[0003] The size of watches continues to develop in the direction of being smaller and thinner, but due to its structure and size limitations, the space occupied by the speakers inside the watch is gradually decreasing, the low-frequency effect of the speakers is poor, and the audio effect of the watch is poor. The watch is also equipped with a waterproof exhaust component, and exhaust holes are opened on the shell to guide air and balance the internal and external air pressure. It is very common for users to wash their hands, take a bath, swim, etc. when wearing it. It is easy for water and stains to enter the exhaust hole channel, causing the exhaust hole to be blocked and the speaker function to fail, which in turn makes the audio effect of the watch poor.

[0039] In the related art, due to the limitation of the size and structure of the watch, only devices of smaller size and specifications can be selected, and it is difficult to take into account the performance requirements of each frequency band, which makes it difficult to lose most of the low-frequency effects when the watch is actually used, especially when playing music, and the external speaker effect of the watch is poor, and the audio effect is poor. At the same time, the cavity in the watch shell serves as the working cavity of the speaker, and it is also necessary to form a special exhaust hole on the shell to balance the internal and external pressure difference when the speaker is working to avoid functional failure. However, watches are usually 5ATM waterproof products, and a few are IPX8 waterproof products. Washing hands, bathing, swimming and other scenes are very common during use, and it is easy for the exhaust holes to get water in and dirt to clog the holes, making the speaker function ineffective and the audio effect of the watch poor.

[0040] One solution to the problem of the exhaust hole being blocked and causing the speaker to fail is to use a speaker with a self-decompression function, which has the function of balancing the internal and external air pressure. For example, an air-release structure is set on the diaphragm surface of the speaker, and the sound outlet of the speaker is directly connected to the outside world. However, when the above-mentioned watch is tested in the reliability environment, especially the sweat resistance test, the corrosive steam will pass through the air-release structure and directly contact the internal magnetic circuit of the speaker, causing serious corrosion to the magnetic circuit of the speaker, making the speaker fail. In addition, the unit price of the speaker with a self-decompression function is also relatively high, lacking price advantage.

[0041] To this end, an embodiment of the utility model provides a watch, which includes a shell and a diaphragm assembly, the shell having a housing cavity and an opening portion connected to the housing cavity. The diaphragm assembly is arranged in the housing cavity and covers the opening portion, the diaphragm assembly includes an elastic membrane and a waterproof breathable membrane, the elastic membrane is provided with an exhaust hole, and the waterproof breathable membrane covers the exhaust hole. The airflow in the housing cavity can be used to drive the elastic membrane to vibrate, so that the elastic membrane and the housing cavity form a flexible cavity, improve the low-frequency loudness of the speaker, and thus improve the audio effect of the watch. The exhaust hole on the elastic membrane can be used for exhaust, the waterproof breathable membrane can be waterproof, and balance the air pressure inside and outside the shell. When the elastic membrane vibrates, it can also effectively radiate airflow outward to discharge water stains and foreign matter entering the surface of the elastic membrane and the waterproof breathable membrane, ensuring that the exhaust hole will not be blocked by water stains, stains, foreign matter, etc., causing the speaker to fail. In addition, by opening an exhaust hole on the elastic membrane and providing a waterproof breathable membrane, it is possible to avoid setting the exhaust hole inside the watch, thereby saving the stacking and ornament space inside the watch.

[0042] In order to make the above-mentioned purposes, features and advantages of the embodiments of the utility model more obvious and easy to understand, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0043] See also Figures 1 to 7 The embodiment of the utility model provides a watch, which may be a smart watch, and includes a housing 10 and a diaphragm assembly 30. The housing 10 has a receiving cavity 11 and an opening portion communicating with the receiving cavity 11, and the receiving cavity 11 may be stacked and decorated. For example, the diaphragm assembly 30 may be disposed in the receiving cavity 11, and other structures, such as a control module, may also be disposed.

