[0011] Since in the audio device, the microphone is located between the bracket and the flexible circuit board, the bracket can play a supporting role, so the audio device can reduce the risk of the microphone falling off the bracket when no supporting member is provided.

[0053] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0054] The terms used in the following embodiments are only for the purpose of describing specific embodiments, and are not intended to be used as limitations on the present application. As used in the specification and the appended claims of the present application, the singular expressions "one", "a kind of", "said", "above", "the" and "this" are intended to also include expressions such as "one or more", unless there is a clear contrary indication in the context. It should also be understood that in the following embodiments of the present application, "at least one", "one or more" refer to one, two or more. The term "and / or" is used to describe the association relationship of associated objects, indicating that three relationships may exist; for example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0055] References to "one embodiment" or "some embodiments" etc. described in this specification mean that a particular feature, structure or characteristic described in conjunction with the embodiment is included in one or more embodiments of the present application. Thus, the phrases "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear at different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0056] In order to make the description of the following embodiments clear and concise, a brief introduction to the related technology is first given:

[0057] In order to meet user needs, some terminal devices are currently provided with an audio device, a microphone (MIC), and the microphone of some terminal devices is arranged on the back of the terminal device, that is, the sound outlet of the microphone is located on the back of the terminal device.

[0058] For example, some high-end mobile phones are equipped with three MICs, one of which is located at the bottom of the phone and is usually called the main MIC, one is located at the top of the phone and is called the secondary MIC, and the other is located at the back of the phone and is called the third MIC or back MIC. By setting up three MICs, the noise reduction effect of the phone can be improved and the sound quality of the phone can be improved.

[0059] In addition, if the MIC is set on the back of the terminal device, the stacking design of the MIC can be divided into a hard board solution and a flexible board solution according to the material of the circuit board on which the MIC is soldered. Among them, the hard board solution refers to the solution in which the MIC is soldered on a hard circuit board. The structural diagram of this solution can be shown as follows Figure 2 See Figure 2 In the hard board solution, the MIC 210 is welded on the hard circuit board 220 , and the hard circuit board 220 is provided with an opening, and the hard circuit board and the appearance structure 230 of the terminal device are sealed by a seal 240 .

[0060] The flexible board solution refers to a solution in which the MIC is arranged on a flexible circuit board. The structural diagram of this solution can be shown as follows: Figure 1 In this solution, the MIC is arranged on a flexible circuit board. When the whole machine is assembled, the flexible circuit board with the MIC is usually bonded to the lower surface of the bracket of the terminal device, so that the flexible circuit board with the MIC is installed in the whole machine together with the bracket.

[0061] Furthermore, in the flexible board solution, there is a risk that the MIC will fall off the bracket. For example, due to the bending property of the flexible circuit board, the MIC can fall off the bracket after multiple bending. Alternatively, as the usage time increases, the adhesive strength of the backing bonding the flexible circuit board and the bracket decreases, which may also cause the MIC and the flexible circuit board to fall off the bracket.

[0062] To reduce the risk of MIC shedding, see Figure 1 At present, a support member for supporting the MIC is usually provided under the MIC. However, if the support member is provided under the MIC, a space needs to be reserved for the support member in the terminal device.

[0063] In view of the problem that in the existing flexible board solution, in order to reduce the risk of MIC falling off, a support member needs to be provided for the MIC, resulting in the terminal device needing to reserve space for the support member, the present application provides an audio device and a terminal device including the audio device. The audio device can not only reduce the risk of MIC falling off, but also does not need to provide a support member.

[0064] The terminal device 1 in the embodiment of the present application can be called user equipment (UE), terminal, terminal device, etc. For example, the terminal device 1 can be a tablet computer (portable android device, PAD), a personal digital assistant (personal digital assistant, PDA), a laptop computer, a handheld device with wireless communication function, a computing device, a vehicle-mounted device, a wearable device, a virtual reality (virtual reality, VR) terminal device, an augmented reality (augmented reality, AR) terminal device, a wireless terminal in industrial control (industrial control), a wireless terminal in self driving, a wireless terminal in remote medical, a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (transportation safety), a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), etc., which are mobile terminals or fixed terminals with display screens. In the embodiment of the present application, the form of the terminal device is not specifically limited.

