[0002] Sound waves are a kind of mechanical waves, and their energy can be transmitted through a medium. When sound waves act on sound-absorbing and sound-insulating materials, they will cause the materials to vibrate. Therefore, sound-absorbing and sound-insulating materials are often used in the prior art for indoor sound insulation.

[0003] The form of power generation that generates electric current through the movement of electric charges is gradually emerging and moving to all areas of life as much as possible. At the same time, with the increasing awareness of environmental protection, the demand for sound insulation and noise reduction in living and working environments is gradually increasing. When sound-absorbing and sound-insulating materials are used for sound absorption, sound insulation and noise reduction in the existing technology, the sound wave energy is consumed by being converted into the vibration of the material. However, from the perspective of material vibration and charge transfer power generation, it provides the possibility for the utilization of sound energy.

[0009] Furthermore, the mounting frame group also includes a ramp frame, and slots are provided on both sides of the middle frame.

[0016] Moreover, the present invention installs the power generation device at the required position and allows the power generation device to adapt to the installation state by setting up a mounting frame group to cooperate with the basic frame installed on the building. The former is specifically achieved by snap-fitting the main outer ring frame with the basic frame, and the latter is specifically achieved by setting an inner limit frame with a limit pin between the first electrode plate and the second electrode plate to limit the position of the movable parts, thereby avoiding uneven distribution of the movable parts such as local accumulation or excessive dispersion after multiple vibrations, and avoiding sinking and accumulation of the power generation device when it is laid vertically, and ensuring that the movable parts can be in contact with the first electrode plate in advance.

DETAILED DESCRIPTION

[0026] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] Examples, such as Figure 1-Figure 8 As shown: The present invention provides a power generation device based on acoustic energy resonance, the structure of the power generation device includes a hole plate 1, a resonance chamber 2 and a power generation component 3 connected in sequence, the hole plate 1 is densely provided with a plurality of through holes, the through holes include a neck hole 1a and a cavity hole 1b with a diameter larger than the neck hole 1a, the neck hole 1a and the cavity hole 1b are arranged in sequence from the outside to the inside of the hole plate 1, one end of the resonance chamber 2 is connected and installed on the inside of the hole plate 1, and the resonance chamber 2 has a cavity, thereby forming a Holm Hertz resonance cavity at the cavity hole 1b of the hole plate 1 and the cavity of the resonance chamber 2, the hole plate 1 and the resonance chamber 2 are used to receive sound waves and generate vibrations, so that the resonance chamber 2 generates vibrations, thereby driving the power generation component 3 to vibrate, so that the power generation component 3 converts the mechanical energy of the vibration into electrical energy, and the hole plate 1 and the resonance chamber 2 can be made of common sound-absorbing materials, such as polyester fiber, rubber, etc. To this end, the power generation component 3 includes a first electrode plate 31 and a second electrode plate 32. The other end of the resonance chamber 2 is directly connected to the first electrode plate 31, so that the resonance chamber 2 not only generates vibration for the power generation component 3, but also uses the first electrode plate 31 to form a cavity surface of the resonance chamber 2 cavity, so that the sound wave vibration will first drive the first electrode plate 31 to vibrate. A middle frame 34 is provided between the first electrode plate 31 and the second electrode plate 32. The first electrode plate 31, the second electrode plate 32 and the middle frame 34 cooperate to surround and form an inner cavity. In addition, a plurality of movable parts 33 are provided in the inner cavity. The movable parts 33 are spherical. The spacing between the first electrode plate 31 and the second electrode plate 32 is greater than the diameter of the movable part 33. The vibration of the inner cavity formed by the cooperation of the first electrode plate 31, the second electrode plate 32 and the middle frame 34 and the vibration generated by the first electrode plate 31 directly receiving the sound wave drive the spherical movable part 33 to vibrate in the inner cavity. The first electrode plate 31 and the second electrode plate 32 are repeatedly contacted, and the first electrode plate 31 and the second electrode plate 32 have the same electronegativity and are different from the electronegativity of the movable part 33, that is, the relative ability to gain and lose electrons is different, and the electronegativity of the first electrode plate 31 and the second electrode plate 32 is less than the electronegativity of the movable part 33. In this embodiment, the movable part 33 is made of polytetrafluoroethylene, and the first electrode plate 31 and the second electrode plate 32 are made of copper. When the first electrode plate 31 and the second electrode plate 32 are in contact with the movable part 33, the first electrode plate 31 and the second electrode plate 32 are more likely to lose electrons and thus carry a positive charge, while the movable part 33 is more likely to gain electrons and thus carry a negative charge. The first electrode plate 31 and the second electrode plate 32 are connected through an external circuit, and the power generation component 3 receives vibrations from the orifice plate 1 and the resonance chamber 2 to make the movable part 33 in the inner cavity move between the first electrode plate 31 and the second electrode plate 32.

