Description

Technical Field

[0001] The present invention relates to the technical field of earphones, and more specifically, to an earphone housing and a wearable device based on dynamic silicone fitting. Background Art

[0002] Silicone is a high-molecular elastic material with a silicon-oxygen bond as the main chain structure. It combines the stability of inorganic materials and the flexibility of organic materials. At the same time, it has stable chemical properties, is resistant to high and low temperatures, aging, non-toxic and odorless, and has excellent insulation, air permeability and biocompatibility, and is widely used in medical, food, electronics and other fields. In the design of earphone housings, silicone materials have become an important choice due to their unique properties. As an electronic product worn close to the body, earphones have high requirements for comfort and durability. Silicone has a soft contact touch, and its high damping characteristics can effectively absorb external vibration and collision energy to protect the internal precision components. In addition, the sealing property of silicone can enhance the passive noise reduction effect of earphones, reduce sound leakage, and block the intrusion of sweat and dust, extending the service life. At the process level, liquid silicone can achieve complex cavity structures through injection molding, and combined with two-color injection molding technology, it can also be compounded with hard plastics or metal frames to balance structural strength and wearing experience.

[0003] Although silicone materials have shown many advantages in the application of earphone housings, they still have significant limitations in adapting to fit different auricle shapes. The elastic modulus of silicone is fixed. Although it can provide a basic fit through prefabricated geometric shapes, in the face of the diversity of the user's auricle structure, such as differences in ear canal width, bending angle, soft tissue thickness, etc., it is difficult to achieve dynamic adaptation, resulting in problems such as insufficient sealing, poor wearing stability or obvious pressure sensation, further leading to fluctuations in noise reduction effect or discomfort during long-term use. In addition, the deformation recovery characteristic of silicone makes it possible to produce a fitting feeling due to extrusion at the initial stage of wearing, but with the user's head movement or slight changes in the ear canal muscles, such as chewing and speaking, the material cannot adjust its shape in real time to maintain close contact, and it is easy to have sound leakage or looseness.

[0004] In view of this, the present invention provides an earphone housing and a wearable device based on dynamic silicone fitting. The present invention adopts a double-air cavity structure of a silicone-based airbag cooperating with a cavity, and uses the extrusion deformation effect of the silicone airbag combined with the relationship between airbag deformation and gas pressure to control the gas flow in the airbag, so as to further realize the regulation of the airbag pressure.

[0005] The information disclosed in this background art section is only for increasing the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that this information constitutes the prior art already known to those of ordinary skill in the art. Summary of the Invention

[0006] To solve the above technical problems, the object of the present invention is to provide an earphone housing and a wearable device based on dynamic silicone fitting. The present invention adopts a double-air chamber structure of a silicone airbag cooperating with a cavity, and utilizes the extrusion deformation effect of the silicone airbag and the relationship between the airbag deformation and the gas pressure. When the user wears the earphone, based on the pressure deformation generated on the airbag during the wearing process, the gas pressure inside the airbag is further affected, and the gas flow inside the airbag is controlled to further adjust the airbag pressure.

[0007] To achieve the above object, on the one hand, the present invention provides an earphone housing. In the technical solution of the present invention, the earphone housing includes a silicone ear support for contacting the user's auricle when wearing the earphone and an earphone main body housing for installing earphone electronic components. The silicone ear support includes at least one airbag. The silicone ear support contacts the user's auricle through the airbag, and the contact surface between the airbag and the user's auricle is made of silicone. At least one cavity is arranged on one side of the airbag; there are two through holes between the cavity and the airbag, and the internal gases of the cavity and the airbag communicate with each other through the through holes; adjustable pressure valves and reset valves are respectively arranged at the two through holes and are both in a closed state. When wearing the silicone ear support, the airbag fits the user's auricle, and the user's auricle squeezes the airbag to cause it to deform, resulting in an increase in the air pressure inside the airbag. When the air pressure inside the airbag increases beyond the threshold of the adjustable pressure valve, the gas in the airbag pushes open the adjustable pressure valve and enters the cavity. Press the reset valve to open the through hole at the reset valve to facilitate the air pressure in the airbag and the cavity to return to balance.

[0008] Further, in the technical solution of the present invention, the silicone ear support is annular, the silicone ear support is snap-fitted on the outside of the earphone main body housing, a snap-fitting hole is arranged on the inner side of the silicone ear support, and a snap-fitting block is arranged on the outside of the earphone main body housing.

