Description

Technical Field

[0001] The utility model relates to a vehicle-mounted microphone, more specifically, to a hidden vehicle-mounted microphone. Background Art

[0002] The existing vehicle-mounted microphone assembly basically relies on the shell structure to be exposed outside the roof, and the external decorative cover can be clearly seen, which affects the appearance and has a poor wind noise protection effect. Utility Model Content

[0003] Based on this, it is necessary to provide a hidden vehicle-mounted microphone to address the above technical problems.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A hidden car microphone is characterized in that the hidden car microphone includes a flexible plate body, the flexible plate body is provided with a microphone functional unit, the two side edges of the upper surface of the flexible plate body are provided with a first anti-slip spring sheet, the two side edges of the lower surface of the flexible plate body are provided with a second anti-slip spring sheet, and the two side walls of the flexible plate body are provided with a third anti-slip spring sheet.

[0006] As a preferred embodiment of the present invention, the first anti-slip spring sheet and the second anti-slip spring sheet are both arranged at an angle.

[0007] As a preferred embodiment of the present invention, the inclination angle of the first anti-slip spring sheet and the second anti-slip spring sheet is 60 degrees.

[0008] As a preferred embodiment of the present invention, the flexible board is made of a flexible PCBA.

[0009] As a preferred embodiment of the present invention, the first anti-slip spring sheet, the second anti-slip spring sheet and the third anti-slip spring sheet are made of flexible PCBA.

[0010] As a preferred embodiment of the present invention, the first anti-slip elastic sheet, the second anti-slip elastic sheet and the third anti-slip elastic sheet are made of thin steel sheets.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This utility model provides a concealed vehicle-mounted microphone. When the flexible plate is pushed into position, the first, second, and third anti-slip springs expand and press against the surrounding woven fabric, acting as a check. Even if the wiring harness is pulled, the flexible plate will not shift, thus improving reliability. Because the flexible plate is made of a flexible PCBA, it has good flexibility, ensuring the flexibility of the vehicle roof and enhancing its applicability. Because the concealed vehicle-mounted microphone is completely concealed within the woven fabric of the vehicle roof, it provides excellent wind noise protection. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In order to more clearly illustrate the solutions in the present invention, a brief introduction will be given below to the drawings required for use in the description of the embodiments. Obviously, the drawings described below are some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0019] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0020] like Figures 1 to 3 As shown, the hidden vehicle-mounted microphone includes a flexible plate body 11, on which a microphone functional unit 12 is provided, a first anti-slip spring sheet 13 is provided on both side edges of the upper surface of the flexible plate body 11, a second anti-slip spring sheet 15 is provided on both side edges of the lower surface of the flexible plate body 11, and a third anti-slip spring sheet 14 is provided on both side walls of the flexible plate body 11.

[0021] It should be noted that the first anti-slip spring sheet 13 and the second anti-slip spring sheet 15 are both arranged at an angle.

[0022] The first anti-slip spring sheet 13 and the second anti-slip spring sheet 15 have an inclination angle of 60 degrees.

[0023] In addition, the flexible board 11 is made of a flexible PCBA, such as an FPC (flexible printed circuit board).

[0024] It should be noted that the first anti-slip spring sheet 13, the second anti-slip spring sheet 15 and the third anti-slip spring sheet 14 are made of flexible PCBA. Alternatively, the first anti-slip spring sheet 13, the second anti-slip spring sheet 15 and the third anti-slip spring sheet 14 are made of thin steel sheets.

[0025] The working method of the hidden car microphone is described below.

[0026] like Figure 4 As shown, the user can directly install the hidden car microphone inside the car roof. During the installation process, the flexible plate 11 is pushed into the braid 2 of the car roof against the inclination direction of the first anti-slip spring sheet 13, the second anti-slip spring sheet 15, and the third anti-slip spring sheet 14. Finally, the wiring harness 3 is led out and connected to the control circuit of the car. When the flexible plate 11 is pushed into place, the first anti-slip spring sheet 13, the second anti-slip spring sheet 15, and the third anti-slip spring sheet 14 will open and hold up the surrounding braid 2, acting as a check. Even if the wiring harness 3 is pulled, it will not cause the flexible plate 11 to shift, and the reliability is good. Of course, after the flexible plate 11 is fixed, the user can also apply a little adhesive to further strengthen the fixing effect.

[0027] In addition, since the flexible board 11 is made of a flexible PCBA, it has good flexibility, which can ensure the flexibility of the car roof and has better applicability.

[0028] In addition, since the hidden car microphone is completely concealed in the woven fabric 2 of the car roof, it has an excellent wind noise insulation effect.

[0029] Without limitation to this, any changes or substitutions that are not conceived through creative work should be included in the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be based on the scope of protection defined in the claims.
