Description

Technical Field

[0001] The utility model relates to the technical field of deep waterproof loudspeakers, in particular to a self-depressurized waterproof loudspeaker with a nuclear pore membrane waterproof and breathable sound-generating ball top. Background Art

[0002] Our company's first generation of self-pressure-releasing waterproof speakers are mainly used in electronic products that need to work underwater. They have deep waterproof and efficient ventilation functions. They can release the gas generated by the internal working heat of electronic products through waterproof speakers to ensure the consistency of pressure inside and outside the electronic products. They are also deeply waterproof. For example, when diving or swimming, they can effectively prevent external water from wetting the internal electronic components of electronic products to ensure the normal operation of electronic products. The self-pressure-releasing waterproof speaker mainly includes the speaker magnetic circuit, speaker coil, speaker vibration membrane, sound ball top, etc. The sound ball top is an important sound-generating device of the speaker. The sound ball top is a component that converts electrical signals into mechanical vibrations and generates sound output. It is an important component of the speaker. Its working principle: such as Fig.15 As shown, in the speaker, the sound-generating dome is mounted on the speaker diaphragm 12 and is installed in the magnetic field of the drive unit together with the speaker diaphragm 12. It is usually fixed between magnets and connected to the voice coil (speaker coil 11). When current passes through the voice coil, it will be affected by the magnetic field and start to move. As the audio signal changes, the voice coil and the diaphragm drive the sound-generating dome to move at a corresponding frequency and amplitude, thereby generating sound waves and making sounds.

[0003] In order to achieve the waterproof and pressure relief function, a vent area is provided on the top of the sound ball 15, and the vent area is covered with a waterproof and breathable membrane 16 to achieve the waterproof and breathable effect. After it is installed in the electronic product housing 1, the speaker and the electronic components inside the electronic product will generate heat when working, and the air in the rear sound cavity 3 begins to expand and generate air pressure. The pressure value continues to increase. When the exhaust volume of the pressure relief hole 13 of the rear sound cavity 3 is insufficient, the expanding gas begins to compress the speaker diaphragm, causing the diaphragm to vibrate unbalancedly, generating vibration and small sound. The above phenomenon is more obvious in the speaker with a closed rear sound cavity. The current waterproof and breathable membrane mainly uses ePtfe waterproof and breathable membrane. With actual use, it is gradually found that the waterproof and sound-generating assembly composed of ePtfe waterproof and breathable membrane and the sound ball top has many problems:

[0004] Our company's first-generation self-pressure-relieving waterproof speakers have an air hole area on the top of the sound ball 15 to achieve the waterproof and pressure-relieving function. The air hole area is covered with a waterproof and breathable membrane 16 to achieve a waterproof and breathable effect. After it is installed in the electronic product case 1, the speaker and the electronic components inside the electronic product will generate heat when working, and the air in the rear sound cavity 3 will begin to expand and generate air pressure. The pressure value continues to increase. When the exhaust volume of the pressure relief hole 13 of the rear sound cavity 3 is insufficient, the expanding gas begins to compress the speaker diaphragm, causing the diaphragm to vibrate unbalancedly, producing vibration and small sound. The above phenomenon is more obvious in the speakers with closed rear sound cavities. The first-generation waterproof and breathable membrane uses an ePtfe waterproof and breathable membrane. With actual use, it is gradually found that the waterproof and sound-generating components composed of the ePtfe waterproof and breathable membrane and the sound ball top have many problems:

[0005] 1. The ePtfe waterproof breathable membrane is obtained by stretching polytetrafluoroethylene (PTFE) material. The stretched membrane is soft and has insufficient tensile strength. The ePtfe material has almost no rigidity. Therefore, the finished ePtfe waterproof breathable membrane needs to be supported and protected by non-woven fabrics. When applied to waterproof products with a depth of more than 50 meters, once the water pressure is greater than 500KPa, there will be a stratification problem between the ePtfe waterproof breathable membrane and the non-woven fabric. Once stratified, the ePtfe waterproof breathable membrane will be easily torn in an instant, causing water to enter the electronic products;

