Description

Technical Field

[0001] This application relates to the field of headphone technology, and more particularly to a headphone and a smartwatch. Background Technology

[0002] With the development of society, in order to meet people's daily personal entertainment needs, people often use headphones to listen to music or make calls. Headphones are used in many environments. Sometimes people like to wear headphones while swimming or diving, which requires the waterproof performance of headphones.

[0003] However, the most common waterproof ratings for headphones on the market are IPX4 and IPX5.

[0004] Headphones with IPX4 and IPX5 ratings can withstand light rain and sweat, but they are still not ideal for users who need to use them in more humid environments, such as swimming or engaging in high-intensity exercise. Although some headphones do reach an IPX7 waterproof rating, the waterproof structure used at this level usually affects the headphone's sound performance to some extent, resulting in a decrease in sound quality.

[0064] Unless otherwise stated, "multiple" means two or more.

[0065] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0066] Please see Figure 1 , Figure 3 and Figure 5This application discloses an earphone 100, which includes a housing 1, an end cap 2, a speaker assembly 3, and a first waterproof and breathable membrane 4. The housing 1 has a first receiving cavity 1a with an open end. The end cap 2 is disposed at the opening of the first receiving cavity 1a and has a pressure relief hole 2a that penetrates the end cap 2 along a first direction X. The speaker assembly 3 is disposed within the first receiving cavity 1a and is sealed to the housing 1. The first waterproof and breathable membrane 4 is disposed between the end cap 2 and the speaker assembly 3, with a preset gap M between the first waterproof and breathable membrane 4 and the end cap 2, and the area of ​​the first waterproof and breathable membrane 4 is larger than the opening area of ​​the pressure relief hole 2a. In other words, the earphone 100 has a first waterproof and breathable membrane 4 disposed between the end cap 2 and the speaker assembly 3, with a preset gap M between the first waterproof and breathable membrane 4 and the end cap 2, and the area of ​​the first waterproof and breathable membrane 4 is larger than the opening area of ​​the pressure relief hole 2a on the end cap 2.

[0067] Wherein, the first direction X is the thickness direction of the end cap 2, that is... Figure 3 The direction from top to bottom and from bottom to top.

[0068] During operation, the pressure within the space between the speaker assembly 3 and the end cap 2 increases due to the operation of the speaker assembly 3. If the space is sealed, this increased pressure will affect the operation of the speaker assembly 3. Therefore, a pressure relief hole 2a needs to be provided in the end cap 2 to balance the pressure within the space between the speaker assembly 3 and the end cap 2 with the pressure outside the end cap 2, ensuring the normal operation of the speaker assembly 3. However, providing a pressure relief hole 2a in the end cap 2 requires waterproofing between the end cap 2 and the speaker assembly 3. If a high-density waterproof mesh is used between the speaker assembly 3 and the end cap 2 for waterproofing, the high density of the mesh will prevent the pressure between the end cap 2 and the speaker assembly 3 from being effectively released, thus affecting the normal operation of the speaker assembly 3.

[0069] Therefore, in this embodiment, the first waterproof and breathable membrane 4, positioned between the end cap 2 and the speaker assembly 3, effectively prevents moisture and dust from entering the earphone 100, protecting the speaker assembly 3 from damage due to water ingress. The pressure relief hole 2a penetrates the end cap 2 along the first direction X, working in conjunction with the first waterproof and breathable membrane 4 to ensure waterproofing and dustproofing while allowing air exchange between the inside and outside of the earphone 100. This helps balance the air pressure inside and outside the earphone 100, reducing sound distortion caused by pressure changes. The area of ​​the first waterproof and breathable membrane 4 is larger than the opening area of ​​the pressure relief hole 2a, resulting in a larger breathable area. This increases the amount of gas passing through the first waterproof and breathable membrane 4, preventing insufficient air permeability from affecting the operation of the speaker assembly 3. The preset gap M between the first waterproof and breathable membrane 4 and the end cap 2 ensures the breathability of the first waterproof and breathable membrane 4, thereby guaranteeing the normal operation of the speaker assembly 3 and the sound quality of the earphone 100.

[0070] Optionally, the area of ​​the first waterproof and breathable membrane 4 is greater than or equal to twice the opening area of ​​the pressure relief hole 2a. This ensures that the area of ​​the first waterproof and breathable membrane 4 is greater than or equal to twice the opening area of ​​the pressure relief hole 2a, further improving the breathability of the first waterproof and breathable membrane 4. This allows for smoother air exchange between the inside and outside of the earphone 100, helping to balance the air pressure inside and outside the earphone and reducing sound distortion or discomfort caused by air pressure changes. Simultaneously, the combined effect of the first waterproof and breathable membrane 4 and the pressure relief hole 2a, while ensuring waterproofing and dustproofing, increases the area of ​​the waterproof and breathable membrane, further reducing sound distortion caused by air pressure changes and improving the acoustic performance of the earphone.

