Description

Technical Field

[0001] This application relates to the field of electronic device technology, and in particular to a pair of headphones. Background Technology

[0002] Wireless headphones are popular among users due to their portability and ease of use. With the maturity of related technologies and the reduction in costs, the market share of wireless headphones is gradually increasing, and they are showing a strong trend of replacing traditional wired headphones.

[0003] Although wireless headphones have been widely used and accepted, it has been found that when users run, jump, or tap the wireless headphones while wearing them, the headphones may easily fall out of their ears. Summary of the Invention

[0004] The earphones provided in this application can effectively reduce the chance of them falling out of the user's ears during wear, and have the advantage of being easy to remove from the ears after use.

[0005] This application provides an earphone, wherein the earphone comprises:

[0006] Ear caps;

[0007] Deformation member, mounted on the inner surface of the ear cap;

[0008] When energized, the deformation member causes the ear cap to expand or contract; when de-energized, the shape of the deformation member remains unchanged.

[0009] In the earphone described above, the deformation member is made of carbon fiber composite material. When a positive voltage is applied to the deformation member, the deformation member can deform in a direction away from the central axis of the ear cap and cause the ear cap to expand. When a negative voltage is applied to the deformation member, the deformation member can deform in a direction closer to the central axis of the ear cap and cause the ear cap to contract.

[0010] As described above, the deformable component includes a first carbon fiber layer, an electrolyte membrane layer, and a second carbon fiber layer. The first carbon fiber layer is fixedly connected to the inner surface of the ear cap. The second carbon fiber layer is located on the side of the first carbon fiber layer near the central axis of the ear cap. The electrolyte membrane layer is fixedly connected between the first carbon fiber layer and the second carbon fiber layer. Both the first carbon fiber layer and the second carbon fiber layer are doped with lithium ions.

[0011] In the earphone described above, the deformable member has a strip-shaped structure and is provided in multiples, with the multiple deformable members spaced apart circumferentially along the ear cap.

[0012] In the earphone described above, the deformable member has a ring structure and is provided in multiple forms, with the multiple deformable members spaced apart along the extension direction of the central axis of the ear cap.

[0013] In the earphone described above, the deformable component has a mesh structure and is evenly distributed on the inner surface of the ear cap.

[0014] As described above, the deformable component includes a plurality of first deformable elements and a plurality of second deformable elements. The first deformable elements are strip-shaped and are provided in multiples. The plurality of first deformable elements are spaced apart along the circumference of the ear cap. The second deformable elements are strip-shaped and are provided in multiples. The plurality of second deformable elements are spaced apart along the circumference of the ear cap. The first deformable elements and the second deformable elements are intersected and connected to form the mesh structure.

[0015] The headphones described above further include a body, and the ear tips are detachably mounted on the body.

[0016] The headphones described above, wherein the headphones further include:

[0017] A first detection and control element is disposed on the ear cap and electrically connected to the deformation member. The first detection and control element is used to detect the first pressure applied to the ear cap.

[0018] A second detection and control element is disposed on the body and electrically connected to the deformation member. The second detection and control element is used to detect the second pressure applied to the body.

[0019] When the first pressure is greater than or equal to the first threshold and the second pressure is less than the second threshold, the deformation member can deform in a direction away from the central axis of the ear cap and cause the ear cap to expand; when the second pressure is greater than the second threshold, the deformation member can deform in a direction closer to the central axis of the ear cap to cause the ear cap to contract; when the first pressure is less than the first threshold and the second pressure is equal to the second threshold, the ear cap is in its initial state.

[0020] The headphones described above, wherein the first threshold is greater than 0N, and the second threshold is greater than or equal to 0N.

[0021] The earphones provided in this application, when the ear caps are inserted into the user's ear, can expand by applying power, causing the deformation element to drive the ear caps to expand, thereby increasing the friction between the ear caps and the user's ear. After power is off, the earphones maintain their deformed state, ensuring that the ear caps are tightly fitted and positioned against the user's ear. When the earphones need to be removed after use, applying power can cause the deformation element to drive the ear caps to contract, thereby reducing the friction between the ear caps and the user's ear, making it easier to remove them from the user's ear.

