Ultra-low audio sound wave generating device for suction filtering noise

This creation is about a sequence effector (computing system), especially an ultra-low frequency sound wave generating device in the same frequency band as the brain wave.

Resonant music with the same frequency of brain waves has been widely known in recent years, and many large medical institutions have recognized and introduced it as a medical auxiliary user to achieve stable emotions, develop potential, and help sleep. According to the existing method, the user can achieve the effect by listening to music that can emit a special frequency. However, since the sound wave that can resonate with the brain wave belongs to the ultra-low frequency range, it is not a frequency band that can be directly generated by a general audio equipment.

The applicant has used the two sounds to simultaneously sound the sound waves in the ultra-low frequency range. When the sounds of the two sounds are mixed, they can be physically arranged in addition to the respective frequencies, and can also be arranged according to the instrument. Produce ultra-low frequency sound waves with a frequency difference between each other (application No. 105204961, Taiwan new patent). Such ultra-low frequency sound waves are physically difficult to hear even in the human ear, but physically still have audio.

However, the applicant has found that although the ultra-low frequency sound wave can be generated, the original two kinds of audio will generate their respective noises after the audio is mixed, and the noise audio system is higher than the audio of the aforementioned ultra-low frequency sound wave, so when the speaker plays out At the time of the ultra-low frequency sound wave, it may be accompanied by a high-pitched noise, which is not perfect.

In view of the problems of the prior art, the creator of the present invention has created an ultra-low audio sound wave generating device for a filter noise according to the spirit of research and development, including a first general waveform generator and a second general waveform. a generator, the two general-purpose waveform generators are connected to a first signal integration unit to obtain an ultra-low frequency sound wave by using an audio phase difference, the first signal integration unit is connected to an effector, and the effect is passed through a second The signal integration unit is connected with a universal signal amplifier, and the universal signal amplifier is connected with a speaker, and the outer edge of the speaker is covered with a suction filter audio layer, and the suction filter audio layer can filter the external noise, and the external noise audio The audio is greater than the ultra-low frequency sound wave, and the suction filter audio layer maintains a distance from the outer edge of the speaker.

The first picture is a schematic diagram of the relationship between the various components of the creation.

The following is a description of the structure, features and examples of the creation, which will enable your reviewers to have a better understanding of the creation.

Referring to the first figure, the present invention relates to an ultra-low audio sound wave generating device for suction noise, comprising a first general waveform generator (1) and a second universal waveform generator (2), the two The universal waveform generators (1) and (2) are connected with a first signal integration unit (3) to obtain an ultra-low frequency sound wave by using the audio phase difference, and the first signal integration unit (3) and an effect device (4) Connected, and the effector (4) is connected to a universal signal amplifier (6) via a second signal integration unit (5), and the universal signal amplifier (6) is connected with a speaker (7), the speaker (7) The outer edge is covered with a suction filter audio layer (8), and the suction filter audio layer (8) is capable of filtering the external noise, and the audio of the external noise is greater than the audio of the ultra-low frequency sound wave, and the suction filter audio layer (8) ) maintain a distance from the outer edge of the speaker (7).

The first general waveform generator (1) is mainly used to generate a sound waveform having a frequency value of P1. The second universal waveform generator (2) is mainly used to generate a sound waveform having a frequency value of P2. Use the first signal integration order The element (3) can be used to combine the audio from the first general waveform generator (1) and the second general waveform generator (2) to generate a "frequency difference" (P1-P2), This frequency difference is utilized to generate ultra-low frequency sound waves that conform to the range of frequencies that are normally possible.

The effect (4) can be used to calculate the integrated audio to transform its sound characteristics into audio, and the effect (4) can use, for example, a universal space effect to produce an effect such as a Reverb. The second signal integration unit (5) can be used to integrate the audio, and then the audio is amplified by the universal signal amplifier (6) and output to the speaker (7).

According to the above configuration, as long as the audio content to be played and the ultra-low frequency sound wave to be generated are executed and integrated in steps and manners, ultra-low frequency sound waves which are widely used in the same frequency band as the brain wave can be manufactured. When the music file is blank, it can be regarded as “mute” mode. The user can set the ultra-low frequency sound wave band to the corresponding brain wave segment to be upgraded in any place, such as the Alpha wave band, Theta wave, etc., suitability. Great expansion.

In this method, the novel creation can be superimposed to generate multiple ultra-low frequency sound waves to increase its intensity without generating noise.

In addition, according to this method, the sound waves generated by the novel creation can be used in addition to indoors and outdoors, and since it is an acoustic sound that is audible to listen to, it can be applied to a moderate amplitude, and the user can use it in a general indoor place. The generated ultra-low frequency sound wave energy is not too large, even if it is switched to the "silent" mode, there is no doubt that it pollutes the environmental sound field, and it is a pure and harmless design.

The ultra-low frequency sound wave generating device that can be used to generate silence, mainly through the oscillator, the effect, the band rejection filter, and the signal integration unit to put the air frequency band in the music file into the hidden sound wave, so that the utility model can be widely applied. Ultra-low frequency sound waves in the same frequency band as the brain wave. It can generate ultra-low frequency sound waves in the way of general cognition as "silent", which is more convenient and popular than existing potential development machines and brain wave resonance instruments.

However, the higher portion of the audio generated by the first general waveform generator (1) and the second general waveform generator (2) may still be transmitted along with the frequency difference to generate ultra low frequency sound waves. Therefore, the outer edge of the speaker (7) is covered with a suction filter audio layer (8), and the suction filter audio layer (8) is capable of filtering out the external noise, and the audio of the external noise is greater than the audio of the ultra-low frequency sound wave, and the The suction filter audio layer (8) is spaced from the outer edge of the speaker (7) to prevent all sound waves from being coated or absorbed.

The frequency difference produces a higher ultra-low frequency sound wave penetration and can penetrate the speaker (7), and the first universal waveform generator (1) and a second universal waveform generator (2) respectively generate audio The higher part is adsorbed and filtered. In addition, a purer ultra-low frequency sound wave can be obtained.

In summary, the new creation is indeed in line with the industrial use, and was not found in the publication or public use before the application, nor is it known to the public, and has non-obvious knowledge, meets the requirements of patentability, and patents according to law. Application.

However, the above-mentioned findings are a preferred embodiment of the novel creation in the industry. The equal changes made by the scope of the patent application for this new creation are all within the scope of the claim.