[0071] It should be noted that the area of ​​the first waterproof and breathable membrane 4 can also be less than twice the opening area of ​​the pressure relief hole 2a. That is, the area of ​​the first waterproof and breathable membrane 4 is greater than twice the opening area of ​​the pressure relief hole 2a but less than twice the opening area of ​​the pressure relief hole 2a. This embodiment does not make specific limitations on this.

[0072] Furthermore, the circumferential edge of the first waterproof and breathable membrane 4 is bonded to the side of the end cap 2 facing the first receiving cavity 1a. That is, the first waterproof and breathable membrane 4 is bonded to the end cap 2 using double-sided adhesive, and the preset gap M between the first waterproof and breathable membrane 4 and the end cap 2 can be adjusted by adjusting the thickness of the double-sided adhesive. This bonding method between the circumferential edge of the first waterproof and breathable membrane 4 and the end cap 2 enhances the sealing between them, reducing the risk of leakage due to gaps. Moreover, by adjusting the thickness of the double-sided adhesive, the size of the preset gap M can be changed, thereby ensuring the breathability of the first waterproof and breathable membrane 4 as its area increases.

[0073] Optionally, such as Figure 4 and Figure 5As shown, the first waterproof and breathable membrane 4 includes a main body 41 and an extension 42, with the main body 41 connected to the extension 42, and the extension 42 corresponding to the pressure relief hole 2a. This precise alignment of the extension 42 with the pressure relief hole 2a ensures effective coverage of the first waterproof and breathable membrane 4 at the pressure relief hole 2a. This design prevents moisture from seeping into the equipment through the pressure relief hole 2a while ensuring the free flow of gas molecules, achieving both waterproof and breathable functions. Because the extension 42 directly corresponds to the pressure relief hole 2a, gas molecules can pass through the vent more smoothly during diffusion, thereby improving breathability.

[0074] Optionally, the first waterproof and breathable membrane 4 is made of polyetheretherketone (PEEK). Because PEEK waterproof and breathable membranes have a microporous structure, allowing gas molecules to pass freely while blocking moisture and dust, and due to PEEK's excellent waterproof properties, the first waterproof and breathable membrane 4 has a high waterproof rating, achieving IPX7. Furthermore, PEEK possesses excellent mechanical properties, including high strength, high toughness, and fatigue resistance. This allows the PEEK-made first waterproof and breathable membrane 4 to withstand significant external impacts and compression, adapting to pressure changes within the earphone 100, thus preventing damage or deformation and ensuring its long-term stability and reliability. This guarantees the long-term waterproof effectiveness between the earphone 100's end cap 2 and the speaker assembly 3.

[0075] It is worth noting that the material of the first waterproof and breathable membrane 4 can be polyetheretherketone (PEEK), polyethylene terephthalate (PEEK), liquid crystal polymer (LCP), or other materials with good waterproof properties. This embodiment does not impose specific limitations on this. Taking LCP as an example, LCP's high strength characteristics enable it to resist external pressure and abrasion, thereby extending the service life of the waterproof and breathable membrane. At the same time, LCP's water resistance and chemical stability make it one of the ideal materials for waterproof and breathable membranes. It can effectively prevent moisture penetration while maintaining internal air circulation.

[0076] In some embodiments, such as Figure 5 As shown, there are multiple pressure relief holes 2a, which are spaced apart along the circumference of the end cover 2. In this way, multiple pressure relief holes 2a are provided along the circumference of the end cover 2, which increases the space between the end cover 2 and the speaker assembly 3 and the area for air circulation with the outside, ensuring the pressure balance between the inside of the earphone 100 and the outside, and ensuring the normal operation of the speaker assembly 3.

[0077] Furthermore, combined Figure 5 and Figure 6The outer surface of the end cap 2 is provided with a first dustproof component 21, which corresponds to the pressure relief hole 2a and is arranged around the circumference of the end cap 2. In this way, by providing the first dustproof component 21, external dust, impurities, and other particles can be effectively blocked from entering the pressure relief hole 2a. Since the first dustproof component 21 is arranged around the circumference of the end cap 2, it can achieve complete coverage of the pressure relief hole 2a, further improving the dustproof effect. In addition, the first dustproof component 21 not only has a dustproof function but also serves as a decorative part of the end cap 2, enhancing the overall aesthetics of the earphone 100.