[0046] The embodiments of this application will now be described in detail. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0047] With the advent of the 5G and IoT era, the functions of intelligent products are increasingly surprising the public. True Wireless Stereo (TWS) earphones, due to their portability, ease of use, and stylish design, have become a market trend and are widely welcomed. As related technologies mature and costs decrease, the market share of TWS earphones is gradually increasing, showing a strong trend of replacing traditional wired earphones.

[0048] Despite the widespread use and acceptance of TWS earbuds, challenges and drawbacks still exist in their use. For example, users often experience the earbuds falling out of their ears while participating in various activities such as exercise or running. Although various molding designs and protruding anchors have been developed to address this issue, many users still experience the earbuds falling out during activities. This challenge is even greater with larger and heavier wireless earbuds, making them more prone to falling out of the user's ears.

[0049] In addition, many of these wireless headphones include one or more user interface features, such as requiring the user to tap the headphones, which could also cause the headphones to fall out of the user's ears.

[0050] To address the issue of earphones falling out of users' ears, neckband headphones, headphones combining neckband and ear hooks, and ear hook wireless headphones have emerged on the market. Compared to TWS earphones, they all have shortcomings:

[0051] ① Neckband headphones: These require a connection structure between the headphones and the neckband, which is complex and inconvenient to carry.

[0052] ② Neckband and ear hook combination headphones: These require ear hooks and connecting cables, making them complex and inconvenient to carry.

[0053] ③ Ear-hook wireless earphones: The structure is relatively simple, but compared with TWS earphones, an additional ear-hook structure is required.

[0054] In view of the problems existing in the above-mentioned related technologies, this application provides an earphone that can automatically adjust the size of its ear tips according to its usage status, so as to improve the tightness between the ear tips and the user's ears, thereby effectively reducing the situation where the earphones fall out of the user's ears unnecessarily and improving the user experience.

[0055] like Figures 1 to 5 As shown, this application provides an earphone, which includes an ear cap 1 and a deformable component 2. The ear cap 1 is made of a material with good elastic deformation ability, such as rubber or silicone, so that it can deform according to the shape of the user's ear during use, thereby ensuring a tight fit between the ear cap 1 and the user's ear.

[0056] The ear cap 1 is an arc-shaped shell structure with an opening on one side for assembly with other parts of the earphone. The ear cap 1 has a central axis extending along the through direction of the opening.

[0057] The deformation component 2 is installed on the inner surface of the ear cap 1. The deformation component 2 can deform and drive the ear cap 1 to elastically deform in order to adjust the tightness of the fit between the ear cap 1 and the user's ear.

[0058] When powered on, the deformation member 2 can deform away from the central axis of the ear cap 1 and cause the ear cap 1 to expand, thereby increasing the friction between the ear cap 1 and the user's ear. After power is off, the deformation member 2 can maintain its deformed state, so that the ear cap 1 is tightly abutted and positioned against the user's ear. When the earphone needs to be removed after use, when powered on, the deformation member 2 can deform towards the central axis of the ear cap 1 to cause the ear cap 1 to contract, thereby reducing the friction between the ear cap 1 and the user's ear, so that it can be easily removed from the user's ear.

[0059] When the power is off, the shape of the deformation component 2 remains unchanged, which can effectively reduce the power consumption of the deformation component 2 during the deformation process and reduce the overall cost of the deformation component 2 and the headphones.

[0060] like Figures 6 to 10 As shown, the earphone provided in this application has a deformation component 2 made of carbon fiber composite material. When the carbon fiber composite material is energized, the internal ions migrate by adjusting its voltage, thereby achieving deformation. After deformation, the power is turned off, which can effectively maintain the deformed state.

[0061] Specifically, when a positive voltage is applied to the deformation member 2, the deformation member 2 can deform in a direction away from the central axis of the ear cap 1 and cause the ear cap 1 to expand. When a negative voltage is applied to the deformation member 2, the deformation member 2 can deform in a direction closer to the central axis of the ear cap 1 and cause the ear cap 1 to contract.

[0062] like Figures 6 to 10 As shown, the earphone provided in this application includes a deformable component 2 comprising a first carbon fiber layer 21, an electrolyte membrane layer 22, and a second carbon fiber layer 23. Both the first carbon fiber layer 21 and the second carbon fiber layer 23 are doped with lithium ions 26. The electrolyte membrane layer 22 is equivalent to a structural battery electrolyte. When energized, the lithium ions 26 in the first carbon fiber layer 21 and the second carbon fiber layer 23 migrate between them through the electrolyte membrane layer 22, thereby causing deformation.