[0006] Second, in order to meet the air permeability requirements of self-decompression waterproof speaker carriers used in smart watches, mobile phones and other electronic products, to achieve consistency between internal and external pressures, and to meet the accurate detection of altitude by air sensors, it is necessary to ensure the consistency of the gas flow through the ePtfe waterproof breathable membrane. However, due to the limitations of its production and stretching process into micropores, the micropores on the ePtfe waterproof breathable membrane are irregularly distributed, the consistency of the gas flow is poor, and the gas flow tolerance per unit time is large. When used on products with built-in air pressure sensors, the air pressure sensor has a certain probability of misjudgment;

[0007] 3. The first generation of self-pressure-releasing waterproof speakers uses a rigid, light and thin sheet (such as PEI / PEN / PET / PI or even aluminum foil, copper foil and other rigid sheets. The air holes need to be opened by laser or punched mechanically. Later, the sound ball and the ePtfe waterproof breathable membrane need to be precisely aligned. When laminating, due to the requirements of the waterproof level, the surface of the sound ball needs to be plasma cleaned and other complex processes before it can be integrated with the ePtfe waterproof breathable membrane to achieve the function of deep waterproof and breathable. The hole opening and production process are very complicated. Utility Model Content

[0008] The purpose of the utility model is to solve the above-mentioned technical problems and provide a self-pressure relief waterproof speaker with a nuclear pore membrane waterproof and breathable sound ball top. The sound ball top is made of a nuclear pore membrane. Compared with the first generation of self-pressure relief waterproof speakers, which use a traditional sound ball top superimposed with an EPTFE waterproof and breathable membrane to achieve the waterproof and breathable function, the production process is simple and the cost is low. The nuclear pore membrane waterproof and breathable sound ball top has high mechanical strength and good toughness, which meets the requirements of deep waterproof products for the toughness of the waterproof and breathable membrane and the ability to withstand high pressure. The nuclear pore membrane has controllable pore density, consistent pore size, regular pore shape, very good air flow consistency, and is very stable. It can fully meet the needs of electronic products with built-in air pressure sensors and electronic products that accurately measure the current altitude. It is a precision microporous membrane material that can reach nano-level micropores and has deep waterproof and breathable functions.

[0016] 1. Compared with the traditional self-pressure-relieving waterproof speaker, the nuclear pore membrane waterproof and breathable sound dome is made of nuclear pore membrane. It is no longer a component composed of a sound dome and an ePtfe waterproof and breathable membrane.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] This embodiment provides a self-decompression waterproof speaker with a nuclear pore membrane waterproof and breathable sound-generating dome. Figures 1 to 16 As shown, it includes a nuclear pore membrane waterproof breathable sound ball top 6, a speaker bracket 7, a speaker cover 8 and a concave vibration membrane 12. The nuclear pore membrane waterproof breathable sound ball top 6 is composed of a nuclear pore membrane, and the nuclear pore membrane waterproof breathable sound ball top 6 has an oleophobic and hydrophobic layer 15. A speaker magnetic circuit 10 is installed at one end of the speaker bracket 7, and a speaker coil 11 is arranged in the speaker magnetic circuit 10 or the speaker coil 11 is arranged inside and outside the speaker magnetic circuit 10. The speaker coil 11 is fixedly connected to the concave vibration membrane 12 or the nuclear pore membrane waterproof breathable sound ball top 6. An air circulation area 14 is arranged on the concave vibration membrane 12, and the nuclear pore membrane waterproof breathable sound ball top 6 covers and is fixed on the air circulation area 14. The speaker cover 8 presses the edge of the concave vibration membrane 12 on the other end of the speaker bracket 7.

