The invention discloses a vehicle-mounted music partition sound insulation system and an automobile. The system comprises a vehicle-mounted music module which is used for outputting a vehicle-mounted music sound signal; a sampling module which is connected with the vehicle-mounted music module and is used for sampling the vehicle-mounted music signal and outputting a sampling signal; a noise reduction module which is connected with the sampling module and is used for outputting a coherent wave noise reduction signal according to the sampling signal; a first music playing module which is connected with the vehicle-mounted music module and is used for receiving the vehicle-mounted music sound signal and playing music; and a plurality of second music playing modules which are connected with the noise reduction module and are used for receiving the coherent wave noise reduction signals and playing coherent waves corresponding to the music played by the first music playing module. When the vehicle-mounted music is played, one or more second music playing modules are started, so that the generated coherent waves are counteracted with the played music, and partition sound insulation in the vehicle is realized. According to the invention, partition sound insulation is realized when the vehicle-mounted music is played, and the differentiated requirements of different passengers on the vehicle-mounted music are met.
本发明公开了一种车载音乐分区隔音系统及汽车,该系统包括:车载音乐模块,用于输出车载音乐声音信号;采样模块,与车载音乐模块连接,用于对车载音乐信号进行采样、输出采样信号;降噪模块,与采样模块连接,用于根据采样信号输出相干波降噪信号;第一音乐播放模块,与车载音乐模块连接,用于接收车载音乐声音信号并进行音乐播放;若干第二音乐播放模块,与降噪模块连接,用于接收相干波降噪信号并播放与第一音乐播放模块所播放音乐对应的相干波。播放车载音乐时,通过启用一个或多个第二音乐播放模块,使产生的相干波与播放的音乐相抵消,从而实现车内的分区隔音。本发明实现了车载音乐播放时的分区隔音,满足了不同乘客对车载音乐的差异化需求。