[0065] Figure 3 The structure of the terminal device 1 of an embodiment is schematically shown. Figure 3 As shown, in the embodiment of the present application, the terminal device 3 is taken as a handheld device with a wireless communication function as an example for explanation, and the handheld device can be a mobile phone, etc. Figure 3In the figure, the short side of the mobile phone is the x-axis of the coordinate system, and the side where the height of the mobile phone is located is the y-axis of the coordinate system.

[0066] Figure 4 The partial decomposition structure of a terminal device of an embodiment is schematically shown. Figure 3 and Figure 4 As shown, the terminal device of the embodiment of the present application includes a structural part 2, a decorative part 3, a microphone 4, a flexible circuit board 5, a bracket 6, a mainboard 7, a middle frame 8 and a screen assembly 9. In addition, it may also include a battery assembly and various types of electronic components. In addition, Figure 4 In the coordinate system shown, the short side of the terminal device is the x-axis of the coordinate system, the side where the height of the terminal device is located is the y-axis of the coordinate system, and the long side of the terminal device is the z-axis of the coordinate system.

[0067] Among them, the screen assembly 9 is installed on the middle frame 8, and the display area of ​​the screen assembly 9 is exposed to present image information to the user. The mainboard 7 and the battery assembly are arranged in the terminal device 1, and are located on the inner side of the structural member 2 and the screen assembly 9, so that the user cannot easily observe the mainboard 7 and the battery assembly outside the terminal device 1. The electronic components are arranged on the mainboard 7. The electronic components include but are not limited to processors, antenna modules, Bluetooth modules, wireless communication modules, global positioning system (GPS) modules, power and charging modules, screen display and operation modules, distance sensors, light sensors, headphone interfaces and universal serial bus (USB) interfaces.

[0068] In addition, in a feasible design, the structural member 2 may be a cover or a shell of a terminal device. For example, if the terminal device is a mobile phone, the structural member 2 may be a battery cover of the mobile phone.

[0069] Since the internal space of the terminal device 1 is relatively small, the electronic components are usually highly integrated on the main board 7 to fully reduce the volume of the main board 7 and reduce the space occupancy rate of the main board 7. Optionally, in order to meet the design requirements of the internal space of the terminal device 1, the main board 7 can also adopt a split design. Different electronic components are arranged on the split main board 7 to realize corresponding functions.

[0070] The battery assembly is used to provide power to the terminal device 1 to ensure the normal operation of the terminal device 1. For example, the battery assembly can provide power to the screen assembly 9 so that the screen assembly 9 displays image information or completes corresponding operation instructions, or the battery assembly can provide power to the mainboard 7 to ensure that the electronic components on the mainboard 7 work normally.

[0071] The battery assembly includes a battery and a battery protection circuit board. The battery can be a lithium-ion battery, such as a lithium iron phosphate battery. The battery is a structural component that can convert chemical energy into electrical energy. The battery includes a positive electrode ear and a negative electrode ear with opposite polarities.

[0072] The battery protection circuit board is arranged on one side of the battery along the height direction Y of the structural member. The battery protection circuit board is a plate-like structure with a predetermined thickness. The battery protection circuit board detects the working state of the battery and reduces the possibility of overcharging, overdischarging, short circuit or ultra-high temperature charging and discharging of the battery, thereby protecting the battery. The battery protection circuit board includes a protection circuit. The positive and negative ears of the battery can be welded to the protection circuit respectively, thereby realizing the electrical connection between the battery and the battery protection circuit board.