[0063] The first carbon fiber layer 21 is fixedly connected to the inner surface of the ear cap 1, the second carbon fiber layer 23 is located on the side of the first carbon fiber layer 21 near the central axis of the ear cap 1, and the electrolyte membrane layer 22 is fixedly connected between the first carbon fiber layer 21 and the second carbon fiber layer 23.

[0064] like Figure 11 As shown, when the deformation member 2 is positively charged, lithium ions 26 in the second carbon fiber layer 23 migrate through the electrolyte membrane layer 22 to the first carbon fiber layer 21. At this time, the second carbon fiber layer 23 is a discharge layer, and the discharge causes contraction. The first carbon fiber layer 21 is a charging layer, and the charging causes expansion. This causes the deformation member 2 to bend and bulge in a direction away from the central axis of the ear cap 1, which in turn causes the ear cap 1 to expand.

[0065] like Figure 12 As shown, when a negative voltage is applied to the deformation member 2, lithium ions 26 in the first carbon fiber layer 21 migrate through the electrolyte membrane layer 22 to the second carbon fiber layer 23. At this time, the first carbon fiber layer 21 is a discharge layer, and the discharge causes contraction. The second carbon fiber layer 23 is a charging layer, and the charging causes expansion. This causes the deformation member 2 to bend and bulge in the direction close to the central axis of the ear cap 1, which in turn causes the ear cap 1 to contract.

[0066] When the deformable component 2 is de-energized, the lithium ions 26 in the first carbon fiber layer 21 and the second carbon fiber layer 23 stop migrating and remain stationary, thus effectively maintaining the shape of the deformable component 2.

[0067] During the process of the deformation member 2 bending and protruding in a direction away from the central axis of the ear cap 1 and bending and protruding in a direction closer to the central axis of the ear cap 1, the lithium ions 26, which were concentrated in one of the first carbon fiber layer 21 and the second carbon fiber layer 23, first migrated to a state in which the lithium ions 26 in the first carbon fiber layer 21 and the lithium ions 26 in the second carbon fiber layer 23 were in equilibrium, and then continued to migrate to a state in which they were concentrated in the other of the first carbon fiber layer 21 and the second carbon fiber layer 23. This caused the deformation member 2 to first return to its initial state from the state of bending towards one side, and then bend and protrude towards the other side.

[0068] like Figures 13 to 15 As shown, the earphone provided in this application has a strip-shaped deformation member 2 and multiple deformation members 2. The deformation structure extends approximately along the circumference of the ear cap 1 and the direction of its central axis. Multiple deformation members 2 are spaced apart along the circumference of the ear cap 1 to ensure that multiple deformation members 2 deform synchronously, thereby causing the ear cap 1 to expand or contract uniformly.

[0069] like Figures 16 to 18 As shown, the earphone provided in this application has a ring-shaped deformation member 2 and multiple deformation members 2 are provided, and the multiple deformation members 2 are spaced apart along the extension direction of the central axis of the ear cap 1.

[0070] Along the extension direction of the central axis of the ear cap 1, the diameter of each deformation member 2 is adjusted according to the shape of the ear cap 1. The diameters of each deformation member 2 can be the same or different. By setting multiple deformation members 2 with annular structures, each deformation member 2 can be deformed synchronously to drive the ear cap 1 to expand or contract uniformly.

[0071] like Figure 19 and Figure 21 As shown, in the earphone provided by this application, the deformation member 2 has a mesh structure and is evenly distributed on the inner surface of the ear cap 1 to further improve the uniformity of the support of the deformation member 2 on the ear cap 1. When the deformation member 2 deforms, the ear cap 1 will generate uniform elastic deformation synchronously at all points.