[0044] like Figure 1 As shown, the housing 10 may be a hollow cubic structure, or other hollow structures, such as a cylindrical structure or a prism structure. Exemplarily, the housing 10 includes a top cover and a bottom shell that are relatively arranged, and a middle frame connected between the top cover and the bottom shell, and the top cover, the middle frame and the bottom shell enclose a receiving cavity 11.

[0045] The top cover forms the top wall of the accommodating cavity 11, which may be a display panel. The top cover and the middle frame are detachably connected, and the display panel may also be electrically connected to the control module to control the display panel to display. The middle frame forms the side walls of the accommodating cavity 11, and the bottom shell forms the bottom wall of the accommodating cavity 11. The middle frame and the bottom shell may be an integral structure, for example, the middle frame and the bottom shell are integrally formed, and the side walls, top wall, and bottom wall of the accommodating cavity 11 form the wall surface of the accommodating cavity 11.

[0046] The housing 10 is provided with an opening, which is in communication with the accommodating cavity 11, so that the sound generated by the speaker 20 can be transmitted to the outside of the housing 10. The opening can be provided on the side wall or the bottom wall of the accommodating cavity 11. For example, there are multiple openings, some of which are provided on the side wall of the accommodating cavity 11, and another part of which is provided on the bottom wall of the accommodating cavity 11. The opening can also be provided on the side wall of the accommodating cavity 11, so that when the wearer is wearing the opening, the opening will not be blocked by the wrist, thereby ensuring that the sound of the speaker 20 can be transmitted.

[0047] In some possible implementations, such as Figure 2 As shown, the opening portion includes a groove 12 and a through hole 13 arranged at the bottom of the groove 12, and the groove 12 is located on the side of the through hole 13 adjacent to the accommodating cavity 11. That is, the groove 12 is closer to the accommodating cavity 11, and the through hole 13 is closer to the outside of the housing 10. The groove 12 can be adapted to the diaphragm assembly 30 to facilitate the installation and fixing of the diaphragm assembly 30, and a vibration displacement space can be reserved for the diaphragm assembly 30.

[0048] The groove 12 is a stepped groove, and the step surface 14 of the stepped groove is away from the through hole 13, that is, the step surface 14 of the stepped groove faces the accommodating cavity 11. Specifically, the stepped groove includes a first groove section and a second groove section, the bottom wall of the first groove section begins to have the second groove section, the bottom wall of the second groove section is provided with the through hole 13, and the remaining bottom wall of the first groove section forms the step surface 14. The diaphragm assembly 30 is fixedly connected to the step surface 14, for example, the periphery of the diaphragm assembly 30 is glued to the step surface 14.

[0049] The diaphragm assembly 30 is fixed by the first groove section, and the distance between the diaphragm assembly 30 and the through hole 13 is ensured by the second groove section, so as to ensure the fixation and vibration of the diaphragm assembly 30. At the same time, the diaphragm assembly 30 is at least partially recessed in the side wall of the accommodating cavity 11, and the diaphragm assembly 30 is elastic and thin, which can also reduce the space occupied by the diaphragm assembly 30 in the accommodating cavity 11, thereby saving space in the accommodating cavity 11.

[0050] A plurality of through holes 13 may be provided, and the plurality of through holes 13 are arranged at intervals. By providing a plurality of through holes 13, a mesh cover may be formed at one end of the opening portion adjacent to the outside of the housing 10, so that the diaphragm assembly 30 may be protected and the diaphragm assembly 30 may be prevented from being damaged. The shape of the through hole 13 may be circular, elliptical, rectangular, etc., and the embodiment of the present application is not limited thereto.

[0051] In some other possible implementations, the opening portion includes a groove, the groove is a stepped groove, the stepped surface of the stepped groove faces the accommodating cavity, and the diaphragm assembly is fixedly connected to the stepped surface, for example, the periphery of the diaphragm assembly is glued to the stepped surface. Such an arrangement can simplify the structure of the opening portion and facilitate the processing and molding of the opening portion.

