Description

Technical Field

[0001] This application relates to the field of sound wave generation technology, and more specifically, to a sound wave generation system. Background Technology

[0002] Sound wave generation systems are based on the principle of sound wave generation, which states that when an object vibrates, it propagates and vibrates in the surrounding medium (such as air or water), forming sound waves. Sound wave generation systems typically use various sound sources to generate sound waves, such as loudspeakers and ultrasonic transducers.

[0003] Among them, loudspeakers generate sound by converting electrical signals into sound signals, and ultrasonic transducers generate sound by converting electrical power into mechanical power. Both of these sound wave generation systems require stable operating frequencies and matching circuit parameters to work efficiently. However, due to the inherent instability of electrical signals, the stability of these sound wave generation systems is poor, and the sound intensity of these sound wave generation systems is low.

[0004] In conclusion, improving the stability of sound wave generation systems and increasing the intensity of sound wave generation are problems that urgently need to be solved by those skilled in the art. Utility Model Content

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0030] like Figures 1-4 As shown, the sound wave generating system provided in this application embodiment includes an air compressor 1, a whistle generating component 2, and a sound wave reflecting component 3. The air compressor 1 is used to compress air and provide a high-speed airflow. The high-speed airflow discharged from the air compressor 1 passes through the whistle generating component 2 to form a sound wave. The sound wave is reflected by the sound wave reflecting component 3, which increases the intensity of the sound wave.

[0031] The whistle generating assembly 2 includes an inlet pipe 21, an eddy current generating section 22, a resonant cavity 23, and a diffuser pipe 24, such as Figure 2As shown, the inlet pipe 21, vortex generating part 22, resonant cavity 23, and diffuser pipe 24 are sequentially connected along the same axis. The exhaust port of the air compressor 1 is connected to the inlet end of the inlet pipe 21, so that the high-speed airflow discharged from the air compressor 1 enters the whistle sound generating assembly 2 through the inlet pipe 21, and forms a sound wave after passing through the vortex generating part 22 and the resonant cavity 23 in sequence. In this embodiment, the airflow forms a sound wave through the whistle sound generating assembly 2. Each part of the whistle sound generating assembly 2 is only a mechanical structure, so that the sound wave formation process does not require an additional matching circuit, which can form a more stable sound wave and improve the stability of the sound wave generation system.

[0032] To increase the intensity of sound waves, such as Figure 2 As shown, the resonant cavity 23 is connected to the diffuser tube 24, which diffuses the sound waves generated by the resonant cavity 23, thereby increasing the intensity of the sound waves.

[0033] It should be noted that the whistle sound-producing component 2 also includes a housing 20, such as Figure 2 As shown, the inlet pipe 21, the eddy current generating part 22, the resonant cavity 23, and the diffuser pipe 24 are all located inside the housing 20. The housing 20 provides protection for the inlet pipe 21, the eddy current generating part 22, the resonant cavity 23, and the diffuser pipe 24, further ensuring the stability of the sound wave formation process.

[0034] To further enhance the sound wave intensity, the sound wave generating system provided in this embodiment of the application includes a sound wave reflecting component 3, and the outlet end of the diffuser tube 24 in the whistle generating component 2 corresponds to the sound wave reflecting component 3. For example, as shown... Figure 1 As shown, the whistle sound-generating component 2 is located above the sound wave reflecting component 3. The outlet end of the whistle sound-generating component 2 corresponds to the reflector plate 31 of the sound wave reflecting component 3. The reflector plate 31 reflects the sound wave generated by the whistle sound-generating component 2, further improving the intensity of the sound wave.

[0035] In practice, air compressor 1 is connected to whistle generator 2 via air supply pipe 10, such as... Figure 1 As shown, the air supply pipe 10 connects the whistle generating assembly 2 and the air compressor 1. Specifically, the air supply pipe 10 connects the inlet end of the inlet pipe 21 and the exhaust port of the air compressor 1. The air supply pipe 10 transmits the airflow discharged from the air compressor 1, ensuring the stability of the airflow transmission.

[0036] Because the airflow needs to reach a resonant frequency to resonate and form sound waves, the airflow discharged from air compressor 1 needs to be accelerated. For example... Figure 3As shown, the inlet pipe 21 includes a large-diameter section 210 and a small-diameter section 212. The inlet end of the large-diameter section 210 is connected to the exhaust port of the air compressor 1, and the outlet end of the small-diameter section 212 is connected to the vortex generating part, so that the airflow enters through the large-diameter section 210 and exits through the small-diameter section 212. The diameter of the large-diameter section 210 is larger than the diameter of the small-diameter section 212. In this way, the cross-sectional area through which the airflow passes from the large-diameter section 210 to the small-diameter section 212 is reduced. When the flow rate of the airflow through the inlet pipe 21 is a fixed value, the velocity of the airflow is increased, thus accelerating the airflow through the inlet pipe 21.

