[0046] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present disclosure. On the contrary, they are only examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0047] Figure 1 is a schematic structural diagram of a microphone module shown according to an exemplary embodiment. As Figure 1 shown, an embodiment of the present disclosure provides a microphone module, and the microphone module includes: a housing 1, a flexible circuit board 2, and a signal converter 3.

[0048] Among them, the housing 1 forms a cavity 11 with one end open; the flexible circuit board 2 is connected to the housing 1 to block the open end of the cavity 11; the signal converter 3 is used to convert sound signals into electrical signals and is placed inside the cavity 11.

[0049] During use, the cavity 11 of the housing 1 provides a stable working space for the signal converter 3; the sound signal is received by the signal converter 3 and converted into an electrical signal; the flexible circuit board 2 is connected to the installation area and / or other modules to fix and connect the microphone module.

[0050] The flexible circuit board 2 has the characteristics of being bendable and having good flexibility. When installing this microphone module, it can be attached to an uneven installation area through the flexible circuit board 2, such as an installation area with protrusions or depressions. Moreover, the flexible circuit board 2 can be bent. Therefore, when the installation area is insufficient or it is necessary to cooperate with other modules, the microphone module can be installed by bending the flexible circuit board 2. In the embodiments of the present disclosure, the installation requirements of this microphone module are reduced through the flexible circuit board 2, the installation flexibility of the microphone module is improved, and thus the applicable range of the microphone module is expanded.

[0051] In one embodiment, as Figure 1 shown, the flexible circuit board 2 includes: a carrying portion 21 and a connecting portion 22. Among them, the carrying portion 21 is connected to the housing 1 and the signal converter 3; the connecting portion 22 extends from one side of the carrying portion 21 and includes a free end 221 away from the carrying portion 22.

[0052] The signal converter 3 is a key component of the microphone module. Through the carrying portion 21, the stable installation of the signal converter 3 can be ensured, and thus the normal use of the microphone module can be guaranteed.

[0053] The free end 221 of the connecting portion 22 is used to connect to other modules or components, such as connecting to a control module to achieve effective control of the microphone module. Through the connecting portion 22, the optional installation positions of the microphone module are enriched. Exemplarily, the connecting portion 22 can adapt to different distances between the signal converter 3 and the target connection module or component, reducing the limitation of distance on the installation conditions of the microphone module. Figure 2 is a schematic diagram of the usage state of the flexible circuit board shown according to an exemplary embodiment. Exemplarily, as Figure 2 shown, the connecting portion 22 can be connected to the target connection module or component after being bent or curved to meet different spatial orientation requirements.

[0054] In this embodiment, the installation and connection methods of the microphone module are enriched through the bearing part 21 and the connecting part 22, making the microphone module applicable to more installation scenarios. Moreover, through the bearing part 21 and the connecting part 22, the applicable range of the microphone module is also expanded, especially suitable for terminal devices with a curved structure. The bendable bearing part 21 and connecting part 22 can fit on the curved structure, improving the adaptability of the microphone module to other modules or components in the terminal device.

[0055] Figure 3 It is a schematic structural diagram of a microphone module shown according to another exemplary embodiment. In one embodiment, as Figure 3 shown, a first slit 41 is provided on the part of the bearing part 21 corresponding to the cavity 11. Through the first slit 41, the deformation ability of the bearing part 21 can be further improved, the surface tension of the bearing part 21 can be enhanced, so that the bearing part 21 can fit more closely on the uneven installation area, ensuring the installation stability of the microphone module.

[0056] Among them, the number of the first slits 41 is not limited. It can be understood that the more the number of the first slits 41, the stronger the optimization effect on the deformation ability of the bearing part 21.

[0057] Regarding the distribution mode of the first slits 41, optionally, as Figure 2 shown, the connecting line of adjacent first slits 41 is an arc. In such a case, it helps the bearing part 21 to generate a bulging deformation or a concave deformation to adapt to installation areas of different shapes.

[0058] Figure 4 It is a schematic structural diagram of a microphone module shown according to another exemplary embodiment. In this embodiment, the sound receiving hole of the microphone module is provided on the flexible circuit board 2. As Figure 4 shown, a sound receiving hole 211 is also provided on the bearing part 21, and the first slit 41 is arranged around the sound receiving hole 211. In such a case, by providing the sound receiving hole 211 on the bearing part 21, the ductility of the bearing part 21 can be improved, and the deformation degree of the bearing part 21 can be increased. Exemplarily, the bearing part 21 can generate a convex deformation or a concave deformation centered on the sound receiving hole 11. Moreover, through the first slits 41 distributed around the sound receiving hole 211, the sound receiving hole 211 is assisted to further optimize the improvement effect and enhance the tension of the bearing part 21, making the microphone module adaptable to different installation conditions.

[0059] Figure 5 It is a schematic structural diagram of a bearing part shown according to an exemplary embodiment. In one embodiment, when the sound receiving hole of the microphone module is provided on the housing 1, optionally as Figure 5As shown, the first slits 41 are distributed divergently around the preset center. The first slits 41 distributed divergently around the preset center can also improve the deformation ability of the bearing portion 21, which helps the bearing portion 21 to produce a convex deformation or a concave deformation with the preset center as the vertex.