[0052] In some possible examples, the watch further includes a speaker 20, which is disposed in the accommodating cavity 11, for example, the speaker 20 is disposed on the side wall of the accommodating cavity 11 and is opposite to the diaphragm assembly 30. The speaker 20 is also directly opposite to at least a portion of the corresponding opening, and the orthographic projection of the speaker 20 on the side wall where the opening is located coincides with a portion of the orthographic projection of the diaphragm assembly 30 on the side wall. In this way, the diaphragm assembly 30 is located on the propagation path of the speaker 20, and the speaker 20 can be used to realize the vibration of the diaphragm assembly 30.

[0053] Specifically, when the speaker 20 is working, a large airflow is formed in the accommodating cavity 11 of the watch, and the airflow synchronously pushes the diaphragm assembly 30 to generate strong vibrations, which can effectively shake off and discharge water stains, stains, foreign objects, etc. attached to the surface of the diaphragm assembly 30 to avoid clogging. On the other hand, the passive vibration of the diaphragm assembly 30 is realized, that is, the diaphragm assembly 30 vibrates synchronously when the speaker 20 is working, and the working effect is good without adding other complicated designs and operations.

[0054] In some possible examples, the speaker 20 and the opening are respectively disposed on two opposite side walls of the accommodating cavity 11. Figure 5 As shown, the speaker 20 is arranged on the rear side wall of the accommodating cavity 11, and the opening is arranged on the front side wall of the accommodating cavity 11. In this arrangement, the opening and the diaphragm assembly 30 are both far away from the speaker 20, and the airflow radiated by the speaker 20 when working can produce the most effective convection, which is easier to drive the diaphragm assembly 30 to vibrate. At the same time, environmental tests and sweat resistance tests will not affect the magnetic circuit of the speaker 20, so as to prevent the speaker 20 from being corroded and failing in the environmental tests and sweat resistance tests.

[0055] See also Figure 3The diaphragm assembly 30 is disposed in the accommodating cavity 11 and covers the opening. The diaphragm assembly 30 includes an elastic membrane 31 and a waterproof breathable membrane 36. The elastic membrane 31 is provided with an exhaust hole 34, and the waterproof breathable membrane 36 covers the exhaust hole 34. The diaphragm assembly 30 covers the opening and is sealed with the housing 10 to prevent water stains, dirt, foreign matter, etc. from entering between the diaphragm assembly 30 and the opening.

[0056] The airflow in the accommodating cavity 11 can be used to push the elastic membrane 31 to vibrate, so that the elastic membrane 31 and the accommodating cavity 11 form a flexible cavity, thereby improving the low-frequency loudness of the speaker 20 and thus improving the audio effect of the watch. Figure 7 The frequency response curve of the watch shown in the figure, the frequency in the frequency response curve refers to the frequency, and the response in the frequency response curve can be regarded as the response of the watch to the frequency of the input electrical signal converted into sound energy. Figure 7 As shown in the figure, the circled curve is the frequency response curve of the watch with the diaphragm assembly, and the other curve is the frequency response curve of the watch without the diaphragm assembly. At low frequencies, the acoustic energy response of the watch with the diaphragm assembly is higher than that of the watch without the diaphragm assembly, and its low-frequency performance is better.

[0057] At the same time, the vent hole 34 on the elastic membrane 31 can be used to exhaust air, and the waterproof breathable membrane 36 can be waterproof and balance the air pressure inside and outside the housing 10. When the elastic membrane 31 vibrates, it can also effectively radiate airflow outward to exhaust water stains and foreign matter that enter the surface of the elastic membrane 31 and the waterproof breathable membrane 36, ensuring that the vent hole 34 will not be blocked by water stains, stains, foreign matter, etc., causing the speaker 20 to fail. In addition, by opening the vent hole 34 on the elastic membrane 31 and setting the waterproof breathable membrane 36, it is possible to avoid setting the vent hole 34 inside the watch, thereby saving the stacking and ornament space inside the watch.