[0039] Nuclear pore membrane, also known as heavy ion microporous membrane, is a kind of precision microporous membrane material, which is formed by punching holes and etching holes in insulating materials by heavy charged particles. When the etching range of heavy charged particles in the insulating material film is greater than the thickness of the film, the radiation damage generated on each vertically incident heavy charged particle path is etched to form nano-scale micropores that penetrate the insulation, and then covered with an oleophobic and hydrophobic layer, which has the functions of deep waterproofing and air permeability. The gas flowing through the ventilation flow area 14 can pass through the nuclear pore membrane, but the water from the outside cannot pass through the nuclear pore membrane. The nuclear pore membrane has the characteristics of controllable pore density, uniform and controllable pore size, regular pore shape, smooth membrane surface and no fiber shedding. The nuclear pore membrane has high mechanical strength and good toughness. It can effectively withstand the unbroken deformation of deep water pressure of more than 50 meters. No additional non-woven fabric support is required. Moreover, the nuclear pore membrane waterproof and breathable sound-generating ball top 6 composed of the nuclear pore membrane does not need to be divided into two parts, which simplifies the manufacturing process. The nuclear pore membrane is a multi-nanoporous material formed by etching after high-energy heavy ions penetrate the polymer film. The hole opening process is simple, stable and accurate. The nuclear pore membrane waterproof and breathable sound-generating ball top corresponding to the air circulation area of ​​the concave vibration membrane has an oleophobic and hydrophobic layer, and the waterproof level can reach more than 50 meters.

[0040] (1) Working principle:

[0041] When the nuclear pore membrane waterproof breathable sound ball top self-decompression waterproof speaker is applied to electronic products with deep waterproof requirements, refer to Figure 1 and Figure 2 As shown, the electronic product comprises an electronic product housing 1, in which a mounting cavity is provided, in which a waterproof speaker in Embodiment 2 is provided, the waterproof speaker divides the mounting cavity into a front cavity 2 and a rear cavity 3, the end of the speaker bracket 8 equipped with a speaker cover 7 faces the front cavity 2, the end of the speaker bracket 8 equipped with a speaker base 9 faces the rear cavity 3, the front cavity 2 is provided with a sound outlet 4, the sound outlet 4 corresponds to the concave vibration membrane 12, the rear cavity 3 is used to install the electronic components of the electronic product, the front cavity 2 is provided with a dustproof net 5, and the dustproof net 5 is used to cover the sound outlet 4. The rear cavity 3 has a pressure relief type rear cavity, in which a pressure relief hole 13 is provided, and a closed rear cavity, that is, there is no pressure relief hole 13.

[0042] When electronic products are in use, the electronic components and speakers continue to heat up or heat up rapidly, the air in the back cavity 3 expands, and the pressure increases. The expanded gas in the back cavity 3 enters the inner ring of the speaker bracket 8, and then flows from the air circulation area 14 of the concave vibration membrane 12 to the nuclear pore membrane waterproof and breathable sounding ball top 6. Because the nuclear pore membrane waterproof and breathable sounding ball top 6 is composed of a nuclear pore membrane, it will be discharged through the nuclear micropores 9 of the nuclear pore membrane waterproof and breathable sounding ball top 6, realizing automatic pressure relief, eliminating the gas pressure generated by the working heat of the machine, protecting the normal working balance of the speaker vibration system, and keeping the back cavity 3 of the casing consistent with the external atmospheric pressure in real time without changing the original electroacoustic characteristics of the speaker.

[0043] (2) The nuclear pore membrane production process is divided into two steps:

[0044] The first step is to use a large nuclear facility to accelerate the nuclei to very high energy to bombard a plastic film of a certain thickness. When the etching range of heavy charged particles in the insulating material film is greater than the film thickness, the radiation damage generated on each vertically incident heavy charged particle path is about several nanometers in diameter. With such a radiation-damaged film, we can understand that there can be many small holes of several nanometers on the surface of the film. The second step is to etch the above radiation-damaged film, which can turn the radiation-damaged channels on the film into straight-through nuclear micropores 9. By controlling the irradiation conditions and etching conditions, nuclear pore membranes with different pore densities and different pore diameters can be obtained.

[0045] The nuclear pore membrane has good rigidity and temperature performance. It has four main features: first, the pore density is controllable, from 1 small hole per square centimeter to 10 billion small holes; second, the pore size is uniform, all the small holes have the same diameter, because when the nucleus is accelerated, it has a single energy and a single mass, so all the pore sizes are the same; third, the pore size range is very wide and precisely controllable, from a few nanometers to dozens of microns, spanning four orders of magnitude that are invisible to the naked eye; fourth, it has deep waterproof and breathable functions; fifth, the nuclear pore membrane has high mechanical strength, good toughness, and a smooth membrane surface without fiber shedding.