[0073] As one of the products with high frequency of daily use, the terminal device 1 has an increasing demand from users for thinning or miniaturization of the terminal device 1. Thinning or miniaturization of the terminal device 1 can effectively reduce the fatigue and carrying difficulty of the user when using the terminal device 1. At the same time, the user also has more requirements for the functions of the terminal device 1. For example, the terminal device 1 can include functional devices for taking pictures, photosensitizing or lighting, so that the terminal device 1 can realize multiple functions. Taking the functional device as a camera module for taking pictures as an example, in order to obtain better imaging quality, the size of the camera module needs to be designed to be larger to set up an optical lens group or optical sensor with better performance. However, a camera module with a larger size will limit the thickness of the terminal device 1. In order to achieve thinning or miniaturization of the terminal device 1 and also obtain good imaging quality, it is necessary to set a decorative part 3 for shielding or disguising the functional device on the structural part of the terminal device 1, so as to take into account the appearance of the terminal device 1 while using the functional device to realize the corresponding function, and also to design the thickness of the part other than the functional device to be smaller, so as to achieve thinning or miniaturization of the terminal device 1. The decorative part 3 is arranged on the structural part and can be connected to the structural part. Since a portion of the decorative element 3 is higher than the outer surface of the structural element, the overall thickness of the area where the decorative element is set on the terminal device 1 is relatively large. The outer surface of the structural element refers to the surface facing the external environment. When using the terminal device 1, the user can observe or touch the outer surface of the structural element.

[0074] Also, see Figure 4 In the terminal device, a microphone 4, a flexible circuit board 5 and a bracket 6 constitute an audio device of the terminal device, wherein the microphone 4 is located between the bracket 6 and the flexible circuit board 5, and the area where the flexible circuit board contacts the microphone includes a first opening, and the first opening is used for circulating the airflow of the audio.

[0075] Since the microphone 4 is located between the bracket 6 and the flexible circuit board 5, the bracket 6 can play a supporting role, thereby reducing the risk of the microphone 4 falling off the bracket, and the audio device does not need to be provided with a support, which solves the problem of the need to reserve additional space for the terminal device due to the need to provide a support in the prior art. Moreover, after the audio device is assembled to the terminal device, the airflow of the audio can flow from the outside of the terminal device to the microphone 4 through the first opening.

[0076] Furthermore, the terminal device 1 may also include: a first reinforcement 10, a second reinforcement 11, a sealant 12 and an adhesive 13. The first reinforcement 10 and the second reinforcement 11 may be used to improve the strength of the audio device, wherein the first reinforcement 10 is located between the bracket and the flexible circuit board, and is located around the microphone. The second reinforcement 11 is located between the flexible circuit board 5 and the sealant 12. The sealant 12 is used to seal the flexible circuit board 5 and the structural parts of the terminal device. The adhesive 13 may be used to bond the first reinforcement 10 to the bracket 6, and to bond the first reinforcement 10 to the flexible circuit board 5, and the adhesive 13 may also be used to bond the second reinforcement 11 to the flexible circuit board 5, and to bond the second reinforcement 11 to the sealant.

[0077] In order to clarify the solution provided by the present application, the solution provided by the present application is introduced and explained through various embodiments in conjunction with the accompanying drawings.

[0078] The present application embodiment provides an audio device. Figure 5 The audio device includes: a microphone 4, a flexible circuit board 5 and a bracket 6.

[0079] The microphone 4 is located between the bracket 6 and the flexible circuit board 5. In a feasible design, the bracket 6 can be a mainboard bracket of the terminal device.

[0080] In addition, the area where the flexible circuit board 5 contacts the microphone 4 includes a first opening, and the first opening is used to circulate the airflow of the audio. After the audio device is assembled into the terminal device, the airflow of the audio can flow from the structural component of the terminal device to the microphone 4 through the first opening, so that the microphone 4 receives the airflow of the audio.

[0081] Since the microphone 4 is located between the bracket 6 and the flexible circuit board 5 in the audio device, and the bracket 6 can play a supporting role, the risk of the microphone 4 falling off the bracket 6 can be reduced in the case where no supporting member is provided, thereby solving the problem in the prior art that the terminal device needs to reserve additional space for the supporting member due to the need to provide the supporting member. In addition, since the solution of the present application does not require the terminal device to reserve space for the supporting member, the terminal device can be made thinner and lighter.

[0082] For further information, see Figure 6 The audio device provided in the embodiment of the present application further includes: a first reinforcing member 10. The first reinforcing member 10 is located between the bracket 6 and the flexible circuit board 5, and is located around the microphone 4. Exemplarily, the first reinforcing member 10 may surround the microphone 4.

