, an audio driving amplifier, at least one first microphone and at least one bone conduction oscillator; monitoring attenuation effect information of human bones and tissues of different users in real time, generating a compensation transfer function based on the attenuation effect information, and conducting the input audio signal in the bones and the human tissues after carrying out digital pre-correction on the input audio signal through the compensation transfer function. The method is mainly used for solving the problem of attenuation of audio signals, and correct audio data cannot be distinguished from noise.
