Conventionally, in order to make sound insulation or sound insulation, a wall made of a mechanical structure such as plywood and iron plate is installed to block noise. Structures such as plywood and steel plates with a certain thickness were used to obtain sufficient sound insulation effects, and sound absorbing materials for absorbing noise were used to increase the sound insulation effect.

The present invention is used in offices, auction houses, banks, restaurants, conference rooms, meeting rooms, noisy workshops, factories, etc., which are used by many people without using individual partitions made of plywood, plastic, or steel mechanical structures, which have been conventionally used. An object of the present invention is to propose a sound insulation or sound insulation device that effectively controls the generated ambient noise.

In addition, the present invention has an object to reduce the noise by the ultrasonic masking method using the ultrasonic waves as described above.

In addition, an object of the present invention is to provide an odor diffusion preventing device, smoke diffusion preventing device, dust diffusion preventing device, air flow blocking device, heat loss blocking device and method using ultrasonic waves.

To this end, the present invention is to propose a device for preventing the progress of the noise by forming a high-power ultrasonic barrier using a high-power ultrasonic wave generating means.

First, we will define the term.

In the present invention, "high power" is a relative meaning, when the noise source is a human, it refers to sound waves having a larger energy (or power in the case of a uniform power) than the sound pressure of a normal human voice, and the noise source is not a human voice. In the case of sound from a car, sound waves with a large amplitude compared to the sound pressure generated from the noise source mean energy (or equivalent power). Therefore, high power does not mean any more power than expressed in absolute numbers.

"Ultrasound" is a sound wave of high frequency that is inaudible to the human ear. The audible sound frequency that humans can hear is between 20 and 20,000 Hz, and sound waves with frequencies above 20,000 Hz are called ultrasonic waves. Ultrasound here means sound waves that humans cannot hear and does not set absolute numbers. Here we define sound waves that are too high for humans to hear. Of course, the range of sound waves that cannot be heard can vary from person to person. In addition, the frequency used here includes frequencies above l00 MHz, for example, meaning that the frequency includes all frequencies in which the general public is too high to hear.

Thus, for example, the case of a "high power ultrasonic wave" is a noise source.

It is about 50 dB based on the voice of a normal person, but sound waves with about 70 dB or more energy with a noise intensity of 100 times higher than the voice that is a noise source can play the role of "high power ultrasound". It does not have to be 70dB or more, and the ultrasonic energy is greater than this, the sound insulation and sound insulation effect is greater. In addition, the noise level of the high-powered ultrasonic waves required for the ambient noise to block them is higher.

According to the present invention, even without using a partition or soundproofing device, which is a conventional mechanical structure, soundproofing or soundproofing can be performed for each group in the same space. , Chat is possible.

The present invention proposes an apparatus for reflecting sound waves using one or more high power ultrasonic wave generating means for generating high power ultrasonic waves instead of the mechanical structure which has been used so far to reflect sound waves. For this purpose, an ultrasonic generating speaker is required.

Although it is a well-known fact, in order to explain this, first, the definition, the nature and the method of generating the ultrasonic wave will be described.

Ultrasound is a sound wave with a high frequency that cannot be heard by the human ear. The audible sound frequency that humans can hear is between 20 □ 20,000 Hz, and sound waves with frequencies above 20,000 Hz are called ultrasonic waves.

Ultrasonic waves have a high frequency and therefore short wavelengths, and exhibit a property that cannot be seen in normal sounds, for example, due to the fact that a very strong vibration is obtained.

Ultrasound is a longitudinal wave like general sound waves, and there are propagation, reflection and reflection phenomena. In the case of ultrasonic waves, the sound waves are more linear than in the case of general sound waves. In addition, the higher the frequency, the better the linearity of sound waves including ultrasonic waves. In the present invention, a moving coil type speaker may be used, but a piezoelectric element is used, and when a flat speaker is used, ultrasonic waves may be flattened to move straight away.

To this end, the present invention proposes an acoustic partition system for sound insulation or sound insulation using high power ultrasonic wave generation means for generating high power ultrasonic waves in place of a structure such as a partition or a wall of an office.

Ultrasound used in the present invention means all frequencies higher than the audio frequency range. For efficient sound reflection and absorption, the amplitude or frequency needs to be 10 times or 100 times higher than that of sound waves, and the higher the frequency, the better the straightness. The reason for using ultrasonic waves is to keep high power air barriers invisible to human ears. This is because it can be formed. High power means that the amplitude is large as mentioned above. Ultrasonic waves with high amplitude and high frequency, that is, high-power ultrasonic waves, proceed by shaking the air molecules severely (ie, longitudinal waves) in the direction of movement, and the speed of the air molecules is caused by the speed of air molecules due to the sound waves generated from the noise source. It is much larger than the velocity of air molecules due to sound waves generated from the noise source, which blocks the direction of sound waves caused by the noise source. For example, as a noise source, a human voice can be a noise source, but in some cases, a car sound, a piano sound, etc. can also be a noise source.

Therefore, the intensity of the sound wave generated in the high-power ultrasonic waves can also vary in size depending on the noise source.

BRIEF DESCRIPTION OF THE DRAWINGS Explanatory drawing which compares the waveform of a sound wave and a high power ultrasonic wave.

The high power ultrasound 110 is much larger than the sound wave 120 in terms of amplitude, and the frequency is much higher.

The amplitude of the high power ultrasound is much larger than the sound wave to prevent the progress of the sound wave, because the frequency of the ultrasonic region can not hear the ordinary person.

However, it does not fit the scale, but is drawn simply for explanation.

2 is a block diagram showing the internal configuration of the high power ultrasonic wave generating means.

When the ultrasonic electric signal generated by the ultrasonic electric signal generating means 210 passes through the amplifier 210, the power is amplified, and the amplified high frequency electric signal generates high power ultrasonic waves by the speaker 230.

3 is a perspective view of the high power ultrasonic wave generating means.

As described above, the high power ultrasonic wave generating means is composed of the ultrasonic electric signal generating means 210, the amplifier 210, and the speaker 230. As shown in the figure, the flat speaker 310 fixes the flat speaker 310. At the same time it is coupled with the speaker fixing frame 320, which is equipped with an ultrasonic electric signal generating means and an amplifier.

Piezoelectric speakers with metal plating on both sides of the piezoelectric material are efficient for the generation of ultra high frequency ultrasonic waves, but speakers using moving coils can also be used in the very high ultrasonic range.

5 is an explanatory diagram showing a phenomenon in which low power sound waves encounter a high power ultrasonic barrier generated by the present invention.

The high power ultrasonic wave 520 generated by the high power ultrasonic wave generating means 550 interferes with the sound wave 540 generated by the sound wave generating means 530, and blocks the progress of the sound wave 540. In other words, it blocks the transmission of sound waves. The present invention uses this principle. The high-power ultrasonic wave 520 generated by the high-power ultrasonic wave generating means 550 has a much larger amplitude, a higher linearity, and a higher frequency than the sound wave 540, so that the sound pressure per unit area with respect to the advancing direction of the high-power ultrasonic wave 520 is high. Because 540 is much larger than the case. In the case of the sound wave 540, although the energy of the voice is low, sound is radiated from the sound source so that the sound pressure is low in the region facing the high power ultrasonic wave 520. If the sound pressure is large, the power of the high power ultrasonic wave 620 may be further increased.
