Description

Technical Field

[0001] This invention relates to the field of deep waterproof loudspeaker technology, and in particular to a self-relieving waterproof loudspeaker with a nuclear pore membrane waterproof and breathable sound-emitting dome. Background Technology

[0002] Our company's first-generation self-pressure-relieving waterproof loudspeaker is mainly used in electronic products that need to operate underwater. It features deep waterproofing and efficient ventilation, allowing gas generated by heat during operation to escape, ensuring consistent internal and external pressure. It also provides deep waterproofing, effectively preventing water from wetting internal electronic components during diving or swimming, thus ensuring normal operation. The self-pressure-relieving waterproof loudspeaker mainly includes a loudspeaker magnetic circuit, loudspeaker coil, loudspeaker diaphragm, and sound-generating dome. The sound-generating dome is a crucial sound-producing component, converting electrical signals into mechanical vibrations to generate sound output. It is an essential part of the loudspeaker. Its working principle is as follows: Figure 15 As shown, in a loudspeaker, the sound-emitting dome is mounted on the loudspeaker diaphragm 12, and together with the loudspeaker diaphragm 12, it is mounted in the magnetic field of the drive unit, typically fixed between magnets and connected to the voice coil (loudspeaker coil 11). When current passes through the voice coil, it is affected by the magnetic field and begins to move. As the audio signal changes, the voice coil and diaphragm drive the sound-emitting dome to move at a corresponding frequency and amplitude, thereby generating sound waves and emitting sound.

[0003] To achieve waterproof and pressure-relief functions, the sound-generating dome 15 has a vent area covered by a waterproof and breathable membrane 16. After installation inside the electronic product housing 1, the speaker and internal electronic components generate heat during operation. This causes the air in the rear acoustic chamber 3 to expand, creating air pressure. As the pressure increases, if the pressure relief vent 13 in the rear acoustic chamber 3 fails to release enough air, the expanding gas begins to compress the speaker diaphragm, causing unbalanced diaphragm vibration and resulting in vibration and low-frequency sounds. This phenomenon is more pronounced in speakers with sealed rear acoustic chambers. Currently, the waterproof and breathable membrane mainly uses ePtFe waterproof and breathable membrane. However, with practical use, it has become increasingly apparent that the waterproof sound-generating component composed of the ePtFe waterproof and breathable membrane and the sound-generating dome has several problems.

[0004] Our company's first-generation self-relieving waterproof loudspeaker features a vent area on the sound-emitting dome 15 to achieve waterproof and pressure-relieving functions. This vent area is covered by a waterproof and breathable membrane 16 to achieve both waterproof and breathable effects. After installation inside the electronic product housing 1, the loudspeaker and internal electronic components generate heat during operation. This causes the air in the rear acoustic chamber 3 to expand, creating air pressure. As the pressure increases, if the venting capacity of the pressure relief holes 13 in the rear acoustic chamber 3 is insufficient, the expanding gas begins to compress the loudspeaker diaphragm, causing unbalanced diaphragm vibration and resulting in vibration and low-frequency sounds. These phenomena are more pronounced in loudspeakers with sealed rear acoustic chambers. The first-generation waterproof and breathable membrane uses an ePtFe waterproof and breathable membrane. However, with actual use, several problems have been discovered with the waterproof sound-emitting component consisting of the ePtFe waterproof and breathable membrane and the sound-emitting dome.

[0005] 1. ePTFE waterproof and breathable membranes are made by stretching polytetrafluoroethylene (PTFE) material. This stretched membrane is soft and lacks tensile strength. ePTFE material has almost no rigidity. Therefore, finished ePTFE waterproof and breathable membranes need to be supported and protected with non-woven fabric. When applied to waterproof products with a depth of more than 50 meters, if the water pressure exceeds 500 kPa, delamination will occur between the ePTFE waterproof and breathable membrane and the non-woven fabric. Once delamination occurs, the ePTFE waterproof and breathable membrane can be easily torn instantly, leading to water ingress into electronic products.

