Description

Technical Field

[0001] The utility model relates to the technical field of sound input, and more specifically to a vehicle-mounted silicon microphone. Background Art

[0002] With the progress of society and the development of science, hands-free car microphones have been applied to cars. The hands-free car microphone system consists of a Bluetooth module, a car audio system and a car microphone. The car hands-free microphone can realize the driver's wireless call function. The driver can use the hands-free microphone to make hands-free calls while driving, which can improve the driver's safety while driving, free the driver's hands, and let the driver focus on driving the vehicle. Although this type of microphone avoids the defect of the electret microphone that the sensitivity will decrease after long-term use, it is wrapped outside the dustproof net, which is difficult to assemble, and the internal components are easily damaged, affecting the service life of the microphone and the call quality.

[0003] In view of the above problems, regarding the technical problems that the assembly is difficult, the internal components are easily damaged, and the service life of the microphone and the call quality are affected, after a lot of searching, a vehicle-mounted silicon microphone with patent number 201620030859.1 was found, which belongs to the field of sound input. The vehicle-mounted silicon microphone includes a microphone cover, a PCB assembly, and a microphone housing, and the PCB assembly is provided with a rubber sleeve; the utility model, by providing a dustproof net on the rubber sleeve, makes the existing silicon microphone not easy to produce gaps after assembly due to the difficulty of sticking the dustproof net, and affects the call quality. However, the technical solution provided by the patent has the following problems:

[0004] During the installation of the microphone, the microphone shell is assembled with the microphone cover by means of clips, and the microphone assembly is assembled inside the shell and protected by the microphone shell. When the car is bumped, the assembly parts of this clip-on type are prone to loosen up and down when bumped. When the assembly parts become loose, the microphone elements inside are prone to fall out of the shell, causing the microphone to fail to function properly.

[0005] The utility model can prevent the accessories from being loosened easily when bumps occur, and block external dust, making the internal wiring harness and the microphone more stable. Utility Model Content
