Therefore, the current form of simply opening a plurality of data interfaces on the frame of the smart tablet has been difficult to meet the current use requirements, and the convenience of use needs to be improved.

[0080] To solve the above technical problems, the application provides a microphone assembly and an electronic device. The microphone assembly and the electronic device provided by the application are described in detail below with reference to the accompanying drawings.

[0081] Referring to Figures 1 to 3 The electronic device 200 provided by the application includes but is not limited to a smart interactive tablet, a display, a television, a tablet device, a mobile phone, a camera, and a smart blackboard. The electronic device 200 includes a device shell and a main circuit board, and the main circuit board is fixedly connected to the device shell. The main circuit board can be arranged inside the device shell or arranged outside the device shell as an independent unit.

[0082] Referring to Figure 4 and Figure 5 In the application, the electronic device 200 further includes a microphone assembly 100. The microphone assembly 100 includes a mounting bracket 1, a microphone assembly 2, and a terminal assembly 3. Referring to Figure 3 and Figure 4 The electronic device 200 is formed with a mounting cavity 201 and a sound pickup hole 202 that communicates the mounting cavity 201 with the outside. The mounting cavity 201 can provide a mounting space for the microphone assembly 2, and external sound can enter the mounting cavity 201 through the sound pickup hole 202 and be collected by the microphone assembly 2. The microphone assembly 2 is arranged on one side of the mounting bracket 1, and the terminal assembly 3 is arranged on the other side of the mounting bracket 1. Taking the display as an example, with respect to a user, the microphone assembly 2 and the terminal assembly 3 in the microphone assembly 100 mounted on the display can be arranged in front and back.

[0083] The mounting bracket 1 is connected to the electronic device 200 and arranges the microphone assembly 2 in the mounting cavity 201, and the microphone assembly 2 picks up external sound through the sound pickup hole 202. Exemplarily, the device shell of the electronic device 200 can form the mounting cavity 201, and the sound pickup hole 202 is formed in the cavity wall of the mounting cavity 201, and the microphone assembly 2 is arranged in the mounting cavity 201 in whole or in part corresponding to the sound pickup hole 202, and the mounting bracket 1 can be fixedly connected to the device shell by screw connection, clamping, or the like. The mounting bracket 1 can be fixedly connected to the device shell. For the device shell with a frame structure, the mounting bracket 1 can be mounted on the frame structure. Referring to Figure 4 The mounting bracket 1 is located between the microphone assembly 2 and the terminal assembly 3. The microphone assembly 2 located at the front side can realize high-quality sound collection, and the terminal assembly 3 located at the back side can be better hidden, which is beneficial to improve the appearance of the display. In consideration of further improving the appearance of the display, a decorative cover can be further arranged in front of the microphone assembly 2.

[0084] The terminal assembly 3 can be electrically connected with the microphone assembly 2.

The terminal pins 32 can be USB (Universal Serial Bus) interfaces, including Type-A interfaces, Type-B interfaces, Type-C interfaces, Mini USBs, Micro USBs, and the like. In addition, the terminal pins 32 can also be other audio interfaces, and the types of the audio interfaces are various, and a designer can flexibly select according to requirements, and the application does not make a detailed description here.

[0085] The number of the plurality of terminal pins 32 can be two, three, four, five, or the like. When the number of the terminal pins 32 is only two, the plug interfaces of the two terminal pins 32 are different in direction, for example, the plug interface of one terminal pin 32 can be rearward, and the plug interface of the other terminal pin 32 can be upward along the height direction of the microphone assembly 100.

[0086] When the number of the terminal pins 32 is three, the plug interfaces of two terminal pins 32 can be the same in direction or different in direction, and the plug interface of the other terminal pin 32 is different in direction from the plug interfaces of the two terminal pins 32. For example, the plug interfaces of the two terminal pins 32 can be both rearward, and the plug interface of the other terminal pin 32 can be upward along the height direction of the microphone assembly 100; for another example, referring to FIG. 2, the plug interfaces of the three terminal pins 32 can be all different in direction, the plug interface of one terminal pin 32 of the two terminal pins 32 can be rearward, the plug interface of the other terminal pin 32 can be leftward, and the plug interface of the other terminal pin 32 can be upward along the height direction of the microphone assembly 100, that is, the plug interfaces of the three terminal pins 32 are perpendicular to each other. Figure 4

[0087] When the number of the terminal pins 32 exceeds three, under the premise that the plug interfaces of at least two terminal pins 32 are different in direction, a designer can flexibly set the directions of the plug interfaces of the terminal pins 32 according to actual needs and in reference to the setting modes of the directions of the two terminal pins 32 and the three terminal pins 32, and the application does not make a detailed description here.

