Abstract

The invention relates to a device and a method for controlling vehicle audio volume. The device comprises a loudspeaker sensor used for sensing the whistle of the vehicle, an audio regeneration part used for regenerating the audio signal relevant to wireless devices, a CD player and other devices, a micro processor used for increasing and outputting the volume level of the audio signal regenerated from the audio regeneration part, an audio processing part used for receiving and amplifying the audio signal from the micro processor, processing the audio signal into an audible signal, and outputting the audio signal, and a loudspeaker used for receiving the audio signal from the audio processing part and outputting the audio signal. By adopting the device and the method for controlling vehicle audio volume, when the vehicle whistles during the use of the vehicle audio device, the music or audio signal from wireless devices or other audio devices can not be interrupted owing to the loudspeaker.

Description

technical field [0001] The present invention relates to a vehicle audio device, more particularly to a vehicle audio volume control device capable of instantaneously increasing the audio volume when the whistle is blown during the operation of the vehicle audio device and a method thereof. Background technique [0002] Compared with the early automobile, which was a means of transportation for the purpose of moving since the invention of the automobile, the current automobile has become an aggregate of all technologies such as machinery, electronics, and chemistry. It is expected that the development of future technologies will be beyond what is currently possible. expected. With the development of this technology, the automobile has been fixed as an indispensable culture in our life, and external interference should be minimized in this independent cultural space. Therefore, in order to be able to listen to music or news while the car is driving, an audio device is install...