[0028] Specifically, the movable part 33 in the power generation component 3 is in contact with the first electrode plate 31 in a stationary state, and the polytetrafluoroethylene material has a stronger attraction to electrons, causing the electrons to be transferred from the surface of the copper electrode plate to the polytetrafluoroethylene movable part 33. At this time, the copper first electrode plate 31 and the second electrode plate 32 and the surface of the polytetrafluoroethylene movable part 33 carry equal amounts of positive charge and friction negative charge respectively; when the polytetrafluoroethylene movable part 33 is vibrated, in the front part of a vibration fluctuation, the distance between the movable part 33 and the first electrode plate 31 increases, and the interaction between the negative charge on the surface of the movable part 33 and the first electrode plate 31 is weakened, and an electric potential difference is generated between the first electrode plate 31 and the second electrode plate 32, thereby generating a potential difference from the first electrode plate 31 to the second electrode plate 32. The instantaneous current of the electrode plate 32, the positive charge is transferred from the first electrode plate 32 to the second electrode plate 31 through the external circuit, and the charge transfer is completed when the polytetrafluoroethylene movable part 33 contacts the second electrode plate 32; on the contrary, in the latter part of a vibration fluctuation, when the polytetrafluoroethylene movable part 33 leaves the second electrode plate 32 and contacts the first electrode plate 31, the reverse movement causes the charge to be transferred in the reverse direction through the external circuit. Similarly, an instantaneous current from the second electrode plate 32 to the first electrode plate 31 is generated in the external circuit. At this time, the power generation component 3 completes a complete working cycle and generates two opposite currents. The external circuit of the power generation component 3 is externally connected to the rectifier module 6, and the generated current is rectified, stored and distributed by the rectifier module 6.

[0029] In order to enable the power generation device to be used in a scenario where sound absorption and sound insulation are required, the power generation device also includes a mounting frame group 4 and a basic frame 5. The mounting frame group 4 includes a main outer ring frame 41 installed on the outside of the orifice plate 1. There is a gap between the main outer ring frame 41 and the resonance chamber 2 and the power generation component 3, so that the resonance chamber 2 and the power generation component 3 have a larger vibration amplitude. The basic frame 5 is installed on a building, such as a wall or a ceiling. The main outer ring frame 41 is fitted with the basic frame 5 and then laid on the building. It should be noted that the movable part 33 in the laid power generation component 3 is in contact with the first electrode plate 31 in a stationary state. Because the first electrode plate 31 generates a larger vibration amplitude, the movable part 33 can be better driven to move; It can be seen that the laying power generation device usually has two states, namely vertical laying and horizontal laying. According to the usage scenario and the limitation that the movable part 33 contacts the first electrode plate 31 in the static state, it is known that the power generation device is usually not laid on the ground in the horizontal laying. However, in the use requirement of laying on the ground, the power generation device can still achieve the required effect, and it only needs to make the movable part 33 contact the second electrode plate 32 in the static state. Therefore, the use of power generation devices in scenarios where sound absorption and sound insulation are required includes two parts: one is the adaptability of the power generation device itself to use, and the other is the installation of the power generation device on the building.