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

[0010] Further, in the technical solution of the present invention, the adjustable pressure valve includes a first sealing piece, a first sliding rod, a pressure spring and a rotation adjustment shaft. The first sealing piece is used to seal the through hole at the adjustable pressure valve, and one end of the first sealing piece is fixedly connected with the first sliding rod; the pressure spring is sleeved outside the first sliding rod and is used to apply pressure to the first sealing piece; a sliding hole is opened inside one end of the rotation adjustment shaft, and the rotation adjustment shaft is slidably arranged outside the first sliding rod and squeezes the pressure spring. The other end of the rotation adjustment shaft is provided with threads outside and extends out of the cavity through the threaded hole.

[0011] Further, in the technical solution of the present invention, the reset valve includes a second sealing piece, a second sliding rod, a pressing head and a pressing spring. The second sealing piece is used to close the through hole at the reset valve. One end of the second sealing piece is fixedly connected to a second sliding rod; the other end of the second sliding rod extends into the sliding cavity through the moving hole, and the pressing head is fixedly installed at one end of the second sliding 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 outside the second sliding rod, and both ends of the pressing spring respectively contact one end of the sliding cavity and one end of the pressing head to apply a pressing pressure.

[0012] Further, on the other hand, the present invention also provides a wearable device, which adopts an earphone housing as described above and further includes an earphone main body.

[0013] Effective gain: In summary, the present invention provides an earphone housing and a wearable device based on dynamic silicone fitting. The present invention adopts a double-air cavity structure of a silicone-based airbag cooperating with a cavity, and at the same time utilizes the extrusion deformation effect of the silicone airbag and combines the relationship between the deformation of the airbag and the gas pressure inside it. When the user wears it, based on the pressure deformation generated on the airbag during the wearing process, the gas pressure inside the airbag is affected. In addition, the present invention provides a pressure-adjustable valve and a reset valve in the airbag and the cavity. When the gas pressure inside the airbag increases and exceeds the threshold value of the pressure-adjustable valve, the gas inside the airbag pushes open the pressure-adjustable valve and enters the cavity, realizing the adjustment of the air pressure inside the airbag, further optimizing the acting pressure generated by the airbag on the user's auricle when the user wears it, and at the same time pressing the reset valve can make the air pressures in the airbag and the cavity return to balance.

Specific embodiments

[0017] To make the objectives, features, and advantages of the present invention more obvious and understandable, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the embodiments described below are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0018] The core of the embodiments of the present invention is to provide a headphone housing and a wearable device based on dynamic silicone fitting. The embodiments of the present invention adopt a double-air cavity structure of a silicone airbag cooperating with a cavity, utilize the extrusion deformation effect of the silicone airbag, combine the relationship between the airbag deformation and the gas pressure, and based on the pressure deformation generated on the airbag during the user's wearing process, further affect the gas pressure in the airbag, and control the gas flow in the airbag to further adjust the airbag pressure.

[0019] On the one hand, the embodiments of the present invention propose a headphone housing. In this embodiment, Figure 1 and Figure 2 are the overall structural schematic diagrams of a headphone housing in the embodiments of the present invention. As shown in Figure 1 and Figure 2 the headphone housing of this embodiment includes a silicone ear support A for contacting the user's auricle during headphone wearing and a headphone main body housing B for installing headphone electronic components. The silicone ear support A includes at least one airbag A01. When the user wears the headphones, the worn silicone ear support A contacts the user's auricle through the airbag A01, and the contact surface between the airbag A01 and the user's auricle is made of silicone material. At least one cavity A02 is arranged on one side of the airbag A01;Figure 3 This is a schematic cross-sectional view of a partial structure of an earphone housing according to an embodiment of the present invention. Figure 4 For Figure 3 the enlarged view of the structure of part of area X in Figure 3 and Figure 4 As shown, there are two through holes A03 between the cavity A02 and the airbag A01, and the internal gases of the cavity A02 and the airbag A01 can flow through each other via the through holes A03; an adjustable pressure valve C and a reset valve D are respectively provided at the two through holes A03, and the adjustable pressure valve C and the reset valve D are both in a closed state under normal conditions. When the user wears the silicone earplug A, the airbag A01 fits against the user's auricle. During the wearing process, the user's auricle will squeeze the airbag A01, causing it to deform and increasing the air pressure inside the airbag A01. When the air pressure inside the airbag A01 increases beyond the threshold of the adjustable pressure valve C, the gas inside the airbag A01 squeezes open the adjustable pressure valve C and enters the cavity A02. Press the reset valve D to open the through hole A03 at the reset valve D so that the air pressures in the airbag A01 and the cavity A02 can return to balance again. It should be noted that in the face of the diversity of the user's auricle structure, such as differences in the width and narrowness of the ear canal, the bending angle, the thickness of soft tissues, etc., the degree of squeezing and deformation of the airbag A01 by the user's auricle resulting in an increase in the air pressure inside the airbag A01 varies. The threshold of the adjustable pressure valve C is set within the static pressure bearing range of the user's auricle, usually 50 - 100 mN / cm 2 , and the upper pressure limit can be adjusted according to the specific feelings of the user. That is, when the squeezing deformation of the airbag A01 by the user's auricle causes the internal air pressure to increase to the upper limit of the static pressure bearing of the user's auricle, the gas inside the airbag A01 can squeeze open the adjustable pressure valve C and enter the cavity A02 to adjust the air pressure of the airbag A01. Further, the pressure brought by the airbag A01 to the user's auricle is also adjusted. And after adjusting the upper pressure limit according to the specific feelings of the user, that is, the threshold of the adjustable pressure valve C, the subsequent user wearing and the pressure adjustment of the airbag A01 are both self-adaptive dynamic adjustment processes.