[0006] 2. In order to meet the air permeability requirements of self-releasing waterproof speaker carriers used in various electronic products such as smartwatches and mobile phones, and to achieve consistency between internal and external pressures, so as to meet the accurate detection of altitude by air sensors, it is necessary to ensure the consistency of gas flow through the ePtfe waterproof and breathable membrane. However, due to the limitations of its production process of stretching into micropores, the micropores on the ePtfe waterproof and breathable membrane are irregularly distributed, resulting in poor consistency of gas flow and a large tolerance in gas flow per unit time. When used in products with built-in air pressure sensors, this can lead to a certain probability of false judgment by the air pressure sensors.

[0007] Third, the sound-emitting dome of the first-generation self-releasing waterproof speaker is made of rigid, thin sheets (such as PEI / PEN / PET / PI, or even aluminum foil, copper foil, etc.). Its vent holes need to be laser-drilled or mechanically punched. Afterwards, the sound-emitting dome and the ePtfe waterproof and breathable membrane need to be precisely bonded together. Due to the requirements of the waterproof level, the surface of the sound-emitting dome often needs to undergo complex processes such as plasma cleaning treatment to form a whole with the ePtfe waterproof and breathable membrane to achieve the function of deep waterproof and breathable function. The drilling and manufacturing process are very complicated. Summary of the Invention

[0008] The purpose of this invention is to solve the aforementioned technical problems and provide a self-releasing waterproof speaker with a core-porous membrane waterproof and breathable sound-emitting dome. The sound-emitting dome is made of a core-porous membrane. Compared to the first-generation self-releasing waterproof speaker, which uses a traditional sound-emitting dome layered with an EPTFE waterproof and breathable membrane to achieve waterproof and breathable functions, this method is simpler and less costly. The core-porous membrane waterproof and breathable sound-emitting dome has high mechanical strength and good toughness, meeting the requirements of deep waterproof products for the toughness and high pressure resistance of the waterproof and breathable membrane. The core-porous membrane has controllable pore density, consistent pore size, regular pore shape, and excellent and stable airflow consistency. This fully meets the needs of electronic products with built-in air pressure sensors, accurately measuring the current altitude. It is a precision microporous membrane material capable of achieving nanoscale micropores, possessing both deep waterproof and breathable functions.

[0009] To achieve the above objectives, the present invention provides the following solution: The present invention discloses a self-pressure relief waterproof loudspeaker with a nuclear pore membrane waterproof and breathable sound-emitting dome, comprising a loudspeaker support (8), a concave diaphragm (12), and a nuclear pore membrane waterproof and breathable sound-emitting dome (6). The nuclear pore membrane waterproof and breathable sound-emitting dome (6) is composed of a nuclear pore membrane and has an oleophobic and hydrophobic layer (15). A loudspeaker magnetic circuit (10) is installed at one end of the loudspeaker support (8). The speaker is provided with a speaker coil (11) inside and outside. The speaker coil (11) is fixedly connected to the concave diaphragm (12) or the sound-emitting core membrane waterproof and breathable sound-emitting dome (6). The concave diaphragm (12) is provided with an air circulation area. The concave diaphragm (12) is provided with the core membrane waterproof and breathable sound-emitting dome (6) covering and fixed in the air circulation area. The speaker cover (7) presses the edge of the concave diaphragm (12) against the other end of the speaker bracket.

[0010] Preferably, the waterproof and breathable nuclear pore membrane waterproof and breathable sound-emitting dome (6) is made of a nuclear pore membrane, and the nuclear pore membrane waterproof and breathable sound-emitting dome (6) has an oleophobic and hydrophobic layer (15), which is located above, below, or both above and below the nuclear pore membrane waterproof and breathable sound-emitting dome (6).

[0011] Preferably, the nuclear pore membrane waterproof, breathable, and sound-emitting dome (6) is composed of one or more nuclear pore membranes.