[0103] The guide hole 2112 of the driving plate 211 and the one end of the connecting piece 14 away from the bracket body 11 can be connected in a clamping manner or the like. Referring to Figure 9 and Figure 10The connector 14 may include a connected limiting section 141 and a connecting section 142. The end of the limiting section 141 is fixedly connected to the bracket body 11, and the limiting section 141 passes through the clearance hole 220 and the guide hole 2112. A snap-fit ​​structure 1421 is formed on the outer periphery of the end of the connecting section 142, and the snap-fit ​​structure 1421 snaps into the guide hole 2112. The limiting section 141 may be a protruding structure with an outer dimension larger than the inner diameter of the guide hole 2112, such as... Figure 10 As shown, the limiting segment 141 may include a cylinder and multiple protruding ridges extending from the outer periphery of the cylinder. See also Figure 10 The connecting segment 142 may include two spaced elastic portions, one of which protrudes outward to form a snap-fit ​​structure 1421. When the connecting segment 142 passes through the guide hole 2112, the snap-fit ​​structure 1421 is squeezed by the hole wall of the guide hole 2112, causing the elastic portion to deform inward. When the snap-fit ​​structure 1421 extends out of the guide hole 2112, the elastic portion recovers, and at this time, the snap-fit ​​structure 1421 can snap with the end face of the guide hole 2112. In actual manufacturing, the connecting part 14 can be integrally formed by injection molding or other methods, or the connecting segment 142 can be formed by increasing or decreasing the material. For example, a protruding ridge can be fixed on the outer periphery of the cylinder to form a limiting segment 141, an outwardly protruding snap-fit ​​structure 1421 can be provided on the outer periphery of the end of the cylinder, and a notch can be opened along the axis of the cylinder to form the connecting segment 142.

[0104] A buffer 22 is disposed between the microphone circuit board 21 and the bracket body 11, and the buffer 22 has a clearance hole 220 corresponding to the connector 14. The buffer 22 is used to prevent the microphone circuit board 21 from directly contacting the mounting bracket 1, to prevent external vibrations from being transmitted to the microphone circuit board 21, and to reduce the noise transmitted to the microphone circuit board 21. In order to reduce the cost of the buffer 22, in addition to round holes, the clearance hole 220 can also be a rectangular hole, and the size of the clearance hole 220 can be set to be larger, thereby reducing the material consumption for processing the buffer 22. For the microphone circuit board 21 with the connector 213 in the middle, in order to avoid the connector 213, two shorter buffers 22 can be provided, and the two buffers 22 are placed on both sides of the connector 213 during installation.

[0105] The mounting plate 23 is arranged on the side of the microphone circuit board 21 away from the support body 11, and the mounting plate 23 is provided with an audio inlet hole 231 corresponding to the audio transmission hole 2111. The audio inlet hole 231 is in communication with the audio pickup hole 202 and the audio transmission hole 2111. The mounting plate 23 can be fixed on the side of the microphone circuit board 21 away from the support body 11 by means of adhesion or the like. External sound can be transmitted to the microphone 212 through the audio inlet hole 231 of the mounting plate 23 and the audio transmission hole 2111 on the driving plate 211. The buffer 22 and the mounting plate 23 can be made of a material capable of buffering and sealing, such as silicone, rubber, foam, or the like. For example, the buffer 22 can be made of silicone, and the mounting plate 23 can be made of foam. The mounting plate 23 and the buffer 22 cooperate to seal the microphone 212, effectively improving the sound pickup effect of the microphone 212.

[0106] When installing the microphone assembly 2, first, the buffer 22 is sleeved on the connecting piece 14, then the guide hole 2112 of the driving plate 211 of the microphone circuit board 21 is sleeved on the connecting piece 14 and is pressed tightly against the driving plate, so that the guide hole 2112 is connected to the connecting piece 14 in a clamping manner, and finally the mounting plate 23 is adhered to the side of the microphone circuit board 21 away from the support body 11.

[0107] Referring to Figure 11 , in order to further improve the sealing performance of the microphone 212, in some embodiments, the buffer 22 can include a body part 221 and a sealing part 222. The avoiding hole 220 is arranged on the body part 221. The sealing part 222 is arranged on the side of the body part 221 close to the driving plate 211. The sealing part 222 corresponds to the microphone 212 and is provided with a groove 2221 for accommodating the microphone 212. The end face of the sealing part 222 surrounds the microphone 212 and is in close contact with the surface of the driving plate 211. When the sealing part 222 is arranged on the microphone 212, the microphone 212 is located in the groove 2221, and the end face of the sealing part 222 is tightly pressed around the microphone 212, which effectively seals the microphone 212 and ensures the air tightness of the microphone 212, thereby improving the sound pickup effect of the microphone 212.

[0108] Referring to Figure 9 , Figure 10 and Figure 11 , in order to further improve the sound pickup effect of the microphone 212, in some embodiments, the mounting support 1 can include a protruding part 15. The protruding part 15 is fixedly arranged on the side of the support body 11 away from the terminal assembly 3. The protruding part 15 has a ring structure. The end face of the protruding part 15 abuts against the side of the body part 221 away from the driving plate 211, and the orthogonal projection of the protruding part 15 on the driving plate 211 surrounds the microphone 212.

[0109] The protrusion 15 can be a hollow annular structure. The orthographic projection of the protrusion 15 on the driving plate 211 surrounds the microphone 212, in other words, the outer contour of the protrusion 15 can coincide with or be slightly larger than the outer contour of the sealing member 222. The protrusion 15 protrudes from the surface of the mounting bracket 1, when the driving plate 211 is pressed and the end of the connecting member 14 away from the bracket body 11 is clamped with the guide hole 2112 of the driving plate 211, the protrusion 15 mainly exerts pressure on the groove side wall of the groove 2221 of the sealing member 222, but not on the groove bottom wall of the groove 2221. In this way, the protrusion 15 can increase the pressure on the sealing member 222, so that the sealing member 222 is tightly fitted around the microphone 212, improving the sealing performance of the microphone 212, and also avoiding the groove bottom wall of the groove 2221 being concave to contact or even damage the microphone 212, further improving the pickup effect and reliability of the microphone 212.
