Description

Technical Field

[0001] This disclosure relates to the field of electronic product technology, and in particular to a microphone structure and electronic device. Background Technology

[0002] With the rapid development of electronic products, people have higher and higher requirements for the audio effect of electronic products. Usually, a rubber part is set between the microphone module and the shell to seal the microphone module.

[0003] Taking a laptop as an example, the A-shell refers to the back cover of the laptop screen, which is the top of the laptop when closed, and usually has a prominent brand logo; the B-shell refers to the front bezel of the laptop screen, which is the side where the laptop screen is located. The specific solution involves attaching a rubber component to a limiting frame on the B-shell, which then contacts the microphone module located on the A-shell to achieve an airtight connection. However, this structure has a small contact area between the rubber component and the microphone module. Poor assembly and tolerances can lead to poor contact. For example, the rubber component may be misaligned within the limiting frame, causing the holes in the rubber component to cover the microphone module's pickup holes, resulting in poor airtightness and affecting sound reception. Furthermore, the contact between the rubber component and the microphone module is a soft-hard contact, which may result in insufficient contact, affecting airtightness. Utility Model Content

[0004] This disclosure provides a microphone structure and electronic device to at least solve the above-mentioned technical problems existing in the prior art.

[0005] According to a first aspect of this disclosure, a microphone structure is provided, including a microphone module having a pickup hole, and further comprising: a first rubber member sleeved on the microphone module, the first rubber member having a groove, the bottom of the groove having a first through hole communicating with the pickup hole; and a second rubber member including a protrusion, the protrusion being tightly fitted with the groove, the protrusion having a second through hole penetrating the second rubber member, the second through hole and the first through hole communicating with the pickup hole.

[0006] In one embodiment, the first rubber member includes a bottom and four sides extending from the bottom, the bottom and the four sides forming a receiving groove for housing the microphone module, the groove being formed on the side of the bottom away from the microphone module, and the first through hole penetrating the bottom.

[0007] In one embodiment, the protrusion makes interference contact with the groove.

[0008] In one embodiment, the opening of the groove is circular.

[0009] In one embodiment, the inner wall of the groove has an arc surface that smoothly transitions to the bottom of the groove.

[0010] In one embodiment, the protrusion is columnar.

[0011] In one embodiment, the surface of the protrusion that contacts the groove is contoured to the groove.

[0012] In one embodiment, the outer diameter of the protrusion is smaller than the diameter of the groove opening.

[0013] In one embodiment, the difference between the diameter of the groove opening and the outer diameter of the protrusion is greater than 0 and less than or equal to 1 mm.

[0014] According to a second aspect of this disclosure, an electronic device is provided, including a housing assembly and a PCB disposed within the housing assembly. The housing assembly further includes a microphone structure as described in any of the above embodiments. A second rubber member is disposed on the housing assembly, and the microphone module is disposed on the PCB. The first rubber member is adhesively bonded to the PCB.

[0015] In this disclosure, the microphone structure includes a first rubber component and a second rubber component. The first rubber component is fitted onto the microphone module and tightly connected with the second rubber component, changing the original soft-hard contact to a tight contact between the two rubber components. This solves the problem of insufficient contact due to poor assembly of the microphone module and the second rubber component, which affects air tightness. Furthermore, the connection between the first and second rubber components increases the contact area, solving the problem of poor assembly and tolerance affecting air tightness caused by the small contact area in the original direct contact scheme between the microphone module and the second rubber component. In addition, since the groove of the first rubber component and the protrusion of the second rubber component are connected, when the first and second through holes on them are misaligned, an automatic correction function can be performed to maintain the air tightness and preserve the sound reception performance.

[0026] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0027] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0028] Reference Figures 1 to 5As shown, this disclosure discloses an exemplary embodiment of a microphone structure, including a microphone module 3, a first rubber component 1, and a second rubber component 2. The microphone module 3 is provided with a pickup hole 31; the first rubber component 1 is sleeved on the microphone module 3, and the first rubber component 1 is provided with a groove 110, the bottom of which has a first through hole 111, which communicates with the pickup hole 31; the second rubber component 2 includes a protrusion 21, which fits tightly with the groove 110, and the protrusion 21 has a second through hole 22 penetrating through the second rubber component 2. The second through hole 22, the first through hole 111, and the pickup hole 31 are connected and located on the same straight line.

[0029] In this embodiment, the first rubber component 1 wraps around the microphone module 3, with the side of the first rubber component 1 having the groove 110 facing the second rubber component 2 for mating and connection. A first through hole 111 penetrates the first rubber component 1 along its thickness direction, and a second through hole 22 penetrates the second rubber component 2 along its thickness direction. When the second rubber component 2, the first rubber component 1, and the microphone module 3 are all properly assembled in the correct positions to form a seal, the second through hole 22, the first through hole 111, and the pickup hole 31 are connected and located on the same straight line. It should be noted that "sealing" here refers to a tight fit without holes at all connection points except for the second through hole 22, the first through hole 111, and the pickup hole 31, particularly a tight connection between the protrusion 21 and the groove 110. In summary, since the microphone structure includes a first rubber component 1 and a second rubber component 2, the first rubber component 1 is fitted onto the microphone module 3 and tightly connected with the second rubber component 2. This changes the original soft-hard contact to a tight contact between the two rubber components, solving the problem of insufficient contact due to poor assembly of the microphone module 3 and the second rubber component 2, which affects air tightness. Furthermore, the connection between the first rubber component 1 and the second rubber component 2 increases the contact area, solving the problem of poor assembly and tolerance affecting air tightness caused by the small contact area in the original direct contact scheme of the microphone module 3 and the second rubber component 2. In addition, since the groove 110 of the first rubber component 1 and the protrusion 21 of the second rubber component 2 are connected, when the first through hole 111 and the second through hole 22 on both are misaligned, an automatic correction function can be performed to maintain the air tightness and preserve the sound reception performance.

