Abstract

The disclosure relates to an automatic frequency matching karaoke method and device and a vehicle, wherein the method and device are applied to the vehicle provided with a sound collector and a player. The method comprises the following steps: sending a first frequency matching signal to the player through the sound collector according to a preset frequency matching frequency, the first frequencymatching signal comprising a first modulation frequency; receiving a first frequency matching signal through the player according to the frequency matching frequency; setting the demodulation frequency of the player as a first modulation frequency, and sending a first modulation signal to the player through the sound collector; mixing an audio signal obtained by demodulating the first modulation signal according to the demodulation frequency with a preset accompaniment signal through the player to obtain a karaoke signal, and playing the karaoke signal. According to the invention, automatic frequency matching of the sound collector and the player can be realized without manually adjusting the demodulation frequency of the player by a vehicle owner, so that the purpose of vehicle-mounted karaoke is achieved; the operation is simple, and the karaoke experience of a user is improved.

Description

technical field [0001] The present disclosure relates to the technical field of video and audio data processing, and in particular, relates to a method, device and vehicle for automatic frequency karaoke. Background technique [0002] With the development of social economy and the improvement of living standards, the entertainment function has become one of the important references for people to buy cars. As a popular entertainment function, the car karaoke function has become a hot field of vehicle development. In the prior art, the car karaoke function is mainly through the wireless connection between the car FM (English: Frequency Modulation, Chinese: Frequency Modulation) microphone and the car radio to realize the car karaoke, and the car FM microphone and the car radio need to be frequency-paired to establish Wireless connection, the current car FM microphone is divided into fixed frequency band microphone and adjustable frequency microphone. Using FM fixed frequency ...