[0058] The elastic membrane 31 is fixed and sealed with the housing 10, and the elastic membrane 31 can be extended, contracted and deformed toward the outside of the housing 10 to form an arc-shaped bending state. For example, by providing an opening on the side wall and / or the bottom wall of the accommodating cavity 11, and matching the opening with the shape of the elastic membrane 31, the elastic membrane 31 is fixed by bonding using the step surface 14 of the opening, and a certain distance is reserved for the deformation direction of the elastic membrane 31, so as to avoid interference when the elastic membrane 31 vibrates, and ensure that the elastic membrane 31 can work normally.

[0059] For some possible examples, see Figure 4 and Figure 5The elastic membrane 31 includes a first section 32, and a vent hole 34 is provided in the middle of the first section 32. The middle of the first section 32 is opposite to the opening, and the edge of the first section 32 surrounds the middle of the first section 32. The edge of the first section 32 is sealed and connected to the housing 10, thereby achieving the fixation between the elastic membrane 31 and the housing 10. Exemplarily, the edge of the first section 32 is bonded, clamped, etc. to the wall of the accommodating cavity 11, or the edge of the first section 32 is bonded, clamped, etc. to the opening (e.g., the step surface 14).

[0060] The middle part of the first section 32 is provided with an exhaust hole 34 so that the exhaust hole 34 is opposite to the opening. This arrangement can increase the contact area between the elastic membrane 31 and the housing 10, ensuring a reliable connection between the elastic membrane 31; and facilitates the exhaust hole 34 to be opposite to the through hole 13 and the speaker 20, ensuring the loudness and audio effect of the external speaker of the watch.

[0061] There may be a plurality of vent holes 34, and the plurality of vent holes 34 may form one or more rows and penetrate the first subsection 32. The ratio of the area of ​​the plurality of vent holes 34 to the opening area of ​​the groove 12 is greater than or equal to 25%, and / or the aperture of the vent holes 34 is greater than or equal to 0.1 mm and less than or equal to 0.3 mm. In this way, the ratio of the opening area of ​​the elastic membrane 31 to the effective air permeability area (i.e., the opening rate of the elastic membrane 31) is greater than or equal to 25%, and the vent holes 34 form a microporous structure.

[0062] Preferably, the opening rate of the elastic membrane 31 is greater than or equal to 25%, and the aperture of the exhaust hole 34 is between 0.1 mm and 0.3 mm. In this way, it is possible to avoid excessive air leakage from the exhaust hole 34 to cause sound leakage, and to avoid excessive air leakage from the exhaust hole 34 to cause unbalanced pressure difference between the inside and outside of the watch case 10, so that the speaker 20 can work normally and stably for a long time.

[0063] For some possible examples, see Figure 6 The elastic membrane 31 also includes a second subdivision 33 disposed on the side of the first subdivision 32 facing the waterproof breathable membrane 36. The second subdivision 33 is located in the middle of the first subdivision 32, and the exhaust hole 34 also penetrates the second subdivision 33. By arranging the second subdivision 33 in the middle of the first subdivision 32, the thickness and rigidity of the middle part of the elastic module can be increased, thereby avoiding deformation of the elastic membrane 31 during vibration, thereby ensuring the vibration and drainage effect of the elastic membrane 31. The second subdivision 33 is disposed between the waterproof membrane and the first subdivision 32, that is, the second subdivision 33 is located on the side of the first subdivision 32 away from the accommodating chamber 11, so as to avoid occupying the space of the accommodating chamber 11. The exhaust hole 34 also penetrates the second subdivision 33, so that the exhaust hole 34 penetrates the elastic membrane 31.

[0064] In some possible implementations, the second subsection 33 and the first subsection 32 are an integral structure. In this way, the elastic membrane 31 can be made of a monomer material, such as polyethylene naphthalate (PEN), polyetherimide (PEI), silicone rubber, etc., or an elastic material with a good Young's modulus, or the elastic membrane 31 can be a composite of the above elastic materials.

