Description

Method and device for detecting and eliminating snoring noise by using mobile phone

technical field

The present invention belongs to the field of noise elimination, and in particular refers to a method and device for detecting and eliminating snoring noise by using a mobile phone that can effectively detect snoring and eliminate noise with a very remarkable effect. .

Background technique

Snoring (snoring) is a common phenomenon in society, and there are many reasons for its occurrence, such as age, fatigue, obesity, etc., which not only affects sleep quality, but even endangers health.

What's more, snoring is not only a personal sleep disorder problem, but also an obstacle to social and family life. Especially in the dead of night, any small sound may affect the sleep state of the people around, not to mention the persistent snoring sound? It even made the person next to the pillow unbearable, so they slept in separate rooms, which affected the relationship between husband and wife.

For this reason, those who have snoring troubles are not only personal problems, but may also be problems of the whole family, or even neighbors and work teams. They should be taken seriously and treated.

However, there are many reasons for snoring, and its diagnosis and medical treatment are mostly lengthy processes, which cannot produce real-time effects. Also, some people may just be fatigued temporarily, and snoring occurs occasionally and cannot be effectively predicted.

Therefore, being troubled by the snoring of others still happens every day. At this time, besides being patient, I can only choose to stay away.

For this reason, the inventor of this case feels that although the snoring matter is small, it has to be paid attention to, so it is actively researched, hoping to obtain a solution.

In the past solutions, in order to alleviate the snoring phenomenon, the snorer must be conscious and seek a solution before going to bed to reduce the impact on others. If the snorer is not aware of it, or the solution is ineffective, the person disturbed by the snoring has no effective solution and can only let the snoring continue.

Therefore, the main idea of the inventor is to change passive to active, so that the process of alleviating snoring can be carried out automatically without being restricted by the snorer.

Since snoring is also a kind of noise, it can naturally be solved by noise cancellation. Common noise cancellation technologies include passive noise control (Passive Noise Control, PNC) and active noise control (Active Noise Control, ANC). The passive method is to use isolation methods or sound-absorbing materials to block the external influence of noise. This method needs to install insulating materials at the source of the noise, which is obviously not suitable for the human body; while the principle of the active method is to detect and analyze noise. components, and then drive the loudspeaker to generate sound waves with the opposite phase to the noise but the same amplitude, so that the sum of the sound waves in the sound field is zero, so as to achieve the effect of canceling the noise. This method has little change in the noise source and the surrounding environment, so it is feasible for this case technology.

Then, in order to play the function of eliminating snoring sound in real time, we need a device that can receive sound, analyze it, and generate anti-phase sound wave output at any time. The noise elimination equipment seen so far is mostly large-scale and professional machines because they are aimed at unspecified noise sources, and use a large amount of computing power to conduct noise analysis for noise elimination. Fortunately, snoring belongs to a specific noise source, and its acquisition and analysis methods are relatively easy. In addition to the rapid development of science and technology, the current common mobile phone devices have the relevant capabilities. As long as they are used properly, they can play the functions required by the present invention .

After long-term research and development and implementation by the inventor, the method and device for detecting and eliminating snoring noise by using a mobile phone were finally completed.
