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] Most headphones on the market today prioritize wearing comfort and portability in their design, so they are generally lightweight and can be stored in a headphone case.

[0003] Since headphones do not need to withstand excessive pressure, headphone shells made of conventional plastic materials can meet their reliability requirements, such as drop tests and tumbling tests.

[0004] However, when earphones are used with a smartwatch, the earphones need to support the weight of the watch during use. This extra weight poses a challenge to the structural strength of the earphones. Earphones with a pure plastic shell may not be able to withstand the pressure of such weight when the watch is dropped, which may cause local deformation of the earphones and affect their functionality, rendering them unusable. Utility Model Content

[0005] This application discloses an earphone and a smartwatch, which effectively enhances the structural strength of the earphone and prevents the earphone shell from deforming due to a large impact when the earphone is dropped along with the smartwatch, thus ensuring the normal use of the earphone function.

[0020] As an optional implementation, the end cap is further provided with a reinforcing rib on the side facing the first accommodating cavity, and the reinforcing rib is disposed near the edge of the end cap.

[0021] As an optional implementation, the reinforcing rib is located between the mounting groove and the annular groove of the end cap.

[0060] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0061] Please see Figures 1 to 4 This application discloses an earphone 100, which includes a housing 1, an end cap 2, and a support member 3. A first receiving cavity 1a with an open end is formed within the housing 1. The end cap 2 is disposed at the opening of the first receiving cavity 1a. The support member 3 is disposed within the first receiving cavity 1a. The support member 3 has a first end 31 and a second end 32 that are opposite to each other along a first direction X. The first end 31 abuts against the end cap 2, and the second end 32 abuts against the housing 1. The abutment position of the support member 3 and the end cap 2 is close to the edge of the end cap 2. That is, a support member 3 is provided between the end cap 2 and the housing 1 of the earphone 100. The support member 3 has a first end 31 and a second end 32 along the first direction X. The first end 31 of the support member 3 abuts against the end cap 2, providing support for the end cap 2, and the second end 32 of the support member 3 abuts against the housing 1.

[0062] 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.

[0063] When the earphone 100 is dropped, the connection between the end cap 2 and the housing 1 often contacts the ground first. This causes the connection between the end cap 2 and the housing 1 to be impacted first. This impact force is transmitted to the housing 1 through the end cap, causing the housing 1 to deform. The deformation of the housing 1 will cause the internal components of the housing 1 to be damaged due to compression, which in turn causes the earphone 100 to malfunction.

[0064] Therefore, in this embodiment, the earphone 100 has a support member 3 between the end cap 2 and the housing 1. The first end 31 of the support member 3 abuts against the end cap 2, and the second end 32 abuts against the housing 1. By setting the support member 3 in the first accommodating cavity 1a, and with the first end 31 abutting against the end cap 2 and the second end 32 abutting against the housing 1, a stable support structure is formed, which effectively enhances the overall structural stability of the earphone 100. When the earphone 100 is subjected to external force, the impact force on the end cap 2 is transmitted to the support member 3, and then to the housing 1. In this process, the support member 3 shares the impact force at the connection between the end cap 2 and the housing 1. The impact force is small, so it is not easy to deform or be damaged, protecting the components inside the earphone 100 and ensuring the normal use of the earphone 100.

[0065] In some embodiments, such as Figure 3As shown, the earphone 100 also includes a speaker assembly 4, which is disposed within the first accommodating cavity 1a. The speaker assembly 4 is connected to the housing 1, and there is a preset gap M between the speaker assembly 4 and the end cover 2. That is to say, the speaker assembly 4 is arranged in the first accommodating cavity 1a, and the speaker assembly 4 is positioned close to the end cover 2, but there is a certain gap between the speaker assembly 4 and the end cover 2. The support member 3 holds the end cover 2 in place, so that there is no contact between the speaker assembly 4 and the end cover 2.

[0066] Since the speaker assembly 4 is the component used for sound production in the headphones 100, it is quite important. Therefore, there is a preset gap M between the speaker assembly 4 and the end cover 2 in the first accommodating cavity 1a of the headphones 100, ensuring that a certain gap is maintained between the speaker assembly 4 and the end cover 2. This prevents the speaker assembly 4 from contacting the end cover 2. When the side of the headphones 100 near the end cover 2 is impacted, the impact force will not directly impact the speaker assembly 4 through the end cover 2, thus ensuring the service life of the speaker assembly 4.