[0060] It should be noted that the optional first slit 41 is arranged on the side of the bearing part 21 away from the housing 1 and the signal converter 3, and does not penetrate the bearing part 21 in the thickness direction. Since the side of the bearing part 21 connecting the housing 1 and the signal converter 3 needs to be provided with wiring, solder joints and other structures, the first slit 41 is arranged on the side of the bearing part 21 away from the housing 1 and the signal converter 3, which will not affect the arrangement of wiring and solder joints, and is convenient for production and processing.

[0061] In one embodiment, Figure 3 As shown, a second slit 42 is provided on the connecting portion 22. The second slit 42 helps the connecting portion 22 to generate a stretching or bending deformation to meet different installation conditions.

[0062] Alternatively, if Figure 3 As shown, a second slit 42 is provided on one side of the connecting portion 22. It is understandable that the connecting portion 22 is more prone to bending or folding than when the second slit 42 is not provided; and the side of the connecting portion 22 provided with the second slit 42 has better stretchability than the side without the second slit 42.

[0063] Alternatively, if Figure 4 As shown, the second slits 42 are staggered on opposite sides of the connecting portion 22 . The staggered second slits 42 can prevent the connecting portion 22 from having a portion with a sudden size reduction, thereby ensuring the mechanical stability of the connecting portion 22 .

[0064] Optionally, a second slit 42 is provided on the side of the connecting portion 22. When the connecting portion 22 is bent, the deformation of the side is the largest, so providing the second slit 42 on the side of the connecting portion 22 helps to improve the bending deformation performance of the connecting portion 22.

[0065] Optionally, the second slits 42 are arranged side by side along the length direction of the connecting portion 22, which helps to enhance the elasticity of the connecting portion 22. When the connecting portion 22 is stretched, the width of the second slits 42 increases, and the length of the connecting portion 22 increases. In this case, when the microphone module and the module or component connected thereto are relatively displaced, the connecting portion 22 remains continuous, avoiding breakage that affects the normal use of the microphone module.

[0066] It should be noted that when the second slit 42 is provided on the connecting portion 22 , structures such as wiring or solder joints on the connecting portion 22 should be avoided to avoid affecting the normal use of the flexible circuit board 2 .

[0067] In this embodiment, the first slit 41 and the second slit 42 include arc-shaped ends, such as oval shapes, etc. The arc-shaped ends avoid stress concentration at the ends of the first slit 41 and the second slit 42, thereby preventing the flexible circuit board 2 from being torn at the first slit 41 and / or the second slit 42, and ensuring the safety of the device.

[0068] In one embodiment, the signal converter 3 includes a microelectromechanical systems (MEMS) sensor and an integrated circuit module electrically connected to the MEMS sensor. The integrated circuit module is connected to the flexible circuit board 2 and includes components with a surrounding structure, such as resistors, capacitors, etc. Compared with components with a linear structure, the surrounding structure helps to reduce the length and width of the components, enabling the integrated circuit module to achieve a smaller volume and reducing the installation space required for the overall microphone module.

[0069] A second aspect of the present disclosure provides a terminal device, which includes: the microphone module provided in the first aspect above. Since the terminal device adopts the microphone module provided in the first aspect above, the microphone module is suitable for various installation conditions. Therefore, the relative positions and connection methods of different modules are more flexible during the assembly of the terminal device, and different assembly methods can be realized to meet the user's needs.

[0070] Figure 6 It is a schematic structural diagram of a terminal device shown according to an exemplary embodiment. In one embodiment, as Figure 6 shown, the terminal device includes a display screen 6 that can be bent along a preset axis 5. The flexible circuit board 2 in the microphone module includes a bearing portion 21 and a connecting portion 22, and the free ends 221 of the bearing portion 21 and the connecting portion 22 are respectively arranged on both sides of the preset axis 5.

[0071] Optionally, the bearing portion 21 is arranged in a non-bending part to ensure the stability of the housing 1 and the signal converter 3. The connecting portion 22 is connected to other modules or components through the free end 221 that crosses the preset axis 5, realizing the cooperation between the microphone module and other modules and ensuring the normal use of the terminal. It can be seen that when the microphone module provided in the first aspect is applied to a terminal device with a bendable screen, it can not only meet the bending effect but also ensure the normal and stable use of the microphone module.

[0072] Exemplarily, the terminal device further includes a control module 7. The control module 7 and the signal converter 3 of the microphone module are respectively located on both sides of the preset axis 5, and the control module 7 is electrically connected to the free end 221. The control module 7 controls the microphone module by being electrically connected to the control module 7 across the preset axis 5 through the connecting portion 22. It can be seen from this example that the terminal device has the characteristic of flexible installation of internal modules, thereby realizing different assembly methods to meet user requirements and helping to reduce the assembly difficulty.

[0073] Among them, the preset axis 5 can be optionally the rotating shaft in the display screen 6; or the preset axis 5 is the axis, and the display screen 6 can be folded along this axis. The embodiments of the present disclosure do not specifically limit the implementation form of the preset axis 5.

[0074] In addition, in the embodiments of the present disclosure, the types of electronic devices are not specifically limited. Exemplarily, the electronic device can be a mobile phone, a computer, a laptop computer, a digital broadcast electronic device, a game console, a tablet device, a medical device, a fitness device, a personal digital assistant, etc.