[0078] In some embodiments, see Figure 3 , Figure 7 and Figure 8 The earphone 100 also includes a support member 5, which is disposed within the first accommodating cavity 1a and surrounds the outer periphery of the speaker assembly 3. The support member 5 has a first end 51 and a second end 52 that are opposite to each other along a first direction X. A sealant is provided between the first end 51 and the end cap 2, and a sealant is provided between the second end 52 and the housing 1. That is to say, a support member 5 is provided between the end cap 2 and the housing 1, a sealant is provided between the first end 51 of the support member 5 and the end cap 2, and a sealant is provided between the second end 52 of the support member 5 and the housing 1.

[0079] In this way, the use of support component 5 and sealant enhances the durability of the internal structure of the earphone 100, preventing damage caused by long-term use or external impact. The sealant not only provides a sealing function but also absorbs vibration and impact to a certain extent, protecting the speaker assembly 3 and support component 5 from damage. Simultaneously, the sealant effectively prevents moisture and dust from entering the earphone 100, thus protecting the speaker assembly 3. The combination of support component 5 and sealant forms an effective waterproof and dustproof barrier, improving the overall waterproof rating of the earphone 100.

[0080] In some embodiments, such as Figure 3 As shown, the speaker assembly 3 includes a speaker diaphragm 31, which is made of polyethylene terephthalate (PET). Due to the high mechanical strength and stiffness of PET, the speaker diaphragm 31 can maintain a stable shape when subjected to sound vibrations, reducing distortion. High rigidity helps ensure accurate transmission of sound signals and improves the sound reproduction capability of the speaker assembly 3. PET material itself has low water absorption and good waterproof performance. When the speaker diaphragm is made of PET, an effective waterproof layer can be formed on its surface, effectively preventing water penetration and erosion. This means that even if the speaker assembly 3 is used in humid or underwater environments such as bathrooms or swimming pools, the PET diaphragm can maintain its structural integrity and performance stability, preventing moisture from damaging the interior of the speaker assembly 3.

[0081] It should be noted that, in addition to polyethylene terephthalate, the material of the speaker diaphragm 31 can also be polyetheretherketone (PEEK), liquid crystal polymer (LCP), expanded polytetrafluoroethylene (ePTFE), or other materials with good waterproof performance and elasticity. This embodiment does not make specific limitations on this.

[0082] Taking expanded polytetrafluoroethylene (ePTFE) as an example, ePTFE material has natural waterproof properties, and its microporous structure can effectively prevent water molecules from penetrating. This property allows the speaker diaphragm 31 to remain dry in humid or splashing environments, thus avoiding performance degradation or damage caused by moisture intrusion. Specifically, ePTFE waterproof membranes typically achieve IPX7 or IPX8 waterproof protection standards, meaning they effectively prevent water from passing through, providing a tight waterproof barrier for the speaker assembly 3. Simultaneously, the waterproof and breathable membrane made of ePTFE allows for free gas exchange between the inside and outside of the membrane, helping to balance the pressure within the speaker's sealed cavity and preventing airflow buildup, thereby ensuring the normal operation and optimal performance of the speaker assembly 3. This allows the speaker diaphragm 31 to not only have a waterproof function but also achieve a bass-low acoustic effect.

[0083] Furthermore, combined Figure 3 , Figure 9 and Figure 11 The housing 1 also includes a battery compartment 1b, which houses a battery P. The earphone 100 further includes a first sealing element 6, which separates the battery compartment 1b from the first accommodating cavity 1a. The first sealing element 6 and the speaker diaphragm 31 form a sound outlet channel Q. The housing 1 has a sound outlet hole 1c, which communicates with the sound outlet channel Q. In other words, the first sealing element 6 separates the battery compartment 1b from the first accommodating cavity 1a, the speaker diaphragm 31 and the first sealing element 6 form a sound outlet channel Q, and the housing 1 has a sound outlet hole 1c that communicates with the sound outlet channel Q for sound output.

[0084] In this way, the first sealing element 6 separates the first accommodating cavity 1a from the battery compartment 1b, thereby sealing the battery compartment 1b and preventing the battery P inside the battery compartment 1b from being damaged by water ingress. Simultaneously, when water enters the sound outlet channel Q formed by the speaker diaphragm 31 and the first sealing element 6, the water is blocked by the first sealing element 6 and the speaker diaphragm 31 within the sound outlet channel Q, thus protecting the internal components of the earphone 100 from water damage and ensuring the waterproof effect of the earphone 100.