[0030] First, the first part, that is, the adaptability of the power generation device itself to use: in the horizontal laying, in order to prevent the movable parts 33 from moving and gathering and thus affecting the activity effect, the mounting frame group 4 also includes an inner limit frame 42, which is installed in the inner cavity of the middle frame 34, and is used to limit the range of movement of the movable parts 33 in the inner cavity. The inner limit frame 42 includes a grid 421 and a limit pin 422 installed on the grid 421. There are gaps between the grid 421 and the limit pin 422 and the first electrode plate 31 and the second electrode plate 32. The limit pin 422 is arranged around the movable part 33 based on a single movable part 33; It should be noted that the spacing between the limit pins 422 around a single movable part 33 is smaller than the diameter of the movable part 33. At the same time, at least one limit pin 422 is shared between two adjacent movable parts 33. The first electrode plate 31 is used as a plane coordinate system. The plane coordinate system includes an X-axis and a Y-axis. The movable parts 33 are regularly arranged and distributed on the plane coordinate system. The distance between two adjacent movable parts 33 is set to L1, the spacing between the limit pins 422 around a single movable part 33 is set to L2, the number of the limit pins 422 around a single movable part 33 is set to N, the radius of a single movable part 33 is set to R, and the distance between two adjacent movable parts 33 is set to L1. There is a relationship of R / 2≤L1≤3R between the parts 33, and L2<2R, thereby limiting the arrangement pattern of the movable parts 33; in R / 2≤L1<2R, 4≤N≤8, and the case of N=4 is usually adopted, that is, 4 limit pins 422 are evenly distributed around a single movable part 33 in the plane coordinate system; in 2R≤L1≤3R, 6≤N, in this embodiment, L1=2R, N=8, in the plane coordinate system, there are 8 limit pins 422 around a single movable part 33, and they are evenly distributed in a regular octagon, thereby preventing the movable parts 33 from moving and gathering during lateral laying, and not affecting the vibration activity of the movable parts 33.

[0031] In vertical laying, in order to allow the movable part 33 to contact the first electrode plate 31 in advance, the end of the limit pin 422 is tapered, and the movable part 33 slides downward along the tapered limit pin 422 and then contacts the first electrode plate 31. In order to make the movable part 33 smoother in subsequent vibration and rolling, the limit pins 422 between the rows of movable parts 33 are arranged on the same connecting line, and the connecting line is parallel to the X-axis or the Y-axis. In addition, the mounting frame group 4 also includes a ramp frame 43, and slots are provided on both sides of the middle link frame 34. The ramp frame 43 passes through the slot of the middle link frame 34 and enters the middle link frame 34 to engage with the limit pin 422. The two sides of the ramp frame 43 are installed on the main outer ring frame 41, so that the ramp frame 43 is buckled on several limit pins 422 on the same connecting line, and the outer side of the ramp frame 43 has an inclined surface, and the inclined surface of the ramp frame 43 is used to support the movable part 33 when the power generation component 3 is vertically arranged. The inclined surface of the ramp frame 43 points to the first electrode plate 31, so that the movable part 33 slides downward along the inclined surface of the ramp frame 43 and then contacts the first electrode plate 31. And because it is a straight inclined surface, there will not be as much drop as the arranged limit pins 422, and the landing point will not be single, so that the movable part 33 can move more smoothly.

[0032] It can be known that the mounting frame assembly 4 and the ramp frame 43 are made of the same material as the movable member 33 .

[0033] Then comes the second part, i.e. the installation of the power generation device on the building body. The basic skeleton 5 is in the shape of a strip, and a concave inner engaging cavity 5a is provided in the middle of the basic skeleton 5. The main outer ring frame 41 is provided with an engaging tooth 412, which is embedded and engaged in the inner engaging cavity 5a. The basic skeleton 5 is provided with a positioning wing 51, and the main outer ring frame 41 is provided with a positioning tooth 411, which is engaged with the positioning wing 51. Usually, the positioning tooth 411 and the engaging tooth 412 can be combined and arranged. However, in this embodiment, there is an angle between the positioning tooth 411 and the engaging tooth 412, and the engaging tooth 412 is parallel to the strip-shaped basic skeleton 5, thereby separating the force-bearing and fixing parts, and the basic skeleton 5 is provided with a snap-fit ​​structure for snapping with the main outer ring frame 41 so that the main outer ring frame 41 is installed on the basic skeleton 5; Specifically, a side movable cavity 5b is provided on the side wall of the inner engaging cavity 5a, a buckle groove 412a is provided on the engaging tooth 412, and a buckle structure is arranged in the side movable cavity 5b. The buckle structure includes a buckle head 53 and an elastic twisting member 54. The buckle head 53 is installed in the side movable cavity 5b through the twisting member 54. The buckle head 53 is inclined to the side of the engaging tooth 412. The engaging tooth 412 moves into the inner engaging cavity 5a to push the buckle head 53. When the buckle groove 412a moves to the position of the buckle head 53, the buckle head 53 is reset, so that the buckle groove 412a and the buckle head 53 are matched and buckled. An elastic boosting strip 52 is provided at the bottom of the inner engaging cavity 5a of the basic skeleton 5, and the elastic boosting strip 52 abuts against the engaging tooth 412 so that the buckle groove 412a and the buckle head 53 abut against each other.