[0030] In one embodiment, the first rubber part 1 is rectangular in shape, including a bottom 11 and four sides 12 extending from the bottom 11. The bottom 11 and the four sides 12 surround to form a receiving groove 121 for fitting the microphone module 3. A groove 110 is formed on the side of the bottom 11 away from the microphone module 3. A first through hole 111 penetrates the bottom 11.

[0031] In this embodiment, the microphone module 3 is typically electrically connected to the printed circuit board in the electronic device through soldering, plugging, or other methods to achieve signal transmission and processing. The first rubber part 1 is an integrally molded structure. The first rubber part 1 and the printed circuit board cover the microphone module 3 in the receiving groove 121. The first rubber part 1 and the printed circuit board are tightly connected by adhesive, preventing system noise inside the electronic device and various external noises from entering the microphone module 3 through the gap between the first rubber part 1 and the printed circuit board, thereby improving the sound reception effect.

[0032] In one embodiment, the protrusion 21 makes interference contact with the groove 110.

[0033] In this embodiment, the protrusion 21 and the groove 110 are in interference contact to ensure a tight connection between the first rubber part 1 and the second rubber part 2 and to prevent relative movement.

[0034] In one embodiment, the opening of the groove 110 is circular.

[0035] Furthermore, in one embodiment, the inner wall of the groove 110 has an arc surface that smoothly transitions to the bottom of the groove.

[0036] In this embodiment, the second through hole 22 on the protrusion 21 of the second rubber part 2 may shift relative to the first through hole 111 at the bottom of the groove 110. By designing the opening and bottom of the groove 110 as circular, with the area of ​​the bottom circle smaller than the area of ​​the opening circle of the groove 110, and connecting the opening and bottom of the groove 110 with a smooth arc surface, when the protrusion 21 of the second rubber part 2 shifts, it will automatically correct itself to the correct position with lower stress due to the different stresses in the groove 110, thus performing an automatic correction function, maintaining airtightness, and ensuring sound reception performance. It is understood that the opening of the groove 110 can also be, but is not limited to, square or elliptical shapes, which will not be elaborated further here.

[0037] Furthermore, in one embodiment, the protrusion 21 is columnar.

[0038] Specifically, in one embodiment, the surface of the protrusion 21 that contacts the groove 110 is contoured to the groove 110.

[0039] In this embodiment, when the opening of the groove 110 is circular, the protrusion 21 is cylindrical in shape; if the opening of the groove 110 is square, the protrusion 21 is square-column shaped. Since the inner wall of the groove 110 is a smooth arc surface transitioning to the bottom of the groove, the protrusion 21 can be rounded, so that the surface of the protrusion 21 that contacts the groove 110 conforms to the shape of the groove 110. This reduces the fitting clearance, improves the fitting accuracy, and ensures a tight connection between the groove 110 and the protrusion 21.

[0040] In one embodiment, the outer diameter of the protrusion 21 is smaller than the diameter of the groove opening of the recess 110.

[0041] Specifically, in one embodiment, the difference between the diameter of the groove opening of the groove 110 and the outer diameter of the protrusion 21 is greater than 0 and less than or equal to 1 mm.

[0042] In this embodiment, the groove 110 on the first rubber part 1 has a circular opening, and the diameter of the groove 110 is 1 mm larger than the outer diameter of the cylindrical protrusion 21 on the second rubber part 2. This ensures that the assembly error is within 1 mm, which can effectively correct the misalignment of the second rubber part 2. It is understood that the 1 mm here is not an absolute 1 mm, and there can be a slight deviation within the tolerance range.

[0043] Air tightness tests were conducted on the original structure and the microphone structure of this disclosure under normal assembly and misaligned assembly conditions using acoustic software. Both the original structure and the structure of this disclosure were tested under conditions capable of isolating sound intensities exceeding 6 dB, thereby reducing the impact of external noise on the internal environment. The test results are shown in Table 1 below:

[0044] Table 1. Results of airtightness test

[0045] Structural conditions Radio reception results airtightness Normal assembly of the original structure 7-8 dB The original structure was misaligned. 2-3dB Poor airtightness The structure disclosed is normally assembled. 8-9 dB The structure of this disclosure is misaligned. 7-8 dB Air tightness can be corrected

[0046] Reference Figure 6 As shown, this disclosure also provides an electronic device, including a housing assembly 4 and a PCB 5 disposed within the housing assembly 4. The housing assembly 4 is further provided with a microphone structure as described in any of the above embodiments. A second rubber component 2 is disposed on the housing assembly 4, a microphone module 3 is disposed on the PCB 5, and a first rubber component 1 is adhesively connected to the PCB 5.

[0047] In this embodiment, the electronic device is a laptop computer. The housing assembly 4 includes a shell 41 (A shell) and a shell 42 (B shell). The second rubber part 2 is attached to the shell 42 (B shell). The PCB 5 is disposed on the shell 41 (A shell). The microphone module 3 is electrically connected to the PCB 5 through soldering, plugging, or other methods to achieve signal transmission and processing. The first rubber part 1 and the PCB 5 enclose the microphone module 3 in the receiving groove 121. The first rubber part 1 and the PCB 5 are tightly connected by adhesive, preventing system noise inside the electronic device and various external noises from entering the microphone module 3 through the gap between the first rubber part 1 and the printed circuit board. This improves the sound reception effect and can also automatically correct itself when the second rubber part 2 is tilted, maintaining an airtight effect and ensuring sound reception performance.
