Vehicle-mounted audio playing method and apparatus, multimedia host, and storage medium

A vehicle-mounted audio playing apparatus, comprising:

• a mobile microphone, a receiver, a multimedia host, a power amplifier, and an out-of-vehicle speaker;
• the multimedia host being configured to obtain, through the receiver, a first voice signal collected by the mobile microphone;
• and
• the multimedia host being further configured to:
• when the vehicle-mounted audio playing apparatus is in an out-of-vehicle karaoke mode, fuse the first voice signal and an accompaniment signal, and output a fused signal to the out-of-vehicle speaker after performing amplification processing through the power amplifier, to drive the out-of-vehicle speaker to produce sound.

A multimedia host for a vehicle-mounted audio playing apparatus, comprising a processor and a non-transitory computer-readable storage medium storing instructions executable by the processor to cause the multimedia host to perform operations comprising:

• obtaining, by the multimedia host, a first voice signal collected by a mobile microphone;
• when the vehicle-mounted audio playing apparatus is in an out-of-vehicle karaoke mode, fusing, by the multimedia host, the first voice signal and an accompaniment signal, and outputting a fused signal to an out-of-vehicle speaker after performing amplification processing through a power amplifier, to drive the out-of-vehicle speaker to produce sound;
• when the vehicle-mounted audio playing apparatus is in an out-of-vehicle lecture mode, outputting, by the multimedia host, the first voice signal to the out-of-vehicle speaker after performing amplification processing through the power amplifier, to drive the out-of-vehicle speaker to produce sound;
• when the vehicle-mounted audio playing apparatus is in an in-vehicle karaoke mode, fusing, by the multimedia host, the first voice signal and the accompaniment signal, and outputting a fused signal to an in-vehicle speaker after performing amplification processing through the power amplifier, to drive the in-vehicle speaker to produce sound;
• and
• when the vehicle-mounted audio playing apparatus is in an in-vehicle lecture mode, outputting, by the multimedia host, the first voice signal to the in-vehicle speaker after performing amplification processing through the power amplifier, to drive the in-vehicle speaker to produce sound.