[0012] Preferably, the waterproof, breathable, and sound-emitting dome (6) of the nuclear pore membrane is a planar sheet structure, a concave sheet structure, or a convex sheet structure.

[0013] Preferably, the waterproof, breathable, and sound-emitting dome (6) of the nuclear pore membrane is provided with patterns or designs.

[0014] Preferably, the waterproof and breathable sound-emitting dome (6) of the core pore membrane is fixedly connected to the concave vibrating membrane (12) by bonding, welding or injection molding.

[0015] The present invention achieves the following technical effects compared to the prior art:

[0016] 1. Compared to traditional self-relieving waterproof loudspeakers, the nuclear pore membrane waterproof and breathable sound dome is made of a nuclear pore membrane. It is no longer a component consisting of a sound dome and an ePtfe waterproof and breathable membrane. It eliminates the original complex process of opening multiple holes in the ordinary dome and then precisely bonding the ePtfe waterproof and breathable membrane, and also eliminates the expensive ePtfe waterproof and breathable membrane. This greatly optimizes the production process and reduces costs.

[0017] 2. The core-pore membrane waterproof, breathable, and sound-emitting dome has high mechanical strength and good toughness, meeting the requirements of deep waterproof products for the toughness of the waterproof and breathable membrane and the pressure resistance of more than 500KPA over 50 meters of waterproof pressure.

[0018] 3. The nuclear pore membrane waterproof, breathable, and sound-emitting dome features controllable pore density, uniform pore size, regular pore shape, smooth membrane surface without fiber shedding, and excellent airflow consistency. It is a precision microporous membrane material that can achieve nanoscale micropores, possessing deep waterproof and breathable functions, 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. Attached Figure Description

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] This embodiment provides a self-pressure-relieving waterproof loudspeaker with a nuclear pore membrane waterproof and breathable sound-emitting dome, such as Figures 1 to 16 As shown, the system includes a porous membrane waterproof and breathable sound-generating dome 6, a speaker bracket 7, a speaker cover 8, and a concave diaphragm 12. The porous membrane waterproof and breathable sound-generating dome 6 is composed of a porous membrane and has an oleophobic and hydrophobic layer 15. A speaker magnetic circuit 10 is installed at one end of the speaker bracket 7. A speaker coil 11 is provided inside the speaker magnetic circuit 10, or a speaker coil 11 is provided both inside and outside the speaker magnetic circuit 10. The speaker coil 11 is fixedly connected to the concave diaphragm 12 or the porous membrane waterproof and breathable sound-generating dome 6. An air circulation area 14 is provided on the concave diaphragm 12. The porous membrane waterproof and breathable sound-generating dome 6 covers and is fixed on the air circulation area 14. The speaker cover 8 presses the edge of the concave diaphragm 12 against the other end of the speaker bracket 7.

[0039] Nuclear pore membranes, also known as heavy ion microporous membranes, are precision microporous membrane materials. They are formed by drilling and etching pores in an insulating material using heavy charged particles. When the etchable range of heavy charged particles in the insulating film exceeds the film thickness, the radiation damage generated along the path of each vertically incident heavy charged particle is etched to form nanoscale micropores that penetrate the insulation. This allows for the application of an oleophobic and hydrophobic layer, providing both deep waterproofing and breathability. Gas flowing through the ventilation zone 14 can pass through the nuclear pore membrane, but external water cannot. Featuring controllable pore density, uniform and controllable pore size, regular pore shape, and a smooth membrane surface without fiber shedding, the nucleoporous membrane boasts high mechanical strength and good toughness. It can effectively withstand water pressure exceeding 50 meters without fracturing or deformation, eliminating the need for additional non-woven fabric support. Furthermore, the nucleoporous membrane waterproof, breathable, and sound-generating dome 6, constructed from this membrane, eliminates the need for separate components, simplifying the manufacturing process. The nucleoporous membrane is a multi-nanoporous material formed by etching after high-energy heavy ions penetrate a polymer film; the opening process is simple, stable, and precise. The concave vibrating membrane's airflow area corresponds to a nucleoporous membrane waterproof, breathable, and sound-generating dome with an oleophobic and hydrophobic layer, achieving a waterproof rating of over 50 meters.