[0037] Because there is a certain difference in cross-sectional area between the large-diameter section 210 and the small-diameter section 212, in order to reduce the impact of airflow on the small-diameter section 212, the inlet pipe 21 includes a tapered end 211, such as... Figure 3 As shown, the tapering section 211 connects the outlet end of the large diameter section 210 and the inlet end of the small diameter section, and the tapering section 211 tapes from the large diameter section 210 to the small diameter section 212. In this way, the tapering section 211 provides a buffer and reduces the impact of the airflow on the small diameter section 212.

[0038] like Figure 3 As shown, the large-diameter section 210, the tapering section 211, and the small-diameter section 212 are distributed sequentially along the same axis, so that the speed of the airflow can gradually increase as it passes through the large-diameter section 210, the tapering section 211, and the small-diameter section 212, thus ensuring the stability of the airflow during acceleration.

[0039] In order for the airflow to have an angle with the axis of the resonant cavity 23 when it enters the resonant cavity 23, such as Figure 2 As shown, a vortex generating unit 22 is connected to the outlet end of the inlet pipe 21 to generate vortices. Specifically, the vortex generating unit 22 includes a vortex cavity 220, the inlet end of which is connected to the outlet end of the small-diameter section 212, so that the high-speed airflow generated by the inlet pipe 21 is discharged into the vortex cavity 220 and forms vortices through the vortex cavity 220. The outlet end of the vortex cavity 220 is connected to a resonant cavity 23, so that the vortex is discharged into the resonant cavity 23 and resonates within the resonant cavity 23 to form sound waves.

[0040] In order to enable the high-speed airflow to form vortices within the vortex cavity 220, such as Figure 4 As shown, the inner wall of the vortex cavity 220 is provided with guide vanes 221. The guide vanes 221 are distributed along the axial direction of the vortex cavity 220, so that the airflow rotates in the vortex cavity 220 under the guidance of the guide vanes 221 and moves towards the outlet end of the vortex cavity 220, thereby forming a vortex.

[0041] In some embodiments, such as Figure 4As shown, multiple guide vanes 221 are provided on the inner wall of the vortex cavity 220. The multiple guide vanes 221 are distributed sequentially along the axial direction of the vortex cavity 220 and are distributed along the same helical line so that the airflow rotates under the guidance of the multiple guide vanes 221 after entering the vortex cavity 220. Furthermore, by adjusting the number of guide vanes 221 and the angle between the guide vanes 221 and the inner wall of the vortex cavity 220, the intensity of the formed vortex can be adjusted, thereby expanding the intensity range of the formed sound wave.

[0042] In some other embodiments, a guide vane 221 is provided on the inner wall of the vortex cavity 220. The guide vane 221 is integral and spiral-shaped, so that the airflow rotates under the guidance of the guide vane 221 after entering the vortex cavity 220, thereby improving the stability of vortex formation.

[0043] It should be noted that, due to the large impact force of high-speed airflow, the guide vane 221 is made of wear-resistant metal materials, such as titanium alloy, hard alloy, and high manganese steel, so that the guide vane 221 can withstand the impact of high-speed airflow, extend the service life of the guide vane 221, and further improve the stability of vortex formation.

[0044] like Figure 2 As shown, the outlet end of the eddy current generator 22 is connected to the resonant cavity 23 so that the eddy current generated by the eddy current generator 22 resonates in the resonant cavity 23 to form a sound wave. Specifically, the resonant cavity 23 includes a resonant cavity body, the inlet end of the resonant cavity body is connected to the outlet end of the eddy current cavity 220, and the interior of the resonant cavity body is provided with a reflective layer or reflective structure for reflecting the eddy current.

[0045] For example, the resonant cavity is provided with a smooth layer for reflecting eddy currents. After the high-speed eddy current enters the resonant cavity, it vibrates in the resonant cavity under the reflection of the smooth layer. When the high-speed eddy current vibrates in the resonant cavity to the resonant frequency, the eddy current forms a sound wave.

[0046] In some other embodiments, the resonant cavity is provided with a reflective structure for reflecting eddy currents, such as a mirror or reflector. After the eddy currents enter the resonant cavity, they vibrate and form sound waves under the action of the reflective structure. The reflective structure is detachably installed in the resonant cavity, and the intensity of the formed sound waves can be adjusted by replacing different reflective structures, thereby further expanding the intensity range of the formed sound waves.

[0047] In order to increase the frequency response range of eddy currents within the resonant cavity, such as Figure 2 As shown, the resonant cavity is cylindrical, which can increase the range of reflection angles of eddy currents within the resonant cavity and further increase the frequency response range of eddy currents within the resonant cavity.

[0048] In some other embodiments, the resonant cavity is spherical, which can further increase the range of angles at which eddies are reflected within the resonant cavity, thereby further increasing the frequency response range of the generated sound waves.

[0049] Of course, since the size and shape of the resonant cavity can affect the frequency of the sound wave, the resonant cavity can also be a square cylinder, a hemisphere, etc. in order to form sound waves of different frequencies. This application does not limit this.

