Problems solved by technology

Or using the touch screen may not be sensitive and convenient when wearing gloves or having liquids on your hands, which does not exist when using traditional function keys
[0004] If you want to safely and conveniently use traditional keys for multimedia control in these scenarios, you need to add traditional function keys to the vehicle. However, the layout of traditional function keys is restricted at the factory, and the vehicle does not reserve enough space. Space to add traditional function keys, and adding traditional function keys to a vehicle that has completed the wiring layout in the vehicle also requires the modification of the wiring inside the vehicle, which is time-consuming and laborious

Abstract

The invention relates to a multimedia control method and device, a function key and a vehicle. The method comprises the steps of: acquiring a sound signal transmitted by the function key, wherein thesound signal is generated in response to the control operation of a user to the function key, with the frequency of the sound signal corresponding to the control operation; converting the acquired sound signal into a control instruction according to a corresponding relationship between a preset sound frequency and the control instruction; and sending the control instruction to a multimedia controller so as to enable the multimedia controller to execute the control instruction.

Description

technical field [0001] The present disclosure relates to the field of wireless control, in particular, to a multimedia control method and device, a function key and a vehicle. Background technique [0002] Most of the current vehicles are equipped with a multimedia system, and people can listen to music, radio, video and other content through the vehicle multimedia. With the development of LCD screen technology, in-vehicle multimedia has also begun to use touch screens to replace part of the button operations. The control buttons of the multimedia system are reserved for less and less layout space when the car leaves the factory. [0003] However, in some scenarios, using traditional function keys for multimedia control is a safer and more convenient choice than using a touch screen for multimedia control. For example, if you don’t have the energy to confirm the position of the virtual keys on the touch screen during intense driving, there may be potential safety hazards wh...