[0040] (1) Working principle:

[0041] When applying this core-pore membrane waterproof, breathable, sound-emitting dome self-relieving waterproof speaker to electronic products requiring deep waterproofing, refer to... Figure 1 and Figure 2 As shown, the electronic product includes an electronic product casing 1, which has a mounting cavity. The mounting cavity houses the waterproof speaker from Embodiment 2, which divides the mounting cavity into a front cavity 2 and a rear cavity 3. One end of the speaker bracket 8, on which a speaker cover 7 is mounted, faces the front cavity 2, while the other end, on which a speaker base 9 is mounted, faces the rear cavity 3. The front cavity 2 has a sound outlet 4, which corresponds to a concave diaphragm 12. The rear cavity 3 is used to mount the electronic components of the electronic product. A dustproof mesh 5 is provided inside the front cavity 2 to cover the sound outlet 4. The rear cavity 3 can be a pressure-relief type with a pressure relief hole 13, or a sealed type without a pressure relief hole 13.

[0042] When electronic products are in use, the electronic components and speakers continuously or rapidly heat up, causing the air in the rear cavity 3 to expand and the pressure to increase. The expanded gas in the rear cavity 3 enters the inner ring of the speaker bracket 8, and then flows from the air circulation area 14 of the concave diaphragm 12 to the core-pore membrane waterproof and breathable sound-generating dome 6. Because the core-pore membrane waterproof and breathable sound-generating dome 6 is made of a core-pore membrane, it will be discharged through the core micropores 9 of the core-pore membrane waterproof and breathable sound-generating dome 6, realizing automatic pressure relief, eliminating the gas pressure generated by the heat of the machine, protecting the normal working balance of the speaker vibration system, and keeping the rear cavity 3 of the housing consistent with the external atmospheric pressure in real time, without changing the original electroacoustic characteristics of the speaker.

[0043] (2) The nuclear pore membrane fabrication process consists of two steps:

[0044] The first step involves using a large nuclear facility to accelerate atomic nuclei to extremely high energies and bombard a plastic film of a certain thickness. When the etchable range of heavily charged particles in the insulating film exceeds the film thickness, the radiation damage generated along the path of each vertically incident heavily charged particle has a diameter of approximately several nanometers. A film with such radiation damage can be understood as having numerous pores of several nanometers on its surface. The second step involves etching the aforementioned radiation-damaged film, transforming the radiation-damaged channels into through-hole nuclear micropores. By controlling the irradiation and etching conditions, nuclear-pore films with different pore densities and diameters can be obtained.

[0045] Nuclear pore membranes exhibit excellent rigidity and temperature performance. They possess four main characteristics: First, controllable pore density, ranging from one pore per square centimeter to 10 billion pores; second, uniform pore size, with all pores having the same diameter because atomic nuclei accelerate with a single energy and a single mass, resulting in identical pore sizes; third, a very wide and precisely controllable pore size range, from a few nanometers to tens of micrometers, spanning four orders of magnitude invisible to the naked eye; fourth, deep waterproofing and breathability; and fifth, high mechanical strength, good toughness, and a smooth surface with no fiber shedding.