[0050] To increase the intensity of sound waves, such as Figure 2 As shown, the outlet of the resonant cavity 23 is connected to the diffuser tube 24, which is used to diffuse the sound waves generated in the resonant cavity 23. The diffuser tube 24 is a gradually expanding tube, and the diffuser tube 24 gradually expands from the inlet end of the diffuser tube 24 to the outlet end of the diffuser tube 24. After the sound waves are generated in the resonant cavity 23, they are discharged from the inlet end of the diffuser tube 24 to the outlet end of the diffuser tube 24, which enhances the intensity of the sound wave.

[0051] To further increase the intensity of sound waves, such as Figure 1 As shown, after the sound wave is emitted from the diffuser 24, it is reflected by the sound wave reflecting component 3. The sound wave reflecting component 3 includes a bracket 30, a reflector 31, and a sound wave sensor 32.

[0052] The reflector 31 is parabolic in shape, and the opening direction of the parabola corresponds to the outlet end of the diffuser 24. For example, Figure 1 As shown, the reflector 31 and the whistle-generating component 2 are arranged vertically, with the outlet end of the diffuser 24 pointing downwards and the opening direction of the parabola corresponding to the diffuser 24 pointing upwards. When a sound wave strikes the parabolic surface of the reflector 31, according to the principle of parabolic reflection, the sound wave will be reflected at the same angle as the incident sound wave and focused at the focal point of the parabola. In this way, by focusing the sound wave to a point or a small area, the density and intensity of the sound wave can be significantly increased.

[0053] In order to better support the parabolic reflector 31, such as Figure 1 As shown, the bracket 30 is roughly U-shaped, which facilitates the support of the reflector 31; a sound wave sensor 32 is provided on the bracket 30, which can detect the intensity of the sound wave, so that the intensity of the sound wave can be adjusted through the feedback of the sound wave sensor 32.

[0054] Specifically, the intensity of the sound wave is adjusted through the control system 4. The control system 4 includes a controller and a data processor that is communicatively connected to the controller. The data processor is communicatively connected to the sound wave sensor 32 and can convert the electrical signal of the sound wave detected by the sound wave sensor 32 into a digital signal. The controller is connected to the air compressor 1. After judging the digital signal processed by the data processor, it issues control commands to the air compressor 1 according to the actual situation, adjusting parameters such as the exhaust pressure, exhaust flow rate, exhaust speed, and operating frequency of the air compressor 1, thereby adjusting the intensity of the generated sound wave.

[0055] Specifically, adjusting the exhaust pressure of the air compressor can regulate the pressure of the output airflow. Higher exhaust pressure creates a stronger airflow impact, thus increasing the intensity of the sound waves. Exhaust flow rate refers to the volume of gas discharged by the air compressor per unit time. Increasing the exhaust flow rate allows more gas to be released into the environment quickly per unit time, thus increasing the intensity of the sound waves. Exhaust velocity refers to the speed at which the airflow exits the compressor. Increasing the exhaust velocity results in a stronger airflow impact and faster air molecule vibration, thus increasing the intensity of the sound waves. When using an air compressor with an adjustable operating frequency, the operating frequency can affect the repetition rate and intensity of the airflow pulses, thereby indirectly affecting the intensity of the sound waves.

[0056] In practice, the acoustic wave generation system provided in this application embodiment also includes a power supply component 5, which provides electrical energy to the control system 4, the air compressor 1, and the acoustic wave sensor 32. For example, the power supply component 5 includes a solar panel and an energy storage device connected to the solar panel via a cable, saving costs. The energy storage device, connected to the control system 4, the air compressor 1, and the acoustic wave sensor 32 via a cable, can provide a stable voltage, ensuring the stability of the acoustic wave generation system's operation.

[0057] Of course, power can also be supplied by other power supply components 5, such as generators, transformers and other power generation equipment. This application embodiment does not limit this.

[0058] When the sound wave generating system provided in this embodiment is working, firstly, the power supply component 5 connects to the control system 4, the air compressor 1, and the sound wave sensor 32 to provide power. The control system 4 connects to the air compressor 1 and the sound wave sensor 32 to prepare for detection and adjustment. After preparation, the air compressor 1 is started. The airflow discharged from the air compressor 1 is discharged to the whistle generating component 2 through the air supply pipe 10. The airflow passes through the inlet pipe 21, the vortex generating part 22, and the resonant cavity 23 in the whistle generating component 2 in sequence to form a sound wave. The sound wave is diffused through the diffuser pipe 24 and then emitted onto the reflector plate 31. After being reflected by the reflector plate 31, the intensity and density of the sound wave are further enhanced. In addition, the support 30 is equipped with a sound wave sensor 32. The sound wave sensor 32 feeds back the intensity of the detected sound wave to the control system 4. After data processing, the control system 4 adjusts the parameters such as the exhaust pressure, exhaust flow rate, exhaust speed, and operating frequency of the air compressor 1 according to the data fed back by the sound wave sensor 32, so that the intensity of the generated sound wave can be adjusted and the response range of the sound wave frequency is increased. The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