[0085] It is understood that the first sealing element 6 can be a metal plate or a sealing plate made of other waterproof materials, and this embodiment does not specifically limit it.

[0086] In some embodiments, see Figure 3 , Figure 9and Figure 10 The first sealing member 6 has a first segment 61 and a second segment 62 connected to each other along the extension direction of the sound outlet channel Q. The first segment 61 is located near the battery P, and the second segment 62 is located near the speaker diaphragm 31. The edge of the second segment 62 is provided with a first positioning part 621, and the inner wall of the housing 1 is provided with a second positioning part 11. The first positioning part 621 and the second positioning part 11 cooperate to position the first sealing member 6 circumferentially.

[0087] In this way, by cooperating with the first positioning part 621 on the edge of the second segment 62 of the first sealing member 6 and the second positioning part 11 provided on the inner wall of the housing 1, the first sealing member 6 is positioned during installation, ensuring that the second segment 62 of the first sealing member 6 is located on the side away from the sound outlet 1c. A certain space is left between the lower part of the second segment 62 and the battery P. This space is used to accommodate the positive and negative terminal wiring of the battery P. By positioning the first sealing member 6 during installation, it is ensured that there is space to accommodate the positive and negative terminal wiring of the battery P and to seal and protect it. Furthermore, the cooperation between the first positioning part 621 and the second positioning part 11 makes it easier and faster to position the first sealing member 6 in the correct position during assembly.

[0088] In some embodiments, such as Figure 11 As shown, the inner wall of the housing 1 is also provided with a plurality of protruding structures 12, which are spaced apart along the circumference of the housing 1. The protruding structures 12 abut against the first sealing member 6, and sealant is provided in the interior of two adjacent protruding structures 12. That is to say, the first sealing member 6 abuts against the plurality of protruding structures 12 on the inner wall of the housing 1, and sealant is provided between two adjacent protruding structures 12.

[0089] In this way, the contact between the raised structure 12 and the first sealing element 6 increases the sealing contact area, making the seal tighter. The filling of sealant further enhances this tightness, effectively preventing moisture, dust, and other impurities from seeping into the interior of the housing 1 through the gaps. Furthermore, this design allows the first sealing element 6 to better conform to the inner wall of the housing 1, reducing sealing problems caused by shape mismatch.

[0090] Optionally, such as Figure 1 and Figure 11 As shown, the housing 1 is also provided with a second dustproof component 13, which is provided corresponding to the sound outlet 1c. The second dustproof component 13 can tightly cover the sound outlet 1c, effectively preventing external dust, dirt and other impurities from entering the earphone, which can further enhance the sealing of the earphone housing.

[0091] In some embodiments, see Figure 3The housing 1 includes a head housing 14 and a stem housing 15. The head housing 14 forms a first accommodating cavity 1a, and the stem housing 15 forms a second accommodating cavity 151. The earphone 100 also includes a microphone assembly 7, which is disposed in the second accommodating cavity 151. The stem housing 15 is also provided with a sound receiving hole 15a. The inner side of the microphone assembly 7 and the sound receiving hole 15a are sealed with a second waterproof and breathable membrane 8. In this way, the inner side of the microphone assembly 7 and the sound receiving hole 15a are sealed with the second waterproof and breathable membrane 8. This design ensures normal sound transmission while effectively preventing moisture from entering the second accommodating cavity 151 and damaging the microphone assembly 7.

[0092] Understandably, the first accommodating cavity 1a formed by the head housing 14 is used to house the main electronic components of the earphone, such as the speaker and battery, while the second accommodating cavity 151 formed by the stem housing 15 is used to house components such as the MIC assembly 7. The microphone hole 15a provided on the stem housing 15 provides a sound input channel for the MIC assembly 7, ensuring the sound quality of the earphone during calls or recordings.

[0093] Optionally, such as Figure 3 A third dustproof component 71 is provided between the second waterproof and breathable membrane 8 and the microphone hole 15a. By providing the third dustproof component 71, fine airborne particles, such as dust and pollen, can be effectively blocked, preventing these particles from entering the earphone 100 through the microphone hole 15a, thereby protecting the microphone assembly 7 from dust damage. This not only extends the service life of the microphone assembly 7 but also ensures the clarity and stability of sound transmission.