[0046] Further, in this embodiment, as Figures 1 to 16 shown, we upgraded the thickness of the nuclear pore membrane waterproof and breathable sound dome 6 made of nuclear pore membrane to a certain thickness, which has both a certain rigidity and a waterproof and breathable function. The nuclear pore membrane waterproof and breathable sound dome 6 of the self-relieving waterproof speaker is made and applied to the self-relieving waterproof speaker to make a self-relieving waterproof speaker with a nuclear pore membrane waterproof and breathable sound dome. For self-relieving waterproof speakers with a power of less than 0.5W, the thickness of the nuclear pore membrane waterproof and breathable sound dome 6 is usually above 12μm. For self-relieving waterproof speakers with a power greater than 0.5W, the thickness of the nuclear pore membrane waterproof and breathable sound dome 6 is usually above 50μm. The nuclear pore membrane waterproof and breathable sound dome 6 has an oil-repellent and water-repellent layer 15, and the oil-repellent and water-repellent layer 15 is located above or below or both above and below the nuclear pore membrane waterproof and breathable sound dome 6.

[0047] Further, in this embodiment, as Figures 1 to 16 shown, the nuclear pore membrane waterproof and breathable sound dome 6 is composed of one layer or multiple layers of nuclear pore membrane. That is, the nuclear pore membrane waterproof and breathable sound dome 6 can be composed of only a single layer of nuclear pore membrane or multiple layers of nuclear pore membrane.

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

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

[0050] Among them, the English full name of PEI is Polyetherimide, and the Chinese name is polyetherimide;

[0051] The English full name of PEN is Polyethylene Naphthalate, and the Chinese name is polyethylene naphthalate;

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

[0053] The English full name of PI is PolyimideFilm, and the Chinese name is polyimide film;

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

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

[0056] In this embodiment, as Figures 1 to 16As shown, the nuclear pore membrane waterproof, breathable, and sound-emitting dome 6 can be a planar sheet structure, a convex sheet structure, or a concave sheet structure. A planar sheet structure means that the entire nuclear pore membrane waterproof, breathable, and sound-emitting dome 6 is a planar membrane. (Refer to...) Figures 1 to 11 The convex plate structure is a planar structure with the center convex upwards, see reference. Figures 12 to 13 The concave sheet structure is a planar structure with a downward convex center, see reference. Figure 14 .

[0057] Furthermore, in this embodiment, as Figures 1 to 16 As shown, patterns or designs can also be applied to the waterproof and breathable sound-emitting dome 6 of the core pore membrane to meet the functional requirements of enhancing the mid-to-high frequency characteristics of the loudspeaker.

[0058] Furthermore, in this embodiment, as Figures 1 to 16 As shown, the waterproof, breathable, and sound-generating dome 6 of the core-pore membrane is fixedly connected to the air circulation area by bonding, welding, or wrapping. If the embedding method is injection molding wrapping, that is, when injection molding the concave vibrating membrane 12, the edge of the waterproof, breathable, and sound-generating dome 6 of the core-pore membrane is wrapped inside.

[0059] In this embodiment, as Figures 1 to 16 As shown, when the concave diaphragm 12 is fixedly connected to the speaker coil 11, the positional relationship between the concave diaphragm 12, the speaker coil 11, and the waterproof and breathable sound-generating dome 6 is divided into two types: one is that the concave diaphragm 12 is located between the speaker coil 11 and the waterproof and breathable sound-generating dome 6, such as... Figure 1 , Figure 2 , Figure 6 , Figure 7 As shown, one type involves a concave diaphragm 12 and a waterproof and breathable sound-generating dome 6 located simultaneously on one side of the speaker coil 11, such as... Figure 6 As shown.

[0060] When the waterproof and breathable sound-generating dome 6 of the nuclear pore membrane is fixedly connected to the speaker coil 11, the waterproof and breathable sound-generating dome 6 of the nuclear pore membrane is located between the speaker coil 11 and the concave diaphragm 12, such as Figure 8 As shown.

[0061] In this embodiment, as Figures 1 to 16 As shown, both the speaker cover 7 and the speaker bracket 8 are ring-shaped structures, which can be circular, rectangular, elliptical, etc., and irregular shapes can also be used; no further restrictions are placed here. The speaker magnetic circuit 10 is located within the inner ring of the speaker bracket 8, and the sound-emitting dome 6 is located within the inner ring of the speaker cover 7.

[0062] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