[0020] Specifically, please continue to refer to Figure 2 , in this embodiment, the silicone earplug A is annular, the silicone earplug A is snap-fitted on the outside of the earphone main body housing B, a snap-fitting hole A04 is provided on the inner side of the silicone earplug A, and a snap-fitting block B01 is provided on the outside of the earphone main body housing B. When the silicone earplug A and the earphone main body housing B are snap-fitted, the snap-fitting block B01 is snap-fitted into the snap-fitting hole A04.

[0021] Specifically, Figure 5 For Figure 3 the enlarged view of the structure of part of area X in Figure 4 and Figure 5, the cavity A02 is also provided with a threaded hole A02-1 and a sliding opening A02-2, and the sliding opening A02-2 includes a movable hole A02-21 and a sliding cavity A02-22.

[0022] Specifically, please continue to refer to Figure 4 , in this embodiment, the pressure adjustable valve C includes a first sealing piece C01, a first sliding rod C02, a pressure spring C03 and a rotating adjustment shaft C04; the first sealing piece C01 is used to seal the through hole A03 at the pressure adjustable valve C, and one end of the first sealing piece C01 is fixedly connected with a first sliding rod C02; the pressure spring C03 is sleeved outside the first sliding rod C02, and the pressure spring C03 is used to apply pressure to the first sealing piece C01; a sliding hole (not shown in the figure) is opened inside one end of the rotating adjustment shaft C04, and it is slidably arranged outside the first sliding rod C02 and squeezes the pressure spring C03 (for the specific implementation of this embodiment, please refer to Figure 4 ), the other end of the rotating adjustment shaft C04 is externally provided with threads and extends out of the cavity A02 through the threaded hole A02-1. It should be noted that the threshold adjustment of the pressure adjustable valve C is achieved by controlling the compression elastic force of the pressure spring C03, that is, by rotating the rotating adjustment shaft C04, making the rotating adjustment shaft C04 move into the cavity A02 along the threaded hole A02-1 to further compress the pressure spring C03 and increase the compression elastic force of the pressure spring C03. On the contrary, making the rotating adjustment shaft C04 move out of the cavity A02 along the threaded hole A02-1 can gradually loosen the compression of the pressure spring C03 and reduce the compression elastic force of the pressure spring C03. According to the elastic coefficient and compression distance of the pressure spring C03, the pressure magnitude of the pressure spring C03 can be obtained, and further the threshold magnitude of the pressure adjustable valve C can be obtained.

[0023] Specifically, please continue to refer to Figure 5 , in this embodiment, the reset valve D includes a second sealing piece D01, a second sliding rod D02, a pressing head D03 and a pressing spring D04; the second sealing piece D01 is used to seal the through hole A03 at the reset valve D, and one end of the second sealing piece D01 is fixedly connected with a 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, and 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 the specific implementation of this embodiment, please refer to Figure 5); The pressing spring D04 is located within the sliding cavity A02-22 and is sleeved outside the second sliding rod D02. Both ends of the pressing spring D04 respectively contact one end of the sliding cavity A02-22 and one end of the pressing head D03 to apply pressing pressure. It should be noted that pressing the reset valve D opens the through hole A03 at the reset valve D to facilitate the air pressure in the airbag A01 and the cavity A02 to restore balance again. Specifically, it includes pressing the pressing head D03, driving the second sealing piece D01 at the other end of the second sliding rod D02 to displace inward through the pressing head D03 and the second sliding rod D02, that is, away from the through hole A03. 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, driving the second sealing piece D01 at the other end of the second sliding rod D02 back to the through hole A03.

[0024] On the other hand, this embodiment also provides a wearable device. Figure 6 As shown in the structural schematic diagram of a wearable device according to an embodiment of the present invention.