[0094] In some embodiments, such as Figure 1 and Figure 3 As shown, the earphone 100 also includes a probe 9, which extends into the second accommodating cavity 151 and is sealed to the stem housing 15. This sealed connection enhances the overall structural stability of the earphone, ensuring the probe 9 is firmly fixed to the stem housing 15 and less prone to loosening or falling off, thus improving the durability and lifespan of the earphone 100. The sealed connection between the probe 9 and the stem housing 15 also provides waterproofing and dustproofing, effectively preventing moisture and dust from entering the second accommodating cavity 151, thereby protecting the MIC assembly 7 and other electronic components from damage.

[0095] It is understood that the sealing connection between the probe 9 and the shank housing 15 can be achieved by filling with sealant, or by setting a rubber sealing ring. Of course, there are other ways to achieve a sealing connection, but this embodiment does not specifically limit them.

[0096] In some embodiments, combined with Figure 1 and Figure 3 The second accommodating cavity 151 includes a rotating cavity 151a, within which a rotating bracket 1511 is provided, and within the rotating bracket 1511 a rotating shaft 1512 is provided. The earphone 100 also includes a rotating arm 10, which is rotatably connected to the rotating shaft 1512. The second accommodating cavity 151 also includes a motherboard mounting cavity 151b, where a motherboard 1513 is mounted. The earphone 100 also includes a second sealing element 153, which separates the motherboard mounting cavity 151b from the rotating cavity 151a. That is, the second sealing element 153 is provided between the motherboard mounting cavity 151b and the rotating cavity 151a to achieve a seal between the two cavities.

[0097] Thus, the rotating cavity 151a houses a rotating bracket 1511 and a rotating shaft 1512. The rotating arm 10 of the earphone 100 is rotatably connected to the rotating shaft 1512, allowing the rotating arm 10 to rotate at a certain angle, increasing its flexibility of use. Users can adjust the position of the earphone according to their personal wearing habits or needs, improving wearing comfort. The motherboard mounting cavity 151b is separated from the rotating cavity 151a by a second seal 153. This design has two main advantages: firstly, it prevents dust, moisture, and other external substances from entering the motherboard mounting cavity 151b, protecting the motherboard 1513 and other electronic components from damage; secondly, it reduces interference from the rotating parts to the motherboard area, ensuring stable operation of the earphone.

[0098] It is understood that the second seal 153 can be a sealant, a rubber sealing ring, or other components that can achieve a waterproof sealing effect. This embodiment does not specifically limit this.

[0099] In some embodiments, such as Figure 3 As shown, the handle housing 15 extends inwardly with an abutment portion 152, which abuts against the side of the rotating bracket 1511 near the motherboard mounting cavity 151b. The rotating bracket 1511 has a groove 1511a on the side near the motherboard mounting cavity 151b. The second seal 153 includes a first part 1531 and a second part 1532 that are connected to each other along the first direction X. The first part 1531 extends into the groove 1511a and is sealed to the groove 1511a. The second part 1532 is sealed to the abutment portion 152.

[0100] In this way, the first part 1531 of the second seal 153 extends into the groove 1511a of the rotating bracket 1511 and is sealed to the groove 1511a, while the second part 1532 is sealed to the abutment part 152. This double-seal design significantly improves the sealing performance, ensuring that the motherboard mounting cavity 151b is completely separated from the rotating cavity 151a, guaranteeing the dryness of the motherboard mounting cavity 151b, and preventing water from entering the motherboard mounting cavity 151b and causing damage to the motherboard 1513. Furthermore, the abutment of the abutment part 152 to the rotating bracket 1511, and the double seal of the second seal 153 together form a stable structure. This helps reduce loosening or damage caused by vibration or external impact, improving the overall stability and reliability of the earphone 100.

[0101] See Figures 12 to 14 The second aspect of this application discloses a smartwatch 300, which includes a main unit 301, a watch strap 302, and multiple earphones 100 as described in the foregoing embodiments. A receiving cavity 300a is provided at the connection between the watch strap 302 and the main unit 301, and the earphones 100 are disposed within the receiving cavity 300a. The smartwatch 300 employing earphones 100 ensures the overall waterproof rating of both the smartwatch 300 and the earphones 100, allowing the earphones 100 to be compatible with the high waterproof performance of the smartwatch 300. This ensures that the smartwatch 300 and earphones 100 will not malfunction due to water ingress in humid environments such as swimming and diving, thus guaranteeing the waterproof effect of the smartwatch 300. Furthermore, even when a humid environment enters the receiving cavity 300a, the earphones 100 maintain sound quality while ensuring waterproofing.

[0102] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
