Microphones integrated using MEMS (Micro Electro Mechanical System) technology have begun to be mass-produced and applied to various electronic products. Their package size is smaller than that of traditional microphones, making them popular with most microphone manufacturers.

[0003] Currently, in the application of complete devices on the client side, for microphones of different sizes and installation requirements, it is usually necessary to set up a limiting cavity or housing structure within the overall device housing to accommodate the microphone, and then confine the microphone unit within the corresponding structure and make it conductive to the overall device circuit board. However, the existing unit installation method not only places high demands on the overall device housing, but also makes the unit installation and electrical connection operations complex. Furthermore, the overall device housing structure can lead to a large microphone acoustic cavity length, thus affecting wideband audio quality.

[0004] Therefore, simplifying the installation method between the microphone unit and the whole machine, and shortening the acoustic cavity length of the microphone unit are technical problems that urgently need to be solved. Utility Model Content

Therefore, they should not be construed as limitations on the content or structure of this utility model.

[0024] To address the problems of complex installation methods and large microphone cavity lengths affecting wideband audio performance in existing microphone units, this invention provides a microphone module. The module includes an electrical connector that electrically connects the microphone unit to the overall circuit board. The connector includes at least two pins and auxiliary components mounted on the pins. These auxiliary components isolate and position the pins, simplifying pin application and improving overall structural strength. Compared to a single-shell installation method, this module also shortens the microphone cavity length, reduces the front cavity volume, and improves acoustic performance.

[0025] To describe in detail the structure of the microphone module and electronic device of this utility model, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Figures 1 to 5 Schematic structures of microphone modules according to various embodiments of the present invention are shown from different angles; Figure 6 and Figure 7 A schematic structure of an electrical connector according to multiple embodiments is shown.

[0027] like Figures 1 to 7As shown in the figure, the microphone module of this utility model embodiment includes a microphone unit 1 and an electrical connector connecting the microphone unit 1 to the external circuit board 4. The electrical connector includes at least two pins 2 and an auxiliary component 3 disposed on all pins 2. The auxiliary component 3 can isolate and position each pin 2 and enhance the overall structural strength of each pin 2, ensuring the positional accuracy of the pins 2 when assembling the microphone module with the whole machine. This allows the microphone unit 1 to be easily fixed on the circuit board 4. One end of the pin 2 is connected to the microphone unit 1 and the other end of the pin 2 is connected to the circuit board 4. This not only simplifies the application of the microphone unit 1 on the whole machine, but also reduces the installation requirements of the whole machine, effectively shortens the length of the microphone cavity, reduces the front cavity volume, and improves acoustic performance.

[0028] The auxiliary component 3 can be an elastic insulating part, including a long strip-shaped main body and limiting holes set on the main body. The number of limiting holes corresponds to the number of pins 2. Before the microphone unit 1 is installed, each pin 2 can be inserted into the corresponding limiting hole. The auxiliary component 3 helps each pin 2 to be pre-positioned. Then, multiple pins 2 can be soldered one by one at a time, avoiding the efficiency and inconsistency problems caused by soldering each pin 2 independently.

[0029] Specifically, the installation method of microphone unit 1 can be selected according to the overall structural flexibility. For example, the lower surface of microphone unit 1 can be fixed to the circuit board 4 of the whole machine by adhesive or other methods. In this case, the setting direction of microphone unit 1 is parallel to the circuit board 4 of the whole machine. Figure 2 As shown, the sound hole 11 of the microphone unit 1 is located on the side away from the circuit board 4. At this time, the pin 2 can be set as an L-shaped structure, with one end directly attached to the microphone unit 1 for conduction and the other end connected to the circuit board 4 for conduction. This structure can shorten the front cavity length, reduce the front cavity volume, and improve the recording quality.

[0030] To ensure the reliability of the pin 2 connection, while the auxiliary component 3 isolates and positions each pin 2, a soldering groove 41 corresponding to the number of pins 2 can be set on the circuit board 4. A bent soldering part 23 is set at the end of the pin 2 that connects to the circuit board. The soldering part 23 is soldered and fixed in the corresponding soldering groove 41 to increase the contact and soldering area and ensure the reliability of connection and signal transmission.

[0031] In another embodiment, due to limitations in the internal structure of the device or limitations in the sound output direction, the side of the microphone unit 1 can be attached to the circuit board 4 of the device, and the orientation of the microphone unit 1 is perpendicular to the circuit board 4. Figure 3 and Figure 4In this second embodiment, the microphone unit 1 can be used only in the narrow bezel design of the whole machine. The microphone unit 1 can greatly shorten the front cavity length and reduce the front cavity volume by entering sound from the side, thereby achieving a wideband recording effect.

[0032] Furthermore, in the above embodiments, pin 2 can be in the form of an "L" shape or a "C" shape, for example... Figures 1 to 4 In the illustrated embodiment, pin 2 has an L-shaped structure. Figure 5 In the embodiment shown, pin 2 has a C-shaped structure. The specific pin structure can be flexibly set according to the overall structure and welding requirements. To ensure the reliability and convenience of welding, each pin can be limited by the auxiliary component 3 to form the overall structure of the auxiliary component 3 and pin 2. A bending structure can be selectively set at the end of pin 2 to increase the welding area between pin 2 and microphone unit 1 and / or the whole circuit board 4.

[0033] To achieve flexible connection between the microphone unit 1 and the circuit board 4, allowing them to be positioned at various angles, in one specific embodiment of this invention, pin 2 can be configured to include a first pin 21 connected to the microphone unit 1 and a second pin 22 connected to the circuit board 4. Meanwhile, auxiliary component 3 includes a first connector 31 disposed at the end of the first pin 21 and a second connector 32 disposed at the end of the second pin 22. The first pin 21 and the second pin 22 are connected and connected through the first connector 31 and the second connector 32.

[0034] Specifically, the first connector 31 and the second connector 32 can be flexible structural components, and the angle between them can be bent arbitrarily. In the application process, one end of the first pin 21 is connected to the microphone unit 1, and one end of the second pin 22 is connected to the circuit board 4. Then, the first connector 31 and the second connector 32 are plugged in to realize the conduction of the first pin 21 and the second pin 22, thereby completing the assembly and application of the microphone unit 1 and the circuit board 4.

[0035] It is known that the first connector 31 and the second connector 32 can be bent and shaped, thereby adjusting the relative position of the first pin 21 and the second pin 22, making the microphone unit 1 suitable for whole products in various scenarios or installation conditions, and improving the flexibility and convenience of the microphone unit 1 application.

[0036] Corresponding to the microphone module described above, this utility model also provides an electronic device, including a circuit board and the aforementioned microphone module; wherein, the electrical connectors of the microphone module are connected and conductive to the circuit board, making assembly simple, convenient, and efficient. It should be noted that the embodiments of the above electronic device can be referred to the description in the microphone module embodiments; other details will not be repeated here.

[0037] According to the aforementioned microphone module and electronic device, the microphone unit is connected to the external circuit board via an electrical connector. The electrical connector, as an integral structure, may include at least two pins and auxiliary components mounted on the pins. The auxiliary components can pre-isolate and position each pin, thereby simplifying pin soldering and improving the overall structural strength. Compared to the integral housing mounting method, the microphone unit has more flexible and varied application angles on the whole device, and can also effectively shorten the length of the microphone cavity, reduce the front cavity volume, and achieve wideband recording effect.

[0038] The microphone module and electronic device according to the present invention have been described above by way of example with reference to the accompanying drawings. However, those skilled in the art should understand that various modifications can be made to the microphone module and electronic device proposed in the present invention without departing from the scope of the present invention.
