Description

Technical Field

[0001] This invention relates to the field of headphone technology, and more specifically, to a headphone shell and wearable device based on silicone dynamic bonding. Background Technology

[0002] Silicone is a high-molecular-weight elastic material with a silicon-oxygen bond main chain structure, combining the stability of inorganic materials with the flexibility of organic materials. It is also chemically stable, resistant to high and low temperatures, aging, non-toxic, odorless, and possesses excellent insulation, breathability, and biocompatibility, making it widely used in medical, food, and electronics fields. In headphone shell design, silicone is a crucial material due to its unique properties. Headphones, as close-fitting electronic products, require high levels of comfort and durability. Silicone offers a soft touch, and its high damping properties effectively absorb external vibrations and impact energy, protecting delicate internal components. Furthermore, silicone's sealing properties enhance passive noise cancellation, reduce sound leakage, and prevent sweat and dust intrusion, extending the lifespan of the headphones. In terms of manufacturing, liquid silicone can be injection molded to create complex cavity structures. Combined with two-color injection molding technology, it can also be laminated with rigid plastics or metal frames, balancing structural strength and wearing comfort.

[0003] While silicone materials offer numerous advantages in headphone housings, they still have significant limitations in adapting to different ear shapes. Silicone's fixed elastic modulus, while providing a basic fit through pre-formed geometry, struggles to dynamically adapt to the diverse ear structures of users, such as ear canal width, curvature, and soft tissue thickness. This leads to insufficient sealing, poor wearing stability, or noticeable pressure, further causing fluctuations in noise cancellation or discomfort during prolonged use. Furthermore, silicone's deformation recovery properties may initially create a snug fit due to compression, but with subtle changes in head movement or ear canal muscles, such as chewing or speaking, the material cannot adjust its shape in real time to maintain a tight contact, easily resulting in sound leakage or loosening.

[0004] In view of this, the present invention provides an earphone shell and wearable device based on silicone dynamic bonding. The present invention adopts a dual-cavity structure with an airbag and cavity based on silicone material. By utilizing the compression deformation effect of the silicone airbag and the relationship between airbag deformation and gas pressure, the gas flow in the airbag is controlled to further regulate the airbag pressure.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0006] To address the aforementioned technical problems, the present invention aims to provide an earphone shell and wearable device based on silicone dynamic bonding. The present invention employs a dual-cavity structure with an airbag and cavity based on silicone material. By utilizing the compression deformation effect of the silicone airbag and the relationship between airbag deformation and gas pressure, the pressure deformation generated on the airbag during wear affects the gas pressure inside the airbag. By controlling the gas flow inside the airbag, the airbag pressure can be further regulated.

[0007] To achieve the above objectives, the present invention provides an earphone shell. In this invention, the earphone shell includes a silicone ear support for contacting the user's ear when the earphone is worn, and an earphone body shell for housing earphone electronic components. The silicone ear support includes at least one air bladder. The silicone ear support contacts the user's ear through the air bladder, and the contact surface between the air bladder and the user's ear is made of silicone. At least one cavity is disposed on one side of the air bladder. Two through holes are provided between the cavity and the air bladder, allowing gas to circulate between the cavity and the air bladder. An adjustable pressure valve and a reset valve are respectively provided at the two through holes, both of which are in a closed state. When the silicone ear support is worn, the air bladder conforms to the user's ear, and the user's ear compresses the air bladder, causing it to deform and increasing the internal air pressure. When the internal air pressure exceeds the threshold of the adjustable pressure valve, the gas in the air bladder forces open the adjustable pressure valve and enters the cavity. Pressing the reset valve opens the through hole at the reset valve to restore the air pressure balance between the air bladder and the cavity.

[0008] Furthermore, in the technical solution of the present invention, the silicone ear support is annular, the silicone ear support is snapped onto the outside of the earphone body shell, the inner side of the silicone ear support is provided with a snap-fit ​​hole, and the outside of the earphone body shell is provided with a snap-fit ​​block.

[0009] Furthermore, in the technical solution of the present invention, the cavity is also provided with a threaded hole and a sliding opening, the sliding opening including a movable hole and a sliding cavity.

