DETAILED DESCRIPTION

[0016] The application will be further described below in combination with the drawings and specific embodiments.

[0017] In the embodiment, refer to the drawings Figures 3-6The vehicle roof light assembly integrated with a microphone comprises, in order from top to bottom, a shell 10, a main control circuit board 20, a fixing seat 30, and a panel 50. The fixing seat 30 is fixed with a plurality of functional modules electrically connected with the main control circuit board 20. The types of the functional modules are placed according to needs. In general, keys and lights are necessary in a vehicle roof light, so the key module and the light guide module can be arranged on the fixing seat 30. In the embodiment, the vehicle roof light assembly is integrated with a microphone, so the functional modules further comprise a microphone module 40. The microphone module 40 comprises a microphone circuit board 41, which has two contact ends 411 on the side facing the main control circuit board 20. Two conductive springs 60 are arranged between the main control circuit board 20 and the microphone circuit board 41. The conductive spring 60 comprises a fixed part 61, a deformation part 62, and a contact part 63. The fixed part 61 is used for fixed connection with the main control circuit board 20, usually by soldering process. The contact part 63 is used for contact connection with the contact end 411 of the microphone circuit board 41. When the conductive spring 60 is in a free state, the top of the contact part 63 is higher than the position of the microphone circuit board 41. When the microphone module 40 is fixedly installed on the fixing seat 30, the microphone module 40 exerts pressure on the conductive spring 60 to deform it, so that the conductive spring 60 is in a pressure-deformed state and the contact part 63 is in contact with the contact end 411 of the microphone circuit board 41. The microphone module 40 is connected to the circuit of the main control circuit board 20 through the conductive spring 60.

[0018] Compared with the microphone solution in the background art vehicle roof light, in the vehicle roof light assembly integrated with a microphone of the embodiment, only the functional part in the microphone assembly is retained. The microphone module 40 is fixed by the existing fixing seat 30 and panel 50 in the roof light, and the shell 10 of the microphone assembly is omitted, thereby reducing the cost. In addition, in the embodiment, a special power connection mode is arranged between the microphone circuit board 41 and the main control circuit board 20, i.e. connection through the conductive spring 60, without the need for wire harnesses and connection terminals and other electronic components. Since the conductive spring 60 is a stamping part and is easy to manufacture, the cost of the conductive spring 60 is much lower than that of the wire harnesses and connection terminals and other electronic components. Therefore, not only the material cost and production cost are reduced, but also the assembly efficiency is improved and the labor cost is saved due to the reduction of parts. In addition, it is more important that there is no need to design a special mounting position on the outside of the main control circuit board 20, which saves space and is conducive to the miniaturization design of the microphone.

[0019] Considering that the conductive elastic sheet 60 is stamped, the dimensional tolerance and the shape tolerance of the part after being formed are large, and the fixed part 61 of the conductive elastic sheet 60 is fixed with the main control circuit board 20 through a soldering process, although the position relationship between the two can be ensured through a welding tool, there is still a large position tolerance, so that various factors cause the fitting tolerance between the microphone circuit board 41 and the conductive elastic sheet 60 to be large, specifically, the position of the connecting point of the microphone circuit board 41 and the contact part 63 of the conductive elastic sheet 60 in the contact part 63 of the conductive elastic sheet 60 in different vehicle ceiling lamps will change greatly. In order to ensure the contact fit, the contact part 63 of the conductive elastic sheet 60 in the embodiment is arc-shaped as a whole, and the arc-shaped contact part 63 can ensure that no matter how large the fitting tolerance is, as long as the microphone circuit board 41 can apply force to the conductive elastic sheet 60 to make it in a state of being pressed and deformed, the contact part 63 of the conductive elastic sheet 60 can form a line contact with the microphone circuit board 41; correspondingly, the contact end 411 of the microphone circuit board 41 is rectangular, and the rectangular contact end 411 can adapt to the position change of the line contact.

[0020] In addition, in the embodiment, the width of the contact end 411 of the microphone circuit board 41 is greater than the width of the conductive elastic sheet 60, and for the circuit board, the exposed contact end 411 is generally slightly lower than the solder mask layer, in order to avoid that the contact part 63 of the conductive elastic sheet 60 contacts the solder mask layer and causes poor contact, the width of the contact end 411 of the microphone circuit board 41 needs to be set to be larger.

[0021] The microphone module 40 in the embodiment further includes a microphone function part 42; the panel 50 has a plurality of sound collecting holes 51, the sound collecting holes 51 correspond to the positions of the microphone function part 42, so that the collected sound quality is clearer.

[0022] Although the present application has been described with reference to the preferred embodiments, it should be understood by those skilled in the art that it is not limited to the description of the above embodiments, and various changes in form and details can be made within the scope of the claims.
