[0032] As described in the background technology, currently, a stereo is a device for amplifying and playing sound. Existing stereos include active speakers (such as horns), passive radiators (English full name: passive radiator, English abbreviation: PR, also known as passive radiator) and a stereo cabinet, wherein the active speaker is fixedly mounted on the stereo cabinet, and the passive radiator is fixedly mounted on the stereo cabinet and used in conjunction with the active speaker to enhance the low-frequency effect, improve the sound output efficiency, and reduce the distortion of the active speaker, thereby improving the sound quality and audio of the stereo. The passive radiator in the existing stereo is usually directly glued to the stereo cabinet with glue, but when the stereo is in use, the vibration generated by the active speaker will be transmitted to the stereo cabinet, and the vibrating stereo cabinet will drive the passive radiator to shake together. This installation method causes the passive radiator to be easily displaced after a period of use, thereby affecting the frequency response and low-frequency performance of the stereo.
