After the user presses the touch key, the triggering device 400 generates a corresponding audio command, the triggering device 400 is electrically connected to the microcontroller 500, and the audio command is transmitted to the microcontroller 500. Microcontroller 500 may be a single chip, and microcontroller 500 serves as a core controller for controlling the operations of the various components of vehicle reminder system 100.

The up and down keys can control volume, and the left and right keys can control different sound effects. Therefore, various functions of the vehicle-mounted prompting system 100 are realized, and the requirements of users are met.

In another embodiment, the triggering device 400 may be a display screen 900 disposed on the console, and may trigger the vehicle system electrically connected to the microcontroller 500 by using a key on the steering wheel 410 or a key on the console as a triggering source, so that the vehicle display screen 900 displays a control interface of the vehicle-mounted reminder system 100, and a user may control the vehicle-mounted reminder system 100 by using a virtual key of the display screen 900. For example, the display 900 displays a fader, which can be slid by a finger of a user to adjust the volume, an upper slider fader to increase the volume, and a lower slider fader to decrease the volume. The information that the user adjusts the volume through the display screen 900 is transmitted to the microcontroller 500, and the microcontroller 500 recognizes and controls the response to the user operation. The user may also cause the speaker 200 to play sound effect files within the automobile system through menu options.