[0067] In some embodiments, such as Figure 3 As shown, the support member 3 is arranged around the outer periphery of the speaker assembly 4. That is to say, the support member 3 wraps around the outer periphery of the speaker assembly 4, similar to being sleeved on the speaker assembly 4. In this way, the support member 3, arranged around the outer periphery of the speaker assembly 4, can provide a stable support environment for it, and play a certain role in protecting the speaker assembly 4. When the earphone 100 is subjected to external impact, the support member 3 can absorb some of the impact energy and distribute it to the housing 1 and other components, which helps to reduce the impact force on the speaker assembly and improve its impact resistance.

[0068] In some embodiments, combined with Figures 5 to 7 The end cap 2 is provided with a pressure relief hole 2a extending along the first direction X. A first positioning part 21 is provided on the side of the end cap 2 facing the first accommodating cavity 1a, avoiding the pressure relief hole 2a. A second positioning part 31a is provided on the first end 31 of the support member 3. The first positioning part 21 and the second positioning part 31a cooperate to position the end cap 2 circumferentially. In other words, the first positioning part 21 on the side of the end cap 2 facing the first accommodating cavity 1a cooperates with the second positioning part 31a of the support member 3 to position the end cap 2 circumferentially, achieving precise positioning and stable installation of the end cap 2 in the circumferential direction.

[0069] Since the speaker assembly 4 generates sound through vibration, the pressure in the space between the speaker assembly 4 and the end cover 2 increases when the speaker assembly 4 is operating. Therefore, a pressure relief hole 2a is opened on the end cover 2 to balance the pressure in the space between the speaker assembly 4 and the end cover 2 with the external pressure, ensuring the normal operation of the speaker assembly 4. However, if the opening position of the pressure relief hole 2a is close to the sound output position of the headphone 100, it will affect the sound quality of the headphone 100. Therefore, it is necessary to position the installation direction of the end cover 2 to minimize the impact of the pressure relief hole 2a on the sound output position of the headphone 100.

[0070] In this embodiment, the first positioning part 21 provided on the side of the end cover 2 facing the first accommodating cavity 1a cooperates with the second positioning part 31a of the support member 3 to achieve precise positioning of the end cover 2 in the circumferential direction. This helps to ensure the positional accuracy of the end cover 2 during installation and prevents the sound quality of the headphones 100 from being affected because the pressure relief hole 2a on the end cover 2 does not avoid the sound output position of the headphones 100.

[0071] It is worth noting that the first positioning part 21 can be a positioning groove, and the second positioning part 31a can be a positioning protrusion. When the positioning protrusion is inserted into the positioning groove, positioning can be completed. Of course, the first positioning part 21 can also be a positioning protrusion and the second positioning part 31a can be a positioning groove, or the first positioning part 21 can also be a hook and the second positioning part 31a can be a slot. This embodiment does not make specific limitations on this.

[0072] In some embodiments, such as Figure 5 and Figure 7 As shown, the first end 31 of the support member 3 is an annular protrusion 311, and the end cover 2 is provided with an annular groove 22 on the side facing the first receiving cavity 1a. The annular protrusion 311 extends into the annular groove 22 to position the end cover 2 radially. That is to say, the annular protrusion 311 extends into the annular groove 22, so that the radial movement of the end cover 2 is restricted by the annular groove 22.

[0073] In this way, the engagement of the annular protrusion 311 and the annular groove 22 effectively positions the end cap 2 radially, preventing it from moving or shifting in the radial direction and ensuring that the end cap 2 accurately aligns with the opening of the first accommodating cavity 1a. Furthermore, the engagement of the annular protrusion 311 and the annular groove 22 also enhances the overall structural strength to a certain extent. When subjected to external impact or vibration, the annular protrusion 311 and the annular groove 22 can support each other, thereby dispersing and absorbing part of the impact force and protecting the entire end cap 2 from damage.

