When the rotor takes one position, the reed switch is turned on under the influence of the magnetic field of the strong magnetic field generating section, and the specific frequency band is attenuated by the capacitor; In some cases, the rotor takes the reed switch to the other position where the magnetic field of the strong magnetic field generating section does not affect the reed switch, turns off the reed switch, and disables the attenuation effect of the specific frequency band by the capacitor. Speaker frequency characteristic switching device.