[0072] like Figures 19 to 21 As shown, the earphone provided in this application includes a deformable component 2 comprising a plurality of first deformable elements 24 and a plurality of second deformable elements 25. The first deformable elements 24 are strip-shaped and are provided in multiples, with the plurality of first deformable elements 24 spaced apart along the circumference of the ear cap 1. The second deformable elements 25 are strip-shaped and are provided in multiples, with the plurality of second deformable elements 25 spaced apart along the circumference of the ear cap 1. Each first deformable element 24 and each second deformable element 25 extends approximately along the extension direction of the central axis of the ear cap 1, and each first deformable element 24 and each second deformable element 25 extends spirally along the circumference of the ear cap 1. The extension directions of the first deformable elements 24 and the second deformable elements 25 along the circumference of the ear cap 1 are opposite, so that the first deformable elements 24 and the second deformable elements 25 intersect and connect to form a mesh structure.

[0073] like Figure 1 As shown, the earphone provided in this application includes a body 3, and an ear cap 1 is detachably installed on the body 3. The body 3 is used for the user to hold and insert the ear cap 1 into the ear. The body 3 also contains other structural components of the earphone, such as electronic control components and a battery, to realize the complete function of the earphone. The battery can be used to provide voltage to the deformation component 2, and the electronic control components are used to control whether the voltage supplied to the deformation component 2 is positive or negative.

[0074] like Figure 1 As shown, the earphone provided in this application further includes a first detection control element 4 and a second detection control element 5, which are used to detect the overall usage status of the earphone and thereby control the expansion and contraction of the ear cap 1 according to the usage status.

[0075] The first detection and control element 4 is disposed on the ear cap 1 and electrically connected to the deformation member 2. The first detection and control element 4 is used to detect the first pressure on the ear cap 1. Specifically, when the ear cap 1 enters the user's ear, the outer surface of the ear cap 1 contacts the user's ear and is subjected to the first pressure. At this time, the specific pressure value of the first pressure is detected to determine whether the headphones are in a wearing state.

[0076] The second detection control element 5 is disposed on the body 3 and electrically connected to the deformation member 2. The second detection control element 5 is used to detect the second pressure applied to the body 3. Specifically, when the user needs to remove the earphone, he / she can hold the body 3 with his / her fingers to apply the second pressure to the body 3. By detecting the specific pressure value of the second pressure, it is determined whether the user needs to remove the earphone.

[0077] When the first pressure is greater than or equal to the first threshold and the second pressure is less than the second threshold, it is determined that the earphone is in a wearing state and the user has no intention of removing the earphone. The deformation member 2 can deform in a direction away from the central axis of the ear cap 1 and drive the ear cap 1 to expand, so as to ensure the reliability of the earphone wearing and prevent the earphone from falling out. When the second pressure is greater than the second threshold, it is not necessary to consider the pressure value of the first pressure, so it can be directly determined that the user needs to remove the earphone. Therefore, the deformation member 2 can deform in a direction closer to the central axis of the ear cap 1 to drive the ear cap 1 to contract, so as to reduce the friction between the ear cap 1 and the user's ear and facilitate the earphone to be removed smoothly. When the first pressure is less than the first threshold and the second pressure is equal to the second threshold, it is determined that the ear cap 1 is in a non-wearing state. At this time, according to the deformation of the deformation member 2, a positive voltage or a negative voltage is applied to it to make the ear cap 1 return to the initial state.

[0078] Optionally, both the first detection control element 4 and the second detection control element 5 are pressure sensors.

[0079] Optionally, the first threshold is greater than 0N to ensure that the ear cap 1 will expand and deform only after the first pressure reaches a certain pressure value, preventing accidental contact and unnecessary deformation of the ear cap 1; the second threshold is greater than or equal to 0N to ensure that the second detection control element 5 deforms immediately after detecting the second pressure, thereby improving its sensitivity. The specific values ​​of the first and second thresholds can be adjusted according to actual needs, and this application is not limited thereto.

[0080] The earphone provided in this application, when the ear cap 1 is placed in the user's ear, can be energized to cause the deformation element to deform in a direction away from the central axis of the ear cap 1, thereby expanding the ear cap 1 and increasing the friction between the ear cap 1 and the user's ear. After the power is turned off, the deformation state is maintained, so that the ear cap 1 is tightly abutted and positioned against the user's ear. When the earphone needs to be removed after use, the deformation element can be energized to deform in a direction closer to the central axis of the ear cap 1, thereby causing the ear cap 1 to contract and reduce the friction between the ear cap 1 and the user's ear, so as to facilitate its removal from the user's ear.
