Description

technical field [0001] The invention relates to a motor vehicle driver examination system, in particular to a vehicle-mounted sound pickup speaker for the motor vehicle driver examination system. Background technique [0002] The pickup and the sound system of the existing motor vehicle driver's test system are independently arranged, and the structure is complicated and there are many wirings. The driving test site needs to collect the voice of the test taker and need to talk to it, which requires two devices: a pickup and a sound system. Now there are improvements to these devices, that is, in the vehicle-mounted equipment of the motor vehicle driver's test system, the pickup and the sound adopt independent modules, but this requires an independent place to install the wiring during the installation process, the volume is large, and the structure is still more complicated. The installation and maintenance period is long and the cost is high. Contents of the invention ...