[0074] In some embodiments, combined with Figure 3 and Figure 5The annular protrusion 311 is provided with multiple first protrusion structures 311a, which are spaced apart circumferentially along the annular protrusion 311. The first protrusion structures 311a abut against the bottom of the annular groove 22, and a sealant is provided between two adjacent first protrusion structures 311a. That is to say, the first protrusion structures 311a on the annular protrusion 311 abut against the bottom of the annular groove 22 of the end cover 2, so that there is a certain gap between the annular protrusion 311 of the support member 3 and the bottom of the annular groove 22, and the sealant is provided in the gap.

[0075] In this way, the contact between the first protruding structure 311a and the bottom of the annular groove 22 forms a preliminary sealing line, effectively reducing the possibility of liquid leakage through this gap. Furthermore, the sealant between two adjacent first protruding structures 311a further enhances the sealing effect, ensuring a waterproof seal between the end cap 2 and the support member 3. In addition, the sealant fills the tiny gaps, forming a continuous sealing barrier, achieving the connection between the end cap 2 and the support member 3, thereby improving the overall sealing performance of the structure.

[0076] Furthermore, combined Figure 3 and Figure 6 The second end 32 of the support member 3 is provided with a plurality of second protrusions 312, which are spaced apart circumferentially along the second end 32 of the end cover 2. The second protrusions 312 abut against the housing 1, and a sealant is provided between two adjacent second protrusions 312. That is to say, the sealant is provided in the gap between the support member 3 and the housing 1 to achieve a sealed connection between the support member 3 and the housing 1. In this way, the sealant provided between the second protrusions 312 and the housing 1 effectively prevents the entry of external liquids, fills potential tiny gaps, further enhances the sealing effect, and ensures that water will not enter the first accommodating cavity 1a.

[0077] In some embodiments, combined with Figure 3 and Figure 6 The inner wall of the support member 3 has a first stepped surface 33, and the outer periphery of the speaker assembly 4 has a second stepped surface 41. The first stepped surface 33 and the second stepped surface 41 are arranged opposite to each other along the first direction X. The first stepped surface 33 is provided with an abutting part 331, which abuts against the second stepped surface 41.

[0078] Thus, by providing an abutment portion 331 on the first stepped surface 33 of the support member 3, on the one hand, when installing the support member 3 and the speaker assembly 4, it is only necessary to align the second stepped surface 41 of the speaker assembly 4 with the first stepped surface 33 of the support member 3 and gently push it in until the abutment portion 331 and the second stepped surface 41 are fully abutted. This also facilitates the positioning of the relative positions of the speaker assembly 4 and the support member 3 during installation, making installation easier. On the other hand, the abutment design of the first stepped surface 33 and the second stepped surface 41 provides a stable support platform for the speaker assembly 4, enhancing the stability of the speaker assembly 4 inside the support member 3 and preventing the speaker assembly 4 from shaking within the first receiving cavity 1a.

[0079] In some embodiments, the support member 3 is made of metal. The use of a metal material, such as stainless steel, aluminum alloy, or steel, gives the support member 3 high strength and rigidity, enabling it to withstand greater weight and pressure without easily deforming or damaging it. This allows the support member 3 to maintain stable performance during long-term use, extending the lifespan of the headphones 100. Simultaneously, the metal material of the support member 3 also provides good vibration resistance, reducing noise and interference caused by vibration.

[0080] Understandably, the material of the support component 3 can be metal or non-metallic plastic materials, such as polyoxymethylene, polycarbonate, or some polymer materials. Taking polycarbonate as an example, polycarbonate is used as the material for manufacturing the support component 3 because it has high strength and light weight. Therefore, the support component 3 made of polycarbonate can have high structural strength and can withstand the impact force on the end cap 2 of the earphone 100. In addition, polycarbonate itself is lightweight, so the support component 3 made of polycarbonate is even lighter, which helps to reduce the weight of the earphone 100 and provide a more comfortable wearing experience for the user of the earphone 100.

