FIG. 1 is a functional block diagram of a vehicle music partition sound insulation system according to an embodiment of the present invention;
fig. 2 is a schematic view of an operation flow of the vehicle-mounted music partition sound insulation system according to an embodiment of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, the technical solutions of the embodiments of the present disclosure will be described clearly and completely with reference to the drawings of the embodiments of the present disclosure. It is to be understood that the described embodiments are only a few embodiments of the present disclosure, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the disclosure without any inventive step, are within the scope of protection of the disclosure.
Referring to fig. 1 and 2, an in-vehicle music partition sound insulation system includes:
the vehicle-mounted music module is used for outputting vehicle-mounted music sound signals;
the sampling module is connected with the vehicle-mounted music module and used for sampling the vehicle-mounted music signal and outputting a sampling signal;
the noise reduction module is connected with the sampling module and used for outputting coherent wave noise reduction signals according to the sampling signals;
the first music playing module is connected with the vehicle-mounted music module and used for receiving vehicle-mounted music sound signals and playing music;
the plurality of second music playing modules are arranged in the vehicle in a partitioned manner, connected with the noise reduction module and used for receiving the coherent wave noise reduction signals and playing coherent waves corresponding to the music played by the first music playing module;