[0083] The first reinforcing member 10 can be connected to the bracket 6 in a variety of ways. For example, in a feasible design, the first side of the first reinforcing member 10 is welded to the bracket 6, or, in another feasible design, the first side of the first reinforcing member 10 is bonded to the bracket 6 by the adhesive 13. Of course, the first reinforcing member 10 can also be connected to the bracket 6 in other ways, which is not limited in the embodiment of the present application.

[0084] In addition, the first reinforcing member 10 can also be connected to the flexible circuit board 5 in a variety of ways. For example, in a feasible design, the second side of the first reinforcing member 10 is welded to the flexible circuit board 5, or, in another feasible design, the second side of the first reinforcing member 10 is bonded to the flexible circuit board 5 by the adhesive 13. Among them, the first side of the first reinforcing member 10 is opposite to the second side of the first reinforcing member 10. Of course, the first reinforcing member 10 can also be connected to the flexible circuit board 5 in other ways, and the embodiment of the present application is not limited to this.

[0085] The first reinforcing member 10 can be used to enhance the strength of the audio device. The first reinforcing member 10 can include a metal member, such as a steel sheet, or the first reinforcing member 10 can include a fiber composite member. Of course, the first reinforcing member 10 can also include other devices that can enhance the strength of the audio device, which is not limited in the present embodiment of the application.

[0086] The audio device provided in the embodiment of the present application also includes: a sealing member 12.

[0087] When the audio device is disposed in the terminal device, the flexible circuit board 5 and the structural member of the terminal device are sealed by the seal 12. The structural member may be a cover or a housing of the terminal device, for example, if the terminal device is a mobile phone, the structural member may be a battery cover or a mobile phone case of the mobile phone.

[0088] In addition, the seal 12 includes a second opening for circulating the airflow of the audio. Typically, the center line of the second opening may be the same as the center line of the first opening. The second opening and the first opening form an airflow channel so that the airflow of the audio flows into the microphone 4.

[0089] The sealing member 12 may include foam and / or adhesive. Of course, the sealing member 12 may also be made of other materials with sealing function, which is not limited in the embodiment of the present application.

[0090] Furthermore, the audio device provided in the embodiment of the present application also includes: a second reinforcement member 11.

[0091] The second reinforcing member 11 is located between the flexible circuit board 5 and the sealing member 12. In addition, the second reinforcing member 11 includes a third opening, which can be used for the airflow of the audio.

[0092] The first opening, the second opening, and the third opening form an airflow channel, and when the audio device is set in the terminal device, the airflow of the audio can flow through the airflow channel from the structural component of the terminal device to the microphone 4. In a feasible design, the center lines of the first opening, the second opening, and the third opening are located in the same straight line.

[0093] The second reinforcing member 11 can be connected to the flexible circuit board 5 in a variety of ways. For example, in a feasible design, the first side of the second reinforcing member 11 is welded to the flexible circuit board 5, or, in another feasible design, the first side of the second reinforcing member 11 is bonded to the flexible circuit board 5 through the adhesive 13. Of course, the second reinforcing member 11 can also be connected to the flexible circuit board 5 in other ways, which is not limited in the embodiment of the present application.

[0094] In addition, the second reinforcing member 11 can be connected to the sealing member 12 in a variety of ways. For example, in a feasible design, the second side of the second reinforcing member 11 is welded to the sealing member 12, or, in another feasible design, the second side of the second reinforcing member 11 is bonded to the sealing member 12 via the adhesive 13. The first side of the second reinforcing member 11 is opposite to the second side of the second reinforcing member 11. Of course, the second reinforcing member 11 can also be connected to the sealing member 12 in other ways, which is not limited in the embodiment of the present application.

[0095] The second reinforcing member 11 can also be used to enhance the strength of the audio device. In addition, the second reinforcing member 11 can include a metal member, such as a steel sheet, or the second reinforcing member 11 can include a fiber composite member. Of course, the second reinforcing member 11 can also include other devices that can enhance the strength of the audio device, and the embodiment of the present application is not limited to this.