[0034] Moreover, in order to achieve better sound insulation and sound absorption effects, the power generation devices are arranged relatively closely, so there is basically no gap to prepare for the disassembly of the power generation devices. Therefore, in the present embodiment, one side of the buckle head 53 adjacent to the inclined side surface is also inclined, and the two inclined side surfaces are narrowed and converged from the bottom end of the buckle head 53 to the top end of the buckle head 53, and a conical clamping portion 53a is provided at the converging point, and a side groove 412b extending from the buckle groove 412a to the outside of the inner engaging cavity 5a is provided on the engaging tooth 412, and the entrance of the side groove 412b points to the conical clamping portion 53a, and the side groove 412b extends obliquely and the horizontal height at which the outlet is located does not interfere with the buckle groove 412a, that is, it avoids the edge area of ​​the buckle groove 412a, and a disengagement groove 412c is provided at the outlet of the side groove 412b. It is parallel to the movement direction of the engaging tooth 412 and extends to the end of the engaging tooth 412. In addition, at least two elastic twisting parts 54 are provided between the buckle head 53 and the side movable chamber 5b. The power generation device continues to be pushed into the inner engaging chamber 5a and squeezes the elastic booster strip 52, so that the buckle head 53 enters the side groove 412b. The buckle head 53 entering the side groove 412b is twisted into the side movable chamber 5b. The two elastic twisting parts 54 can better twist the buckle head 53 until the conical clamping part 53a of the buckle head 53 enters the disengagement groove 412c, so that the buckle head 53 is twisted to the extent that it does not interfere with the buckle groove 412a in the movement direction of the engaging tooth 412. At this time, when the power generation device is pulled out, the conical clamping part 53a of the buckle head 53 slides out of the disengagement groove 412c, and the buckle head 53 will not block the buckle groove 412a.

[0035] In summary, in the specific implementation, the indoor environment needs to be arranged by laying the power generation device vertically on the wall and horizontally on the ceiling, and the basic frame 5 is installed on the ceiling and the wall: First, the main outer ring frame 41 carrying the orifice plate 1, the resonance chamber 2 and the power generation component 3 is inserted into the basic frame 5 of the ceiling in such a way that the positioning teeth 411 are aligned with the positioning wings 51 and the bite teeth 412 are aligned with the inner engaging cavity 5a, and the bite teeth 412 move into the inner engaging cavity 5a to push the buckle head 53 open, and when the buckle groove 412a moves to the buckle head 53 position, the buckle head 53 is reset, so that the buckle groove 412a is aligned with the buckle The head 53 is buckled with, the main outer ring frame 41 is provided with at least four bite teeth 412, and the basic frame 5 is provided with at least four sets of buckle mechanisms in cooperation therewith, so that the power generation device is buckled and hung on the ceiling; second, the ramp frame 43 is inserted into the middle frame 34 and is clamped on the limit pin 422, and then the two sides of the ramp frame 43 are fixed on the main outer ring frame 41, and the main outer ring frame 41 is in a horizontal position, and the main outer ring frame 41 of the power generation device is clamped into the basic frame 5 of the wall in a manner that the positioning teeth 411 are aligned with the positioning wings 51 and the bite teeth 412 are aligned with the inner clamping cavity 5a; After the orifice plate 1 absorbs the sound waves, the movable part 33 is driven to move through the vibration of the orifice plate 1, the resonance chamber 2 and the power generation component 3, and a current is generated between the external circuits of the first electrode plate 31 and the second electrode plate 32. The current is rectified and utilized by the rectifier module 6. When the power generation device is damaged, the main outer ring frame 41 of the power generation device is further pushed into the basic skeleton 5 to further compress the elastic booster strip 52, and the buckle head 53 enters the side groove 412b to twist the buckle head 53 into the side active cavity 5b. The two elastic torsion parts 54 can make the buckle head 53 twist better until the conical clamping part 53a of the buckle head 53 enters the disengagement groove 412c from the side groove 412b, and then the power generation device is pulled out, and the conical clamping part 53a of the buckle head 53 slides out from the disengagement groove 412c, and the buckle head 53 will not block the buckle groove 412a.

[0036] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