[0046] Further, in this embodiment, if Figures 1 to 16 As shown, we upgrade the thickness of the nuclear pore membrane waterproof breathable sounding ball top 6 composed of the nuclear pore membrane to a certain thickness, which has both a certain rigidity and waterproof and breathable functions, and make it into a nuclear pore membrane waterproof breathable sounding ball top 6 of a self-pressure relief waterproof speaker, and apply it to the self-pressure relief waterproof speaker to make a self-pressure relief waterproof speaker with a nuclear pore membrane waterproof breathable sounding ball top. For a self-pressure relief waterproof speaker with a power less than 0.5W, the thickness of the nuclear pore membrane waterproof breathable sounding ball top 6 is usually above 12μm. For a self-pressure relief waterproof speaker with a power greater than 0.5W, the thickness of the nuclear pore membrane waterproof breathable sounding ball top 6 is usually above 50μm. The nuclear pore membrane waterproof breathable sounding ball top 6 has an oleophobic and hydrophobic layer 15, and the oleophobic and hydrophobic layer 15 is located above or below or both above and below the nuclear pore membrane waterproof breathable sounding ball top 6.

[0047] Further, in this embodiment, if Figures 1 to 16 As shown, the nuclear pore membrane waterproof breathable sounding ball top 6 is composed of a layer of nuclear pore membrane or multiple layers of nuclear pore membrane. That is, the nuclear pore membrane waterproof breathable sounding ball top 6 can be composed of only a single layer of nuclear pore membrane, or can be composed of multiple layers of nuclear pore membrane.

[0048] In this embodiment, Figures 1 to 16 As shown, the nuclear pore membrane is made of a rigid film.

[0049] Further, in this embodiment, if Figures 1 to 16 As shown, the rigid film can be made of rigid films such as PEI, PEN, PET, PI, PC, PEEK, etc.

[0050] Among them, PEI's full English name is Polyetherimide, and its Chinese name is polyetherimide;

[0051] PEN is the full name of Polyethylene Naphthalate in English, and its Chinese name is Polyethylene Naphthalate.

[0052] PET film is also known as high temperature resistant polyester film;

[0053] PI is the full name of Polyimide Film in English, and its Chinese name is polyimide film;

[0054] PC is the full name of Polycarbonate in English, and its Chinese name is polycarbonate;

[0055] The full English name of PEEK is Polyetheretherketone, and its Chinese name is polyetheretherketone.

[0056] In this embodiment, Figures 1 to 16 As shown, the nuclear pore membrane waterproof breathable sound ball top 6 is a flat sheet structure, a convex sheet structure or a concave sheet structure. The flat sheet structure means that the nuclear pore membrane waterproof breathable sound ball top 6 is a flat membrane as a whole, refer to Figures 1 to 11 The convex sheet structure is a flat structure with the middle part convex upward. Figure 12 to Figure 13 The concave sheet structure is a flat structure with a convex middle part. Fig.14 .

[0057] Further, in this embodiment, if Figures 1 to 16 As shown, patterns or designs can also be provided on the top 6 of the nuclear pore membrane waterproof and breathable sound-generating ball to meet the functional requirements of the speaker to enhance the mid- and high-frequency characteristics.

[0058] Further, in this embodiment, if Figures 1 to 16 As shown, the nuclear pore membrane waterproof breathable sound ball top 6 is fixedly connected to the air circulation area by bonding, welding or wrapping. The embedding method is such as injection molding wrapping, that is, when the concave vibration membrane 12 is injected, the edge of the nuclear pore membrane waterproof breathable sound ball top 6 is wrapped inside.

[0059] In this embodiment, Figures 1 to 16 As shown, when the concave vibration membrane 12 is fixedly connected to the speaker coil 11, the positional relationship between the concave vibration membrane 12, the speaker coil 11, and the nuclear pore membrane waterproof breathable sound ball top 6 can be divided into two types: one is that the concave vibration membrane 12 is located between the speaker coil 11 and the nuclear pore membrane waterproof breathable sound ball top 6, such as Figure 1 , Figure 2 , Figure 6 , Figure 7 As shown, one is that the concave vibration membrane 12 and the nuclear pore membrane waterproof and breathable sound-generating ball top 6 are both located on one side of the speaker coil 11, such as Figure 6 shown.

Of course, they can also be shaped like special shapes, which are not limited here.