[0081] In some embodiments, such as Figure 3 and Figure 7 As shown, the thickness of the edge portion of the end cap 2 is greater than the thickness of the middle portion of the end cap 2. That is to say, the thickness of the edge portion of the end cap 2 is greater than the thickness of the middle portion of the end cap 2. Since the earphone 100 is dropped, the edge portion of the end cap 2 near the earphone stem usually contacts the ground first. This will cause the edge portion of the end cap 2 near the earphone stem to be subjected to the impact force first, resulting in deformation and damage of the edge of the end cap 2, and deformation and compression into the first receiving cavity 1a.

[0082] Therefore, in this embodiment, by setting the thickness of the edge portion of the end cap 2 to be greater than the thickness of the middle portion of the end cap 2, it is ensured that when the edge of the end cap 2 is subjected to external pressure or impact, the thicker edge portion can better resist deformation and damage, thereby protecting the end cap 2 and the components within the first accommodating cavity 1a below the end cap 2. Furthermore, the thickness of the edge portion of the end cap 2 differs from the thickness of the middle portion of the end cap 2 because the middle portion of the end cap 2 is less susceptible to impact and does not need to be made to the same thickness as the edge portion. This saves on the manufacturing cost of the end cap 2 and also reduces its weight to some extent.

[0083] Furthermore, such as Figure 7 and Figure 8 As shown, the end cap 2 has an installation groove 23 on the side facing the first accommodating cavity 1a. A waterproof and breathable membrane 231 is installed in the installation groove 23. The distance from the bottom of the installation groove 23 to the outer surface of the end cap 2 is less than the distance from the bottom of the annular groove 22 to the outer surface of the end cap 2.

[0084] In this way, the waterproof and breathable membrane set in the mounting groove 23 can prevent moisture and other liquids from entering the first accommodating cavity 1a, while allowing gas molecules to pass through, thereby maintaining the gas pressure balance and dry environment inside the first accommodating cavity 1a. Furthermore, the distance from the bottom of the mounting groove 23 to the outer surface of the end cap 2 is less than the distance from the bottom of the annular groove 22 to the outer surface of the end cap 2. This ensures that the thickness of the end cap 2 corresponding to the annular groove 22 is greater, resulting in better strength of the annular groove 22 portion, enabling it to withstand a certain amount of impact and protecting the internal structure of the earphone 100.

[0085] Optionally, such as Figure 7 As shown, the end cap 2 is also provided with a reinforcing rib 24 on the side facing the first receiving cavity 1a, and the reinforcing rib 24 is located near the edge of the end cap 2. That is to say, the edge of the end cap 2 facing the first receiving cavity 1a is provided with a reinforcing rib.

[0086] Thus, the reinforcing rib 24, acting as an additional supporting structure, significantly improves the overall strength and rigidity of the end cap 2. Especially when subjected to external pressure or impact, the reinforcing rib 24 effectively disperses and resists these forces, preventing deformation or breakage of the end cap 2. The reinforcing rib 24 positioned near the edge of the end cap 2 also enhances the load-bearing capacity of the edge, improving the overall stability and durability of the end cap 2. Simultaneously, the placement of the reinforcing rib 24 helps optimize the stress distribution within the end cap. When subjected to external forces, the reinforcing rib guides stress along a more rational path, avoiding stress concentration and excessive deformation, thus improving the load-bearing capacity and fatigue resistance of the end cap 2 and extending its service life.

[0087] Furthermore, such as Figure 7As shown, the reinforcing rib 24 is located between the mounting groove 23 and the annular groove 22 of the end cap 2. That is, the reinforcing rib 24 is positioned between the mounting groove 23 and the annular groove 22. Thus, by placing the reinforcing rib 24 at the position between the mounting groove 23 and the annular groove 22, the reinforcing rib 24 effectively separates the annular groove 22 from the mounting groove 23. The thicker annular groove 22 ensures structural strength, and the reinforcing rib 24 further guarantees the structural strength and rigidity of the end cap 2 at the position corresponding to the mounting groove 23, thereby ensuring the service life of the end cap 2.