[0096] In a feasible design of an embodiment of the present application, the first surface of the flexible circuit board 5 covers the surface of the second side of the first reinforcement 10, wherein the first surface of the flexible circuit board 5 is the surface where the flexible circuit board 5 is connected to the first reinforcement 10, and the surface of the second side of the first reinforcement 10 is the surface where the first reinforcement 10 is connected to the flexible circuit board 5.

[0097] In this solution, the first surface of the flexible circuit board 5 covers the surface of the second side of the first reinforcing member 10, that is, the area of ​​the surface of the flexible circuit board 5 connected to the first reinforcing member 10 is larger than the area of ​​the surface of the second side of the first reinforcing member 10. The flexible circuit board 5 has a bendable property. During the use of the terminal device, the flexible circuit board 5 can be bent according to user needs, and the first surface of the flexible circuit board 5 covers the surface of the second side of the first reinforcing member 10, which can prevent the first reinforcing member 10 from affecting the bending of the flexible circuit board 5.

[0098] In addition, in another feasible design of the embodiment of the present application, the second surface of the flexible circuit board 5 covers the surface of the first side of the second reinforcement 11, wherein the second surface of the flexible circuit board 5 is the surface where the flexible circuit board 5 is connected to the first reinforcement 10, and the surface of the first side of the second reinforcement 11 is the surface where the second reinforcement 11 is connected to the flexible circuit board 5.

[0099] In this solution, the second surface of the flexible circuit board 5 covers the surface of the first side of the second reinforcement 11, that is, the area of ​​the surface where the flexible circuit board 5 is connected to the second reinforcement 11 is larger than the area of ​​the surface of the first side of the second reinforcement 11, thereby preventing the second reinforcement 11 from affecting the bending of the flexible circuit board 5.

[0100] In the audio device provided in the embodiment of the present application, the microphone 4 is located between the flexible circuit board 5 and the bracket 6. In a feasible design, the surface of the bracket 6 is a plane, that is, the bracket 6 does not include a groove.

[0101] Or, in another possible design, see Figure 7 As shown in the structural diagram, the bracket 6 includes a groove, and the microphone 4 is located in the groove.

[0102] Among them, since the microphone 4 is located in the groove of the bracket 6, the height of the audio device can be reduced, and the space occupied by the audio device can be further reduced, which is conducive to improving the lightness and thinness of the terminal device.

[0103] Depending on the type and volume of the terminal device, the depth range of the groove included in the bracket 6 is different. If the terminal device is a mobile phone, in a feasible design, the depth of the groove can be 0.5mm-1.5mm. In one example, the depth of the groove is 0.5mm, or in another example, the depth of the groove is 1.5mm.

[0104] In addition, if the bracket 6 includes a groove, the bottom of the microphone 4 may be in contact with the groove, or there may be a gap between the bottom of the microphone 4 and the groove. In this case, if the terminal device is a mobile phone, the distance between the bottom of the microphone 4 and the groove may be 0.05 mm-0.25 mm. In one example, the distance between the bottom of the microphone 4 and the groove is 0.05 mm, or in another example, the distance between the bottom of the microphone 4 and the groove is 0.25 mm.

[0105] In another embodiment of the present application, a terminal device is provided, which includes the audio device disclosed in the above embodiments.

[0106] The terminal device does not need to provide a support for the microphone for the audio device, so there is no need to reserve space for the support. Compared with the existing terminal devices, the terminal device provided by the embodiment of the present application can be lighter and thinner.

[0107] Furthermore, in the solution provided in the embodiment of the present application, the screen of the terminal device may be a flexible screen, which may include a single-curved screen, a double-curved screen, a triple-curved screen, a quad-curved screen, a straight screen, a folding screen and a hinge screen, etc., which is not limited in the embodiment of the present application.

[0108] The same or similar parts between the various embodiments of this specification can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the device and system embodiments, since they are basically similar to the method embodiments, the description is relatively simple, and the relevant parts can be referred to the description of the method embodiment part.
