1. A speaker, comprising:
a housing comprising an accommodating space and a rear cavity space, the accommodating space being communicated with the rear cavity space, an area in the accommodating space communicating with the rear cavity space being an airflow area;
a carrying board disposed in the accommodating space;
a magnetic component disposed on the carrying board;
a magnetic conductive component disposed at the magnetic component;
a voice coil disposed in the magnetic component and the magnetic conductive component; and
a diaphragm component disposed in the accommodating space, the diaphragm component being connected to the voice coil;
wherein, the magnetic component disposed in the airflow area comprises a first demagnetization configuration or/and the magnetic conductive component disposed in the airflow area comprises a second demagnetization component;
wherein an area outside the airflow area of the accommodating space is a non-airflow area; wherein when the airflow area and the non-airflow area have the same size, a magnetic flux of the magnetic component and the magnetic conductive component disposed in the airflow area is smaller than a magnetic flux of the non-airflow area.