[0010] Furthermore, in the technical solution of the present invention, the adjustable pressure valve includes a first sealing plate, a first slide rod, a pressure spring, and a rotating adjusting shaft. The first sealing plate is used to close the through hole at the adjustable pressure valve. One end of the first sealing plate is fixedly connected to the first slide rod. The pressure spring is sleeved on the outside of the first slide rod and is used to apply pressure to the first sealing plate. One end of the rotating adjusting shaft has a sliding hole inside and is slidably disposed outside the first slide rod to compress the pressure spring. The other end of the rotating adjusting shaft has a thread on the outside and extends out of the cavity through the threaded hole.

[0011] Furthermore, in the technical solution of the present invention, the reset valve includes a second sealing plate, a second slide rod, a pressing head, and a pressing spring. The second sealing plate is used to close the through hole at the reset valve. One end of the second sealing plate is fixedly connected to the second slide rod. The other end of the second slide rod extends into the sliding cavity through the movable hole. The pressing head is fixedly installed at one end of the second slide rod located in the sliding cavity and extends out of the cavity along the sliding cavity. The pressing spring is located in the sliding cavity and sleeved on the outside of the second slide rod. The two ends of the pressing spring respectively contact one end of the sliding cavity and one end of the pressing head to apply pressing pressure.

[0012] Furthermore, another aspect of the present invention provides a wearable device that employs an earphone shell as described above and also includes an earphone body.

[0013] Effective Gain: In summary, this invention provides an earphone shell and wearable device based on silicone dynamic bonding. The invention employs a dual-cavity structure with a silicone-based airbag and cavity. It utilizes the compression deformation effect of the silicone airbag, combined with the relationship between airbag deformation and internal gas pressure. During wear, the pressure deformation of the airbag affects the gas pressure within it. Furthermore, the invention incorporates adjustable pressure valves and reset valves in the airbag and cavity. When the gas pressure inside the airbag exceeds the threshold of the adjustable pressure valve, the gas inside the airbag forces open the valve and enters the cavity, thus regulating the internal air pressure. This further optimizes the pressure exerted by the airbag on the user's ear during wear. Simultaneously, pressing the reset valve restores the pressure balance between the airbag and cavity.

Detailed Implementation

[0023] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0024] The core of this invention is to provide an earphone shell and wearable device based on silicone dynamic bonding. This invention adopts a dual-cavity structure with an airbag and cavity based on silicone material. By utilizing the compression deformation effect of the silicone airbag and the relationship between airbag deformation and gas pressure, the pressure deformation generated on the airbag during wear affects the gas pressure inside the airbag. By controlling the gas flow inside the airbag, the airbag pressure can be further regulated.

[0025] One embodiment of the present invention provides an earphone shell. In this embodiment, Figure 1 and Figure 2 This is a schematic diagram of the overall structure of an earphone shell according to an embodiment of the present invention, as shown below. Figure 1 and Figure 2As shown, the earphone shell of this embodiment includes a silicone ear support A for contacting the user's auricle when the earphone is worn, and an earphone body shell B for mounting the earphone electronic components. The silicone ear support A includes at least one air bladder A01. When the user wears the earphone, the silicone ear support A contacts the user's auricle through the air bladder A01, and the contact surface between the air bladder A01 and the user's auricle is made of silicone material. At least one cavity A02 is disposed on one side of the air bladder A01. Figure 3 This is a partial cross-sectional schematic diagram of an earphone shell according to an embodiment of the present invention. Figure 4 To Figure 3 Enlarged view of the structure of region X in the middle area, as shown below. Figure 3 and Figure 4 As shown, two through holes A03 are provided between the cavity A02 and the airbag A01, allowing the internal gas of the cavity A02 and the airbag A01 to circulate between them. An adjustable pressure valve C and a reset valve D are respectively located at the two through holes A03, and both valves are normally closed. When the user wears the silicone ear support A, the airbag A01 conforms to the user's ear. During wear, the user's ear compresses the airbag A01, causing it to deform and increasing the internal air pressure. When the internal air pressure of the airbag A01 exceeds the threshold of the adjustable pressure valve C, the airbag... The gas inside A01 forces open the adjustable pressure valve C and enters the cavity A02. Pressing the reset valve D opens the through-hole A03 at the reset valve D, allowing the air pressure inside the airbag A01 and the cavity A02 to return to equilibrium. It should be noted that, given the diversity of users' auricular structures, such as differences in ear canal width, curvature angle, and soft tissue thickness, the degree to which the user's auricle compresses and deforms the airbag A01, leading to an increase in internal air pressure, varies. The threshold of the adjustable pressure valve C is set within the static pressure tolerance range of the user's auricle, typically 50-100 mN / cm². 2 The pressure limit can be adjusted according to the user's specific experience. When the user's auricle compresses and deforms the airbag A01, causing the internal air pressure to increase to the static pressure limit that the user's auricle can withstand, the gas in the airbag A01 can open the adjustable pressure valve C and enter the cavity A02 to regulate the air pressure of the airbag A01. This further regulates the pressure that the airbag A01 exerts on the user's auricle. After adjusting the pressure limit according to the user's specific experience, i.e., the threshold of the adjustable pressure valve C, the subsequent user wearing and the pressure adjustment of the airbag A01 are all adaptive dynamic adjustment processes.