[0088] Furthermore, such as Figure 7 As shown, the reinforcing rib 24 includes multiple arc-shaped sub-reinforcing ribs 241, which are spaced apart circumferentially around the end cap 2. That is, the reinforcing rib 24 is composed of multiple arc-shaped sub-reinforcing ribs 241 arranged circumferentially around the end cap 2. By providing multiple arc-shaped sub-reinforcing ribs 241 on the end cap 2, the structural strength and stiffness of the end cap 2 can be significantly improved. These arc-shaped sub-reinforcing ribs 241, like the supporting structure of a bridge, can effectively distribute and bear external pressure and load, thereby protecting the end cap 2 from damage. The circumferential spacing of the arc-shaped sub-reinforcing ribs 241 helps optimize the stress distribution on the end cap 2. When subjected to external forces, these arc-shaped sub-reinforcing ribs 241 can guide stress along a more reasonable path, avoiding stress concentration and sudden release, thereby reducing the risk of deformation and breakage of the end cap 2.

[0089] Optionally, the end cap 2 may be made of metal. The end cap 2 is made of metal, such as stainless steel, aluminum alloy or steel, which gives the end cap 2 high strength and rigidity, enabling it to withstand greater weight and pressure and to resist deformation or damage.

[0090] Understandably, the end cap 2 can also be made of non-metallic plastic materials, such as polyoxymethylene (POM), polycarbonate, or some polymer materials. Taking POM as an example, end cap 2 made of POM has high hardness, wear resistance, and good temperature resistance, ensuring that it is hard enough to withstand the impact of drops. Furthermore, it is more wear-resistant during daily use, can adapt to different temperatures, and will not deform at high temperatures, thus ensuring the service life of end cap 2.

[0091] In some embodiments, combined with Figure 1 and Figure 9The housing 1 includes a front shell 11 and a bottom shell 12 arranged along a first direction X. The front shell 11 and the bottom shell 12 are connected to each other. The inner wall of the bottom shell 12 is provided with an abutment surface 12a, which abuts against the second end 32 of the support member 3 along the first direction X. That is to say, the housing 1 is composed of a front shell 11 and a bottom shell 12, and the second end 32 of the support member 3 abuts against the abutment surface 12a of the bottom shell 12 along the first direction X.

[0092] In this way, the contact design between the contact surface 12a of the bottom shell 12 and the second end 32 of the support member 3 ensures that the support member 3 can be stably fixed inside the shell 1. This not only improves the supporting effect of the support member 3, but also enables it to better transmit and distribute pressure and load from the outside, thereby protecting other components inside the shell 1 from damage.

[0093] Furthermore, such as Figure 9 As shown, the bottom shell 12 is provided with a reinforcing portion 12b, which is located near the connection between the bottom shell 12 and the top shell 11. The thickness of the reinforcing portion 12b is greater than the thickness of the rest of the bottom shell 12. Thus, the reinforcement portion 12b, especially its increased thickness, significantly enhances the load-bearing capacity of the bottom shell 12 near the connection. This helps resist external pressure, impact, and vibration transmitted from the second end 32 of the support member 3, reducing stress concentration and lowering the risk of shell deformation and cracking, thereby improving the overall structural strength and stability of the shell. Furthermore, the larger thickness of the reinforcing portion 12b also increases the contact area between the support member 3 and the bottom shell 12, providing sufficient support for the support member 3 and ensuring its load-bearing capacity.

[0094] In some embodiments, combined with Figure 3 and Figure 6 The front shell 11 and the bottom shell 12 form a second accommodating cavity 1b, within which the main board 5 is housed. The support member 3 has a cable routing hole 3a through which the connection cable between the speaker assembly 4 and the main board 5 passes. In other words, the connection cable between the speaker assembly 4 and the main board 5 is routed through the cable routing hole 3a. This allows the connection cable between the speaker assembly 4 and the main board 5 to be neatly routed through the cable routing hole 3a on the support member 3, avoiding cable clutter and improving overall aesthetics and cleanliness. Simultaneously, neat wiring helps reduce interference and loss during signal transmission, thereby improving the signal transmission efficiency and stability between the speaker assembly 4 and the main board 5.

[0095] See Figures 10 to 12The 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. With the earphones 100, the smartwatch 300, even if dropped with the earphones 100 in place within the receiving cavity 300a, has sufficient structural strength to prevent deformation of the earphones 100 due to impact, thus ensuring normal operation of the earphones 100.

[0096] 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.