[0065] In some other possible examples, the rigidity of the second subsection 33 is greater than that of the first subsection 32, and the material of the first subsection 32 may be polyethylene naphthalate (PEN), polyetherimide (PEI), silicone rubber, etc. The material of the second subsection 33 may be a lightweight material with a certain rigidity, such as a hard material such as a carbon fiber composite material. The second subsection 33 may be attached to the first subsection 32.

[0066] The edge of the first subsection 32 is provided with an annular recess 35, which surrounds the exhaust hole 34 and the second subsection 33. The annular recess 35 is located in the opening, and the outer side of the annular recess 35 is connected to the shell 10, which is relatively fixed, and the inner side of the annular recess 35 is the exhaust hole 34 and the second subsection 33, which can vibrate. By providing the annular recess 35, the connection strength on both sides of the annular recess 35 can be increased, and the service life of the elastic membrane 31 can be improved. Exemplarily, the opening of the annular recess 35 faces the accommodating cavity 11, which facilitates the deformation of the elastic membrane 31 toward the opening.

[0067] See also Figures 1 to 6 The waterproof breathable membrane 36 is arranged on the side of the elastic membrane 31 away from the accommodating cavity 11, that is, the waterproof breathable membrane 36 is closer to the outside of the housing 10 relative to the elastic membrane 31, and the waterproof breathable membrane 36 can be bonded to the elastic membrane 31. The waterproof breathable membrane 36 covers the exhaust hole 34, for example, the waterproof breathable membrane 36 is bonded to the elastic membrane 31. On the one hand, it prevents water from entering the accommodating cavity 11 to ensure that the components in the accommodating cavity 11 can work normally, and on the other hand, it can balance the air pressure inside and outside the housing 10. The material of the waterproof breathable membrane 36 may include polytetrafluoroethylene material, Teflon or polyester. The air permeability of the waterproof breathable membrane 36 is greater than or equal to 2ml / min / 7Kpa, and less than or equal to 30ml / min / 7Kpa.

[0068] In order to achieve better drainage of water stains, dirt, foreign matter, etc., at least one of the elastic membrane 31 and the waterproof breathable membrane 36 has a nano coating on its surface. For example, the surfaces of the elastic membrane 31 and the waterproof breathable membrane 36 are both covered with nano coatings to improve the hydrophobic and oleophobic effects of the membrane assembly 30. The water drop angle of the nano coating is greater than or equal to 125° and less than or equal to 135°, and the oil drop angle of the nano coating is greater than or equal to 110° and less than or equal to 120°.

[0069] In summary, the watch in the embodiment of the present application includes a housing 10 and a diaphragm assembly 30, wherein the housing 10 has a housing cavity 11 and an opening portion connected to the housing cavity 11. The diaphragm assembly 30 is arranged in the housing cavity 11 and covers the opening portion. The diaphragm assembly 30 includes an elastic membrane 31 and a waterproof breathable membrane 36, wherein the elastic membrane 31 is provided with an exhaust hole 34, and the waterproof breathable membrane 36 covers the exhaust hole 34. The airflow in the housing cavity 11 can be used to drive the elastic membrane 31 to vibrate, so that the elastic membrane 31 and the housing cavity 11 form a flexible cavity, thereby improving the low-frequency loudness of the speaker 20, thereby improving the audio effect of the watch. The exhaust hole 34 on the elastic membrane 31 can be used for exhaust, and the waterproof breathable membrane 36 can be waterproof and balance the air pressure inside and outside the housing 10. When the elastic membrane 31 vibrates, it can also effectively radiate airflow outward to discharge water stains and foreign matter entering the surface of the elastic membrane 31 and the waterproof breathable membrane 36, ensuring that the exhaust hole 34 will not be blocked by water stains, stains, foreign matter, etc., causing the speaker 20 to fail. In addition, by opening the exhaust hole 34 on the elastic membrane 31 and providing the waterproof breathable membrane 36, it is possible to avoid providing the exhaust hole 34 inside the watch, thereby saving the stacking and ornament space inside the watch.