[0026] For details, please continue reading. Figure 2 In this embodiment, the silicone ear support A is ring-shaped and is snapped onto the outside of the earphone body shell B. The inner side of the silicone ear support A is provided with a snap-fit ​​hole A04, and the outside of the earphone body shell B is provided with a snap-fit ​​block B01. When the silicone ear support A and the earphone body shell B are snapped together, they are snapped into the snap-fit ​​hole A04 by the snap-fit ​​block B01.

[0027] Specifically, Figure 5 To Figure 3 Please refer to the enlarged structural diagram of section X in the central region. Figure 4 and Figure 5 The cavity A02 is also provided with a threaded hole A02-1 and a sliding opening A02-2. The sliding opening A02-2 includes a movable hole A02-21 and a sliding cavity A02-22.

[0028] For details, please continue reading. Figure 4 In this embodiment, the adjustable pressure valve C includes a first sealing plate C01, a first slide rod C02, a pressure spring C03, and a rotating adjustment shaft C04. The first sealing plate C01 is used to close the through hole A03 at the adjustable pressure valve C, and one end of the first sealing plate C01 is fixedly connected to the first slide rod C02. The pressure spring C03 is sleeved on the outside of the first slide rod C02 and is used to apply pressure to the first sealing plate C01. One end of the rotating adjustment shaft C04 has a sliding hole (not shown in the figure) inside, and is slidably disposed outside the first slide rod C02 and compresses the pressure spring C03 (for specific implementation of this embodiment, please refer to [reference needed]). Figure 4 The other end of the rotating adjustment shaft C04 is threaded and extends out of the cavity A02 through the threaded hole A02-1. It should be noted that the threshold adjustment of the adjustable pressure valve C is achieved by controlling the compression force of the pressure spring C03. That is, by rotating the rotating adjustment shaft C04, the rotating adjustment shaft C04 moves into the cavity A02 along the threaded hole A02-1 to further compress the pressure spring C03 and increase the compression force of the pressure spring C03. Conversely, by moving the rotating adjustment shaft C04 out of the cavity A02 along the threaded hole A02-1, the compression of the pressure spring C03 can be gradually released and the compression force of the pressure spring C03 can be reduced. According to the spring force coefficient and compression distance of the pressure spring C03, the pressure of the pressure spring C03 can be obtained, and the threshold value of the adjustable pressure valve C can be obtained.

[0029] For details, please continue reading. Figure 5 In this embodiment, the reset valve D includes a second sealing plate D01, a second sliding rod D02, a pressing head D03, and a pressing spring D04. The second sealing plate D01 is used to close the through hole A03 at the reset valve D. One end of the second sealing plate D01 is fixedly connected to the second sliding rod D02. The other end of the second sliding rod D02 extends into the sliding cavity A02-22 through the movable hole A02-21. The pressing head D03 is fixedly installed at one end of the second sliding rod D02 located in the sliding cavity A02-22 and extends out of the cavity A02 along the sliding cavity A02-22 (for specific implementation of this embodiment, please refer to...). Figure 5The pressing spring D04 is located inside the sliding cavity A02-22 and sleeved outside the second slide rod D02. The two ends of the pressing spring D04 contact one end of the sliding cavity A02-22 and one end of the pressing head D03 respectively to apply pressing pressure. It should be noted that pressing the reset valve D opens the through hole A03 at the reset valve D so that the air pressure in the airbag A01 and the cavity A02 can be restored to balance. Specifically, pressing the pressing head D03 causes the second sealing plate D01 at the other end of the second slide rod D02 to move inward, that is, away from the through hole A03, through the pressing head D03 and the second slide rod D02. When the pressing head D03 is released, under the action of the pressing spring D04, the pressing head D03 moves outward along the sliding cavity A02-22, causing the second sealing plate D01 at the other end of the second slide rod D02 to return to the through hole A03.
